Dwivedi d wei the Submitted to the original ASME/JDSMC Special Issue on Sensors in the injection molding is a production of thermoplastic plastic products manufacturing process, the most popular and mold design is an important aspect of the process. Mold design require

3、s professional knowledge, skills and, most importantly, experience in the field. All three are indispensable. Manufacturing plastic components requires selecting the right molds, and if one is lacking, this option is based on repeated trials. This increases production costs and creates inconsistenci

4、es in design. This paper introduces the development of intelligent mold design tools. This tool captures the knowledge of the mold design process and reflects the knowledge in a logical way. The knowledge gained will be deterministic, but the information in the design process is uncertain. Once the

5、mold design tool is developed, it will guide the user to select the appropriate mould for the plastic parts according to the requirements of different customers. The process of injection molding process requires professional knowledge, skills and, above all, the practical experience of success. It i

6、s usually the efficiency of process parameter control process. In the manufacturing process, effective control and optimization of these parameters can achieve consistency, which can be expressed in the quality of parts and parts cost. 1 intelligence engineering module of injection molding process (

7、IKEM) injection molding process based on knowledge of intelligence engineering modules (IKEM) is a software technology, it ahead of concurrent engineering and CAD/CAM system. It integrated engineering design and manufacturing process of new knowledge, to the user instructions, the design of various

8、through reduce the engineering change in product development and design stage, help to reduce working hours. The system will be used for injection molding design, design iteration and process integration. The current process consists of a number of manual computations, CAD graphic structures, and th

9、ree parts from previous projects. Once the engineer has completed the design, this will be a performance evaluation. The IKEM project is divided into three modules. 1 cost estimating module 2 mold design module 3 production module IKEM system has two forms of input. In the form of a CAD model (Pro/E

10、 file), enter in the form of the user interface given. Figure 1-1 illustrates the type of input and user output that enters each module. The manufacturers experience level will determine how to control the process parameters effectively. Sometimes this leads to inconsistencies caused by human error.

11、 There is also the lack of experience, the lack of time, the lack of resources and the lack of space for innovation. By creating a so-called intelligent model, the problem of engineering knowledge provides a feasible scheme to solve all this user input form design and manufacture die set user output

12、 syntax analysis process CAD model cost estimate figure 1-1 of tissue engineering IKEM 2 intelligent mold design tool In its Basic form in the mold design tool is a extracted from text file input Visual Basic application, this text file contains about parts and input from the user program. The text

13、file contains the geometry parsing of the parts of an information file from Pro/E. Input is used to estimate the size of the mold and other properties. 2.1 the literature review mold design is another stage of injection molding process. Experienced engineers can help automate the process to a large

14、extent and improve their efficiency. This problem requires careful study of the time of design mold. Typically, when design engineers design molds, they refer to tables and standard manuals, which can take a lot of time. In addition, it takes a lot of time to consider the modeling components of the

15、mold in standard CAD software.Different researchers have solved the problem of shortening the time spent designing the mold in different ways. Kell and James use group techniques to reduce mold design time. The unique coding system that aggregates a class of injection moulds and the tools needed in

16、injection moulds has been developed, which can be applied to other product lines. Software systems that implement coding systems have also been developed. By acquiring the experience and knowledge of engineers in this field, try to automate the process of mold design directly. The research and devel

17、opment of parallel mold design system is such a process that in the parallel engineering environment, it is attempted to develop a system of injection mold design process. Their research goal is to develop a conducive to mold the development process of concurrent engineering practice, and research a

18、nd development of a knowledge-based for injection mold design process problems and aided design of product requirements. The researchers have been trying to automate the mold design process by obtaining information and uncertainty information about the mold design process in various ways. The resear

19、ch attempts to develop a unique mold design application that takes information in two forms of certainty and uncertainty. 2.2 methods to develop intelligent mold design tools, traditional mold design methods are studied. Application developers and design engineers collaborate to design a mold for a

20、specific plastic part. During this time, the method used by the engineer to select the model base is being closely watched and sifted through various aspects of the process, requiring his knowledge to be determined. In addition, sometimes engineers will refer to charts and manuals to standardize the

21、ir selection process. This takes time and is later recorded in the application. The systems interpretation of the input and output applications is the next phase. This involves defining what the user needs most of the mold layout information, and the minimum input to get the same output. According t

22、o the information gathered in the mold design work, the conventions followed by engineers are translated into if-then rules. A decision table is used to explain a variety of situations that may arise when a particular aspect of a mold design project is addressed. This is set up and then organized in

23、 a mutually integrated module using the application development environment. Finally, the application verifies its correctness, when it involves designing molds for plastic parts in industrial production. 2.3 select the appropriate die set Under normal circumstances, select the appropriate die set f

24、or manufacturing plastic parts involved are: (1) the estimated number of cavity cavity quantity decision depends on the quantity of parts required, within a certain amount of time as the machine of plasticizing capacity, rejection rate and other issues can also affect the number of cavity die set. (

25、2) determine that the inserts and their size inserts help to reduce the production cost. When it comes to size and number of choices, making decisions depends on the existing set of reusability and the cost of the new set. (3) determining the size of the runner and the size of the cast-water path de

26、pends on the material being formed. Although there are other considerations to consider material properties to determine the size of the runner to meet its flow requirements. The positioning of the wheel depends on the topology of the flow. Although the loop runner system is always the best, the bal

27、ance of the branch system is the most widely used system to avoid the branch runner system. (4) determine the diameter of the runner diameter, determine the size of the mold, the number of cavity, or the total amount of plastic used to fill it in a certain amount of time. (5) the positioning plastic

28、 of the gate enters the cavity at some point, which can fill the cavity evenly. The gate can be located at any point in the circulation cavity, but when filling the rectangular cavity, it must flow from the middle. (6) determine the size of the water supply channel and locate the water supply channe

29、l and locate any wall in the mold from the standard distance. The convention does not locate watercourses on the wall of the mold with a diameter range.(7) based on the above conclusions, the size of the die will be estimated and rounded up to the nearest product directory number. In the case of the

30、 die frame, if the design is redesigned, considering all the above aspects will reduce the cost and reduce the design time, enter the redesign. 2.4 the proposed problems, need some knowledge and experience, the consumption of mold design time involves charts, tables, etc., for the development of app

31、lications as shown in figure 2-1. While most of the input, such as the number of cavity, cavity image size, cycle time, is according to customers requirement, other input, such as plasticizing capacity, injection quantity per minute, etc., can be obtained from the illustrations of the machines. The

32、output of the application contains the mold size and other information, which obviously helps to select the standard model in the directory. In addition to the input and output, figure 2 also shows the various modules that produce the resulting output. 2.5 in this stage, expert knowledge can be expr

33、essed through multiple forms of if - then statements. This rule can be a statement of qualitative and quantitative knowledge. Qualitative knowledge is a kind of information that solves the problem of computing. The so-called qualitative is to say the information about uncertainty, but merely as a ki

34、nd of applied rule on the basis of previous cases. A typical rule is as follows: the input of the main program with block size mold cavity dimension image size cold water way cycle time runner diameter size parts weight plasticizing capacity cavity number Injection quantity allowed time per minute o

35、utput cavity mould size runner size The gate size Cold water orientation figure 2-1 mold design module of organization If material acetal lt 3, distributary channel and distributary channel length length gt0, so end of distributary channel diameter 0.062 When set the rules, its important that we use

36、 a kind of rigorous way to show these information, at the same time to avoid repetition, incomplete and inconsistent phenomenon. The decision table can help address the above issues, which are implemented through the inspection of overredundant and extensive problem statements. For example, in the p

37、rocess of selecting the appropriate die frame, the size of the die depends on the number of cavity and inserts. To ensure that all shapes and inserts are considered, we use the decision table and then use the decision table to make the rules. Table 2-1 decision table sample cavity number, 4-trichlor

38、obenzene (1) 1 1 1 2 2 2 and 4 4 4 module number 1, 2, 4-trichlorobenzene (1) 4 1 2 4 1 2 4 mold size A A B A B C table 2-1 shows in more than one case, the size of the mould is the same situation A: mould width with block length 2; Length of die insert length 2; Thickness of mould thickness. Condit

39、ion B: die width 2 inset width 3.5; Length of die insert length 2; Thickness of mould thickness. Case C: die width 2 inset width 3.5; Length of die insert length 3; Thickness of mould thickness. Is a, the number of cavity insert is also a case and the number of cavity number two and four is the case

40、 with the same mold size, these three conditions can be summed up in one single rule: if the number of blocks 1, the die mold width (edge width 2) length (with block length 2) mold thickness end panel board thickness For the sake of convenience and clarity, with a standard modular programming langua

41、ge to these rules. Each module generates a set of outputs that will be input to other modules. 2.6 test applications have been verified by using various test cases for the application of smart mold design. For each case, there is a wide variety of information about the parts of the mold and machine,

42、 and human experts have confirmed the results of the input to the application. Table 2 shows a test that requires two molds and no inserts. The application provides approximate mold dimensions, the size of the execution, the size of the gate and the length of the second runner are based on the size

43、of the cavity drawing and other information.当其中的一个缺少合适的模具来制造一个塑料部件时，就会出现在一个错误的基础上。这增加了生产成本，并引入了设计上的不一致。摘要介绍了一种智能模具设计工具的开发。该工具是关于模具设计过程的知识，并以逻辑的方式来表示知识。获得的知识将是关于molddesign过程的确定性和非确定性信息。一旦开发出模具设计工具，将根据客户的不同要求，引导用户选择合适的模具。介绍注塑成型工艺要求知识专业知识和最重要的经验，使其成功实施。通常是控制过程效率的成型参数。在生产过程中，有效地控制和优化这些参数，可以达到质量和零件成本的一致性

44、。制造商的经验水平决定了如何有效地控制生产过程。这有时会导致人为错误导致的不一致。此外，在缺乏经验的情况下，缺乏时间资源和创新的余地很小。以知识为基础的工程为所有这些问题提供了一个可行的解决方案，它创造了一个被称为“智能模型”的问题。一种基于注塑成型工艺的智能知识工程模块，是一种比并行工程和cad/cam系统领先一步的软件技术。它集成了当前关于设计和制造过程的知识，通过减少产品开发设计阶段的工程变更，从而减少了几个工时，通过向用户提供各种设计方面的指导。该系统将用于注塑设计设计的迭代和过程集成。这个过程包括许多手工计算的CAD图形结构，从以前的项目中获得。一旦工程师完成了设计，就会对性能进行评估。伊克姆项目已经被划分为三个主要模块。1。成本估算模块2。模具设计模块3。“伊克姆”系统的制造模块输入有两种形式。在用户界面表单中输入以CAD模型为支持的文件和输入。图1演示了进入每个模块的输入和给用户的输出。图1所示。伊克姆项目2智能模具设计工具模具设计工具的基本形式是一个可视化的基本应用，它从一个包含关于部件和用户输入表单的信息的文本文件中获取输入。文本文件包含了从一个/e信息文件中解析的部分几何图形。该输入用于估计模具的尺寸和其他各种特性。2.模具的文献回顾是注塑成型过程的另一个阶段，在这个过程中，工程师的经验很大程度上帮助自动化过程，提高效率。
