订书机外壳注射模设计(注塑模毕业设计)【含CAD图纸、说明书
订书机外壳注射模设计 摘要:本毕业设计说明书详细介绍订书机外壳塑件的注射模设计。主要内容是材料(聚丙稀PP)特性分析,塑料注射模的结构设计、标准件的选择、模具材料选择、典型零件的数控加工3G程序代码编程设计。该塑件外表面要求达到境面,内部有弯曲的加强肋,底部进行文字加工,不但有外侧抽芯成型两个圆柱孔、两个半圆柱孔及圆柱孔旁边的浅孔,还有内侧抽芯成型内部四个突台。外侧抽芯距离短,模架小,在型腔板上固定弯销来实现侧抽芯。由于塑件中部有两不易成型的圆肋,采用了增加两个小型芯镶件的办法减少加工模具的难度。整体外形为曲面,不能用传统的加工工艺,而是在Pro/E建模的基础上电火花成型。关键词: 订书机外壳;注射模设计;侧抽芯;曲面The Design of the Book Sewer outside Shell Injection Mold Abstract: This graduate design instruction book has introduced the design of the book sewer outside shell injecting molding in detail. It mainly contains the analysis of property of the material (polypropylene PP), the structural design of injection mold, the selection of standardized part and the material of injection mold, the 3G code NC part programming for typical part. The surface of this plastic part should be mirror finished. The inside of it has bending reinforcing rib. The bottom of it should be worked with words. It not only has two cylindrical pore、two half cylindrical pore and short-hole beside the cylindrical pore that should be formed by outside extracting part, but also has four lug formed by inside extracting part. The distance of extracting is short and the mould is small, so fixing angle block on the cavity die is to finish outside extracting. Because the inside of the plastic part has two round ribs that are difficult to be formed, two inserts are added to make it easier to form mold. The integral surface is camber. It cant be formed by conventional job operation, so spark machine is needed to form it on the basis of Pro/E molding foundation.Key words : book sewer; design of injection mold; outside extracting; camber
