接线柱的注塑模具设计及成型工艺-注射模含12张CAD图+说明书

塑件图

摘要
本次设计的是塑料接线柱塑料模具，体现了典型塑料模的设计要求、内容及方向，有一定的设计意义。通过对该模具的设计，加强了设计者对塑料模设计基础知识的理解和运用，为设计更复杂的塑料模具做好了铺垫。
本设计运用塑料模具工艺及模具设计的基础知识，首先分析了产品的性能要求，并选定合适的材料，然后进行了型腔分布设计以及三维立体建模，以选取合适的分型面；最后分析了产品的特征，便于确定模具的设计参数、设计要点及卸件装置。
本设计采用了一模八腔的结构。成型原理如下：首先将松散的粒状或粉末状成型物料从注塑机的料斗送入高温的机筒内加热、熔融、塑化。使之成为黏流溶体，然后再柱塞或螺杆的高压推动下，以很大的流速通过机筒前端的喷射嘴注射进入温度较低的闭合模具中，经过一段时间的保压冷却定型时间后，即可取出注射成型的塑胶接线柱。
成型过程如下:动定模板合模后，由注塑机注射将已加热到熔融状态的材料注射入型腔，经过主流道分流道，充满型腔后，经过一定的冷却保压后，动定模板分离，侧抽芯机构工作，抽芯完成后，压力机推动推板用顶杆推出制件，手动取出即可。

English abstract

This design is about plastic binding post mold.it presents the typical plastic mold design requirements.there is a great significant in the concent and the directions.bydesigning the mold,it strengths the comprehension and using about the basic knowledge of designers.This is a good bedding to design the more complexplastic mold.
The design uses basic knowledge of plastic mold art.and mold designing.At first,we analyze the products performance.and select the proper material and then design the mold cavityand it’s distribution.three dimension molding to choose the proper mold joint.At last,analyze the character of the product.In order to identifythe design,data is the keypoint of the design and the equipment of the products.
The design use the construction of exactlyeight cavity,these are the principle,first,we send the inattentive particulate matter and powder matter to the high heat machine hopper to heat,melt,and make them into dissolve matter,and then under the high pressure of plunger and screw,theygo in a quick speed,through the melting jet in the head of the machine shotting the lower closed model.After the pressure of dynamic fixed clamping becomes cold.We canwithdrawthe fashioned binding post.
Following are the processes:the shot machine send the materials to the melting stoves.Passing bythe primaryand the secondaryroads.Fillingwith the mold and after the cold pressure,theyseparated.The side core-pulling began towork.When it comes to an end,the pressure machine push the knockout plate,and then,withdrawitwithyour hand.

The keyword：plastic mold、material、Exactlyeight cavity、Side core-pulling、Forming principle、Molding process
