仪表开关盖板塑件成型工艺分析与模具设计(含CAD零件图装配图)(任务书,开题报告,论文说明书11000字,CAD图24张)
摘 要
本文借助计算机软件Auto CAD对仪表开关盖板塑件进行设计，对其可行的方案进行比较，最终选择最优方案。
对设计的多种方案进行了比较，其中一模四腔、摆杆侧抽芯、推杆顶出的方案选为最终的设计方案。
论文主要对仪表开关盖板塑件设计过程中模具设计的主要步骤进行论述。如设计时首先应该对成型零件进行工艺分析检查是否有阻碍出模的部分，其次根据生产要求考虑零件的成型排布，结合自己设计的模具整体结构设计浇注系统，根据零件所需排布位置设计固定支承零件，选择适合的推模机构及导向机构。同时因为我的模具还需要考虑侧分型机构设计。
设计结果基本满足设计要求，各机构运动过程不会出现相互干涉。
本文的特色：本文按照注塑模具设计的基本步骤对仪表开关盖板塑件进行设计，以二维绘图软件进行总装图和零件图的绘制和设计以及标注。
关键词：一模四腔；摆杆侧抽芯；推杆顶出；注塑成型
Abstract
In this paper, the plastic parts of instrument switch cover plate are designed with the help of computer software Auto CAD, the feasible schemes are compared and the optimal scheme is selected.
Several schemes are compared, including one mode four cavity, one swing rod side pulling core, and the putter ejection scheme selected as the final design scheme.
This paper mainly discusses the main steps of mould design in the design process of plastic parts of instrument switch cover.For example, when designing, the process analysis of the forming parts should be carried out first to check whether there are any parts that hinder the mold, and secondly, according to the production requirements, the forming arrangement of the parts should be considered, and the gating system should be designed in combination with the overall structure of the mould designed by oneself. Design the fixed support parts according to the layout position of the parts, select the suitable push die mechanism and guide mechanism. At the same time because my mold also needs to consider the side parting mechanism design.
The design results basically meet the design requirements, and the movement process of each mechanism will not interfere with each other.
The characteristics of this paper: according to the basic steps of injection mold design, the plastic parts of instrument switch cover plate are designed, and the drawing and design of assembly drawing and part drawing are carried out with two-dimensional drawing software.
Key Words：One mold four cavity; swing rod side pulling core; push rod ejection; injection molding.
