1、 毕业设计(论文) 单层磁选机的设计 学 院： 机械工程学院 专 业： 机械设计制造及其自动化 姓 名： 学 号： 指导教师： 2010 年 6 月 摘要 - I - 摘要 此论文主要讲述的是注塑机的设计，它是成型塑件的一种重要工艺装备。注塑成型 是利用塑料的可挤压性和可模塑性，使粘流状态熔体在一定压力的闭合模具中成型具有 一定形状和尺寸的塑件制品。此设计为为一盒体的外壳。根据其技术要求和使用要求， 选择塑料种类为 ABS，再根据塑料的形状和生产批量，选择 SZ-300/160 注塑成型机。 由于该塑件的侧抽芯较长，所以采用液压抽长型芯机构，该系统有较大优点，其液压抽 拔力大，运动平稳。 此模

2、采用一模一腔， 一次分型脱出塑件。 型芯和型腔采用冷却水槽结构的冷却系统， 采用气塞排气，可有限避免缺陷。在确定模具结构方案后，绘制模具装配图，并进行计 算。最后绘制模具非标准零件图，经全面审核后投产制造。 关键词：注塑模具，盒形件，型芯，单型腔 Abstract - II - Abstract This paper is talking about the design of injection moulds; which is an important equipment of plastic forming. Injection molding is to make glutinous

3、fusibility form required plastic product with designed shape and size in closed moulds under needed pressure by means of plastic extrusion and plasticity. The plastic product is a outer covering for a box body. According to its technical request and used request, ABS is to be closed as its material.

4、 According to its designed shape and the numbers of the products, we choose the sz-300/160 cast shaper. At the same time, we use the hydraulic pressure to pull out the long core organization which is steady for the long core. This mold uses a mold cavity, a minute leaves models. The core and the cavity uses the cooling water system, tuck to exhaust the gas, but avoids the flaw. After ascertaining the project of the structure of the mould, protract mould-fitting drawing. At last, carry out
