摘要
此毕业设计课题的制品名称为“盖板”，用于密封作用。
制品材料为：ABS,此制品是批量生产，本产品的成型工艺采 用注射成型，产品材料为：乳白色ABS,即丙烯睛一丁二烯一苯 乙烯共聚物。
我将设计一套塑料成型模具，材料为ABS。在设计模具时需要考 虑制品的一些特点。制品的主要特点是上表面平整，下表面四周高中 间低，其上表面有一个空心圆柱。
由于塑件尺寸不大，采用一模两腔，双分型面，能够适应生产的 需要，满足大的经济效益，浇口去除方便，容易保证塑件的质量。开 模后，塑件包紧动模型芯的力比较大，采用推件杆推出，推出力比较 平稳，塑件不易发生变形。
本设计主要对以下几个部分进行设计，成型部分，浇注系统，导 向机构，推出机构，温度调节系统，排气系统，支承零部件。设计的 对向为注射模，要求精度高，寿命长。
关键字:一模两腔，推杆推出，双分型面。
Abstract
This design graduate of the products subject to the name of law-cap
for-conditioner, and other cosmetics bottle.
Materials for the products: pp (PP), the product of the material is
polypropylene pp. PP is a semi-crystalline materials. PE more than it
should be hard and have a higher melting point. Polypropylene is tasteless,
colorless, non-toxic. Look like polyethylene. However, a more
transparent and lighter than polyethylene. Density 0. 9-0. 91g/cm3. It is
non-absorbent, glossy, easy coloring. PP yield strength, tensile
strength, compressive strength, hardness and elasticity and better than
This is a mass product, so I will design a set of plastic mold. In the
mold design to consider some of the characteristics of the The main
products is characterized by its oval shape for the column, has been
carefully designed to meet its visibility and aesthetic This is the
plastic parts used in the conditioner bottle, it is a simple matter with,
so precision of Plastic size and surface roughness of certain
requirements to be bright and clean appearance may not have a scratch,
the overall size Moderate. This three-plate molds, plastic parts get to
the cylindrical surface, at the same time to prevent the open mode so
that when pieces of plastic have a scratch, so use pieces of board pushed
the introduction of plastic parts. As the size of small plastic pieces,
using a four-cavity mold, able to adapt to the needs of production to
meet th
