一般塑料模具由动模和定模两部分组成,动模安装在注射成型机的移动模板上,定模安装在注射成型机的固定模板上。在注射成型时动模与定模闭合构成浇注系统和型腔,开模时动模和定模分离以便取出塑料制品。
Generally, plastic moulds are composed of moving and fixed moulds. The
moving moulds are installed on the moving moulds of the injection
moulding machine and the fixed moulds are installed on the fixed moulds
of the injection moulding machine. In injection moulding, the gating
system and the cavity are formed by the closure of the movable and fixed
moulds, and the movable and fixed moulds are separated when the moulds
are opened to remove the plastic products.
模具的结构虽然由于塑料品种和性能、塑料制品的形状和结构以及注射机的类型等不同而可能千变万化,但是基本结构是一致的。模具主要由浇注系统、调温系统、成型零件和结构零件组成。其中浇注系统和成型零件是与塑料直接接触部分,并随塑料和制品而变化,是塑模中最复杂,变化最大,要求加工光洁度和精度最高的部分。
Although the structure of the mould may vary greatly due to the variety
and performance of plastics, the shape and structure of plastics
products and the type of injection machine, the basic structure is the
same. The die is mainly composed of pouring system, temperature
regulating system, forming parts and structural parts. Among them, the
casting system and the forming parts are the parts directly contacted
with the plastics, and change with the plastics and products. They are
the most complex and most changeable parts in the plastic mould,
requiring the highest processing smoothness and accuracy.
浇注系统是指塑料从射嘴进入型腔前的流道部分,包括主流道、冷料穴、分流道和浇口等。成型零件是指构成制品形状的各种零件,包括动模、定模和型腔、型芯、成型杆以及排气口等。
The pouring system refers to the runner part of the plastic before it
enters the cavity from the nozzle, including the main runner, the cold
material hole, the shunt runner and the gate, etc. Molding parts refer
to all kinds of parts that constitute the shape of products, including
moving die, die setting and cavity, core, forming rod and exhaust
outlet, etc.
