塑胶模具有哪些常用的冷却方式?
产品在注塑成型时,模具的温度会影响塑胶的成型周期,从而影响生产效率。为了提高工作效率,模具需要设计冷却系统。那么,塑胶模具常用的冷却方式有哪些呢?https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/a0f31f3c615d4a7a8227b9d4c8187d9a~tplv-tt-large.image?x-expires=1969610807&x-signature=y%2ByOow45vzE8ZiwnhAAeSmNes28%3D
解决方法:
1、在模具设计中,对于高低落差小或者呈平板形的产品,一般采用回字形水路冷却,如下图所示:

2、对于高低落差小,但是长度方向较长的产品,采用回字形水路中间加水井冷却的方式,如下图所示:

3、有些产品高低落差很大,导致回字形水路无法达到冷却的效果,此时通常采用普通运水加水井冷却的方式,如下图所示:

4、有些产品型芯细长,外观要求较高,需要采用喷管式运水冷却,如下图所示:

5、对于一些较长的型芯,为了保证冷却效果,除了采用水井冷却以外,还可以采用螺旋运水冷却,如下图所示:
