Description
本发明涉及压铸模具技术领域，具体为一种用于电机壳体的预热型压铸模具。
通常电机壳体采用压铸的工艺进行制造，压铸是一种金属铸造工艺，其特点是利用模具内腔对融化的金属施加高压，模具通常是用强度更高的合金加工而成的，铸造设备和模具的造价高昂，因此压铸工艺一般只会用于批量制造大量产品。
传统压铸工艺主要由四个步骤组成，或者称做高压压铸。这四个步骤包括模具准备、填充、注射以及落砂，它们也是各种改良版压铸工艺的基础。在准备过程中需要向模腔内喷上润滑剂，润滑剂除了可以帮助控制模具的温度之外还可以有助于铸件脱模。但现有技术中，在压铸模具中常常由于过多的添加润滑剂，导致铸件表面缺陷、滞流(浇不满)、冷疤以及不连续性，影响铸件的质量，而且现有压铸模具存在模具热疲劳龟裂失效问题，由于压铸生产时，模具反复受激冷激热的作用，成型表面与其内部产生变形，相互牵扯而出现反复循环的热应力，导致组织结构二损伤和丧失韧性，引发微裂纹的出现，并继续扩展，一旦裂纹扩大，还有熔融的金属液挤入，加上反复的机械应力都使裂纹加速扩展。
