发布人:管理员   发布时间:2020-6-29

塑料井盖模具的工作条件一般须在150°C-200°C下进行工作,除了受到一定压力作用外,还要承受温度影响。

The working condition of the plastic well cover mould is generally 150 ° C-200 ° C, which is not only affected by certain pressure, but also by temperature.

现根据塑料井盖模具使用条件、加工方法的不同将塑料井盖模具的要求总结如下:足够的表面硬度和耐磨性塑料模的硬度通常在50-60HRC以下,经过热处理的模具应有足够的表面硬度,以保证模具有足够的刚度

According to the different use conditions and processing methods of plastic well cover mould, the requirements of plastic well cover mould are summarized as follows: the hardness of enough surface hardness and wear resistance plastic mould is generally below 50-60hrc, and the mould after heat treatment should have enough surface hardness to ensure that the mould has enough rigidity

                      

模具在工作中由于塑料的填充和流动要承受较大的压应力和摩擦力,要求模具保持形状的精度和尺寸精度的稳定性,保证模具有足够的使用寿命。因此提高模具的硬度有利于提高其耐磨性。

Due to the large pressure stress and friction in the filling and flow of plastic, the mold is required to maintain the shape accuracy and dimensional accuracy stability, so as to ensure the mold has sufficient service life. Therefore, increasing the hardness of the die is conducive to improving its wear resistance.

为延长切削刀具的使用寿命,提高切削性能,减少表面粗糙度,塑料井盖模具硬度必须适当。良好的抛光性能高品质的塑料制品,要求型腔表面的粗糙度值小,为此选用的材料杂质少、组织微细均一、无纤维方向性、抛光时不应出现麻点或桔皮状缺陷。

In order to prolong the service life of cutting tools, improve cutting performance and reduce surface roughness, the hardness of plastic mould must be appropriate. Good polishing performance, high-quality plastic products, the surface roughness of the cavity is required to be small, so the selected material has less impurities, fine and uniform microstructure, no fiber directionality, and there should be no pockmarks or orange peel defects during polishing.
