塑料模具材料要求
塑料模具材料要求
Requirements for Plastic Mould Materials
塑料模具的工作条件与冷冲模不同，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。现根据塑料成型模具使用条件、加工方法的不同将塑料模具用钢的基本性能要求大致归纳如下:
The working condition of plastic die is different from that of cold punching die. Generally, it must work under 150 C - 200 C. Besides being subjected to certain pressure, it must also bear the influence of temperature. The basic performance requirements of steel for plastic moulds are summarized as follows according to the different working conditions and processing methods of plastic moulds.
1、足够的表面硬度和耐磨性
1. Adequate surface hardness and wear resistance
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。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，保证模具井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 有足够的使用寿命。模具的耐磨性取决于钢材的化学成分和热处理硬度，因此提高模具的硬度有利于提高其耐磨性。
The hardness of plastic moulds is usually below 50-60 HRC. The heat treated moulds should have sufficient surface hardness to ensure that the moulds have sufficient stiffness. Because the filling and flowing of plastics must bear large compressive stress and frictional force in the work of the die, it is required to keep the shape accuracy and dimensional accuracy of the die stable, and ensure that the die has sufficient service life. The wear resistance of the die depends on the chemical composition of the steel and the hardness of heat treatment, so improving the hardness of the die is beneficial to improving its wear resistance.
