Plastic Deformation Failure
塑料模型腔表面受压、受热可引起塑性变形失效,尤其是当小模具在大吨位设备上工作时,更容易产生超负荷塑性变形。塑料模具所采用的材料强度与韧性不足,变形抗力低;塑性变形失效另一原因,主要是模具型腔表面的硬化层过薄,变形抗力不足或工作温度高于回火温度而发生相变软化,而使模具早期失效。
Plastic deformation failure can be caused by pressure and heat on the surface of plastic model cavity, especially when small dies work on large tonnage equipment, it is easier to produce overload plastic deformation. Another reason for plastic deformation failure is that the hardened layer on the surface of the die cavity is too thin, the deformation resistance is insufficient or the working temperature is higher than the tempering temperature, which causes the phase transformation softening and causes the early failure of the die.
