一、问题的提出 目前塑料制品模具的加工还处于手工或半机械化的状态,注塑凉鞋模具就是一个典型。其制作工艺落后,造价高、生产周期长,鞋面和鞋带刻花在无规则的凹面进行,手工制作需要高级技工。因此,使生产发展受到很大的限制。 目前注塑凉鞋模具使用铝合金或45钢等材料,耐腐蚀性能差,硬度低,一般使用寿 First, the issue put forward At present, plastic mold processing is still in manual or semi-mechanized state, injection molding sandals mold is a classic. Its production process behind, high cost, long production cycle, carved upper and laces in irregular concave, hand-made need for senior technicians. Therefore, the development of production is greatly restricted. Sandals injection mold currently used aluminum or 45 steel and other materials, poor corrosion resistance, low hardness, the general service life
