Plastic mold in the production process due to the role of the injection pressure deformation dislocation, too much pressure exerted on the sliding part of the mold to produce the phenomenon of bite, so the rigidity of the mold to be large. Note that the mold each part of the screws to tighten, solid. It is hoped that the sliding part of the quenching process, so that the sliding part has sufficient hardness.
First, the cause of sliding mold:
1 mold sliding part of the lubrication problem;
2 mold sliding part of the hardness;
3 deformation of the sliding part of the mold.
Two, to prevent the plastic mold bite method:
1.In the 1 part, using sliding copper powder MoS2 lubricant;
2 to the sliding part of the quenching process, using all the groove of the mold to strengthen the check;
3 sliding parts are made of steel and copper with different materials to prevent bite.
