In order to facilitate installation and replacement, the flanging type plastic mold needs to separate the easily damaged inserts. Considering the problems of later assembly and adjustment, the inserts in the working part are preferably of retaining wall structure.

Under normal circumstances, the overhang of the knife block cannot exceed ten millimeters. If there are special requirements, both parties must determine in advance, and try to minimize the joint surface of the flanging knife and the shaping knife.

There should be no screw holes, pin holes or other holes in the working area. The positioning device needs to ensure its stability. Hole positioning is preferred among holes, shapes and contours.

Plastic shell

When working, there are always several parts of the mold with relatively large lateral forces. It is necessary to design a corresponding anti-lateral force structure. Its guide device is best to use an implanted guide column and a self-lubricating guide sleeve to keep the sleeve mouth and the lower surface of the upper mold base flush.

When selecting a pressing elastic element, the pressure should be calculated in advance to ensure that the pressure process is balanced and the material is fully pressed. In principle, the limit of the pressure plate adopts the method of working side pin plus safety side pin. At the same time, the foreign affairs office requires the addition of conical limit to prevent lateral force and crushing.

When arranging elastic elements, the balance of the pressure position and the pressure core should be considered. The part of the mold that needs to work cannot contact the material earlier than the pressure core. It is only allowed after the material is fully pressed to avoid too many problems.
