A combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding, mainly comprising a concave mold with a variable cavity composed of a concave mold composite substrate,

Classification of plastic molds

Punching needle, punch, guide pillar, guide sleeve, top rod, top pin, driver cylinder, steel ball sleeve, independent guide pillar, slider, date stamp, inclined top slider, gate sleeve (rubber sleeve), positioning block, guide fixing block, guide pillar auxiliary device (positioning pillar), guide pillar component, etc.

Mold design and manufacturing are closely related to plastic processing. The success or failure of plastic processing largely depends on the effectiveness of mold design and the quality of mold manufacturing, and plastic mold design is based on the correct design of plastic products.

The design of air extraction holes for vacuum forming is the key to mold design. The air extraction holes should be located at the last place where the sheet is attached to the mold,

Due to the large variety and specifications, complex shape, and low surface roughness value, the manufacturing of molds is difficult. The deformation generated after mold heat treatment will seriously affect the quality and service life of the mold. Once it cracks during heat treatment, it will cause the mold to be scrapped. Therefore, reducing and preventing mold heat treatment deformation and avoiding its cracking is an important research topic for mold heat treatment workers. This article bri
