Description

Technical Field

[0001] This utility model relates to the field of raw material tape plastic core technology, specifically, to a raw material tape plastic core injection mold. Background Technology

[0002] PTFE tape is made of expanded polytetrafluoroethylene (ePTFE). Due to its mesh-like expanded structure composed of fine long fibers and nodes, PTFE tape has good toughness, high longitudinal strength, and easy transverse deformation. It is widely used in the installation of pipes requiring sealing in building water supply, heating, drainage, fire protection, heating, gas, and air conditioning systems. Injection molds are tools for producing plastic products and also tools for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts. Specifically, it refers to injecting molten plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying it to obtain the shape.

[0003] In the existing technology, during the injection molding process of raw material strip plastic core, workers need to manually remove the plastic core from the mold, which greatly reduces work efficiency. In addition, the natural cooling during material removal will affect the material removal rate.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
