The hot runner device is indispensable in mold design. It is designed according to the needs of the product, which can prolong the service life of the mold and improve the demolding effect of the product.

A plastic mold hot runner heating device, comprising a ring-shaped heating sleeve slidably mounted on an upper mold, a lower mold is arranged at the bottom of the upper mold, and the same molding cavity is opened on the upper mold and the lower mold, The top is provided with a first groove, the bottom of the first groove is provided with an installation groove, the bottom of the installation groove is connected with the molding cavity, the installation groove is provided with a hot runner pipe, the hot runner pipe is connected with the installation groove, and an annular heating sleeve The sliding sleeve is arranged on the hot runner pipe, and the annular heating sleeve is slidingly installed in the installation groove. (Plastic molding dies).

This new type of hot runner has a simple structure and convenient operation. The ring-shaped heating sleeve can be quickly disassembled through simple pulling and rotating actions, to facilitate replacement and effectively avoid the production efficiency caused by the aging of the ring-shaped heating sleeve. The problem of reduction brings great convenience to people. (Plastic Injection Mold Making).
