Description

A rapid prototyping injection mold

technical field

The utility model relates to the technical field of injection molds, in particular to a rapid-forming injection mold.

Background technique

Today's injection molds generally cool the injection molding raw materials first and then perform the ejection operation during injection molding. In this way, sometimes the product will have ejection marks due to incomplete cooling during ejection, which will affect the appearance of the product in the slightest, and in severe cases. affect product quality. Today's mold injection molding is generally a product injection molding with a simple structure. When a product with a complex structure is required to be injected, the raw material enters the gating system and is extremely easy to solidify in the middle. In order to solve this problem, some people add an insulation layer to the mold. Although the insulation layer can be The raw materials are injected into the mold smoothly, but this prolongs the cooling time and the production time of the product, which is not conducive to the needs of production and processing. Therefore, a rapid prototyping injection mold is proposed.
