Problems solved by technology

[0004] Since the injection mold is mainly aimed at increasing the filling strength of special parts in the cavity, it has certain limitations. When the part of the product that needs to increase the filling strength changes, the injection mold cannot flexibly adjust the filling strength of the corresponding part in the cavity. local cooling

Abstract

The invention discloses an injection mold. The injection mold comprises a mold body, an outer closed cavity, a cooling air pipe and a closing plug; the mold body is internally provided with a mold cavity; the outer closed cavity sleeves the mold body in a sealing mode; the cooling air pipe is arranged in the outer closed cavity; and the closing plug can transversely penetrate the outer closed cavity and the cooling air pipe simultaneously. According to the injection mold, not only can a special part in the mold cavity be locally cooled in a targeted mode, but also the local cooling effect on acorresponding part in the mold cavity can be flexibly adjusted, thus the filling strength of the relevant parts in the mold cavity is improved, internal stress in an injection-molded product is eliminated, the molding quality is greatly improved, and the qualification rate is greatly increased.

Description

technical field [0001] The invention belongs to the field of plastic products, and in particular relates to an injection mold. Background technique [0002] Plastic injection molding is a method of plastic products. The molten plastic is injected into the mold of the plastic product under pressure, and cooled and formed to obtain various plastic parts. Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structure of plastic molding machines and plastic products, the types and structures of plastic molds are also varied. [0003] The prior art (CN107116752A) discloses a multi-point nitrogen-filled plastic mold injection molding process, please refer to the attached figure 1 , figure 1 It is a schematic diagram of the injection mold structure of the multi-point nitrogen-filled plastic m...
