Injection mold convenient to demold

Abstract

The invention discloses an injection mold convenient to demold. The injection mold comprises an injection molding head, an injection molding pipe, an upper mold body and a lower mold body, the upper mold body and the lower mold body form an injection molding module, the injection molding pipe is installed at the outer side of the injection molding head, and the injection molding head is connected with the upper mold body and the lower mold body through the injection molding pipe; and a butt joint frame is arranged at the rear side of the upper mold and the rear side of the lower mold, a quick discharging device is arranged at the sides, away from the injection molding pipe, of the upper mold body and the lower mold body, a pressurizing inner injection pipe is arranged in the injection molding head, and butt joint mechanisms are arranged at the sides of the interiors of the upper mold body and the lower mold body. The invention relates to the technical field of injection molds. According to the injection mold convenient to demold, the problem that after injection molding of an existing injection mold is conducted, internal pressure and external pressure are different after an internal mold material is cooled, and consequently demolding of the mold cannot be carried out rapidly is solved, self pressure relief is completed, disassembly is convenient, the injection mold is easy and convenient to operate, and the integrity of the internal injection molding material of the injection mold cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for easy demoulding. Background technique [0002] In the field of injection molding, in order to realize the injection molding of the workpiece, the existing process is usually to place the pouring head in the mold, then close the mold, and inject plastic, etc. into the cavity of the mold through the pouring head. Generally, a section of runner is separately provided on the traditional pouring head, through which plastics are injected. However, the setting of the runners will easily lead to an increase in the injection pressure of the mold, which will cause the plastic to overflow and form waste, and the runners will easily break off from the pouring head, causing the mold to have a risk of compression molding. After the mold material is cooled, the internal and external pressures will be different, resulting in the inability to quickly demould the mol...
