Abstract

The invention relates to a mold core shape follow-up water way device and mold cavity shape follow-up water way device for an injection molding pipe fitting mold. All point locations of a mold cavityare followed by water ways, therefore, it can be guaranteed that the overall temperature of the mold cavity keeps uniform, a product is uniformly cooled, and buckling deformation caused by non-uniformcooling can not occur; meanwhile, shape follow-up water ways are arranged in a mold core, it is guaranteed that the temperature of the inner wall of the product is uniform, uniform cooling is achieved, therefore, the product quality is improved, the production cycle is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding molds for pipe fittings, in particular to a mold core conforming waterway device and a cavity conforming waterway device for injection molding pipe fittings. Background technique [0002] The injection mold for pipe fittings is used to integrally form pipe fittings. The general mold for making pipe fittings includes a fixed mold, a moving mold and a core-pulling mechanism. The fixed mold is provided with a cavity, and the core-pulling mechanism includes a core and a driver. A gap is formed between the core and the cavity, and the shape of the gap is the same as that of the pipe fitting. The molten material is passed into the gap, cooled and shaped by the cooling system, and finally the cooled pipe fitting is released. [0003] As mentioned above, in the injection mold, the cooling system is the core part, which has an important impact on the life of the mold and the production efficiency...
