Abstract

The invention discloses an overflow type injection mold. The overflow type injection mold comprises a front mold core and a rear mold core; a cavity is formed in the rear mold core; an insert in arranged in the cavity; a first plug-in unit is arranged at the rear of the insert; a second plug-in unit is arranged in the front mold core; the second plug-in unit is plugged in a front groove of the insert; the front mold core and the rear mold core are fixed through screws; a sealing ring is arranged in a gap between the insert and the cavity; and silicon rubber is arranged between the sealing ringand the second plug-in unit. The problems of burrs, flashes and the like of surfaces of products are solved, and the surfaces of the products are attractive; meanwhile, the problems of bubbles, cavities, glue deficiency and the like due to poor exhausting are solved; and the overflow type injection mold is simple in structure, the products are good in quality and stable, standard mass productioncan be implemented, the processing cost is low, and the production efficiency is high.

Description

technical field [0001] The invention relates to an improvement of an injection mold, in particular to an injection mold that can solve the problems of product surface burrs, flashes, etc.; meanwhile, solves the problems of air bubbles, air pockets, lack of glue, etc. caused by poor exhaust; the structure is simple, and the product quality is improved. Good and stable overflow injection mold that can be standardized for mass production, low processing cost and high production efficiency. Background technique [0002] In the prior art, the products produced by injection molds are prone to problems such as surface burrs and flashes; at the same time, there are problems such as air bubbles, air pockets, and lack of glue caused by poor exhaust; product quality is unstable and cannot be standardized for mass production. [0003] To this end, we have developed a product that can solve the problems of surface burrs and flashes; at the same time, it has solved the problems of air bub...
