Injection molding die and method of automotive engine intake manifold

Abstract

The invention discloses an injection molding die and method of an automotive engine intake manifold. An inverted-buckling component provided with inverted buckling is formed on the intake manifold in the die opening direction of a forming die of the intake manifold, and the forming die comprises a front die body and a rear die body. The front die body and the rear die body are combined together to form a die cavity of the intake manifold. The forming die further comprises a front die ejection rod mechanism arranged on the front die body and used for abutting against the intake manifold to press the intake manifold onto the rear die body when die opening of the forming die is conducted. The inverted-buckling face of the inverted-buckling component and the die opening direction of the forming die form an angle ranging from 0 degree to 60 degrees. The forming die further comprises an intake manifold ejection mechanism which is arranged on the rear die body and used for ejecting the intake manifold out of the rear die body in the direction perpendicular to the inverted-buckling face of the inverted-buckling component. By means of the injection molding die and method of the automotive engine intake manifold, the production cost is lowered, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of forming molds, in particular, the invention relates to an injection molding mold and method for an automobile engine intake manifold; the automobile engine intake manifold is generally a plastic product, and is a hollow product with a complex shape and structure. Background technique [0002] In the automobile industry, the intake manifold of the automobile engine is one of the most important components in the intake system of the automobile engine. It determines the intake efficiency of the engine and the uniformity of the air charge of each cylinder, and has a great impact on the performance of the whole machine. The traditional automobile engine intake manifold is produced by casting iron or aluminum alloy, which has obvious disadvantages such as rough surface, large inflation resistance, and heavy product. In order to reduce weight, reduce fuel consumption, improve automobile engine performance and reduce emiss...
