Pneumatic recoil type stamping die and using method thereof

Abstract

The invention relates to the technical field of dies, in particular to a pneumatic recoil type stamping die. The pneumatic recoil type stamping die comprises a base, wherein the top of the base is fixedly connected with a fixing table through a supporting plate, the top of the fixing table is fixedly connected with a hydraulic telescopic air cylinder, the free end of the hydraulic telescopic air cylinder is fixedly connected with a connecting rod, the bottom end of the connecting rod penetrates through the fixing table and extends to the position below the fixing table, the top of the base is fixedly connected with a lower die sleeve, and the bottom end of the connecting rod is fixedly connected with a lower die sleeve. According to the pneumatic recoil type stamping die, by arranging an air pressure cavity, after injection molding is completed, air in the air pressure cavity is injected into a hydraulic cavity and an annular air bag, in this way, heat exchange liquid and cooling oil can be made to be close to a molded product, the product can be rapidly cooled, the molding time is shortened, the molding efficiency is improved, after molding is completed, in the separation process of an upper die sleeve and the lower die sleeve, air pressure can cool and shape a product, the product can be ejected out of the die cavity through air pressure recoil force after shaping, the whole process is high in continuity, and no manual intervention is needed.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a pneumatic recoil stamping die and its usage method. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] The clamping mold consists of an upper mold, a lower mold, a mold cavity and a mold core. This type of mold injects slurry water after the mold is closed. The slurry water is formed in the mold cavity and can be demoulded after a certain period of cooling. However, during th...
