Injection mold convenient for stable demoulding

Abstract

The invention discloses an injection mold convenient for stable demoulding. The injection mold comprises a moving module and a fixed module, the moving module comprises a moving base, a supporting plate is welded to the moving base, a cavity is formed between the moving base and the supporting plate, an air pump is installed in the moving base, an air bag is connected to the output end of the airpump, a pressing plate is fixedly adhered to the air bag, two abutting rods are correspondingly welded to the pressing plate, springs are arranged on the two abutting rods in a sleeving mode, a sliding groove is formed in the inner wall of the cavity, and sliding blocks are correspondingly welded to the upper end and the lower end of the pressing plate. According to the injection mold, a water-cooling cavity is utilized to improve the cooling setting efficiency of a plastic part, and thus the waiting time of demoulding is shortened; the temperature in the injection mold is adjusted properly through the cooling effect, the temperature difference between the injection mold and the environment is advantageously reduced, and thus the air pressure adjustment in an injection module is achieved;and the air pump is utilized to inflate the air bag to achieve the horizontal movement of the abutting rods, thus the abutting rods push the forming plastic part, and the plastic part is separated from a moving mold stably.

Description

technical field [0001] The invention relates to the technical field of injection molding processing of plastic parts, in particular to an injection mold which is convenient for stable demolding. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some parts with complex shapes. It refers to injecting the heated and melted plastic slurry into the molding groove from the injection molding machine under high pressure, and after cooling and solidifying, a molded product is obtained. [0003] In the existing injection molding process and mold use, after the injection slurry enters the molding tank, because of the lack of corresponding cooling measures, it takes a long time to wait for the injection slurry to cool down and form, and the temperature of the slurry can be 200°C, the eff...
