Problems solved by technology

[0003] After the mold is formed, when the mold needs to be opened, the side core needs to be pulled out first. Because the mouth of the shampoo bottle cap is in the shape of a curved tube, it cannot be pulled out by using the existing straight core when pulling the core. It must be designed accordingly. Easy to pull out and open the mold

Abstract

The invention provides an elbow pipe core pulling mechanism of a shampoo bottle cap. The elbow pipe core pulling mechanism of the shampoo bottle cap is characterized in that a mold comprises a mold casting assembly, a mold fixed mold assembly, a mold movable mold assembly, a mold forming part, a mold ejection mechanism and a mold core pulling mechanism, the mold is provided with eight cavities, acasting system adopts a cold runner pin point gate pouring system, and the mold is designed aiming at the inconvenient core pulling condition at an elbow pipe of the shampoo bottle cap, so that quickelbow core pulling of a product is achieved, moreover, the structure is simple, the production and manufacturing cost of the mold is effectively reduced, and the production and manufacturing period ofthe mold is shortened.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to an elbow core-pulling mechanism of a shampoo bottle cap. Background technique [0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to melting plastic by heat. The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the molded product is obtained. [0003] After the mold is formed, when the mold needs to be opened, the side core needs to be pulled out first. Because the mouth of the shampoo bottle cap is in the shape of a curved tube, it cannot be pulled out by using the existing straight core when pulling the core. It must be designed accordingly. Easy to pull out and open t...
