Water-cooling sprue bush for die casting

Abstract

The water-cooling sprue bush comprises a sprue bush body, a cooling pipe and a connecting sleeve, one end of the sprue bush body is fixedly connected with a sealing cover through a bolt, a limiting groove is formed in one end of the sprue bush body, the cooling pipe is installed in the limiting groove, and a connecting plate is installed at the other end of the sprue bush body; the other end of the sprue bush body is connected with a connecting sleeve through a connecting plate, and a threaded rod is installed on the outer wall of the connecting sleeve in a penetrating mode. Cooling water can be conveyed into the water inlet pipe through the water inlet pipe, the cooling water flows in the water pipe, so that the cooling pipe can cool the sprue bush main body, and the sprue bush main body can be well cooled through communication of the water pipes; and the sprue bush main body is prevented from being damaged due to over-high temperature after long-time use.

Description

technical field [0001] The invention relates to the technical field of sprue sleeves, in particular to a water-cooled sprue sleeve for die casting. Background technique [0002] The casting system of the die-casting mold consists of a gate sleeve, a runner and a gate. During the pouring process, the molten metal enters the mold cavity directly through the gate sleeve, the runner and the gate. The sprue sleeve is a component of the runner that allows the molten plastic material to be injected from the nozzle of the injection molding machine into the mold. It is used to connect the molding mold and the metal parts of the injection molding machine. During the die-casting operation, the temperature of the sprue sleeve controls the quality of the casting. have no small impact. [0003] The disadvantages of the sprue sleeve in the prior art are insufficient: [0004] 1. In the prior art, the cooling effect of the sprue sleeve is not good, and it cannot have a good cooling effect...

AI Technical Summary

Problems solved by technology

[0004] 1. The cooling effect of the sprue bushing in the prior art is not good, and it cannot have a good cooling effect on the sprue bushing. After a long time of use, the sprue bushing will be damaged due to excessive temperature, which is not convenient for the staff use;

[0005] 2. In the prior art, the sprue sleeve is not stable in use, cannot be fixed well, and it is not convenient for the staff to disassemble and repair when it is damaged, thereby reducing the work efficiency of the staff
