Description

Novel glue injection mold

Technical Field

The utility model belongs to the technical field of the injecting glue mould, specifically relate to a novel injecting glue mould.

Background

The screw pump works by the rotation of the mutually meshed screws, and in the rotation process of the screws, materials generate certain friction with the screws and the inner wall of the pump body, so that the working surfaces among the screws, the inner wall of the pump body and the screws are gradually abraded, the diameters of the screws are gradually reduced, and the diameters of inner holes of the pump body are gradually increased. Therefore, the gaps between the screw and between the screw and the inner wall of the pump body are slightly enlarged along with the gradual abrasion of the screw and the screw, so that the leakage flow of the transported materials is increased when the transported materials move forward, and meanwhile, when the screw pump transports liquid with high impurity content, the screw is easily blocked by some hard impurities, so that the working efficiency is reduced. Therefore, it is important to develop a new screw pump to improve the abrasion resistance of the screw, the sealing performance of the screw and the medium passing capacity. The wear-resisting property of the screw pump can be improved to a certain extent by lining the rubber on the screw, however, when the screw is coated with the rubber by using the traditional rubber injection mold, the condition of uneven or incomplete rubber lining often occurs, so that the screw lined with the rubber cannot meet the use requirement.
