Abstract

The invention discloses an injection molding machine nozzle with a self-cleaning function. The injection molding machine nozzle comprises a nozzle body and a piston, a piston is arranged inside the nozzle body, and a conical plug is welded to one end of the piston, and the other end of the conical plug is connected with an inserting block in a welded mode. According to the maching nozzle, the conical plug and the piston are located inside the nozzle body, the size of the piston is equal to the internal size of the nozzle body, a remaining injection molding material inside the nozzle body can be pushed out of the nozzle body in a forward propelling process of the piston, the effect of scraping residual materials inside the nozzle body is achieved, and a self-cleaning function of the nozzlebody is enabled to be finished; the size of the conical plug is equal to the internal size of one end of the nozzle body, when the piston is conveyed to an end part, the conical plug is attached to the inner wall of one end of the nozzle body, the materials inside the nozzle body can be completely extruded out, so that no material is left in the nozzle body, blockage is avoided, the workload of manual cleaning of the nozzle is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machine nozzles, in particular to an injection molding machine nozzle with a built-in cleaning function. Background technique [0002] In modern life, the plastic products we use in our daily life, such as toys, control panels of household appliances and other plastic products, are usually formed by injection molding machines and molded with specific shapes. [0003] Most of the nozzles of injection molding machines at the present stage use needle-type shut-off nozzles. Although this nozzle can prevent material leakage, its structure is complex, difficult to clean, and it is easy to cause clogging. At the same time, the internal spring is prone to elastic attenuation. If it is not cleaned in time after injection molding, it will also cause blockage, which will bring inconvenience to the follow-up work. In view of the above problems, a nozzle of injection molding machine with self-cleanin...
