Problems solved by technology

Ordinary nozzles mostly have a one-stage structure and the nozzle itself does not have a heating function, but the heat will always be lost during the process of the raw material flow into the mold
Therefore, after the product is formed, it is easy to produce defects such as cold material marks and white spots.
Moreover, the raw materials in the current plastic production are usually a mixture of several raw materials, but the melting points of various raw materials are different, and it is easy to block the nozzle during the continuous temperature change.
The trouble is, after clogging, the entire nozzle needs to be unscrewed from the injection molding machine with a wrench, which is time-consuming, laborious and inefficient

Abstract

The invention discloses a nozzle for an injection molding machine and relates to the field of injection molding machines. The nozzle for the injection molding machine comprises a primary nozzle and a secondary nozzle; both the primary nozzle and the second nozzle are provided with runners and are communicated with each other; the primary nozzle is provided with a first connection end; the secondary nozzle is provided with a second connection end; the primary nozzle is connected with the secondary nozzle; the joint position of the primary nozzle and the secondary nozzle is provided with a filter screen; and the secondary nozzle is provided with a spiral heating wire. According to the nozzle for the injection molding machine, arrangement of the heating wire enables the nozzle for the injection molding machine to be difficult to block; and by arrangement of the filter screen, impurities in raw materials can be effectively filtered, the nozzle is prevented from being blocked, and in case of blockage, blockage can be cleared away after the primary nozzle is disassembled.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a nozzle of an injection molding machine. Background technique [0002] The nozzle of the injection molding machine is an important connecting part for the injection molding machine to complete the injection molding of the mold. Ordinary nozzles mostly have a one-stage structure and the nozzle itself does not have a heating function, but the heat will always be lost during the process of the raw material flow into the mold. Therefore, after the product is formed, it is easy to produce defects such as cold material marks and white spots. Moreover, the raw materials in the current plastic production are usually a mixture of several raw materials, but the melting points of various raw materials are different, and it is easy to block the nozzle during the continuous temperature change. The trouble is, after clogging, the entire nozzle needs to be unscrewed from the injecti...
