Problems solved by technology

[0002] At present, for the nozzle used on the injection molding machine, one end of the nozzle is connected to the barrel on the main machine, and the nozzle of the other end is matched with the mold. There are inevitably some impurities in the raw materials used in production. The original structure of the nozzle is If there is no filter device, the raw material flow is directly injected from the barrel through the nozzle into the mold, so the impurities cannot be filtered out, and the quality of the product cannot be well controlled

Embodiment Construction

[0010] Such as figure 1 , figure 2 As shown, the injection nozzle with a filter device has a nozzle nozzle base 1 connected to the barrel of the main machine, an injection channel 11 is provided in the nozzle nozzle holder, and a filter device 2 is built in the nozzle nozzle holder 1 . The rear part 21 of the filter device 2 is threadedly connected and fixed to the nozzle socket 1, wherein the outer edge 22 of the front end of the filter device 2 and the inner channel 11 of the nozzle socket 1 are sealed and fitted, and the outer diameter of the middle part 23 of the filter device 2 is smaller than that of the filter device. 2 The outer diameter of the outer edge 22 of the front end, thus forming a filter gap 3 between the nozzle socket 1 and the filter device 2, and a plurality of feed grooves 24 and discharge grooves 25 are arranged on the outer wall of the middle part 23 of the filter device , Feed chute 24 and discharge chute 25 are arranged at intervals. A plurality of...

Abstract

The invention discloses an injection nozzle with a filtering device. The injection nozzle has a nozzle header connected with a host barrel, an injection passage provided in the nozzle header, and a filter in the nozzle header. The front outer edge of the filter and the passage in the nozzle header are sealed fit, the outer diameter of the middle part of the filter is smaller than the outer diameter of the front outer edge of the filter; a filtering gap is formed between the nozzle header and the filter, the outer side wall at the middle part of the filter is provided with a plurality of feeding grooves and discharging grooves arranged at intervals, when the material flow passes through the filter, the impurity in the material can be filtered off and the colors of any product from color material can be more even.

Description

technical field [0001] The invention relates to a nozzle used in conjunction with an injection molding machine. Background technique [0002] At present, for the nozzle used on the injection molding machine, one end of the nozzle is connected to the barrel on the main machine, and the nozzle of the other end is matched with the mold. There are inevitably some impurities in the raw materials used in production. The original structure of the nozzle is If there is no filter device, the raw material flow is directly injected from the barrel through the nozzle into the mold, so the impurities cannot be filtered out, and the quality of the product cannot be well controlled. Contents of the invention [0003] In view of the defects of the above technical solutions, the object of the present invention is to provide an injection nozzle with a filtering device, which can filter out impurities in the raw materials, and can also make the product color of the colored raw materials more...
