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] As shown in Fig. 1 and Fig. 2, the injection nozzle with filtering device has a nozzle nozzle base 1 connected with the barrel of the main engine, 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 feeding ...

Abstract

The invention discloses an injection nozzle with a filtering device, which has a nozzle tube base which is connected with a host material barrel, an injection passage is provided in the nozzle tube base, a filtering device is arranged in the nozzle tube base, the front end outer edge of the filtering device and the passage in the nozzle tube base are cooperated sealing, the outer diameter of the middle part of the filtering device is smaller than that of the front outer edge of the filtering device, a filtering gas is formed between the nozzle tube base and the filtering device, the outer size wall at the middle part of the filtering device is provided with a plurality of feeding grooves and discharging grooves which are arranged in interval, the material flow passes through the filtering device, which can filter off the impurity in the material, also can make the color of the product of color material 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...
