Injection molding machine nozzle and mold entry point anti-blocking device for plastic pipe fittings production

Abstract

The invention relates to the technical field of plastic pipes, in particular to an injection molding machine nozzle and a mold entry point anti-blocking device for the production of plastic pipe fittings. The technical problem to be solved by the present invention is that the filter tank of the comparison case is easy to cause impurities to accumulate after being used for a period of time. In order to solve the above-mentioned technical problems, the present invention provides an injection molding machine nozzle and mold entry point anti-blocking device for the production of plastic pipe fittings. The outer side of the left side of the main column is fixedly connected with a bottom plate at equal intervals, a blocking column is fixedly connected between the top plate and the bottom plate, a filter column is fixedly connected between the top plate and the bottom plate, and filter columns are arranged at equal intervals in the middle of the filter column. The outer side of the main column is equally spaced with feeding grooves, the outer side of the main column is equally spaced with discharge grooves, the right side of the main column is fixedly connected with a filter spring, and the right side of the filter spring The fixed connection has a pressure plate.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to an injection molding machine nozzle and a mold entry point anti-blocking device for the production of plastic pipe fittings. Background technique [0002] The working principle of the hot runner injection mold in the prior art is as follows: the molten plastic raw material is added into the material tube of the injection molding machine from the hopper of the injection molding machine, and the molten plastic raw material is pushed into the heat flow of the mold under the push action of the screw or plunger of the injection molding machine. Enter the closed mold cavity in the channel system. For example, Chinese patent 2012102751985 discloses an injection molding machine nozzle and a mold entry point anti-blocking device. The rear part is equipped with a filter column. The filter column has a feed tank, a discharge tank and a filter tank. The raw material enters the filter c...
