Embodiment 1

[0014] A cooler for the discharge port of an injection molding machine, which is composed of a heat exchange shell 3 and a cooling pipe 2 installed in the heat exchange shell. The cooling pipe 2 is a stretchable stainless steel bellows, and the inner wall of the heat exchange shell 3 is made of material grade Made of A360 aluminum alloy, the heat exchange shell 3 is an open circular ring with fastening screw holes 4 and a gap width of 1-5 cm. The cooling pipe 2 is equipped with a water inlet and outlet 1 .

[0015] After the injection molding head of the heating screw enters, tighten it with screws through the fastening screw hole 4 at the opening, and hold the heating screw, so that the heating screw quickly dissipates heat through the inner wall made of heat-conducting material to achieve cooling; The water is circulated and cooled, and it can work under the pressure of 5Pa per minute and the water flow rate of 80mm.

Abstract

The invention relates to a discharge opening cooler of an injection molding machine, which consists of a heat exchange shell (3) and a cooling tube (2) arranged in the heat exchange shell, wherein the heat exchange shell (3) is in an open annular shape; the inner wall of the heat exchange shell (3) is made of heat conductive material; the opening part of the inner wall is provided with a fastening screw hole (4); and the cooling tube (2) is provided with a water inlet and outlet opening (1). The cooler adopts water circulation cooling to reduce the temperature of a hot charging barrel screw, protect the charging barrel screw against wear and improve the service life of the charging barrel screw. The product reduces the temperature to 80 to 90 DEG C, ensures the smooth passing of plastic granules for injection, solves the granule blockage problem, improves overall production efficiency, and improves the performance of the injection molding machine.

Description

technical field [0001] The invention belongs to the field of processing parts of injection molding machines, and in particular relates to cooling equipment for injection molding machines. Background technique [0002] When the injection molding machine is working, the temperature of the feeding barrel will continue to rise, which will not only make it difficult for plastic particles to pass through the injection molding smoothly, but also reduce the service life of the screw. Because there is no special equipment for the feeding barrel of the existing injection molding machine, the working temperature is usually kept at 160°C to 190°C. This high temperature will seriously affect the working efficiency. Even when the raw material is nylon material, the feed port will be clogged and blocked. It will waste dredging time and affect normal production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coole...
