Mold cooling system of injection molding machine

Abstract

The invention discloses a mold cooling system of an injection molding machine. The mold cooling system comprises an injection molding machine body. The injection molding machine body comprises a protective cover and a mold pushing rod. The mold pushing rod penetrates through the protective cover. A mold lower mold is arranged in the protective cover and fixedly connected with the mold pushing rod.The side wall of the upper end of the mold pushing rod is fixedly connected with a vertically-arranged L-shaped blocking rod. The side wall of the upper end, away from the protective cover, of the mold pushing rod is fixedly connected with a supporting rod, and the side wall of the upper end of the supporting rod is fixedly connected with a water tank. A water pipe is arranged on the side wall, close to the protective cover, of the water tank in a communicating mode, and penetrates through the protective cover. The side wall of the upper end of the water pipe is rotationally connected with abaffle through a rotating shaft, and the baffle is located between the water tank and the L-shaped blocking rod. According to the mold cooling system, cooling liquid is directly sprayed on the surfaceof a mold cavity of a mold, so that the mold keeps the low temperature when working in the injection molding machine, and the mold is prevented from overheating.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a mold cooling system of an injection molding machine. Background technique [0002] Injection molding machine is also called injection molding machine. It injects thermoplastic materials or thermosetting materials into molds after high temperature heating to make plastic products of various shapes. The injection molding machine includes a heating system and a cooling system. The heating system is used for heating. The cooling system of the barrel and injection nozzle is mainly used to cool the oil temperature and prevent the mold temperature from being too high. [0003] In the prior art, when the mold is used on the injection molding machine for a long time, the temperature of the mold will be very high, and the oil temperature cooling system of the injection molding machine alone cannot reduce the temperature of the mold, and sometimes the temperature of the...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when the mold is used on the injection molding machine for a long time, the temperature of the mold will be very high, and the oil temperature cooling system of the injection molding machine alone cannot reduce the temperature of the mold, and sometimes it will cause The mold temperature is too high, so that the molten material cannot be cooled and formed, causing problems such as product surface depressions, and a mold cooling system for injection molding machines is proposed
