Description

Cooling system for POM transmission part injection mold Technical Field The utility model relates to the technical field of injection mold sorting, in particular to a cooling system for a POM transmission part injection mold. Background Polyoxymethylene (POM) is widely used as a high-performance engineering plastic for manufacturing transmission members such as gears, bearings, etc., due to its excellent mechanical strength, wear resistance and self-lubricity. Injection molding is the main processing mode of the POM transmission piece, and the molding quality is directly affected by the temperature control of the mold. Through searching, the utility model with the Chinese patent publication number of CN207859422U discloses a cooling system of an injection mold, which comprises a positioning ring, a front cover plate and an upper template, wherein the positioning ring is positioned at the upper part of the front cover plate, the upper template is positioned below the front cover plate, a cooling water inlet of the upper template is arranged at one end of the upper template, a cooling water outlet of the upper template is arranged at the other end of the upper template, a flow guide pipe is arranged in the upper template and the lower template, and a cooling upright post is connected with the outer wall of the flow guide pipe in a penetrating mode. The cooling of mould is realized through the cooling stand to above-mentioned device, and its cooling principle is to the material of periphery cooling first, however just can absorb the heat of product to be close to the area of product less, the cooling needs to consume longer time, exists the improvement space. Disclosure of utility model The utility model aims to provide a cooling system for a POM transmission part injection mold, which is used for solving the problems in the background art. The cooling system for the POM transmission part injection mold comprises a mold body, wherein a through groove is formed in the mold body, the through groove is positioned at the bottom of a molding cavity of the mold body, a mounting plate is inserted in the through groove in a sliding mode, a mounting groove is formed in the outer wall of the top of the mounting plate, a cooling assembly is mounted in the mounting groove, the cooling assembly comprises a plurality of cooling pipes placed in the mounting groove, two ends of each cooling pipe are fixedly sleeved with a connector, a plurality of springs are fixedly connected to the inner wall of the bottom of the mounting groove, one end of the top of each spring is fixedly connected with one mounting ring, and the mounting rings are fixedly connected to the outer walls of the bottoms of the cooling pipes. Guarantee that cooling tube and mould body take shape die cavity area is big enough to make driving medium heat can be by faster absorption, be favorable to improving cooling efficiency, apply the pressure to the connector that is close to blocking the post, the pressure is applyed on the spring through cooling tube and collar, the spring atress is compressed, a plurality of cooling tubes will get into the mounting groove inside, peg graft mounting panel one end to running through in the groove, stop grafting operation when butt plate and mould body outer wall laminating, because the cooling tube can't move up under the restriction of running through the groove, the spring keeps compression state, and extrude the cooling tube and run through the groove roof through the collar, thereby guarantee that heat can be directly absorbed.
