Problems solved by technology

[0002] Injection molding, also known as injection molding, is a molding method of injection and molding. During the injection molding process of injection molded parts, since the injected fluid is in a high-temperature molten state, and the mold is usually at room temperature, when the high-temperature molten fluid After entering the mold, part of the fluid will solidify rapidly due to the relatively low temperature of the mold, so that the uneven filling of the fluid in the mold cavity will affect the molding of the injection molded part. Therefore, we have designed an injection mold with thermal compensation function to solve the above problems

Abstract

The invention discloses an injection mold with thermal compensation function, which comprises an upper mold and a lower mold. The upper mold and the lower mold are provided with matching upper mold modules and mold grooves, and the bottom of the lower mold is longitudinally penetrated. There is a mounting groove, and a mounting plate is fixedly connected to the mounting groove, and a thermal compensation oil tank and a cooling oil tank are installed on the mounting plate, and a heating device and a refrigeration device are respectively installed in the thermal compensation oil tank and the cooling oil tank. A first water pump and a second water pump are respectively installed on the compensation oil tank and the cooling oil tank, and the water inlet ends of the first water pump and the second water pump communicate with the thermal compensation oil tank and the cooling oil tank respectively. Cavity matching cavity. The invention has a reasonable structure, can automatically heat the upper mold and the lower mold, make the high-temperature molten fluid enter the mold cavity and fill it evenly, improve the quality of injection molded parts, and can realize automatic cooling of the mold cavity, which is convenient for molding and demolding .

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with thermal compensation function. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. During the injection molding process of injection molded parts, since the injected fluid is in a high-temperature molten state, and the mold is usually at room temperature, when the high-temperature molten fluid After entering the mold, part of the fluid will solidify rapidly due to the relatively low temperature of the mold, so that the fluid will be filled unevenly in the mold cavity, which will affect the molding of the injection molded part. Therefore, we have designed an injection mold with thermal compensation function to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an injec...
