Combined mold for producing ink box in copying machine

Abstract

The invention belongs to the technical field of molds, and discloses a combined mold for producing an ink box in a copying machine. The combined mold comprises a base, a first mold and a second mold are mounted at the top end of the base, the first mold comprises a first lower mold and a first upper mold, the first upper mold is mounted above the first lower mold, the second mold comprises a second lower mold and a second upper mold, the second upper mold is installed above the second lower mold, and a supporting block is fixed to the side, facing the second upper mold, of the first upper mold. According to the combined mold, a first annular groove, a first spiral heat exchange pipe, a second annular groove and a second spiral heat exchange pipe are matched, two mold cores are externally wound with the heat exchange pipes which are in through connection correspondingly, the heat exchange area can be effectively increased, after injection molding, cooling liquid is introduced into the heat exchange pipes, the cooling forming speed of molten raw materials can be effectively increased, in addition, the two molds adopt a low-in high-out heat exchange mode, and the heat exchange effect is better.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a combined mold for producing ink cartridges in copiers. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products. In short, molds are tools used to make shaped objects , this kind of tool is composed of various parts, and different molds are composed of different parts. The copier is a device that uses electrostatic technology to copy documents. The copier is an analog method and can only faithfully copy documents. An integral part of the ink cartridge production process, usually using injection mold injection molding. [0003] However, there are certain defects in the existing molds for ink cartridge production at present. The combined injection mold for traditional ink cartridge production has ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a combination mold for the production of ink cartridges in copiers, to solve the problems in the above-mentioned background technology that the traditional combination injection mold for ink cartridge production has poor heat dissipation effect and the cooling and molding speed of the sample is relatively slow. In addition, the upper and lower molds The limit effect during installation is poor, and the installation of the upper and lower molds is prone to misalignment.
