Abstract

The invention provides a mold core structure of a micro-foaming injection mold. The mold core structure comprises a mold core body and a sub-mold core, wherein one side of the mold core body is provided with one side groove; a clamping device and a top plate are arranged in the side groove; the clamping device comprises a base, a clamping piece body, a sliding base and a screw rod; the clamping piece body is fixedly arranged on the upper surface of the base; a fixing base is fixed on the base; a connecting base is fixed on the upper surface of the base; one end of the screw rod is movably arranged on the fixing base; and the other end of the screw rod is movably arranged on a connecting base. According to the mold core structure of the micro-foaming injection mold, the mold core body is detachably connected with the sub-mold core, and the clamping device is arranged in the side groove of the mold core body, so that only the sub-mold core needs to be replaced, the replacement is more convenient, and the sub-mold core can be tightened during installing.

Description

technical field [0001] The invention relates to mold parts, in particular to a core structure of a microfoaming injection mold. Background technique [0002] In the manufacture of micro-foaming injection molds, the matching template structure of the mold and the mold core structure of the mold are prepared and processed separately, that is, the mounting holes for positioning are processed on the mold core first, and then the processed inserts are combined with The templates cooperate with each other to form the overall structure of the mold. In actual production, the mold core can bring different benefits, but the mold core structure is relatively single, and this kind of mold core wastes more mold core materials during the production process, especially only the mold core needs to be replaced, other parts When there is no need to replace, the replacement of the entire mold core is a waste. [0003] For this reason, how to improve the structure of the mold core, realize ba...
