[0003] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. A mold in which the product is molded by die casting, so that molten metal is filled into the mold cavity under a certain pressure and solidified and molded while maintaining the pressure to be processed into parts. The casting mold of the traditional light alloy motor casing, its The addition method of molten metal is too simple to realize a flexible and controllable liquid injection process, and the speed of condensation of molten metal in traditional casting molds in the mold cavity is slow and the work efficiency is low. Therefore, it is necessary to propose a light alloy motor casing with low pressure casting mold

The invention relates to the technical field of mold manufacturing and particularly discloses a low-pressure casting mold of a light alloy motor shell. The low-pressure casting mold of the light alloy motor shell comprises a male mold and a female mold. The male mold and the female mold are combined to form a mold cavity. The upper surface of the male mold is provided with an annular material supply groove. A base plate of the annular material supply groove is symmetrically provided with two material filling holes communicating with the mold cavity. The upper surface of the female mold is fixedly provided with a material box. The bottom of the material box is provided with a rotating material supply portion. The rotating material supply portion comprises a rotating disk which is rotationally arranged in the lower inner cavity of the material box in a sealed manner. The bottom face of the rotating disk is provided with an annular material supply block which is sliding fit with the annular material supply groove. Two material feeding holes are symmetrically formed in the annular material supply block in a penetrated manner. The low-pressure casting mold of the light alloy motor shell achieves that under the condition that visual watching cannot be realized, whether a liquid feeding channel is in communication or not can be accurately judged, so that casting liquid can be poured into the mold cavity.
Description
technical field [0001] The invention relates to the technical field of mold equipment, in particular to a low-pressure casting mold for a light alloy motor casing. Background technique [0002] Low-pressure casting is a casting method in which liquid alloy is pressed into the mold cavity from bottom to top under pressure, and solidified under pressure to obtain castings. [0003] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. A mold in which the product is molded by die casting, so that molten metal is filled into the mold cavity under a certain pressure and solidified and molded while maintaining the pressure to be processed into parts. The casting mold of the traditional light alloy motor casing, its The addition method of molten metal is too simple to realize a flexible and controllable liquid injection process, and the speed of condensation of molten metal i...
