Die-casting die and die-casting device

Abstract

The invention relates to a die-casting die and a die-casting device. The die-casting die comprises a die core and a cooling water channel insert, a spiral structure is arranged on the outer surface of the cooling water channel insert and comprises a spiral groove, a blind hole is formed in the center of the die core and used for mounting the cooling water channel insert, the inner wall of the blind hole and the groove formed in the outer surface of the cooling water channel insert form a spiral pipeline, one end of the cooling water channel insert is provided with a water inlet and a water outlet, and the water inlet and the water outlet are communicated with the spiral pipeline to form a cooling water circulation loop.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold and die-casting equipment. Background technique [0002] In the existing motor shell products, the inner cavity of the molded motor shell needs to adopt a protruding cylindrical structure. Since it is a protruding structure, the setting of the cooling water circuit of this structure is very important. [0003] Such as figure 1 and figure 2 As shown, the cooling of the existing mold generally adopts the form of "water well", and the deep hole 10 is processed and cooperates with the water barrier 20 to form a circulating water channel. Therefore, there are two following problems in the cooling water path of the existing mold: one is to drill holes on the mold structure to make the cooling water path, and stress concentration will be formed in the processing area. The more holes are processed, the greater the impact on the matrix of the material, whic...

Problems solved by technology

[0005] In order to improve the deficiencies of the prior art, the purpose of the present invention is to provide a die-casting mold and die-casting equipment to solve the problems existing in the prior art by punching holes on the existing mold structure to make cooling water channels, and that stress concentration will be formed in the processing area. The more processing holes, the greater the impact on the material matrix, and the more prone to cracking the mold structure after processing, and because the inner bore size of the product is not processed, the mold size needs to be monitored very strictly, and the replacement of spare parts can hardly be guaranteed after replacement. Qualified castings are produced immediately, and generally need to be repaired again before they can be used, causing difficulties in the production of the workshop; and due to the distribution of the waterway, the temperature distribution of the slider core will be uneven.
