Abstract

The invention discloses a conformal cooling waterway mold structure and a processing method, relates to the technical field of mold manufacturing, and solves the problems that the conventional 3D printed conformal cooling waterway mold has high cost, and the print size is limited. According to the technical scheme, the conformal cooling waterway mold structure comprises a basal body and an insert, wherein a groove is formed in the molding surface of the basal body, and at least two waterways communicated with the groove are arranged in the basal body; the insert is mounted in the groove, and conformal waterways are arranged on the two sides of the contact surface of the insert and the basal body or in the insert and communicated with the waterways in the basal body to form channels; a cladding layer is arranged at the seam line of the insert and the basal body, and the external surface of the cladding layer is the molding surface. The conformal cooling waterway mold structure is detachably processed, and the insert can be processed in the conventional mechanical processing way or the selective laser melting 3D printing processing way. The liquid and gas sealing in the waterways is ensured, the processing and manufacturing cost is significantly reduced, and the popularization and application of the conformal cooling waterway is facilitated.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a conformal cooling water channel mold structure and processing method. Background technique [0002] 3D printing technology has been applied to the mold processing of the conformal cooling channel of the injection mold. The conformal cooling channel is mainly set in the core and cavity of the product molding to shorten the cooling cycle, make the temperature field of the injection molded product uniform, and reduce the Warpage and sink marks of product parts caused by uneven heating and cooling can ensure the quality of product parts and improve the economic benefits of enterprises. [0003] However, at present, the cost of injection molds for processing conformal cooling channels using 3D printing technology is quite high, and the single-piece processing cost of injection molded parts reduced by shortening the cooling time is limited. Generally, more than hundreds of...
