Processing method of hot forming conformal waterway mould

Abstract

The invention discloses a processing method of a hot forming conformal waterway mould. The method comprises the steps that 1, a base body of a hot forming conformal waterway mould is cast by adoptinga casting technology, and the surface of the base body is subjected to finish machining to form a supporting surface corresponding to a molded surface of the mould; 2, a cooling insert with a conformal waterway is printed on the supporting surface of the base body by adopting 3D printing equipment; 3, finish machining is carried out on the printed cooling insert. The hot forming conformal waterwaymould is integrally formed by the base body and the cooling insert, and inserts do not need to be spliced. The conformal waterway is formed in the cooling insert, so that water leakage is avoided. The molded surface of the mould is free of splicing seams, so that the quality of the molded surface of the mould is high. In the method, only the cooling insert is formed through the 3D printing technology so that the consumption of printing materials can be greatly reduced, 3D printing time is shortened, and the production efficiency is improved. Meanwhile, the method has the advantages of being high in cooling efficiency and good in molded surface temperature uniformity.

Description

technical field [0001] The invention relates to the field of thermoforming moulds, in particular to a processing method for thermoforming conformal waterway moulds. Background technique [0002] Such as figure 1 As shown, limited by the traditional manufacturing process, thermoforming molds for auto parts are spliced ​​sequentially by multiple mold inserts 1 with straight-through water channels inside, and sealed by bolts and sealing rings. This mold insert with straight-through water channels Due to the aging of the sealing ring and the deviation of the bolt size, etc., water leakage is easy to occur, and the water leakage is difficult to detect. And because of splicing errors, there will be tiny gaps on the mold surface at the splicing place. Contents of the invention [0003] The invention provides a processing method for thermoforming conformal waterway molds to solve the above-mentioned technical problems existing in the prior art. [0004] In order to solve the ab...
