Problems solved by technology

If it is not cleaned, the powder will easily stick to the follow-up water channel when the subsequent coolant is introduced, burying hidden dangers for subsequent use
The existing cleaning methods are generally impacted by the compressed air of the atmospheric airflow, so as to realize the powder removal, but due to the complex structure of the conformal water channel and the existence of coils, the powder is easily crushed under the impact of the compressed air of the atmospheric airflow. The inner wall of the waterway has a mechanical bite, which directly forms a blockage. In severe cases, it may even cause the mold to be scrapped

Abstract

The invention relates to a 3D printing anti-grafting molding method of a mold for injection molding. The specific molding steps are as follows: 1) Mold end molding: the mold end is processed and formed by mold steel, and the end of the mold steel is processed into a corresponding shape according to the shape of the product. shape, and process the bottom of the mold steel into the same shape as the end of the mold steel, and process the end of the mold into a sheet shape that adapts to the shape of the product; Made of the best metal material or alloy material, the cooling conduction pad is embedded in the bottom of the mold steel, and the bottom of the cooling conduction pad is processed into a plane shape; 3) Mold core forming: the inside of the mold core is provided with The conformal waterway, the mold core and the conformal waterway are processed by 3D printing. The invention can shorten the time-consuming and cost of 3D printing molding, and can ensure the flatness of the injection end surface of the mold, and can effectively remove residual powder.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing for injection molding, in particular to a method for making a mold for injection molding by 3D printing reverse grafting. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Since the injection mold needs to have a cooling effect during injection molding production, the existing injection mold itself is generally provided with corresponding cooling water channels distributed through machining. Since the shapes of many injection molded products are irregular curved surfaces, for example, the top cover of the mouse is in the shape of an upward convex arc, which requires the contact surface between the injection mold and the injection molding material to have an irregular shape. Most of the cooling water channels formed by machining are straight lines, which are ...
