3D printing integrated structure exhaust insert mold core method and exhaust insert mold core

Abstract

The invention discloses a method for 3D printing the core of an exhaust insert with an integrated structure, which comprises the following steps: (1) establishing a three-dimensional modeling model of the mold core and the exhaust insert with an integrated structure through CAD auxiliary software, and the exhaust insert (2) The 3D modeling model is processed by CAD modeling and layered slicing software to obtain the data of each layer required by the 3D printer for the mold core and exhaust inserts. The data of each layer includes the mold core The laser sintering area and the exhaust insert laser sintering area; import the data of each layer into the 3D printer, and set the scanning parameters of the mold core laser sintering area and the exhaust insert laser sintering area in the 3D printer; (3) according to The laser scans the data of each layer to scan layer by layer. The laser sintering area of ​​the mold core forms a mold core with a dense structure. The laser sintering area of ​​the exhaust insert forms an exhaust insert with multiple gap hole structures. The exhaust insert and the mold core integrated structure. The invention also discloses the mold core of the exhaust insert.

Description

technical field [0001] The invention relates to the technical field of mold preparation, in particular to a method for 3D printing an integrated structure exhaust insert mold core, and the exhaust insert mold core for implementing the method. Background technique [0002] Because injection molds require an exhaust system, especially in deep bone areas. At present, many mold manufacturers use the form of inserts to solve the problem of trapped air in the place where the air is trapped. Since the insert and the mold core are two separate entities, there will be a gap when the mold is assembled, and the pressure is very high during injection molding. If it is too large, it will often produce a front in the gap between the insert and the mold core, which will affect the appearance of the injection molded product and fail to meet the customer's requirements. Contents of the invention [0003] This invention is aimed at the deficiencies of the current technology, and provides a...
