Abstract

The invention relates to a method for rapidly manufacturing a mold through 3D printing materials. The method includes the following steps that (1) a mold model is designed through CAD; (2) the CAD mold model is designed into a thin shell model; (3) a fixing part is arranged on the thin shell model of the mold, and then a mold cavity is printed through a 3D printing device; (4) an upper mold core is machined through a CNC; (5) the mold cavity and the upper mold core are fixed to a standard mold frame; (6) the back face of the mold cavity is filled with sand for solidification; (7) a cover plate is installed on the back face of the mold cavity and fixed to the standard mold frame through a first connecting piece; and (8) mold manufacturing is completed. According to the method, the mold can be rapidly manufactured, the production time is saved, the efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention is a method for quickly making molds by using 3D printing materials, which belongs to the innovative technology of the method for quickly making molds by using 3D printing materials. Background technique [0002] The current molds are all digital models cut into physical models by CNC. Metal molds are then produced by casting. Due to the principle of mechanical processing, there will be processing dead angles, and the processing time of fine patterns is long. Coupled with the long casting process and shrinkage deformation, the quality and efficiency cannot be improved. Contents of the invention [0003] The object of the present invention is to provide a method for rapidly manufacturing molds using 3D printing materials in consideration of the above problems. The 3D printing mold cavity technology adopted in the present invention can save processes such as physical model processing and casting, and can also make the mold cavity produ...
