Resin casting mould rapid manufacturing method

Abstract

The invention belongs to the technical field of material processing engineering, and in particular relates to a resin casting mould rapid manufacturing method. The resin casting mould rapid manufacturing method is characterized by comprising the following steps of: (1) drawing a three-dimensional CAD (Computer-Aided Design) model of a mould according to a casting process drawing of a casting, and preparing a resin prototype for manufacturing a resin casting mould by a rapid prototyping device; (2) rapidly obtaining a die cavity for manufacturing the resin casting mould through a rolling over of a room temperature vulcanized silicone rubber mould by utilizing the prepared resin prototype; (3) manufacturing the resin mould through a manual paste mode by utilizing the die cavity for manufacturing the resin casting mould; and (4) assembling the resin mould prepared by manual paste on a mouldboard to complete the manufacturing process of the mould. Compared with the prior art, the invention has the advantages of facilitating design and modification to the appearance of the casting, being capable of rapidly obtaining the die cavity for manufacturing the resin casting mould, manufacturing the mould with a few tenths of millimeter of dimensional accuracy and shortening the manufacturing cycle of the mould.

Description

technical field [0001] The invention belongs to the technical field of material processing engineering, and in particular relates to a rapid manufacturing method of a resin casting mold. Background technique [0002] At present, most of the casting molds used for modeling in the domestic casting production process are made of red pine wood and processed by hand. The quality of casting molds and the speed of design and manufacturing are the key technical equipment for enterprises to win severe market competition. In the past, the production process of casting molds generally used the product drawings provided by customers or the actual castings to design the mold structure, and then used manual lofting, mold making and assembly. For casting molds with complex shapes, the production cycle is long and difficult. , the shape dimension accuracy and surface finish of the model are relatively low.

Problems solved by technology

In the past, the production process of casting molds generally used the product drawings provided by customers or the actual castings to design the mold structure, and then used manual lofting, mold making and assembly. For casting molds with complex shapes, the production cycle is long and difficult. , the shape dimension accuracy and surface finish of the model are relatively low

In the mold making process, molds with complex curved surfaces need to be lofted multiple times, hand-carved or made with simple woodworking processing equipment, which prolongs the processing cycle of casting molds and high processing costs

The casting mold has a long processing cycle, which cannot well meet the requirements of the enterprise's product upgrading, which limits the development of the enterprise
