Laser 3D printing platform for sand mold making with heated sand box

Abstract

The invention belongs to the technical field of sand mold 3D printing equipment, and in particular relates to a laser 3D printing platform for sand mold making with a heating sand box, which is characterized in that it includes a base, a column arranged around the base, and a suspension frame arranged on the top of the column , a lifting system set on the base, a shifting system set above the lifting system, a sanding platform set on the shifting system, a heating sand box surrounding the sanding platform and located on the upper part of the printing area, setting The collecting box on the side plate of the heating flask, and the top of the heating flask is fixedly connected with the suspension frame by bolts. The invention brings quickness and convenience to the process inspection and process correction of the sand mold. It has a stable structure, high transmission efficiency, and the printing platform can move up and down. Ensure that the temperature of the sand material on the sand spreading platform is constant and the temperature loss is small, so as to improve the bonding quality and solidification rate of the sand material.

Description

technical field [0001] The invention belongs to the technical field of sand mold 3D printing equipment, and in particular relates to a laser 3D printing platform for sand mold making with a heated sand box. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. It is often used in mold manufacturing, Fields such as industrial design are used to make models. The current 3D printing technology is mostly used in the printing of plastic products and printing of specific metal materials, but it has just started in the production of casting sand molds. The traditional sand mold making is to make the wooden or metal mold of the parts first, and then make the sand mold based on the wooden or metal mold of the parts. In this way, in the early stage of production, if the process and shape need to ...

Problems solved by technology

The traditional sand mold making is to make the wooden or metal mold of the parts first, and then make the sand mold based on the wooden or metal mold of the parts. In this way, in the early stage of production, if the process and shape need to be changed during the sand mold inspection, it must be Modify or redo the wooden and metal molds of the parts, so that the sand molds can be mass-produced after repeated verifications. This process takes a long time, resulting in a prolongation of the production cycle of the parts, which often affects the progress of the entire equipment and increases the cost of the equipment. The 3D printer for casting sand molds The above-mentioned problems can be overcome, and the 3D printing platform of the casting sand mold, as its main structural component, is particularly important in the casting sand mold 3D printer.
