Laser 3D printing platform for sand mold making

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, 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, which is arranged on the The lifting system on the base, the shifting system arranged above the lifting system, the sand-laying platform arranged on the shifting system, the molding sand box surrounding the sand-laying platform, and the molding sand box set in the molding sand box The collecting box on the side plate and the top of the solidified sand box are fixedly connected with the suspension frame by bolts. The process inspection and process correction of the present invention are fast and convenient, with stable structure and high transmission efficiency. The printing platform can move up and down in the molding sand box 1 to ensure the layer-by-layer printing of sand molds. The molding sand box 1 is fixed by four-sided box boards with bolt assemblies It is formed to prevent the sand material from loose sand, improve the bonding quality of the sand material to ensure that the sand material in the area of ​​the sand mold workpiece is consolidated and shaped, and the sand material is conveniently transported.

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. 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 be changed during the s...

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 problems can be overcome. The laser 3D printing platform for sand mold making is the main structural component, and its role is particularly important in casting sand mold 3D printers.
