Sand mold manufacturing laser 3D printing platform with heating type sand boxes

Abstract

The invention belongs to the technical field of sand mold 3D printing equipment, and particularly relates to a sand mold manufacturing laser 3D printing platform with heating type sand boxes. The sand mold manufacturing laser 3D printing platform is characterized by comprising a base, stand columns arranged around the base, a suspension frame arranged on the tops of the stand columns, a lifting system arranged on the base, a displacement system arranged above the lifting system, a sand paving platform arranged on the displacement system, the heating type sand boxes surrounding the sand paving platform and located at the upper portion of a printing area, and collecting boxes arranged on side plates of the heating type sand boxes, and the tops of the heating type sand boxes are fixedly connected with the suspension frame through bolts. Rapidness and convenience are achieved through sand mold technology checking and technology correcting, and the sand mold manufacturing laser 3D printing platform is stable in structure and high in transmission efficiency. The printing platform can move up and down, each heating type sand box is formed by four heating plates in a defining manner, it is ensured that a sand mold printing layer is heated and solidified, accordingly, it is ensured that sand materials on the sand paving platform are constant in temperature, the temperature loss is low, and the sand material bonding quality and solidification rate are improved.

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.
