Abstract

The invention discloses a combined sand mold structure, which comprises a bearing base plate and a plurality of sand mold side bodies, at least one of the sand mold side bodies is an installation sand mold side body, and the installation sand mold side body is arranged on the bearing base plate through a connecting structure. The sand mold side body and the bearing bottom plate are printed and formed separately before assembly, therefore, an assembly auxiliary structure is provided on the sand mold side body and / or bottom plate to assist the positioning of the laser level or vernier caliper during the assembly process, so as to facilitate checking Install the alignment accuracy between the side body of the sand mold and the bearing base plate and assist in adjusting the position of the side body of the sand mold, so that the alignment of the side body of the sand mold and the bearing base plate is accurate.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a combined sand mold structure. Background technique [0002] Automobile companies continue to shorten the product development cycle, and the core castings such as engine cylinder block adopt mold opening and trial production in 60-90 days, which is difficult to meet the needs of verification samples in the product development process. Using 3D printing manufacturing technology to directly print sand cores and then group casting for moldless rapid manufacturing of cylinder castings can greatly shorten the trial production cycle of castings. Rapid prototyping requires sand molds to have a high pass rate of one-time casting, and requires high precision for sand molds to be artificially assembled. Contents of the invention [0003] The main purpose of the present invention is to propose a combined sand mold structure, aiming at improving the accuracy of sand mold artificial assem...
