Resin sand core 3D printing device facilitating batch production

Abstract

The invention provides a resin sand core 3D printing device facilitating batch production. The 3D printing device comprises a base. Guide rails are fixed to the two sides of the base correspondingly and are parallel. Guide wheels are arranged on the guide rails and move along the guide rails. The guide wheels are fixed below sliding block assemblies and controlled by the sliding block assemblies to rotate. Door frames are vertically fixed to the sliding block assemblies. The top ends of the two door frames are fixedly connected through a horizontal cross beam. Guide rods are arranged on the tops of the door frames and fixed below the cross beam. According to the 3D printing device, by means of the portal frame structure formed by the door frames and the cross beam, and related structure arrangement, it can be ensured that the position of the base is not blocked before operation is carried out and after operation is completed, due to the open type structure, smooth progressing of batchproduction is facilitated greatly, the related cost of transferring and carrying is omitted, and thus the overall cost is reduced substantially.

Description

technical field [0001] The invention relates to a resin sand sand core 3D printing device which is convenient for batch production. Background technique [0002] The traditional resin sand core production mainly relies on manual operation of the mold to ensure the structure and size of the sand core. There are many problems in mold design, long production cycle, high cost, etc., and the precision of the mold will decrease after long-term use, and human factors will affect the sand core. The performance index has a great influence, and the consistency of the sand core is poor, which affects the quality of the casting. [0003] Therefore, applying 3D printing technology to the production of resin sand cores can effectively ensure the consistency of sand cores and the quality of castings in theory, and the mold design is simpler, the production cycle is shorter, and the cost is lower. [0004] However, the current 3D printing technology basically uses two vertical and horizont...

Problems solved by technology

[0004] However, the current 3D printing technology basically uses two vertical and horizontal moving rods to move horizontally and vertically to drive the discharge nozzle to move horizontally, which means that the whole is often a frame structure, and batch production Larger handling equipment is often required during production. In this case, the overall frame structure is outdated, and an independent equipment is often required for transfer and handling, which is costly
