Problems solved by technology

[0003] The joints of the existing sandboxes used for metal casting are not strong enough, and the phenomenon of lifting the box is easy to occur during pouring, resulting in scrapped castings. Some sandboxes are connected by bolts at the joints. Although the connection is reliable, molten iron is easy to splash onto the On the thread of the bolt, the bolt is damaged and cannot be disassembled

Abstract

The invention discloses a sand box for metal casting, relates to the technical field of metal casting, and mainly solves the problem of weak connecting places in a traditional sand box. The sand box comprises a base; a support plate is arranged on the base; the support plate is designed as a rectangle; hydraulic columns are uniformly arranged in the support plate; the hydraulic columns are fixedly connected with a lower shell; the lower shell is connected with an upper shell; a fixed flange is arranged in the connected place of the lower shell and the upper shell; a fixed hole is formed in the fixed flange; an U type clamping ring is inserted in the fixed hole; ventilation plates are mounted on the front side and the back side of the lower shell; ventilation holes are uniformly arranged on the front and back sides of the upper shell and the lower shell; fine rods are uniformly distributed on the ventilation plates; and the ventilation plates are connected with the upper shell and thelower shell through the ventilation holes and the fine rods. Through the structure, the connecting reliability of the sand box is effectively improved, and the box hoisting and connected place waste phenomenon is prevented.

Description

technical field [0001] The invention relates to the technical field of metal casting equipment, in particular to a sandbox for metal casting. Background technique [0002] Sandboxes are often used in foundry companies to produce accessories. Traditional sandboxes require manual molding by master workers. The molding process is all done by hand or hand tools. Manual molding is flexible in operation, wide in adaptability, simple in process equipment, and low in cost. [0003] The joints of the existing sandboxes used for metal casting are not strong enough, and the phenomenon of lifting the box is easy to occur during pouring, resulting in scrapped castings. Some sandboxes are connected by bolts at the joints. Although the connection is reliable, molten iron is easy to splash onto the On the thread of the bolt, the bolt is damaged and cannot be disassembled. Contents of the invention [0004] The purpose of the embodiment of the present invention is to provide a sandbox for...
