Casting sand box provided with positioning and locking mechanism and convenient to cool and separate

Abstract

The invention discloses a casting sand box provided with a positioning and locking mechanism and convenient to cool and separate. The casting sand box provided with the positioning and locking mechanism and convenient to cool and separate comprises a first sand box, a second sand box matched with the first sand box is arranged at the bottom of the first sand box, a first upper frame and a first lower frame are respectively arranged at the top and the bottom of the first sand box, a plurality of positioning holes are formed in the bottom of the first lower frame, heat dissipation components are arranged on the front face and the back face of the first sand box, and heat dissipation passages matched with the heat dissipation components are formed in the inner wall of the first sand box; and a second upper frame and a second lower frame are arranged at the top and the bottom of the second sand box respectively, a plurality of positioning and locking mechanisms matched with the positioning holes are uniformly arranged at the top of the second upper frame, a second heat dissipation cavity is formed in the inner wall of the second sand box, and a plurality of heat dissipation openings communicating with the second heat dissipation cavity are uniformly formed in the outer side of the bottom of the second sand box. The casting sand box provided with the positioning and locking mechanism and convenient to cool and separate has the beneficial effects that the first sand box and the second sand box can be quickly positioned and assembled, and the use efficiency of the sand box is improved.

Description

technical field [0001] The invention relates to the technical field of casting sand boxes, in particular to a casting sand box with a positioning and locking mechanism which is convenient for cooling and separation. Background technique [0002] Casting is a process in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after cooling, solidification, and cleaning treatment, a casting with predetermined shape, size and performance is obtained. Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of modern device manufacturing industry. [0003] In the casting process, sand boxes are often used as molds filled with molding sand. At present, in terms of shape, sand boxes can be divided into rectangular sand boxes, round sand boxes or sand boxes of other shapes. Patent No. CN20191119...

Problems solved by technology

Patent No. CN201911195718.X discloses a casting sand box locking and positioning device, which solves the problem of poor practicability of the sand box in the prior art due to poor adjustment ability and locking ability during use. However, The following problems exist in its use:

[0004] Since the first sand box and the second sand box are locked by several locking box components, when the sand box body needs to be assembled and disassembled, It is necessary for the staff to operate individual locking box components one by one. Only when all the locking box components are operated can the locking or separation between the first sand box and the second sand box be realized, which makes the operation process too cumbersome. The use effect is poor; in addition, when the sand box is cooled in the prior art, it is usually poured and shaped by natural cooling. Due to the cooling by natural cooling, the solidification time is longer, which seriously affects the molding time of the mould. , reduce production efficiency
