Abstract
The utility model discloses a foundry sand case, including upset frame, die block and hydraulic pressure post, still include and arrange the roof between upset frame and the die block in, the roof hollows out corresponding to the jut of die block, makes the roof overlap in the bottom of the jut of die block, the hinge joint of this roof four corners and hydraulic pressure post. The utility model discloses simple structure, convenient to use, demoulding effect is good, has practiced thrift manufacturing cost, has improved production efficiency, low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of foundry sand die device, particularly relates to a kind of sand box used for casting.
Background technology
Current sand box used for casting, when the demoulding, due to the corner discontinuity of box-frame, cause sand mo(u)ld to fall limit arrisdefect, sand mo(u)ld is of poor quality, and qualification rate is low, uses inconvenience, and production cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sand box used for casting that can make the uniform stressed demoulding of box-frame corner.
In order to solve the problems of the technologies described above, sand box used for casting of the present utility model, comprise box-frame, bed die and hydraulic column, also comprise the top board be placed between box-frame and bed die, the jut that described top corresponds to bed die hollows out, make top board be placed on the bottom of the jut of bed die, this top board corner is connected with the piston of hydraulic column.
Adopt structure of the present utility model, owing to being provided with top board, in use, the hydraulic column of top board corner is simultaneously by top board slowly jack-up, and namely monoblock top board is by box-frame slowly jack-up, uniform force, and sand mo(u)ld quality is good, and qualification rate is high.The utility model structure is simple, and easy to use, stripping result is good, has saved production cost, has improve production efficiency, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, sand box used for casting of the present utility model, comprises box-frame 2, bed die 1 and hydraulic column 4, also comprises the top board 3 be placed between box-frame 2 and bed die 1.The jut that top board 3 corresponds to bed die 1 hollows out, and make top board 3 be placed on the bottom of the jut of bed die 1,3 four jiaos, this top board is connected with the piston of hydraulic column.
