SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sand box for casting to solve the current fastener dismantlement that proposes among the above-mentioned background art and more be troublesome, the part is lost easily, and fixed back if the screw takes place not hard up when using, causes the dislocation of cope flask and drag flask easily, influences the problem of using.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a sand box for casting, includes cope flask, drag flask and the four groups lugs that set up in cope flask and drag flask both sides, the protruding piece of cope flask (1) both sides fixedly connected with, the inside recess that is equipped with of protruding piece, recess bottom one side is run through and is equipped with the through-hole, through-hole one side is equipped with the support, the inside screw that runs through of support, the drag flask both sides correspond with protruding piece and are equipped with the telescopic link, the outside spring that is equipped with that encircles of telescopic link, telescopic link top fixedly connected with ejector pad.

When the cope flask and the drag flask are combined, the telescopic rod is inserted into the groove of the protruding block, when the cope flask and the drag flask just contact with each other, the telescopic rod enters the through hole under the action of the spring to be fixed, the sand flask is effectively prevented from moving when in use, the use is influenced, and the use is more convenient.

Preferably, every group the lug center department all is equipped with the fixed block, the inside screw hole that is equipped with of fixed block is favorable to fixing cope flask and drag flask.

Preferably, one side of the top of the groove is provided with a certain angle.

Preferably, the bracket is fixedly connected with the protruding block.

Preferably, the telescopic rod is matched with the groove.

Preferably, one side of the push block is provided with a certain angle, and the inclination angle of the groove is matched with that of the push block.

The utility model has the advantages that:

through setting up telescopic link and recess, be favorable to when cope flask and drag flask mould assembling, the telescopic link inserts the recess of outstanding piece, and when cope flask and drag flask just contacted, the telescopic link supports the recess inner wall under the effect of spring and fixes, and the effectual sand box of avoiding takes place to remove when using, influences the use for use convenience more.
