Further, when the first hydraulic cylinder is pushed out, the cover plate and the top cover of the sand box form a closed chamber.

Furthermore, a sand storage box is arranged above the cross beam, two sand discharge pipes are arranged at the lower end of the sand storage box, the sand discharge pipes are soft pipelines, two sand discharge openings are formed in the cover plate, and the sand discharge pipes are connected with the sand discharge openings.

Furthermore, the push-out plate and the cover plate are both provided with clamping grooves used for clamping the mold cores.

Furthermore, the first hydraulic cylinder and the second hydraulic cylinder are long-stroke hydraulic cylinders, and the third hydraulic cylinder is a short-stroke cylinder.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, high durability and convenient use starts first pneumatic cylinder in the use and makes the sand box be encapsulated situation to pack through storing up the sand box, the sand discharge pipe, pack and compress tightly the sand material through the pressure strip of both sides after accomplishing, release through the sand material after the second pneumatic cylinder will compress tightly after accomplishing, thereby accomplished pack, press the material and get the three process of material, effectively improved the preparation efficiency of casting sand mould, and all be provided with the draw-in groove on pushing out board and apron, in order to do benefit to fixed mold core.
