Embodiment
Particular content of the present utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, lost foam casting sandbox structure, including：Lost foam casting sandbox structure, bag
Include：Sandbox body 1 and the case lid 2 for being arranged on the upper end of sandbox body 1, screen pack 3 is fixedly installed in the sandbox body 1,
Slided in the sandbox body 1 of the upper end of screen pack 3 and be provided with sand container orifice plate 4, the top of the sand container orifice plate 4 is founder
Make chamber 5, the lower section of the sand container orifice plate 4 is negative pressure cavity 6, and half is provided with the sandbox body 1 of the upper end both sides of screen pack 3
Circular guide rod 7, the semicircle to be cooperated with semicircle guide rod 7 is respectively arranged with the both sides of the sand container orifice plate 4 and is led
To hole 8, the upper end of the sand container orifice plate 4 is provided with filter cloth 9, jacking is symmetrically arranged with the two bottom sides of the negative pressure cavity 6
Cylinder 10, the piston rod 11 of the jacking cylinder 10 are connected with fixed block 12 through screen pack 3, set in the fixed block 12
Rotating shaft 13 is equipped with, the lower end of sand container orifice plate 4 is rotatably arranged in rotating shaft 13 by moving block 14 respectively, in the sandbox body 1
Side lower end be provided with negative pressure cavity 6 be interconnected exhaust tube 15, be provided with the opposite side upper end of the sandbox body 1
Discharging swash plate 16.
In use, starting jacking cylinder 10, the piston rod 11 of jacking cylinder 10 drives above-mentioned lost foam casting sandbox structure
