The driven rod 23 drives the rotating gear 29 to rotate, the rotating gear 29 drives the two racks 28 to move reversely, so that the two piston rods 27 move reversely, two sealed cavities formed by the two sleeves 26 and the two piston rods 27, the two piston rods 27 move reversely, so that the space of one sealed cavity is increased, the space of the other sealed cavity is decreased, when the space of the sealed cavity is increased, slurry in the box body 24 flows into the sleeve 26 from the pumping pipe 38, when the space of the sealed cavity is decreased, the slurry in the sleeve 26 is sprayed out from the discharging pipe 25 to the joint of the upper die 5 and the lower die 6, as the motor 13 drives the sealing mechanism to move, the sleeve 26 rotates, so that the joint of the upper die 5 and the lower die 6 is sprayed circularly, meanwhile, the sleeve 26 moves to drive the fixed pipe 31 to move, the fixed pipe 31 drives the sliding rod 32 to move, the sliding rod 32 drives the hairbrush 34 to move, the brush 34 brushes the slurry sprayed at the joint, so that the slurry can better seal the joint, the spring 33 is in a compressed state, the restoring force of the spring 33 generates outward thrust on the sliding rod 32, the sliding rod 32 generates outward thrust on the brush 34, the brush 34 is tightly attached to the mold, and a better brushing effect is realized.

The one-way valve on the pumping pipe 38 can only feed and can not discharge, and the one-way valve on the discharge pipe 25 can only discharge and can not feed, so that slurry can only enter the sealed cavity through the pumping pipe 38 and then is sprayed out of the discharge pipe 25.

Here, when the sealing mechanism circles around the mold for one circle, the rotary gear 29 drives the two piston rods 27 to respectively move to the extreme positions, at this time, one of the piston rods 27 abuts against the top of the sleeve 26, namely, the slurry in the sleeve 26 is just sprayed out, the other piston rod 27 moves to the tail of the sleeve 26, namely, the sealing cavity in the sleeve 26 is filled with the slurry, so that when the sealing mechanism seals the mold for one circle, the slurry in one of the sleeves 26 is just sprayed out, the slurry in the other sleeve 26 is just replenished, then the motor 13 is operated in the reverse direction, so that the sleeve 26 filled with the slurry sprays out, the other sleeve 26 is replenished, and therefore, the slurry is brushed on the joint for multiple times, and a better sealing effect is achieved.

In order to provide a non-return valve at the connection of the tapping pipe 38 and the sleeve 26, a non-return valve is provided at the connection of the tapping pipe 25 and the sleeve 26.

In order to seal the junction between the upper and lower dies 5, 6, slurry is provided in the tank 24.

The device passes through the shaping of forming mechanism realization melt, carry out the centre gripping to last mould 5 and lower mould 6 through two clamping unit, realize better closed effect, it is rotatory round the mould through drive assembly drive sealing mechanism, simultaneously, through the operation of drive assembly drive driven subassembly, make driven subassembly drive mobile unit reverse movement, thereby make two spout the material unit and spout material and feed supplement respectively, slow down through the rotational speed of speed reduction subassembly to motor 13, make during the rotatory round of sealing mechanism, two sleeves 26 just accomplish and spout material and feed supplement, brush spun mud through applying paint the unit with a brush, make mud better seal last mould 5 and lower mould 6 junction, realize better shaping effect, and use mud to seal, the cost is lower.

Compared with the prior art, this metal casting device with grinding apparatus sealing function, realize the shaping through forming mechanism, realize the sealing of mould 5 and lower mould 6 junction through sealing mechanism, realize better shaping effect, compare with current metal casting device, the device carries out the centre gripping to last mould 5 and lower mould 6 through spacing subassembly, realize better closed effect, and through the spary mud, realize better sealed effect, compare with current sealing mechanism, this mechanism passes through drive assembly and sealing component's linkage, online spary has been realized, the circulation operation of material spraying and feed supplement is realized through the cooperation of two sleeves 26 simultaneously, make the device can be quick spray the junction repeatedly, the efficiency is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
