[0002] At present, in the process of investment casting, after dewaxing, the shell making process usually takes the shell out of the machine and then takes it to the baking place for baking. In this process, the operator needs to manually carry the shell, which increases the labor intensity, and the workbench cannot be automatically unloaded during transportation. In certain environments, such as in a small space, it is difficult for ordinary transportation equipment to move and fix.

[0003] In the prior art, there is a transfer device for the mold shell after dewaxing in investment casting, such as the Chinese patent number CN213678414U, which includes a storage rack, a transfer rack and a transport vehicle, the transport vehicle includes a bracket for carrying the dewaxing basket, the transfer rack includes a cylinder, a gantry and a controller, two cylinders are provided, the shells of the cylinders are respectively vertically arranged at the lower part of both sides of the gantry, the piston rod of the cylinder is connected to the lifting platform, the storage rack includes a bracket, the bracket is a hollow square frame structure, and a multi-layer loading platform is arranged in the cavity of the frame structure. The utility model uses the dewaxing basket as a turnover basket. After the mold shell is dewaxed, the dewaxing basket is transported and stored together with the mold shell, and multiple handling is not required, which reduces the labor intensity, prevents the mold shell from being damaged, and ensures smooth production.

[0004] However, in the prior art, in the investment dewaxing working environment, some workpiece transportation equipment is too large to adapt to the narrow environment and cannot be flexibly moved in the narrow environment. When the equipment needs to be fixed for a long time, it cannot have the function of both movable and fixed support. When transporting the workpiece after dewaxing, ordinary transportation equipment cannot unload the workpiece, and manual unloading of the workpiece is still required, which is time-consuming and labor-intensive.

The outer surface of the sliding table 18 is fixedly connected to a hinge 6, and the outer surface of the hinge 6 is fixedly connected to a workbench 4, and the lower surface of the workbench 4 contacts the upper surface of the sliding table 18. A toothed plate 19 is fixedly connected to the lower surface of the sliding table 18, and a gear 20 is meshed on the outside of the toothed plate 19. A lever 17 is fixedly connected to the inner surface of the gear 20, and the front end of the lever 17 is rotatably connected to the inner surface of the main shell 1, and the top end of the lever 17 contacts the lower surface of the workbench 4.

[0026] Working principle:

[0027] When in use, the guide rail 2 fixed on the upper surface of the main shell 1 drives the sliding table 18 to slide back and forth along the outer surface of the guide rail 2 under the rotation of the screw rod 9, and the hinge 6 is fixed on the outer surfaces of the sliding table 18 and the workbench 4, so that the sliding table 18 and the workbench 4 can be opened along the hinge 6, and then the toothed plate 19 fixed on the outer surface of the sliding table 18 drives the sliding table 18 to move under the rotation of the screw rod 9, thereby forcing the toothed plate 19 to move, and then the gear 20 fixed on the outer surface of the lever 17, due to the meshing action of the gear 20 and the toothed plate 19, causes the lever 17 to rotate, and the workbench 4 is lifted up under the rotation of the lever 17, so that the workbench 4 is at a downward angle, and the workpiece is automatically unloaded.

[0028] Under the reciprocating rotation of the motor 16, the belt 7 and the conveyor belt 28 drive the roller 8 and the screw 27 to rotate, thereby controlling the screw 9 fixed on the roller 8 to rotate, and the fixed plate 12 fixed on the screw 27 drives the fixed plate 12 to move and slide along the slide rail 11 under the rotation of the screw 27. The support rod 14 fixed on the inner surface of the fixed plate 12 has a sliding plate 15 fixed below. When the cylinders fixed on both sides of the sliding plate 15 move along the grooves in the guide plate 13, the support rod 14 is driven to move up and down, thereby driving the working plate 10 fixed on the top of the support rod 14 to move up and down, and because of the guide plate 13, the cylinders fixed on both sides of the sliding plate 15 move along the grooves of the guide plate 13, so that the sliding plate 15 can not only move up and down but also move horizontally, thereby controlling the working plate 10 to move up and down at both ends in the main shell 1 and horizontally in the middle, and cooperating with the workbench 4 to achieve alternating operation.

[0029] The roller 5 is fixed on the lower surface of the main shell 1 and can be used to move the equipment. The sleeve 22 fixed on the lower surface of the main shell 1 forces the support foot 24 fixed on the lower surface of the spring 23 to pull up the support foot 24 due to the contraction of the spring 23 when the pedal 26 is retracted.

[0030] A connecting block 25 is fixed on the outer surface of the sleeve 22, and a fixing column 21 is fixed on the outer surface of the support leg 24, and a pedal 26 is fixed on the outer surface of the fixing column 21.
