Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Please refer to Figures 1 - 4, the present utility model provides a dewaxing device for the production of stainless steel castings, including a base 1: a dewaxing furnace 2 is fixed at the top of the base 1; a placement plate 4 is slidably connected to the inner side of the dewaxing furnace 2; both sides of one end of the placement plate 4 are fixedly provided with fixing blocks 9; the fixing blocks 9 are slidably connected to the dewaxing furnace 2; both sides of the other end of the placement plate 4 are fixedly provided with sliding blocks 12; the sliding blocks 12 are slidably connected to the dewaxing furnace 2; both the upper and lower ends of the sliding blocks 12 are fixedly provided with limiting blocks 13; the limiting blocks 13 are slidably connected to the dewaxing furnace 2; a moving component is arranged at a position corresponding to the placement plate 4 inside the dewaxing furnace 2 for moving the placement plate 4; a steam spraying component is arranged at the inner top of the dewaxing furnace 2 for steam heating the mold. When working, first place the product to be dewaxed on the top of the placement plate 4, and then drive the fixing blocks 9 to move through the moving component, so as to drive the placement plate 4 to move simultaneously through the fixing blocks 9, and then drive the placement plate 4 to move inside the dewaxing furnace 2. Then, the workpiece can be heated and dewaxed through the steam spraying component. After dewaxing is completed, the placement plate 4 can be moved out of the dewaxing furnace 2 through the moving component. This step is designed with the cooperation structure of the moving component and the fixing blocks 9, so that when it is necessary to take out the workpiece from the inside of the dewaxing furnace 2, the fixing blocks 9 can be driven to move through the moving component, and then the placement plate 4 can be driven to move out of the dewaxing furnace 2 through the fixing blocks 9, effectively avoiding the situation where workers are scalded by manually taking out the workpiece, and improving the safety of the labor force;

[0026] Further, as Figure 2 and Figure 3 shown, the moving component includes two driving screws 10; the two driving screws 10 are respectively arranged at both sides of the placement plate 4; the driving screws 10 are rotatably connected to the dewaxing furnace 2; the driving screws 10 are rotatably connected to the sliding blocks 12; an internal threaded rod 11 is threadedly connected to the outer side of one end of the driving screw 10 close to the fixing block 9; the internal threaded rod 11 is fixedly connected to the fixing block 9; a driving component is arranged at a position corresponding to the driving screw 10 inside the dewaxing furnace 2. When working, when it is necessary to move the placement plate 4, first drive the driving screw 10 to rotate through the driving component. When the driving screw 10 rotates, it can drive the fixing block 9 to move through the internal threaded rod 11 threadedly connected thereto, and then drive the placement plate 4 to move simultaneously to move the workpiece located on the top of the placement plate 4 out of the dewaxing furnace 2. This step can drive the internal threaded rod 11 to move through the rotation of the driving screw 10, and then push the placement plate 4 through the movement of the internal threaded rod 11.

[0027] Further, as Figure 2 and Figure 3As shown in the figure, the driving component includes a transmission rod 14; the transmission rod 14 is arranged inside the dewaxing furnace 2 at a position corresponding to the placement plate 4; the transmission rod 14 is rotatably connected to the dewaxing furnace 2; a transmission worm gear 17 is fixed on the outer side of the middle of the transmission rod 14; a driving motor 19 is fixed inside the dewaxing furnace 2 at a position corresponding to the transmission worm gear 17; a transmission worm 18 is fixed at the output end of the driving motor 19; the transmission worm 18 is meshed with the transmission worm gear 17; the transmission rod 14 is connected to the driving screw 10 through a transmission component. When working, when it is necessary to drive the driving screw 10 to rotate, first start the driving motor 19, so that the driving motor 19 drives the transmission worm 18 to rotate. When the transmission worm 18 rotates, it drives the transmission rod 14 to rotate through the transmission worm gear 17 meshed with it. When the transmission rod 14 rotates, it drives the driving screw 10 to rotate through the transmission component. Through the matching structure design of the transmission worm 18 and the transmission worm gear 17 in this step, when the driving motor 19 is started, the transmission rod 14 can be driven to rotate, and thus when the transmission rod 14 rotates, it drives the driving screw 10 to rotate through the transmission component.

[0028] As Figure 2 and Figure 3 shown in the figure, the transmission component includes a driving bevel gear 15, and the driving bevel gear 15 is fixed at both ends of the transmission rod 14; a transmission bevel gear 16 is fixed at a position corresponding to the driving bevel gear 15 on the driving screw 10; the driving bevel gear 15 is meshed with the transmission bevel gear 16. When working, when the transmission rod 14 rotates, it drives the driving bevel gear 15 to rotate. When the driving bevel gear 15 rotates, it drives the driving screw 10 to rotate through the transmission bevel gear 16 meshed with it. This step facilitates the design of the matching structure of the driving bevel gear 15 and the transmission bevel gear 16, so that when the driving bevel gear 15 rotates, it can drive the driving screw 10 to rotate through the transmission bevel gear 16.

[0029] As Figure 2 shown in the figure, one end inside the base 1 and at a position corresponding to the fixed block 9 is rotatably connected with a telescopic support rod 20; the telescopic end of the telescopic support rod 20 is rotatably connected with the fixed block 9. When working, when one end of the placement plate 4 moves to the outside of the dewaxing furnace 2, it drives the telescopic support rod 20 to rotate around the end away from the placement plate 4. This step can, through the structural design of the telescopic support rod 20, play a role in supporting the placement plate 4, thereby preventing the placement plate 4 from tilting and improving the stability of the placement plate 4.

[0030] As Figure 2As shown, a flow guide plate 5 is fixed to the lower end of the placement plate 4; a wax storage tank 6 is provided at the lower end of the base 1; the top end of the wax storage tank 6 extends to the inner side of the base 1 and corresponds to the position of the flow guide plate 5. During operation, when the heated wax melts, it flows from the top end of the placement plate 4 through the flow guide plate 5 to the wax storage tank 6, thereby enabling the collection of the wax. This step facilitates the centralized collection of the used wax for subsequent recycling, effectively avoiding waste of resources.

[0031] As Figure 2 shown, the steam spraying assembly includes a high-pressure steam tank 3, and the high-pressure steam tank 3 is fixed at the top position of the dewaxing furnace 2; flow guide pipes 7 are fixed to both sides of the lower end of the high-pressure steam tank 3; one end of the flow guide pipe 7 away from the high-pressure steam tank 3 extends to the inner top end of the dewaxing furnace 2; a plurality of nozzles 8 are evenly fixed to the lower end of the flow guide pipe 7. During operation, when the mold needs to be dewaxed, the high-temperature steam inside the placement plate 4 is ejected outward through the flow guide pipes 7 and the nozzles 8 by the high-pressure steam tank 3. Furthermore, the workpiece located at the top end of the placement plate 4 can be evenly heated through the plurality of nozzles 8. Through the structural design of the plurality of nozzles 8 in this step, the workpiece can be evenly heated, thereby avoiding an overly long dewaxing processing time, effectively improving the dewaxing work efficiency, reducing waste of resources, and enhancing the practicality of the device.

[0032] Working principle: During operation, first place the product to be dewaxed on the top of the placement plate 4. Subsequently, drive the fixed block 9 to move through the moving component, thereby driving the placement plate 4 to move simultaneously through the fixed block 9, and then driving the placement plate 4 to move inside the dewaxing furnace 2. Then, the processed part can be heated and dewaxed through the steam spraying component. After dewaxing is completed, the placement plate 4 can be moved out of the dewaxing furnace 2 through the moving component; when the placement plate 4 needs to be moved, first drive the driving screw rod 10 to rotate through the driving component. When the driving screw rod 10 rotates, it can drive the fixed block 9 to move through the built-in threaded rod 11 threadedly connected thereto, and then can drive the placement plate 4 to move simultaneously to move the processed part located on the top of the placement plate 4 into the dewaxing furnace 2; when the driving screw rod 10 needs to be rotated, first start the driving motor 19, so that the driving motor 19 drives the driving worm 18 to rotate. When the driving worm 18 rotates, it drives the transmission rod 14 to rotate through the transmission worm wheel 17 meshed therewith. When the transmission rod 14 rotates, it drives the driving screw rod 10 to rotate through the transmission component; when the transmission rod 14 rotates, it drives the driving bevel gear 15 to rotate. When the driving bevel gear 15 rotates, it drives the driving screw rod 10 to rotate through the transmission bevel gear 16 meshed therewith; when one end of the placement plate 4 moves to the outside of the dewaxing furnace 2, it drives the telescopic support rod 20 to rotate around the end away from the placement plate 4; when the heated wax melts and flows from the top of the placement plate 4 to the wax storage tank 6 through the diversion plate 5, the wax can be collected; when the mold needs to be dewaxed, the high-temperature steam inside the placement plate 4 is sprayed outwards through the diversion pipe 7 and the nozzle 8 by the high-pressure steam box 3, and then the processed part located on the top of the placement plate 4 can be uniformly heated through a plurality of nozzles 8.

[0033] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
