Description

Technical Field

[0001] This utility model relates to the field of dewaxing machine technology, specifically a dewaxing machine for metal casting. Background Technology

[0002] Currently, in the machinery industry, high-precision parts are usually cast using investment casting. The investment casting process includes pressing wax patterns, assembling trees, making shells, dewaxing, baking, and casting into castings. During dewaxing, the workpiece needs to be placed in a dewaxing machine for processing. Dewaxing is usually done using hot water dewaxing, where the workpiece is immersed in a solvent and the solvent is heated to remove the wax film adhering to the surface of the workpiece.

[0003] A search revealed a utility model patent in China with patent publication number CN217142227U, which discloses a dewaxing machine for metal casting. The general description includes a housing with heating tubes evenly spaced at the bottom. Both ends of the heating tubes are fixed to the side walls of the housing. During use, the heating tubes and heating box fully heat the liquid inside the housing, and the stirring blades agitate the liquid, causing it to wash the surface of the workpiece, accelerating the dewaxing speed and improving the effect. However, the above device still has certain shortcomings, such as low working efficiency, limited workpiece capacity, and the need to remove dewaxed workpieces from the U-shaped bracket before placing new ones, which is cumbersome and time-consuming. It is also inconvenient to pre-place workpieces, and each U-shaped bracket can only hold a limited number of workpieces per dewaxing cycle. Therefore, we propose a dewaxing machine for metal casting.

[0026] Example

[0027] Please see Figures 1-4 A dewaxing machine for metal casting, comprising:

[0028] Base 1;

[0029] The dewaxing mechanism is mounted on the base 1 and includes a dewaxing box 2 and a support column 3. Both the dewaxing box 2 and the support column 3 are fixedly connected to the base 1. The support column 3 has an installation groove, in which a motor 4 is installed. The output end of the motor 4 extends through the installation groove and is fixedly connected to a support plate 5. Two electric cylinders are mounted through the support plate 5, and the output ends of the electric cylinders are fixedly connected to a cover plate 6. A support frame 7 is fixedly connected to the cover plate 6. Three mesh placement slots 8 are slidably connected to the support frame 7. Each mesh placement slot 8 has a movable groove, in which a fixed shaft 9 is fixedly connected. Two movable blocks 10 are slidably connected to the fixed shaft 9. A spring is fitted onto the fixed shaft 9, located between the two movable blocks 10. A locking block 11 is fixedly connected to each movable block 10. The frame 7 has multiple slots, and one end of the locking block 11 is located in the slot. The dewaxing box 2 is equipped with a second motor 12, two heating plates 13 and two heating tubes 14. A protective cover 15 is fixedly connected inside the dewaxing box 2. Two stirring racks 16 are rotatably connected inside the dewaxing box 2. The stirring racks 16 pass through the protective cover 15. The output end of the second motor 12 passes through the dewaxing box 2 and is fixedly connected to one of the stirring racks 16. The two stirring racks 16 are connected by a transmission mechanism. The placement mesh trough 8 is used to place the workpiece. The support frame 7 is used to support the placement mesh trough 8. The spring is used to provide elasticity. The locking block 11 is used to lock in the slot, making it easy for people to remove the placement mesh trough 8. The first motor 4 is used to rotate the support plate 5, the support frame 7, etc. The electric cylinder is used to cover the cover plate 6 on the dewaxing box 2 or the cleaning box 17.

[0030] The cleaning mechanism is mounted on the base 1 and includes a cleaning tank 17 and a water pump 18. Both the cleaning tank 17 and the water pump 18 are fixedly connected to the base 1. Two spray plates 19 are fixedly connected inside the cleaning tank 17. Water supply pipes are connected to the spray plates 19 and extend out of the cleaning tank 17. Water supply pipes 20 are connected to the two water supply pipes and are connected to the outlet of the water pump 18. The water pump 18 is used to supply water, and the spray plates 19 are used to spray water over a wide area to rinse multiple workpieces.

[0031] The support frame 7 has six sliding grooves, and sliders 21 are slidably connected in the sliding grooves. The six sliders 21 are in pairs. The mesh placement groove 8 is fixedly connected between two sliders 21 to support the mesh placement groove 8 and facilitate the sliding placement of the mesh placement groove 8.

[0032] The transmission mechanism includes two transmission wheels, which are fixedly mounted on two mixing frames 16 respectively. The two transmission wheels are connected by a transmission belt 22 to synchronously drive the two mixing frames 16 to rotate.

[0033] A baffle 23 is provided in the mounting slot to provide a shielding effect and improve the aesthetics.

[0034] Two telescopic rods 24 are fixedly connected through the support plate 5. The two telescopic rods 24 are fixedly connected to the two cover plates 6 respectively to improve the stability of the cover plates 6.

[0035] It should be further explained that the heating tube 14, heating plate 13, motor 4, motor 12, and electric cylinder in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The heating tube 14, heating plate 13, motor 4, motor 12, and electric cylinder are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0036] In summary, the working principle and process of this dewaxing machine for metal casting are as follows: First, place the machine at the desired location. Then, place the mesh tray 8 inside the support frame 7, allowing the slider 21 to slide into the groove. Next, move the two moving blocks 10, which compress the springs. This causes the locking block 11 to move. Once the locking block 11 aligns with the groove, release the moving blocks 10, the springs return, and the locking block 11 enters the groove, thus limiting the mesh tray 8. Disassembly follows the same principle. Then, start the electric cylinder, lowering it to cover the dewaxing chamber 2 with the cover plate 6. Start the second motor 12, heating tube 14, and heating plate 13. The heating tube 14 and heating plate 13 heat the solution previously placed in the dewaxing chamber 2. The second motor 12 drives one of the stirring frames 16 to rotate. Due to the transmission wheel and belt 22, the other stirring frame 16 also rotates. The stirring rack 16 agitates the solution in the dewaxing tank 2, causing the solution to rinse and dewax the workpiece. Simultaneously, the workpiece placement mesh trough 8 can be installed in another support frame 7. After dewaxing, the support frame 7 is raised, and the motor 4 is started. The motor 4 drives the support plate 5 and electric cylinder to rotate, positioning the undewaxed workpiece above the dewaxing tank 2 and the dewaxed workpiece above the cleaning tank 17. Then, the two electric cylinders drive the two cover plates 6 and the support frame 7 to descend. The water pump 18 is started, and because it has an external water supply pipe, it delivers water to the spray plate 19 through the water supply pipe 20 and the water delivery pipe. The spray plate 19 sprays water to rinse the workpiece. After rinsing, because the rinsing is fast, dewaxing is not yet complete. This time can be used to quickly replace the rinsed workpiece with the undewaxed one. This device is simple and quick to operate, improving practicality and work efficiency.

[0037] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
