Description

Technical Field

[0001] This utility model relates to the field of investment casting technology, specifically to a mold cleaning device for investment casting. Background Technology

[0002] Investment casting, also known as lost-wax casting, includes processes such as wax pressing, wax trimming, tree assembly, slurry application, wax melting, pouring molten metal, and post-processing. Lost-wax casting involves creating a wax model of the part to be cast, then coating the wax model with clay slurry to form a clay model. After the clay model dries, it is placed in hot water to melt the inner wax model. The melted clay model is then removed and fired to form a ceramic mold. A pouring gate is typically left during the clay model making process, through which molten metal is poured. After cooling, the desired part is formed.

[0003] A search revealed a Chinese patent (CN220658446U) disclosing a mold cleaning device for investment casting. The key technical features include: a support frame and an investment mold mounted on the support frame; support plates 1 fixed to both side walls of the support frame; a sliding plate between the two support plates 1; an electric telescopic rod 1 mounted on one support plate 1; a connecting plate hinged to the piston rod of the electric telescopic rod 1; a support plate 2 hinged to the end of the connecting plate away from the electric telescopic rod 1; a drive motor 1 fixed to the top of the support plate 2; the output shaft of the drive motor 1 passing through the support plate 2 and having a cleaning rod fixed thereon; a groove on the sliding plate that mates with the inner cavity of the investment mold; the cleaning rod passing through the groove; and a recycling component on the support frame for absorbing the cleaned residue. This device solves the problem of cumbersome and inconvenient manual cleaning operations in existing mold cleaning methods.

[0004] However, the existing cleaning rod has limited movement direction, which makes it inconvenient to clean the corners inside the mold groove, making it easy to miss some parts during cleaning and thus affecting the cleaning effect. In order to solve the problem of poor cleaning effect in the existing technology, this application moves the cleaning device in multiple directions by moving components such as vertical plates and crossbeams, thereby achieving the effect of cleaning any position inside the mold groove. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0014] 1. This utility model, by setting up components such as vertical plates and horizontal beams, and through the cooperation between the vertical plates and horizontal beams, enables the vertical plates and horizontal beams to move forward, backward, left, right, and up and down by driving the support components and cleaning components. This achieves the effect of adjusting the position of the cleaning components by setting up vertical plates and horizontal beams, thus solving the shortcomings of current technical solutions that are prone to omissions and have poor cleaning effects.

[0027] Please see Figure 1 , 23, 4, 5, 6, 7, 8. This utility model discloses a mold cleaning device for investment casting, comprising a base plate 1, a vertical plate 2 slidably connected to the upper surface of the base plate 1, a first driving block 3 slidably connected to the lower surface of the base plate 1, a first driving rod 4 internally threadedly connected to the first driving block 3, a second driving block 5 slidably connected to the outer surface of the vertical plate 2, a second driving rod 6 internally threadedly connected to the second driving block 5, a crossbeam 7 slidably connected to the outer surface of the vertical plate 2, a third driving block 8 slidably connected to the inner surface of the crossbeam 7, a third driving rod 9 internally threadedly connected to the third driving block 8, and a support member 10 slidably connected to the outer surface of the crossbeam 7.

The output end of the motor is fixedly connected to one end of the second drive rod 6, and the other end of the second drive rod 6 is rotatably connected to the vertical plate 2. A motor is fixedly installed on the outer surface of the crossbeam 7, and the output end of the motor is fixedly connected to one end of the third drive rod 9. The other end of the third drive rod 9 is rotatably connected to the crossbeam 7. The support member 10 is fixedly connected to the third drive block 8. A cleaning assembly consisting of a motor and a cleaning brush is installed inside the support member 10. A nozzle is installed on the outer surface of the support member 10. A water tank is fixedly installed on the upper surface of the base plate 1. The water tank contains washing liquid and a water pump is installed inside the water tank. The water tank and the nozzle are connected by a hose. The first drive rod 4 drives the vertical plate 2 and other components to move left and right through the first drive block 3. The second drive rod 6 drives the crossbeam 7 and other components to move up and down through the second drive block 5. The third drive rod 9 drives the support member 10 to move back and forth through the third drive block 8, thereby achieving the effect of driving the cleaning assembly to clean any position inside the mold groove.

[0028] A first outer shell 11 is fixedly connected to the upper surface of the base plate 1, and a second outer shell 12 is provided above the base plate 1. The first outer shell 11 and the second outer shell 12 are hinged together. Locks are provided on the front of the first outer shell 11 and the second outer shell 12. The second outer shell 12 and the first outer shell 11 seal the top of the base plate 1, thereby preventing the waste liquid generated during cleaning from splashing and polluting the environment.

[0029] A positioning plate 13 is fixedly connected to the inner wall of the second outer shell 12. A mold body 14 is provided on the outer surface of the positioning plate 13. The positioning plate 13 is used to position the mold body 14. When the second outer shell 12 is closed, the mold groove of the mold body 14 corresponds to the cleaning component inside the support member 10.

[0030] Two clamping blocks 15 are slidably connected to the outer surface of the positioning plate 13, and two first racks 16 are slidably connected to the inside of the positioning plate 13. Each clamping block 15 is fixedly connected to a first rack 16. The first rack 16 clamps and fixes the two sides of the mold body 14 by driving the clamping blocks 15 to slide.

[0031] The positioning plate 13 is rotatably connected to a first gear 17 and a second gear 18. The first gear 17 and the second gear 18 are fixedly connected, and the first gear 17 meshes with two first racks 16.

[0032] A pressure plate 19 is slidably connected to the outer surface of the positioning plate 13, and a support plate 20 is fixedly connected to the lower surface of the positioning plate 13. The pressure plate 19 is located above the mold body 14, and the support plate 20 is located below the mold body 14. The pressure plate 19 and the support plate 20 are used to clamp and fix the top and bottom of the mold body 14.

[0033] The positioning plate 13 has a fourth drive block 21 slidably connected inside, and a fourth drive rod 22 threadedly connected inside the fourth drive block 21. The positioning plate 13 also has a second rack 23 slidably connected inside. The fourth drive block 21 is fixedly connected to the pressure plate 19, and the fourth drive block 21 is fixedly connected to the second rack 23. The second rack 23 meshes with the second gear 18. A motor is fixedly installed inside the positioning plate 13. The output end of the motor is fixedly connected to one end of the fourth drive rod 22, and the other end of the fourth drive rod 22 is rotatably connected to the inside of the positioning plate 13.

[0034] The implementation principle is as follows: Opening the second outer shell 12 causes the positioning plate 13 and other components to rotate, placing the mold body 14 on the upper surface of the support plate 20. A motor drives the fourth drive rod 22 to rotate, which in turn causes the fourth drive block 21 to slide. The fourth drive block 21 then causes the pressure plate 19 and the second rack 23 to slide. The pressure plate 19 is in close contact with the top of the mold body 14. The second rack 23 drives the second gear 18 to rotate, which in turn drives the first gear 17 to rotate. The first gear 17 then causes the two first racks 16 to slide, which in turn causes the clamping block 15 to slide, thereby clamping the two sides of the mold body 14. The cleaning component is clamped from the side, and the second outer shell 12 is closed. The motor drives the first drive rod 4 to rotate, which in turn drives the first drive block 3 to slide. The first drive block 3 then drives the vertical plate 2 and other components to slide, thereby adjusting the distance between the cleaning component and the mold body 14. The motor drives the second drive rod 6 to rotate, which in turn drives the crossbeam 7 and other components to slide up and down via the second drive block 5, thereby adjusting the height of the cleaning component. The motor drives the third drive rod 9 to rotate, which in turn drives the support 10 to slide via the third drive block 8, thereby moving the cleaning component back and forth, thus cleaning the mold groove of the mold body 14.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
