Description

Technical Field

[0001] This utility model relates to the field of metal molded ball technology, and in particular to a metal molded ball closing device. Background Technology

[0002] Metal casting, commonly known as hard mold casting, is a process that uses metal materials to manufacture castings by pouring molten metal into a mold under gravity. Because a single metal mold can be used for hundreds to tens of thousands of castings, metal mold casting is also called permanent mold casting.

[0003] Currently, some existing metal casting ball molds require bolts to fix the two sets of molds after mold closing, in order to prevent molten metal from flowing out between the two sets of molds during casting. However, fixing the molds with bolts requires screwing several sets of bolts into the two sets of molds, which results in relatively low installation and fixing efficiency and relatively inconvenience. Therefore, we propose a metal casting ball mold closing device to solve or improve the above problems. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a metal casting ball clamping device, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a metal casting ball clamping device, including a first mold, a second mold disposed on one side of the first mold, a fixing frame fixed to the surface of the second mold, a second limiting rod inserted inside the fixing frame, a mounting block fixed to the top of the second limiting rod, a limiting claw rotatably mounted on the surface of the mounting block via a rotating shaft, a first spring sleeved on the surface of the second limiting rod, a first gear rotatably mounted on the bottom of the fixing frame via a support frame and a rotating shaft, a second gear fixed to one end of the rotating shaft of the first gear, a fixing plate fixed to the surface of the first mold, a first rack fixed to the surface of the fixing plate, and a second rack fixed to the bottom of the mounting block.

[0007] Furthermore, mounting plates are fixed to the surface of the first mold, and several sets of mounting plates are fixed in pairs around the circumference of the surface of the first mold.

[0008] Furthermore, a first limiting plate is placed on top of the mounting plate, and the first limiting plate is located between the two sets of mounting plates.

[0009] Furthermore, a first limiting rod is inserted inside the first limiting plate, and several sets of the first limiting rods are symmetrically inserted inside a set of first limiting plates. A second limiting plate is fixed to the surface of the first limiting rod.

[0010] Furthermore, the slider is fixed to the bottom end of the first limiting rod, the slider is located inside the first limiting plate and is slidably connected to the first limiting plate, and a second spring is sleeved on the surface of the first limiting rod.

[0011] Furthermore, the surface of the first mold is provided with a pouring gate, and the internal space of the pouring gate is connected to the internal space of the first mold.

[0012] This utility model has the following beneficial effects:

[0013] This invention, by setting a fixing plate, a first rack, and a second gear, allows the fixing plate to be inserted into the interior of the second mold when the first mold moves to one side of the second mold. This causes the fixing plate to move the first rack, which in turn drives the second gear to rotate via the first gear. The second gear then drives the second rack to move, which in turn moves the mounting block. This movement causes the mounting block to move the limiting pawl, and one end of the limiting pawl moves to one side of the first mold. Once the surfaces of the first and second molds are in contact and the molds are closed, the first rack disengages from the second gear. At this point, a first spring pulls the mounting block, which in turn pulls the limiting pawl, causing one end of the limiting pawl to hook onto the surface of the first mold. This pulls the first mold so that it is tightly attached to the surface of the second mold, thus fixing the first mold relatively to one side of the second mold. This method offers relatively high mold installation and fixing efficiency and is relatively convenient to use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5As shown, this utility model is a metal casting ball clamping device, including a first mold 1, a pouring gate on the surface of the first mold 1, the internal space of the pouring gate being connected to the internal space of the first mold 1, a second mold 2 disposed on one side of the first mold 1, mounting plates 4 fixed on the surface of the first mold 1, several sets of mounting plates 4 arranged in pairs around the surface of the first mold 1, limit holes being formed on the surface of the mounting plates 4, a first limiting plate 5 placed on the top of the mounting plates 4, the first limiting plate 5 being located between two sets of mounting plates 4, and a first limiting rod 15 inserted inside the first limiting plate 5. The top end of the first limiting rod 15 is inserted into a limiting hole on the surface of the mounting plate 4. The first limiting rod 15 and the limiting hole can restrict the position of the first limiting plate 5, preventing the first limiting plate 5 from detaching from the two sets of mounting plates 4. Several sets of first limiting rods 15 are symmetrically inserted inside one set of first limiting plates 5. A second limiting plate 17 is fixed to the surface of the first limiting rod 15. When the first limiting rod 15 moves, it will drive the fixed second limiting plate 17 to move. The slider 14 is fixed to the bottom end of the first limiting rod 15. When the slider 14 moves, it will drive the fixed first limiting rod 15 to move. The slider 14 is located inside the first limiting plate 5 and is slidably connected to the first limiting plate 5. A limiting plate is fixed to the surface of the slider 14. The limiting plate is located inside the first limiting plate 5 and is slidably connected to the first limiting plate 5. The limiting plate can restrict the position of the slider 14 and prevent the slider 14 from detaching from the inside of the first limiting plate 5. A second spring 16 is sleeved on the surface of the first limiting rod 15. One end of the second spring 16 contacts the inner surface of the first limiting plate 5, and the other end contacts the surface of the second limiting plate 17. When the second limiting plate 17 moves, it will compress the second spring 16, causing the second spring 16 to... When deformation occurs, the second spring 16 will push the second limiting plate 17 to move when there is no external force interference, thereby causing the second limiting plate 17 to drive the first limiting rod 15 to move. The fixing frame 7 is fixed to the surface of the second mold 2. Several sets of the fixing frame 7 are arranged and fixed around the surface of the second mold 2. The second limiting rod 18 is inserted inside the fixing frame 7. Two sets of the second limiting rod 18 are symmetrically inserted inside one set of fixing frames 7. The mounting block 12 is fixed to the top of the second limiting rod 18. The second limiting rod 18 can restrict the position of the mounting block 12 and prevent the mounting block 12 from detaching from the inside of the fixing frame 7.

[0023] The limiting claw 3, mounted on the surface of the mounting block 12, rotates via a pivot. When the mounting block 12 moves, it drives the rotatably connected limiting claw 3 to move. A first spring 6, sleeved on the surface of the second limiting rod 18, has one end fixed to the inner surface of the fixing frame 7 and the other end fixed to the surface of the mounting block 12. When the mounting block 12 moves, it stretches the first spring 6, causing it to deform. Without external interference, the first spring 6 pulls the mounting block 12 to move. The first gear 10 is rotatably mounted on the bottom of the fixing frame 7 via a support frame and pivot. The first gear 10 has an internal ratchet structure (not shown in the diagram). The second gear 11 is fixed... At one end of the shaft of the first gear 10, two sets of the first gear 10 are symmetrically arranged on both sides of a set of second gears 11. The fixing plate 8 is fixed to the surface of the first mold 1, and the first rack 9 is fixed to the surface of the fixing plate 8. Two sets of the first rack 9 are symmetrically fixed to the surface of the fixing plate 8. The first rack 9 is located on one side of the bottom of the first gear 10 and meshes with the first gear 10. When the fixing plate 8 moves to one side, it will drive the meshing first gear 10 to rotate, so that the first gear 10 drives the second gear 11 to rotate through the shaft. The second rack 13 is fixed to the bottom of the mounting block 12 and is located on top of the second gear 11. The first gear 10 is located on one side and meshes with the second gear 11. When the first gear 10 rotates to one side, it drives the second gear 11 to rotate via the shaft. This causes the second gear 11 to move the meshing second rack 13. When the second rack 13 moves, it drives the fixed mounting block 12 to move, which in turn drives the limiting pawl 3 to move. This allows one end of the limiting pawl 3 to pass between the two sets of mounting plates 4 and move to one side of the surface of the first mold 1. When the fixed plate 8 moves the first rack 9 to a certain position, the first rack 9 disengages from the first gear 10. At this time, the first spring 6 pulls the mounting block 12 to move. The mounting block 12 moves the limiting claw 3, causing one end of the limiting claw 3 to engage with the surface of the first mold 1 and pull the first mold 1 closer to the second mold 2, so that the surface of the first mold 1 is in close contact with the surface of the second mold 2. When the first mold 1 separates from the second mold 2 and moves the fixing plate 8 to the other side, the fixing plate 8 will move the first rack 9. At this time, the first rack 9 will re-engage with the first gear 10. However, because the first gear 10 has a ratchet structure inside, when the first rack 9 drives the first gear 10 to rotate, the first gear 10 will not drive the second gear 11 to rotate through the shaft.

[0024] Working principle: When it is necessary to close the first mold 1 and the second mold 2, the first mold 1 is moved to one side of the second mold 2 and the fixing plate 8 is inserted into the interior of the second mold 2. At this time, the fixing plate 8 will drive the first rack 9 to move and drive the second gear 11 to rotate through the first gear 10. The second gear 11 will drive the second rack 13 to move. When the second rack 13 moves, it will drive the mounting block 12 to move, and the mounting block 12 will drive the limiting claw 3 to move. One end of the limiting claw 3 will move to one side of the first mold 1. When the surfaces of the first mold 1 and the second mold 2 are in contact and the mold is closed, the first rack 9 will disengage from the second gear 11. At this time, the first spring 6 can pull the mounting block 12 to pull the limiting claw 3 to move, so that one end of the limiting claw 3 hooks onto the surface of the first mold 1. Thus, the limiting claw 3 pulls the first mold 1 to make the first mold 1 tightly adhere to the second mold. The surface of the mold 1 is fixed to one side of the second mold 2, making the installation and fixing efficiency of the mold relatively high and the use relatively convenient. When it is necessary to separate the first mold 1 from the second mold 2, the two sets of sliders 14 can be moved towards each other by pinching the slider 14, which will cause the slider 14 to drive the first limiting rod 15 to move. One end of the first limiting rod 15 will be moved out of the limiting hole opened inside the mounting plate 4. At this time, the first limiting plate 5 can be removed from the top side of the two sets of mounting plates 4. After the first limiting plate 5 is removed, the limiting claw 3 can be rotated around one end of the rotating shaft by tapping one end of the limiting claw 3, and the limiting claw 3 will be separated from the contact with the surface of the first mold 1. The first spring 6 will pull the limiting claw 3 through the mounting block 12 to move it, so that the limiting claw 3 moves closer to the second mold 2, thereby releasing the position restriction of the limiting claw 3 on the first mold 1 and the second mold 2. At this time, the first mold 1 and the second mold 2 can be separated.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
