Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically a tooling and fixture for casting molds. Background Technology

[0002] A casting mold is a tool used to create a part's structural shape. This shape is first formed from a readily formable material, then placed inside a sand mold, creating a cavity with dimensions identical to the part's structure. A fluid liquid is then poured into this cavity, and after cooling and solidifying, a part with the exact same shape and structure as the mold is formed. During use, the casting mold needs to be positioned and clamped to facilitate the pouring of the fluid. Generally, different shapes of metal castings can be obtained by changing the shape of the casting mold during the production process.

[0003] Existing traditional mold tooling fixtures typically rely on manual rotation of a screw to control the clamping blocks to hold the mold in place. This not only requires manual rotation but also necessitates further manual intervention. Furthermore, when removing the casting mold from the worktable, the operator must rotate the screw again to move the clamping blocks and release the mold. Therefore, mold removal and replacement involve multiple steps, hindering efficient operation. To address these issues, we provide a casting mold tooling fixture. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a casting mold tooling fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casting mold tooling fixture, including a worktable, on which two opposing movable frames are slidably arranged. The bottom of the worktable is provided with a displacement mechanism for driving the two movable frames to move relative to each other. Each movable frame has a slot plate fixedly connected to its inner wall. Each slot plate is fitted with two opposing sleeves. Each sleeve is fixedly connected with a fixing block. Each fixing block is provided with a clamping block mechanism. Each sleeve is provided with a limit mechanism.

[0006] Preferably, the clamping block mechanism includes a cylinder and a clamping block. The cylinder is mounted on the surface of the fixed block, the clamping block is slidably disposed on the inner wall of the fixed block, a positioning rod is fixedly connected to the inner wall of the clamping block, and the telescopic end of the cylinder is sleeved on the positioning rod.

[0007] Preferably, the inner wall of the fixing block is fixedly connected to an inclined plate, the surface of the clamping block is provided with an inclined groove, and the clamping block slides on the inclined plate through the inclined groove. The upper and lower surfaces of the fixing block are provided with slots, and the clamping block is fitted into the two slots on the fixing block.

[0008] Preferably, the limiting mechanism includes a guide rod and a locking plate. The guide rod is disposed through the sleeve frame, and the locking plate is slidably disposed above the sleeve frame and locked onto the slot plate. The bottom end of the guide rod is connected to the locking plate. A fixing plate is fixedly connected to the surface of the guide rod and is sleeved on the surface of the guide rod. A tension spring is fixedly connected to the bottom surface of the fixing plate and the bottom end of the tension spring is fixedly connected to the sleeve frame.

[0009] Preferably, the displacement mechanism includes a guide groove and a motor. The guide groove is formed on the worktable, and the two bottom ends of the two moving frames slide within the guide groove. The motor is mounted on the side of the worktable, and the output end of the motor is fixedly connected to a bidirectional lead screw. Two opposing moving plates are threaded onto the bidirectional lead screw, and the two moving frames are respectively connected to the two moving plates.

[0010] Preferably, there are two guide grooves, and the two bottom ends of the moving frame slide in the two guide grooves respectively. The two bottom ends of the two moving frames are detachably connected to the two ends of the two moving plates respectively by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, through the coordinated arrangement of two moving frames, a displacement mechanism, a slotted plate, a sleeve frame, a fixed block, a clamping block mechanism, and a limiting mechanism, allows two casting molds to be placed between two moving frames. The corresponding sleeve frames are slid closer together, positioning two clamping blocks on either side of the mold. A cylinder then pushes the clamping blocks to slide on the fixed block, causing the two clamping blocks to clamp and fix the mold at an angle. When the two molds need to be squeezed together, a motor rotates a bidirectional lead screw, causing the two moving frames to move relative to each other, bringing the molds closer together. Casting can then begin. After casting is complete, the motor is reversed, causing the two molds to move away from each other along with the moving frames, allowing the casting to be removed. When mold replacement is needed, simply pull the guide rod upwards and slide the sleeve frame away from the center of the moving frame to easily remove the mold, eliminating the need for cumbersome steps.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-8As shown, this embodiment proposes a casting mold tooling fixture, including a worktable 1. Two opposing movable frames 3 are slidably arranged on the worktable 1, allowing two molds to be fixed on the two movable frames 3 respectively. The two molds can be brought closer together by the subsequent movement of the two movable frames 3. A displacement mechanism is provided at the bottom of the worktable 1 to drive the two movable frames 3 to move relative to each other. The displacement mechanism enables the two movable frames 3 to move away from or towards each other. Since the displacement mechanism is located at the bottom of the worktable 1, it does not obstruct personnel working on the worktable 1. A slotted plate 7 is fixedly connected to the inner wall of each movable frame 3. Two opposing slots are formed on the upper surface of the slotted plate 7, and two opposing sleeves 10 are fitted on each slotted plate 7, allowing the two molds to move closer together. Each sleeve frame 10 can slide on the slot plate 7. Each sleeve frame 10 is fixedly connected to a fixing block 4. The inner wall of the fixing block 4 is inclined. Each fixing block 4 is provided with a clamping mechanism. The mold can be placed between two fixing blocks 4 through the clamping mechanism, and finally clamped and fixed by the clamping mechanism. This can adapt to the fixing of molds of different sizes. Each sleeve frame 10 is provided with a limit mechanism. The limit mechanism can prevent the sleeve frame 10 from moving randomly on the slot plate 7, thereby ensuring the stability of the mold after fixing. It can also adjust the distance between the two sleeve frames 10 according to the mold size. The machinery, parts and equipment in this device all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] like Figures 1 to 3 and Figures 5 to 7 As shown, the clamping mechanism includes a cylinder 5 and a clamping block 6. The cylinder 5 is mounted on the surface of the fixed block 4, and the clamping block 6 is slidably disposed on the inner wall of the fixed block 4. A positioning rod 16 is fixedly connected to the inner wall of the clamping block 6. The telescopic end of the cylinder 5 is sleeved on the positioning rod 16. With the above structure, after the mold is placed on the worktable 1, the two guide rods 9 are slid closer to each other, so that the two clamping blocks 6 are on both sides of the mold, and the mold is in close contact with the surface of the moving frame 3. Then, the operation of the two cylinders 5 pushes the clamping blocks 6 to slide on the fixed block 4, thereby realizing the squeezing and clamping of the mold by the two clamping blocks 6. This makes the clamping and fixing of the mold more convenient and flexible to use, without cumbersome steps, and also facilitates quick mold replacement. When the two molds are close together, the two adjacent cylinders 5 will not contact each other, and the thickness of the casting mold used is greater than the distance between the moving frame 3 and the cylinder 5.

[0025] like Figure 3 , Figures 5 to 7As shown, the inner wall of the fixing block 4 is fixed with an inclined plate 18, and the surface of the clamping block 6 is provided with an inclined groove 17. The clamping block 6 slides on the inclined plate 18 through the inclined groove 17. The upper and lower surfaces of the fixing block 4 are provided with slots, and the clamping block 6 is fitted into the two slots on the fixing block 4. With the above structure, the clamping block 6 can slide on the inclined plate 18 on the fixing block 4 through the inclined groove 17, so that the sliding trajectory of the clamping block 6 is inclined, thereby improving the clamping force of the clamping block 6 on the mold.

[0026] like Figure 1 , Figures 3 to 5 and Figure 8 As shown, the limiting mechanism includes a guide rod 9 and a locking plate 15. The guide rod 9 is disposed through the sleeve frame 10. The locking plate 15 is slidably disposed above the sleeve frame 10 and is engaged with the locking slot plate 7. The bottom end of the guide rod 9 is connected to the locking plate 15. A fixing plate 14 is fixedly connected to the surface of the guide rod 9 and is sleeved on the surface of the guide rod 9. A tension spring 13 is fixedly connected to the bottom surface of the fixing plate 14 and the bottom end of the tension spring 13 is fixedly connected to the sleeve frame 10. With the above structure, two sleeves can slide. When the frames 10 move closer to each other, and conversely when the sleeve frame 10 moves away from the center of the moving frame 3, the sleeve frame 10 will not move on its own because the clamping plate 15 is engaged with the slot plate 7. Only after pulling the guide rod 9 upwards can the clamping plate 15 release the sleeve frame 10 from the slot plate 7, and the sleeve frame 10 can be moved away from the center of the moving frame 3. This ensures the stability of the clamping block 6 in clamping the mold, prevents the sleeve frame 10 from sliding arbitrarily, and ensures that the sleeve frame 10 is not obstructed or limited when it moves closer to the center of the moving frame 3.

[0027] like Figure 1 and Figure 2 As shown, the displacement mechanism includes a guide groove 2 and a motor 8. The guide groove 2 is opened on the worktable 1. The two bottom ends of the two moving frames 3 slide in the guide groove 2. The motor 8 is installed on the side of the worktable 1. The output end of the motor 8 is fixedly connected to a bidirectional lead screw 11. Two opposing moving plates 12 are threaded onto the bidirectional lead screw 11. The two moving frames 3 are respectively connected to the two moving plates 12. With the above structure, the two moving frames 3 can move relative to each other on the worktable 1. In specific operation, the motor 8 is used to drive the bidirectional lead screw 11 to rotate, thereby causing the two moving frames 3 to move relative to each other, realizing the two moving frames 3 moving closer or further apart. When the two casting molds are placed on the worktable 1, the two moving frames 3 can be used to squeeze the two molds closer together, which facilitates the subsequent pouring of the casting liquid between the two molds.

[0028] like Figure 1 and Figure 2As shown, there are two guide grooves 2, and the two bottom ends of the moving frame 3 slide in the two guide grooves 2 respectively. The two bottom ends of the two moving frames 3 are detachably connected to the two ends of the two moving plates 12 by bolts. With the above structure, the stability of the moving frame 3 on the worktable 1 can be guaranteed, effectively preventing the worktable 1 from tilting. The moving frame 3 can be easily removed from the worktable 1. In specific operation, the bolts at both ends of the moving plate 12 can be removed directly from the worktable 1, which is conducive to the subsequent maintenance and replacement of the moving frame 3 and improves the practicality of the device.

[0029] The working principle and usage process of this utility model are as follows: First, place the two casting molds on the adjacent sides of the two moving frames 3 respectively. Then, slide the two sleeve frames 10 on the moving frames 3 closer to each other, so that the two clamping blocks 6 are on both sides of the mold. Then, use the operation of the cylinder 5 to push the clamping blocks 6 to slide on the fixed block 4, so that the two clamping blocks 6 clamp and fix the mold in an inclined manner. When it is necessary to squeeze the two molds together, simply use the operation of the motor 8 to drive the bidirectional lead screw 11 to rotate, so that the two moving frames 3 move relative to each other, thus bringing the two molds closer. Then, pour the casting liquid between the two molds. After the pouring is completed, control the motor 8 to rotate in the opposite direction, so that the two molds move away from each other with the two moving frames 3, and the casting can be removed. When it is necessary to replace the mold, simply pull the guide rod 9 upward and slide the sleeve frame 10 away from the middle of the moving frame 3 to easily remove the mold without complicated steps.
