Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to a simple disassembly and assembly structure for mold inserts. Background Art

[0002] Mold inserts usually refer to the detachable and replaceable parts in a mold, which are used to form specific shapes and functions of the mold. The materials of the inserts are generally metal materials, and there are also non-metal materials such as glass and preformed plastic parts.

[0003] After the casting of the molded product is completed, it is usually necessary to remove the insert from the molded product. However, the commonly used insertion structure at present usually fixes the insert first and then uses external equipment to apply force to pull out the insert. This operation process is relatively cumbersome, which not only increases the working intensity but also reduces the disassembly and assembly efficiency. Therefore, it is necessary to design a simple disassembly and assembly structure for mold inserts that can quickly pull out the insert while fixing the insert. Content of the Utility Model

[0004] The utility model aims at the deficiencies of the existing technology and provides the following technical solution: a simple disassembly and assembly structure for mold inserts, including a disassembly and assembly main board. A communication round hole is opened at the center position of the top of the disassembly and assembly main board. A clamping mechanism for fixing the insert is rotatably connected to the outside of the communication round hole at the top of the disassembly and assembly main board. A driving motor is fixedly installed through a round hole on the outside of the clamping mechanism at the top of the disassembly and assembly main board. A driving gear is fixedly installed at the top of the driving motor, and the driving gear meshes with the clamping mechanism.

[0005] Pushing mechanisms for pulling out the insert are arranged on the left and right sides of the clamping mechanism at the top of the disassembly and assembly main board, and the clamping mechanism meshes with the pushing mechanisms.

[0006] As an improvement of the above technical solution, the clamping mechanism includes a rotating ring gear. The rotating ring gear is rotatably connected to the top of the disassembly and assembly main board and is located outside the communication round hole. The rotating ring gear meshes with the driving gear. A boosting inclined groove is opened between the communication round hole and the rotating ring gear on the top of the disassembly and assembly main board. A rotating ring plate is rotatably connected to the inner ring surface of the rotating ring gear. A pushing clamping groove is opened at the top of the rotating ring plate. A boosting inclined clamping block is movably clamped in the boosting inclined groove. A moving cylindrical clamping block is rotatably connected to the top of the boosting inclined clamping block. The moving cylindrical clamping block is movably clamped with the pushing clamping groove. A telescopic pushing plate is fixedly installed at the top of the moving cylindrical clamping block. A V-shaped clamping plate is fixedly installed at the end of the telescopic pushing plate close to the center of the circle. A circular ring friction clamping groove is opened at the top of the rotating ring plate. An arc friction clamping block is movably clamped in the circular ring friction clamping groove. One end of the arc friction clamping block far away from the circular ring friction clamping groove is installed on the top of the rotating ring gear. The insert is clamped and fixed through the cooperation of the clamping mechanisms.

[0007] As an improvement of the above technical solution, the pushing mechanism includes a driven ring gear, which is rotatably connected to the top of the disassembly and assembly main board and is located on the right side of the rotating ring gear. The driven ring gear meshes with the rotating ring gear. A through hole is opened on the top of the disassembly and assembly main board and inside the driven ring gear. A telescopic main cube barrel is fixedly installed at the bottom of the disassembly and assembly main board and outside the through hole. The telescopic main cube barrel is movably clamped with a telescopic pressing cube barrel. The inner ring surface of the driven ring gear is threadedly connected with a pressing threaded rod, and the bottom end of the pressing threaded rod is fixedly installed on the bottom inner wall of the telescopic pressing cube barrel. By the cooperation between the pushing mechanisms, the distance between the mold finished product and the disassembly and assembly main board is gradually increased, so as to pull out the insert through the clamping mechanism.

[0008] As an improvement of the above technical solution, a cube block is fixedly installed on the outer side of the movable cylindrical block, and the cube block is movably clamped with the pushing slot. When the assisting inclined block drives the telescopic pushing plate to move towards the center of the circle through the movable cylindrical block, the cube block makes the telescopic pushing plate move towards the position directly facing the center of the circle by being movably clamped with the pushing slot, preventing the telescopic pushing plate from deflecting during the moving process.

[0009] As an improvement of the above technical solution, a buffer spring is arranged inside the telescopic pushing plate, so that the V-shaped clamping plate has a certain buffer force when clamping the insert, preventing the V-shaped clamping plate from damaging the insert due to excessive clamping force.

[0010] The beneficial effects of the present utility model: The driving gear drives the clamping mechanism to clamp and fix the insert. At the same time, the clamping mechanism drives the pushing mechanism to relatively push the disassembly and assembly main board, so that the distance between the disassembly and assembly main board and the mold finished product gradually increases. With the mutual cooperation between the clamping mechanism and the pushing mechanism, after the mold insert disassembly and assembly structure clamps and fixes the insert, force can be applied to pull out the insert, simplifying the operation process and improving the disassembly and assembly efficiency of the insert.

Detailed implementation mode

[0016] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Refer to the attached Figure 1 , in Figure 1 , the a direction points to the front view and the b direction points to the right side view. The above views are only used to understand the solution.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a simple mold insert disassembly and assembly structure, including a disassembly and assembly main board 1. A connecting round hole 2 is opened at the center of the top of the disassembly and assembly main board 1. A clamping mechanism for fixing the insert is rotatably connected to the outside of the connecting round hole 2 at the top of the disassembly and assembly main board 1. A driving motor 5 is fixedly installed through a round hole on the outside of the clamping mechanism at the top of the disassembly and assembly main board 1. A driving gear 51 is fixedly installed at the top of the driving motor 5. The driving gear 51 meshes with the clamping mechanism;

[0019] Pushing mechanisms for pulling out the insert are arranged on the left and right sides of the clamping mechanism at the top of the disassembly and assembly main board 1. The clamping mechanism meshes with the pushing mechanism.

[0020] Specifically, the clamping mechanism includes a rotating ring gear 3. The rotating ring gear 3 is rotatably connected to the top of the disassembly and assembly main board 1 and is located outside the communication circular hole 2. The rotating ring gear 3 meshes with the driving gear 51. A boosting inclined groove 31 is formed at the top of the disassembly and assembly main board 1 and between the communication circular hole 2 and the rotating ring gear 3. The inner ring surface of the rotating ring gear 3 is rotatably connected to a rotating ring plate 32. A pushing clamping groove 33 is formed at the top of the rotating ring plate 32. The boosting inclined groove 31 is movably clamped with a boosting inclined clamping block 34. The top end of the boosting inclined clamping block 34 is rotatably connected to a moving cylindrical clamping block 35. The moving cylindrical clamping block 35 is movably clamped with the pushing clamping groove 33. The top end of the moving cylindrical clamping block 35 is fixedly installed with a telescopic pushing plate 36. One end of the telescopic pushing plate 36 close to the center of the circle is fixedly installed with a V-shaped clamping plate 37. A circular ring friction clamping groove 38 is formed at the top of the rotating ring plate 32. The circular ring friction clamping groove 38 is movably clamped with an arc friction clamping block 39. One end of the arc friction clamping block 39 far from the circular ring friction clamping groove 38 is installed on the top of the rotating ring gear 3.

[0021] In this embodiment, the insert is clamped and fixed through the cooperation between the clamping mechanisms.

[0022] Specifically, the pushing mechanism includes a driven ring gear 4. The driven ring gear 4 is rotatably connected to the top of the disassembly and assembly main board 1 and is located on the right side of the rotating ring gear 3. The driven ring gear 4 meshes with the rotating ring gear 3. A through circular hole is formed at the top of the disassembly and assembly main board 1 and inside the driven ring gear 4. A telescopic main cube cylinder 42 is fixedly installed at the bottom of the disassembly and assembly main board 1 and outside the through circular hole. The telescopic main cube cylinder 42 is movably clamped with a telescopic pressing cube cylinder 43. The inner ring surface of the driven ring gear 4 is threadedly connected with a pressing threaded rod 41. The bottom end of the pressing threaded rod 41 is fixedly installed on the bottom inner wall of the telescopic pressing cube cylinder 43.

[0023] In this embodiment, the distance between the mold finished product and the disassembly and assembly main board 1 is gradually increased through the cooperation between the pushing mechanisms, so as to pull out the insert through the clamping mechanism.

[0024] Specifically, a cube clamping block is fixedly installed on the outside of the moving cylindrical clamping block 35. The cube clamping block is movably clamped with the pushing clamping groove 33.

[0025] In this embodiment, when the boosting inclined clamping block 34 drives the telescopic pushing plate 36 to move towards the center of the circle through the moving cylindrical clamping block 35, the cube clamping block makes the telescopic pushing plate 36 move towards the position directly opposite to the center of the circle through the movable clamping with the pushing clamping groove 33, preventing the telescopic pushing plate 36 from deflecting during the moving process.

[0026] Specifically, a buffer spring is arranged inside the telescopic pushing plate 36.

[0027] In this embodiment, a certain buffering force is applied to the V-shaped clamping plate 37 when clamping the insert, preventing the V-shaped clamping plate 37 from damaging the insert due to excessive clamping force.

[0028] During use, the insert on the finished mold passes through the communication round hole 2, and the telescopic main cube cylinders 42 on both sides abut against the finished mold. The driving motor 5 is started, and the driving motor 5 drives the driving gear 51 to rotate counterclockwise. The driving gear 51 drives the rotating ring gear 3 to rotate clockwise through meshing with the rotating ring gear 3. The rotating ring gear 3 drives the arc friction block 39 to rotate. The arc friction block 39 drives the rotating ring plate 32 to rotate through the frictional force between the arc friction block 39 and the ring friction slot 38. The rotating ring plate 32 drives the pushing slot 33 to rotate. The pushing slot 33 drives the moving cylindrical block 35 to rotate. The moving cylindrical block 35 drives the assisting inclined block 34 to move along the assisting inclined slot 31. When the assisting inclined block 34 drives the telescopic pushing plate 36 to move through the moving cylindrical block 35, the cube block is movably clamped with the pushing slot 33, so that the telescopic pushing plate 36 moves towards the center position, preventing the telescopic pushing plate 36 from deflecting during the moving process. The telescopic pushing plate 36 drives the V-shaped clamping plate 37 to move towards the center position. Similarly, the working principle of the other V-shaped clamping plate 37 is the same as above. The insert is clamped and fixed by the two V-shaped clamping plates 37 moving synchronously towards the center position. At the same time, the rotating ring gear 3 drives the driven ring gear 4 to rotate. The driven ring gear 4 drives the pressing threaded rod 41 to move towards the position close to the finished mold under the restriction of the telescopic pressing cube cylinder 43 during rotation. The pressing threaded rod 41 drives the telescopic pressing cube cylinder 43 to extend towards the position close to the finished mold. The distance between the disassembly and assembly main board 1 and the finished mold is gradually increased by the pushing of the telescopic pressing cube cylinder 43 on the finished mold, so that the V-shaped clamping plate 37 gradually pulls out the insert. During the process of pulling out the insert, the rotating ring gear 3 drives the arc friction block 39 to continuously rotate, so that the arc friction block 39 continuously outputs a clamping force on the insert through the frictional force between the arc friction block 39 and the ring friction slot 38 and structures such as the rotating ring plate 32 and the V-shaped clamping plate 37. With the mutual cooperation between the clamping mechanism and the pushing mechanism, after the mold insert disassembly and assembly structure clamps and fixes the insert, a force can be applied to pull out the insert, simplifying the operation process and improving the disassembly and assembly efficiency of the insert.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
