[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 As shown, a plastic mold parts repair and positioning device includes: a worktable 1 and a base frame 7, and a clamping assembly 2 disposed on the upper surface of the worktable 1.

[0029] like Figures 2-3As shown, a fixed frame 6 is fixedly connected to the upper surface of the bottom frame 7, and a rotating plate 3 is rotatably connected between the bottom frame 7 and the fixed frame 6. The rotating plate 3 is fixedly connected to the outer circumference of the workbench 1.

[0030] A connecting block 9 is fixedly connected to the upper surface of the rotating plate 3. A through groove 8 is provided on the upper surface of the fixed frame 6. The connecting block 9 is located in the groove 8 and is slidably connected. A transmission plate 5 is fixedly connected to the top of the connecting block 9.

[0031] The upper surface of the rotating plate 3 is provided with several through grooves 4, and the upper surface of the bottom frame 7 is provided with a collection groove 10, with several grooves 4 located above the collection groove 10.

[0032] It should be noted that at the workbench 1 end, the rotating plate 3 is fixedly connected to its outer circumference and forms a rotatable connection with the bottom frame 7 and the fixed frame 6, enabling the workbench 1 to rotate relative to the bottom frame 7. This not only improves the flexibility and convenience of maintenance operations but also allows operators to adjust the angle and position of the workbench 1 according to the specific location of the parts and maintenance needs, thereby ensuring the smooth progress of the maintenance process. Simultaneously, at the workbench 1 end, several through-grooves 4 on the rotating plate 3, combined with the collection groove 10 on the upper surface of the bottom frame 7, effectively solve the problems of debris and waste generated during maintenance.

[0033] like Figures 2-3 As shown, the clamping assembly 2 includes: a bidirectional threaded rod 201, two guide blocks 203 disposed on the outer circumference of the bidirectional threaded rod 201, a fixing plate 205 disposed on the outer circumference of the worktable 1, a motor 207 disposed on one side of the fixing plate 205, and two clamping blocks 204 disposed on the outer circumference of the two guide blocks 203 respectively.

[0034] The two ends of the bidirectional threaded rod 201 are rotatably connected to the inner circumference of the worktable 1. The fixed plate 205 is fixedly connected to the outer circumference of the worktable 1. The motor 207 is fixedly connected to one side of the fixed plate 205. One end of the output shaft of the motor 207 passes through the fixed plate 205 and the worktable 1 and is fixedly connected to one end of the bidirectional threaded rod 201.

[0035] Two guide blocks 203 are threadedly connected to the outer circumferential wall of the bidirectional threaded rod 201. Two guide grooves 202 are provided on the upper surface of the worktable 1. Two clamping blocks 204 are respectively located in the two clamping blocks 204 and are slidably connected. The bottom of the two clamping blocks 204 is respectively fixedly connected to the outer circumferential wall of the two guide blocks 203.

[0036] A protective shell 206 is fixedly connected to one side of the fixed plate 205. The motor 207 is located inside the protective shell 206. Several through heat dissipation slots 208 are opened on the outer circumference of the protective shell 206.

[0037] It should be noted that the clamping assembly 2 utilizes a bidirectional threaded rod 201, guide blocks 203, a fixing plate 205, a motor 207, and clamping blocks 204 to clamp the plastic mold parts. The two ends of the bidirectional threaded rod 201 are rotatably connected to the inner circumference of the worktable 1, ensuring its stability and reliability during rotation. The motor 207 is securely mounted on the worktable 1 via the fixing plate 205, and its output shaft is directly connected to one end of the bidirectional threaded rod 201, thereby driving its rotation. Two guide blocks 203 are threadedly connected to the outer circumference of the bidirectional threaded rod 201, allowing them to move towards or away from each other along the thread direction when the bidirectional threaded rod 201 rotates. Simultaneously, two guide grooves 202 on the upper surface of the worktable 1 provide a sliding path for the clamping blocks 204, ensuring their stability during movement. The protective housing 206 provides protection for the motor 207, while the heat dissipation slot 208 ensures the heat dissipation needs of the motor 207 during operation.

[0038] In use, the motor 207 is first started, and its output shaft begins to rotate. The output shaft of the motor 207 is fixedly connected to one end of the bidirectional threaded rod 201. Therefore, the rotation of the motor 207's output shaft causes the bidirectional threaded rod 201 to rotate within the inner circumference of the worktable 1. As the bidirectional threaded rod 201 rotates, the two guide blocks 203 move towards or away from each other along the thread direction due to the threaded action. The guide blocks 203 drive the clamping blocks 204 to slide within the guide groove 202. When the guide blocks 203 move, the clamping blocks 204 also move accordingly. As the guide blocks 203 move towards each other, the two clamping blocks 204 gradually approach each other and eventually clamp the plastic mold part. After clamping the part, the operator can adjust the angle and position of the worktable 1 by rotating the transmission plate 5. The transmission plate 5 is fixedly connected to the rotating plate 3 via the connecting block 9, and the rotating plate 3 is rotatably connected to the bottom frame 7 and the fixed frame 6. Therefore, when the transmission plate 5 is subjected to external force, it will drive the rotating plate 3 and the worktable 1 fixedly connected to it to rotate together. In addition, some debris and waste will be generated during the maintenance process. These debris and waste can fall into the collection groove 10 on the upper surface of the bottom frame 7 through several through slots 4 opened on the rotating plate 3.

[0039] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
