[0028] A metal mold placement area 3 is symmetrically arranged on the top of the turntable 2. When the turntable 2 rotates, the position of the metal mold placement area 3 on the turntable 2 can be exchanged, so that the metal module to be processed can be transferred to the processing area, and the processed metal module can be transferred from the processing area, thereby improving the replacement efficiency of the metal mold.

[0029] The outer sides of the four sides of the metal mold placement area 3 are all provided with through holes 4, and a telescopic rod 5 is fixedly connected to the inner cavity of the fixed base 1, and a positioning structure is fixed on the top of the telescopic rod 5. Through the setting of the telescopic rod 5, the extension and retraction of the telescopic rod 5 can change the height of the positioning structure.

[0030] The positioning structure includes a support block 12 fixedly connected to the top of the telescopic rod 15, and a ball screw 19 and a ball screw 2 18 are movably connected to the support block 12, and the ball screw 19 and the ball screw 2 18 are in a mutually perpendicular state. A rotating motor 13 and a rotating motor 2 14 are fixed to the support block 12, and the end of the output shaft of the rotating motor 13 is fixedly connected to the end of the ball screw 19 through a reducer, and the end of the output shaft of the rotating motor 2 14 is fixedly connected to the end of the ball screw 2 18 through a reducer.

[0032] The outer ring of the ball screw 18 is threadedly connected to the ball nut 2, and the outer ring of the ball nut 2 is fixedly connected to the second moving rod 7, and another clamping plate structure is fixed at both ends of the top of the second moving rod 7. When the ball screw 18 rotates, the position of the second moving rod 7 on the ball screw 18 can change.

[0033] The clamping plate structure is adapted to the through hole 4. Under the action of the telescopic rod 1 5, the clamping plate structure can be moved to the top of the turntable 2 through the through hole 4. The clamping plate structure can be used to position, clamp and fix the metal mold placed on the metal mold placement area 3. When the clamping plate structure is located in the inner cavity of the turntable 2, the turntable 2 can rotate.

[0034] The clamping plate structure includes a fixed plate 15 and a movable plate 11. The bottom of the fixed plate 15 is connected to the first movable rod 6 or the second movable rod 7.

A first telescopic tube 23 is fixed in the inner cavity of the fixed plate 15. The other end of the first telescopic tube 23 is connected to the movable plate 11. Through the arrangement of the first telescopic tube 23, the telescopic rod 21 and the connecting rod 20, the contraction of the telescopic rod 21 can make the connecting rod 20 push the movable plate 11 away from the fixed plate 15. The extension of the telescopic rod 21 can make the connecting rod 20 pull the movable plate 11 close to the fixed plate 15. When the movable plate 11 is away from the fixed plate 15, the movable plate 11 can position and clamp the metal mold.

[0035] A buffer pad is fixedly connected to the side of the moving plate 11 away from the fixed plate 15, and the material of the buffer pad can be rubber. The first moving rod 6 and the second moving rod 7 are in a mutually perpendicular state. A pressure sensor is embedded on the side of the moving plate 11 away from the fixed plate 15, and the pressure sensor is used to detect the clamping force of the moving plate 11 on the metal mold in real time, so as to control the clamping force of the moving plate 11 on the metal mold.

[0036] The outer rings of the ball screw 19 and the outer rings of the ball screw 2 18 are both movably sleeved with a second telescopic tube 16, one end of the second telescopic tube 16 is fixedly connected to the support block 12, and the other end of the second telescopic tube 16 is fixedly connected to the first moving rod 6 or the second moving rod 7; an isolation tube 17 is fixed to the side of the first moving rod 6 away from the support block 12, and the ball screw 1 19 is located in the inner cavity of the isolation tube 17, and another isolation tube 17 is fixed to the side of the second moving rod 7 away from the support block 12, and the ball screw 2 18 is located in the inner cavity of the other isolation tube 17. By setting the second telescopic tube 16 and the isolation tube 17, it is possible to prevent the debris generated during the metal mold processing from falling on the ball screw 1 19 and the ball screw 2 18, so as to facilitate the change of the position of the splint structure. The material of the second telescopic tube 16 can be a corrugated tube.

[0037] The length of the through hole 4 is at least twice the length of the fixed plate 15. With this arrangement, the position of the fixed plate 15 in the through hole 4 can be changed, thereby exposing the portion of the metal mold blocked by the movable plate 11 during processing, making it convenient to process the portion blocked by the movable plate 11.

[0038] In some embodiments of the present application, the metal mold placement area 3 is a rectangular structure, the outer ring of the ball screw 19 is threadedly connected to two ball nuts 1, and a first moving rod 6 is fixed to the outer surface of each ball nut 1. There are two splint structures in the through hole 4 on the outer side of the long side of the metal mold placement area 3 to improve the stability of the metal mold clamping and fixing.

[0039] The telescopic rod 1 5 and the telescopic rod 2 21 mentioned above can both be hydraulic piston rods.

[0040] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0041] To sum up: when the positioning tool for metal mold processing is used, the metal mold to be processed is placed in the metal mold placement area 3, and the rotating motor 3 9 is started. The rotating motor 3 9 drives the gear 10 fixedly connected thereto to rotate, and the gear 10 rotates the turntable 2 through the gear ring 8 meshing therewith until the metal mold to be processed moves to the processing area.

[0042] The telescopic rod 1 5 is extended, and the telescopic rod 1 5 drives the positioning structure to move upward until the moving plate 11 in the clamping plate structure moves to the top of the turntable 2. At this time, the clamping plate structure in the positioning structure is distributed around the metal mold to be processed. The telescopic rod 2 21 is retracted, and the telescopic rod 21 drives the connecting rod 20 to move downward. The other end of the connecting rod 20 pushes the moving plate 11 outward, so that the moving plate 11 gradually approaches the metal mold until the moving plate 11 clamps and fixes the metal mold. The positioning structure realizes the clamping and fixing of the four sides of the metal mold.

[0043] During the metal mold processing process, the staff places another metal mold to be processed on the other metal mold placement area 3 on the turntable 2. When the metal mold in the processing area is processed, the telescopic rod 21 extends, and the telescopic rod 21 drives the connecting rod 20 to move upward. The other end of the connecting rod 20 pulls the movable plate 11 to move in the opposite direction until the movable plate 11 is reset. The positioning structure releases the positioning of the metal mold, and the telescopic rod 1 5 contracts, and the telescopic rod 1 5 drives the positioning structure to move downward until the positioning structure moves into the inner cavity of the turntable 2. The rotating motor 3 9 drives the turntable 2 to rotate, and the position of the metal mold to be processed and the processed metal mold are exchanged. During the clamping and positioning process of the metal mold to be processed, the staff takes and places the processed metal mold, thereby improving the metal mold processing efficiency.
