[0018] The following is combined with Figure 1 - Figure 3 This application is described in further detail.

[0019] Reference Figure 1 - Figure 3, a clamping tool for manufacturing special-shaped molds, including a base 1, a lifting platform 2 that can move up and down is provided between the upper end of the base 1 and the clamping component, the lifting platform 2 can play a reliable supporting role in the process of clamping and removing the mold, without the need for external lifting equipment, and does not affect the normal operation of the clamping equipment. A horizontally movable placement plate 3 is provided on the lifting platform 2, the placement plate 3 is located in the middle position of the clamping component on the base 1, the placement plate 3 can adjust the position between the placement plate 3 and the clamping component according to the mold placement position, under the action of the mold, the placement plate 3 can cooperate with the left and right clamping actions of the clamping component, so that the mold can be more easily positioned in the middle position of the fixture, without the need to manually move and adjust the mold on the placement plate 3, and at the same time has an automatic reset function, a through groove is provided in the center of the lifting platform 2, and a movable groove 6 is also provided in the through groove, and a movable disk 7 is slidably arranged inside the movable groove 6, a connecting column 8 is vertically fixed to the bottom of the placement plate 3, the connecting column 8 is fixedly installed with the movable disk 7, and a conical groove 9 located at the bottom of the lifting platform 2 is also fixed at the bottom of the connecting column 8, and also includes a contact ball 10 that cooperates with the conical groove 9.

[0020] Reference Figure 1 - Figure 2 A telescopic frame 4 is slidably provided between the lifting platform 2 and the base 1. A telescopic motor 5 is installed at one end of the telescopic frame 4 close to the base 1. The lifting platform 2 drives the telescopic frame 4 to move up and down in the base 1 through the telescopic motor 5. The bottom of the telescopic frame 4 is divided into two ends, one end is used as an active end through a screw rod and a screw sleeve in conjunction with the telescopic motor 5, and the other end is used as a driven end through a guide rod and a guide sleeve to ensure the reliable lifting of the lifting platform 2.

[0021] Reference Figure 3 The contact ball 10 is always in contact with the inner side of the conical groove 9, a telescopic rod 11 is fixed on the contact ball 10, a bottom plate 12 is fixed parallel to the bottom of the lifting platform 2, and there is only one central vertex of the conical setting, but it can move in any direction in the horizontal position, with high flexibility, and the mold can be quickly and conveniently adjusted to the clamping position.

[0022] Reference Figure 3 The telescopic rod 11 vertically penetrates the bottom plate 12, and a reset spring 13 is provided between the portion of the telescopic rod 11 that penetrates the bottom plate 12 and the portion of the telescopic rod 11. The reset spring 13 is used for resetting between the conical groove 9 and the contact ball 10 so as to be used again.

[0023] Reference Figure 2 - Figure 3 The movable groove 6 and the movable plate 7 are both circular structures. The through groove of the base 1 has a movable space for the connecting column 8, and the movable groove 6 has a movable space for the movable plate 7. The circular structure increases the radius of the horizontal movement of the placement plate 3 and has high flexibility.

[0024] Reference Figure 3A ball 14 is provided at the bottom of the placement plate 3, and the bottom of the ball 14 also rolls on the lifting platform 2. The ball 14 ensures the flexibility of the placement plate 3 and facilitates the synchronous movement of the mold and the placement plate 3.

[0025] Working principle: when the mold needs to be clamped, the mold is placed on the upper end of the placement plate 3, and the telescopic frame 4 is driven by the telescopic motor 5 to move the lifting platform 2 upward. During the movement of the lifting platform 2, the mold is lifted upward. After the mold is lifted to a suitable position, the clamping component on the base 1 performs the clamping work. Since the mold is placed manually on the placement plate 3, the accuracy cannot be guaranteed. In order to ensure the clamping stability, the staff can move the placement plate 3 and the mold on the lifting platform 2 synchronously. During the movement, the movable plate 7 slides inside the movable groove 6, and the ball 14 rolls on the lifting platform 2. Due to the change in position, the telescopic rod 11 will vertically extend and retract under the cooperation of the conical groove 9 and the contact ball 10. At this time, the reset spring 13 will also deform until the clamping component on the base 1 completely clamps the mold. After the lifting platform 2 is moved down, the placement plate 3 is not affected by external forces. Under the cooperation of the conical groove 9, the contact ball 10, and the reset spring 13, the placement plate 3 is reset to the original position, and the contact ball 10 is located at the top of the conical groove 9. The lifting platform 2 moves down to the bottom, and then the mold processing and manufacturing work is carried out;

[0026] When the mold needs to be removed after processing is completed, the lifting platform 2 is lifted upward and the placement plate 3 is supported on the bottom of the mold, the clamping parts on the base 1 are released, the mold falls on the placement plate 3, the lifting platform 2 is lowered, and finally the processed mold can be removed.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
