[0003] Existing clamping devices have a complex and unreasonable structure. In actual use, they are directly clamped on both sides of the mold base. After long-term use, the clamping plates will deform, resulting in insufficient tightness between the mold base and the clamping plates and unstable mold base fixation. To address this problem, the inventors designed a clamping device for mold base processing. Utility Model Content

[0026] The clamping assembly 3 includes a connecting frame 34, a silicone pad 35, and a limiting frame 36. The silicone pad 35 is disposed inside both ends of the connecting frame 34. There are two sets of connecting frames 34, which are distributed on both sides of the mold base body 1. The inner surface of the silicone pad 35 is in contact with the four corner surfaces of the mold base body 1. The limiting frame 36 is fixed in the middle of the upper surface of any set of connecting frames 34. The limiting frame 36 includes a fixing part 361 and a limiting part 362. The fixing part 361 and the limiting part 362 are integrally formed. The bottom surface of the fixing part 361 is fixed to the top surface of the connecting frame 34. The cross-section of the limiting part 362 is a right trapezoidal shape, and the limiting part 362 is inserted into the interior of the mold base body 1.

[0027] The mold base body 1 is the base of the mold and is used to move the entire mold to the required position. The connecting frame 34 is used to clamp the outside of the four corners of the mold base body 1, thereby completing the lateral fixation of the mold base body 1. The silicone pad 35 is attached to the four corners of the mold base body 1 to protect the surface from scratches and at the same time provide friction to prevent the mold base body 1 from sliding. The fixing part 361 is fixed on the connecting frame 34 to ensure the stability of the limiting frame 36. The limiting part 362 is inserted into the mold base to limit the horizontal displacement of the mold base and enhance the positioning accuracy.

[0028] A connecting post 33 is fixed to the outer surface of the connecting frame 34, and a movable post 32 is fixed to the lower surface of the connecting post 33;

[0029] The connecting column 33 is used to support and install the connecting frame 34, and then to support and install the movable column 32. The movable column 32 is used to transmit the driving force of the ball screw 311, so that the connecting column 33 can move horizontally.

[0030] The movable column 32 has a nut for the ball screw 311 inside, and the output end of the stepper motor 31 is located on the inner side of the ball screw 311.

[0031] The stepper motor 31 is the drive source for the ball screw 311, which in turn controls the movable column 32 to move horizontally.

[0032] The connecting bracket 34 and the silicone pad 35 are internally connected by screws 37;

[0033] Screw 37 is used to securely fix the silicone pad 35 to the surface of the connector 34;

[0034] The support assembly 2 includes a first support plate 21, a second support plate 22, a mounting hole 23, and a through hole 24; the second support plate 22 is attached to the top of the first support plate 21, the mounting hole 23 is opened in the middle of the first support plate 21, and the through hole 24 is opened in the middle of the second support plate 22, with the mounting hole 23 and the through hole 24 having the same diameter.

[0035] The first support plate 21 and the second support plate 22 cooperate to form a stable support structure, providing a basic positioning for the mold base. The mounting hole 23 is used to receive and install the spring 28, and the through hole 24 allows the support column 27 to move vertically inside the second support plate 22.

[0036] Square slots 25 are provided on both sides of the first support plate 21 and the second support plate 22, and the interior of the square slots 25 is connected to the stepper motor 31.

[0038] A hydraulic cylinder 26 is provided on the lower surface of the first support plate 21. A support column 27 is provided at the output end of the hydraulic cylinder 26. The support column 27 is inserted into the bottom end of the mold base body 1. A spring 28 is fixed inside the mounting hole 23, and the top of the spring 28 is connected to the bottom of the support column 27.

[0039] Hydraulic cylinder 26 drives support column 27 to rise and fall, quickly adjusting the height of mold base. Support column 27 is used to position the mold base to the required position. Spring 28 buffers the reset action of support column 27 to avoid rigid impact.

[0040] Working principle: When it is necessary to fix the mold base body 1 in the required position, firstly, the hydraulic cylinder 26 is started, which drives the support column 27 to move upward and move away from the inside of the second support plate 22. Under the guidance of the support column 27, the mold base body 1 is placed on the top of the support column 27. Then, the hydraulic cylinder 26 drives the support column 27 to move downward, so that the mold base body 1 is in contact with the surface of the second support plate 22. Then, the stepper motor 31 is started, the ball screw 311 is in a rotating state, the movable column 32 moves horizontally, and drives the connecting column 33 to move to one side of the mold base body 1. When the silicone pad 35 is in contact with the surface of the mold base body 1, the limiting part 362 of the limiting frame 36 is simultaneously inserted into the mold base body 1.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
