[0024] An extrusion device is mounted on the top surface of the bottom plate 1 and directly above the mold seat 3 through an installation bracket. A plurality of rollers distributed left and right are rotatably connected between the front and rear inner walls of the U-shaped plate 2 and close to the bottom surface.

[0025] See also Figure 1-2The fixing mechanism includes a connecting bin 501 fixed to the right end of the output shaft of the cylinder 4, two telescopic rods 502 are fixed on the inner top wall of the connecting bin 501, and a limit plate 503 is fixed to the bottom ends of the two telescopic rods 502. A spring 504 is sleeved on the outer peripheral wall of the telescopic rod 502. A limit bolt 505 is threadedly connected to the top surface of the connecting bin 501. A connecting plate 506 whose left end extends to the inside of the connecting bin 501 is fixed on the left side of the mold base 3. A limit rod 507 is fixed on the inner bottom wall of the connecting bin 501, and a limit rod 507 is inserted into the top surface of the connecting plate 506. When the mold base 3 needs to be disassembled for replacement, lift the mold base 3 upwards to drive the connecting plate 506 to move upward inside the connecting bin 501, further disengaging the limiting hole 508 from the limiting rod 507. At this time, the cylinder 4 can be retracted to drive the connecting bin 501 to move to the left and then disengage from the connecting plate 506 for disassembly. When fixing, reverse the above operation, and use the spring 504 to cooperate with the telescopic rod 502 to make the limiting plate 503 abut against the top surface of the connecting plate 506, and then turn the limiting bolt 505 to limit the upward and downward movement of the limiting plate 503 to complete the installation.

[0026] The right side of the connecting bin 501 is open, and a limiting bolt 505 is arranged between the two telescopic rods 502. A threaded hole is provided on the top surface of the connecting bin 501 for the limiting bolt 505 to pass through and be threadedly connected thereto. The connecting bin 501 is used for the connecting plate 506 to slide up and down inside it with a clearance fit between the two, and the limiting rod 507 is clearance fit between the limiting hole 508.

[0027] See also Figure 1-4In this embodiment, the positioning mechanism includes two circular rods 601 respectively fixed on the front and rear sides of the mold base 3, the top surface of the U-shaped plate 2 is provided with two rectangular grooves 602 distributed front and back, a rectangular bin 603 is fixed on the right inner wall of the rectangular groove 602, a plurality of connecting rods 604 are slidably connected to the bottom surface of the rectangular bin 603, a positioning plate 605 is fixed to the bottom ends of the plurality of connecting rods 604, a plurality of positioning grooves 606 are provided on the top surface of the U-shaped plate 2 and located in the rectangular groove 602, a trapezoidal block 607 is fixed to the top end of the connecting rod 604, a screw 608 whose left end extends into the inside is rotatably connected to the right side of the rectangular bin 603, a plurality of extrusion blocks 609 are threadedly connected to the outer peripheral wall of the screw 608, a slider 610 slidably connected to the rectangular bin 603 is fixed to the top surface of the extrusion block 609, and the rectangular bin 6 A slide groove 611 for sliding connection of the slider 610 is provided on the inner top wall of 03. When adjusting the mold base 3 to move left and right, rotate the screw 608, and the screw 608 drives the extrusion block 609 to cooperate with the slide groove 611 and the slider 610 to slide to the right, so that the extrusion block 609 is separated from the trapezoidal block 607. At this time, the positioning plate 605 and the connecting rod 604 can slide up and down, and then start the cylinder 4 to drive the mold base 3 to move left and right for adjustment. During movement, the mold base 3 will drive the circular rod 601 to slide inside the rectangular groove 602. After adjustment, the circular rod 601 will slide into the corresponding positioning groove 606, and then reverse the screw 608 to make the extrusion block 609 squeeze the trapezoidal block 607, so that the positioning plate 605 cannot move up and down, and cooperate with the positioning groove 606 to position the circular rod 601 and the mold base 3.

[0028] It should be understood that when adjusting the mold base 3, the circular rod 601 on the mold base 3 will produce an up and down displacement when sliding in and out of the positioning groove 606. At this time, the limitation of the limiting bolt 505 will not cause the limiting hole 508 on the connecting plate 506 to be completely separated from the limiting rod 507, thereby ensuring the stability of the adjustment.

[0029] The two circular rods 601 extend into the two rectangular grooves 602 respectively. The bottom surface of the rectangular bin 603 is provided with a sliding hole for the connecting rod 604 to vertically penetrate and slideably connect with it. A handle is fixed to the right end of the screw rod 608. Multiple positioning grooves 606 are evenly distributed on the left and right. The positioning grooves 606 are arc-shaped grooves. The sliding groove 611 is used for the slider 610 to slide left and right inside it.

[0030] The working principle of the above embodiment is:

[0031] (1) When the mold base 3 needs to be disassembled for replacement, the mold base 3 is lifted upward to drive the connecting plate 506 to move upward inside the connecting chamber 501, further disengaging the limiting hole 508 from the limiting rod 507. At this time, the cylinder 4 can be retracted to drive the connecting chamber 501 to move to the left and then disengage from the connecting plate 506 for disassembly. When fixing, the above operation is reversed, and the limiting plate 503 is abutted against the top surface of the connecting plate 506 through the spring 504 and the telescopic rod 502, and then the limiting bolt 505 is turned to limit the upward and downward movement of the limiting plate 503 to complete the installation.

[0032] (2) When adjusting the mold base 3 to move left and right, rotate the screw 608, and the screw 608 drives the extrusion block 609 to cooperate with the slide groove 611 and the slider 610 to slide to the right, so that the extrusion block 609 is separated from the trapezoidal block 607. At this time, the positioning plate 605 and the connecting rod 604 can slide up and down, and then start the cylinder 4 to drive the mold base 3 to move left and right for adjustment. During the movement, the mold base 3 will drive the round rod 601 to slide inside the rectangular groove 602. After adjustment, the round rod 601 will slide into the corresponding positioning groove 606, and then reverse the screw 608 to make the extrusion block 609 squeeze the trapezoidal block 607, so that the positioning plate 605 cannot move up and down, and cooperate with the positioning groove 606 to position the round rod 601 and the mold base 3.
