[0006] An elastic element is provided between the upper and lower pressure plates. When the upper mold base assembly moves upward, the upper pressure plate resets upward under the elastic force of the elastic element.

[0007] The upper mold base assembly includes an upper mold base and a pressure block. The pressure block is fixed to the bottom of the upper mold base. When the upper mold base assembly moves downward to the corresponding position, the pressure block presses down on the upper pressure plate to push the upper pressure plate downward.

[0008] The lower mold base assembly includes a lower mold base and a guide post, with the guide post fixed on the lower mold base. The upper mold base assembly also includes a guide sleeve, which is fixed on the upper mold base. When the upper mold base assembly moves up and down, the guide sleeve moves up and down along the guide post.

[0009] The upper pressure plate is provided with a first fixing hole, the lower pressure plate is provided with a second fixing hole, and the lower mold base is provided with a third fixing hole. Fasteners pass through the first fixing hole and the second fixing hole in sequence and are then fastened to the third fixing hole, so that the upper pressure plate and the lower pressure plate are movably connected and the lower pressure plate is fixed on the lower mold base.

[0010] The fastener is equipped with a limit head, which acts on the limit head when the upper pressure plate moves upward to reset.

[0027] The upper pressure plate 3 is provided with a first fixing hole 12, the lower pressure plate 4 is provided with a second fixing hole 13, and the lower mold base 9 is provided with a third fixing hole 14. The fastener 15 (long screw) passes through the first fixing hole 12 and the second fixing hole 13 in sequence and is then fastened to the third fixing hole 14, so that the upper pressure plate 3 and the lower pressure plate 4 are connected to move up and down and the lower pressure plate 4 is fixed on the lower mold base 9.

[0028] The fastener 15 is provided with a limit head 16. When the upper pressure plate 3 moves upward to reset, it acts on the limit head 16, thereby limiting the upper pressure plate 3 and preventing the upper pressure plate 3 from moving upward excessively; the limit head 16 is a screw head.

[0029] The elastic element 6 is sleeved on the fastener 15. When the upper pressure plate 3 moves downward, the elastic element 6 compresses and stores energy. When the pressure block 8 is separated from the upper pressure plate 3, the elastic element 6 releases the stored energy so that the upper pressure plate 3 can move upward.

[0030] The upper pressure plate 3 moves up and down along the fastener 15 through the first fixing hole 12, thereby guiding the up and down movement of the upper pressure plate 3 and preventing the upper pressure plate 3 from shifting when moving up and down.

[0031] The upper pressure plate 3 is the upper pressure iron, and the lower pressure plate 4 is the lower pressure iron.

[0032] The upper pressure plate 3 has a protruding lower pressure part 17 at one end, and the lower pressure plate 4 has a protruding mating pressure part 18 at one end. When the upper pressure plate 3 moves downward, the lower pressure part 17 and the mating pressure part 18 cooperate with each other to flatten the end 22 of the shaft 5. The lower pressure part 17 and the mating pressure part 18 can provide greater pressure, so that the flattening effect of the shaft 5 is better.

[0033] A first clearance position 20 for the clearance movement wheel 19 is formed on one side of the lower pressure part 17, and a second clearance position 21 for the clearance movement wheel 19 is formed on one side of the mating pressure part 18. The first clearance position 20 can prevent the upper pressure plate 3 from interfering with the movement wheel 19, and the second clearance position 21 can prevent the lower pressure plate 4 from interfering with the movement wheel 19.

[0034] The movable wheel 19 is a pulley, and the axle 5 is the pulley shaft.

[0035] The refrigerator compressor compartment has a first lug 26 and a second lug 27 on its bottom plate 25. The first lug 26 has a first shaft hole 28 and the second lug 27 has a second shaft hole 29. The shaft 5 of the moving wheel 19 passes through the first shaft hole 28 and the second shaft hole 29 in sequence. One end of the shaft 5 is provided with a positioning head 30, which abuts against the first lug 26. The other end of the shaft 5 is the end 22. After the end 22 of the shaft 5 is flattened, its width is greater than the diameter of the first shaft hole 28 and the second shaft hole 29, so that the end 22 of the shaft 5 abuts against the second lug 27, thereby axially positioning the shaft 5 on the bottom plate 25. The moving wheel 19 is rotatably mounted on the shaft 5. During installation, the shaft 5 is first passed through the first shaft hole 28, the moving wheel 19 and the second shaft hole 29 in sequence, and then the end 22 of the shaft 5 is flattened by a flattening fixture.
