[0027] Machine base 1: Provides a stable foundation for the entire laminating machine. Ensures the stability of the machine during the laminating process, reduces vibration and shaking, and ensures laminating accuracy.

[0028] Foot pads 2: Threaded to the bottom of the base 1, usually four in number. They can be adjusted to keep the press level even on uneven ground, further enhancing stability.

[0029] Lower die base 3: fixed on the machine base 1, used to install the lower die plate 11 and the lower concave die 12. Provide fixation and support for the lower die to ensure the accuracy of the lower die position.

[0030] Positioning column 4: fixed on the lower die base 3, and the top is connected to the top cover 5. It plays a role in guiding and positioning the movement of the upper die base 7, ensuring that the upper die base 7 moves vertically up and down, and ensuring the accuracy of the pressing.

[0031] Top cover 5: fixed on the top of the positioning column 4, used to install the fixed end of the hydraulic cylinder 6. Provide a stable installation position for the hydraulic cylinder 6 and support the work of the hydraulic cylinder 6.

[0032] Hydraulic cylinder 6: Its fixed end is connected to the top cover 5, and its movable end is connected to the upper die base 7. It provides the power required for pressing and pushes the upper die base 7 to move up and down.

[0033] Upper die base 7: holes are provided at the four corners for sliding connection with positioning columns 4, and T-slots are provided for clamping upper die plate 9. Driven by hydraulic cylinder 6, it moves up and down to realize the pressing action, and the T-slots facilitate the installation and replacement of upper die plate 9.

[0034] T-slot: It is respectively arranged on the upper die base 7 and the lower die base 3. It is convenient for the sliding installation and fixation of the upper die plate 9 and the lower die plate 11, and convenient for the replacement and adjustment of the die.

[0035] The upper mold plate 9 and the lower mold plate 11 are L-shaped on the side and are fixed with the upper mold base 7 and the lower mold base 3 by bolts. As the installation basis of the upper punch 10 and the lower die 12, the L-shaped design and bolt fixation ensure that the mold plate is firmly installed, and different mold plates can be replaced according to different pressing requirements.

[0036] Upper convex mold 10 and lower concave mold 12: The upper convex mold 10 is connected to one end of the upper mold plate 9, and its shape matches that of the lower concave mold 12. They cooperate with each other to press the rubber surface of the shoe so that the rubber surface fits tightly.

[0037] Groove 13 and lever 14: Groove 13 is provided on lower die 12, and lever 14 is placed in groove 13. Groove 13 provides a placement space for lever 14, and lever 14 is used to lift the pressed sole, which is convenient for unloading.

[0038] Here’s how it works:

[0039] First, the shoe parts to be pressed are placed on the lower concave mold 12 and the positions must be accurately aligned.

[0040] Then, the hydraulic cylinder 6 is started. The movable end of the hydraulic cylinder 6 pushes the upper die seat 7 to move downward along the positioning column 4. The upper punch 10 on the upper die seat 7 moves downward accordingly and gradually approaches the lower concave die 12.

[0041] In this process, the upper convex mold 10 and the lower concave mold 12 cooperate with each other to apply pressure to the rubber surface of the shoe placed in the middle to achieve pressing.

[0042] The holes at the four corners of the upper die seat 7 are slidably connected to the positioning columns 4 to ensure that the upper die seat 7 moves vertically and smoothly, thereby ensuring the accuracy of the pressing.

[0043] The upper mold plate 9 and the lower mold plate 11 are slidably connected to the upper mold base 7 and the lower mold base 3 respectively through T-slots, so that different mold plates can be replaced according to different shoe models and pressing requirements.

[0044] When the pressing is completed, the movable end of the hydraulic cylinder 6 retracts, driving the upper die seat 7 to move upward, and the upper punch 10 is separated from the lower die 12.

[0045] The lever 14 is located in the groove 13 of the lower concave die 12 and is used to lift the pressed sole to facilitate the operator to perform the unloading operation.

[0046] like Figure 1 As shown, in some embodiments, there are four foot pads 2, and the four foot pads 2 are used for adjustable support; by adjusting the four foot pads 2, it is possible to adapt to different flatness of the ground. For example, if the ground is tilted or uneven, adjusting the heights of the four foot pads 2 respectively can keep the machine base 1 in a horizontal state, thereby ensuring that the pressing machine will not shake or tilt due to the uneven ground during operation, thereby ensuring the accuracy and quality of pressing.

[0047] like Figure 1 As shown, in some embodiments, the four corners of the upper die base 7 are provided with holes, and the upper die base 7 is slidably connected with the positioning column 4; when the pressing machine is working, when the hydraulic cylinder 6 pushes the upper die base 7 to move up and down, the positioning column 4 passes through these holes, providing precise guidance for the movement of the upper die base 7.

[0048] like Figure 1 As shown, in some embodiments, the upper punch 10 is adapted to the shape of the lower die 12; this adaptability enables the upper punch 10 to be accurately embedded in the lower die 12, thereby achieving precise pressing of the rubber surface of the shoe.

[0049] like Figure 3 As shown, in some embodiments, the lever 14 is located inside the lower die 12 and does not contact the shoe; such a position arrangement can fully utilize the space inside the lower die 12 without increasing the overall volume of the press, making the structure more compact.

[0050] like Figure 1 As shown, in some embodiments, the side shapes of the upper mold plate 9 and the lower mold plate 11 are L-shaped, and the side surfaces are threadedly fastened with the upper mold base 7 and the lower mold base 3 by bolts; the L-shaped side surface design increases the contact area between the mold plate and the mold base, and improves the stability of the connection. During the pressing process, it can withstand greater pressure and impact force, reducing the possibility of loosening or displacement of the mold plate.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
