It is worth noting that a heating mechanism is arranged on the first lower die 8, the second lower die 9 and the upper die 5 for heating the material, and the heating mechanism can be an electric heating wire or heating oil, which is integrated in the mold. This is a prior art, and the specific structure of the mold is not repeated here.

[0026] In this embodiment, the pressure mechanism includes a guide block 3 and a driving member. The guide block 3 is fixed on the top of the upper die 5. First sliders 2 are provided on both sides of the outer wall of the guide block 3. Slide grooves are provided on both sides of the inner wall of the base 1. The guide block 3 is connected to the base 1 for sliding up and down movement through the first slider 2 and the slide groove. A swing arm 4 is hinged on the top of the guide block 3. The driving member is provided on the base 1 for driving the swing arm 4 to move up and down.

[0027] The driving member drives the swing arm 4 to move, and further drives the upper die 5 to move up and down with the cooperation of the guide block 3, the slide groove and the first slider 2, so that the upper die 5 hot presses the material on the first lower die 8 or the second lower die 9 respectively.

[0028] In this embodiment, the driving member includes a rotating motor 17, a rotating shaft 14, a lower driving wheel 18, an upper driving wheel 16 and a linkage belt 15. The rotating motor 17 is fixedly mounted on the rear side of the machine base 1, the lower driving wheel 18 is fixed to the outside of the output shaft of the rotating motor 17, the upper driving wheel 16 is located in front of the lower driving wheel 18, and the lower driving wheel 18 and the upper driving wheel 16 are connected by a linkage belt 15. The rotating shaft 14 is rotatably mounted on the upper part of the machine base 1, the upper driving wheel 16 is fixed to the outside of one end of the rotating shaft 14, a crankshaft is fixed in the middle of the rotating shaft 14, and the swing arm 4 is rotatably sleeved on the crankshaft;

[0029] The rotating motor 17 adopts a forward and reverse motor with model number Y315L2-2. When the rotating motor 17 is working, it drives the rotating shaft 14, the lower driving wheel 18, the upper driving wheel 16 and the linkage belt 15 to rotate forward and reverse. Under the limitation of the guide block 3, the slide groove and the first slider 2, the upper die 5 moves up and down.

[0030] In this embodiment, the two sets of stoppers 13 are fixed to the side surfaces of both ends of the two sets of slide rails 7. When the first lower die 8 slides to the rightmost end and the second lower die 9 slides to the leftmost end, the other two sets of stoppers 13 contact the left side of the second lower die 9, and two sets of stoppers 13 contact the right side of the first lower die 8.

[0031] Two groups of stoppers 13 limit the first lower die 8. When they contact the right side of the first lower die 8, the second lower die 9 is just below the upper die 5. Similarly, when the other two groups of stoppers 13 contact the left side of the second lower die 9, the first lower die 8 is just below the upper die 5. A strip slide groove is provided on the slide rail 7. The first lower die 8 and the second lower die 9 have the same structure and material. Two groups of second sliders 19 are fixed to the bottom of the first lower die 8 and the second lower die 9. The outer wall of the lower end of the second slider 19 is slidably connected to the inner wall of the strip slide groove.

[0032] In this embodiment, the first lower pressing die 8 and the second lower pressing die 9 are respectively welded with a first hand pull rod 11 and a second hand pull rod 12 on the side away from each other. The first hand pull rod 11 and the second hand pull rod 12 are both U-shaped rods, and the size and material of the two are the same;

[0033] The first hand pull rod 11 and the second hand pull rod 12 are made of anti-scalding material. When the hot pressing is completed, the staff can pull the first hand pull rod 11 and the second hand pull rod 12 to realize the movement of the first lower die 8 and the second lower die 9 to avoid direct contact with the first lower die 8 and the second lower die 9 by hand, which would burn the hands due to the high temperature on the first lower die 8 and the second lower die 9.

[0034] The working principle and use process of the utility model are as follows: when in use, the first lower die 8 is placed inside with cut rubber strips or other processed and formed raw materials, the first lower die 8 is aligned with the upper die, and then the rotary motor 17 is started to work, the rotary motor 17 drives the lower drive wheel 18, the linkage belt 15 and the upper drive wheel 16 to rotate, the upper drive wheel 16 drives the rotating shaft 14 and the crank 4 to rotate, and with the cooperation of the slider 2 and the slide groove, the crank 4 drives the guide block 3 and the upper die 5 to move downward, so that the upper die 5 performs hot pressing on the material on the first lower die 8. At this time, the rubber strip is manually placed inside the second lower die 9 without waiting for the hot pressing of the material on the first lower die 8 to be completed, which can save the time for placing the material and improve the work efficiency. After the pressing is completed, the crank 4 drives the guide block 3 and the upper die 5 to move upward, and the upper die 5 moves away from the first lower die 8. The second hand pull rod 12 is manually pulled to the right, and the second hand pull rod 12 drives the first lower die 8 to move to the right. When the right side of the first lower die 8 moves to contact the side of two groups of blocks 13, the two groups of blocks 13 can block the first lower die 8. At this time, the second lower die 9 is directly below the upper die 5, and the material on the second lower die 9 continues to be hot-pressed, and the material continues to be placed on the first lower die 8. After the hot pressing of the material on the second lower die 9 is completed, the first hand pull rod 11 is pulled to the left, and the first hand pull rod 11 drives the second lower die 9 to move to the left, which is convenient for manual material collection and discharge, thereby improving the working efficiency of the press.

[0035] 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.
