One end of the L-shaped connecting rod 76 passes through the rotating slide groove 73 and is slidably connected inside the limit groove 74. The other end of the L-shaped connecting rod 76 is rotatably connected to the pressure plate 75.

The inside of the vertical slide 91 is slidably connected to the blocking rod 94, and the blocking rod 94 is connected to the tension spring 92 to drive the blocking rod 94 to slide and reset.

[0023] The use method and advantages of the present invention: The compression device for producing polymer chemical materials has the following working process: like Figures 1 to 13 As shown: When in use, first place the metal material and other materials (mixed materials such as polyethylene) into the interior of the compression barrel 4, start the drive motor 3, and the drive motor 3 drives the hollow rod 63 to rotate. When the hollow rod 63 rotates, it will drive the sliding connected gear disc 2 67 to rotate. At this time, the gear disc 2 67 is in a meshing state with the gear disc 1 66. When the gear disc 2 67 rotates, it drives the connecting rod 62 meshed with the gear disc 1 66 to rotate. When the connecting rod 62 rotates, it drives the sliding pressing plate 52 to rotate. When the sliding pressing plate 52 rotates, it will drive the internal limited sliding sliding connecting rod 61 to rotate. When the sliding connecting rod 61 rotates, it drives the pressure plate 75 connected to the lower end by the L-shaped connecting rod 76 to rotate. In this way, when the pressure plate 75 rotates, the material can be pre-treated to achieve mixing treatment, thereby preventing the uniformity of the raw materials from being uneven during the die-casting process.

[0024] The cylinder 2 is started, and the cylinder 2 drives the driving motor 3 and the following mechanisms to slide downward. When the hollow rod 63 moves downward, the connecting rod 62 slides downward at the same time. The hollow rod 63 also drives the internal gear plate 2 67 and the retaining ring 68 fixedly connected to the surface of the gear plate 2 67 to slide downward. When the retaining ring 68 drops to the surface of the blocking rod 94, the blocking rod 94 is in a relatively static state, and the tension spring 92 is squeezed while the retaining ring 68 is squeezed in the opposite direction. When the retaining ring 68 is squeezed, the gear plate 2 67 is driven to slide upward on the surface of the hollow rod 63. At this time, the pressing plate 51 has entered the interior of the compression barrel 4. When the gear plate 2 67 moves upward, it will separate from the gear plate 1 66, and the sliding pressing plate 52 will stop rotating through the connecting rod 62. At the same time, when the gear plate 2 67 moves upward, it drives the T-shaped slide bar 64 inside the hollow rod 63 to slide upward, and when the T-shaped slide bar 64 slides upward, it drives the lower end fixed The fixedly connected chute block 610 slides upward at the same time. When the chute block 610 slides upward, it will slide outward inside the hollow rod 63 through its own inclined surface squeezing the limit slide bar 611, and while sliding, it will enter the circulation chute 65 opened in the connecting rod 62. When the sliding pressing plate 52 is in a stationary state, the connecting rod 62 will also be in a stationary state. At this time, the rotation of the hollow rod 63 will form an up and down reciprocating motion in the circulation chute 65 through the extended limit slide bar 611. The hollow rod 63 reciprocates during the rotation process, and at the same time drives the sliding connecting rod 61 to rotate and reciprocate up and down. During the operation of the sliding connecting rod 61, it also drives the lower end pressure plate 75 to rotate and reciprocate up and down. The rotation speed at this time is lower than that of the mixing stage, and the raw materials are pressed and the mixed materials are repeatedly squeezed to discharge the internal air. It will be fuller during die casting, thereby improving the precision of the product.

[0025] Then the driving motor 3 stops rotating, and the cylinder 2 starts to push the pressing plate 51 at the lower end downward. First, the sliding connecting rod 61 contacts the bottom surface of the compression barrel 4, making it in a relatively static state. Then the sliding pressing plate 52 slides downward on the surface of the sliding connecting rod 61, and at the same time, the sliding support rod 71 will be stuck by the upper end of the sliding pressing plate 52, so that the sliding support rod 71 is also in a relatively static state. At this time, the sliding support rod 71 will squeeze the limiting notch 74. When the limiting notch 74 is squeezed, it will drive the L-shaped connecting rod 76 to slide downward inside the rotating slide groove 73. When the L-shaped connecting rod 76 slides, it also pulls the pressure plate 75 to slide downward inside the rotating slide groove 73, and when it contacts the compression barrel 4 bottom rotates at the same time, and there will also be a certain amount of rising space during rotation, driving the pressing plate 75 to complete a 180° rotation. The plane of the pressing plate 75 will face downward and be flush with the bottom end of the sliding connecting rod 61. At this time, the cylinder will drive the sliding pressing plate 52 to continue to slide downward through the hollow rod 63 together with the sliding connecting rod 61. When the sliding pressing plate 52 contacts the bottom surface, it will also slide upward inside the pressing plate 51. At this time, the pressing plate 75 will be embedded in the fitting groove 54, and the sliding pressing plate 52 will slide into the inside of the pressing plate 51, so that the pressing plate 51 forms a complete circle, pressing the raw materials for die-casting. At this time, the raw materials are mixed and exhausted, which not only improves the qualified rate, but also improves the work efficiency.

[0026] When the pressure plate 52 is in the downward direction, the pressure plate 52 is pressed against the support block 86, and the support block 86 is pressed against the support block 86, so that the support block 86 slides upward. When the support block 86 is in the upward direction, the air filter 84 is driven upward, and the air filter 84 slides upward in the threaded groove 83 provided on the telescopic rod 82, driving the telescopic rod 82 to rotate. When the telescopic rod 82 rotates, the sealing gasket 85 is driven to rotate, and finally the sealing gasket 85 is driven upward a little, sealing the bottom of the pressure reducing groove 81 and fitting with the bottom of the pressing plate 51, forming a complete pressing. When the retaining ring 68 slides up and down, it will be relatively squeezed by the blocking rod 94, and when the blocking rod 94 slides to the top in the vertical slide groove 91, it will be separated from the retaining ring 68 through the inclined block 93, so that the blocking rod 94 will exchange the opposite side with the retaining ring 68, which is convenient for the next operation. Finally, the entire mechanism is reset by resetting the cylinder.
