The positioning support 15 slides in the lower square hole, and the positioning groove of the positioning support 15 is provided with a positioning mold 12; during work, the installation and disassembly of the pressing plate requires simultaneous operation on both sides of the pressing plate, and the pressing plate needs to be undertaken at the same time, which wastes time in replacing the pressing plate and affects the efficiency of embossing. The corresponding embossed plate 6 is selected according to the size and model of the rubber gasket, and the embossed plate 6 is installed in the support plate 5 through the "U"-shaped groove, and then the embossed plate 6 is fixed in the support plate 5 by the bolts 9 and the block 10, and the embossed plate 6 is installed quickly. After the embossed plate 6 is installed, the rubber gasket is placed on the positioning mold 12 for positioning, and then the positioning mold 12 is pushed to slide on the slide rail 11 The motor 14 is started and the motor 14 drives the screw rod 16 to rotate. The positioning support 15 slides vertically in the slide 13 under the action of the screw rod 16. The positioning support 15 will not shake due to the action of the slide 13 during sliding. When the positioning support 15 rises to place the positioning mold 12 in the positioning groove to complete the positioning of the rubber gasket, the stopper 20 moves upward. During the movement of the stopper 20, it contacts the wedge block 21 and pushes the wedge block 21 to move backward, pushing the slide rod 22 to slide in the signal switch 24 until the signal switch 24 is triggered to transmit a signal to the information controller 17. During this process, the wedge block 21 forms pressure on the return spring 23 to compress the return spring 23. The information controller 17 processes the signal, controls the shutdown of the motor 14, and starts at the same time. The hydraulic cylinder 3 is moved to push the upper pressure plate 4 downward, and the embossing plate 6 is pushed to emboss the rubber gasket on the positioning mold 12. In this process, the embossing plate 6 drives the support plate 5 to move downward, and the limit rod 8 slides downward on the workbench 1 to compress the compression spring 7. After the embossing is completed, the motor 14 reverses, the positioning support 15 moves downward, the wedge block 21 disengages from the stop block 20, the signal switch 24 is turned off, and the information controller 17 controls the hydraulic cylinder 3 to pull up the upper pressure plate 4, and the compression spring 7 recovers to bring the embossing plate 6 back to its original position. The positioning mold 12 on the positioning support 15 is disengaged from the positioning support 15 under the action of the slide rail 11, and the positioning mold 12 is pulled to the outside of the workbench 1 to remove the rubber gasket, and then re-positioned and loaded. The above operations are repeated to complete the production of rubber pads.

[0024] Slide rails 11 are fixedly installed on both sides of the positioning support 15. One end of the slide rail 11 extends to the outside of the workbench 1 and the other end to one side of the positioning support 15, and a limit block is installed. The positioning mold 12 slides on the slide rail 11; when working, the rubber gasket is placed on the positioning mold 12 for fixation, and the positioning mold 12 is pushed to slide on the slide rail 11 to one side to resist the limit block. The positioning mold 12 is located directly below the embossed plate 6 to complete the rapid positioning of the rubber gasket.

[0025] A stopper 20 is fixedly mounted on one side of the positioning support 15. A through hole is opened on the limit block on one side of the stopper 20. A slide rod 22 is slidably mounted in the through hole. A wedge block 21 is fixedly mounted on one end of the slide rod 22. A return spring 23 is provided between the wedge block 21 and the limit block. A signal switch 24 is fixedly mounted outside the through hole on the other side of the limit block. The other end of the slide rod 22 is slidably mounted in the signal switch 24. An information controller 17 is fixedly mounted on the outside of the support arm 2. The information controller 17 is connected to the electrical components. When working, the positioning support 15 rises to position the mold 12 When the rubber gasket is positioned in the positioning groove, the stop block 20 moves upward. During the movement, the stop block 20 contacts the wedge block 21 and pushes the wedge block 21 to move backward, pushing the slide bar 22 to slide in the signal switch 24 until the signal switch 24 is triggered to transmit a signal to the information controller 17. During this process, the wedge block 21 exerts pressure on the return spring 23, compressing the return spring 23. The information controller 17 processes the signal, controls the shutdown of the motor 14, and starts the hydraulic cylinder 3 at the same time, pushing the upper pressure plate 4 to move downward, pushing the embossing plate 6 to emboss the rubber gasket on the positioning mold 12.

[0026] A slide 13 is fixedly installed at the bottom of the workbench 1, and a motor 14 is fixedly installed at the bottom of the slide 13.

The piston rod of the telescopic cylinder 19 pushes the scraper 18 horizontally forward to clean the embossed surface at the bottom of the embossed plate 6 to prevent the rubber gasket from sticking to the surface of the embossed plate 6 and affecting the embossing effect next time.

[0028] Working principle: the installation and disassembly of the pressing plate requires simultaneous operation on both sides of the pressing plate, and the pressing plate needs to be undertaken at the same time, which wastes time in replacing the pressing plate and affects the efficiency of embossing. Select the corresponding embossing plate 6 according to the size of the rubber gasket, install the embossing plate 6 in the support plate 5 through the "U"-shaped groove, and then fix the embossing plate 6 in the support plate 5 through the bolts 9 and the block 10. Quickly install the embossing plate 6. After the embossing plate 6 is installed, place the rubber gasket on the positioning mold 12 for positioning, and then push the positioning mold 12 to slide on the slide rail 11. The positioning support 15 moves to the tail end of the slide rail 11, and the motor 14 is started. The motor 14 drives the screw rod 16 to rotate, and the positioning support 15 slides vertically in the slide cylinder 13 under the action of the screw rod 16. When sliding, the positioning support 15 will not shake due to the action of the slide cylinder 13.

During the movement of the stopper 20, it contacts the wedge block 21 and pushes the wedge block 21 to move backward, pushing the slide rod 22 to slide in the signal switch 24 until the signal switch 24 is triggered to transmit a signal to the information controller 17. During this process, the wedge block 21 forms pressure on the return spring 23, compressing the return spring 23. The information controller 17 processes the signal, controls the motor 14 to be turned off, and starts the hydraulic cylinder 3 at the same time, pushing the upper pressing plate 4 to move downward, pushing the embossing plate 6 to emboss the rubber gasket on the positioning mold 12. In this process, the embossing plate 6 drives the support plate 5 to move downward, and the limit rod 8 slides downward on the workbench 1 to compress the compression spring 7. After the embossing is completed, the motor 14 reverses, the positioning support 15 moves downward, the wedge block 21 disengages from the stop block 20, and the signal switch 24 is turned off. Close, the information controller 17 controls the hydraulic cylinder 3 to pull up the upper pressure plate 4, the compression spring 7 recovers, and the embossed plate 6 is brought back to its original position. The telescopic cylinder 19 is started, and the piston rod of the telescopic cylinder 19 pushes the scraper 18 horizontally forward to clean the embossed surface at the bottom of the embossed plate 6 to prevent the rubber gasket from sticking to the surface of the embossed plate 6 and affecting the embossing effect next time. The positioning mold 12 on the positioning support 15 is separated from the positioning support 15 under the action of the slide rail 11, and the positioning mold 12 is pulled to the outside of the workbench 1 to remove the rubber gasket, and then re-position and fill it. Repeat the above operations to complete the rubber pad production.
