TECHNICAL FIELD

They are widely used in industry, transportation, construction, medical treatment, electronics and other fields. In the production of rubber products, a forming device is needed to hot-press the blank.

[0003] A rubber product forming device is disclosed in patent No. CN221161210U. The patent can directly press and fix the hot press plate by setting a right-angle plate inside the fixed seat, then when the material pressing plate is lifted, the right-angle plate is rotated and opened and inclined to rest on the inside of the upper end of the fixed seat, then when the hot pressing is finished and the hot press plate is lowered, the other end of the right-angle plate is pressed against the material pressing plate to rotate and reset, so that the vertical part is converted to a horizontal state to automatically press the upper surface of the hot press plate. At this time, the hot press plate can be directly taken out through the fixed seat. Further, the spring extension rod drives the support plate to automatically reset to increase the support range of the hot press plate and improve the stability. It is simple to operate and can effectively isolate heat, facilitate taking and placing, and facilitate subsequent discharging and other processing and use.

[0016] Step one: after the moving assembly moves the lower mold base to the middle of the bottom frame, the rubber blank is placed in the lower mold base;

[0017] Step two: when the moving assembly moves the moving seat to the lower side of the hot-pressing mold base, the moving seat can extrude the sliding rod through the pulley, so that the connecting rod drives the first lifting frame to move downward under the guidance of the first limiting frame, and the hot-pressing mold base can automatically extrude the blank on the lower mold base, and the first lifting frame also presses the microswitch to automatically start the heating module in the hot-pressing mold base to heat the blank;

[0018] Step three: after the moving assembly moves the lower mold base to the lower side of the adsorption plate, the pulley contacts the guide plate, and when the moving seat continues to move, the guide plate is extruded to drive the door-shaped frame to move downward, so that the adsorption plate moves to the top of the rubber product under the limitation of the second lifting frame and the second limiting frame, and when the adsorption plate is attached to the workpiece, the piston rod slides in the fixed cylinder to discharge part of the air in the fixed cylinder through the adsorption plate, and in this process, the guide column is inserted into the guide sleeve at the lower end of the fixing frame, the valve core is turned to an open state, and when the adsorption plate is attached to the workpiece, the adsorption plate can be heat-exchanged and cooled by using the tortuous cooling water channel in the adsorption plate, and the heated cooling water is discharged through the water outlet pipe;

[0019] Step four: when the moving seat moves back again, the just compressed buffer spring will reset first, the spring seat will drive the door-shaped frame to move up through the guide plate, at this time the piston rod will slide a small distance in the fixed cylinder first, so that the negative pressure is formed in the fixed cylinder, the rubber product at the bottom can be adsorbed through the air suction flow channel in the adsorption plate, and when the piston rod continues to move up, the fixed cylinder can be pulled to drive the adsorption plate to move up, so the rubber product in the lower mold base can be taken out by using the adsorption force, in this process, when the adsorption plate moves up, the guide column at the upper end of the valve core will also insert into the guide sleeve at the upper part of the fixed frame, at this time, with the rotation of the valve core, the valve housing can be automatically blocked;

[0020] Step five: when the door-shaped frame moves up, the one-way valve will contact with the sealing rod, at the same time, the subsequent sealing rod is always in close contact with the one-way valve by using the compression spring, and after the spring seat resets, the second lifting frame will contact with the magnetic attraction column, and then when the moving seat moves to the middle of the bottom frame, the stop block will be pushed, and the stop block will slide up under the limitation of the sliding block, so that the door-shaped frame is driven to move down a small distance through the rotating plate, and the piston rod will slide in the fixed cylinder first, so that the air pressure in the fixed cylinder increases, therefore, the adsorption plate will not adsorb the operation, and the rubber product will fall onto the conveying belt below under the action of gravity to be stripped.

[0021] The present application provides an energy-saving rubber product forming device and method, which has the following beneficial effects:

[0022] 1、When the double-output shaft reduction motor drives the screw rod to rotate through the gear shifter, the moving seat moves to the lower side of the adsorption plate, the pulley will contact with the guide plate, at this time, with the continuous movement of the moving seat, the bottom frame will shield one side of the lower mold base, so that the buffer spring on one side is compressed, at the same time, the guide plate will be extruded to drive the door-shaped frame to move down, therefore, the adsorption plate will move to the top of the rubber product under the limitation of the second lifting frame and the second limiting frame, and when the adsorption plate is attached to the workpiece, with the continuous movement of the door-shaped frame, the piston rod will slide in the fixed cylinder, so that the air in the fixed cylinder is discharged through the adsorption plate, and then when the moving seat moves back, the just compressed buffer spring will reset first, in this process, the spring seat will drive the door-shaped frame to move up through the guide plate, at this time, the piston rod will slide a small distance in the fixed cylinder first, so that the negative pressure is formed in the fixed cylinder, the rubber product at the bottom can be adsorbed through the air suction flow channel in the adsorption plate, and when the piston rod continues to move up, the fixed cylinder can be pulled to drive the adsorption plate to move up, so the rubber product in the lower mold base can be taken out by using the adsorption force, without manual peeling, so as to improve the safety and convenience in the stripping process.

[0023] 2、The application, when the spring seat is driven by the guide plate to move upwards on the door-shaped frame, the one-way valve will contact the sealing rod, and the subsequent sealing rod is always in close contact with the one-way valve by using the compression spring to block it, so as to avoid gas leakage, and when the spring seat resets, the second lifting frame will contact the magnetic attraction column, and when the moving seat moves to the middle of the bottom frame, it will push the stop block, which will slide upwards under the limit of the sliding block, so as to drive the door-shaped frame to move downwards by a small distance through the rotating plate, at this time, the fixed cylinder position is fixed due to the magnetic attraction column attracting the second lifting frame, so the piston rod will slide in the fixed cylinder first, so that the gas pressure in the fixed cylinder increases, therefore the adsorption plate will not adsorb the operation, and the rubber products will fall onto the conveyor belt below under the action of gravity, so that the rubber products after unloading can be automatically transferred, improving the automation degree of the equipment.

[0024] 3、The application, when the moving seat moves the lower mold seat with the placed rubber blank to the lower side of the hot-pressing mold seat, one side of the lower mold seat will be shielded by the bottom frame, so as to stop moving, at this time, the moving seat can extrude the sliding rod through the pulley, so that the connecting rod drives the first lifting frame to move downwards under the guidance of the first limiting frame, so as to automatically make the hot-pressing mold seat extrude the blank on the lower mold seat, and the first lifting frame also presses the micro switch, so as to automatically start the heating module in the hot-pressing mold seat to heat the blank, and after hot-pressing forming, when the moving seat moves back, the reset spring drives the first lifting frame to move upwards under the limit of the first limiting frame, so that the first lifting frame is separated from the micro switch, therefore, the heating is automatically stopped when no hot-pressing operation is performed, which is helpful to save energy consumption, and the hot-pressing operation can be automatically performed without adding an additional driving source, which is helpful to save the use cost.

[0025] 4、The application, when the adsorption plate is attached to the workpiece, the adsorption plate can be heat-exchanged and cooled by using the tortuous cooling water flow channel in the adsorption plate, so as to quickly cool the hot-pressed rubber products, and the waste heat can be recycled to achieve the energy-saving effect, and when the adsorption plate moves upwards, the guide column at the upper end of the valve core will be inserted into the guide sleeve at the upper end of the fixed frame, at this time, the valve shell can be automatically blocked by the rotation of the valve core to avoid the flow of cooling water, and when the adsorption plate moves downwards and is attached to the workpiece, the guide column will be inserted into the guide sleeve at the lower end of the fixed frame, and the valve core will be turned to an open state, so as to heat-exchange and cool the workpiece in the process of the adsorption plate adsorbing the workpiece and moving upwards, and when the workpiece is separated, the cooling water in the interior stops flowing, therefore, the cooling water can be fully utilized, and the energy-saving effect is further improved.

[0039] In summary, the energy-saving rubber product forming device and method, in use, first start the double-shaft reduction motor 201, drive the moving seat 204 to move through the gear shifter 202 and the screw rod 203, so that the lower mold seat 208 moves to the middle of the bottom frame 1, and then place the rubber blank in the lower mold seat 208. Secondly, when the moving seat 204 moves to the lower side of the hot-pressing mold seat 306, one side of the lower mold seat 208 will be blocked by the bottom frame 1, so as to stop moving. At this time, the moving seat 204 can extrude the sliding rod 301 through the pulley 205, so that the connecting rod 302 drives the first lifting frame 303 to move downward under the guidance of the first limiting frame 304, so as to automatically extrude the blank on the lower mold seat 208 by the hot-pressing mold seat 306. At the same time, the first lifting frame 303 will also press the micro switch 307, so as to automatically start the heating module in the hot-pressing mold seat 306 to heat the blank. After hot-pressing forming, when the moving seat 204 moves back, the return spring 305 will drive the first lifting frame 303 to move upward under the limitation of the first limiting frame 304, so that the first lifting frame 303 is separated from the micro switch 307. Then, after the moving seat 204 moves to the lower side of the adsorption plate 407, the pulley 205 will contact the guide plate 402. At this time, with the continuous movement of the moving seat 204, the buffer spring 207 on one side will be compressed due to the blocking of the bottom frame 1 on one side of the lower mold seat 208, and the guide plate 402 will be extruded to drive the door-shaped frame 403 to move downward. Therefore, the adsorption plate 407 will move to the top of the rubber product under the limitation of the second lifting frame 408 and the second limiting frame 409. When the adsorption plate 407 is attached to the workpiece, with the continuous downward movement of the door-shaped frame 403, the piston rod 404 will slide in the fixed cylinder 406, so as to exhaust part of the air in the fixed cylinder 406 through the adsorption plate 407. In this process, the guide column 604 will be inserted into the guide sleeve 606 at the lower end of the fixed frame 605, and the valve core 603 will be turned to an open state. When the adsorption plate 407 is attached to the workpiece, the adsorption plate 407 can be heat-exchanged and cooled by using the tortuous cooling water flow channel inside the adsorption plate 407. The heated cooling water will be discharged through the water outlet pipe 607 for recycling. Then, when the moving seat 204 moves back again, the just-compressed buffer spring 207 will reset. In this process, the spring seat 401 will drive the door-shaped frame 403 to move upward through the guide plate 402. At this time, the piston rod 404 will first slide a small distance in the fixed cylinder 406, so that a negative pressure is formed in the fixed cylinder 406, which can adsorb the rubber product at the bottom through the air suction flow channel in the adsorption plate 407. When the piston rod 404 continues to move upward, it can pull the fixed cylinder 406 to drive the adsorption plate 407 to move upward, so as to take out the rubber product in the lower mold seat 208 by using the adsorption force. In this process, when the adsorption plate 407 moves upward, the guide column 604 at the upper end of the valve core 603 will be inserted into the guide sleeve 606 at the upper part of the fixed frame 605.At this time, the rotation of the valve core 603 can automatically block the inside of the valve shell 601, avoiding the cooling water flow, finally, the spring seat 401 drives the door frame 403 to move up in the process, the one-way valve 405 will contact with the sealing rod 502, at the same time, the compression spring 503 makes the subsequent sealing rod 502 always close to the one-way valve 405, and the one-way valve 405 is blocked, and when the spring seat 401 resets, the second lifting frame 408 will contact with the magnetic column 501, and when the moving seat 204 moves to the middle of the bottom frame 1, the stop block 505 will be pushed, the stop block 505 will slide upward under the limiting of the sliding block 506, so as to drive the door frame 403 to move downward a small distance through the rotating plate 504, at this time, the magnetic column 501 will attract the second lifting frame 408 to fix the position of the fixed cylinder 406, the piston rod 404 will slide in the inside of the fixed cylinder 406 first, so that the air pressure in the fixed cylinder 406 increases, so the adsorption plate 407 will not adsorb the operation, and the rubber products will fall to the conveying belt below under the action of gravity, and the rubber products after unloading are automatically transferred.
