Description

Technical Field

[0001] The invention relates to the technical field of rubber product molding, in particular to an energy-saving rubber product molding device and method. Background Art

[0002] Rubber products are made of natural rubber or synthetic rubber as the main raw material, and are made through a series of processing processes. They have high elasticity, wear resistance, corrosion resistance, insulation and other properties. They are widely used in many fields such as industry, transportation, construction, medical treatment, electronics, etc. When producing rubber products, a molding device is needed to hot-press the blank into shape.

[0003] For example, the patent with publication number CN221161210U discloses a rubber product forming device. This patent can directly press and fix the hot pressing plate after a right-angle plate is arranged inside the fixed seat, and then when the material pressing plate is lifted, the right-angle plate is driven to rotate and open and tilted to be placed on the inner position of the upper end of the fixed seat. Then, when the hot pressing plate is lowered after the hot pressing is completed, the material pressing plate is used to support the other end of the right-angle plate to drive it to rotate and reset, so that the upright part is converted to a horizontal state and automatically presses the upper surface of the hot pressing plate. At this time, the hot pressing plate can be directly taken out through the fixed seat, and the spring telescopic rod is further used to drive the support plate to automatically reset to increase the support range of the hot pressing plate and improve the stability. The operation is simple and can effectively isolate the heat for easy access and placement, and is convenient for subsequent unloading and other processing. However, in actual use, it is still necessary to manually shovel the product down for unloading, so there is still a probability of scalding accidents during operation, resulting in a relatively general problem of overall safety of use.

[0010] Furthermore, the hot pressing assembly also includes a reset spring, a hot pressing die seat and a touch switch. The reset spring is sleeved on the outer side of the upper end of the first lifting frame, and the hot pressing die seat is fixed to the bottom of the first lifting frame.

[0011] Furthermore, anti-sticking components are provided on the upper part and both sides of the bottom frame of the unloading component, and the anti-sticking components include magnetic columns, sealing rods and compression springs.

The inner center of the second limiting frame is slidably connected with a sealing rod, and the lower end of the sealing rod is sleeved with a compression spring on the outer side.

[0012] Furthermore, the anti-sticking component also includes a rotating plate, a stopper and a slider.

One end of the rotating plate is slidably connected to a stopper, and a slider is fixed to one side of the stopper, and the slider is slidably connected to the bottom frame.

[0013] Furthermore, a heat exchange component is provided on one side of the adsorption plate, and the heat exchange component includes a valve housing, a water inlet pipe, a valve core and a guide column.

[0014] Furthermore, the heat exchange assembly also includes a fixing frame, a guide sleeve and a water outlet pipe. The fixing frame is placed on the top of the other end of the bottom frame, and the upper and lower ends of the fixing frame are provided with guide sleeves. One side of the adsorption plate is connected to the adsorption plate.

[0015] Furthermore, the energy-saving rubber product molding method is applied to the energy-saving rubber product molding device, comprising the following steps:

[0016] Step 1: After starting the material transfer assembly to move the lower die seat to the middle of the bottom frame, place the rubber blank in the lower die seat;

[0017] Step 2: When the movable seat is moved to the bottom of the hot pressing die seat by the material moving assembly, the movable seat can squeeze 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 limit frame, so that the hot pressing die seat can automatically extrude the blank on the lower die seat, and at the same time, the first lifting frame will also press the touch switch to automatically start the heating module inside the hot pressing die seat to heat the blank;

[0018] Step 3: After controlling the material shifting assembly to move the lower die seat to the bottom of the adsorption plate, the pulley will contact the guide plate. At this time, as the moving seat continues to move, the guide plate will be squeezed and can drive the portal frame to move downward. Therefore, the adsorption plate will move to the top of the rubber product under the limit of the second lifting frame and the second limit frame. After the adsorption plate fits the workpiece, as the portal frame continues to move downward, the piston rod will slide in the fixed cylinder, thereby discharging part of the air inside the fixed cylinder through the adsorption plate. During this process, the guide column will be inserted into the guide sleeve at the lower end of the fixed frame, and the valve core will rotate to the open state. After the adsorption plate fits the workpiece, the tortuous cooling water flow channel inside the adsorption plate can be used to exchange heat and cool the adsorption plate, and the heated cooling water will be discharged through the outlet pipe.

[0019] Step 4: When the moving seat moves back again, the buffer spring that has just been compressed will reset first, and the spring seat will drive the door frame to move up through the guide plate. At this time, the piston rod will first slide a short distance in the fixed cylinder, so that negative pressure is formed inside the fixed cylinder, and the rubber product at the bottom can be adsorbed through the suction flow channel inside the adsorption plate. When the piston rod continues to move upward, it can pull the fixed cylinder to drive the adsorption plate to move up, so the rubber product in the lower mold seat can be taken out by the adsorption force. In this process, when the adsorption plate moves up, it will also drive the guide column at the upper end of the valve core to be inserted into the guide sleeve on the upper part of the fixed frame. At this time, as the valve core rotates, the inside of the valve shell can be automatically blocked;

[0020] Step 5: When the portal frame moves upward, the one-way valve will contact the sealing rod. At the same time, the compression spring will be used to ensure that the subsequent sealing rod is always in close contact with the one-way valve. When the spring seat is reset, the second lifting frame will contact the magnetic column. Later, when the moving seat moves to the middle of the bottom frame, it will push the block, and the block will slide upward under the limit of the slider, thereby driving the portal frame to move down a short distance through the rotating plate. The piston rod will first slide inside the fixed cylinder, thereby increasing the air pressure inside the fixed cylinder. Therefore, the adsorption plate will not be adsorbed, and the rubber product will fall to the conveyor belt below under the action of gravity for removal.

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

[0022] 1. In the present invention, when the double-output shaft reduction motor drives the screw to rotate through the gear commutator, so that the movable seat moves to the bottom of the adsorption plate, the pulley will contact the guide plate. At this time, as the movable seat continues to move, the bottom frame will block one side of the lower die seat, thereby compressing the buffer spring on one side, and at the same time, the guide plate will be squeezed to drive the door frame to move downward, so the adsorption plate will move to the top of the rubber product under the limit of the second lifting frame and the second limit frame, and when the adsorption plate is fitted with the workpiece, as the door frame continues to move downward, the piston rod will slide in the fixed cylinder, thereby the fixed cylinder The internal air is discharged through the adsorption plate. Later, when the moving seat moves back, the buffer spring that has just been compressed will reset first. During this process, the spring seat will drive the portal frame to move upward through the guide plate. At this time, the piston rod will first slide a short distance in the fixed cylinder, so that negative pressure is formed inside the fixed cylinder, and the rubber product at the bottom can be adsorbed through the suction air channel inside the adsorption plate. When the piston rod continues to move upward, it can pull the fixed cylinder to drive the adsorption plate to move up. Therefore, the rubber product in the lower mold seat can be taken out by the adsorption force without manual peeling, thereby improving the safety and convenience of the unloading process.

[0023] 2. According to the present invention, when the spring seat drives the portal frame to move upward through the guide plate, the one-way valve will contact the sealing rod, and the compression spring will make the subsequent sealing rod always close to the one-way valve to seal it and prevent gas leakage. After the spring seat is reset, the second lifting frame will contact the magnetic column. Subsequently, when the moving seat moves to the middle of the bottom frame, it will push the block, and the block will slide upward under the limit of the slider, thereby driving the portal frame to move down a short distance through the rotating plate. At this time, the magnetic column will absorb the second lifting frame to fix the position of the fixed cylinder, and the piston rod will first slide inside the fixed cylinder, thereby increasing the air pressure inside the fixed cylinder. Therefore, the adsorption plate will not perform the adsorption operation, and the rubber product will fall onto the conveyor belt below under the action of gravity, so that the rubber products after unloading can be automatically transported, thereby improving the automation level of the equipment.

[0024] 3. According to the present invention, when the movable seat moves the lower die seat with the rubber blank placed on it to the bottom of the hot pressing die seat, one side of the lower die seat will be blocked by the bottom frame, thereby stopping movement. At this time, the movable seat can squeeze 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 limit frame, so that the hot pressing die seat can automatically extrude the blank on the lower die seat. At the same time, the first lifting frame will also press the touch switch, so that the heating module inside the hot pressing die seat can be automatically started to heat the blank. After hot pressing molding, when the movable seat moves back, the reset spring will drive the first lifting frame to move up under the limit of the first limit frame, so that the first lifting frame is separated from the touch switch. Therefore, heating is automatically stopped when hot pressing operation is not performed, which is beneficial to saving energy consumption. At the same time, hot pressing operation can be automatically performed without adding an additional driving source, which is beneficial to saving use cost.

[0025] 4. After the adsorption plate is fitted with the workpiece, the present invention can utilize the tortuous cooling water flow channel inside the adsorption plate to exchange heat and cool the adsorption plate, quickly cool the rubber product after hot pressing, and recover the waste heat to achieve energy-saving effect. When the adsorption plate moves up, it will also drive the guide column at the upper end of the valve core to be inserted into the guide sleeve on the upper part of the fixed frame. At this time, as the valve core rotates, the inside of the valve shell can be automatically blocked to prevent the circulation of cooling water. When the adsorption plate moves down and fits 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 rotate to an open state, thereby performing heat exchange and cooling on the workpiece during the process of the adsorption plate adsorbing the workpiece and moving up. When separated from the workpiece, the internal cooling water will automatically stop flowing. Therefore, the cooling water can be fully utilized to further improve the energy-saving effect.

[0036] The specific operation is as follows: start the double-output shaft reduction motor 201, and drive the movable seat 204 to move through the gear commutator 202 and the screw 203, so that the lower mold seat 208 can be moved to the middle of the bottom frame 1. There is no obstruction above the lower mold seat 208, which is convenient for placing the rubber blank in the lower mold seat 208. After that, when the movable seat 204 is controlled to move to the bottom of the hot pressing mold seat 306, one side of the lower mold seat 208 will be blocked by the bottom frame 1, thereby stopping the movement. At this time, the movable seat 204 can squeeze the slide 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 limit frame 304, and it can automatically The hot pressing die seat 306 is used to extrude the blank on the lower die seat 208, and the first lifting frame 303 also presses the touch switch 307 at the same time, which can automatically start the heating module inside the hot pressing die seat 306 to heat the blank.

When the movable seat 204 moves to the bottom of the adsorption plate 407, the pulley 205 will contact the guide plate 402. At this time, as the movable seat 204 continues to move, the bottom frame 1 will block one side of the lower mold seat 208, thereby compressing the buffer spring 207 on one side, and at the same time, the guide plate 402 will be squeezed to drive the door 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, and when the adsorption plate 407 is in contact with the workpiece, as the door frame 403 continues to move downward, the piston rod 404 will slide in the fixed cylinder 406, thereby fixing the workpiece. Part of the air inside the fixed cylinder 406 is discharged through the adsorption plate 407, and when the movable seat 204 moves back, the buffer spring 207 that has just been compressed will reset first. During this process, the spring seat 401 will drive the door frame 403 to move upward through the guide plate 402. At this time, the piston rod 404 will first slide a short distance in the fixed cylinder 406, so that negative pressure is formed inside the fixed cylinder 406, and the rubber product at the bottom can be adsorbed through the suction flow channel inside the adsorption plate 407, and 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 that the rubber product in the lower mold seat 208 can be taken out by utilizing the adsorption force.

[0037] See also Figures 5 to 7, anti-sticking components 5 are provided on the upper part of the unloading component 4 and on both sides of the bottom frame 1, and the anti-sticking components 5 include magnetic columns 501, sealing rods 502 and compression springs 503. The top two ends of the second lifting frame 408 are magnetically connected with magnetic columns 501, and the magnetic columns 501 are fixedly connected to the second limiting frame 409. The sealing rod 502 is slidably connected to the inner center of the second limiting frame 409, and the compression spring 503 is sleeved on the outer side of the lower end of the sealing rod 502. The anti-sticking component 5 also includes a rotating plate 504, a stopper 505 and a slider 506. The rotating plates 504 are rotatably connected to the two sides of the bottom frame 1, and the rotating plates 504 are slidably connected to the door frame 403. One end of the rotating plate 504 is slidably connected to the stopper 505, and one side of the stopper 505 is fixed. A slider 506 is fixed, and the slider 506 is slidably connected to the bottom frame 1. A heat exchange component 6 is arranged on one side of the adsorption plate 407, and the heat exchange component 6 includes a valve shell 601, a water inlet pipe 602, a valve core 603 and a guide column 604. A valve shell 601 is arranged on one side of the adsorption plate 407, and one end of the valve shell 601 is connected to the water inlet pipe 602, the valve core 603 is rotatably connected inside the valve shell 601, and the upper and lower ends of the valve core 603 are connected to the guide column 604, the heat exchange component 6 also includes a fixing frame 605, a guide sleeve 606 and a water outlet pipe 607, a fixing frame 605 is arranged on the top of the other end of the bottom frame 1, and the upper and lower ends of the fixing frame 605 are provided with guide sleeves 606, and one side of the adsorption plate 407 is connected to the adsorption plate 407;

[0038] The specific operation is as follows. When the adsorption plate 407 moves down and fits the workpiece, 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 rotate to the open state. Therefore, when the adsorption plate 407 fits the workpiece, the tortuous cooling water flow channel inside the adsorption plate 407 can be used to exchange heat and cool the adsorption plate 407, and the rubber product after hot pressing can be quickly cooled. The heated cooling water will be discharged through the outlet pipe 607, and the waste heat can be recovered. When the adsorption plate 407 moves up, it will also drive the guide column 604 at the upper end of the valve core 603 to be inserted into the guide sleeve 606 at the upper part of the fixed frame 605. At this time, as the valve core 603 rotates, the inside of the valve housing 601 can be automatically blocked to prevent the circulation of cooling water, so that the workpiece can be cooled by heat exchange during the process of the adsorption plate 407 adsorbing the workpiece and moving up. When separated from the workpiece, the internal cooling water will automatically stop flowing. In this process, the guide plate 402 When the door frame 403 is driven to move upward, the one-way valve 405 will contact the sealing rod 502. At the same time, the compression spring 503 is used to make the subsequent sealing rod 502 always close to the one-way valve 405 to block it and prevent gas leakage. After the spring seat 401 is reset, the second lifting frame 408 will contact the magnetic column 501. Subsequently, when the movable seat 204 moves to the middle of the bottom frame 1, it will push the stopper 505, and the stopper 505 will slide upward under the limit of the slider 506, thereby driving the door frame 403 to move down a short distance through the rotating plate 504. At this time, because the magnetic column 501 will absorb the second lifting frame 408 to fix the position of the fixed cylinder 406, the piston rod 404 will first slide inside the fixed cylinder 406, thereby increasing the air pressure inside the fixed cylinder 406, so that the adsorption plate 407 will not be adsorbed, and the rubber product will fall onto the conveyor belt below under the action of gravity, and the rubber product after unloading will be automatically transported.

[0039] In summary, when the energy-saving rubber product molding device and method are used, first start the double-output shaft reduction motor 201, and drive the movable seat 204 to move through the gear commutator 202 and the screw 203, so that the lower mold seat 208 can be moved to the middle of the bottom frame 1, and then the rubber blank is placed in the lower mold seat 208. Secondly, when the movable seat 204 moves to the bottom of the hot pressing mold seat 306, one side of the lower mold seat 208 will be blocked by the bottom frame 1, thereby stopping the movement. At this time, the movable seat 204 can squeeze 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 that the hot pressing mold seat 306 can automatically extrude the blank on the lower mold seat 208. The lowering frame 303 will also press the touch switch 307, which can automatically start the heating module inside the hot pressing mold seat 306 to heat the blank. After hot pressing, when the moving seat 204 moves back, the reset spring 305 will drive the first lifting frame 303 to move up under the limit of the first limit frame 304, so that the first lifting frame 303 is separated from the touch switch 307. Then, after the moving seat 204 moves to the bottom of the adsorption plate 407, the pulley 205 will contact the guide plate 402. At this time, as the moving seat 204 continues to move, the bottom frame 1 will block one side of the lower mold seat 208, thereby compressing the buffer spring 207 on one side, and at the same time, the guide plate 402 will be squeezed to drive the door frame 403 to move down, so that the adsorption The plate 407 will move to the top of the rubber product under the limit of the second lifting frame 408 and the second limiting frame 409, and when the adsorption plate 407 is in contact with the workpiece, as the door frame 403 continues to move downward, the piston rod 404 will slide in the fixed cylinder 406, so that part of the air inside the fixed cylinder 406 will be discharged 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 rotate to the open state. When the adsorption plate 407 is in contact with the workpiece, the tortuous cooling water flow channel inside the adsorption plate 407 can be used to exchange heat and cool the adsorption plate 407. The heated cooling water will be discharged through the outlet pipe 607 so that it can be recycled. Then, when the moving When the movable seat 204 moves back again, the buffer spring 207 that has just been compressed will reset first. During this process, the spring seat 401 will drive the door frame 403 to move upward through the guide plate 402. At this time, the piston rod 404 will first slide a short distance in the fixed cylinder 406, so that negative pressure is formed inside the fixed cylinder 406, and the rubber product at the bottom can be adsorbed through the suction flow channel inside 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 that the rubber product in the lower mold seat 208 can be taken out by the adsorption force. During this process, when the adsorption plate 407 moves upward, it will also drive the guide column 604 at the upper end of the valve core 603 to be inserted into the guide sleeve 606 on the upper part of the fixed frame 605.At this time, as the valve core 603 rotates, the inside of the valve housing 601 can be automatically blocked to prevent the cooling water from flowing. Finally, when the spring seat 401 drives the door frame 403 to move upward through the guide plate 402, the one-way valve 405 will contact the sealing rod 502. At the same time, the compression spring 503 is used to make the subsequent sealing rod 502 always close to the one-way valve 405 to block it. When the spring seat 401 is reset, the second lifting frame 408 will contact the magnetic column 501. When the moving seat 204 moves to the middle of the bottom frame 1, it will push the stopper 505, the stopper 505 will slide upward under the limit of the slider 506, thereby driving the door frame 403 to move down a short distance through the rotating plate 504. At this time, the magnetic column 501 will absorb the second lifting frame 408 to fix the position of the fixed cylinder 406, and the piston rod 404 will first slide inside the fixed cylinder 406, thereby increasing the air pressure inside the fixed cylinder 406, so that the adsorption plate 407 will not be adsorbed. The rubber product will fall to the conveyor belt below under the action of gravity, and the rubber product after unloading will be automatically transported.
