Description

Technical Field

[0001] The present invention relates to the field of vulcanizers, and particularly to a fully automatic vulcanizer for bearing seals. Background Art

[0002] Rubber vulcanization refers to keeping rubber at a certain temperature and pressure for a certain period of time under heat and pressure, causing chemical reactions among rubber macromolecules to generate cross-linking, converting unvulcanized rubber compound into vulcanized rubber, thereby endowing rubber with better physical properties. Currently, bearing seals are obtained as finished products through vulcanization by a vulcanizer. The specific process is as follows: 1. Place a skeleton (a ring made of steel) into a mold; 2. Place rubber material on the skeleton; 3. Close the mold and push it into the vulcanizer to keep it warm and pressurized for a certain period of time; 4. Open the mold to take out the product and tear off the waste edges. Although there are many types of current vulcanizers, even the vulcanizers with a high degree of automation currently only have the function of automatically opening and closing the mold. The operations of feeding the skeleton, feeding the rubber material, and discharging the finished product all rely on manual labor, with a very low degree of automation and low production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic vulcanizer to achieve automatic feeding of the skeleton, automatic feeding of rubber, automatic discharging of the finished product, and automatic trimming, thereby improving the production efficiency of bearing seals.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: a fully automatic vulcanizer for bearing seals, including a frame, a vulcanizer body, a truss assembly, a mold assembly, and a blanking assembly;

[0005] The truss assembly includes a horizontal truss and a first fixture assembly. The horizontal truss is fixed on the frame, and the first fixture assembly is installed on the horizontal truss;

[0006] The mold assembly is connected to the vulcanizer body, and the vulcanizer body belongs to the prior art;

[0007] The blanking component includes a blanking tooling, a rubber scraping plate, and a finished product collecting rod; the blanking tooling includes a blanking upper template, a blanking lower template, a first guiding shaft, a first spring, a first clamping rod, and a ramming column. The first clamping rod and the first guiding shaft are both fixed on the blanking lower template. The first spring is sleeved on the first guiding shaft. The blanking upper template is sleeved on the first guiding shaft and can move up and down along the first guiding shaft. When the blanking upper template moves downward close to the blanking lower template, the first spring will be compressed; multiple finished product through holes are provided on the surface of the rubber scraping plate. The number of finished product collecting rods is the same as that of the finished product through holes. The rubber scraping plate and the finished product collecting rods are both fixed on the frame. The finished product collecting rods correspond to the finished product through holes one by one and are concentric. The diameter of the finished product collecting rod is equal to the inner diameter of the finished product sealing ring, and the diameter of the finished product through hole is equal to the outer diameter of the finished product sealing ring; multiple groups of blanking holes are provided on the bottom surface of the blanking lower template. Each group of blanking holes corresponds to a finished product through hole. Each group of blanking holes includes at least two blanking through holes and two blanking blind holes. Magnets are installed in all the blanking blind holes. Each group of blanking holes is arranged in a ring shape of the finished product sealing ring; a ramming column is provided on the bottom surface of the blanking upper template. The ramming column corresponds to the blanking through holes one by one;

[0008] When the full-automatic vulcanizing machine of the present invention is working, the first clamping component can clamp the blanking tooling to move back and forth between the mold opening station and the blanking station to achieve automatic blanking and trimming. The specific working process is as follows: 1. The first clamping component clamps the blanking tooling and moves it to the mold opening station; 2. The magnets in the blanking blind holes adsorb the finished product sealing rings in the mold component; 3. The first clamping component clamps the blanking tooling and moves it to the blanking station, so that the blanking tooling is located directly above the finished product collecting rod; 4. The first clamping component drives the blanking upper template to move downward. The ramming column moves downward along with the blanking upper template. The ramming column enters the blanking through hole to press the finished product sealing ring into the finished product through hole and sleeve it on the finished product collecting rod. At the same time, the edge of the finished product through hole trims off the waste edges around the finished product sealing ring.

[0009] In order to avoid too much waste edge accumulating on the rubber scraping plate, the present invention further includes a rubber scraping type degumming mechanism. The rubber scraping type degumming mechanism includes a scraping plate, a degumming track, and a slider. The slider is installed on the degumming track, and the scraping plate is installed on the slider. The bottom edge of the scraping plate is at the same height as the upper surface of the rubber scraping plate; at regular intervals, the slider drives the scraping plate to move back and forth along the degumming track once to scrape off the waste edges accumulated on the surface of the rubber scraping plate by using the scraping plate. The waste edges accumulated on the rubber scraping plate can also be removed by using a jet degumming mechanism. The jet degumming mechanism includes a nozzle and an air pump. The nozzle is connected to the air pump. The nozzle points to the upper surface of the rubber scraping plate. The airflow generated by the nozzle can also blow off the waste edges accumulated on the rubber scraping plate.

[0010] Further, a horizontal track and a horizontal rack are provided on the horizontal truss. The first fixture assembly includes a moving plate, a first motor, a gear, a base plate, a first cylinder, a chuck, a second cylinder, a second motor, and a cross bar. The moving plate is installed on the horizontal track, and the first motor is installed on the moving plate. The rotating shaft of the first motor is connected to the gear, and the gear meshes with the horizontal rack. When the first motor drives the gear to rotate, the entire first fixture assembly will move horizontally along the horizontal track. The first cylinder is vertically installed on the moving plate, and the base plate is connected to the telescopic rod of the first cylinder. Both the chuck and the second cylinder are installed on the base plate. The chuck should correspond to the position of the first clamping rod, and the chuck is used to clamp the first clamping rod. The second motor is connected to the telescopic rod of the second cylinder, and the cross bar is connected to the rotating shaft of the second motor. The first cylinder is used to drive the base plate and the chuck to move up and down. When the chuck clamps the first clamping rod, the entire blanking tooling will also move up and down with the base plate. The second cylinder is used to drive the cross bar to move up and down. When the chuck clamps the first clamping rod, the cross bar moving up and down can press down the blanking upper template.

[0011] Further, the fully automatic vulcanizing machine further includes a skeleton loading assembly. The skeleton loading assembly includes a lifting mechanism, a lifting plate, a stringing rod, and a skeleton loading tooling. The lifting mechanism drives the lifting plate to move up and down. A circular through hole is provided on the surface of the lifting plate, and the stringing rod passes through the circular through hole. The diameter of the stringing rod is equal to the inner diameter of the skeleton, and the diameter of the circular through hole is smaller than the outer diameter of the skeleton. In application, the skeletons (many skeletons), which are one of the raw materials for bearing seals, are pre-sleeved on the stringing rods in advance. The skeletons themselves rest on the lifting plate. The function of the lifting plate is to lift the skeletons. When the topmost skeleton is taken away, the lifting plate will lift a certain distance to ensure that the next skeleton waiting to be taken is always at the designated height.

[0012] The skeleton loading tooling includes a skeleton upper template, a magnetic plate, a skeleton lower template, a second guide shaft, a second spring, a second clamping rod, and a lifting plate. The magnetic plate is fixed on the lower surface of the skeleton upper template. Both the second clamping rod and the second guide shaft are fixed on the skeleton lower template. The second spring is sleeved on the second guide shaft, and the skeleton upper template is sleeved on the second guide shaft. The skeleton upper template, the magnetic plate, and the skeleton lower template are attached in sequence, and the second spring presses on the upper surface of the skeleton upper template. The lifting plate is fixed on the skeleton upper template. An annular groove for accommodating the skeleton is provided on the surface of the skeleton lower template, and the annular grooves correspond to the stringing rods one by one.

[0013] The skeleton loading component is used to achieve automatic loading of the skeleton for full-automatic vulcanization. The skeleton loading tooling also shuttles between the mold opening station and the skeleton loading station after being clamped by the first fixture component. The specific working process is as follows: 1. The chuck in the first fixture component clamps the second clamping rod. The first fixture component drives the skeleton loading tooling to move directly above the stringing rod. The uppermost skeleton on the stringing rod is embedded in the annular groove on the bottom surface of the skeleton lower template, and this uppermost skeleton is adsorbed by the magnetic plate attached to the skeleton upper template; 2. The first fixture component drives the skeleton loading tooling to move to the mold opening station; 3. The second cylinder and the second motor in the first fixture component cooperate to make the cross bar rotate and move and then horizontally insert under the lifting plate; 4. The second cylinder drives the cross bar to rise, driving the lifting plate, the skeleton upper template, and the magnetic plate to rise. The distance between the magnetic plate and the skeleton lower template increases, and the magnetic plate loses the adsorption effect on the skeleton, and the skeleton naturally falls into the mold component.

[0014] Furthermore, the full-automatic vulcanizer further includes a granule loading component. The granule loading component includes a granule feeding mechanism, a granule loading tooling, a pallet, and a linear vibrator. The pallet is installed on the linear vibrator, the granule loading tooling is placed on the pallet, and the granule feeding mechanism supplies rubber granules to the granule loading tooling;

[0015] The granule loading tooling includes a granule upper template, a granule lower template, a third clamping rod, and a connecting pin. The granule upper template is provided with a plurality of waist-shaped holes and first granule holes. The granule lower template is provided with a plurality of round holes and second granule holes. The first granule holes and the second granule holes are both matched with the size of the rubber granules. The waist-shaped holes correspond to the round holes one by one, and the first granule holes correspond to the second granule holes one by one; The connecting pin passes through the waist-shaped holes and the round holes and connects the granule upper template and the granule lower template; The third clamping rod is fixed on the granule upper template;

[0016] Since the granule upper template uses waist-shaped holes corresponding to the round holes of the granule lower template one by one, the granule upper template can generate a horizontal displacement relative to the granule lower template, thereby realizing the dislocation of the first granule holes and the second granule holes;

[0017] The granule feeding assembly is used to achieve automatic feeding of rubber granules for a full-automatic vulcanizer. The granule feeding tooling can also be clamped by the first fixture assembly and move back and forth between the mold opening station and the granule feeding station. The specific working process is as follows: 1. The first fixture assembly places the granule feeding tooling on the pallet, and at this time, the first granule holes and the second granule holes are misaligned; 2. The granule feeding mechanism throws a large number of granule rubbers onto the surface of the granule upper template. At the same time, the linear vibrator drives the pallet and the granule feeding tooling to vibrate, so that each first granule hole on the surface of the granule upper template contains a rubber granule. Since the first granule holes and the second granule holes are misaligned at this time, the rubber granules will not enter the second granule holes; 3. The first fixture assembly moves the granule feeding tooling to the mold opening station and drives the granule upper template to move horizontally relative to the granule lower template, so that the first granule holes and the second granule holes are aligned, and the rubber granules stored in the first granule holes will fall along the second granule holes and enter the mold assembly.

[0018] Further, the granule feeding mechanism includes a vibrating bowl and a door stop. Rubber granules are stored in the vibrating bowl, and the door stop is installed at the discharge port of the vibrating bowl; when the vibrating bowl starts to vibrate, the rubber granules in the vibrating bowl continuously fall from the discharge port to the granule upper template, and the door stop is used to realize the opening and closing of the discharge port of the vibrating bowl.

[0019] For the full-automatic vulcanizer of the present invention, although the blanking tooling, the skeleton feeding tooling, and the granule feeding tooling can all use the first fixture assembly to move positions, this will affect the working efficiency because the blanking work and the feeding work can be carried out simultaneously. To improve the working efficiency, the present invention further includes a second fixture assembly. The second fixture assembly is installed on the horizontal truss, and the second fixture assembly is the same as the first fixture assembly that deletes the second cylinder, the second motor, and the cross bar; this means that in the present invention, the blanking tooling and the skeleton feeding tooling share the first fixture assembly, and the granule feeding tooling uses the second fixture assembly alone; considering that the second cylinder, the second motor, and the cross bar in the first fixture assembly are not required during the working process of the granule feeding tooling, therefore, the difference between the second fixture assembly and the first fixture assembly is only that the second cylinder, the second motor, and the cross bar are deleted.

[0020] Further, the mold assembly includes a mold driving cylinder, an upper mold, a lower mold, a hinge, a mold track, and a mold opening and closing mechanism. The upper mold and the lower mold are connected by a hinge. The mold driving cylinder drives the upper mold and the lower mold to move horizontally along the mold track. The mold driving cylinder is mainly used to drive the upper mold and the lower mold to move back and forth between the vulcanizer body and the mold opening station. The mold opening and closing mechanism drives the upper mold to flip to realize mold opening and closing; positioning pins are arranged on the surface of the lower mold, and pin holes are arranged on the granule lower template. When the granule feeding tooling is placed on the granule lower template, the positioning pins are inserted into the pin holes, and then the granule upper template can translate relative to the granule lower template.

[0021] Furthermore, the mold assembly further includes a jacking mechanism and ejector pins. The lower mold is provided with pin holes, and the ejector pins are located directly below the pin holes. The jacking mechanism drives the ejector pins to move up and down. When the finished sealing ring is in the lower mold after mold opening, the ejector pins are used to eject the finished sealing ring.

[0022] The mold opening and closing mechanism includes guide wheels and vertical plates. The guide wheels are installed on both sides of the upper mold, and the vertical plates are located on both sides of the upper mold. The vertical plates are provided with upwardly curved guide grooves. The lower openings of the guide grooves are located on the movement paths of the guide wheels. The mold opening and closing mechanism in the present invention is a passive mechanism and does not have power itself. When the mold driving cylinder drives the upper mold and the lower mold to move to the mold opening station, the guide wheels are driven to move obliquely upward in the arc-shaped grooves, thereby causing the upper mold to be opened passively.

[0023] Beneficial effects: (1) The fully automatic vulcanizing machine for bearing sealing rings of the present invention uses a blanking tooling to achieve the grasping and releasing of the finished sealing rings, and cooperates with the finished product receiving rod and the first fixture assembly to realize the automatic blanking and automatic trimming of the vulcanizing machine, improving the production efficiency of the bearing sealing rings. (2) The fully automatic vulcanizing machine for bearing sealing rings of the present invention is equipped with a scraping type degumming mechanism for the scraping plate, regularly removing the waste edges accumulated on the surface of the scraping plate to avoid affecting the production of the bearing sealing rings. (3) The fully automatic vulcanizing machine for bearing sealing rings of the present invention uses a skeleton feeding tooling to achieve the grasping and releasing of the skeletons, and cooperates with the stringing rod and the first fixture assembly to realize the automatic feeding of the skeletons, improving the automation degree of the vulcanizing machine. (4) The fully automatic vulcanizing machine for bearing sealing rings of the present invention uses a granule feeding tooling and a linear vibrator to realize the automatic loading and feeding of rubber granules, ensuring that a quantitative amount of rubber granules can be accurately and quickly placed into each mold cavity of the mold assembly, improving the production efficiency of the bearing sealing rings.

Detailed implementation manners

[0043] The present invention will be further described in detail below in conjunction with the detailed implementation manners.

[0044] Embodiment 1

[0045] As Figure 1 and Figure 2 shown, the full-automatic vulcanizer for bearing seals of this embodiment includes a frame 100, a vulcanizer body 200, a truss assembly 300, a mold assembly 400, a blanking assembly 500, a skeleton feeding assembly 600, and a particle feeding assembly 700;

[0046] As Figures 3 to 5As shown in the figure, the truss assembly 300 includes a horizontal truss 310, a first fixture assembly 320, and a second fixture assembly 330. The horizontal truss 310 is fixed on the frame 100. A horizontal track 311 and a horizontal rack 312 are provided on the horizontal truss 310. The first fixture assembly 320 includes a moving plate 321, a first motor 322, a gear, a base plate 323, a first cylinder 324, a chuck 325, a second cylinder 326, a second motor 327, and a cross bar 328. The moving plate 321 is installed on the horizontal track 311. The first motor 322 is installed on the moving plate 321. The rotating shaft of the first motor 322 is connected to the gear, and the gear meshes with the horizontal rack 312. When the first motor 322 drives the gear to rotate, the entire first fixture assembly 320 will move horizontally along the horizontal track 311. The first cylinder 324 is vertically installed on the moving plate 321, and the base plate 323 is connected to the telescopic rod of the first cylinder 324. Both the chuck 325 and the second cylinder 326 are installed on the base plate 323. The second motor 327 is connected to the telescopic rod of the second cylinder 326, and the cross bar 328 is connected to the rotating shaft of the second motor 327. The second fixture assembly 330 is installed on the horizontal truss 310, and the second fixture assembly 330 is the same as the first fixture assembly 320 after removing the second cylinder 326, the second motor 327, and the cross bar 328.

[0047] As Figures 6 to 9 shown, the particle feeding assembly 700 includes a particle feeding mechanism 710, a particle feeding tooling 720, a pallet 730, and a linear vibrator 740. The pallet 730 is installed on the linear vibrator 740, and the particle feeding tooling 720 is placed on the pallet 730.

[0048] The particle feeding tooling 720 includes a particle upper template 721, a particle lower template 722, a third clamping rod 723, and a connecting pin 724. The particle upper template 721 is provided with a plurality of waist-shaped holes 721-1 and first particle holes 721-2. The particle lower template 722 is provided with a plurality of round holes 722-1 and second particle holes 722-2. Both the first particle holes 721-2 and the second particle holes 722-2 match the size of the rubber particles. The waist-shaped holes 721-1 correspond to the round holes 722-1 one by one, and the first particle holes 721-2 correspond to the second particle holes 722-2 one by one. The connecting pin 724 passes through the waist-shaped holes 721-1 and the round holes 722-1 and connects the particle upper template 721 and the particle lower template 722. The third clamping rod 723 is fixed on the particle upper template 721. Since the particle upper template 721 uses the waist-shaped holes 721-1 corresponding to the round holes 722-1 of the particle lower template 722 one by one, the particle upper template 721 can generate a horizontal displacement relative to the particle lower template 722, thereby realizing the dislocation of the first particle holes 721-2 and the second particle holes 722-2. A pin hole 722-3 is provided at the bottom of the particle lower template 722.

[0049] As Figure 2 shown, the particle feeding mechanism 710 includes a vibrating disk 711 and a door stop. Rubber particles are stored in the vibrating disk 711, and the door stop is installed at the discharge port of the vibrating disk 711. When the vibrating disk 711 starts vibrating, the rubber particles in the vibrating disk 711 continuously fall from the discharge port to the particle upper template 721, and the door stop is used to realize the opening and closing of the discharge port of the vibrating disk 711;

[0050] As Figure 2 、 Figure 10 and Figure 11 shown, the mold assembly 400 includes a mold driving cylinder 410, an upper mold 420, a lower mold 430, a hinge 440, a mold track 450, a mold opening and closing mechanism 460, a jacking mechanism 470 and a ejector pin 480. The upper mold 420 and the lower mold 430 are connected by the hinge 440. The mold driving cylinder 410 drives the upper mold 420 and the lower mold 430 to move horizontally along the mold track 450. The mold driving cylinder 410 is mainly used to drive the upper mold 420 and the lower mold 430 to move back and forth between the vulcanizer body 200 and the mold opening station. The mold opening and closing mechanism 460 drives the upper mold 420 to flip to realize mold opening and closing; A positioning pin 431 is provided on the surface of the lower mold 430;

[0051] The lower mold 430 is provided with a pin hole 432. The ejector pin 480 is located directly below the pin hole 432, and the jacking mechanism 470 drives the ejector pin 480 to move up and down; When the finished sealing ring is in the lower mold 430 after mold opening, the ejector pin 480 is used to eject the finished sealing ring;

[0052] The mold opening and closing mechanism 460 includes a guide wheel 461 and a vertical plate 462. The guide wheel 461 is installed on both sides of the upper mold 420, and the vertical plate 462 is located on both sides of the upper mold 420. An upwardly curved guide groove 462-1 is provided on the vertical plate 462. The lower opening of the guide groove 462-1 is located on the movement path of the guide wheel 461. The mold opening and closing mechanism 460 in this embodiment is a passive mechanism and does not have its own power. When the mold driving cylinder 410 drives the upper mold 420 and the lower mold 430 as Figure 10 shown to move along the mold track 450, the guide wheel 461 moves obliquely upward passively in the arc groove, thereby causing the upper mold 420 to be opened passively; When moving in the reverse direction, the upper mold 420 is closed passively;

[0053] As Figures 12 to 15As shown in the figure, the skeleton feeding assembly 600 includes a lifting mechanism 610, a lifting plate 620, a stringing rod 630, and a skeleton feeding tooling 640. The lifting mechanism 610 drives the lifting plate 620 to move up and down. A circular through-hole is provided on the surface of the lifting plate 620, and the stringing rod 630 passes through the circular through-hole. The diameter of the stringing rod 630 is equal to the inner diameter of the skeleton, and the diameter of the circular through-hole is smaller than the outer diameter of the skeleton. In application, the skeleton, which is one of the raw materials for the production of bearing seals, is pre-sleeved on the stringing rod 630, and the skeleton itself lies on the lifting plate 620. The function of the lifting plate 620 is to lift the skeleton. When the topmost skeleton is taken away, the lifting plate 620 will lift a certain distance to ensure that the next skeleton waiting to be taken is always at the specified height;

[0054] The skeleton feeding tooling 640 includes a skeleton upper template 641, a magnetic plate 642, a skeleton lower template 643, a second guide shaft 644, a second spring, a second clamping rod 645, and a lifting plate 646. The magnetic plate 642 is fixed on the lower surface of the skeleton upper template 641. Both the second clamping rod 645 and the second guide shaft 644 are fixed on the skeleton lower template 643. The second spring is sleeved on the second guide shaft 644( Figure 13 and Figure 15 (the second spring is not shown in the figure), the skeleton upper template 641 is sleeved on the second guide shaft 644. The skeleton upper template 641, the magnetic plate 642, and the skeleton lower template 643 are attached to each other in sequence, and the second spring presses on the upper surface of the skeleton upper template 641. The lifting plate 646 is fixed on the skeleton upper template 641. An annular groove 643-1 for accommodating the skeleton is provided on the surface of the skeleton lower template 643, and the annular groove 643-1 corresponds to the stringing rod 630 one by one;

[0055] As Figures 16 to 18 shown in the figure, the blanking assembly 500 includes a blanking tooling 510, a glue scraping plate 520, a finished product collecting rod 530, and a glue scraping type degumming mechanism 540. The blanking tooling 510 includes a blanking upper template 511, a blanking lower template 512, a first guide shaft 513, a first spring, a first clamping rod 514, and a ram 515. Both the first clamping rod 514 and the first guide shaft 513 are fixed on the blanking lower template 512. The first spring is sleeved on the first guide shaft 513( Figure 16(The first spring is not shown in the figure). The blanking upper template 511 is sleeved on the first guiding shaft 513 and can move up and down along the first guiding shaft 513. When the blanking upper template 511 moves downward close to the blanking lower template 512, the first spring will be compressed; a plurality of finished product through holes 521 are arranged on the surface of the glue scraping plate 520. The number of the finished product receiving rods 530 is the same as that of the finished product through holes 521. Both the glue scraping plate 520 and the finished product receiving rods 530 are fixed on the frame 100. The finished product receiving rods 530 and the finished product through holes 521 correspond to each other one by one and are concentric. The diameter of the finished product receiving rod 530 is equal to the inner diameter of the finished product sealing ring, and the diameter of the finished product through hole 521 is equal to the outer diameter of the finished product sealing ring; a plurality of groups of blanking holes are arranged on the bottom surface of the blanking lower template 512.

The slider 543 is installed on the degumming track 542, and the scraping plate 541 is installed on the slider 543. The bottom edge of the scraping plate 541 is at the same height as the upper surface of the glue scraping plate 520; at regular intervals, the slider 543 drives the scraping plate 541 to reciprocate along the degumming track 542 once, and uses the scraping plate 541 to scrape off the waste edges accumulated on the surface of the glue scraping plate 520.

[0057] The full-automatic vulcanizing machine for bearing sealing rings in this embodiment is used for the full-automatic production of bearing sealing rings. The raw materials are a skeleton and rubber particles. The rubber particles are stored in a Figure 2 shown vibrating disk 711, and the raw material skeleton is sleeved on a Figure 12 shown stringing rod 630. The basic working process is as follows:

[0058] (1) As shown in Figure 3 and Figure 4 , the first fixture assembly 320 moves to directly above the skeleton loading tooling 640 as shown in Figure 12 . The chuck 325 in the first fixture assembly 320 clamps the second clamping rod 645 in the skeleton loading tooling 640;

[0059] (2) The skeleton at the top layer of the stringing rod 630 is embedded in the annular groove 643-1 on the bottom surface of the skeleton lower template 643 as shown in Figure 14 . This top-layer skeleton is adsorbed by the magnetic plate 642 attached to the skeleton upper template 641;

[0060] (3) The first fixture assembly 320 drives the skeleton loading tooling 640 to move to directly above the lower die 430 as shown in Figure 11 the figure;

[0061] (4) As shown in Figure 4 the figure, the second cylinder 326 and the second motor 327 in the first fixture assembly 320 cooperate to act, so that after the cross bar 328 rotates and moves, it is horizontally inserted under the lifting plate 646 as shown in Figure 15 the figure. Then the second cylinder 326 drives the cross bar 328 to rise, driving the lifting plate 646, the skeleton upper template 641 and the magnetic plate 642 to rise. The distance between the magnetic plate 642 and the skeleton lower template 643 increases, and the magnetic plate 642 loses the adsorption effect on the skeleton, and the skeleton naturally falls into the lower die 430 as shown in Figure 11 the figure;

[0062] (5) The first fixture assembly 320 returns the skeleton loading tooling 640 to its original position;

[0063] (6) The second fixture assembly 330 places the particle loading tooling 720 on the pallet 730 as shown in Figure 6 the figure. At this time, the first particle hole 721-2 and the second particle hole 722-2 are misaligned;

[0064] (7) As shown in Figure 2 the figure, the vibrating disk 711 vibrates and throws a large number of granular rubbers onto the surface of the particle upper template 721. At the same time, as shown in Figure 6 the figure, the linear vibrator 740 drives the pallet 730 and the particle loading tooling 720 to vibrate, so that each first particle hole 721-2 on the surface of the particle upper template 721 contains a rubber particle. Since the first particle hole 721-2 and the second particle hole 722-2 are misaligned at this time, the rubber particles will not enter the second particle hole 722-2;

[0065] (8) The second fixture assembly 330 moves the particle loading tooling 720 to directly above the lower die 430 as shown in Figure 11 the figure. The positioning pin 431 as shown in Figure 11 is inserted into the pin hole 722-3 as shown in Figure 9 the figure. Then the second fixture assembly 330 drives the particle upper template 721 to generate a horizontal movement relative to the particle lower template 722, so that the first particle hole 721-2 is aligned with the second particle hole 722-2. The rubber particles stored in the first particle hole 721-2 will fall along the second particle hole 722-2 and enter the lower die 430 as shown in Figure 11 the figure;

[0066] (9) The second fixture assembly 330 returns the particle loading tooling 720 to its original position;

[0067] (10) As shown in Figure 2 , the mold driving cylinder 410 drives the upper mold 420 and the lower mold 430 shown in Figure 10 to retract and finally enter the vulcanizer body 200. During the retraction process, the upper mold 420 automatically closes;

[0068] (11) The vulcanizer body 200 keeps the upper mold 420 and the lower mold 430 at a constant temperature and pressure for a certain period of time, and then as shown in Figure 2 , the mold driving cylinder 410 drives the upper mold 420 and the lower mold 430 shown in Figure 10 to come out along the mold track 450 again. The guide wheel 461 moves obliquely upward passively in the arc groove, thereby causing the upper mold 420 to open passively; at this time, there are multiple processed finished product sealing rings in the lower mold 430;

[0069] (12) As shown in Figure 10 , the lifting mechanism 470 drives the ejector pin 480 to move upward. The ejector pin 480 passes through the ejector pin hole 432 shown in Figure 11 , and the ejector pin 480 ejects the finished product sealing ring;

[0070] (13) The first fixture assembly 320 clamps the blanking tooling 510 and moves to directly above the lower mold 430 shown in Figure 11 . The magnet in the blanking blind hole 512-2 shown in Figure 18 adsorbs the finished product sealing ring in the mold assembly 400;

[0071] (14) The first fixture assembly 320 clamps the blanking tooling 510 and moves to directly above the finished product receiving rod 530 shown in Figure 16 . The second cylinder 326 in the first fixture assembly 320 shown in Figure 4 drives the cross bar 328 to move downward and press down the blanking upper template 511 shown in Figure 18 . The ram 515 moves downward along with the blanking upper template 511. The ram 515 enters the blanking through hole 512-1 and presses the finished product sealing ring into the finished product through hole 521 shown in Figure 17 and slews on the finished product receiving rod 530. The edge of the finished product through hole 521 simultaneously trims the waste edge around the finished product sealing ring.
