Technical Field

[0001] The utility model relates to the technical field of sealing ring production, in particular to a sealing ring production and forming device with an ejection and demoulding structure. Background Technique

[0002] Sealing rings are very common in life and are mostly used at pipe joints, valve core joints, or in the process of transporting gases and liquids. They are not only indispensable tools in life but also in industrial production. Sealing rings are made of rubber materials and have good ductility and water resistance.

[0003] In the prior art, the design of the die clamping process for molds is relatively complex and there are easy gaps in die clamping. Using for too long will cause large burrs on the finished products, affecting the production efficiency.

[0004] In order to overcome the above defects, the prior art (Chinese patent with application number: CN113844080A, application date: September 22, 2021) discloses a sealing ring production device and method for pipelines; when producing a sealing ring, materials are put into the inside of the mixing tank through a feeding pipe; then the mixing component is started to stir and mix the raw materials inside the mixing tank evenly; the mixed raw materials are injected into the constant temperature tank through an injection pipe, and the rotating component inside the constant temperature tank is started to stir the mixed raw materials again to make them mix more evenly; then the sealing ring mold is placed on the conveyor belt. When the sealing ring mold is conveyed to the discharge pipe arranged below the constant temperature tank, the evenly mixed raw materials are injected into the sealing ring mold; the conveyor belt conveys it to the pressing component for pressing to flatten the surface of the sealing ring mold, and then it is dried and left standing, and a sealing ring with better sealing performance can be obtained.

[0005] Although the prior art can solve the above problems, the discharging structure of the finished product is too complex, or it only relies on manual discharging, which has a great impact on production efficiency, and the just-produced sealing ring is too hot to be suitable for the manual discharging method. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sealing ring production and forming device with an ejection and demoulding structure to solve the problems of too complex discharging structure of the finished product, relying on manual discharging, great impact on production efficiency, and the just-produced sealing ring being too hot to be suitable for other discharging methods as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A sealing ring production and forming device with an ejection and demolding structure, including a support frame installed above the base, and a push-pull motor installed above the support frame. The output direction of the push-pull motor is installed with a touch rod, and a pressure plate is installed on the surface of the touch rod, and the pressure plate is fixedly connected to the touch rod. In front of the pressure plate, a first mold clamping is installed, and a through hole is opened on the left side of the first mold clamping. The touch rod passes through the through hole, and rollers are installed at the bottom of the first mold clamping. A third inner groove is opened on the surface of the base, and rollers are installed above the third inner groove. Spring rods are installed on both side surfaces of the first mold clamping, and a fifth inner groove is opened at the top of the first mold clamping. A second forming inner groove is opened on the surface of the first mold clamping, and a second mold clamping is installed in front of the first mold clamping. A first forming inner groove is opened on the surface of the second mold clamping, and a first inner groove is opened inside the first forming inner groove. A trigger-type demolding mechanism is installed inside the first inner groove. The trigger-type demolding mechanism includes a top block. An eighth inner groove is opened inside the second inner groove, and a top block is installed inside the eighth inner groove. A transmission wire group is installed behind the top block, and the other end of the transmission wire group is installed at the end of the demolding rod. A second spring is installed behind the demolding rod, and a limiting block is installed on the right side of the second spring;

[0008] Above the first inner groove, a sixth inner groove is opened, and a secondary fixing mechanism for the first mold clamping and the second mold clamping is arranged inside the sixth inner groove.

[0009] Further, the secondary fixing mechanism includes a fixing rod, and the lower part of the fixing rod passes through the sixth inner groove and is on the movement track of the demolding rod. Seventh inner grooves are opened on both sides of the sixth inner groove.

[0010] Further, a first spring is installed inside the seventh inner groove, and both ends of the demolding rod are installed above the first spring. The top end of the fixing rod passes through the fourth inner groove, and the top end of the fourth inner groove corresponds to the lower surface of the fifth inner groove.

[0011] Further, the surface of the roller and the upper surface of the third inner groove form a sliding structure, and the pressure plate contacts the left surface of the second mold clamping through the right surface of the first mold clamping to form a transmission structure.

[0012] Further, the first mold clamping contacts both side surfaces of the second mold clamping through the front end of the spring rod to form an elastic structure, and the bottom surface of the second mold clamping is fixed above the base. The right surface of the first mold clamping and the left surface of the second mold clamping are nested and installed.

[0013] Further, the touch rod forms a transmission structure through the fixed connection of the end of the top block and the transmission wire group, and the transmission wire group forms an elastic structure through the contact of the end of the demolding rod and the second spring.

[0014] Further, the sixth inner groove forms an elastic structure by contacting the lower surface of the first spring with both ends of the fixed rod, and the lower end of the fixed rod is designed to be inclined.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sealing ring production and forming device provided with an ejection and demoulding structure uses the forward push of the trigger rod to touch the top block, and pushes the transmission wire group connected to the end inward along the eighth inner groove, so that the demoulding rod connected to the end of the transmission wire group compresses the second spring to move inward. After the forming work of the sealing ring is completed, due to the limit block installed at the end of the second spring, the second spring resets again and pushes the demoulding rod back to its original position along the first inner groove, completing the automatic ejection function after the production of the sealing ring;

[0016] Further, when the demoulding rod moves inward, the end will contact the lower end of the fixed rod. Since the lower end of the fixed rod is designed to be inclined, the upper surface of the demoulding rod pushes the fixed rod to slide upward along the sixth inner groove. While sliding, both sides of the fixed rod press the first spring to eject outward and pass through the fourth inner groove into the fifth inner groove, completing the secondary fixation between the molds and effectively preventing the loosening between the molds;

[0017] Further, the push-pull motor pushes the first mold closing through the pressure plate to make the roller slide forward inside the third inner groove, and the spring rod passes through both sides of the second mold closing, so that the mold can be automatically opened and closed after the production of the sealing ring.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figures 1-7 , the present invention provides the following technical solutions: A sealing ring production and forming device with an ejection and demolding structure, including a base 1, a support frame 2 and a first inner groove 28.

[0028] A support frame 2 is installed above the base 1, and a push-pull motor 3 is installed above the support frame 2. A trigger rod 5 is installed in the output direction of the push-pull motor 3, and a pressure plate 4 is installed on the surface of the trigger rod 5. Moreover, the pressure plate 4 is fixedly connected to the trigger rod 5. A first mold closing 6 is installed in front of the pressure plate 4, and a perforation 7 is opened on the left side of the first mold closing 6. The trigger rod 5 passes through the perforation 7, and a roller 13 is installed at the bottom of the first mold closing 6. A third inner groove 12 is opened on the surface of the base 1, and a roller 13 is installed above the third inner groove 12. Spring rods 8 are installed on both sides of the first mold closing 6, and a fifth inner groove 17 is opened at the top of the first mold closing 6. A second forming inner groove 18 is opened on the surface of the first mold closing 6, and a second mold closing 27 is installed in front of the first mold closing 6. A first forming inner groove 11 is opened on the surface of the second mold closing 27, and a first inner groove 28 is opened inside the first forming inner groove 11. A trigger type demolding mechanism is installed inside the first inner groove 28. The trigger type demolding mechanism includes a top block 14. An eighth inner groove 25 is opened inside the second inner groove 10, and a top block 14 is installed inside the eighth inner groove 25. A transmission line group 24 is installed behind the top block 14, and the other end of the transmission line group 24 is installed at the end of the demolding rod 15. A second spring 22 is installed behind the demolding rod 15, and a limit block 26 is installed on the right side of the second spring 22;

[0029] Above the first inner groove 28, a sixth inner groove 19 is provided, and inside the sixth inner groove 19, a secondary fixing mechanism for the first mold clamping 6 and the second mold clamping 27 is provided.

[0030] As Figure 1 , Figure 2 , Figure 4 , Figure 7 In the technical solution shown, to solve the problem that the finished product cannot be automatically ejected after production, it is disclosed that: the surface of the roller 13 and the upper surface of the third inner groove 12 form a sliding structure, and the pressure plate 4 contacts the left surface of the second mold clamping 27 through the right surface of the first mold clamping 6 to form a transmission structure. The front end of the spring rod 8 of the first mold clamping 6 contacts the two side surfaces of the second mold clamping 27 to form an elastic structure, and the bottom surface of the second mold clamping 27 is fixed above the base 1. The right surface of the first mold clamping 6 and the left surface of the second mold clamping 27 are nested. The trigger rod 5 forms a transmission structure through the fixed connection of the end of the top block 14 and the transmission line group 24, and the transmission line group 24 forms an elastic structure through the contact of the end of the demolding rod 15 with the second spring 22.

[0031] When manufacturing the sealing ring, first turn on the push-pull motor 3 installed on the support frame 2. The trigger rod 5 in the output direction of the push-pull motor 3 will move forward, causing the pressure plate 4 to push the first mold clamping 6 forward. At this time, the roller 13 will slide along the inside of the third inner groove 12, and the spring rod 8 will slowly pass through the inside of the reset top frame 9 corresponding to the side surface of the second mold clamping 27 until the first forming inner groove 11 and the second forming inner groove 18 completely coincide. Since the second mold clamping 27 is fixed on the base 1, while the pressure plate 4 moves forward, the trigger rod 5 passes through the through hole 7 and moves into the inside of the second inner groove 10, and touches the top block 14. The top block 14 slides inward along the eighth inner groove 25, and the two groups of transmission line groups 24 connected to the end contract along the moving direction of the top block 14 together, driving the demolding rod 15 connected to the end of the transmission line group 24 to press the second spring 22 inward to retract along the first inner groove 28.

[0032] As Figure 3 , Figure 5 , Figure 6 In the technical solution shown, to solve the problem that the mold cannot be completely sealed well only by the push-pull motor 3, it is disclosed that: the secondary fixing mechanism includes a fixing rod 20, and the lower part of the fixing rod 20 passes through the sixth inner groove 19 and is on the movement track of the demolding rod 15. The seventh inner grooves 23 are opened on both sides of the sixth inner groove 19. The first spring 21 is installed inside the seventh inner groove 23, and both ends of the demolding rod 15 are installed above the first spring 21. The top end of the fixing rod 20 passes through the fourth inner groove 16, and the top end of the fourth inner groove 16 corresponds to the lower surface of the fifth inner groove 17. The sixth inner groove 19 forms an elastic structure through the contact of the lower surface of the first spring 21 with both ends of the fixing rod 20, and the lower end of the fixing rod 20 is designed to be inclined.

[0033] When the demolding rod 15 retracts inwards, the top of the demolding rod 15 touches the lower end of the fixed rod 20. Since the lower end of the fixed rod 20 is designed to be inclined, the fixed rod 20 slides upwards along the sixth inner groove 19 and passes through the fourth inner groove 16. At the same time, both sides of the fixed rod 20 press the first spring 21 installed in the seventh inner groove 23. When the first forming inner groove 11 and the second forming inner groove 18 completely coincide, the first mold clamping part 6 and the second mold clamping part 27 also completely coincide. The fourth inner groove 16 and the fifth inner groove 17 are correspondingly arranged. Therefore, after the fixed rod 20 reaches the outlet of the fourth inner groove 16, it will continue to enter the fifth inner groove 17 to complete the effect of secondary fixation. After the production is completed, the second spring 22 ejects the demolding rod 15 along the first inner groove 28 to complete the automatic demolding function.
