Description

Technical Field

[0001] The invention relates to the technical field of injection molding devices, in particular to a molding device for producing rubber gaskets. Background Art

[0002] As an industrial component widely used in mechanical seals, shock absorption and buffering, rubber gaskets have always been the focus of industry attention in terms of production efficiency and product quality. Traditional rubber gasket production and molding devices mainly rely on a single mold for injection molding. The production process generally includes: heating and plasticizing the rubber raw materials through a plasticizing cylinder, using the stirring and shearing action of the plasticizing screw to make the rubber material reach the optimal fluidity state, and then filling the rubber material into the mold cavity of the clamping mold through high-pressure injection. After the rubber material cools and solidifies, it forms a rubber gasket. However, this traditional production method has a significant efficiency bottleneck.

[0003] Specifically, after the traditional device completes the injection of the rubber compound, it needs to wait for the mold to cool naturally until the rubber gasket is formed and has sufficient demolding strength. In order to shorten this waiting time, some devices have introduced mold cooling measures, such as accelerating mold cooling through a circulating water or air cooling system, but they are limited by the continuous operation mode of a single mold, and the injection, cooling and demolding processes still need to be carried out in sequence and cannot be operated in parallel. This means that after one injection molding operation is completed, it is necessary to wait for the mold to be completely cooled and the rubber gasket to be demolded before the next injection molding can be carried out, resulting in an uncompacted production rhythm and low equipment utilization.

[0004] In addition, although increasing the number of injection molding devices can increase the total output to a certain extent, this not only increases the equipment investment cost, but also occupies more production space, and does not fundamentally solve the efficiency problem under the single mold production mode. Therefore, how to further shorten the time interval between injection molding and cooling demoulding by optimizing the device design without increasing the number of equipment and improve the overall work efficiency has become a technical problem that needs to be solved in this field. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a molding device for producing rubber gaskets.

[0006] The technical solution is as follows: A forming device for producing rubber gaskets includes a frame. On one side of the top of the frame, a slidable injection unit is arranged along the length direction. On the other side of the top of the frame, a rotating seat is arranged along the width direction. The injection end of the injection unit faces the rotating seat. Both axial ends of the rotating seat are rotatably connected to the frame through hollow rotating shafts. A plurality of sets of linear modules one are installed in a circumferential annular array on the rotating seat. The fixed ends of each set of linear modules one away from the rotating seat are all fixedly connected together to form a fixed template. The output ends of each set of linear modules one are all fixedly connected together to form a movable template. The opposite sides of the fixed template and the movable template can be closed to form a cavity for injection molding of multiple rubber gaskets. Both the movable template and the fixed template have flow channels for passing cold air. On the side of the fixed template facing away from the movable template, there is an injection hole. The two ends of the flow channel of the fixed template are respectively connected to the two rotating shafts through connecting pipes. The two ends of the flow channel of the movable template are respectively connected to the connecting pipes at both ends of the corresponding fixed template through telescopic hoses. Electric control valves are arranged at the connection nodes between the rotating shaft on one side of the frame and each connecting pipe. A demolding assembly for demolding the formed rubber gaskets is arranged on the fixed template.

[0007] Further, a sliding plate is slidably connected to one side of the frame along the length direction. The injection unit is installed on the top of the sliding plate. A telescopic driving member one is installed below the sliding plate of the frame. The bottom of the sliding plate is fixedly connected to the output end of the telescopic driving member one.

[0008] Further, the demolding assembly includes ejector rods and elastic members. A plurality of pairs of ejector rods are slidably connected to the side of the movable template facing away from the fixed template. Each pair of ejector rods corresponds to one cavity. An elastic member is connected between the outer end of the ejector rod and the side of the movable template facing away from the fixed template.

[0009] Further, a worm gear is fixedly connected to the rotating shaft on one side of the frame. A motor is installed on the top of the frame on the same side as the worm gear. The output shaft of the motor is fixedly connected to a worm. The worm gear and the worm are meshed and driven.

[0010] Further, it also includes a spraying assembly for spraying a demolding agent on the inner surfaces of the cavities of the fixed template and the movable template. The spraying assembly includes two storage boxes. On the opposite sides of the two storage boxes, spraying panels are slidably connected. A plurality of spraying holes are opened on the spraying panels. Elastic sponge pads are placed in the storage boxes. The sponge pads are used to store the demolding agent and release the demolding agent when being squeezed by the spraying panels. The spraying assembly also includes an actuating mechanism for driving the storage boxes to perform the demolding agent spraying action.

[0011] Further, the actuating mechanism includes a linear module two, a telescopic driving member two, and a telescopic driving member three. A fixed frame is fixedly connected to one side of the top of the frame. A linear module two is installed on the fixed frame. The output end of the linear module two is fixedly connected to a fixing plate one. The telescopic driving member two is installed on the fixing plate one. The output end of the telescopic driving member two is fixedly connected to a fixing plate two. Two telescopic driving members three are respectively installed on both sides of the fixing plate two. The opposite sides of the two storage boxes are respectively fixedly connected to the output ends of the two telescopic driving members three.

[0012] Furthermore, a storage box is fixedly connected to the top of the fixing frame. The storage box is used to store the mold release agent, and the storage box is connected to the two storage boxes through a telescopic Y-shaped pipe.

[0013] Furthermore, a semi-circular support plate is fixedly connected to the fixing frame. The support plate is used to support the Y-shaped pipe. A limit ring is provided on the fixed end of the telescopic driving member II, and the Y-shaped pipe passes through the limit ring.

[0014] The present invention has the following advantages: 1. The present invention adopts the design of a rotating seat and multiple sets of mold components, so that multiple processes such as spraying mold release agent, injecting rubber material, passing cold air for cooling, and demolding of multiple mold components can be carried out simultaneously on a single injection molding device. Through the rotation of the rotating seat, each mold component can sequentially enter the injection station, the cooling station, and the demolding station, realizing the parallel processing of processes, greatly shortening the production cycle, and improving the equipment utilization rate and production efficiency.

[0015] 2. Flow channels for passing cold air are provided in both the fixed template and the movable template. By introducing cold air into the flow channels through an external air supply device, the heat of the mold can be quickly removed, and the cooling and forming of the rubber gasket can be accelerated. At the same time, through the precise control of the electric control valve, it can be ensured that cold air is only introduced into the mold components in the cooling station, avoiding unnecessary energy waste and improving the cooling efficiency.

[0016] 3. The present device is provided with a spraying component for spraying the mold release agent on the cavity. Through the cooperation of the linear module and the telescopic driving member, the spraying operation of the mold release agent can be automatically completed. During the process of the spraying panel squeezing the sponge pad, the mold release agent is evenly sprayed on the inner surface of the cavity, effectively preventing the adhesion and damage of the rubber gasket during the demolding process and improving the product quality.

Detailed implementation manners

[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] Please refer to Figures 1-8, a molding device for producing rubber gaskets, including a frame 1. On one side of the top of the frame 1 along the length direction, a slidable injection unit 2 is arranged. On the other side of the top of the frame 1 along the width direction, a rotating seat 3 is arranged. The injection end of the injection unit 2 faces the rotating seat 3. Both axial ends of the rotating seat 3 are rotatably connected to the frame 1 through hollow rotating shafts 4. Four groups of linear modules one 5 are installed on the rotating seat 3 in a circumferential annular array. The fixed ends of each group of linear modules one 5 away from the rotating seat 3 are jointly fixedly connected to a fixed template 6. The output ends of each group of linear modules one 5 are jointly fixedly connected to a movable template 7. To ensure the installation stability of the fixed template 6 and the movable template 7, in this embodiment, a guiding column is fixedly connected to the rotating seat 3 parallel to the linear module one 5. The opposite sides of the fixed template 6 and the movable template 7 can be closed to form a cavity for injecting and molding multiple rubber gaskets. In this embodiment, the main position of the cavity is on the side of the movable template 7 close to the fixed template 6. The fixed template 6 has injection holes corresponding to the cavity. Both the movable template 7 and the fixed template 6 have channels for passing cold air. The side of the fixed template 6 facing away from the movable template 7 has an injection hole. The two ends of the channel of the fixed template 6 are respectively connected to the two rotating shafts 4 through a connecting pipe 801. The two ends of the channel of the movable template 7 are respectively connected to the connecting pipes 801 at both ends of the corresponding fixed template 6 through a telescopic hose 802. Electric control valves (not shown in the drawings) are arranged at the connection nodes of the rotating shaft 4 on one side of the frame 1 and each connecting pipe 801. The electric control valves are used to control the on-off of the cold air. A demolding assembly is arranged on the fixed template 6 for demolding the molded rubber gaskets.

[0028] To drive the injection unit 2 to move along the length direction of the frame 1, a sliding plate 9 is slidably connected to one side of the frame 1 along the length direction. The injection unit 2 is installed on the top of the sliding plate 9. A telescopic driving member one 10 is installed below the sliding plate 9 of the frame 1. The bottom of the sliding plate 9 is fixedly connected to the output end of the telescopic driving member one 10.

[0029] The demolding assembly includes ejector rods 11 and elastic members 12. On the side of the movable template 7 facing away from the fixed template 6, multiple pairs of ejector rods 11 are slidably connected. Each pair of ejector rods 11 corresponds to a cavity. An elastic member 12 is connected between the outer end of the ejector rod 11 and the side of the movable template 7 facing away from the fixed template 6. The elastic member 12 is used to provide a reset force for the ejector rod 11 after demolding.

[0030] To drive the rotation of the rotating shaft 4, a worm gear 14 is fixedly connected to the rotating shaft 4 on one side of the frame 1. A motor 13 is installed on the top of the frame 1 on the same side as the worm gear 14. The output shaft of the motor 13 is fixedly connected to a worm 15. The worm gear 14 and the worm 15 are engaged and driven.

[0031] In order to improve the demolding effect, in the present embodiment, a molding device for producing rubber gaskets also includes a spraying assembly for spraying a demolding agent on the inner surface of the cavity of the fixed mold plate 6 and the movable mold plate 7, the spraying assembly includes two storage boxes 16, and the two storage boxes 16 are slidably connected to the opposite sides with a spraying panel 17, and the spraying panel 17 is provided with a plurality of spraying holes. An elastic sponge pad 18 is placed in the storage box 16, and the sponge pad 18 is used to store the demolding agent and release the demolding agent when squeezed by the spraying panel 17, and the spraying assembly also includes an actuator for driving the storage box 16 to perform the demolding agent spraying action.

[0032] The actuator includes a linear module 19, a telescopic drive member 20 and a telescopic drive member 3 21. A fixing frame 22 is fixedly connected to one side of the top of the frame 1, and a linear module 19 is installed on the fixing frame 22. The output end of the linear module 19 is fixedly connected to a fixing plate 23. The telescopic drive member 20 is installed on the fixing plate 23. The output end of the telescopic drive member 20 is fixedly connected to a fixing plate 24. Two telescopic drive members 3 21 are respectively installed on both sides of the fixing plate 24. The two storage boxes 16 are respectively fixed to the two telescopic drive members 3 21 on the opposite sides. At the output end, in order to prevent the fixed frame 22 and the actuator thereon from affecting the movement trajectory of the connecting components on the rotating seat 3, the length of the fixed frame 22 along the width direction of the frame 1 is greater than the axial length of the rotating seat 3, and the height of the linear module 2 19 on the fixed frame 22 is greater than the maximum height that the linear module 1 5 on the rotating seat 3 can reach, and the installation height of the telescopic driving member 20 on the fixed plate 1 23 is less than the maximum height that the bottom surface of the fixed template 6 on the rotating seat 3 can reach, so that the two storage boxes 16 can smoothly enter the bottom of the cavity of the fixed template 6.

[0033] In order to ensure the continuous supply of the release agent in the storage box 16 , a storage box 25 is fixedly connected to the top of the fixed frame 22 . The storage box 25 is used to store the release agent. The storage box 25 is connected to the two storage boxes 16 through a retractable Y-shaped tube 26 .

[0034] In order to prevent the Y-shaped tube 26 from affecting the movement trajectory of the connecting components on the rotating seat 3, a half-moon-shaped support plate 27 is fixedly connected to the fixed frame 22, and the support plate 27 can open the Y-shaped tube 26. A limiting ring 28 is provided on the fixed end of the telescopic driving member 20, and the Y-shaped tube 26 passes through the limiting ring 28 to prevent the Y-shaped tube 26 from swinging at will.

[0035] In this embodiment, the stationary template 6 and the moving template 7 on the same side of the rotating seat 3 are referred to as a set of mold components, and are sequentially named the first group, the second group, the third group, and the fourth group of mold components in the rotation direction of the rotating seat 3. Initially, the first mold component is at the top of the rotating seat 3, and the first fixing plate 23 is located outside one axial end of the linear module two 19 relative to the rotating seat 3 to prevent the actuating mechanism and the storage box 16 on the first fixing plate 23 from affecting the movement trajectories of the mold components on the rotating seat 3. The collection box is placed below the rotating seat 3 in the frame 1 and on the side far from the injection unit 2. The air outlet end of the external air supply device is connected to the rotating shaft 4 with an electric control valve, and the air inlet end of the external air supply device is connected to another rotating shaft 4. All electric control valves are in the closed state, and all the moving templates 7 are kept in the closed state with the stationary templates 6 under the drive of the linear module one 5.

[0036] During use, first, the movable template 7 is driven by the first linear module 5 corresponding to the first mold assembly to move away from the fixed template 6 by an appropriate distance. The fixed plate 1 and the material storage box 16 thereon are driven by the second linear module 19 to move along the width direction of the frame 1 and reach the position corresponding to the first cavity of the first mold assembly where they meet vertically in the moving direction. Subsequently, the second telescopic driving member 20 drives the fixed plate 24 to move closer to the cavity of the first mold assembly until the two material storage boxes 16 are in the same vertical straight line as the cavity of the first mold assembly. Then, the two telescopic driving members 3 21 respectively drive the two material storage boxes 16 to move away from each other until the spraying panels 17 of the two material storage boxes 16 respectively abut against the inner surfaces of the cavities of the fixed template 6 and the movable template 7. During this process, the spraying panel 17 slides in the direction of approaching the sponge pad 18 relative to the box body of the material storage box 16, and the spraying panel 17 presses the sponge pad 18, so that the mold release agent in the sponge pad 18 is sprayed out and passes through the spraying holes of the spraying panel 17 to contact the corresponding inner surface of the cavity. Then, the two telescopic driving members 3 21 respectively drive the two material storage boxes 16 to move back to their original positions. During this process, the spraying panel 17 will reset under the elastic action of the sponge pad 18. At the same time, the material storage tank 25 can replenish the mold release agent to the material storage box 16 through the Y-shaped pipe 26. Then, the fixed plate 1 and the material storage box 16 thereon are driven by the second linear module 19 to continue to move along the width direction of the frame 1 to sequentially complete the spraying operation of the mold release agent for the remaining cavities of the first mold assembly. Finally, the second telescopic driving member 20 drives the fixed plate 24 to move away from the cavity of the first mold assembly and reset, and the fixed plate 1 is driven by the second linear module 19 to continue to move along the width direction of the frame 1 until the fixed plate 1 reaches the outer side of the other axial end of the second linear module 19 relative to the rotating seat 3. When the next group of mold assemblies needs to be sprayed with the mold release agent, only the fixed plate 1 needs to be driven by the second linear module 19 to move in the reverse direction along the width direction of the frame 1. In this way, by repeating the cycle, the spraying operation of the mold release agent can be sequentially performed on different groups of mold assemblies.

[0037] After the first mold assembly completes the spraying of the mold release agent, the movable template 7 is driven by the linear module 5 corresponding to the first mold assembly to move closer to the fixed template 6 until they are re-closed to form a cavity for injection molding. The worm 15 is driven to rotate by the motor 13. Under the meshing drive of the worm 15 and the worm gear 14, the rotating shaft 4 is driven to rotate, and then the rotating seat 3 and the first group of mold assemblies on its top rotate to the side close to the injection unit 2. Moreover, the injection holes on the fixed template 6 of the first group of mold assemblies are aligned with the injection end of the injection unit 2. At this time, the position where the first group of mold assemblies is located is the injection station. Subsequently, the sliding plate 9 and the injection unit 2 thereon are driven to move towards the fixed template 6 by the first telescopic driving member 10 until the injection end of the injection unit 2 is aligned with the injection hole of the fixed template 6. Then, rubber raw materials are injected into the injection cylinder in the injection molding unit, and the molten rubber raw materials are injected into the multiple cavities formed by the closing of the fixed template 6 and the movable template 7 through the injection unit 2. Then, the electromagnetic valve corresponding to the connecting pipe 801 of the fixed template 6 of the first group of mold assemblies is opened, and cold air is introduced from the rotating shaft 4 with the electromagnetic valve through an external air supply device. The cold air enters one end of the flow channels in the fixed template 6 and the movable template 7 respectively after passing through the electromagnetic valve, the corresponding connecting pipe 801 and the telescopic hose 802, and finally is discharged from another rotating shaft 4 after passing through the other end of the flow channels, the corresponding connecting pipe 801 and the telescopic hose 802. During this process, the continuous flow of the cold air cools the fixed template 6 and the movable template 7 of the first group of mold assemblies, thereby quickly cooling the rubber gaskets formed in the cavities of the first group of mold assemblies.

[0038] After the first group of mold assemblies is cooled for a period of time, the sliding plate 9 and the injection unit 2 thereon are driven by the first telescopic driving member 10 to move in the reverse direction to reset. Then, the rotating seat 3 is driven to rotate by the motor 13, so that the first group of mold assemblies rotates to the lower part relative to the rotating seat 3. At this time, the second group of mold assemblies of the rotating seat 3 comes to the injection station to prepare for the injection of rubber raw materials. During this process, the first group of mold assemblies continues to be cooled by ventilation. After the second group of mold assemblies repeats the above injection operation of the rubber raw materials, the electromagnetic valve corresponding to the connecting pipe 801 of the fixed template 6 of the second group of mold assemblies is opened, so that the rubber gaskets formed in the cavities of the second group of mold assemblies can also be cooled by passing cold air.

[0039] When the rubber gasket of the first group of mold assemblies has been cooled, the motor 13 is used to drive the rotating seat 3 to rotate again, so that the first group of mold assemblies rotate to the side of the rotating seat 3 away from the injection unit 2. At this time, the position of the first group of mold assemblies is the demolding station. At this time, the electric control valve of the connecting pipe 801 corresponding to the fixed mold plate 6 of the first group of mold assemblies is closed to stop the cooling air supply to the first group of mold assemblies. The electric control valve corresponding to the second group of mold units remains open for continuous ventilation. Then, the linear module 5 corresponding to the first group of mold assemblies drives the movable mold plate 7 to move away from the fixed mold plate 6 until the ejector pin 11 on the movable mold plate 7 conflicts with the rotating seat 3. During the continuous movement of the movable mold plate 7, the ejector pin 11 moves closer to the fixed mold plate 6 relative to the movable mold seat, so that the ejector pin 11 can push the rubber gasket in the cavity to demold. During this process, the elastic member 12 will be compressed to provide a reset force for the subsequent reset of the ejector pin 11.

[0040] By analogy, in a reciprocating cycle, each mold assembly can complete the entire process of spraying release agent, injecting rubber, cooling with cold air and demoulding, which is the same as the first mold assembly, thereby realizing the automated production operation of the rubber gasket.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
