Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a thermoplastic molding device for impregnating materials. Background Technology

[0002] Sizing agents are widely used materials in industrial production, primarily for impregnating various objects to improve their properties or surface characteristics. They typically consist of multiple components, including resin, solvent, and additives. Resin is the main component, forming a robust protective film on the object's surface, enhancing its strength, abrasion resistance, and corrosion resistance. Solvents dissolve the resin, allowing it to be evenly applied to the object's surface. Additives improve the sizing agent's properties, such as increasing its adhesion, flexibility, and weather resistance.

[0003] Thermoplastic molding of impregnating materials is a molding process that combines a thermoplastic resin matrix with a reinforcement to form an impregnating material. The process typically involves first controlling the closing of the moving and fixed molds to create an injection cavity between the moving mold and the reinforcement layer, with the moving mold temperature maintained constant between 50°C and 150°C. Molten thermoplastic resin is then injected into the injection cavity, and the moving mold is controlled to extrude the resin within the cavity, impregnating the reinforcement under high temperature and high pressure conditions. Finally, the material cools and solidifies to form the impregnating material.

[0004] After thermoplastic molding, the injection molded body needs to be removed. However, some existing thermoplastic molding devices cannot automatically eject the thermoplastic body, which seriously affects production efficiency. As a result, the thermoplastic body needs to be manually removed after molding, which not only increases labor costs but also causes product damage due to improper operation, reducing the product qualification rate. At the same time, during the manual removal process, operators face the risk of burns due to proximity to the high-temperature mold, posing a safety hazard to production. Therefore, in order to address the above shortcomings, a thermoplastic molding device for impregnating materials is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a thermoplastic molding device for impregnating materials, which aims to improve the problem that some thermoplastic molding devices in the prior art cannot automatically eject thermoplastic bodies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A thermoplastic molding apparatus for impregnating materials includes a base plate, a plurality of support rods fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the plurality of support rods, a driving assembly disposed on the top of the top plate, a moving mold fixedly connected to the bottom of the driving assembly, two arc-shaped plates fixedly connected to the outside of the moving mold, two fixed rods fixedly connected to the bottom of the top plate, pressure rings slidably connected to the outside of each of the two fixed rods, sliding sleeves fixedly connected to the top of each of the two pressure rings, a spring sleeved on the outside of each of the two fixed rods, a connecting plate fixedly connected to the bottom of the two pressure rings, a top rod fixedly connected to the top of the connecting plate, a top plate fixedly connected to the top of the top rod, a reset assembly disposed inside the connecting plate, a sealing assembly disposed outside the top plate, and a fixed mold fixedly connected to the top of the base plate.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a cylinder, the bottom of which is mounted on the top of the top plate, and a push rod is fixedly connected to the drive end of the cylinder, the bottom of which is fixedly connected to the top of the moving mold.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes two slide rods, the two slide rods are slidably connected to the inside of the connecting plate, and springs are sleeved on the outside of each of the two slide rods;

[0012] As a further description of the above technical solution:

[0013] The sealing assembly includes a sealing ring, the inside of which is fixedly connected to the outside of the top plate, and a sealing groove is provided inside the fixed mold, the outside of which is slidably connected to the inside of the sealing groove.

[0014] As a further description of the above technical solution:

[0015] A water inlet pipe is fixedly connected to the front side of the fixed mold, and a lower circulating water pipe is fixedly connected to the rear side of the water inlet pipe. Multiple docking grooves are opened at the top of the lower circulating water pipe. An upper circulating water pipe is fixedly connected to the inside of the moving mold. Multiple docking pipes are fixedly connected to the bottom of the upper circulating water pipe. A water outlet pipe is fixedly connected to the rear side of the upper circulating water pipe. An injection molding pipe is fixedly connected to the front side of the moving mold.

[0016] As a further description of the above technical solution:

[0017] The pressure ring is externally slidably connected to the inside of the base plate, and the fixed rod is externally slidably connected to the inside of the arc-shaped plate;

[0018] As a further description of the above technical solution:

[0019] The connecting plate is internally slidably connected to the outside of the fixed rod, the lower circulating water pipe is externally fixedly connected to the inside of the fixed mold, and the connecting pipe is externally slidably connected to the inside of the docking groove.

[0020] As a further description of the above technical solution:

[0021] One end of the second spring is fixedly connected to the bottom of the base plate, and the other end of the second spring is fixedly connected to the top of the connecting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the cylinder is started, the push rod drives the moving mold to move downward. During this process, the arc plate slides along the fixed rod to ensure the precise movement of the moving mold. At the same time, the sliding sleeve and the pressure ring descend accordingly. The pressure ring compresses the first spring and the connecting plate stretches the second spring. The elastic potential energy stored in the two springs buffers the impact force of mold closing, protecting the mold and equipment. After the thermoplastic material is formed, the cylinder drives the moving mold to rise. The first spring and the second spring release energy, pushing the pressure ring and the connecting plate to move upward. The connecting plate drives the ejector rod, and the ejector rod pushes the top plate, realizing the automatic ejection of the injection molded body from the fixed mold, which greatly improves the demolding efficiency and simplifies the operation process.

[0024] 2. In this utility model, after the thermoplastic product is molded, the water inlet pipe on the front side of the fixed mold introduces external cooling water into the lower circulating water pipe. Due to its square design, the lower circulating water pipe has an increased contact area with the fixed mold, which can fully absorb the heat of the fixed mold and the molded product. When the mold is closed, the top docking groove of the lower circulating water pipe is precisely connected with the bottom docking pipe of the upper circulating water pipe inside the moving mold. The cooling water enters the upper circulating water pipe through this. The square design of the upper circulating water pipe also increases the contact area with the moving mold, cooling the moving mold. Finally, the heated cooling water is discharged from the outlet pipe. The lower circulating water pipe and the upper circulating water pipe work together to cool the fixed mold and the moving mold at the same time, which greatly shortens the cooling time of the thermoplastic product and effectively improves the processing efficiency of the entire thermoplastic molding device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a thermoplastic molding device for impregnating materials, comprising a base plate 1, which serves as the basic support structure for the entire thermoplastic molding device. Multiple support rods 2 are fixedly connected to the top of the base plate 1, and a top plate 3 is fixedly connected to the top of the support rods 2. The support rods 2 primarily support the top plate 3. A driving assembly is provided on the top of the top plate 3, and a moving mold 6 is fixedly connected to the bottom of the driving assembly. Two arc-shaped plates 7 are fixedly connected to the outside of the moving mold 6. The arc-shaped plates 7 allow the moving mold 6 to slide stably along a fixed rod 8 during its up-and-down movement, serving as a guide and limiting mechanism. Two fixed rods 8 are fixedly connected to the bottom of the top plate 3. The outside of the fixed rods 8 is slidably connected to the inside of the arc plate 7. The fixed rods 8 provide guidance for the up and down movement of the moving mold 6. Pressure rings 10 are slidably connected to the outside of both fixed rods 8. When the moving mold 6 moves downward, the sliding sleeve 9 slides downward with the pressure ring 10. The outside of the pressure ring 10 is slidably connected to the inside of the bottom plate 1. The top of both pressure rings 10 is fixedly connected to the sliding sleeve 9. When the moving mold 6 moves downward, the pressure ring 10 slides downward with the moving mold 6. During the sliding process inside the bottom plate 1, the pressure ring 10 plays the role of transmitting force.

[0034] Springs 11 are fitted around the outside of both fixed rods 8. When the moving mold 6 moves downward to close the mold, the pressure ring 10 presses the springs 11 downward, causing them to compress and deform, storing elastic potential energy. When the moving mold 6 moves upward to demold, the springs 11 release their elastic potential energy, pushing the pressure ring 10 upward to assist in demolding the moving mold 6. At the same time, they can buffer the impact force when the moving mold 6 moves downward, improving the stability of the demolding process. Connecting plates 12 are fixedly connected to the bottom of the two pressure rings 10. The interior of the connecting plates 12 is slidably connected to the outside of the fixed rods 8. During the up-and-down movement of the moving mold 6, the connecting plates 12 move together with the pressure rings 10. A push rod 13 is fixedly connected to the top of the connecting plates 12. A top plate 14 is fixedly connected to the top of the push rod 13. The top plate 14 moves under the drive of the push rod 13. When the mold closes, the top plate 14 slides into the interior of the fixed mold 19, without affecting the injection and molding of the thermoplastic material. During demolding, the top plate 14 moves downward under the push of the ejector rod 13, ejecting the molded thermoplastic body from the fixed mold 19, thus completing the demolding operation. The connecting plate 12 is equipped with a reset component inside, and the top plate 14 is equipped with a sealing component outside. The fixed mold 19 is fixedly connected to the top of the bottom plate 1. During the thermoplastic molding process, the moving mold 6 moves downward and closes with the fixed mold 19 to form a closed cavity. After the thermoplastic material is injected into the cavity, it is molded under the combined action of the moving mold 6 and the fixed mold 19.

[0035] Reference Figures 2 to 4 The drive assembly includes a cylinder 4, the bottom of which is mounted on the top of the top plate 3. The cylinder 4 is the power source of the drive assembly. A push rod 5 is fixedly connected to the drive end of the cylinder 4. The bottom of the push rod 5 is fixedly connected to the top of the moving mold 6. Under the drive of the cylinder 4, the push rod 5 drives the moving mold 6 to move up and down. The reset assembly includes two slide rods 15. The two slide rods 15 are slidably connected to the inside of the connecting plate 12. A second spring 16 is sleeved on the outside of each slide rod 15. The slide rods 15 provide support for the second spring 16. One end of the second spring 16 is fixedly connected to the bottom of the base plate 1, and the other end of the second spring 16 is fixedly connected to the top of the connecting plate 12. When the moving mold 6 moves downward to close the mold, the connecting plate 12 moves downward, and the second spring 16 is stretched, storing elastic potential energy. When the moving mold 6 moves upward to demold, the second spring 16 releases its elastic potential energy, assisting the connecting plate 12 to move upward, further improving the stability and reliability of the demolding process. The sealing assembly includes a sealing ring 17, which is internally fixedly connected to the outside of the top plate 14. A sealing groove 18 is provided inside the fixed mold 19, and the outside of the sealing ring 17 is slidably connected to the inside of the sealing groove 18. When the moving mold 6 and the fixed mold 19 are closed, the sealing ring 17 slides into the sealing groove 18 inside the fixed mold 19 along with the top plate 14. The sealing ring 17 fits tightly against the inner wall of the sealing groove 18, forming a good sealing effect, preventing the thermoplastic material from leaking from the connection between the moving mold 6 and the fixed mold 19 during the injection process, and ensuring the normal progress of the thermoplastic molding process.

[0036] Reference Figure 2 , Figure 4 and Figure 5 A water inlet pipe 20 is fixedly connected to the front side of the fixed mold 19, and a lower circulating water pipe 21 is fixedly connected to the rear side of the water inlet pipe 20. After the thermoplastic product is molded, it needs to be cooled. The external cooling water supply system delivers cooling water to the lower circulating water pipe 21 through the water inlet pipe 20. The lower circulating water pipe 21 is externally fixedly connected to the inside of the fixed mold 19. The lower circulating water pipe 21 is designed in a square shape. This square design can maximize the contact area with the fixed mold 19 and improve the cooling efficiency. Multiple docking grooves 22 are opened on the top of the lower circulating water pipe 21. An upper circulating water pipe 23 is fixedly connected to the inside of the moving mold 6. During the process, the upper circulating water pipe 23 receives cooling water from the lower circulating water pipe 21. Multiple connecting pipes 24 are fixedly connected to the bottom of the upper circulating water pipe 23. The external part of the connecting pipe 24 is slidably connected to the inside of the mating groove 22. The connecting pipe 24 can be accurately inserted into the mating groove 22 when the mold is closed. The rear side of the upper circulating water pipe 23 is fixedly connected to the outlet pipe 25. The cooling water that has been cooled and heated by the upper circulating water pipe 23 is discharged through the outlet pipe 25. The front side of the moving mold 6 is fixedly connected to the injection pipe 26. The injection pipe 26 ensures that the thermoplastic material can be injected into the cavity formed by the moving mold 6 and the fixed mold 19 at a suitable pressure and flow rate.

[0037] Working principle: When using this thermoplastic molding device for impregnating materials, the cylinder 4 is first activated to drive the push rod 5 to move, which in turn drives the moving mold 6 to move downward. At this time, the arc plate 7 slides outside the fixed rod 8, and the sliding sleeve 9 and the pressure ring 10 move downward. As the moving mold 6 moves downward, the pressure ring 10 slides inside the base plate 1 and the spring 11 is compressed. At this time, the connecting plate 12 moves downward, which in turn stretches the spring 16. At this time, the elastic force of the spring 11 and the spring 16 can not only buffer the impact during mold closing, but also help the stability of subsequent demolding. At this time, the ejector rod 13 and the ejector plate 14 move downward. When the moving mold 6 and the fixed mold 19 complete the mold closing, the ejector plate 14 slides into the interior of the fixed mold 19, the sealing ring 17 slides into the interior of the sealing groove 18, and the connecting pipe 24 connects to the interior of the docking groove 22, completing the mold closing and forming a sealed space.

[0038] Thermoplastic material can then be injected into the interior of the moving mold 6 and the fixed mold 19 through the injection tube 26. After molding, cooling water can be injected through the water inlet pipe 20. The cooling water flows inside the lower circulating water pipe 21 and is then transported to the interior of the upper circulating water pipe 23 through the connection of the docking groove 22 and the docking pipe 24. Finally, it is discharged through the water outlet pipe 25. With the square design of the lower circulating water pipe 21 and the upper circulating water pipe 23, the contact area with the moving mold 6 and the fixed mold 19 can be maximized, thereby cooling the moving mold 6 and the fixed mold 19 at the same time, which greatly improves the cooling efficiency. Then, the drive cylinder 4 drives the moving mold 6 to move upward, which in turn drives the connecting plate 12 to move upward, which in turn causes the top plate 14 to move downward, thereby realizing the ejection of the thermoplastic body, which greatly improves the processing efficiency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
