Description

Technical Field

[0001] This utility model relates to the field of liquid silicone injection molding technology, and in particular to a vertical liquid silicone injection molding device. Background Technology

[0002] In the field of liquid silicone injection molding, traditional vertical injection molding equipment often suffers from uneven raw material mixing and insufficient temperature control precision, resulting in poor quality stability of injection molded products. Existing equipment often has a fixed-depth mixing structure, which is difficult to adapt to the mixing requirements of different raw material quantities. Moreover, shaking is prone to occur during the mixing process, affecting the mixing effect. At the same time, the sealing performance of the raw material conveying link is poor, and liquid silicone leakage occurs frequently, which not only wastes raw materials but also pollutes the production environment and increases cleaning costs. In addition, the automation level of traditional equipment is low, and the feeding, mixing, and conveying links require a lot of manual intervention, resulting in low production efficiency. Furthermore, the loose layout of various components occupies a lot of space, which is not conducive to the efficient use of workshop space. To solve the above problems, it is necessary to develop a vertical liquid silicone injection molding device with a high degree of integration, uniform mixing, reliable sealing, and strong automation. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide a vertical liquid silicone injection molding device that can solve the problems of insufficient mixing, easy solidification, and defective sealing after stirring.

[0005] To solve the above technical problems, this utility model provides a vertical liquid silicone injection molding device, which adopts the following technical solution: It includes a base plate, a first support fixedly connected to the top of the base plate near its center, a second top plate fixedly connected to the top of the first support, a second support fixedly connected to the top of the second top plate, a first mounting plate fixedly connected to the inner wall of the second support near its bottom, a cooling chamber fixedly connected to the upper end of the first mounting plate, a stirring tank inserted inside the cooling chamber, the first top plate fixedly connected to the top of the second support, an electric telescopic rod fixedly connected to the bottom of the first top plate, a double-layer support fixedly connected to the bottom of the electric telescopic rod, a rotating shaft rotatably connected to the center of the bottom of the double-layer support, auger blades fixedly connected to the outer surface of the rotating shaft, an injection molding machine installed at the bottom of the second top plate, and a clamping and anti-seepage structure provided between the first mounting plate and the second top plate.

[0006] The clamping and seepage-proof structure includes a second mounting plate, a semi-circular hoop, and a semi-circular sealing ring.

[0007] Optionally, a control device is provided on the top right side of the base plate, and a feeding machine is provided on the top left side of the base plate. A conveying pipe is provided at the right end of the feeding machine, and the mixing tank is located at the lower end of the conveying pipe on the side away from the feeding machine.

[0008] The above technical solution involves a control device located on the top right side of the base plate, which serves as the control center for the entire device and can regulate the start / stop and conveying speed of the feeder.

[0009] Optionally, the upper end of the double-layer bracket is fixedly connected with a guide rod, and the guide rod is two in number and symmetrically distributed on both sides of the electric telescopic rod.

[0010] The above technical solution ensures the stability of the auger blades during movement by allowing the electric telescopic rod to extend and retract, causing the double-layer support to move up and down.

[0011] Optionally, a large gear is fixedly connected to the top of the rotating shaft, a first drive motor is fixedly connected to the top of the double-layer bracket, a small gear is fixedly connected to the output end of the first drive motor, and the outer surface of the small gear meshes with the large gear.

[0012] Through the above technical solution: after the first drive motor starts, the small gear drives the large gear to rotate, which in turn causes the rotating shaft to rotate. The auger blades on the outer surface of the rotating shaft rotate accordingly, stirring and mixing the liquid silica gel in the mixing tank to ensure that the raw material composition is uniform.

[0013] Optionally, the upper and lower ends of the second mounting plate are fixedly connected to the first mounting plate and the second top plate, respectively.

[0014] Through the above technical solution: the upper and lower ends of the second mounting plate are fixedly connected to the first mounting plate and the second top plate respectively, providing an installation base for clamping other components in the seepage prevention structure.

[0015] Optionally, a second drive motor is fixedly connected to the left side of the second mounting plate, and a positive and negative threaded rod is fixedly connected to the output end of the second drive motor. The outer surface of the positive and negative threaded rod is threadedly connected to the outer side of the semi-circular hoop.

[0016] Through the above technical solution, the two semi-circular hoops will move towards each other along the positive and negative threaded rods until they clamp the output pipe of the mixing tank and the inlet pipe of the injection molding machine, thereby achieving the clamping and fixing of the pipes.

[0017] Optionally, the number of semicircular hoops is two and they are symmetrically distributed, and the inner wall of the semicircular hoops is fixedly connected to the semicircular sealing ring.

[0018] Through the above technical solution: when the semi-circular hoop clamps the output pipe of the mixing tank and the inlet pipe of the injection molding machine, the semi-circular sealing ring fits tightly against the outer wall of the pipe, enhancing the sealing performance of the pipe connection and effectively preventing liquid silicone leakage.

[0019] Optionally, the inner wall of the semi-circular sealing ring is tightly fitted to the output pipe of the mixing tank and the inlet pipe of the injection molding machine, respectively. A first sealing ring is provided at the bottom of the output pipe of the mixing tank, and a second sealing ring is provided at the top of the inlet pipe of the injection molding machine. The first sealing ring and the second sealing ring are tightly fitted together.

[0020] Through the above technical solution: the inner wall of the semi-circular sealing ring is tightly fitted with the output pipe of the mixing tank and the inlet pipe of the injection molding machine, and at the same time, the first sealing ring at the bottom of the output pipe of the mixing tank is tightly fitted with the second sealing ring at the top of the inlet pipe of the injection molding machine, forming a double seal.

[0021] In summary, this utility model has at least one of the following beneficial effects:

[0022] 1. The equipment exhibits excellent homogenization and temperature control capabilities during the raw material processing stage. The rotation of the auger blades within the mixing tank ensures thorough stirring and mixing of the liquid silicone, guaranteeing uniform raw material composition and preventing variations in composition from affecting the performance of subsequent injection-molded products. Simultaneously, the cooling chamber allows for precise temperature control of the liquid silicone within the mixing tank, effectively preventing premature curing due to excessively high temperatures or a decline in injection molding quality due to uneven temperatures. This provides a stable and high-quality raw material foundation for subsequent injection molding processes.

[0023] 2. The design of the clamping and anti-leakage structure effectively solves the leakage problem during the injection molding process. The second drive motor drives the positive and negative threaded rods to rotate, causing the two semi-circular hoops to move towards each other, clamping the output pipe of the mixing tank and the inlet pipe of the injection molding machine. The semi-circular sealing ring on the inner wall of the semi-circular hoop fits tightly against the outer wall of the pipe. At the same time, the first sealing ring at the bottom of the output pipe of the mixing tank and the second sealing ring at the top of the inlet pipe of the injection molding machine squeeze each other to form a double seal, which greatly reduces the risk of liquid silicone leakage. This not only avoids material waste but also ensures the cleanliness and safety of the production environment. Attached Figure Description

[0034] A control device 2 is located on the top right side of the base plate 1, and a feeder 3 is located on the top left side of the base plate 1. A conveying pipe 4 is located at the right end of the feeder 3. The mixing tank 16 is located at the lower end of the conveying pipe 4 on the side away from the feeder 3. A guide rod 8 is fixedly connected to the upper end of the double-layer bracket 15. There are two guide rods 8, which are symmetrically distributed on both sides of the electric telescopic rod 9. A large gear 12 is fixedly connected to the top of the rotating shaft 13. A first drive motor 10 is fixedly connected to the top of the double-layer bracket 15. A small gear 11 is fixedly connected to the output end of the first drive motor 10. The outer surface of the small gear 11 meshes with the large gear 12. The upper and lower ends of the second mounting plate 27 are fixedly connected to the first mounting plate 26 and the second top plate 18, respectively.

[0035] The clamping anti-seepage structure includes a second mounting plate 27, a semi-circular hoop 21, and a semi-circular sealing ring 22.

[0036] A second drive motor 19 is fixedly connected to the left side of the second mounting plate 27. A positive and negative threaded rod 20 is fixedly connected to the output end of the second drive motor 19. The outer surface of the positive and negative threaded rod 20 is threadedly connected to the outer side of the semicircular hoop 21. There are two semicircular hoops 21, which are symmetrically distributed. The inner wall of the semicircular hoop 21 is fixedly connected to the semicircular sealing ring 22. The inner wall of the semicircular sealing ring 22 is tightly fitted to the output pipe of the mixing tank 16 and the inlet pipe of the injection molding machine 25, respectively. A first sealing ring 23 is provided at the bottom of the output pipe of the mixing tank 16, and a second sealing ring 24 is provided at the top of the inlet pipe of the injection molding machine 25. The first sealing ring 23 and the second sealing ring 24 are tightly fitted together.

[0037] Working principle: In the raw material feeding stage, the feeder 3 serves as the raw material supply source, conveying liquid silicone raw material to the mixing tank 16 through the conveying pipe 4. The outlet of the conveying pipe 4 is located at the upper end of the mixing tank 16 to ensure accurate entry of the raw material. The control device 2 can adjust the start and stop of the feeder 3 and the conveying speed. In the mixing and homogenization stage, after the first drive motor 10 starts, the small gear 11 at the output end drives the meshing large gear 12 to rotate, thereby causing the rotating shaft 13 to rotate. The auger blades 14 on the outer surface of the rotating shaft 13 rotate with the shaft, stirring and mixing the liquid silicone in the mixing tank 16 to ensure uniform raw material composition. At the same time, when the electric telescopic rod 9 extends and retracts, it will drive the double-layer support 15 to move up and down, thereby adjusting the depth of the rotating shaft 13 and the auger blades 14 in the mixing tank 16 to adapt to the mixing requirements of different raw material amounts. The guide rods 8 on both sides of the double-layer support 15 slide along the guide holes of the first top plate 7 to ensure the stability of the auger blades 14 when they move.

[0038] During the cooling control stage, the mixing tank 16 is inserted into the cooling chamber 17. The cooling chamber 17 controls the temperature of the liquid silicone in the mixing tank 16 through preset cooling, so as to prevent the liquid silicone from curing prematurely due to excessive temperature or causing a decline in the quality of subsequent injection molding due to uneven temperature.

[0039] During the clamping, sealing, and raw material conveying stage, after the second drive motor 19 starts, it drives the positive and negative threaded rods 20 to rotate. Since the thread directions of the positive and negative threaded rods 20 are symmetrical, the two semi-circular hoops 21 will move towards each other along the positive and negative threaded rods 20 until they clamp the output pipe of the mixing tank 16 and the inlet pipe of the injection molding machine 25. The semi-circular sealing ring 22 on the inner wall of the semi-circular hoop 21 fits tightly against the outer wall of the pipe. At the same time, the first sealing ring 23 at the bottom of the output pipe of the mixing tank 16 and the second sealing ring 24 at the top of the inlet pipe of the injection molding machine 25 squeeze each other to form a double seal to prevent liquid silicone from leaking. After the sealing is completed, the auger blades 14 continue to rotate, and through the spiral pushing action, the liquid silicone in the mixing tank 16 is pressed into the injection molding machine 25 through the output pipe and the inlet pipe.

[0040] In the injection molding stage, the injection molding machine 25 receives the processed liquid silicone and injects it into the mold according to the preset parameters, thus completing the injection molding of the product.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
