Description

Technical Field

[0001] This utility model relates to the field of rubber compound processing technology, specifically to a four-cylinder injection system structure. Background Technology

[0002] Rubber, a material with excellent properties such as high elasticity, insulation, oil resistance, and high temperature resistance, is widely used in many industrial fields such as automobile manufacturing, aerospace, electronics, and construction. Injection molding machines are one of the most commonly used and important pieces of equipment in rubber compound processing. They can rapidly inject rubber compounds into mold cavities under high temperature and pressure, achieving efficient and precise molding of rubber products.

[0003] A prominent issue in the structural design of commonly available rubber injection molding machines is their high proportion of vertical space. This is primarily due to the vertical arrangement of several key components, such as the barrel, injection unit, and mold clamping mechanism. The barrel, responsible for heating and melting the rubber compound, has a length and diameter that determine its heating and conveying capacity. Therefore, the barrel, along with the power system, results in a relatively high overall height. This tall injection molding machine occupies a significant amount of vertical space within the factory, thus reducing the usable available space. Utility Model Content

[0004] The purpose of this invention is to provide a four-cylinder injection system structure to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a four-cylinder injection system structure, including an injection base, with injection cylinders perpendicularly inserted at the four corners of the injection base, a base fixed between the bottom walls of the four injection cylinders, the telescopic ends of the four injection cylinders distributed upwards and fixedly connected to a top seat, and vertically distributed lifting cylinders fixedly installed on the two opposite side walls of the injection base, with the telescopic ends of the lifting cylinders fixedly connected to the base; A pressure rod is fixed to the bottom wall of the top seat. A pressure tank is installed at the center of the injection seat between the four injection cylinders. The bottom end of the pressure rod is inserted into the upper opening of the pressure tank. A hollow docking seat is connected to the bottom opening of the pressure tank. An injection pipe is connected to the bottom opening of the hollow docking seat, and an injection nozzle is installed at the bottom end of the injection pipe. The inner diameter of the pressure tank is used to store the rubber material to be injected, and a heating module is embedded in the inner wall of the pressure tank to soften the rubber material. The pressure rod presses down along the inside of the pressure tank, which can force the softened rubber material out from the nozzle at the bottom of the injection tank.

[0006] In a further embodiment, guide sleeves extend from all four corners of the injection base, and guide posts are slidably inserted into the guide sleeves. The bottom end of the guide post is fixedly connected to the corner of the upper surface of the base.

[0007] In a further embodiment, a feeding component is also included, which includes a feeding tube and a feeding screw that is rotatably embedded in the feeding tube. The side wall of the hollow docking seat is provided with a receiving port connected to one end of the feeding tube, and a transmission seat is fixedly connected to the other end. A motor is fixedly installed at the end of the transmission seat facing away from the feeding tube. The output end of the motor rotates through the transmission seat and is fixedly connected to the feeding screw. The bottom wall of the feeding pipe near the transmission seat has a feeding port.

[0008] In a further embodiment, a tie rod is connected between the top wall of the transmission seat and the side wall of the injection seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model relates to a four-cylinder injection system structure. The injection system structure changes the traditional layout through a unique four-cylinder action design. The four injection cylinders are vertically inserted at the four corners of the injection base, forming a stable structure with the base and top seat. At the same time, the lifting cylinder is used to realize the lifting action of the components, avoiding excessive stacking of components in the vertical direction. This design effectively reduces the overall height of the equipment, greatly reduces the vertical space occupied by the equipment in the factory, improves the utilization rate of the factory space, and reduces the factory construction cost.

[0012] 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.

[0013] In this embodiment, existing rubber injection molding machines suffer from excessive height due to the vertical arrangement of key components such as the barrel and injection device, resulting in excessive vertical space occupation, reduced space utilization, and increased construction costs. Therefore, this embodiment provides a four-cylinder injection system structure, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a shooting base 3, with injection cylinders 12 vertically inserted at each of the four corners of the shooting base 3. A base 4 is fixed between the bottom walls of the four injection cylinders 12. The telescopic ends of the four injection cylinders 12 are distributed upwards and are fixedly connected to a top seat 1. Vertically distributed lifting cylinders 5 are fixedly installed on the two opposite side walls of the shooting base 3. The telescopic ends of the lifting cylinders 5 are fixedly connected to the base 4.

[0014] like Figure 4 As shown, a pressure rod 16 is fixed to the bottom wall of the top seat 1, and a pressure tank 15 located between the four injection cylinders 12 is installed at the center of the injection seat 3. The bottom end of the pressure rod 16 is inserted into the upper opening of the pressure tank 15. A hollow docking seat 14 is connected to the bottom opening of the pressure tank 15. An injection pipe 6 is connected to the bottom opening of the hollow docking seat 14, and an injection nozzle 7 is installed at the bottom end of the injection pipe 6.

[0015] The injection cylinder 12 provides lifting power for the pressure rod 16 to move up and down within the pressure tank 15. The lifting cylinder 5 is used to adjust the relative height of the entire injection base 3, that is, to ultimately adjust the height of the nozzle 7 at the bottom of the injection tube 6 relative to the mold.

[0016] The inner diameter of the pressure tank 15 is used to store the rubber material to be injected, and a heating module is embedded in the inner wall of the pressure tank 15 to soften the rubber material. The pressure rod 16 presses down along the inside of the pressure tank 15, which can press the softened rubber material out from the nozzle 7 at the bottom of the injection tank.

[0017] Guide sleeves extend from all four corners of the shooting base 3. Guide columns 2 are slidably inserted into the guide sleeves. The bottom end of the guide column 2 is fixedly connected to the corner of the upper end face of the base 4. During the operation of the equipment, the guide sleeves and guide columns 2 play a precise guiding role, ensuring that the shooting base 3 can move smoothly and accurately under the drive of the lifting cylinder 5, avoiding vibration and shaking caused by movement deviation.

[0018] At the same time, such as Figure 3 and Figure 4 As shown, it also includes a feeding component, which includes a feeding pipe 8 and a feeding screw that is rotatably embedded in the feeding pipe 8. The side wall of the hollow docking seat 14 is provided with a receiving port that is connected to one end of the feeding pipe 8, and the other end is fixedly connected to a transmission seat 10. A motor 9 is fixedly installed on the end of the transmission seat 10 that is away from the feeding pipe 8. The output end of the motor 9 rotates through the transmission seat 10 and is fixedly connected to the feeding screw. The bottom wall of the end of the feeding pipe 8 near the transmission seat 10 is provided with a feeding port 13.

[0019] The specific process is as follows: The four injection cylinders 12 are pulled upwards, raising the top seat 1 along with the pressure rod 16, increasing the storage space inside the pressure tank 15. Then, the flat rubber strip to be softened is inserted into the feeding pipe 8 through the inlet 13. The feeding screw, driven by the motor 9, rotates within the feeding pipe, uniformly and continuously conveying the rubber material to the hollow docking seat 14, and then into the pressure tank 15. The heating module (which can be a PCT heating element) embedded in the pressure tank 15 softens the rubber material, giving it good fluidity. The pressure rod 16 presses down along the inside of the pressure tank 15, accurately and quickly extruding the softened rubber material from the nozzle 7, ensuring that the rubber material fully fills the mold cavity, improving the molding quality and consistency of the rubber products, and reducing the defect rate.

[0020] A tie rod 11 connects the top wall of the transmission base 10 to the side wall of the injection base 3. The tie rod 11 connecting the top wall of the transmission base 10 and the side wall of the injection base 3 enhances the structural strength. During equipment operation, the tie rod 11 can distribute and bear some of the stress, reduce the stress concentration between components, and reduce fatigue damage caused by long-term stress on the components.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
