Description

A quick-release connection tooling for pipe injection molding equipment Technical Field

[0001] This utility model relates to the field of quick-release connections, and in particular to a quick-release connection tooling for pipe injection molding equipment. Background Technology

[0002] Pipe injection molding equipment is a specialized piece of equipment used to produce plastic pipes. It can mold thermoplastic or thermosetting plastics into various shapes of plastic products through plastic molds. In the plastic manufacturing and processing industry, injection molding machines need to transport raw materials, water, gas, etc. through various pipes.

[0003] Existing pipe connection fixtures typically require bolt tightening with tools, which is time-consuming and inefficient. This causes inconvenience when quick pipe replacement or maintenance is needed, and they are not applicable to various specifications and models of pipe injection molding equipment. They lack versatility and have significant limitations. Furthermore, the quick-release connection fixtures for existing pipe injection molding equipment are fixed in position and cannot be moved or adjusted according to the pipe's location, resulting in poor flexibility. Therefore, providing a connection fixture that can be quickly installed and disassembled is particularly important.

[0004] Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a quick-release connection tooling for pipe injection molding equipment to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-release connection fixture for a pipe injection molding equipment, including a lifting chamber and two arc-shaped plates. A drive motor is installed at the upper end of the lifting chamber. The output shaft of the drive motor passes through the lifting chamber and is equipped with forward and reverse lead screws. A lead screw slide is installed on the forward and reverse lead screws. A connecting groove is provided in the middle of the front wall of the lifting chamber. The front end of the lead screw slide passes through the connecting groove and is equipped with a fixing box.

[0007] As a preferred technical solution of this utility model, two first electric hydraulic cylinders are installed in the middle of the outer side wall of the arc plate. The inner end of each first electric hydraulic cylinder passes through the arc plate and is equipped with an elastic head. The elastic head is made of rubber material. When the four first electric hydraulic cylinders are activated, the first electric hydraulic cylinders drive the elastic head to move inward, thereby squeezing and fixing the upper and lower ends of the pipe, thus fixing pipes of different models.

[0008] As a preferred technical solution of this utility model, two second electric hydraulic cylinders are installed inside the fixed box. The front end of each second electric hydraulic cylinder passes through the fixed box and is equipped with a mounting seat. The mounting seat is connected to the arc plate by fixing bolts. When the second electric hydraulic cylinder is started, the mounting seat moves forward, thereby driving the two arc plates to move back and forth, so as to realize the adjustment of the pipe position.

[0009] As a preferred embodiment of this invention, a base is installed at the lower end of the lifting chamber. Two rollers are provided on each side wall of the base, and a connecting shaft is installed between the rollers. A dual-head motor is installed in the center of the base, and output rods are installed at both ends of the dual-head motor. Six bevel gears are provided at the connection points between the output rods and the connecting shafts. When the dual-head motor is started, it drives the two output rods to rotate, which in turn drives the bevel gears to rotate, thereby driving the two connecting shafts to rotate, which in turn drives the rollers to rotate, thus enabling the device to move and providing convenience and flexibility.

[0010] As a preferred technical solution of this utility model, the arc-shaped plate is made of stainless steel, and a rubber layer is provided inside the stainless steel. The rubber layer is provided with a high-temperature resistant heat insulation coating. The high-temperature resistant heat insulation coating can improve the high-temperature resistance of the inner walls of the two arc-shaped plates and avoid the impact of high temperature on the arc-shaped plates.

[0011] As a preferred technical solution of this utility model, a PLC control panel is installed on the lower part of the left side wall of the lifting chamber. The PLC control panel is electrically connected to the drive motor for convenient control of the operation.

[0012] As a preferred technical solution of this utility model, the lifting chamber is made of aluminum alloy material and formed by hot extrusion process, which results in a lighter weight with a smaller volume and better structural heat dissipation. The aluminum alloy shell formed by hot extrusion process has strong corrosion resistance and good oxidation resistance. It can form an oxide film to prevent metal corrosion in humid air, thereby improving service life.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] 1. In this utility model, starting the drive motor causes the forward and reverse lead screws to rotate via the output shaft, thereby moving the two lead screw slides inward and the two arc-shaped plates inward. Simultaneously, starting the four first electric hydraulic cylinders causes the elastic heads to move inward, compressing and fixing the upper and lower ends of the pipe, thus securing pipes of different models and achieving quick-connection of the pipes. This adapts to the production needs of different pipes and improves the applicability of the tooling. Starting the second electric hydraulic cylinder moves the mounting base forward, thereby causing the two arc-shaped plates to move back and forth, adjusting the pipe position. This replaces bolts for fixing, saving time and effort. It is applicable to various specifications and models of pipe injection molding equipment, possessing strong versatility and not being limited by limitations.

[0015] 2. In this utility model, by starting the dual-head motor, the dual-head motor drives the two output rods to rotate, which in turn drives the bevel gears to rotate, thereby driving the two connecting shafts to rotate, which in turn drives the roller 4 to rotate, thus realizing the movement of the device position, bringing convenience and flexibility.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0025] It should be noted that the drive motor 5, the first electric hydraulic cylinder 7, the second electric hydraulic cylinder 10, and the dual-head motor 21 are all existing technologies and are common knowledge to those skilled in the art, and will not be elaborated upon here.

[0026] Specific implementation examples are given below.

[0027] Referring to 1-6, in this embodiment of the present invention, a quick-release connection fixture for a pipe injection molding equipment includes a lifting chamber 1 and two arc-shaped plates 8. A drive motor 5 is installed at the upper end of the lifting chamber 1. The output shaft of the drive motor 5 passes through the lifting chamber 1 and is equipped with forward and reverse lead screws 16. Lead screw slides 17 are driven and installed on the forward and reverse lead screws 16. A connecting groove 6 is provided in the middle of the front wall of the lifting chamber 1. The front end of the lead screw slide 17 passes through the connecting groove 6 and is equipped with a fixing box 9. When the drive motor 5 is started, the drive motor 5 drives the forward and reverse lead screws 16 to rotate through the output shaft, thereby driving the two lead screw slides 17 to move inward and the two arc-shaped plates 8 to move inward, saving time and effort.

[0028] Two first electric hydraulic cylinders 7 are installed in the middle of the outer wall of the arc-shaped plate 8. The inner end of each first electric hydraulic cylinder 7 passes through the arc-shaped plate 8 and is equipped with an elastic head 15 made of rubber. When the four first electric hydraulic cylinders 7 are activated, they all drive the elastic heads 15 to move inward, compressing and fixing the upper and lower ends of the pipe, thereby fixing pipes of different models. Two second electric hydraulic cylinders 10 are installed inside the fixing box 9. The front end of each second electric hydraulic cylinder 10 passes through the fixing box 9 and is equipped with a mounting base 11. The mounting base 11 is connected to the arc-shaped plate 8 by fixing bolts. Activating the second electric hydraulic cylinder 10 moves the mounting base 11 forward, thereby causing the two arc-shaped plates 8 to move back and forth, thus adjusting the pipe position. A base 3 is installed at the lower end of the lifting chamber 1. Two rollers 4 are provided on each side wall of the base 3, and a connecting shaft 19 is installed between the rollers 4. A double-headed motor 18 is installed in the center of the base 3. Output rods 21 are installed at both ends of the double-headed motor 18. Bevel gears 20 are provided at the connection points between the output rods 21 and the connecting shaft 19. The lifting chamber 1 has six components. The dual-head motor 18 is activated, driving two output rods 21 to rotate, which in turn drives the bevel gear 20, which in turn drives two connecting shafts 19, which in turn drives the rollers 4, enabling the device to move and providing convenience and flexibility. The arc-shaped plate 8 is made of stainless steel 12, with a rubber layer 13 inside. The rubber layer 13 has a high-temperature resistant heat-insulating coating 14 inside, which improves the high-temperature resistance of the inner walls of the two arc-shaped plates 8, preventing high temperatures from affecting them. A PLC control panel 2 is installed on the lower left side wall of the lifting chamber 1. The PLC control panel 2 is electrically connected to the drive motor 5 and the dual-head motor 18 for convenient operation control. The lifting chamber 1 is made of aluminum alloy and formed through a hot extrusion process, resulting in a lighter weight for a smaller volume and better structural heat dissipation. The aluminum alloy shell formed through hot extrusion has strong corrosion resistance and good oxidation resistance, forming an oxide film in humid air to prevent metal corrosion, thus improving its service life.

[0029] Working principle: The device is placed at the location where pipe injection molding is required. The pipe is placed between two arc-shaped plates 8. Operation is performed on the PLC control panel 2. The drive motor 5 is started, and its output shaft drives the forward and reverse lead screws 16 to rotate, thereby moving the two lead screw slides 17 inward and the two arc-shaped plates 8 inward. Four first electric hydraulic cylinders 7 are activated, each driving the elastic head 15 inward to compress and fix the upper and lower ends of the pipe, thus fixing different types of pipes and achieving quick-connect connection. This adapts to the production needs of different pipes and improves the applicability of the tooling. The second electric hydraulic cylinder 10 is activated, moving the mounting base 11 forward, thereby causing the two arc-shaped plates 8 to move back and forth, adjusting the pipe position. The high-temperature resistant heat-insulating coating 14 further enhances the performance of the two arc-shaped plates. The high-temperature resistance of the inner wall of the arc plate 8 prevents high temperatures from affecting the arc plate 8. The rubber layer 13 improves the elasticity inside the arc plate 8, preventing the pipe from being squeezed and deformed. The stainless steel 12 ensures stability and durability under high temperature and high pressure environments. The dual-head motor 18 is started, which drives the two output rods 21 to rotate, which in turn drives the bevel gear 20 to rotate, thereby driving the two connecting shafts 19 to rotate, which in turn drives the roller 4 to rotate, realizing the movement of the device position, bringing convenience and flexibility. The lifting chamber 1 is made of aluminum alloy material and is formed by hot extrusion process, resulting in a lighter weight for the same volume and better structural heat dissipation. The aluminum alloy shell formed by hot extrusion process has strong corrosion resistance and good oxidation resistance. In humid air, it can form an oxide film to prevent metal corrosion, thereby improving service life.
