Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically a pipe connector mold. Background Technology

[0002] Pipe connector molds are specialized tools used to manufacture pipe connectors. Through mold forming, pipe connector products that meet requirements can be produced efficiently and precisely. They generally consist of a mold body and may include structures such as casting grooves, casting ports, mounting ears, and fixing holes. Some molds also incorporate reinforcing ribs to enhance strength. During the manufacturing process, they ensure the shape and dimensional accuracy of the connectors, guaranteeing product quality. Their applications are wide-ranging. In the construction industry, they can be used to manufacture water pipe joints and drainage pipe joints; in the water conservancy industry, they can be used to manufacture irrigation pipe joints and water supply pipe joints; in the chemical and petroleum industries, they can be used to manufacture corrosion-resistant and high-temperature-resistant chemical pipe joints and oil pipe joints, providing crucial support for the construction of pipeline systems in various industries.

[0003] The existing patent (publication number: CN221518665U) describes a mold that facilitates demolding. When the mold is in use, a cylinder is activated, which drives the slide plate and the lower mold base to move downward. The support plate holds the part in place, and the part is separated from the lower mold base, making it easy to demold. The mold uses a push plate lifting method to achieve demolding, but it is difficult to demold round or irregular workpieces by pushing the plate, which limits its applicability. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a pipe connector mold, which effectively solves the problem that the existing mold uses a push plate lifting method to achieve demolding, but round or irregular workpieces are difficult to demold by push plate lifting, and its application scope is limited.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe connector mold, comprising a workbench, a lower mold fixedly installed at the center of the top of the workbench, a support frame fixedly installed on one side of the top of the workbench, an electric push rod fixedly installed on the top of the support frame, the transmission end of the electric push rod penetrating downward through the support frame and fixedly installed with an upper mold, a servo motor fixedly installed on one side of the bottom of the workbench via a support plate, a material pipe fixedly installed on one side of the top of the upper mold via an injection valve, and air cylinders fixedly installed on both sides of the inside of the workbench via fixed sleeves, with air pipes fixedly installed at the ends of the two air cylinders that are close to each other. All pipes extend into the interior of the lower mold and are fixedly equipped with air valves. Both air valves are fixedly installed inside the lower mold. The surfaces of the two fixed sleeves are fixedly connected to the inner wall of one side of the worktable through fixed columns. Both air cylinders have pistons inside, and the circumferential surfaces of the pistons are in close contact with the inner walls of the air cylinders. The output end of the servo motor is equipped with a transmission assembly, which is connected to the two pistons. When the servo motor is running, it outputs power to the two pistons through the transmission assembly, causing the two pistons to move towards each other and compress the gas. A slide rod is fixedly installed on one side of the top of the upper mold, and a sliding sleeve is fitted on the surface of the slide rod. The sliding sleeve is fixedly installed on one side of the top of the support frame.

[0006] Preferably, the transmission assembly includes a drive sprocket, one side of which is rotatably connected to the inner bottom of the worktable via a positioning seat. A driven sprocket is provided on one side of the drive sprocket, and a chain is meshed between the driven sprocket and the drive sprocket. A shaft is fixedly installed in the middle of the driven sprocket, and the surface of the shaft is rotatably connected to the inner bottom of the worktable via four bushings.

[0007] Preferably, both ends of the shaft are fixedly mounted with driving bevel gears, one side of each driving bevel gear is meshed with a driven bevel gear, one side of each driven bevel gear is fixedly mounted with a transmission gear via a rotating rod, one side of each transmission gear is rotatably connected to the inner bottom of the worktable via a second rotating seat, and the other side of each driven bevel gear is rotatably connected to the inner bottom of the worktable via a first rotating seat.

[0008] Preferably, the upper part of each of the transmission gears is meshed with a rack, and one end of the bottom of each rack is fixedly mounted with a push-pull rod via a support arm. The sides of the two push-pull rods that are close to each other extend into the interior of the two air cylinders and are fixedly connected to the two pistons.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator starts the electric push rod to drive the upper mold to move down. When the upper mold moves down, it drives the slide rod to slide along the inside of the slide sleeve, which increases the stability of the lower mold when it moves. When the upper mold moves down, it will close with the lower mold. Then, the material is injected into the upper mold and the lower mold through the material pipe and the injection valve to cast the base plate. After the base plate is cast, the operator starts the electric push rod to drive the upper mold to move up and reset. Then, the servo motor is started to drive the drive sprocket to rotate along the positioning seat. When the drive sprocket rotates, it drives the driven sprocket to rotate through the chain. The driven sprocket drives the shaft to rotate inside the four bushings. When the shaft rotates, it drives the two driven bevel gears to rotate through the two drive bevel gears.

[0010] When the two driven bevel gears rotate, they drive the two transmission gears to rotate via two rotating rods. When the two transmission gears rotate, they drive the two support arms to move in opposite directions via two racks. When the two support arms move in opposite directions, they push the two piston discs along the inside of the two air cylinders via two push-pull rods. This forces pressurized gas into the lower mold through two air pipes and two air valves, ejecting the formed base plate. This allows the mold to effectively demold round or irregularly shaped workpieces to meet the needs of different processing and production, and it has a very good performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1 to 5 The present invention includes a workbench 1, a lower mold 2 fixedly installed at the center of the top of the workbench 1, a support frame 3 fixedly installed on one side of the top of the workbench 1, an electric push rod 4 fixedly installed on the top of the support frame 3, the transmission end of the electric push rod 4 passing downward through the support frame 3 and fixedly installed on an upper mold 5, a servo motor 11 fixedly installed on one side of the bottom of the workbench 1 via a support plate 10, a material pipe 9 fixedly installed on one side of the top of the upper mold 5 via an injection valve 8, and air cylinders 27 fixedly installed on both sides of the inside of the workbench 1 via fixing sleeves 30. Air pipes 28 are fixedly installed at the ends of the two air cylinders 27 that are close to each other, and both air pipes 28 extend into the interior of the lower mold 2 and are fixedly installed. Two air valves 29 are installed, and both air valves 29 are fixedly installed inside the lower mold 2. The surfaces of the two fixed sleeves 30 are fixedly connected to the inner wall of one side of the worktable 1 through the fixed column 31. The interior of the two air cylinders 27 is equipped with pistons 26, and the circumferential surface of the pistons 26 is in close contact with the inner wall of the air cylinders 27. The output end of the servo motor 11 is equipped with a transmission component, which is connected to the two pistons 26. When the servo motor 11 is running, it outputs power to the two pistons 26 through the transmission component, causing the two pistons 26 to move towards each other and compress the gas. A slide rod 6 is fixedly installed on one side of the top of the upper mold 5. A slide sleeve 7 is fitted on the surface of the slide rod 6, and the slide sleeve 7 is fixedly installed on one side of the top of the support frame 3.

[0021] In use, the operator activates the electric push rod 4 to move the upper mold 5 downwards. As the upper mold 5 moves downwards, it causes the sliding rod 6 to slide along the inside of the sliding sleeve 7, increasing the stability of the lower mold 5 during movement. When the upper mold 5 moves downwards, it will close with the lower mold 2. Then, the material is injected into the upper mold 5 and the upper mold 2 through the material pipe 9 and the injection valve 8 to cast the base plate. After the base plate is cast, the operator activates the electric push rod 4 to move the upper mold 5 upwards to reset it. Then, the servo motor 11 is activated to drive the transmission component to operate. When the transmission component operates, it pushes the two piston discs 26 to move along the inside of the two air cylinders 27, thereby squeezing the pressurized gas into the inside of the lower mold 2 through the two air pipes 28 and the two air valves 29 to eject the formed base plate. This allows the mold to effectively demold round or irregularly shaped workpieces to meet the needs of different processing and production, and has a very good performance.

[0022] The transmission assembly includes a drive sprocket 13, one side of which is rotatably connected to the inner bottom of the worktable 1 via a positioning seat 12. A driven sprocket 14 is provided on one side of the drive sprocket 13. A chain is meshed between the driven sprocket 14 and the drive sprocket 13. A shaft 15 is fixedly installed in the middle of the driven sprocket 14. The surface of the shaft 15 is rotatably connected to the inner bottom of the worktable 1 via four bushings 16.

[0023] The operator starts the servo motor 11 to drive the drive sprocket 13 to rotate along the positioning seat 12. When the drive sprocket 13 rotates, it drives the driven sprocket 14 to rotate through the chain. The driven sprocket 14 drives the shaft 15 to rotate inside the four bushings 16.

[0024] Both ends of the shaft 15 are fixedly mounted with driving bevel gears 17. One side of each driving bevel gear 17 is meshed with a driven bevel gear 18. One side of each driven bevel gear 18 is fixedly mounted with a transmission gear 20 via a rotating rod 19. One side of each transmission gear 20 is rotatably connected to the inner bottom of the worktable 1 via a second rotating seat 22. The other side of each driven bevel gear 18 is rotatably connected to the inner bottom of the worktable 1 via a first rotating seat 21. The upper part of each transmission gear 20 is meshed with a rack 23. One end of each rack 23 is fixedly mounted with a push-pull rod 25 via a support arm 24. The sides of the two push-pull rods 25 that are close to each other extend into the interior of the two air cylinders 27 and are fixedly connected to the two pistons 26.

[0025] When the shaft 15 rotates, it drives the two driven bevel gears 18 to rotate through the two driving bevel gears 17. When the two driven bevel gears 18 rotate, they drive the two transmission gears 20 to rotate through the two rotating rods 19. When the two transmission gears 20 rotate, they drive the two support arms 24 to move towards each other through the two racks 23. When the two support arms 24 move towards each other, they push the two piston discs 26 along the inside of the two air cylinders 27 through the two push-pull rods 25, thereby squeezing the pressurized gas into the inside of the lower mold 2 through the two air pipes 28 and the two air valves 29 to push out the formed bottom plate.
