Description

Technical Field

[0001] This utility model relates to the field of air conditioning insulation pipe production, and in particular to an air conditioning insulation pipe foaming molding device. Background Technology

[0002] Air conditioning insulation pipes, also known as air conditioning rubber and plastic insulation pipes, are insulation materials used in air conditioning systems to wrap refrigerant copper pipes and condensate pipes. They are primarily used to maintain stable temperatures of the medium within the pipes, prevent heat loss, and avoid condensation. Air conditioning insulation pipes are key auxiliary materials for ensuring efficient air conditioning operation. They achieve energy saving and system protection through heat insulation and condensation prevention. When selecting insulation pipes, attention should be paid to thickness, flame retardancy, and material sealing. The foaming process of air conditioning insulation pipes involves a chemical reaction of polyurethane raw materials under specific process conditions to form a closed-cell insulation layer. This process typically involves injecting the raw material into the gap between the working metal pipe and the outer protective layer using a high-pressure foaming machine to form the insulation layer.

[0003] For example, patent number (CN221496857U) discloses a foaming device for processing thermal insulation pipes, relating to the field of thermal insulation pipe processing technology. It includes a main body for the thermal insulation pipe foaming device, comprising a raw material mixing mechanism and a heating and discharging mechanism. The raw material mixing mechanism includes a mixing and stirring unit, and the heating and discharging mechanism includes a heating and pushing unit and a vibrating foaming mold unit. This invention integrates the three steps of mixing, heating, and foaming molding, avoiding the problem of material hardening during the transport of high-temperature raw materials and increasing the practicality of the device. After the raw materials are evenly mixed, the control valve at the outlet of the raw material mixing cylinder is opened, allowing the raw materials to flow into the inner heating cylinder. An electric heating tube heats the material in the partition between the heating cylinder and the inner heating cylinder. The motor drives the spiral pusher to rotate, extruding the heated material and directly discharging it into the foaming mold for foaming.

A support slide rod 15 is fixedly installed on the upper end of the mounting plate 10, which is located in front of the electric displacement guide rail 11. The connecting plate 7 is driven to rise by the telescopic cylinder 6, so that the positioning column 14 and the sealing stripping top plate 5 rise synchronously to complete the stripping operation of the air conditioning insulation pipe foam molding process. It provides multiple support stripping areas, so that the insulation layer and metal pipe of the air conditioning insulation pipe can rise synchronously under force, so that the air conditioning insulation pipe is subjected to more uniform force during stripping, and avoids wear on the insulation layer due to uneven stripping force.

[0026] Please see Figures 1-4In this embodiment, the lower mold 3 is rotatably connected to the upper mold 4. A foaming feed module 16 is fixedly installed at the rear end of the lower mold 3. The sealing stripping top plate 5 is adapted to the lower mold 3. The upper end of the support rod 9 extends to the outside of the support base 2 and is fixedly connected to the sealing stripping top plate 5. The surface of the support rod 9 is slidably connected to the worktable 1. The telescopic cylinder 6 is used to drive the connecting plate 7 to rise and fall. A connecting sleeve 17 is fixedly installed inside the support base 2 on the side of the telescopic cylinder 6. A connecting sleeve rod 18 is provided on the inner side of the connecting sleeve 17. The upper end of the connecting sleeve rod 18 extends to the outside of the connecting sleeve 17 and is fixedly connected to the connecting plate 7. The connecting sleeve 17 and the support column 8 are evenly distributed. The surface of the connecting sleeve rod 18 is slidably connected to the connecting sleeve 17. The foaming molding device... A control module is installed on the device to control the operation of each driving component. The telescopic cylinder 6 can drive the connecting plate 7 to rise (the telescopic cylinder 6 can be set as a driving component with similar functions, and the control module of the device can control the operation of two telescopic cylinders 6 simultaneously). The connecting sleeve 17 and the connecting rod 18 limit and guide the connecting plate 7, which facilitates the improvement of the stability of the lifting and lowering operation of the connecting plate 7. The positioning column 14 can cooperate with the sealing stripping top plate 5 to rise synchronously (while the sealing stripping top plate 5 supports the insulation layer of the air conditioning insulation pipe, the positioning column 14 supports the metal pipe, and the two structural positions are relatively fixed. The sealing stripping top plate 5 can be adapted to the lower mold 3, and can ensure the flatness of the inner surface of the lower mold 3 in the retracted state), thus completing the stripping operation of the air conditioning insulation pipe foaming molding process.

[0027] Please see Figures 1-5 In this embodiment, the connecting plate 7 is slidably connected to the workbench 1, and the lower mold 3 and the upper mold 4 are both slidably connected to the surface of the positioning plate 13. The electric displacement guide rail 11 is used to drive the connecting frame 12 to move. The connecting frame 12 has an L-shaped structure design. The surface of the supporting slide rod 15 is slidably connected to the connecting frame 12. The metal pipe for processing air conditioning insulation pipe is placed between the two positioning columns 14. The electric displacement guide rail 11 can drive the connecting frame 12 to move (the electric displacement guide rail 11 can be set as a driving component with similar functions. The control module of the equipment can synchronously control the two electric displacement guide rails 11 to work and ensure that the moving directions are opposite). The positioning plate 13 and the positioning column 14 can move to the inside of the mold to clamp and position the metal pipe (the positioning plate 13 and the positioning column 14 are provided with a pressure balance structure to facilitate the balance of the air pressure inside and outside the mold and ensure that the equipment can carry out foaming molding processing normally. The positioning plate 13 and the positioning column 14 are adapted to the size of the metal pipe). The upper mold 4 can work and close in conjunction with the lower mold 3. The foaming feeding module 16 can inject material into the center of the mold structure.

[0028] During operation, the metal pipe used for air conditioning insulation pipe processing is placed between two positioning columns 14. The electric displacement guide rail 11 drives the connecting frame 12 to move, so that the positioning plate 13 and the positioning column 14 move to the inside of the mold, clamp the metal pipe, and complete the clamping and positioning of the metal pipe. The upper mold 4 is closed, and the material is injected in the center through the foaming feeding module 16. After the foaming molding process is completed, the upper mold 4 is opened, and the telescopic cylinder 6 drives the connecting plate 7 to rise. The connecting sleeve 17 and the connecting rod 18 limit and guide the connecting plate 7, which can improve the stability of the lifting and lowering of the connecting plate 7. The positioning column 14 and the sealing stripping top plate 5 rise synchronously to complete the stripping operation of the air conditioning insulation pipe foaming molding process.

[0029] Through the above steps, the telescopic cylinder 6 drives the connecting plate 7 to rise, so that the positioning column 14 and the sealing stripping top plate 5 rise synchronously, completing the stripping operation of the air conditioning insulation pipe foaming molding process. It provides multiple support stripping areas, so that the insulation layer and metal pipe of the air conditioning insulation pipe can rise synchronously under force, making the air conditioning insulation pipe more evenly stressed during stripping. This avoids wear on the insulation layer caused by uneven stripping force, thus solving the problem that the stripping part area is relatively concentrated and the stripping force is not even when the air conditioning insulation pipe foaming molding device is working, which easily causes wear on the air conditioning insulation pipe during the stripping process and affects the processing quality of the air conditioning insulation pipe.
