Description

Technical Field

[0001] This utility model relates to the field of door insulation shell technology, and in particular to a door insulation shell mold. Background Technology

[0002] In the construction and home furnishing industry, door insulation shells are core functional components, and their manufacturing precision and quality directly affect the door's heat insulation, sound insulation performance, and overall service life. These shells are typically manufactured from metal sheets through stamping dies in one or more stages. However, existing stamping dies cannot eject the shell after stamping, making it inconvenient to remove the die. To address this, patent announcement number CN216420844U discloses "a stamping die for a shell." This solution uses a first cylinder, a push rod, and a top plate. After the shell is stamped, the first cylinder lifts the push rod, which then pushes the die out through the top plate. The top plate features an ejector mechanism for easy mold removal and convenient operation. Limiting blocks and grooves ensure stability during the lifting and lowering of the top plate. A second cylinder and a limiting rod allow the upper mold to be driven for stamping, while the limiting rod enhances stability during lifting and lowering. A insert rod and slot allow for easy disassembly and cleaning of the upper mold after use; bolts and a slider facilitate the disassembly of the lower mold, while the bolts secure it, maintaining stability during stamping.

[0003] However, in this scheme, during the high-speed continuous stamping production process, there will be severe friction between the metal sheet and the mold. At the same time, the material itself will also generate a lot of heat due to plastic deformation. This heat will quickly accumulate on the mold, especially the lower mold that directly supports and forms the material, causing its temperature to rise sharply. The high temperature will accelerate the wear and thermal fatigue of the lower mold, causing slight changes in its cavity size. This will directly cause the warping and deformation of the shell parts, affecting the assembly accuracy with other heat insulation materials in the door body, thereby reducing the overall heat insulation performance of the door. Therefore, a heat insulation shell mold for doors is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a door insulation shell mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating shell mold for doors, including a processing table, a lower mold fixedly connected to the upper surface of the processing table by bolts, a water tank fixedly connected to one side of the processing table, a heat dissipation cavity opened in the inner wall of the lower mold, a plurality of support plates fixedly connected inside the heat dissipation cavity, a plurality of through holes opened on one side of each support plate, and a water inlet pipe and a water outlet pipe fixedly connected to the opposite sides of the lower mold, respectively. Through the heat dissipation cavity and the support plates, the cooling efficiency of the lower mold is enhanced, and the structural stability of the lower mold is improved.

[0006] As a further description of the above technical solution: One end of the water inlet pipe is fixedly connected to a first pair of connecting pipes, and one end of the first pair of connecting pipes is fixedly connected to a first flexible hose.

[0012] This utility model has the following beneficial effects: 1. Compared with existing technologies, this door uses a heat-insulating shell mold. By setting up a heat dissipation cavity, support plate, water inlet pipe, water outlet pipe, first connecting pipe, first flexible hose, connecting pipe, water pump, second connecting pipe, second flexible hose, and return water pipe, the water pump in the water tank is started. The coolant is pumped out through the connecting pipe, and enters the heat dissipation cavity opened inside the lower mold through the first flexible hose and the first connecting pipe. When the coolant flows through the heat dissipation cavity, it can fully and evenly absorb and carry away the large amount of heat generated by the lower mold due to stamping friction and material deformation through the flow channels formed by the support plate and its through holes. After absorbing heat, the coolant returns to the water tank through the water outlet pipe, the second connecting pipe and the second flexible hose, and finally through the return water pipe. This avoids the lower mold temperature from rising sharply, which would cause the shell parts to warp and deform, affecting the assembly accuracy with other heat-insulating materials in the door body.

[0013] 2. Compared with the existing technology, the door uses a heat-insulating shell mold, and by setting up heat dissipation plates, rotating rods, servo motors and stirring plates, the servo motor drives the rotating rods and stirring plates to rotate, accelerating the flow and heat exchange of the coolant inside the water tank, while multiple heat dissipation plates fixed on the tank wall further dissipate heat into the air, achieving continuous cooling of the coolant and ensuring the cooling effect of the coolant.

[0017] Reference Figures 1 to 7This utility model provides a door insulation shell mold, comprising a processing table 1, a lower mold 2 fixedly connected to the upper surface of the processing table 1 by bolts, a water tank 3 fixedly connected to one side of the processing table 1, a placement frame 19 fixedly connected to the bottom of the processing table 1, a first cylinder 20 fixedly connected to the inner bottom of the placement frame 19, a limit plate 21 fixedly connected to the piston end of the first cylinder 20, the limit plate 21 being slidably connected to both sides inside the placement frame 19, two push rods 22 fixedly connected to the upper surface of the limit plate 21, the two push rods 22 penetrating the processing table 1 and the lower mold 2 and being slidably connected, a top plate 23 being fixedly connected to the upper surface of the two push rods 22, the top plate 23 being slidably connected to the inner wall of the lower mold 2, and the first cylinder 20 inside the placement frame 19 being activated, its piston rod pushing the limit plate 21 upward, the limit plate 21 sliding stably along the inner wall of the placement frame 19. The top plate 23 moves upward synchronously, and the top plate 23 pushes the formed door out of the cavity of the lower mold 2 smoothly with the heat insulation shell, so as to facilitate the operator to pick up the part and prepare for the next stamping cycle. The upper surface of the processing table 1 is fixedly connected to the mounting frame 24, the upper surface of the mounting frame 24 is fixedly connected to the second cylinder 25, the piston end of the second cylinder 25 is fixedly connected to the connecting plate 26, the bottom of the connecting plate 26 is fixedly connected to the upper mold 27 through the insert rod, and the upper surface of the connecting plate 26 is fixedly connected to two limit rods 28. Each limit rod 28 passes through the upper surface of the mounting frame 24 and is slidably connected. When the second cylinder 25 is started, its piston rod pushes the connecting plate 26 and the upper mold 27 fixed thereto to move downward. Under the guidance of the limit rod 28, the upper mold 27 and the lower mold 2 close, completing the stamping of the sheet metal. To achieve cooling, a heat dissipation cavity 4 is formed on the inner wall of the lower mold 2. Multiple support plates 5 are fixedly connected inside the heat dissipation cavity 4. Multiple through holes are formed on one side of each support plate 5. A water inlet pipe 6 and a water outlet pipe 7 are fixedly connected to opposite sides of the lower mold 2. A first pair of connecting pipes 8 are fixedly connected to one end of the water inlet pipe 6, and a first flexible hose 9 is fixedly connected to one end of the first pair of connecting pipes 8. A water pump 11 is fixedly connected to the bottom of the water tank 3. A connecting pipe 10 is fixedly connected to the outlet of the water pump 11. The connecting pipe 10 passes through one side of the water tank 3 and is fixedly connected. One end of the connecting pipe 10 is fixedly connected to one end of the first flexible hose 9. A second pair of connecting pipes 12 are fixedly connected to one end of the water outlet pipe 7, and a second flexible hose 13 is fixedly connected to one end of the second pair of connecting pipes 12. One end of 13 is fixedly connected to a return water pipe 14, which passes through one side of the water tank 3 and is fixedly connected. When the water pump 11 in the water tank 3 is started, the coolant is pumped out through the connecting pipe 10, and enters the heat dissipation cavity 4 inside the lower mold 2 through the first hose 9 and the first connecting pipe 8. When the coolant flows through the heat dissipation cavity 4, it can fully and evenly absorb and carry away a large amount of heat generated by the lower mold 2 due to stamping friction and material deformation through the flow channel formed by the support plate 5 and its through holes. After absorbing heat, the coolant returns to the water tank 3 through the outlet pipe 7, the second connecting pipe 12 and the second hose 13, and finally through the return water pipe 14. This prevents the temperature of the lower mold 2 from rising sharply, which would cause the shell parts to warp and deform, affecting the assembly accuracy of the shell parts with other heat insulation materials inside the door. To achieve the purpose of stirring, multiple heat dissipation plates 15 are fixedly connected to the opposite side of the water tank 3. Each heat dissipation plate 15 extends to the inner wall of the water tank 3. A rotating rod 16 is rotatably connected to the inner side of the water tank 3, and a servo motor 17 is fixedly connected to the outer side of the water tank 3. The servo motor 17 is electrically connected to an external controller for easy control of its operation. The output shaft of the servo motor 17 is fixedly connected to one end of the rotating rod 16. Multiple stirring plates 18 are fixedly connected to the rotating rod 16. The servo motor 17 drives the rotating rod 16 and the stirring plates 18 to rotate, accelerating the flow and heat exchange of the coolant inside the water tank 3. The multiple heat dissipation plates 15 fixed to the tank wall further dissipate heat into the air, achieving continuous cooling of the coolant and ensuring its cooling effect.

[0018] Working principle: The water pump 11 in the water tank 3 is started, and the coolant is pumped out through the connecting pipe 10. It enters the heat dissipation cavity 4 inside the lower mold 2 through the first hose 9 and the first connecting pipe 8 and the water inlet pipe 6. When the coolant flows through the heat dissipation cavity 4, it can fully and evenly absorb and carry away the large amount of heat generated by the lower mold 2 due to stamping friction and material deformation through the support plate 5 and the through holes on it. After absorbing heat, the coolant returns to the water tank 3 through the water outlet pipe 7, the second connecting pipe 12 and the second hose 13, and finally through the return pipe 14. This prevents the temperature of the lower mold 2 from rising sharply, which would cause the shell parts to warp and deform, affecting the assembly accuracy with other heat insulation materials in the door body. At the same time, the servo motor 17 drives the rotating rod 16 and the stirring plate 18 to rotate, accelerating the flow and heat exchange of the coolant inside the water tank 3. The multiple heat dissipation plates 15 fixed on the tank wall further dissipate the heat into the air, achieving continuous cooling of the coolant and ensuring the cooling effect of the coolant.
