Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold cooling device. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of patterns and colors, shapes from simple to complex, sizes from large to small, and precise product dimensions. Products are easy to update and can be made into rubber and plastic parts with complex shapes.

[0003] When the current injection mold cooling device is in use, the water pump is turned on, and the water pump draws the water inside the tank into the circulation pipe through the water inlet pipe. Then the air conditioner is turned on, and then the fan is turned on. The fan rotates and draws the cold air generated by the air conditioner to blow onto the circulation pipe, and the high-temperature water is cooled through the circulation pipe. The cooled water enters the inside of the tank again to cool the injection mold. In this way, the fan is used to blow cold air to the surface of the circulation pipe to cool the circulation pipe. The cold air does not fully contact the outer surface of the circulation pipe, resulting in poor cooling effect on the circulation pipe. Utility Model Content

DETAILED DESCRIPTION

[0018] See also Figure 1-Figure 2 A cooling device for an injection mold comprises a support base 1 and a water tank 2 mounted on its upper end. A box body 3 is fixed to the rear end of the water tank 2. The rear end of the box body 3 is a box opening. A cooling fan 18 is fixed to the rear box opening of the box body 3. A sealing cover 11 is welded to the rear end of the water tank 2 and located inside the box body 3. A spiral circulation pipe 12 is provided inside the sealing cover 11. A pump 10 is fixed to the bottom of the box body 3. The water pumping end of the pump 10 is connected to a water pumping pipe 13. The end of the water pumping pipe 13 passes through the interior of the water tank 2 and is welded to the water tank 2. The lower part of the spiral circulation pipe 12 passes through the sealing cover 11 and is welded to the sealing cover 11. The drainage end of the pump 10 is connected to the lower part of the spiral circulation pipe 12. A drainage pipe 14 is fixed to the upper part of the spiral circulation pipe 12. The end of the water pump 13 is connected to a filter 15 by screws. The end surface of the drainage pipe 14 is located in the same plane as the inner wall surface of the water tank 2. The end of the drainage pipe 14 passes through the water tank 2 and is welded to the water tank 2. A plurality of semiconductor refrigeration sheets 16 are fixedly installed at the rear end of the sealing cover 11. The rear end of the semiconductor refrigeration sheet 16 is fixed. The heat dissipation fin 17 is installed, and a water supply pipe is installed on the upper end of the sealing cover 11. The water supply pipe can be threadedly connected to the pipe cover. After opening the pipe cover, cold water can be poured into the sealing cover 11 through the water supply pipe. Because the sealing cover 11 is welded and sealed with the water tank 2, water will not flow out of the sealing cover 11. Then the water supply pipe is sealed with the pipe cover. In this way, when the pump 10 uses the water pump pipe 13 to draw water into the water tank 2, and the pump 10 is connected to an external power supply, the filter 15 filters some waste chips, and then the water is discharged into the spiral circulation pipe 12 and flows along the spiral circulation pipe 12. The water in the sealing cover 11 is cooled by the semiconductor refrigeration sheet 16, so the spiral circulation tube 12 is immersed in the cooled water. When the spiral circulation tube 12 is cooled, the spiral circulation tube 12 is cooled overall, thereby improving the cooling effect of the spiral circulation tube 12. Then the cooled water in the spiral circulation tube 12 is discharged back to the water tank 2 from the drain pipe 14, thereby cooling the water circulation in the water tank 2. When the semiconductor refrigeration sheet 16 is used, the heat dissipation fins 17 cooperate with the heat dissipation fan 18 to dissipate heat for the semiconductor refrigeration sheet 16.

[0019] See also Figure 1-Figure 3 , the water tank 2 is slidably connected with a mesh plate 7, and a lifting mechanism 4 is fixed on both the front and rear sides of the left and right ends of the water tank 2. A cross bar 5 is fixed on the upper part of the lifting mechanism 4, and a vertical rod 6 is fixed at the lower end of the cross bar 5. The lower part of the vertical rod 6 is fixed to the upper part of the mesh plate 7. The lifting mechanism 4 includes a rectangular sleeve 41, a rectangular slide rod 42, and a threaded rod 43. The rectangular sleeve 41 is fixed to the water tank 2, and the rectangular slide rod 42 is slidably connected to the inside of the rectangular sleeve 41. A threaded channel 44 is provided in the middle of the rectangular slide rod 42. The upper part of the rectangular slide rod 42 is fixed to the cross bar 5, and the threaded rod 43 is threadedly connected to the inside of the threaded channel 44. The lower part of the threaded rod 43 passes through the rectangular sleeve 41 and is connected to the rectangular sleeve 41 bearing. Because the water in the water tank 2 is circulated To cool down, the injection mold is placed on the mesh plate 7, and then the threaded rod 43 is rotated clockwise. As the threaded rod 43 is threadedly engaged with the threaded channel 44, the rectangular slide bar 42 slides downward along the rectangular sleeve 41, so that the rectangular slide bar 42 drives the mesh plate 7 to move down into the water of the water tank 2 through the cross bar 5 and the vertical rod 6. As the injection mold enters the water, the injection mold is quickly cooled down. After the injection mold is cooled down, the threaded rod 43 can be rotated counterclockwise, and as the threaded rod 43 is threadedly engaged with the threaded channel 44, the rectangular slide bar 42 slides upward along the rectangular sleeve 41, so that the rectangular slide bar 42 drives the mesh plate 7 to move upward through the cross bar 5 and the vertical rod 6, so that the injection mold is moved out of the water. In this way, when taking out the injection mold, there is no need for the staff to take it out of the water, which is more labor-saving and convenient.

[0020] See also Figure 4A rotating shaft 19 is fixed to the lower part of the threaded rod 43, and a motor 20 is provided at the lower part of one of the rotating shafts 19. The output shaft of the motor 20 is fixed to the rotating shaft 19, and a first sprocket 21 and a second sprocket 23 are fixed to the upper and lower sides of the outer side of the rotating shaft 19 respectively. A first chain 22 is connected between the front and rear two first sprockets 21 on the same horizontal line, and a second chain 24 is connected between the left and right second sprockets 23 on the same horizontal line. The motor 20 is fixed to the side of the support base 1 through a bracket, and a pair of foot switches 8 are connected to the front of the motor 20 through wires. The foot switch 8 is located in front of the support base 1, and its motor 20 is externally powered, so that when one of the foot switches 8 is stepped on, the motor 20 can rotate forward, while stepping on the other foot switch 8 can make the motor 20 rotate forward. When the switch 8 is stepped on, the motor 20 can be reversed, so that one of the rotating shafts 19 is driven by the motor 20 to rotate clockwise or counterclockwise, and the rotating shaft 19 drives the corresponding threaded rod 43 to rotate clockwise or counterclockwise. When the rotating shaft 19 rotates, the first sprocket 21 and the first chain 22 cooperate to make the front and rear first sprockets 21 on the same horizontal line rotate synchronously, so that the front and rear rotating shafts 19 on the same horizontal line rotate synchronously, and then the second sprocket 23 and the second chain 24 cooperate to make the left and right second sprockets 23 on the same horizontal line rotate synchronously, so that the left and right rotating shafts 19 on the same horizontal line rotate synchronously, so that the four rotating shafts 19 can rotate synchronously, so that the four threaded rods 43 can rotate synchronously at the same time.
