[0002] Injection molds are tools used in the injection molding process. Molten plastic is injected into the mold cavity, and after cooling, plastic products of the desired shape and size are obtained. Cooling of injection molds usually requires the use of a water chiller. The water chiller achieves the cooling effect of the injection mold in the water tank by cooling and circulating water.

[0003] After the mold is cooled in the water tank of the water chiller, the user needs to remove the mold from the water tank. To prevent problems such as scale and corrosion, it is usually necessary to wipe the water droplets on its surface with an absorbent towel in time. This process is usually done manually and is tedious. Therefore, a water cooling device for injection molds is proposed to address the above problems. Utility Model Content

[0022] A water cooling device for injection molds includes a water chiller 1 for cooling the mold. The water chiller 1 includes a frame 11, a water tank 12, and a drive assembly 13. The drive assembly 13 is located on one side of the frame 11, and the water tank 12 is fixedly connected to the top of the frame 11. A perforated frame 3 for filtering water is provided inside the water tank 12. A limit plate 4 is fixedly connected to the top of the perforated frame 3, and a first electric telescopic rod 5 is fixedly connected to the top of the limit plate 4. One end of the first electric telescopic rod 5 passes through a bracket 2 composed of several vertical plates, a top plate, and a bottom plate. A wiping assembly 6 is located below the top plate of the bracket 2. The wiping assembly 6 includes a second electric telescopic rod 61, a reciprocating screw 62, a moving block 63, a bevel gear 64, a fixed plate 65, a sponge roller 66, a fixed block 67, and a motor 68. A groove is formed at the bottom of the top plate of the bracket 2. 8. A movable block 63 is slidably connected in the groove 8 at the bottom of the top plate of the bracket 2. A reciprocating screw 62 is provided in the movable block 63. One end of the reciprocating screw 62 is fixedly connected to one of the bevel gears 64. One of the bevel gears 64 meshes with another bevel gear 64. The output shaft of the motor 68 is fixedly connected to the top of the other bevel gear 64. A second electric telescopic rod 61 is provided at the bottom of the movable block 63. A fixed plate 65 is fixedly connected to the bottom of the second electric telescopic rod 61. Fixed blocks 67 are fixedly connected to the front and rear sides of the bottom of the fixed plate 65. A sponge roller 66 is rotatably connected to one side of the fixed block 67. With the fan 7 and the wiping component 6 that can move back and forth, the tedious process of manually removing the mold and wiping the water droplets on its surface with a water-absorbing towel or other tools is avoided.

[0023] The base plate of bracket 2 is fixedly connected to the left and right sides of water tank 12. A fan 7 is fixedly connected to one side of the vertical plate of bracket 2 to enhance the wiping effect, which facilitates the fixation of bracket 2 and improves the water droplet cleaning effect. A reciprocating screw 62 is rotatably connected in the groove 8 opened at the bottom of the top plate of bracket 2. The output shaft of motor 68 passes through the top plate of bracket 2 to facilitate the rotation of reciprocating screw 62. Several sets of fixing blocks 67 are distributed below fixing plate 65 in pairs. A sponge roller 66 is rotatably connected between the two fixing blocks 67 to facilitate the rotation of sponge roller 66. The front plate of hollow frame 3 is rotatably connected to the bottom plate of hollow frame 3. A hand-tightening bolt 9 is provided on one side of the front plate of hollow frame 3 to facilitate the removal of mold.

[0024] Workflow: When using the water cooling device for injection molds, first place the water chiller 1 in a suitable position, fill the water tank 12 with water, and start the drive assembly 13 of the water chiller 1 to put it into working condition. Place the mold to be cooled in the hollow frame 3 inside the water tank 12 for effective cooling. After cooling is complete, the user starts the first electric telescopic rod 5. Since the first electric telescopic rod 5 is fixedly connected to the limiting plate 4 and the limiting plate 4 is fixedly connected to the hollow frame 3, it drives the hollow frame 3 to move upward. After moving to a suitable position, the water in the hollow frame 3 falls into the water tank 12 from the hollow parts of its side plate and bottom plate. At this time, the second electric telescopic rod 61 is started, which drives the fixed plate 65 and the sponge roller 66 to move downward until they are in contact with the mold surface. The motor 68 is started. Since the output shaft of the motor 68 and one of the bevel gears 64 are fixedly connected... The fixed connection, the two bevel gears 64 meshing with each other, and the other bevel gear 64 fixedly connected to the reciprocating screw 62, drive the moving block 63 to move back and forth in the groove 8. Since the sponge roller 66 is rotatably connected to the fixed block 67, the sponge roller 66 rotates and moves to wipe the water droplets on the mold surface. Then the fan 7 is turned on, and the generated air force dries the mold through the hollow part of the hollow frame 3. After the water droplets on the mold surface are wiped or dried, the user holds the hand-tightening bolt 9 and turns it in the loosening direction until it is taken out. Then the front plate of the hollow frame 3 is opened and the mold is taken out, completing the cleaning of the water droplets on the mold surface. With the set fan 7 and the wiping component 6 that can move back and forth, the tedious process of manually taking out the mold and wiping the water droplets on its surface with water-absorbing towels and other tools is avoided.
