Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a rapid cooling device for anti-deformation plastic mold products. Background Technology

[0002] Rapid cooling equipment for anti-deformation plastic molds is specifically designed for the mold cooling process in plastic molding. It aims to quickly and effectively reduce mold temperature, preventing deformation of the plastic product during cooling. This equipment typically consists of high-efficiency cooling pipes, a temperature control system, and a cooling medium pump, which can evenly guide the coolant to all parts of the mold, especially thin-walled or poorly ventilated areas.

[0003] Patent CN215039405U discloses a rapid cooling device for plastic mold processing. Specifically, the patent discloses a technical solution comprising: a base, a support mesh plate, a cooling box, a transmission cavity, and support legs. The cooling box is located at the center of the top of the base, and transmission cavities are located on the inner walls of both sides of the cooling box. A lead screw is rotatably connected to the center of the transmission cavity. A limiting groove is located on one side of the inner wall of the transmission cavity, with one end extending to the outside of the transmission cavity. A support mesh plate is located at one end of the cooling box. A drain port is located at the center of the bottom of the base, with the top of the drain port extending into the interior of the cooling box. Support legs are installed on both sides of the bottom of the base, and a horizontal plate is fixed below the base between adjacent support legs. The bottom of the horizontal plate has four sets of sliding structures. This technical solution achieves the technical effect of "not only reducing leakage during liquid injection in the cooling equipment and ensuring the integrity of the mold during use, but also improving the convenience of using the cooling equipment."

[0004] Because the existing equipment lacks a cooling water recycling function, the used cooling water is directly discharged through the drain port after the coolant is injected into the cooling tank during the cooling process of the plastic mold. This results in a large amount of cooling water being discarded after a single use and not being able to participate in the cooling process again, causing a huge waste of water resources.

[0005] Therefore, we propose a rapid cooling device for anti-deformation plastic mold products. Utility Model Content

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a rapid cooling device for anti-deformation plastic mold products, including a cooling box 1, which serves as the main container for the entire cooling process, providing cooling space for the plastic mold products and containing coolant to ensure that the cooling process takes place in a closed and stable environment. A motor 2 is fixedly installed on the top of the cooling box 1, providing power for the rotational movement of the entire device and serving as the core component driving the rotating assembly. The output end of the motor is coaxially fixedly connected to a first rotating shaft 3, which serves as a key component for power transmission, transmitting the rotational power of the motor 2 to the rotating assembly and providing mounting support for the first rotating seat 10.

[0028] A connecting pipe 20 is fixedly connected to the bottom of the cooling tank 1, and a nozzle 21 is fixedly connected to the top of the connecting pipe 20. This nozzle evenly sprays the coolant from the water tank 18 onto the plastic mold product inside the fixed cover 15 to achieve cooling. The bottom of the connecting pipe 20 is fixedly connected to the output end of the water pump 19. The connecting pipe 20 serves as a coolant delivery channel, guiding the coolant output by the water pump 19 to the nozzle 21. The water pump 19 is located inside the water tank 18, providing power for the circulation of the coolant in the water tank 18. The coolant is drawn out and delivered to the nozzle 21. The water tank 18 is used to store the coolant and provide sufficient cooling medium for the cooling process. At the same time, it is connected to the cooling tank 1 through the circulation pipe 22 to realize the recycling of the coolant. The input end of the water pump 19 is connected to the inside of the water tank 18. The circulation pipe 22 is fixedly connected to one side of the water tank 18 to return the coolant used in the cooling tank 1 to the water tank 18, realizing the recycling of the coolant. The end of the circulation pipe 22 away from the water tank 18 is fixedly connected to the bottom of the cooling tank 1.

[0029] The rotating assembly includes a first bevel gear 4, a fixed sleeve 5, a connecting rod 6, and a second bevel gear 7. The first bevel gear 4 is coaxially and fixedly connected to the outer circumference of the first rotating shaft 3. The first bevel gear 4 meshes with the second bevel gear 7, changing the direction of the rotational motion of the first rotating shaft 3 and transmitting it to the second bevel gear 7. The bottom of the first bevel gear 4 is provided with a fixed sleeve 5, which is fixed to the first rotating shaft 3 and serves as the connecting rod 6. The third bevel gear 8 provides mounting support and participates in the overall movement as part of the rotating assembly. The fixed sleeve 5 is rotatably connected to the outer periphery of the first rotating shaft 3. A connecting rod 6 is fixedly connected to one side of the fixed sleeve 5, connecting the fixed sleeve 5 and the second bevel gear 7. The second bevel gear 7 is installed in a suitable position and transmits part of the movement. The end of the connecting rod 6 away from the fixed sleeve 5 is rotatably connected to the second bevel gear 7 through a bearing, meshing with the first bevel gear 4 and the third bevel gear 8, further transmitting the movement transmitted from the first bevel gear 4 to the third bevel gear 8.

The third bevel gear is rotatably connected to the bottom of the fixed sleeve 5 through a bearing. The tooth surfaces of the third bevel gear 8 and the second bevel gear 7 mesh, transmitting the rotational movement of the second bevel gear 7 to the second rotating shaft 11. The bottom of the third bevel gear 8 is coaxially fixedly connected to the second rotating shaft 11, transmitting the rotational movement of the third bevel gear 8 to the second rotating seat 12, and providing mounting support for the second rotating seat 12.

[0030] A first rotating seat 10 is coaxially fixedly connected to the outer periphery of the first rotating shaft 3, and a second rotating seat 12 is coaxially fixedly connected to the outer periphery of the second rotating shaft 11. The bottoms of both the first rotating seat 10 and the second rotating seat 12 are rotatably connected to connecting seats 13 via bearings. A fixing cover 15 is connected to the first rotating seat 10 and the second rotating seat 12 via fastening rings 14, transmitting the movement of the first rotating seat 10 and the second rotating seat 12 to the fixing cover 15. Fastening rings 14 are movably connected to both sides of the connecting seat 13 to fix and clamp the fixing cover 15, ensuring that the fixing cover 15 will not loosen or fall off during rotation. Screws 23 are threaded to both sides of the two fastening rings 14, and the fixing cover 15 is fixedly installed at the bottom of the fastening rings 14. This cooling box 1 is used to place plastic mold products. Its outer grid structure facilitates full contact between the coolant and the product, improving cooling efficiency. At the same time, the rotation of the fixed cover 15 ensures that the product is cooled evenly during the cooling process, preventing deformation. Two fixed covers 15 work together. The outer periphery of the fixed cover 15 is a grid structure. The bottom of the fixed cover 15 is equipped with a nozzle 21. Multiple support rods 16 are fixedly installed at the bottom of the cooling box 1 to support the cooling box 1 and make it stably installed on the base plate 17. At the same time, they provide a certain height from the ground for the cooling box 1, which facilitates the operation and maintenance of the equipment. The end of the support rod 16 away from the cooling box 1 is fixedly connected to the base plate 17, which serves as the bottom support platform of the entire equipment and provides the installation foundation for the water tank 18 and the support rods 16, making the overall structure of the equipment more stable. The water tank 18 is fixedly installed on the top of the base plate 17.

[0031] The working process of this utility model:

[0032] Step 1: The operator starts the motor 2 and the water pump 19. The motor 2 starts to run, and its output end drives the first rotating shaft 3 to rotate, providing power for the entire rotational motion. The water pump 19 starts to work, drawing out the coolant from the water tank 18 to prepare for the circulation of the coolant.

[0033] Step two: The operator carefully places the plastic mold product to be cooled inside the fixing cover 15. Because the outer perimeter of the fixing cover 15 has a grid structure, it facilitates full contact between the coolant and the product, improving cooling efficiency. After placing the mold, the operator checks the tightness of the fixing cover 15 again to ensure that the mold will not fall off during rotation. The motor 2 drives the first rotating shaft 3 to rotate, which in turn drives the coaxially fixed first bevel gear 4 to rotate. The first bevel gear 4 meshes with the second bevel gear 7, transmitting the rotational motion to the second bevel gear 7. The second bevel gear 7 then meshes with the third bevel gear 8, further transmitting the motion to the third bevel gear 8. The second rotating shaft 11 at the bottom of the wheel 8 and the third bevel gear 8 rotates accordingly, driving the second rotating seat 12 to rotate. At the same time, the first rotating shaft 3 directly drives the first rotating seat 10 to rotate. The first rotating seat 10 and the second rotating seat 12 transmit motion to the fixed cover 15 through the connecting seat 13, the fastening ring 14 and the screw 23, so that the two fixed covers 15 drive the internal mold to rotate together. Meanwhile, the water pump 19 delivers the coolant in the water tank 18 to the nozzle 21 through the connecting pipe 20. The nozzle 21 sprays the coolant evenly on the rotating mold, so that the coolant is in full contact with the mold, achieving uniform cooling and preventing the mold from deforming.

[0034] Step 3: The used coolant flows back from the bottom of the cooling tank 1 to the water storage tank 18 through the circulation pipe 22. In the water storage tank 18, the coolant can be cooled naturally or by other auxiliary cooling methods so that it can be pumped out again by the water pump 19 for reuse, realizing the recycling of coolant. During the cooling process, the operator should pay close attention to the level and temperature of the coolant in the water storage tank 18 to ensure a continuous and stable supply of coolant and guarantee the cooling effect. When the mold is cooled to the required level, the operator first turns off the motor 2 to stop the rotating component, the fixed cover 15 and the mold from rotating, and then turns off the water pump 19 to stop the circulation of coolant. After the equipment has completely stopped running, the operator opens the cooling tank 1, carefully takes out the cooled plastic mold product, and performs subsequent processing or storage. Finally, the equipment is cleaned and maintained to prepare for the next use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
