Description

Technical Field

[0001] This application relates to the technical field of plastic mold cooling, and in particular to a plastic mold cooling device. Background Technology

[0002] Plastics are polymers made from monomers through addition or condensation polymerization. Commonly known as plastics or resins, they can have their composition and shape freely altered. They consist of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastic products are molded, and after molding, they require cooling. Traditional cooling methods are mostly single-batch cooling; once one batch of molds enters the cooling equipment, it must wait for cooling to complete before the next batch can be placed in. During this period, the cooling equipment is idle, and its critical components, such as the refrigeration system and water circulation system, cannot function continuously. This reduces equipment utilization and wastes resources. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a cooling device for plastic molds. (Refer to...) Figure 1-4 A plastic mold cooling device includes a cooling box 1 and a cooling mechanism. The cooling box 1 has an internal cavity. A first placement frame 5 and a second placement frame 17 are slidably installed inside the cooling box 1 and are fixedly connected. Multiple partitions 6 are fixedly installed at equal intervals inside the first and second placement frames 5 and 17. Multiple drainage holes 21 are provided on the bottom sides of the first and second placement frames 5 and 17. Mounting rods 16 are fixedly connected to opposite sides of the first and second placement frames 5 and 17, and a fixing rod 7 is fixedly connected between the two mounting rods 16. A driving mechanism for moving the fixing rod 7 is provided on the cooling box 1. The driving mechanism includes a drive motor 12 and a gear 13. The drive motor 12 is fixedly connected to one side of the cooling box 1 via a fixing bracket 11. The output end of the drive motor 12 is fixedly connected to the gear 13. Multiple tooth grooves 8 that mesh with the gear 13 are provided on the side wall of the fixing rod 7. The cooling mechanism includes... A water spray box 19 is fixedly connected to the top side of the interior of the cooling box 1. Multiple nozzles 20 are fixedly connected to the lower surface of the water spray box 19. The cooling box 1 is equipped with a liquid delivery mechanism for delivering coolant to the water spray box 19. The liquid delivery mechanism includes a water pump 2, an inlet pipe 3, and an outlet pipe 4. The water pump 2 is fixedly connected to the upper surface of the cooling box 1. One end of the inlet pipe 3 is fixedly connected to the input end of the water pump 2, and the other end of the inlet pipe 3 passes through the side wall of the cooling box 1 and extends into its interior. One end of the outlet pipe 4 is fixedly connected to the output end of the water pump 2, and the other end of the outlet pipe 4 passes through the top wall of the cooling box 1 and is fixedly connected to the water spray box 19. A filter screen 18 is movably installed inside the cooling box 1 to filter impurities in the coolant. An inlet 10 and a drain 14 are fixedly connected to one side of the cooling box 1. Two connecting rings 9 are fixedly connected to one side of the cooling box 1 through two connecting rods 15. The two connecting rings 9 are sleeved on the side wall of the fixed rod 7.

[0022] The implementation principle of the plastic mold cooling device in this application embodiment is as follows: When the electrical components appearing in this application are used, they are all connected to an external power supply and control switch. When in use, the operator can inject coolant into the cooling tank 1 through the water inlet 10. The plastic molds to be cooled are placed in the first placement frame 5 and the second placement frame 17 respectively. Multiple partitions 6 are fixedly installed at equal intervals inside the first placement frame 5 and the second placement frame 17. These partitions 6 can separate the molds to avoid collisions with each other, and at the same time, they can help the coolant to better contact the mold surface and improve the cooling effect. When the device is turned on, the drive motor 12 starts, and its output end drives the gear 13 to rotate. When the gear 13 rotates, it interacts with the tooth groove 8, causing the fixed rod 7 to move. Since the first placement frame 5 and the second placement frame 17 are fixedly connected to the fixed rod 7 through the mounting rod 16, the first placement frame 5 and the second placement frame 17 will move together with the fixed rod 7. Connecting rings 9 are fixedly connected to the two connecting rods 15 on one side of the cooling box 1. The connecting rings 9 are sleeved on the side wall of the fixed rod 7, which plays an auxiliary support and guiding role to ensure that the fixed rod 7 moves smoothly. In the initial state, the second placement frame 17 moves into the cooling box 1 and is located below the water spray box 19, ready for cooling. After water pump 2 is started, inlet pipe 3 draws in coolant from cooling tank 1, and then delivers coolant to spray box 19 through outlet pipe 4. Coolant is sprayed from nozzle 20, evenly spraying onto the plastic mold in second placement frame 17 to cool the mold. Coolant flows down from the mold surface, through multiple drain holes 21 on the bottom side of the second placement frame 17, and flows back into cooling tank 1, completing the coolant circulation. After the plastic mold in second placement frame 17 has cooled, drive motor 12 is started again. Drive motor 12 reverses, driving gear 13 to rotate in the opposite direction, causing fixed rod 7 to move in the opposite direction. Second placement frame 17 gradually moves out of cooling tank 1, while first placement frame 5 moves into the cooling tank 1, located below spray box 19. At this time, the plastic mold in first placement frame 5 begins to receive cooling, and the above cooling process is repeated. During the cooling process, filter screen 18 continuously filters impurities in the coolant to ensure the purity of the coolant. When the coolant needs to be replaced, the coolant in cooling tank 1 can be drained through drain port 14. In this process, by setting up a first placement frame 5 and a second placement frame 17, when the mold in the first placement frame 5 is cooling, the operator can place the mold to be cooled in the second placement frame 17. After the first placement frame 5 has cooled, the second placement frame 17 can quickly enter the cooling box 1 for cooling, realizing continuous cooling operation. This avoids the idleness of the equipment during traditional single-batch cooling, improves the utilization rate of the cooling equipment, and significantly improves the cooling efficiency.
