[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This plastic release mold with a heat dissipation structure is equipped with a water valve, a water outlet pipe, a water valve, a water collection tank, a suction fan, and a heat dissipation channel. During the molding process, opening water valve one allows water from the storage tank to reach the bottom of the mold through the water inlet pipe. As heat is generated during processing, the water passing through the mold absorbs most of the heat until processing is complete. Opening water valve two connects the water outlet pipe to the water inlet pipe, allowing the heat-absorbing water to be channeled into the water collection tank. Once the water in the collection tank cools, it can be reused, reducing water waste. The suction fan extracts the heat generated during processing through the air vents on the partition and discharges it through the heat dissipation channel, maintaining a suitable working temperature inside the mold and significantly reducing water waste while reducing workload.

[0014] 2. This plastic demolding mold with a heat dissipation structure, by setting up a drive motor, rotating roller, guide roller, limiting ring, spring, and sealing plate, allows the raw material to be molded to be poured into the bottom mold. The drive motor drives the rotating roller, causing the belt to move up and down on the rotating roller. Because the support and guide roller can support and fix the belt, the belt can lift and lower the mold with the cooperation of the rotating roller. At the same time, the limiting ring can support and limit the rotating roller, further improving work efficiency. During the demolding process, the air pump passes air into the air groove through the air pipe, causing the air groove to be pressurized and squeeze the sealing plate outward. Thus, the top plate is squeezed out of the molded workpiece completely under the pressure of the sealing plate. The elastic force of the spring provides a rebound support to the connecting rod, allowing the connecting rod to reset the ejected sealing plate, thereby completing the demolding operation and facilitating the complete removal of the molded workpiece from the mold.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a plastic demolding mold with a heat dissipation structure, including a workbench 1, a water collection tank 206 at the bottom of the workbench 1, a water outlet pipe 204 fixedly connected to the top of the water collection tank 206, the top of the water outlet pipe 204 penetrating the bottom of the workbench 1 and connected to a water inlet pipe 203, and a water valve 205 on the outside of the water outlet pipe 204. By providing the water valve 205, turning the water valve 205 causes the water to move away from the bottom of the workbench 1, thereby allowing the heat-absorbing water inside the workbench 1 to be discharged.

[0024] A water-cooling assembly 2 is fixedly installed on the top of the workbench 1. The water-cooling assembly 2 includes a water storage tank 201. A water inlet pipe 203 is fixedly connected to one side of the water storage tank 201. A water valve 202 is installed on the top of the water inlet pipe 203. A box body 3 is fixedly installed on the top of the workbench 1. Supports 12 are respectively provided on both sides of the box body 3 at the positions corresponding to the belts 10. There are eight supports 12, and each belt 10 corresponds to two supports 12. One end of the support 12 and one end of the fixed block 11 are hinged to a guide roller 13 by a pin. The guide roller 13 is slidably connected to one side of the belt 10. Because of the guide roller 13, when the belt 10 is retracted and extended by the rotating roller 8, it passes through the connection between the two sets of supports 12 and guide roller 13, so that the bottom of the belt 10 can move synchronously with the rotating roller 8, ensuring that the process of the mold 4 being lifted and pressed down in the box body 3 is more stable.

[0025] A pressure mold 4 is installed inside the housing 3. A bottom mold 5 is installed at the bottom of the pressure mold 4. The bottom of the bottom mold 5 is fixedly connected to the top of the workbench 1. A blower box 6 is fixedly installed on one side of the housing 3. A partition 23 is provided on the side of the blower box 6 near the housing 3. Several air holes 24 are opened on the partition 23. A heat dissipation groove 26 is opened on the side of the blower box 6 away from the housing 3. Through the air holes 24, the demolding mold is cooled down during processing by the heat dissipation effect of the air holes 24, ensuring that the demolding mold can maintain a suitable temperature during processing and reducing damage to the molded workpiece.

[0026] A drive motor 7 is fixedly installed on the top of the air box 6. A rotating roller 8 is fixedly connected to the output end of the drive motor 7. A limiting ring 9 is sleeved on the outside of the rotating roller 8. The bottom of the limiting ring 9 is fixedly connected to the top of the box 3. There are three limiting rings 9. By providing the limiting rings 9, the limiting rings 9 can support and fix the rotating roller 8, preventing the rotating roller 8 from shifting position and affecting the stability of the belt 10 movement.

[0027] A belt 10 is fixedly connected to the outside of the rotating roller 8. There are two sets of belts 10, which are symmetrically arranged about the center of the rotating roller 8. Each set of belts 10 consists of two belts. The belts 10 are connected to the mold 4, and the other end of the belts 10 is fixed to the rotating roller 8. Through the cooperation between the rotating roller 8 and the drive motor 7, the drive motor 7 drives the rotating roller 8 to rotate, so that the belts 10 can be rolled up and down on the rotating roller 8. This facilitates the synchronous adjustment of the mold 4 and the multiple belts 10.

[0028] A fixing block 11 is fixedly installed on the housing 3 at the position corresponding to the belt 10. The bottom of the belt 10 passes through a square groove 14 and is fixedly connected to the pressing mold 4. An air pump 15 is fixedly installed on the top of the pressing mold 4. An air pipe 16 is fixedly connected to the air outlet of the air pump 15. The air pipe 16 is I-shaped, and all four ends of the air pipe 16 pass through the top of the pressing mold 4. An air groove 17 is opened in the top of the pressing mold 4 at the position corresponding to the air pipe 16. A housing 18 is fixedly installed on the inner top of the air groove 17. A spring 19 is installed inside the body 18. Because the spring 19 is connected to the top of the connecting rod 20 and the air groove 17, the gas introduced through the air pipe 16 causes the sealing plate 21 to push the top plate 22 outward, so that the top plate 22 can discharge the molding die more completely. Because the spring 19 can exert a spring force on the connecting rod 20, the gas is no longer compressed after the sealing plate 21 is opened, so that the connecting rod 20 and the top plate 22 are reset by the spring 19, improving the demolding efficiency while ensuring the demolding effect.

[0029] A connecting rod 20 is fixedly installed at the bottom of the spring 19, a sealing plate 21 is fixedly installed at the bottom of the connecting rod 20, and a top plate 22 is fixedly installed at the bottom of the sealing plate 21. The bottom of the top plate 22 is flush with the bottom of the mold 4. A suction fan 25 is installed inside the air box 6. Because of the suction fan 25, the heat generated by the demolding mold processing can be extracted, reducing the working environment temperature. The heat dissipation groove 26 can exhaust the extracted hot air, ensuring that the demolding process is kept at a suitable temperature.

[0030] The working principle of this utility model is as follows:

[0031] After filling the water storage tank 201 with water and tightening the water valve 202 on the water inlet pipe 203, pour the workpiece material to be processed into the bottom mold 5. Then, start the drive motor 7 so that its output shaft drives the rotating roller 8 to rotate, which in turn drives the belt 10 to move up and down. The limiting ring 9 can support and limit the rotating roller 8, so that multiple sets of belts 10 can simultaneously drive the pressing mold 4 to rise and fall within the box 3. Controlling the opening and closing of the water valve 202 allows water to flow through the water inlet pipe 203 to the bottom mold 5. The heat of the bottom mold 5 is absorbed by water cooling. Turning the water valve 205 allows the wastewater to be discharged into the water collection tank 206 through the water outlet pipe 204, so that the cooled water can be reused for mold removal operations. The air pump 15 is started, allowing gas to enter the air groove 17 through the air pipe 16. Due to the sealed environment of the sealing plate 21, the air groove 17 is pressurized. Then, the sealing plate 21 drives the top plate 22 to push out of the air groove 17, extruding the workpiece completely from the surface of the mold 4. Finally, the air pump 15 is turned off to balance the pressure in the air groove 17. The elastic force of the spring 19 can fix and reset the connecting rod 20, thereby allowing the connecting rod 20 to reset the sealing plate 21, facilitating the next demolding operation. By starting the suction fan 25 in the air box 6, the heat generated by the process can be extracted in conjunction with the air holes 24 on the partition plate 23, and the hot air can be discharged through the heat dissipation groove 26, maintaining the circulation of cold air in the processing environment.
