Technical Field

[0001] This utility model relates to the field of hot pressing mold technology, specifically a rapid cooling system for silicone rubber hot pressing molds. Background Technology

[0002] Hot pressing is a simple and commonly used molding method for high-temperature vulcanized silicone rubber. The mold is heated, the rubber compound is placed in the mold cavity, the mold is placed between heating plates, and the temperature is maintained for a certain time under certain pressure, so that the high-temperature vulcanized silicone rubber completes the vulcanization process and obtains the product of the required shape and size, thereby meeting the production and processing needs of vulcanized silicone rubber.

[0003] In the existing technology, the temperature of the rubber compound is too high after it is formed inside the hot pressing mold during the production of silicone rubber products. It needs to be cooled for a long time before it can be unloaded, which reduces the production efficiency of silicone rubber products. Therefore, a rapid cooling system for silicone rubber hot pressing molds is needed. Utility Model Content

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a rapid cooling system for a silicone rubber hot pressing mold, comprising an upper mold 1 and a lower mold 5, wherein both the upper mold 1 and the lower mold 5 are provided with an auxiliary heat dissipation mechanism 2.

[0024] The auxiliary heat dissipation mechanism 2 includes a mounting groove 6. A mounting frame 7 is slidably connected to the inner side of the mounting groove 6. The mounting groove 6 provides space for the installation of the auxiliary heat dissipation mechanism 2. A circulating water pipe 10 is provided inside the mounting frame 7. Water supply pipes 11 are connected through and fixedly to the left and right sides of the front wall of the mounting frame 7. The water supply pipes 11 can input cold water into the circulating water pipes 10. The cold water absorbs the heat in the mold during the movement inside the circulating water pipes 10 and leaves the circulating water pipes 10 from the right water supply pipe 11. A solenoid valve 12 is provided in the middle of the outer periphery of the left water supply pipe 11. An opening 13 is provided at the front end of the middle of the left and right walls of the mounting frame 7. A locking block 14 is slidably connected to the inner side of the opening 13. The locking block 14 can slide left and right inside the opening 13. Inserting the locking block 14 into the locking slot 19 can fix the mounting frame 7 inside the mounting groove 6. Limit rods 15 are fixedly connected to the middle of the side wall of the two sets of locking blocks 14 that are close to each other. Springs 18 are fixedly connected to the outer periphery of the side wall of the two sets of locking blocks 14 that are close to each other.

[0025] The limiting rods 15 all pass through and slide inside the limiting holes 16. The limiting holes 16 are all located in the middle of the U-shaped plate 17. The U-shaped plate 17 is fixed inside the mounting frame 7 to provide space for the installation of the limiting rods 15 and the limiting holes 16. The front wall of the mounting frame 7 is fixedly connected with handles 8.

[0026] Positioning rods 3 are fixedly connected to the four corners of the bottom wall of the upper mold 1, and positioning holes 4 are provided at the four corners of the top wall of the lower mold 5. The positioning rods 3 are all clearance-fitted with the positioning holes 4. A forming groove 9 is provided in the middle of the side wall of the upper mold 1 and the lower mold 5 that are close to each other. The positioning rods 3 and the positioning holes 4 can make the upper mold 1 and the lower mold 5 fit together.

[0027] The mounting groove 6 is located on the side away from the upper mold 1 and the lower mold 5. The front end of the middle of the left and right walls of the mounting groove 6 is provided with a slot 19. The slot 19 is on the same horizontal line as the opening 13. The slot 19 is in clearance fit with the block 14. The block 14 can pass through the opening 13 and enter the slot 19, thereby fixing the mounting frame 7 inside the mounting groove 6.

[0028] Working principle: An installation groove 6 is provided inside the upper mold 1 and the lower mold 5. An installation frame 7 and a circulating water pipe 10 are installed inside the installation groove 6. With the cooperation of the circulating water pipe 10, the water supply pipe 11 and the solenoid valve 12, cold water can be filled into the circulating water pipe 10 to quickly cool the mold. At the same time, the flow rate of water in the circulating water pipe 10 can be controlled by the solenoid valve 12, thereby controlling the cooling rate of the rubber. When the auxiliary heat dissipation mechanism 2 malfunctions, the locking block 14 is pushed inward to pull out from the locking groove 19, so that the installation frame 7 can slide inside the installation groove 6. After the installation frame 7 is removed from the installation groove 6, the circulating water pipe 10 inside the installation frame 7 can be inspected and repaired.
