[0001] The utility model relates to the technical field of molds, in particular to a silicone rubber mold with a post-molding cooling structure. Background Art

[0002] Silicone rubber mold is the simplest method in rapid mold making, with good elasticity and replication performance. In the use of silicone rubber mold, the silicone rubber solution is injected into the molding chamber of the mold, and naturally cooled and molded to make the required product. Since the cooling effect of natural cooling molding is poor and time-consuming, a cooling structure is provided in the silicone rubber mold to assist the mold cooling. There are many existing technologies for the cooling structure of silicone rubber mold:

[0003] For example, a silicone rubber mold with a post-molding cooling structure, disclosed in Chinese patent publication number CN217916548U, belongs to the mold field and includes a lower mold, movable columns are movably installed around the lower mold, an upper mold is movably installed above the movable columns, a molding chamber is fixedly installed in the middle of the lower mold, side water collecting tanks are fixedly installed on both sides of the lower mold, a first solenoid valve is fixedly installed on the side water collecting tank, a water inlet pipe is fixedly installed on the first solenoid valve, a second solenoid valve is fixedly installed below the side water collecting tank, a water outlet pipe is fixedly installed on the second solenoid valve, a water supply tank is installed at the lower end of the water outlet pipe, and through the water collecting tank and heat dissipation holes and other structures, after the cooling water cools the mold, the cooling water can leave the high-temperature area to avoid being further heated by the high-temperature area, and the cooling water is cooled through the heat dissipation holes to reduce the temperature of the cooling water. As time goes by, the temperature of the circulating cooling water is lowered, thereby maintaining a good cooling effect on the mold;

[0004] The cooling structure in the current silicone rubber mold is installed in the middle of the bottom end of the molding chamber. On the one hand, it can cool the bottom of the molding chamber and assist the mold in cooling and demolding. On the other hand, it can facilitate the cooling water to leave the high-temperature area and reduce the situation of continued heating by the high-temperature area. The cooling structure is installed at the bottom of the molding chamber, which is inconvenient for auxiliary cooling around the molding chamber, thereby affecting the cooling and demolding efficiency of the silicone rubber mold inside the molding chamber. In view of this, we propose a silicone rubber mold with a post-molding cooling structure. Utility Model Content

[0006] By providing a demoulding assembly inside the lower mold and a cooling assembly inside the demoulding assembly, the mold inside the molding bin can be quickly molded and demoulded, which effectively improves the demoulding efficiency of the mold. At the same time, by utilizing the inner bin opened inside the cooling net and filled with ice bags, the overall temperature of the cooling net can be reduced. When cooling water passes through the cooling net, it can further absorb the heat of the cooling water itself, thereby improving the cooling of the cooling water.

[0026] The cooling structure in the current silicone rubber mold is installed in the middle of the bottom end of the molding chamber. On the one hand, it can cool the bottom of the molding chamber, and on the other hand, it can facilitate the cooling water to leave the high-temperature area. However, the cooling structure installed at the bottom of the molding chamber is not convenient for auxiliary cooling around the molding chamber, thereby affecting the cooling and demolding efficiency of the silicone rubber mold inside the molding chamber.

[0027] See also Figure 1-Figure 5 As shown, the device includes a mold body 1, which is composed of an upper mold part 11 and a lower mold part 12. A movable column 13 is installed on the top of the lower mold part 12. The upper mold part 11 is sleeved on the surface of the movable column 13. A molding chamber 14 is opened in the middle of the lower mold part 12. A demolding component 2 is provided inside the lower mold part 12, and the other end of the demolding component 2 is installed on the surface of the lower mold part 12. A cooling component 3 for assisting in improving the demolding effect of the mold is installed inside the demolding component 2.

[0028] First, the specific structure of the demoulding assembly 2 is disclosed. The demoulding assembly 2 includes a flow groove 22 opened inside the lower mold 12. The flow groove 22 is located at the periphery of the molding chamber 14. A water tank 21 is movably installed on the surface of the lower mold 12. The inlet and outlet of the flow groove 22 are both connected to the inside of the water tank 21. A pump body 23 is installed on one side of the water tank 21. When the water tank 21 is installed on the surface of the lower mold 12, cooling water is injected into the inside of the water tank 21 through the cooling water inlet and outlet. The water tank 21 is connected to the flow groove 22 so that the cooling water can flow to the inside of the flow groove 22. The pump body 23 is used to facilitate the replacement of the cooling water inside the flow groove 22 with the cooling water inside the water tank 21, thereby improving the fluidity of the cooling water. The flow groove 22 surrounds the periphery of the molding chamber 14 on three sides, effectively improving the cooling effect on the molding chamber 14, wherein the pump body 23 is started by an external power supply.

[0029] Secondly, the specific structure of the cooling assembly 3 is disclosed. The cooling assembly 3 includes two mounting plates 31 mounted on the inner wall of the water tank 21. The two mounting plates 31 are provided with mounting grooves 33 on one side close to the inner cavity of the water tank 21. A cooling net 32 ​​is clamped between the two mounting grooves 33. The cooling net 32 ​​is made of aluminum. The two mounting plates 31 are arranged on the inner wall of the water tank 21, so that the cooling net 32 ​​can be clamped in the mounting grooves 33 provided on the surface of the mounting plates 31. When the cooling water in the circulation groove 22 flows to the inside of the water tank 21 through the pump body 23, the cooling water can pass through the surface of the aluminum cooling net 32. When the cooling water enters the inside of the circulation groove 22 again, its own heat can be absorbed by the cooling net 32, thereby improving the demolding efficiency of the mold inside the molding bin 14.

[0030] The improvement of this embodiment is that: first, the upper mold 11, the lower mold 12 and the movable column 13 are used to close the upper mold 11 and the lower mold 12, so that the silicone rubber mold can be formed inside the molding chamber 14. When the water tank 21 is installed on the surface of the lower mold 12, the cooling water is injected into the inside of the water tank 21 through the cooling water inlet and outlet. The water tank 21 is connected with the circulation groove 22 so that the cooling water can flow into the inside of the circulation groove 22. The pump body 23 is used to replace the cooling water inside the circulation groove 22 with the cooling water inside the water tank 21, thereby improving the cooling water efficiency. The flow groove 22 surrounds the periphery of the molding bin 14 on three sides, which effectively improves the cooling effect on the molding bin 14. The two mounting plates 31 arranged on the inner wall of the water tank 21 are used to make the cooling net 32 ​​snap into the mounting groove 33 opened on the surface of the mounting plate 31. When the cooling water inside the flow groove 22 flows into the water tank 21 through the pump body 23, the cooling water can pass through the surface of the aluminum cooling net 32. When the cooling water enters the inside of the flow groove 22 again, its own heat can be absorbed by the cooling net 32, thereby improving the demolding efficiency of the mold inside the molding bin 14.

[0031] Considering the cooling effect of the cooling net 32 ​​on the cooling water, in order to further improve the cooling of the cooling water and thus improve the demoulding effect of the mold, Figure 4-Figure 5 As shown, an inner compartment 4 is provided inside the cooling net 32 ​​, and the inner compartment 4 is filled with ice packs 41 .

[0032] The improvement lies in: by utilizing the inner chamber 4 opened inside the cooling net 32, and the interior of the inner chamber 4 is filled with ice bags 41, the overall temperature of the cooling net 32 ​​can be reduced. When the cooling water passes through the cooling net 32, the heat of the cooling water itself can be further absorbed, thereby improving the cooling of the cooling water.

[0033] Since the water tank 21 is movably mounted on the surface of the lower mold 12, in order to improve the connection sealing between the water tank 21 and the lower mold 12 and reduce the situation of cooling water flowing out, Figure 1-Figure 4 As shown, a sealing gasket 5 is fixedly connected to one side of the water tank 21 close to the lower mold 12, and the sealing gasket 5 is made of elastic material.

[0034] The improvement lies in that: by using a sealing gasket 5 fixedly connected to the side of the water tank 21 close to the surface of the lower module 12, the connection gap between the water tank 21 and the surface of the lower module 12 can be filled, thereby improving the tightness of the connection between the water tank 21 and the lower module 12 and reducing the leakage of cooling water.

[0035] In summary, the working principle of this scheme is as follows: first, the upper mold 11, the lower mold 12 and the movable column 13 are used to close the upper mold 11 and the lower mold 12, so that the silicone rubber mold is formed inside the molding chamber 14. After the water tank 21 is installed on the surface of the lower mold 12, the cooling water is poured into the inside of the water tank 21 through the cooling water inlet and outlet. The water tank 21 is connected with the flow groove 22 so that the cooling water can flow into the inside of the flow groove 22. The sealing gasket 5 fixedly connected to the side of the water tank 21 close to the surface of the lower mold 12 can be used to fill the connection gap between the water tank 21 and the surface of the lower mold 12, thereby improving the tightness of the connection between the water tank 21 and the lower mold 12 and reducing the leakage of cooling water. The pump body 23 is used to facilitate the replacement of the cooling water inside the flow groove 22 with the cooling water inside the water tank 21, thereby improving the fluidity of the cooling water. The flow groove 22 surrounds the periphery of the molding chamber 14 on three sides, effectively improving the cooling effect of the molding chamber 14.

[0036] By using two mounting plates 31 arranged on the inner wall of the water tank 21, the cooling net 32 ​​can be snapped into the mounting groove 33 opened on the surface of the mounting plate 31. When the cooling water inside the circulation groove 22 flows to the inside of the water tank 21 through the pump body 23, the cooling water can pass through the surface of the aluminum cooling net 32. When the cooling water enters the inside of the circulation groove 22 again, its own heat can be absorbed by the cooling net 32, thereby improving the demolding efficiency of the mold inside the molding bin 14. By using the inner bin 4 opened inside the cooling net 32, and the interior of the inner bin 4 is filled with ice bags 41, the overall temperature of the cooling net 32 ​​can be reduced. When the cooling water passes through the cooling net 32, the heat of the cooling water itself can be further absorbed, thereby improving the cooling of the cooling water.
