The slide rail is installed on the workbench, the injection molding machine is installed on the slide rail, and several die pressing machines are arranged along the length direction of the slide rail and are located on one side of the slide rail. The injection molding machine includes a fixed frame, a glue storage tank, a piston, a third cylinder, a fourth cylinder, and an injection head. A molding mold is arranged in the die pressing machine, and a molding cavity is arranged in the molding mold. The molding cavity includes a molding channel and several nose pad fixing grooves communicated with the molding channel. One end of the molding channel has an injection port communicated with the outside and corresponding to the injection nozzle. Compared with the prior art, the injection molding machine in the present invention can work continuously, has high production efficiency, and reduces production costs. However, when silicone is molded by a mold, it is usually necessary to cool the mold so that the silicone can be quickly cooled and molded. The common cooling method is mostly to cool by water cooling, using cold water to absorb and dissipate the heat of the mold to achieve the purpose of cooling. And a single cooling method makes it difficult to quickly dissipate heat and is not conducive to the quick cooling and molding of silicone.

[0004] Therefore, in order to solve such problems, we propose a cooling structure of a silicone molding machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cooling structure of a silicone molding machine, aiming to solve the problem in the above background art that the existing silicone molding machine mostly cools by water cooling, using cold water to absorb and dissipate the heat of the mold to achieve the purpose of cooling. And a single cooling method makes it difficult to quickly dissipate heat and is not conducive to the quick cooling and molding of silicone.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A cooling structure of a silicone molding machine includes a mold and a molding groove opened inside the mold. Support plates are arranged at both ends of the bottom of the mold. A cooling channel and an air-cooling component are arranged inside the mold outside the molding groove, and a water-cooling component is arranged inside the cooling channel;

[0024] Refer toFigures 1-5 , an embodiment provided by the present utility model: a cooling structure of a silicone molding machine, including a mold 1 and a molding groove 11 opened inside the mold 1. At both ends of the bottom of the mold 1, there are support plates 2. The support plates 2 are L-shaped and symmetrically arranged in two. Inside the mold 1 outside the molding groove 11, there is a cooling channel 3. The cooling channel 3 is serpentinely opened around and at the bottom of the molding groove 11. Inside the cooling channel 3, there is a water cooling component 4. Through the water cooling component 4, coolant is conveyed to the cooling channel 3 around the molding groove 11, so that the silicone product inside the molding groove 11 is quickly cooled and formed;

[0025] The water cooling component 4 includes a condensation water tank 41 arranged between the support plates 2. The condensation water tank 41 is movably arranged below the mold 1. At one end of the condensation water tank 41, there is an infusion pipe 42. The lower end of the infusion pipe 42 communicates with the inside of the condensation water tank 41. The upper end of the infusion pipe 42 penetrates the mold 1 and extends into the cooling channel 3. On the infusion pipe 42, there is a water pump 43. One end of the infusion pipe 42 located inside the cooling channel 3 is connected to a shunt pipe 44. On the shunt pipe 44, there are three cooling elbows 45 respectively. The three cooling elbows 45 are respectively arranged at the bottom and around the molding groove 11. The cooling elbows 45 are laid inside the cooling channel 3. One end of the cooling elbow 45 away from the shunt pipe 44 is connected to a confluence pipe 46. The confluence pipe 46 is arranged inside the mold 1 opposite to the shunt pipe 44. At the bottom of the confluence pipe 46, there is a liquid outlet pipe 47. The lower end of the liquid outlet pipe 47 penetrates the mold 1 and extends into the inside of the condensation water tank 41. Outside the liquid outlet pipe 47, there is a circulation pump 48. Through the water pump 43, the coolant in the condensation water tank 41 is pumped into the infusion pipe 42. The circulation pump 48 is turned on. The coolant flows through the shunt pipe 44 to the three cooling elbows 45 in different directions. The coolant in the cooling elbows 45 absorbs the heat transferred from the molding groove 11. Finally, the coolant that has absorbed the heat converges in the confluence pipe 46 and flows into the condensation water tank 41 through the liquid outlet pipe 47 for cooling, realizing the cooling of the silicone product inside the mold 1.

[0026] The air-cooling component 5 includes a ventilation cavity 51 disposed inside the mold 1 outside the cooling channel 3. The ventilation cavity 51 is respectively disposed around and at the bottom of the molding groove 11, and the respective ventilation cavities 51 communicate with each other. One end of the ventilation cavity 51 is provided with an air inlet 52, and a cold air conveying device can be connected to the air inlet 52. The end of the ventilation cavity 51 away from the air inlet 52 is provided with an air outlet 53, and the cold air that has absorbed heat is discharged through the air outlet 53. A heat dissipation groove 54 is formed on the side of the ventilation cavity 51 close to the molding groove 11. The inside of the heat dissipation groove 54 communicates with the inside of the ventilation cavity 51. The end of the heat dissipation groove 54 away from the ventilation cavity 51 extends to the outside of the molding groove 11. The heat dissipation groove 54 is disposed between the cooling channels 3. The molding groove 11 transfers heat to the heat dissipation groove 54. By connecting a cold air conveying device to the air inlet 52, cold air is conveyed into the interior of the ventilation cavity 51.

[0027] A dovetail chute 6 is formed at the top of the bottom plate of the support plate 2. A dovetail block 7 is disposed at the bottom of the condensation water tank 41. The dovetail block 7 is engaged with the dovetail chute 6. By inserting the dovetail block 7 into the dovetail chute 6 and sliding, the condensation water tank 41 is fixed below the mold 1.

[0028] An anti-slip pad 61 is attached to the inner side wall of the dovetail chute 6 to increase friction and prevent the dovetail block 7 from sliding randomly in the dovetail chute 6, avoiding the separation of the condensation water tank 41 from the support plate 2.

[0029] A liquid replenishing pipe 411 is disposed in the middle of the top of the condensation water tank 41. Coolant is replenished into the condensation water tank 41 through the liquid replenishing pipe 411.

The circulation pump 48 is turned on, and the coolant flows through the shunt pipe 44 to the cooling elbows 45 in three different directions. The coolant in the cooling elbows 45 absorbs the heat transferred from the molding groove 11. Finally, the coolant that has absorbed heat converges in the confluence pipe 46 and flows into the condensation water tank 41 through the liquid outlet pipe 47 for cooling and circulating heat dissipation. By connecting a cold air conveying device to the air inlet 52, cold air is conveyed into the interior of the ventilation cavity 51. The cold air blows through the ventilation cavity 51 towards the heat dissipation groove 54 to absorb heat, and then is discharged through the air outlet 53, realizing the cooling of the silicone product inside the mold 1.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
