Description

Technical Field

[0001] This utility model relates to the field of rubber sealing strip processing technology, specifically a rapid cooling mold for processing rubber sealing strips. Background Technology

[0002] Rubber sealing strip mold cooling refers to the process of setting up a cooling system inside the rubber mold and using the circulation of coolant to control the mold temperature, thereby ensuring the fluidity of the rubber material and accelerating the cooling and hardening of the product. Therefore, corresponding cooling operations are required when molding rubber sealing strips.

[0003] According to the announcement number CN217621923U, a rapid cooling mold for processing automotive rubber sealing strips is disclosed, including a mold body. The upper end of the mold body is provided with a mold groove. A fixing layer is provided on the outside of the cooling part inside the mold body. A silicone plate is fixedly connected to the outside of the fixing layer. Copper tubes are provided at equal intervals on the inner side of the silicone plate. Copper sheets are provided on the inner side of the copper tubes.

[0004] Although the rapid cooling mold for processing automotive rubber sealing strips can expand the heat conduction surface by using copper sheets on the inner wall of the copper pipe, allowing the cooling water to carry away more heat after entering the copper pipe, the cooling area of ​​the coolant inside the copper pipe is relatively small, and its cooling effect is ultimately limited. In order to improve the cooling effect on the mold, the device needs to be improved. Utility Model Content

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Combination Figures 2 to 5 A rapid cooling mold for processing rubber sealing strips includes a cooling box 1, a lifting mechanism 2 on the top of the cooling box 1, and a constant temperature mechanism 3 fixedly connected to the top of the cooling box 1.

[0029] The lifting mechanism 2 includes a drive motor 21, which is located at the top of the cooling box 1. A lead screw 22 is fixedly connected to the top of the drive motor 21. A top frame 23 is rotatably connected to the top of the lead screw 22. A threaded frame 24 is provided on the surface of the lead screw 22. A movable frame 25 is fixedly connected inside the threaded frame 24. An electric push rod 26 is fixedly connected inside the movable frame 25. A mold box 27 is fixedly connected to the bottom of the electric push rod 26. A telescopic cover 28 is fixedly connected between the top of the mold box 27 and the bottom of the movable frame 25. A through hole is opened inside the movable frame 25. The surface of the electric push rod 26 passes through the through hole inside the movable frame 25.

[0030] Furthermore, threaded holes are respectively opened inside the four ends of the movable frame 25, and there are four lead screws 22. The surfaces of the four lead screws 22 are respectively threaded to the inside of the threaded holes. The drive motor 21 drives the lead screws 22 to rotate and thus drives the threaded frame 24 to move up and down. This causes the mold box 27 to move downward into the cooling box 1. The coolant in the cooling box 1 can cool the workpiece inside the mold box 27. During this process, the electric push rod 26 can drive the mold box 27 deeper into the cooling box 1, thereby enhancing the rapid cooling operation of the workpiece inside the mold box 27, increasing the effective area of ​​the coolant, and improving the cooling effect on the mold.

[0031] Example 2

[0032] See Figure 1-5 Based on Embodiment 1, the constant temperature mechanism 3 further includes a support frame 31, which is fixedly connected to the top of the cooling box 1. Support plates 32 are fixedly connected to the left and right ends of the top of the support frame 31, and a motor rod 33 is fixedly connected to one side of the support plate 32. A gear 34 is fixedly connected to one end of the surface of the motor rod 33. A heat insulation cavity is opened inside the cooling box 1, and a heat insulation plate 39 is fixedly connected inside the heat insulation cavity. Support rods 35 are rotatably connected to the left and right sides inside the cooling box 1, and a support ring 36 is fixedly connected to the surface of the support rod 35. A toothed ring 38 is fixedly connected to the surface of the support ring 36. A stirring blade 37 is rotatably connected to one side of the support ring 36. The surface of the gear 34 meshes with the surface of the toothed ring 38. The bottom end of the support frame 31 is fixedly connected to the top of the drive motor 21. A through hole is opened at the bottom end of the support frame 31, and the lower surface of the lead screw 22 passes through the through hole opened at the bottom end of the support frame 31. A through hole is opened inside the support plate 32, and the surface of the motor rod 33 passes through the through hole opened inside the support plate 32.

[0033] Furthermore, there are two sets of stirring blades 37, which are respectively set at both ends inside the cooling box 1. The support ring 36 and the stirring blades 37 rotate and stir the water inside the cooling box 1. This allows the hot water at the top to be mixed and exchanged with the cold water at the bottom, and the cold water at the bottom to be sent to the top to cool the mold box 27, thereby improving the utilization efficiency of the coolant inside the cooling box 1.

[0034] In actual operation, when this device is used to cool the mold, coolant is placed inside the cooling box 1, and there are water inlet pipes and water outlet pipes on the left and right sides of the cooling box 1 respectively. Cold water is injected into the water inlet pipes. The molded mold is placed inside the mold box 27. At this time, the drive motor 21 drives the lead screw 22 to rotate and then drives the threaded frame 24 to move up and down, thereby driving the mold box 27 to move down into the cooling box 1. The coolant in the cooling box 1 can cool the workpiece inside the mold box 27. During this process, the electric push rod 26 can drive the mold box 27 to move deeper into the cooling box 1, thereby enhancing the rapid cooling operation of the workpiece inside the mold box 27.

[0035] In addition, when the workpiece is cooled, the motor rod 33 drives the gear 34 and the gear ring 38 to rotate, which in turn drives the support ring 36 and the stirring blade 37 to rotate, and stirs the water inside the cooling box 1. This allows the hot water at the top to be mixed and exchanged with the cold water at the bottom, and the cold water at the bottom to be sent to the top to cool the mold box 27, thereby improving the utilization efficiency of the coolant inside the cooling box 1.
