Description

Technical Field

[0001] This utility model relates to the field of silicone rubber product processing technology, specifically a molding device for processing silicone rubber products. Background Technology

[0002] When molding silicone rubber polymer materials, the silicone rubber polymer materials need to be heated and then extruded into shape by extrusion blocks inside the mold.

[0003] A search revealed a Chinese patent with publication number CN212123941 U, which discloses a molding device for processing silicone rubber products. The key technical point of this device is that it solves the problem that after extruding silicone rubber polymer materials, the cooling rate is slow and the temperature is high, making it inconvenient for the operator to handle the material.

[0004] However, in the above-mentioned solutions, it was found that since most silicone rubber products are embedded in the mold core after molding, there is a lack of a structure to eject the molded silicone rubber products, making it inconvenient for operators to remove the molded silicone rubber products and reducing production efficiency. In order to solve the problem of the lack of a structure to eject the molded silicone rubber products in the prior art, which makes it inconvenient for operators to remove the molded silicone rubber products and reduces production efficiency, this application proposes to set up components such as a threaded rod and a sliding column. Through the connection of gear one, gear belt and gear two, the threaded rod rotates, which in turn allows the sliding column to drive the ejector block to eject the molded silicone rubber products. This achieves the effect of automatically demolding the molded silicone rubber products from the mold core, improving production efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

The output shaft of the motor is fixedly connected to a gear, the outer surface of the gear is meshed with a toothed belt, the inner wall of the toothed belt is meshed with a gear, the inner wall of the gear is fixedly connected to a threaded rod, the outer surface of the threaded rod is threadedly connected to a sliding column, the top of the sliding column is fixedly connected to a top block, the outer surface of the sliding column is slidably connected to a mold core, the bottom surface of the mold core is fixedly connected to a fixed rod arranged at equal intervals, the bottom end of each fixed rod is fixedly connected to the inner bottom wall of the mounting base, and the bottom end of the threaded rod is rotatably connected to the inner bottom wall of the mounting base.

[0007] Furthermore, a mounting bracket is fixedly connected to the inner bottom wall of the mounting base, and the bottom surface of the mounting bracket is fixedly connected to the upper surface of the motor.

[0008] Furthermore, a mounting frame is fixedly connected to the bottom surface of the mounting base, and two telescopic rods are fixedly installed on the inner wall of the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as gear one, toothed belt, gear two, threaded rod one, sliding column, and top block, allows gear one to rotate via motor one after the molding process is completed. The connection between gear one, toothed belt, and gear two enables gear two to rotate, which in turn drives threaded rod one to rotate. The connection between threaded rod one and sliding column allows sliding column to rise and fall within the mold core, thereby enabling the top block to rise and fall, ejecting the molded silicone rubber product. This facilitates the automatic demolding of silicone rubber products from the mold core, improving production efficiency.

This utility model, by setting up components such as a threaded rod, a threaded block, a housing, a nozzle, a liquid inlet pipe, and a mounting rod, allows the upper mold to reset after the molding process is completed. At this time, the threaded rod is rotated by the motor, which in turn allows the threaded block to move. The sliding groove on the inner wall of the mounting rod limits the housing, allowing the threaded block to move the housing. The housing then moves the nozzles on both the upper and lower sides, and liquid nitrogen is supplied to the housing through the liquid inlet pipe. The liquid nitrogen is then sprayed out through the nozzles onto the surfaces of the mold core and the upper mold, achieving rapid cooling of the mold core and the upper mold.

[0029] In this embodiment, a support base 15 is fixedly connected to the right side of the mounting frame 12.

The rotation effect of the second threaded rod 17 can be achieved through the second motor 16.

[0030] like Figure 4 As shown, a threaded block 18 is threadedly connected to the outer surface of the threaded rod 17. The threaded block 18 is installed on the outer surface of the threaded rod 17, forming a threaded connection. The rotation of the threaded rod 17 allows the threaded block 18 to move laterally left and right. A housing 19 is fixedly connected to the outer surface of the threaded block 18. The housing 19 is installed on the outer surface of the threaded block 18, forming a fixed connection. The movement of the threaded block 18 allows the housing 19 to move synchronously.

[0031] In a preferred embodiment, nozzles 20 arranged at equal intervals are fixedly installed on the upper and bottom surfaces of the housing 19. The nozzles 20 are installed on the upper and bottom surfaces of the housing 19 to achieve the installation of the nozzles 20. Liquid nitrogen can be sprayed out through the nozzles 20 and sprayed on the side of the upper mold 14 and the mold core 8 that are close to each other, so that the upper mold 14 and the mold core 8 can be cooled quickly.

The contour of the sliding groove 23 can achieve the limiting effect of the housing 19.

[0033] The implementation principle is as follows: The extension of the telescopic rod 13 causes the upper mold 14 to descend, engaging with the mold core 8 to perform molding. After molding, the telescopic rod 13 resets the upper mold 14. At this time, the motor 16 drives the threaded rod 17 to rotate, which in turn moves the threaded block 18. The threaded block 18 then moves the housing 19, which in turn moves the nozzles 20 on both the upper and lower surfaces. Liquid nitrogen is then supplied to the housing 19 through the inlet pipe 21, and the liquid nitrogen is then sprayed out through the nozzles 20. Rapid cooling of the mold core 8 and upper mold 14 is achieved on their surfaces. At this time, motor 1 drives gear 2 to rotate. Through the connection between gear 2, gear belt 3 and gear 4, gear 4 can rotate, which in turn drives threaded rod 5 to rotate. Through threaded rod 5, sliding column 6 can rise and fall on the inner wall of mold core 8, which in turn causes top block 7 to rise and fall, ejecting the molded silicone rubber product. This makes it easy for the device to automatically demold the silicone rubber product from mold core 8, improving production efficiency.
