Description

Technical Field

[0001] The utility model relates to the technical field of tooling equipment, in particular to a mold lifting and turning device. Background Art

[0002] The Resin Transfer Molding (RTM) process is a closed mold molding process, and its mold includes an upper mold and a lower mold. When producing composite materials, the upper mold needs to be flipped at least twice to close and demold the upper and lower molds. Before closing the mold, the layers are laid on the upper mold and simply fixed. When demolding, the upper mold is flipped so that the mold cavity faces upward to facilitate laying. The current mold flipping method is to use a sling to tie up the steel frame part of the upper mold, and then use a crane to lift the upper mold and flip it manually. The flipping method is relatively rough. When closing the mold, the layers or embedded parts are easy to fall off, disrupting the production rhythm. When opening the mold, it is easy to cause bumps and collisions on the mold surface, reducing the service life of the mold. Utility Model Content

In this embodiment, the second drive device 310 includes a motor 311, a first gear 312, a second gear 313, and a rotating shaft 314. The first gear 312 is fixedly connected to the output shaft of the motor 311, the second gear 313 meshes with the first gear 312, the second gear 313 is sleeved on the rotating shaft 314, and the second gear 313 is fixedly connected to the rotating shaft 314. The rotating shaft 314 is rotatably mounted on the second fixed plate 242 via a slew bearing. The end of the rotating shaft 314 facing away from the frame 100 is fixedly connected to the guide base 320. The motor 311 rotates, driving the first gear 312. The first gear 312, through the second gear 313, drives the rotating shaft 314. The rotating shaft 314 then drives the guide base 320, which in turn drives the cantilever 330. The first gear 312 is a small gear, and the second gear 313 is a large gear. The first gear 312 and the second gear 313 mesh together to transmit power. This arrangement converts high-speed, low-torque power into low-speed, high-torque output through a torque-increasing effect, enhancing the stability of the device.

[0028] The rotational mounting method of the rotating shaft 314 on the second fixed plate 242 is not limited herein; the rotating shaft 314 can be mounted on the second fixed plate 242 in any rotatable manner. In this embodiment, slewing bearings are provided at both ends of the rotating shaft 314, mounted on bearing blocks 315, enabling the rotational mounting of the rotating shaft 314 on the second fixed plate 242. The number of cantilevers 330 is not limited herein and can be adjusted according to actual needs. The type of motor 311 is not limited herein; the motor 311 can be a servo motor, a variable frequency motor, a stepper motor, or the like. Rotation of the output shaft of the motor 311 drives the first gear 312, which in turn drives the guide base 320 via the second gear 313. The guide base 320 drives the cantilever 330 fixed thereto, which in turn drives the mold 10 to rotate, thereby achieving flipping of the mold 10. To restore the mold 10, the output shaft of the motor 311 is rotated in the opposite direction to flip the mold 10 back to its original position.

[0029] See also Figure 2 and Figure 3 In one embodiment, a third chute 321 is provided on the side of the guide seat 320 facing the mold 10, through which the cantilever 330 slides. One end of the cantilever 330, which is fixedly connected to the guide seat 320, extends into the third chute 321. A protrusion is provided on the end of the cantilever 330 that extends into the guide seat 320. The protrusion stops at the edge of the third chute 321, preventing the cantilever 330 from falling off. In this embodiment, a first wedge block 331 is provided on the side of the cantilever 330 near the guide seat 320. A second wedge block 332 is provided between the first wedge block 331 and the guide seat 320, and is mated with the first wedge block 331. The second wedge block 332 is provided with a through hole, and the cantilever 330 is provided with a threaded hole. A bolt passes through the through hole in the second wedge block 332 and is threadedly connected to the threaded hole in the cantilever 330.

[0030] See also Figure 2In one embodiment, the flip unit 300 includes two cantilevers 330 that can slide along the third chute 321 to adjust the position of the two cantilevers 330 on the guide base 320 and the spacing between the two cantilevers 330 to accommodate molds 10 of varying sizes. To adjust the spacing between the two cantilevers 330, loosen the bolts to reduce the pressure of the second wedge block 332 on the first wedge block 331, and slide the cantilevers 330 along the third chute 321 to adjust the spacing between the two cantilevers 330. In this embodiment, one end of the cantilever 330, which is fixedly connected to the mold 10, is provided with a jaw 333 for securing the mold 10. Tightening the knob nut 334 secures the mold 10 to the cantilever 330, and loosening the knob nut 334 loosens the jaw 333 to separate the mold 10 from the cantilever 330. Specifically, the jaws 333 include a first jaw 3331 and a second jaw 3332. The first jaw 3331 is fixedly mounted on the cantilever 330, and the second jaw 3332 is rotatably mounted on the cantilever 330 via a pin. When the jaws 333 clamp the steel frame of the mold 10, the steel frame is placed between the first jaw 3331 and the second jaw 3332. The knob nut 334 is used to squeeze the first and second jaws 3331 and 3332, thereby fixing the steel frame between the first and second jaws 3331 and 3332.
