[0022] In an optional embodiment: a first motor 11 is fixedly installed on one side of the base 2, a rotating rod 12 is rotatably connected inside the base 2, an output end of the first motor 11 is fixedly connected to the rotating rod 12, a driving bevel gear 13 is fixedly connected to the surface of the rotating rod 12, the driving bevel gear 13 is meshingly connected to a driven bevel gear 14, and the middle part of the driven bevel gear 14 is fixedly connected to the bottom of the screw rod 5.

[0023] It should be noted that after the concrete is cast, the first motor 11 can be started so that the first motor 11 drives the rotating rod 12 to rotate, thereby driving the active bevel gear 13 to rotate, and then driving the driven bevel gear 14 to rotate, thereby achieving the effect of driving the screw 5 to rotate. At this time, the sliding plate 7 slides upward under the action of the screw 5 and the sliding rod 6, thereby driving the upper mold 8 to move upward under the action of the sliding plates 7 on both sides, so that the top of the concrete prefabricated part inside the lower mold 3 is exposed, which is convenient for observing the concrete molding effect and also convenient for removing the prefabricated parts.

[0024] In an optional embodiment: a bidirectional screw rod 15 is rotatably connected inside the base 2, a second motor 16 is fixedly installed inside the base 2, an output end of the second motor 16 is fixedly connected to the bidirectional screw rod 15, sliding seats 17 are threadedly connected on both sides of the bidirectional screw rod 15, a first rotating seat 18 is fixedly connected to the top of the sliding seat 17, a support rod 19 is rotatably connected to the middle of the first rotating seat 18, a second rotating seat 20 is fixedly connected to the bottom of the push plate 9, and the top of the support rod 19 is rotatably connected to the second rotating seat 20.

[0029] It should be noted that when the vibration motor 31 is started, the vibration seat 30 is driven to vibrate. At this time, the second spring seat 29, the spring 28 and the first spring seat 27 at the four corners of the bottom of the vibration seat 30 are repeatedly squeezed under the action of vibration, thereby achieving the effect of driving the upper half of the entire device to shake, and then having an effect similar to vibration on the concrete inside the lower mold 3 and the upper mold 8, thereby improving the quality of the prefabricated parts.
