The middle part of the right end of the forward and reverse screw rod 7 is fixedly connected with an adjusting crank 8. The left and right parts of the outer surfaces of the forward and reverse screw rods 7 are both threadedly connected with a fixing frame 9. A mold body 10 is clamped between the two fixing frames 9, and a prefabricated part body 11 is made of concrete in the mold body 10.

[0023] In this embodiment, the fixed frame 9 includes an adjusting frame 12, the front and rear ends of the adjusting frame 12 are fixedly connected with a bracket 13, the middle part of the right end and the lower part of the right end of the adjusting frame 12 are fixedly connected with a limiting rod 14, and the right ends of the two limiting rods 14 are interlaced and movably connected with the right frame wall of the demoulding support frame 1, and a threaded hole 15 is opened on the upper part of the right end of the adjusting frame 12; the adjusting frame 12 is set to a W-shaped structure, so that the adjusting frame 12 has a reinforcing effect on the bracket 13, which can improve the firmness of the adjusting frame 12 and the bracket 13, and the bracket 13 is set to an L-shaped structure, so that the bracket 13 can support the mold body 10 while firmly clamping the mold body 10, and the distance between the left end face of the bracket 13 and the right frame wall is less than the thickness of the mold body 10, so that the bracket 13 does not contact the preform body 11 and does not affect the demoulding of the preform body 11.
