The specific contents are as follows:

[0019] 1. Through the movement of the screw and the first side plate in coordination with the second side plate, the bottom plate, the first side plate and the second side plate can be quickly assembled to form a complete mold cavity, thereby facilitating the pouring of concrete to form a complete prefabricated part model;

[0020] Furthermore, the rotation of the toothed disc drives the first gear to rotate, and the rotation of the first gear drives the screw to rotate, and the rotation of the screw drives the first side plate and the second side plate around to move synchronously, so as to quickly close and form a mold cavity, and after the first side plate and the second side plate are closed, the fillet strip will be engaged with the embedding groove, so as to improve the integrity of the connection between the first side plate and the second side plate;
