Adjustable manufacturing template for precast concrete component

The invention relates to an adjustable manufacturing formwork of a concrete prefabricated part, and belongs to the technical field of prefabricated part formworks for buildings, the adjustable manufacturing formwork comprises a bottom formwork, two moving plates are arranged on the bottom formwork, the length direction of the moving plates is the same as that of the bottom formwork, the moving plates are connected with side formworks, and the side formworks are arranged on the bottom formwork. A pouring space is formed between the two side formworks, the side formworks are obliquely arranged towards the outer portion of the pouring space or are arranged perpendicular to the bottom formwork, first dovetail blocks are arranged at the two ends of the bottom of the movable plate in the length direction, and first dovetail grooves matched with the first dovetail blocks are formed in the bottom formwork. And a driving mechanism for driving the movable plate to move along the length direction of the bottom template
