This utility model relates to the field of cold heading machine mold replacement, and discloses a multi-station quick-change mold mechanism for a bolt cold heading machine. It includes a machine body, a rear platen seat disposed inside the machine body, and a mold mounting seat disposed at the top of the rear platen seat. An installation assembly is provided between the rear platen seat and the mold mounting seat. The installation assembly includes a mounting plate fixedly connected to the left side of the mold mounting seat near its bottom. A connecting plate is fixedly connected to the left side of the mounting plate. Multiple sets of locking blocks are evenly distributed and fixedly connected to the bottom of the mounting plate. The top left side of the rear platen seat has evenly distributed slots corresponding to the multiple sets of locking blocks. In this utility model, by quickly releasing the limiting positions of the mounting plate and the connecting plate, the mounting plate and the rear platen seat can be quickly and securely connected for installation or removal. The operation is simple and convenient, significantly shortening mold replacement time, effectively reducing downtime of the cold heading machine, allowing the equipment to be put into production more efficiently, and improving overall production efficiency.

The utility model relates to bridge engineering construction technical field especially relates to a collapsible prefabricated small box girder quick -detachable form, include: bottom form, side form, inner form and end form, end form is used to close the end of box girder, and side form is located bottom form both sides. Inner form is composed of left form and right form that are left -right symmetrical, and left form is composed of hinged left upper inner form and left lower inner form, and right form is composed of hinged right upper inner form and right lower inner form. The adjusting support mechanism for supporting and locking the unfolded angle is equipped on left form and right form. The connecting mechanism that can be quickly assembled and disassembled is equipped between the butt -joint edge of left upper inner form and right upper inner form and between the butt -joint edge of left lower inner form and right lower inner form. The utility model discloses through the hinged folding and quick -detachable design of inner form, realized the early whole dismantling of inner form and fast turnover, has improved construction efficiency greatly and reduced form material backlog cost.
