PURPOSE:To enable to perform a molding work without the movement of a mold, by bringing axis lines of a head and a pot into coincidence with each other through movement of a head of a plunger within a given range in a direction of a radius. CONSTITUTION:When a head 26 is positioned facing and opposite to an attaching axle 12 at a slight distance (e), and is supported to frame pieces 21a and 21b so that its axis line coincides with that of the attaching axle 12, it can freely move in a direction of a radius by a full distance (e) of a play. If an axis line of a pot 4 is slightly displaced from that of the head 26, the axis lines coincide with each other through movement of the head 26, the head 26 of a plunger engages the pot 4 in an appropriate condition, comeout is prevented from occurring at the head 26 of the plunger or the inner wall of the pot 4, and this allows to perform a smooth and reliable molding work. |
