Top Clamp Plate

This is the top plate of the mold when it is in the storage position out of the press. When it is in the press this plate will rest against the stationary plate. It has clamp slots milled into it or mounting bolt holes to retain the mold in the press during opening. The top clamp plate also retains the cavity blocks, locating ring, sprue bushing, and leader pins. It will typically also have water lines drilled into it and have the electrical box mounted to it if the mold has a hot runner system.
