ABSTRACT:
A quick-switch mold set is depicted wherein the interchangeable mold plate is carried by a T-plate slideable in grooves provided by a top clamping plate which is secured to the upper platen of the molding machine. A lower interchangeable mold plate is carried by an intermediate T-plate slideable in grooves provided in a bottom clamp housing. Removable and rotatable clamps are secured to the top clamping plate and other clamps to the bottom clamp housing. The clamps are disc-like, having two flats providing reduced portions that are positioned in way of a T-plate and mold plate during removal and interchange. The clamps are repositioned and tightened to provide the desired securement and retention of the mold plate and T-plate.
