MUD ® Quick-Change Options features and applications
The wide range of available options enhance the exceptional design versatility of the Master Unit Die Concept. These options can also increase the cost saving benefits and time saving features of this superior approach to injection molding. The basic design of MUD® Quick-Change frames and companion insert molds adds to these advantages. The open configuration of the frame permits installa- tion of water lines or hydraulic cylinders in the insert mold. The smaller size and lighter weight of insert molds simplifies machining. These design features also simplify routine maintenance. Frame options include interlocking ejector rails to lock the insert mold’s ejector system to the master ejector plate. The master ejector plate can be spring loaded for returning the insert mold’s ejector system. It can also be tied to the machine’s hydraulic knockout system for stroking the insert mold’s ejector assembly. Other frame options include water lines in the center bar or other locations, insulation boards, runner shutoffs and hot tip sprue bushings. Frame spacer bars to accommodate shorter, more economical companion insert molds are available for frames designed for longer sizes. Additional retainer slots and a spacer plate in the frame’s cavity half allow the frame to accept insert molds with different thicknesses. Either option results in greater production and scheduling flexibility. MUD® Quick-Change U frames can be adapted to multiple insert molding similar to H frames with the addition of an optional removable center runner bar and a master ejector plate. This allows simultaneous molding with two smaller insert molds. Design options for insert molds include spring loading, early return, unscrewing mechanisms, hot runner molding and machining for cam slides. Insert molds can be ordered with interlocking ejector plates for stroking action when used with frames having an interlocking ejector system.
Insert molds are available with a complete ejector system including return pins and pillar posts. Other options include stripper plates, sleeve ejection and three-plate construction for a pinpoint gating system. Machining is also available for heater cartridge holes, water lines, rough or finished pockets, taper locks and other special applications. The addition of a hot manifold brings all of the advantages of the Quick-Change Concept to hot runner molding. Since both the frame and the hot runner system remain in the molding machine, only the insert molds are changed for new parts. This means faster changeovers, lower tooling costs and greater scheduling flexibility for hot runner systems, too. MUD® Quick-Change tooling combined with the options and accessories included in the following pages offer mold makers, design engineers and manufacturing engineers the most efficient system in the plastics industry.
