Abstract:
A method of disassembling an injection molding system including a mold, a clamp plate coupled to the mold, a manifold having at least one injection nozzle coupled thereto, the manifold being seated between the mold and the clamp plate, and a valve pin actuator mounted in the clamp plate and including a piston slidably and sealingly mounted therein having a valve pin coupled thereto so that movement of the piston causes axial movement of the valve pin, wherein the valve pin extends from the clamp plate and into the manifold, the method comprising the steps of:(A) decoupling the valve pin from the piston while the clamp plate remains coupled to the mold, the valve pin actuator remains mounted in the clamp plate and the piston remains sealingly mounted within the valve pin actuator; and (B) decoupling the clamp plate and the valve pin actuator; including the piston, from the mold while the valve pin remains extended into the manifold.
