THERMOSETTING RESIN MOLDING METHOD

摘要

PURPOSE:To shorten the molding and reduce the molding cycle by making differences between a plurality of cavities and thus controlling thermosetting resin after a lapse of a predetermined time to be uniform in its curing. CONSTITUTION:Respective four holes 38 for a heater are formed on a stationary side mold 30 and a movable side mold 45, a high temperature heater 47 and a high temperature thermocouple are disposed in two inside holes 38 and a high temperature heater 48 and a heating thermocouple are disposed in two outside holes 38. An area in the proximity of the central part of a mold 2 is made into a high temperature area A to be heated by the high temperature heater 47 for heating the inner cavity 1a at high temperature. Also, areas in the vicinity of both ends of the mold 2 are made into low temperature areas B lower than the high temperature area A, and are formed along the heater 48, then outer cavities 1b in the low temperature areas B are heated by a temperature lower than the inner cavity 1a. In this way, the curing time in a part of being late in its curing time is hastened so as to render the curing uniform.
