Abstract:
A molding method for forming a plastic part with a mold including first and second mold portions movable towards and away from each other in a mold movement direction and a modular side-action cam mechanism, the molding method comprising:attaching the modular cam mechanism to one of the first and second mold portions;providing a driver actuator of the modular cam mechanism having an engagement surface and a cam surface;positioning the driver actuator engagement surface in a first extended position by biasing the driver actuator towards the other mold portion when the mold portions are open for movement in the mold movement direction towards the other mold portion;moving the mold portions together to engage the driver actuator engagement surface with the other mold portion; anddriving a slide device having a cam surface for cooperating with the cam surface on the driver actuator and carrying a side coring element as an incident of the engagement of the actuator engagement surface and other mold portion depressing the driver actuator against the bias and the cam surfaces cooperating to cause the slide device to move transversely of the direction of mold movement toward the mold cavity to project the coring element into a mold cavity of the closed mold portions.
