Mold element retaining system and method

摘要

A mold element retaining system and method includes a spigot to be connected to a mold or to a machine platen and retained in place by a retaining means operable to engage and release the spigot. The retaining means is moved between a first configuration, wherein it engages the spigot and a second configuration wherein it releases the spigot by an actuator which, in a preferred embodiment, is a pneumatically operable piston.
