Abstract
A cut-off process for an injection molding machine for forming two-layer, directly laminated footwear soles and includes a pressure transmission pin which is guided in a passageway constructed as a through-hole between the mold cavity and the outer surface of the mold. The pressure transmission pin is preloaded by a spring in the direction of the mold cavity so that it can be depressed or actuated under injection pressure. When the injection pressure is relieved and the molded piece shrinks, the pressure transmission pin will be moved back by the spring to its initial position, thereby releasing a switch for a new switching operation for the next, second, injecting operation.
