ABSTRACT:
An injection molding die for an injection molding machine is capable of injecting a plurality of plastic components or one plastic component and a gas or liquid, selectively or simultaneously. The molding die includes a die base with a die channel which slidably receives a sleeve element. An injection aperture in the die channel can be closed or opened by the sleeve element. A pin channel in the sleeve element receives a closing pin which is fixed to the die base. A passage opening in the sleeve element can be closed or opened by relative movement between the sleeve element and the closing pin. A lever arrangement extends laterally from the sleeve element for moving the sleeve element in the die channel.
