Mould device for an injection moulding machine for producing information medium discs using a female mould

摘要

The fixed part (2b) of the two-part mould is penetrated by a guide cylinder (3) onto which the carrier sleeve (13) of the female mould disc (14) can be pushed. On the guide cylinder (3) there is also seated a sliding sleeve (5) which can be moved back and forth by drive means (6) and is provided with radially resilient coupling arms (8). When the sliding sleeve (5) is in a front end position, the driver heads (8a) of the coupling arms (8) are out of engagement with a coupling collar (12) of the carrier sleeve (13); the latter can thus be pushed onto or removed from the guide cylinder without hindrance. When the sliding sleeve (5) is pulled back, the driving heads (8a) engage behind the coupling collar (12) and pull the carrier sleeve (13) and female mould disc (14) into their working position. When the sliding sleeve (5) is advanced, it pushes the carrier sleeve (13) back into the removal position, the coupling is forcibly disengaged, and the carrier sleeve (13) with the female mould disc (14) can be removed. The device serves for the production of CDs.
