APPARATUS AND METHOD FOR THE PRODUCTION OF BI-MATERIAL HOLLOW BODIES BY MEANS OF INJECTION OVERMOLDING |
摘要 |
An apparatus and method for the production of bi-material hollow bodies by injection overmolding. The apparatus includes: n base molding cavities or groups of base molding cavities inserted between n+1 overmolding cavities or groups of overmolding cavities or vice versa; and 2n cores or groups of cores which are fixed to a core holder plate mounted such that it can move in a transverse direction on a base plate that is actuated to move in a longitudinal direction in order alternately to insert each core into one of the base molding cavities, so as to mold a first layer, and into one of the overmolding cavities, so as to overmold a second layer. The apparatus also includes an ejecting device for ejecting the finished bi-material hollow bodies and a valve for alternately distributing the molding material to one or the other of the outer cavities. |
