(57) Abstract :
The invention relates to an apparatus and method for the production of bimaterial hollow bodies by means of injection overmoulding.
The apparatus includes: a number n of base moulding cavities (1) or groups of base moulding cavities (1) inserted between a number
n+1 of overmoulding cavities (2a. 2b) or groups of overmoulding cavities (2a, 2b) or vice versa; and a number 2n of cores (3) or
groups of cores (3) which are fixed to a core holder plate (32) that is mounted such that it can move in a transverse direction (DT) on a
base plate (30) that is actuated to move in a longitudinal direction (DL) in order alternately to insert each core (3) into one of the base
moulding cavities (1). so as to mould a first layer, and into one of the overmoulding cavities (2a, 2b). so as to ovennould a second
layer. The apparatus also includes ejecting means for ejecting the finished bimaterial hollow bodies (P) and valve means (21) for
alternately distributing the moulding material to one or the other of the outer cavities.
