CA 2694093

A machine for compression molding plastic articles includes a turret (22) constructed for rotation around a vertical axis (26). A first array (28a or 28c) of compression molds and a second array (28b or 28d) of compression molds are mounted on the turret for movement through respective first and second mold paths (40, 42) as the turret rotates around the vertical turret axis. A first mold charge placement mechanism (38a) is disposed adjacent to the first path for placing mold charges into molds of the first array in sequence as the turret rotates. A second mold charge placement mechanism (38b) is disposed adjacent to the second path for placing mold charges into molds of the second array in sequence as the turret rotates and independently of the first mechanism. The first and second mold paths maybe spaced from each other radially of the turret axis and/or longitudinally of the turret axis.

L'invention concerne une machine pour mouler sous pression des articles en matière plastique comprenant une tourelle (22) construite pour tourner autour d'un axe vertical (26). Un premier réseau (28a ou 28c) de moules sous pression et un second réseau (28b ou 28d) de moules sous pression sont montés sur la tourelle pour se déplacer à travers des premier et second trajets de moule respectifs (40, 42) lorsque la tourelle tourne autour de l'axe vertical de tourelle. Un premier mécanisme de positionnement de charge de moulage (38a) est disposé de manière adjacente au premier trajet pour placer des charges de moulage dans des moules du premier réseau en séquence lorsque la tourelle tourne. Un second mécanisme de positionnement de charge de moulage (38b) est disposé adjacent au second trajet pour mettre des charges de moulage dans des moules du second réseau en séquence lorsque la tourelle tourne et indépendamment du premier mécanisme. Les premier et second trajets de moule peuvent être espacés l'un de l'autre radialement par rapport à l'axe de tourelle et/ou longitudinalement par rapport à l'axe de tourelle.
