Abstract
An apparatus (10) for molding metallic articles such as wheel weights (11). Opposed mold sections (108, 109) are carried on support plates (41, 42) that are movable within a stanchion (40) by virtue of an actuating means (45). A feed mechanism (115) delivers mounting clips (18) to one of the mold sections (109), and an escapement means (135) assures that only one clip (18) is delivered at a time. The actuating mechanism (45) sequentially closes the mold sections (108, 109) to form a cavity (100) therebetween, moves the closed mold sections (108, 109) into engagement with an injection tube (79) which mates with a sprue hole (111). The injection tube (79) also presents a positioning lug (180) accurately to rotate the clip (18) to its desired disposition. The injection tube displaces a plunger piston (70) in response to continued movement of the mold sections against the injection tube (79) by the actuating means (45 ) to pump molten metal (74) from a reservoir (75) through the injection tube (79) and into the mold cavity (100). The actuating means (45) cyclically open the mold sections (108, 109) so that an ejection means (184) on the same barrel (122) that presents the annular shoulder (121) which served as a stop to locate the clip (18) along the lower mold section (109) when it arrived from the feed mechanism (115) can remove any sprue and eject the wheel weight (11) from the mold section (109) and out through a funnel hopper (165).
