Abstract
Wings are provided on mold components and linear ways are provided below these wings. A pad rides on each linear way below each wing. A force generator, such as a spring, is disposed between each wing and underlying pad. In this way the weight of the mold components is borne, at least in part, by the linear ways so that the weight on components that might otherwise sag is lessened.
Claims16
A mold assembly for use in a molding machine comprising:
- an ejector box having a plurality of guides, said ejector box defining at least one ejector box linear way;
- a cassette having at least one cassette plate extending within said ejector box and supported on said guides, each cassette plate for supporting a mold piece, each cassette plate having at least one cassette plate support member extending over one said ejector box linear way;
- at least one pad riding on each said ejector box linear way such that there is a pad below each cassette plate support member;
- and
- a force generator disposed between said cassette plate support member and said pad below said cassette plate support member.

A molding machine comprising:
- a bed having a first linear way and a second linear way;
- a moveable platen moveably supported on said bed;
- a fixed platen fixed to said bed;
- an ejector box affixed to said moveable platen, said ejector box having a first wing and an opposed second wing;
- a first pad riding on said first linear way and a second pad riding on said second linear way;
- an outer end of said first wing disposed above said first pad and an outer end of said second wing disposed above said second pad;
- at least one spring disposed between said outer end of said first wing and said first pad and at least one spring disposed between said outer end of said second wing and said second pad;
- one of said outer end of said first wing and said first pad providing a key and another of said outer end of said first wing and said first pad providing a keyway so that said first wing may move upwardly away from first pad and said first pad is constrained to move along said first linear way with said first wing;
- one of said outer end of said second wing and said second pad providing a key and another of said outer end of said second wing and said second pad providing a keyway so that said second wing may move upwardly away from second pad and said second pad is constrained to move along said second linear way with said second wing.
