AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1-7 is confirmed.
1. A moving apparatus operable for moving a tool of an injection molding machine, said moving apparatus comprising:
a beam comprising a fixed beam part and a moving beam part, wherein the fixed beam part is configured to extend longitudinally in generally parallel relation to the moving beam part generally parallel to a Z axis;
a carriage for carrying said tool, wherein said carriage is mounted to the moving beam part for reciprocal movement along the Z axis;
an actuator mounted between said fixed beam part and said moving beam part operable to move said moving beam part in said reciprocating movement parallel to a Y axis;
a first guide shaft interconnected to said fixed beam part and a first bushing device interconnected to said moving beam part, said first bushing device being supported by and movable on said first guide shaft to permit movement of said moving beam part relative to said fixed beam parallel to the Y axis;
a second guide shaft interconnected to said fixed beam part and a second bushing device interconnected to said moving beam part, said second bushing device supported by and movable on said second guide shaft to permit movement of said moving beam part relative to said fixed beam parallel to the Y axis;
a movement limitation mechanism operable for limiting the movement of said moving beam part relative to said fixed beam part, wherein said movement limitation mechanism comprises a first stopping device interconnected to said fixed beam part, said first stopping device operable and positioned to engage said first bushing device to limit the movement of said first bushing device, and a second stopping device interconnected to said fixed beam part, said second stopping device operable and positioned to engage said second bushing device to limit the movement of said second bushing device;
wherein said first and second stopping members are independently operable to thereby adjust the longitudinal orientation of said moving beam part about a transverse axis relative to the longitudinal orientation of fixed beam part, whereby the tool when attached to moving beam part will be able to properly engage the parts being ejected from the mold when tool is in an inbound position.
