Mechanical ejector

A device, in particular an inclined ejector (1), for demolding a cast component (2) with an undercut from a casting mold for a casting process or an injection molding process with an ejector, comprising:

• an ejector head (16) with a profile which is complementary to the cast component (2) with the undercut and is mounted in a recess (8) so as to be displaceable between a casting position and an ejection position,
• an ejector base (5) movable in a translational direction;
• a link chain (12), which mechanically connects the ejector head (16) with the ejector base (5) in order to implement a force and movement deflection,
• wherein the link chain (12) has a plurality of chain segments (121) engaging in one another in a longitudinal direction, which in particular have low backlash with respect to pull and push in the longitudinal direction and permit tilting relative to one another in at least a first transverse direction,
• wherein the chain segments (121) have a circular cylindrical base body with respect to the longitudinal direction and an axial through-opening (251) in the longitudinal direction, wherein a bendable fixing element (20) is guided through the through-openings (251) of the chain segments (121) in order to hold the chain segment head (25) of one of the chain segments (121) in a corresponding chain segment head receptacle (261) of the at least one further chain segment (121),
• wherein the bendable fixing element (20) is additionally slidably mounted in the through-openings (251) in order to secure a base part (122) of the link chain (12) and the chain segments (121) and a head part (123) of the link chain (12) against mutual shearing in a second transverse direction.
