Abstract
An actuator (100) for a molding system (900) is disclosed. The actuator (100) includes a linear actuator (102). The linear actuator (102) is configured to move a payload (160) relative to a support structure (170). The linear actuator (102) is connectable to the support structure (170) and the payload (160). The actuator (100) also includes a first compensator (104). The first compensator (104) is configured to compensate for a relative misalignment between the linear actuator (102) and the payload (160). The actuator (100) further includes a second compensator (106). The second compensator (106) is configured to compensate for a relative misalignment between the linear actuator (102) and the support structure (170).
Claims36
An actuator (100, 200, 300, 400A, 400B) for a molding system (900, 950), the actuator (100, 200, 300, 400A, 400B) comprising:
- a linear actuator (102, 202, 302, 402A, 402B) configured to move a payload (160, 360, 460) relative to a support structure (170, 370, 470), the linear actuator (102, 202, 302, 402) being connectable to the support structure (170, 370, 470) and the payload (160, 360, 460);
- a first compensator (104, 204, 304, 404A, 404B) configured to compensate for relative misalignment between the linear actuator (102, 202, 302, 402A, 402B) and the payload (160, 360, 460);
- and
- a second compensator (106, 206, 306, 406A, 406B) configured to compensate for relative misalignment between the linear actuator (102, 202, 302, 402A, 402B) and the support structure (170, 370, 470).
A molding system (900) comprising:
- a clamp assembly (130) including:
- a first platen (132);
- a second platen (134);
- and
- a third platen (136);
- and
- an actuator (100, 200) including:
- a linear actuator (102, 202) configured to move the second platen (134) between the first platen (132) and the third platen (136);
- a first compensator (104, 204) configured to compensate for relative misalignment between the linear actuator (102, 202) and the second platen (134);
- and
- a second compensator (106) configured to compensate for relative misalignment between the linear actuator (102, 202) and the third platen (136).
A molding system (950) comprising:
- a clamp assembly (330) including:
- a stationary platen (332);
- a movable platen (334);
- and
- an actuator (300) including:
- a linear actuator (302) configured to move the movable platen (334) relative to the stationary platen (332);
- a first compensator (304);
- and
- a second compensator (306), wherein the first compensator (304) and the second compensator (306) are configured to cooperate to prevent, at least partially, transmission of bending stress and strain to the linear actuator (302).
An injection unit (800) comprising:
- an injection rear housing (812);
- an injection front housing (810);
- and
- an actuator (400A, 400B), the actuator (400A, 400B) including:
- a linear actuator (402A, 402B) configured to move the injection front housing (810) relative to the injection rear housing (812);
- a first compensator (404A, 404B);
- and
- a second compensator (406A, 406B), wherein the first compensator (404A, 404B) and the second compensator (406A, 406B) are configured to cooperate to prevent, at least partially, transmission of bending stress and strain to the linear actuator (402A, 402B).
