Abstract
Disclosed are: (i) a platen of a molding system, (ii) a molding system having a platen, (iii) a clamp of a molding system having platens, and (iv) a molded article.
Claims28
A platen of a molding system, the platen comprising:
- a force-receiving structure having respective tie-bar accommodation corners each defining tie-bar channels configured to receive a respective tie bar, responsive to the force-receiving structure receiving a clamping force, the respective tie-bar accommodation corners resist, at least in part, coplanar disorientation relative to a mold-support structure of the platen.
A platen of a molding system, the platen comprising:
- a mold-support structure having a central portion, the mold-support structure having a peripheral portion surrounding the central portion;
- a force-receiving structure offset from the mold-support structure;
- and
- an intermediate structure connecting the force-receiving structure to the central portion, the intermediate structure does not connect the force-receiving structure to the peripheral portion,
- the force-receiving structure having respective tie-bar accommodation corners each defining tie-bar channels configured to receive a respective tie bar, responsive to the force-receiving structure receiving a clamping force, the respective tie-bar accommodation corners resist, at least in part, coplanar disorientation relative to the mold-support structure.

- and
- a platen stroke actuator coupled to at least one of the platens, and configured to stroke the platens relative to each other,
- the platens each including:
- a mold-support structure having a central portion, the mold-support structure having a peripheral portion surrounding the central portion;
- a force-receiving structure offset from the mold-support structure;
- and
- an intermediate structure connecting the force-receiving structure to the central portion, the intermediate structure does not connect the force-receiving structure to the peripheral portion,
- the force-receiving structure having respective tie-bar accommodation corners each defining tie-bar channels configured to receive a respective tie bar, responsive to the force-receiving structure receiving a clamping force, the respective tie-bar accommodation corners resist, at least in part, coplanar disorientation relative to the mold-support structure.
