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.

Claims (17)

1. 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

wherein the respective tie-bar accommodation corners are coupled to the peripheral portion of the mold-support structure,

the respective tie-bar accommodation corners are supported by the peripheral portion of the mold-support structure,

the respective tie-bar accommodation corners are supported by connection portions associated with the intermediate structure, and

the support provided by the peripheral portion is greater than the support provided by the connection portions.

2. The platen of claim 1 , wherein:

the coupling between the respective tie-bar accommodation corners and the peripheral portion of the mold-support structure has stiffer coupling effect relative to the connection portions.

3. The platen of claim 1 , further comprising:

ribs coupling the respective tie-bar accommodation corners to the peripheral portion of the mold-support structure, the ribs having stiffer coupling effect relative to the connection portions.

4. The platen of claim 3 , wherein the ribs are fully detached from the intermediate structure.

5. The platen of claim 4 , wherein the ribs extend substantially perpendicular to the peripheral portion of the mold-support structure.

6. The platen of claim 1 , wherein the mold-support structure defines respective tie-bar channels.

7. The platen of claim 1 , wherein the respective tie-bar accommodation corners are configured to receive and accommodate respective tie-bar locking structures.
