Abstract
A clamping assembly for injection molding apparatus which includes a base frame and a pair of support posts, each formed with a cutout. A fixed platen is connected to, or is integrally formed with, one of the support posts while a movable platen is connected to the other support post. Finally, a support structure is provided over which the movable platen slides. In one embodiment, the support structure is a floating support which is connected to the two support posts.
Claims19
A clamping assembly, comprising:
- (a) a base frame having a first end and a second end;
- (b) a first support post connected to, or integrally formed with, said first end of said base frame, said first support post having a first cutout;
- (c) a fixed platen connected to, or integrally formed with, said first support post;
- (d) a second support post connected to, or integrally formed with said second end of said base frame, said second support post having a second cutout;
- (e) a movable platen movably connected to said second support post;
- and
- (f) a support structure for slidably supporting said movable platen;
- wherein an upper portion of each of said first and second support posts located substantially above said first and second cutouts extends substantially horizontally so that a horizontally applied force tends to compress said upper portion while a lower portion of said first and second support posts located substantially below said first and second cutouts extends in an arcuate manner so that said horizontally applied force tends to bend, as well as compress, said lower portion.

A clamping assembly, comprising:
- (a) a base frame having a first end and a second end;
- (b) a first support post connected to, or integrally formed with, said first end of said base frame;
- (c) a fixed platen connected to, or integrally formed with, said first support post, said first support post including a proximal first support post element located at or near a lateral edge of said fixed platen and a distal first support element located outwardly of said proximal first support post element;
- (d) a second support post connected to, or integrally formed with, said second end of said base frame;
- (e) a movable platen movably connected to said second support post, said second support post including a proximal second support post element located near a lateral edge of said movable platen when said movable platen is in a fully retracted condition and a distal second support post element located outwardly of said proximal second support post element;
- and
- (f) a support structure for slidably supporting said movable platen;
- wherein said proximal and distal first support post elements are connected to each other by a first top elastic member and a first bottom elastic member, the elasticity of said first bottom elastic member being larger than the elasticity of said first top elastic member, while said proximal and distal second support post elements are connected to each other by a second top elastic member and a second bottom elastic member, the elasticity of said second bottom elastic member being larger than the elasticity of said second top elastic member.
