Flex plate for guiding device of injection molding machine
A flex plate for a guiding device of an injection molding machine includes a body extending between a front surface, a back surface, a top surface, and a bottom surface. A plurality of through holes extend between the top surface and the bottom surface for aligning the flex plate with a foot of the guiding device, and a plurality of guide shoe holes formed in the bottom surface of the flex plate couple the flex plate to a guide shoe of the guiding device. A front plate couples the front surface of the flex plate to the foot of the guiding device, and a plurality of slots define a central portion of the flex plate. The central portion of the flex plate is elastically deformable about a torsional axis and can pivot relative to the guide shoe and foot of the guiding device.
1 . A flex plate for a guiding device of an injection molding machine, the flex plate comprising:
a body extending between a front surface, a back surface, a top surface, and a bottom surface;
a plurality of through holes extending between the top surface and the bottom surface for attaching the flex plate with a foot of the guiding device;
a plurality of guide shoe holes formed in the bottom surface of the flex plate for coupling the flex plate to a guide shoe of the guiding device;
a front plate for coupling the front surface of the flex plate and the foot of the guiding device; and
a plurality of slots defining a central portion of the flex plate;
wherein the central portion of the flex plate is elastically deformable about a torsional axis such that the central portion can pivot relative to both the guide shoe and the foot of the guiding device.
2 . The flex plate of claim 1 , wherein the plurality of slots defining the central portion of the flex plate extend between the top surface and the bottom surface of the flex plate.
3 . The flex plate of claim 1 , wherein the plurality of slots comprise a plurality of U-shaped slots.
4 . The flex plate of claim 3 , wherein the plurality of U-shaped slots include a plurality of endpoints.
5 . The flex plate of claim 4 , wherein the plurality of endpoints of the plurality of U-shaped slots are curved in shape.
6 . The flex plate of claim 1 , wherein the plurality of slots comprise an outer slot and an inner slot.
7 . The flex plate of claim 1 , wherein the plurality of through holes are formed within the central portion of the flex plate.
8 . The flex plate of claim 1 , wherein the plurality of guide shoe holes are formed outside of the central portion of the flex plate.
9 . The flex plate of claim 1 , further comprising a plurality of apertures in the front surface for coupling the flex plate to the front plate.
10 . The flex plate of claim 1 , further including a connector for coupling the front plate to the foot of the guiding device.
11 . The flex plate of claim 10 , wherein an end of the connector for coupling the front plate to the foot of the guiding device has a truncated diamond-shaped cross-section, the end of the connector to be received in the foot of the guiding device forming a snug-fit with the foot of the guiding device in a vertical direction and loose fit in a lateral direction.
