MOLDED HOLOGRAM APPARATUS METHOD AND PRODUCT

摘要

Holographic lines are formed directly on products by holding a holographic plate (21) and a block (15) under a lip on a frame (11) and mounting the frame for limited movement within a recess (9) in a mold half (5). As a mold cavity is filled, the frame, block and plate and heating tubes (67) connected to the block move in the recess. As the product sets, springs (35) push the frame, block and plate toward the shrinking product controlling the fine holographic lines. Lateral frame recesses (49) receive bolt ends (47) to limit frame travel. Partially withdrawing bolts and removing the tubes releases the frame for withdrawing the block and replacing the holographic plate.
