Abstract
Holographic lines are formed directly on products by holding a holographic plate and a block under a lip on a frame and mounting the frame for limited movement within a recess in a mold half. As a mold cavity is filled, the frame, block and plate and heating tubes connected to the block move in the recess. As the product sets, springs push the frame, block and plate toward the shrinking product controlling the fine holographic lines. Lateral frame recesses receive bolt ends to limit frame travel. Partially withdrawing bolts and removing the tubes releases the frame for withdrawing the block and replacing the holographic plate.
Claims28
Holographic image forming apparatus comprising:
- a frame for movably mounting in a recess in a mold;
- a supply for filling the mold with molding material;
- a block held in the frame;
- a holographic plate mounted on the block in the frame;
- and
- a force producer mounted in the recess beneath the block for urging the block outward in the mold.
A method of making a molded product with an integral holographic section, comprising:
- providing first and second mold halves;
- providing a recess in the first mold half;
- providing a block;
- placing a holographic plate on the block;
- placing the block and the holographic plate in a frame;
- placing the frame in the recess;
- closing the mold halves;
- forming a cavity between the mold halves;
- filling the cavity with molding material;
- forming the product in the cavity;
- urging the holographic plate toward the product in the cavity as the product sets in the cavity;
- and
- opening the mold halves and removing the product with the holographic section impressed on a surface of the product.
