Patent ID: 8083514

Claim:
A uniform-pressure shaping apparatus, comprising: a first cavity, being a cavity having a first open surface, a first fluid inlet and a first fluid outlet formed at the periphery of the first cavity, and the first cavity being installed on a side of a molding machine, and the molding machine being used for driving the first cavity; a first heat conduction film, installed at the first open surface to seal the first cavity to form a first sealed pressure chamber, and a cold fluid or a hot fluid flowing through the first fluid inlet and the first fluid outlet to the first sealed pressure chamber; a first template, having one surface disposed on the first heat conduction film with its backside aligning towards the first sealed pressure chamber, and another surface of the first template being a first pattern-imprinting surface; a second cavity, being a cavity having a second open surface, a second fluid inlet and a second fluid outlet formed at the periphery of the second cavity, and the second cavity being installed on another side of the molding machine; a second heat conduction film, installed at the second open surface to seal the second cavity to form a second sealed pressure chamber, and the cold fluid or the hot fluid flowing through the second fluid inlet and the second fluid outlet to the second sealed pressure chamber; a second template, having one surface disposed on the second heat conduction film with its backside aligning towards the second sealed pressure chamber, and another surface of the second template being a second pattern-imprinting surface, and an object to be imprinted being disposed on the second pattern-imprinting surface, such that if the first cavity and the second cavity are closed, a containing space is formed between the first pattern-imprinting surface and the second pattern-imprinting surface, and the object to be imprinted is situated in the containing space; and a vacuum pipeline, with an end coupled to the containing space, and another end coupled to a vacuum unit, and the vacuum unit drawing air from the containing space through the vacuum pipeline; wherein a fluid circulation unit is provided for transmitting the hot fluid or the cold fluid to the first sealed pressure chamber and the second sealed pressure chamber, and the hot fluid is used for heating the object to be imprinted to a plastic state, and the cold fluid is used for cooling the object to be imprinted, and the fluid circulation unit produces a uniform pressure at the first sealed pressure chamber and the second sealed pressure chamber by the hot fluid.
