Embodiment Construction

[0039] see figure 1 , which is a schematic diagram of the first embodiment of the isostatic molding system of the present invention. In the figure, an isostatic molding system 1 includes an isostatic molding device 2 , a temperature control device 3 and a pressure device 4 .

[0040]The isostatic molding device 2 includes a first cavity 20 , a first template 22 and a second template 23 . The first cavity 20 is disposed on one side of a mold machine 5 , and the first cavity 20 has a first opening 201 . In the first cavity 201 lower than the first opening 201 , a first heat conduction film 24 is disposed, and the first heat conduction film 24 closes the first cavity 20 to form a first airtight pressure chamber 21 . A first liquid inlet and outlet 25 is provided anywhere around the first airtight pressure chamber 21 . The first template 22 is arranged on the first heat conducting film 24 , and the second template 23 is arranged on the other side of the mold machine 5 . An imp...

Abstract

The invention discloses an isostactic pressing method and an isostactic pressing system. The isostactic pressing system comprises an isostactic pressing device, a temperature control device and a pressure device, wherein the isostactic pressing device comprises a closed pressure cavity; an imprinting object is placed in the isostactic pressing device; the closed pressure cavity is connected with the pressure device, so as to form a sealed area; a working fluid is filled in the sealed area; and the pressure device makes the working fluid pressurized. When the isostactic pressing device is closed, the temperature of the working fluid is raised by the temperature control device, so as to soften the imprinting object, then the pressurized working fluid presses the imprinting object through a heat-conducting film, and finally, the imprinting object is formed in the isostactic pressing device. Through the adoption of the linear pressure equalizing and linear heat equalizing properties of liquid and the like, the imprinting object can be pressed and heated uniformly.

Description

technical field [0001] The present invention relates to an isostatic forming method and its system, in particular to an isostatic forming method with liquid as a pressure transmission medium and its system. Background technique [0002] Existing thermoforming is to place the imprinted object in the cavity of an embossing mold. The imprinted mold includes a set of upper and lower templates, each of which has an embossing surface with an embossing pattern. After closing the embossing mold between the surfaces of the upper and lower templates with embossing patterns, the upper and lower templates will form a closed mold cavity, and the embossed objects are stored in the closed mold cavity. After the stamping mold is closed, the stamping mold will be heated to soften the stamped object to a plastic state, and then the stamping mold will press the stamped object to form the embossed patterns of the upper and lower templates on the stamped object, and finally cool down Imprinted ...
