Embodiment Construction

[0035] Hereinafter, a press molding apparatus according to one embodiment of the present invention will be described using the drawings.

[0036] FIG. 1 is a diagram showing a schematic configuration of a press forming apparatus 1 according to the present embodiment.

[0037] As shown in the figure, the press-forming apparatus 1 includes a press unit 30 for pressing the object 2 and a structure for controlling the press unit 30 . The structure for controlling the pressing part 30 includes: servo motors 11, 11 as motors for moving the slider 21 up and down; a power converting mechanism (with wheels 12, 12, timing belts 13, 13, ball screws 14, 14); a controller 17 for driving the servo motors 11, 11; and a temperature control device 60 for adjusting the temperature of the die 35. The controller 17 outputs control signals for driving the servo motors 11, 11 through position control according to the outputs of the slider position detection devices 23, 23; to drive the control si...

Abstract

In a pressing shaped device, a die is easy to be taken off from a machining object when finishing transfer printing pattern. The pressing shaped device (1) comprises: upper and lower dies (35a, 35b); regulating temperature boards (34a, 34b) for heating and cooling the upper and lower dies (35a, 35b); and an air current nozzle (41). To heat the regulating temperature boards (34a, 34b) until its temperature is above the softening temperature of the machining object (2), under the vacuum or decompression state, pressing the dies (35a, 35b) on the two surfaces of the machining object (2) to press shaped. After figuration, cooling the regulating temperature boards (34a, 34b) to various temperatures, so as to enlarge the distance of the dies (35a, 35b) with Delta H only. Opening the vacuum chamber, and wafting the air current to the gap between the dies (35a, 35b) generated by thermal distortion and the machining object (2).

Description

technical field [0001] The present invention relates to a press molding in which a stamper having a fine pattern is pressed on the surface of a thermoplastic resin sheet to transfer a fine pattern on the surface of the thermoplastic resin sheet, and in particular, relates to a method for easily removing heat from heat after press molding. A technique for releasing a stamper from a moldable resin plate. Background technique [0002] An apparatus for thermal transfer press-molding fine patterns in a vacuum or decompressed vacuum chamber using a thermoplastic resin as a material is known. This press molding apparatus is used, for example, to manufacture a thermoplastic resin light guide plate used for a liquid crystal display panel, and the like. [0003] In such a press-molding apparatus, when a stamper having a fine pattern is pressed on the surface of a thermoplastic resin plate and the transfer of the pattern is completed, the thermoplastic resin must be released from the ...
