Problems solved by technology

[0009] However, these measures are not only disappointing in terms of equipment cost, operating cost, and production time, but also make the workpiece bear excessively high temperature and surface pressure, so the expansion of the side of the material increases during forming, and the expansion of the material after forming is completed. The side requires post-processing

Embodiment Construction

[0031] Next, a thermocompression forming apparatus according to an embodiment of the present invention will be described with reference to the drawings.

[0032] figure 1 The overall structure of the thermocompression forming apparatus according to the first embodiment of the present invention is shown.

[0033] The hot press forming apparatus 100 is composed of a combination of a general-purpose press device and a die system for hot press forming. The general-purpose pressure device includes a base 102 fixed to the ground and a slide plate 104 arranged above the base 102 . The slide plate 104 is driven by a driving device 106 and moves vertically along a not-shown support so as to approach and move away from the base 102 . The driving device 106 may also include, for example, a servo motor that drives the slide plate 104 and a controller that drives and controls the servo motor. As the drive device 106, a hydraulic actuator may be used instead of a drive device using a ser...

Abstract

The present invention provides a hot press molding apparatus. A contact state between a thermo plastic plate and a stamper is uniformed during hot press molding. The hot press apparatus 100 provides with a press apparatus provided with a bolster 102, a slide 104, a driving apparatus 106 for driving the slide 104, a hot press molding apparatus 100 with a die set 112 and 114 and the die set 112 and114 inserted into a flame 120 with a holding space inside, a heating plate 136 sliding so as to change a volume of an accommodating space, a rubber member 138 to be compressed so that a holding spacemay be reduced if a framing table slides and a flexible ceiling panel 140 set to the flame 120 having an inner face facing the holding space, and an exterior face supporting the stamper 142 facing the holding space. When the heating plate 136 slides, the accommodating space to be reduced, the ceiling panel 140 is deformed outside by receiving an elastic force inside by the rubber member 138 compressed.

Description

technical field [0001] The present invention relates to a thermocompression forming device for duplicating a fine shape pattern on the surface of a thermoplastic plate by pressing a stamping die, and a metal mold system for the device. Background technique [0002] This type of thermocompression molding machine is used to form optical components and highly patterned panels with fine shape patterns on the surface, such as light guide plates and diffuser plates for backlights of liquid crystal displays, lenses, and optical disk substrates. Such a metal mold configuration for hot press forming has been disclosed in Patent Document 1, for example. According to its disclosure, a plate-shaped stamping die is installed on a heating / cooling plate having a heating / cooling member, the stamping die is heated or cooled by the heating / cooling plate, and the stamping die is pressed against the thermoplastic resin by the heating / cooling plate surface of the board. [0003] Patent Documen...
