Document Type and Number:
WIPO Patent Application WO/2018/043191
Kind Code:
A1
Abstract:
[Problem] To transfer a minute shape onto a surface of a molded article with high accuracy and high efficiency without foaming the surface of the molded article. [Solution] A part of a cavity 6 is constituted of a tip 11b of a cavity piece 11. The cavity piece 11 slidably moves along a guide hole 12 formed in a mold body 3 between a position constituting the part of the cavity 6 and a retracted position distant from the cavity 6. A space 12a of the guide hole 12 that is created when the cavity piece 11 moves to the retracted position is connected to an external plasticization fluid supplying device 21 via flow paths 18 and 20. A molded article 8 inside the cavity 6 has a surface facing the space 12a of the guide hole 12 that is plasticized by the plasticization fluid introduced into the space 12a. The tip 11b of the cavity piece 11 is pressed against the plasticized surface of the molded article 8, so that a minute shape of the tip 11b of the cavity piece 11 is transferred.
