〔産業上の利用分野〕
本発明は、凹凸模様を有する樹脂製品を作製するための
樹脂成形型における可塑性物質（樹脂やセラミックス等
）製の型面にマスタによって凹凸模様を形成する場合に
おいて、前記型面に凹凸模様を付けるように重なったマ
スタを型面から除去する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an uneven pattern created by a master on a mold surface made of a plastic material (resin, ceramics, etc.) in a resin mold for producing a resin product having an uneven pattern. The present invention relates to a method for removing an overlapping master from a mold surface so as to form an uneven pattern on the mold surface.
従来においては、マスタを型面からまくって剥離する、
あるいは、軟質な状態にある可塑性物質をマスタからま
くって剥離することにより、マスタを型面から除去する
方法が採られていた。In the past, the master was rolled up from the mold surface and peeled off.
Alternatively, a method has been adopted in which the master is removed from the mold surface by rolling up and peeling a soft plastic material from the master.
しかしながら、前記の従来方法によるときは、マスタま
たは軟質状態の可塑性物質をまくって剥離するとき、ど
うしても、型面に応力がかかる。それ故、可塑性物質が
軟質にある状態で剥離した場合には型面が変形し易く、
可塑性物質が硬化した状態で剥離した場合には型面に欠
けや割れが生じ易く、特に、型面に形成された凹凸模様
が微細な場合や、形成すべき凹凸模様における凹部の底
が広がっている場合、そのようなｆＩＪｉ向が強い。そ
の結果、型面を精密に成形することが非常にむずかしい
。However, when using the above-mentioned conventional method, stress is inevitably applied to the mold surface when the master or soft plastic material is rolled up and peeled off. Therefore, if the plastic material is peeled off while it is still soft, the mold surface is likely to deform.
If the plastic material peels off in a hardened state, the mold surface is likely to be chipped or cracked, especially if the uneven pattern formed on the mold surface is minute or if the bottom of the recess in the uneven pattern to be formed is widened. If there is, there is a strong tendency towards fIJi. As a result, it is extremely difficult to precisely mold the mold surface.
本発明は、型面を精密に成形することができるようにす
る点にある。The present invention is to enable precise molding of the mold surface.
本発明によるマスタ除去方法の特徴構成は、前記マスタ
を化学的に流動状態に変化させて除去する点にある。そ
して、それによる作用・効果は次の通りである。A characteristic feature of the master removal method according to the present invention is that the master is chemically changed into a fluid state and then removed. The effects and effects thereof are as follows.
溶剤等による溶解（液化）・や膨潤（ゼリー化）、加熱
等による気化といったように、マスタを化学的に流動化

応力を作用させることがなく、しかも、凹凸模様が微細
な場合や凹部の底が広がっていて通常では脱型しにくい
場合であっても、マスタを残すことなく、すみずみまで
確実にマスタを除去できる。Because the master is chemically fluidized and removed by dissolving (liquefying) with a solvent, swelling (jellying), and vaporizing by heating, there is no need to apply stress to the mold surface when removing the master. Furthermore, even if the uneven pattern is minute or the bottom of the recess is wide and difficult to demold under normal conditions, the master can be reliably removed to every corner without leaving any trace behind.
したがって、本発明によれば、型面に形成すべき凹凸模
様が微細で、かつ、複雑であっても、マスタ除去に伴う
型面の変形や破…を回避し、しかも、マスタを確実に除
去して、型面を精密に成形できるに至った。Therefore, according to the present invention, even if the uneven pattern to be formed on the mold surface is minute and complicated, deformation or breakage of the mold surface due to removal of the master can be avoided, and the master can be removed reliably. As a result, we were able to precisely form the mold surface.
