< Topic >At the time of creating the formation die of smooth tooth profile, the supply stick of the liquefied gypsum which can remove the excessive moisture is offered.SolutionsAttaching part 2 of the liquefied gypsum is provided in the Tip of long computer 1, attaching part 2 is formed with the water absortion power material which consists of the lumber of non paint, at the same time it is flat and the concave falling section 2a which concave falling is done is formed on the center line which parallels to the longitudinal direction. When injecting the liquefied gypsum to prototype, the excessive moisture of the liquefied gypsum is adsorbed by the porous operation of the supply stick, the surface of plaster mold after the hardening becomes smooth ones which do not have the section which is lacked ardently.< Choice figure >Drawing 1【課題】平滑な歯型の成形型の作成において、余分な水分を除去しうる液状石膏の供給棒を提供する。【解決手段】細長い本体1の先端部に液状石膏の保持部2を設け、保持部2を非塗装の木材からなる吸水性材料で構成し、且つ偏平でその長手方向に沿う中心線上に凹陥した凹陥部2aを形成する。液状石膏を原型に注入する時、供給棒の多孔質の作用によって、液状石膏の余分な水分は吸着され、硬化後の石膏型の表面は切欠く部のない滑らかなものとなる。【選択図】図1
