    • An injection molding apparatus includes a vessel, mold, pusher, and thrust providing section. The vessel stores a molding material and has a nozzle hole which is formed in the bottom portion to inject the molding material and a first seal surface formed around the nozzle hole. The mold is made up of stacked members stacked on the lower side of the vessel and is filled with the molding material injected from the vessel. The mold has a sprue communicating with the nozzle hole and a second seal surface formed around the sprue. The stacked members respectively have third seal surfaces at portions where the members are in contact with each other. The pusher pressurizes the molding material in the vessel. The thrust providing section provides a thrust to the pusher to pressurize one of the pusher and the mold through the molding material in the vessel. The thrust providing section brings the first, second, and third seal surfaces into tight contact with each other by providing a downward thrust to the pusher with respect to the mold. An injection molding method is also disclosed.
    • 注射成型装置包括容器,模具,推动器和推力提供部。 容器存储成型材料,并且具有形成在底部中的注射成型材料的喷嘴孔和形成在喷嘴孔周围的第一密封面。 模具由堆叠在容器的下侧上的堆叠构件组成,并且填充有从容器注入的模制材料。 模具具有与喷嘴孔连通的浇道和在浇口周围形成的第二密封表面。 层叠构件在构件彼此接触的部分处分别具有第三密封表面。 推动器对容器中的成型材料加压。 推力提供部分为推动器提供推力以通过容器中的模制材料对推动器和模具中的一个进行加压。 推力提供部分通过相对于模具向推动器提供向下的推力使第一,第二和第三密封表面彼此紧密接触。 还公开了一种注射成型方法。
