    • A molding method for forming an impeller, includes a mold clamping process having a first mold for forming one side of blades, a second mold firmly clamped with the first mold, and a core arranged at the first mold relative to the blades, the mold clamping process clamping the first mold to the second mold in a state where the core is arranged between the first mold and the second mold, an injecting process injecting resin in a cavity obtained by the mold clamping process, and a mold removing process including the steps of releasing at least the first mold from the clamped state obtained by the mold clamping process to generate an opened portion in the first mold after the resin is hardened, rotating the core about a rotational axis toward the opened portion of the first mold, and separating the core from the resin-molded impeller.
    • 一种用于形成叶轮的成型方法,包括:模具夹紧工艺,其具有用于形成叶片的一侧的第一模具,与第一模具牢固夹紧的第二模具和相对于叶片在第一模具处布置的芯部,模具夹紧 在芯部布置在第一模具和第二模具之间的状态下,将第一模具夹紧到第二模具中,在通过模具夹紧工艺获得的模腔中注入树脂注入工艺,以及脱模工艺,包括以下步骤: 至少将第一模具从通过合模过程获得的夹紧状态释放,以在树脂硬化之后在第一模具中产生开口部分,使芯围绕旋转轴线朝向第一模具的开口部分旋转, 芯从树脂模制叶轮。
