摘要： The present invention provides an impeller in which a metallic bush can be inserted correctly into a synthetic resin impeller main body manufactured by resin molding using a die, and a determination as to whether or not the impeller has been manufactured correctly can be made easily. The impeller comprises: a metallic bush comprising a circumferential boss portion having a substantially truncated cone-shaped throttle portion positioned on a front surface axial end side, a periaxial support boss portion positioned in an axial center, and a circumferential protruding portion positioned on a back surface axial end side; and an impeller main body made of synthetic resin and formed with a V-shaped bulging portion that bulges axially in the center of a front surface side of a disk-shaped vane portion fulcrum, in which a plurality of vanes are formed integrally on the periphery of the V-shaped bulging portion. An outer diameter of the circumferential protruding portion of the bush is formed to be smaller than an outer diameter of an axial end location of the throttle portion, the circumferential protruding portion is positioned on a back surface side of the V-shaped bulging portion, and the bush is inserted into the V-shaped bulging portion.
摘要翻译：本发明提供一种叶轮，其中可以将金属衬套正确地插入到通过使用模具的树脂成型制造的合成树脂叶轮主体中，并且可以容易地确定是否正确地制造了叶轮。叶轮包括：金属衬套，其包括周向凸台部分，其具有位于前表面轴向端侧的基本上截头圆锥形的节流部分，位于轴向中心的轴向支撑凸台部分和位于背面的周向突出部分表面轴向端面; 以及由合成树脂制成的叶轮主体，其形成有V形凸起部，该V形凸出部在圆盘形叶片部支点的前表面侧的中心轴向凸出，其中多个叶片一体地形成在周边的V形凸出部分。衬套的周向突出部的外径形成为小于节流部的轴向端部的外径，周向突出部位于V形凸出部的背面侧，衬套插入到V形凸出部分中。

摘要： The present invention provides a manufacturing method for an impeller with which molding and high-quality finishing can be performed extremely easily and quickly through resin molding using a die, and an impeller manufactured by the impeller manufacturing method. A metallic bush is disposed in a die, whereupon a resin material is injected through a gate in the die. A connecting portion between an unnecessary resin portion formed from residual resin material in the gate and a resin impeller main body molded around the bush is formed to be thin, and the unnecessary resin portion is removed from the impeller main body using pushing or withdrawing means.
摘要翻译：本发明提供一种用于叶轮的制造方法，通过使用模具的树脂成形以及通过叶轮制造方法制造的叶轮，能够非常容易且快速地进行成型和高质量的整理。金属衬套设置在模具中，于是树脂材料通过模具中的浇口注入。由浇口中的残留树脂材料形成的不需要的树脂部分和围绕衬套模制的树脂叶轮主体之间的连接部分形成为薄而不必要的树脂部分通过推压或取出装置从叶轮主体移除。
