    • PROBLEM TO BE SOLVED: To provide 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 the impeller has been manufactured correctly is made easily. SOLUTION: The impeller comprises: the metallic bush 2 comprising a circumferential boss portion 21 having a substantially truncated cone-shaped throttle portion 211 positioned on a front surface axial end side, a periaxial support boss portion 22 positioned in an axial center, and a circumferential protruding portion 24 positioned on a back surface axial end side; and the impeller main body A made of synthetic resin and formed with a V-shaped bulging portion 11 that bulges axially in the center of a front surface side of a disk-shaped vane portion fulcrum 1, in which a plurality of vanes 12 are formed integrally on the periphery of the V-shaped bulging portion 11. An outer diameter of the circumferential protruding portion 24 of the bush 2 is formed to be smaller than an outer diameter of an axial end location of the throttle portion 211, the circumferential protruding portion 24 is positioned on a back surface side of the V-shaped bulging portion 11, and the bush 2 is inserted into the V-shaped bulging portion 11.

    • PURPOSE:To cause a detection to be easily and accurately achieved by a method in which the air inducing groove and the air exhausting groove connected to an insert keeping groove on the surface of a bottom force are formed, and said both grooves are joined by way of an engraving space. CONSTITUTION:A plurality of engraving spaces 6 and a plurality of insert keeping grooves 7, 8 connected to said engraving spaces 6 are formed on a bottom force. The air inducing groove 9 connected to one groove 7 of said insert keeping grooves is formed on the upper surface of the bottom force 5, and both ends 9a, 9b of said groove 9 are closed. The air exhausting groove 10 connected to another insert keeping groove 8 of said grooves is formed. Both ends 10a, 10b of said groove 10 are opened on the side surface of the bottom force 5 and connected to the atmosphere. Insert members 3 are inserted and packed into the insert keeping grooves 7, 8 of the bottom force 5, and the top and bottom forces 4, 5 are closed. At this state, compressed air is supplied from a feeding pipe 14, and introduced into the air inducing groove 9 of the bottom force 5 through an air hole 13 of the top force 4. Consequently, at the condition where the top and bottom forces are clamped, the presence and absence of the insert member and its posture in packed state may be accurately detected by the rising and lowering of the air pressure in an air feeding side, and the inspection may be achieved at the position of the injecting operation.
    • 目的:通过形成与底部力的表面上的插入保持槽连接的导风槽和排气槽的方法容易且准确地实现检测,并且所述两个沟槽通过连接 的雕刻空间。 构成:连接到所述雕刻空间6的多个雕刻空间6和多个插入保持槽7,8形成为底部力。 连接到所述插入物保持槽的一个槽7的导气槽9形成在底力5的上表面上,并且所述槽9的两端9a,9b闭合。 形成与所述槽的另一个刀片保持槽8连接的排气槽10。 所述槽10的两端部10a,10b在底力5的侧面开口,与大气连通。 插入构件3被插入并包装到底部力5的插入物保持槽7,8中,并且顶部和底部力4,5被关闭。 在这种状态下,压缩空气从供给管14供给,并通过顶部力4的通气孔13被引入到底部力5的导风槽9中。因此,在顶部和底部力为 通过空气供给侧的空气压力的上升和下降可以精确地检测插入构件的有无和其处于包装状态的姿势,并且可以在注入操作的位置实现检查。
