摘要： An aluminum alloy die casting method comprising the steps of providing a die casting machine having a gate for allowing passage of molten aluminum alloy, setting a flow rate of the molten aluminum alloy at the gate to be in a range of 5 m/sec to 15 m/sec, and press-injecting the molten aluminum alloy into a cavity of a die. With this arrangement, it becomes possible to obtain a weldable casting with no entrapment of air. An aluminum alloy for a vehicular part, which is formed of a die cast product manufactured by the die casting method of the present invention, is weldable and also dense in structure. As a result, these vehicular parts formed of the die-cast products are manufactured on a large scale at a low cost.

摘要： To adopt die casts product as parts of a vehicle body frame. A vehicle body frame is provide with an alumite treating, showing that brightness and appearance of pivot plates which are die cast products differ from those of non-die cast products, head pipes, longitudinal pipes and cross pipe. By carrying out a local coating treatment on the pivot plates, the pivot plates are provided with a color the same as that of the pipe, the longitudinal pipes and the cross pipe. By making die cast products portion of constituent parts, the fabrication cost of the vehicle body frame can be reduced.

摘要： PROBLEM TO BE SOLVED: To obtain a die cast product which can be welded without using a high-level control technique or changing devices by setting a passing velocity at a gate part in a specific range. SOLUTION: In an Al alloy die casting, gas entrainment can be significantly reduced by restraining a gate velocity up to 15 m/sec. Therefore, a die cast product has a fine surface and no bubbles so as to be weldable. When the gate velocity is less than 5 mm/sec., the molten metal is cooled during the process of filling in a cavity, resulting in misrun. Then, the gate velocity is set to be 5-15 m/sec. Furthermore, the usage of a die releasing agent for separating the cast product from the die is effective, and a volatile component such as a high polymer system synthetic oil is added to the die releasing agent, which is to be adhered to the die. In this case, the volatile component is thermal decomposed to generate hydrogen gas, whereby the component to be volatilized at 700 deg.C or above is preferably contained at 30 wt.% or less.

摘要： PROBLEM TO BE SOLVED: To provide a clutch outer less liable to generate a cast cavity or a rippled surface and capable of securing a centrifugal strength and a torsional strength over the entire length of fins by distributing stress against a centrifugal force and a torsional torque acting on the fins of the clutch outer.
SOLUTION: In this clutch outer of a multi-disk clutch, multiple sheets of friction plates and clutch plates in a stacked state are stored in a space between the clutch outer 11 in which a plurality of cutouts directed in the axial direction of a bottomed cylindrical body and cut out are formed in the circumferential direction and a clutch inner in which a plurality of grooves directed in the axial direction are formed in the outer peripheral surface in the circumferential direction, and the outer peripheral projected parts of the friction plates are fitted to the cutouts of the clutch outer and the inner peripheral projected parts of the clutch plates are fitted to the grooves of the clutch inner, and the friction plates and the clutch plates are pressed against each other by a pressing plate disposed on the opening end face side of the clutch outer to transmit a power. A continuous annular part 16 free from cutout is formed integrally with the opening end part of the clutch outer 11.
