ることができる。In manufacturing the brake caliper, a metal pipe 2 is set in a mold in advance, and thereafter, a molten aluminum alloy is poured into the mold and casting is performed in such a manner that the pipe is cast. It is. In this case,
The molten aluminum alloy has a thickness greater than the maximum thickness of the product part.
Low-speed laminar flow at a gate inflow speed of 0.15 to 0.4 m / s
Injection by filling method, pouring temperature 700-800 ℃ 2 stages
Solidified under a pressure of 500~2000kgf / cm 2 by the pressure plunger
Is performed. With such a high pressure solidification casting method,
If the pressure is applied during solidification, the molten metal will be strongly adhered to the mold.
To increase the solidification rate and obtain a dense and uniform structure
Can improve the tensile strength and fatigue strength.
The bonding force with the step 2 is also improved. As the material of the metal pipe, Al pipe, Ni pipe, Ni

Can be reduced in size and weight. Therefore, the degree of freedom in designing the caliper in the wheel is increased, and a design that has been impossible at the design stage can be adopted. Also, since the hydraulic pressure supply hole can be formed in a gentle curve and straight line shape without having the zigzag shape shown in FIG. 2, the oil flow resistance is small, the hydraulic pressure propagation speed increases, and the responsiveness of the brake operation increases. Is improved. Furthermore, machining only requires drilling the holes 2a, 2b communicating with the cylinders 1A, 1B in the pipe 2, so that the machining cost can be reduced.
