Title: Manufacture of fiber reinforced resin valve lifter
Inventor: HOSOYA ICHIRO
IPC: B29C39/04
Filed: 1987-12-23
Abstract: PURPOSE:To improve the wear resistance of only the outer peripheral surface of a cylindrical part, which is the sliding part of a valve lifter, by a method wherein short-fiber-containing resin is filled in a cavity to form the valve lifter and the resin is formed under the condition that a mold constituting said cavity is rotated about its axis line. CONSTITUTION:Fiber reinforced resin B containing short fiber C is filled in a cavity, which is constituted by a rotor member 4, a middle force 5 and a top force 8, and heated and melted by means of heating mechanism. At the start of melting, the top force 8, the middle force 5 and the rotary member 4 are rotated and simultaneously the top force 8 is lowered so as to pressurize the fiber reinforced resin B. At this time, the rotational speed and forming pressure are set in response to the shape and weight of a valve lifter to be formed Ab. Since the short fibers C gather on the outer peripheral surface side Ab1 of a cylindrical part, which slides on the cylinder head, due to a centrifugal force at rotation, the fiber content is enhanced only on said side Ab1, resulting in allowing to improve the wear resistance of the valve lifter without increasing its weight.
