Swash plate type compressor piston wherein inner bottom surface of hollow head section has 3-dimensional configuration nonaxisymmetric with respect to its centerline |
摘要 |
A method of producing a body member for a swash plate type compressor piston, the body member including a head section and an engaging section formed integrally with the head section, comprising the steps of preparing a die-casting device including a casting mold consisting of two mold halves which are spaced apart from each other and butted together in a direction perpendicular to a centerline of the head section and which have respective molding surfaces; and a slide core which is slidably movable in a direction parallel to the centerline such that the slide core is advanced into and retracted from the casting mold, the slide core cooperating with the molding surfaces to define therebetween a mold cavity when the slide core is advanced into the casting mold, the mold cavity having a configuration following that of the body member, at least a front end portion of the slide core having a nonaxisymmetric configuration with respect to a centerline of the slide core; and die-casting the body member using the die-casting device, such that the head section has an inner bottom surface having a three-dimensional configuration nonaxisymmetric with respect to the centerline of the head section corresponding to the nonaxisymmetric configuration of the front end portion of the slide core.
