Abstract
PURPOSE:To increase the strength of a product by preparing the reinforcing cylinder forming a protection layer on the surface of a paper cylinder, engaging a fiber forming body with the core metal of a die via the reinforcing cylinder and executing pressure casting by a matrix molten metal as well. CONSTITUTION:A heat resistant and heat insulating protection layer is formed on the surface of the paper cylinder having stiffness to prepare for a reinforcing cylinder T and a fiber forming body F is formed by the mixed fiber consisting of a carbon fiber and alumina fiber as well. In the production of the cylinder block made of a light alloy, pressure casting is executed by feeding a light alloy matrix molten metal from a runner 17 after arranging a core metal 1, the reinforcing cylinder T and fiber forming body F by fitting them into a die M. Then, a casting cylinder block is subjected to a solution treatment and aging treatment and the reinforcing cylinder T is subjected to thermal decomposition. Due to the gap between the forming body F and core metal 41, reinforcing cylinder T being small the deformation and breakdown of the forming body F are prevented. Consequently the product strength is surely increased.
