Filed: 1988-01-14
Abstract: PURPOSE:To drastically reduce the deteriorating ratio of a product and to surely remove sands in a product for short time by using salt or sand as main material and adding the specific concn. of CaC2 to this. CONSTITUTION:After adding 1-10wt.% CaC2 to salt core sand core using the salt or the sand as the main material the pressurization and heating-formation are executed. When the added quantity of CaC2 is a little, as generated quality of C2H2 with action of water is a little, collapsiblity of the core is poor, and when the CaC2 is so much, as contacting action with moisture in the air is executed, the prevention of moisture absorption in the core is difficult. When product taking out from the metallic mold is dipped into the water or the water is sprayed, the core in the product is rapidly collapsed and removed with C2H2 from CaC2 generating by contacting action with the water. Further, by adding phenol resin as binder combining salt grain at the prescribed quantity, the pressurization and heating-formation may be executed. By this method, the sands, etc., from the product can be surely removed and the removing work of the core can be drastically improved.
