Abstract
PURPOSE:To eliminate the vulcanizing process and manufacture a rubber mold by covering the surface of prototype with a silicone rubber material of room temperature curing properties of specific formation, leaving the same for a given period of time as it is and cured. CONSTITUTION:A silicon rubber material of room temperature curing properties to be used is manufactured by uniformly mixing a composition comprising polydiorganosiloxane gum containing alkenyl group, polyorganosiloxane containing hydrogen atom bonded to silicon and platinum catalyst. A bung hole 1 with an injection line 1a for a duplicate product material is installed on a prototype 2 and a sheet 3 manufactured by a silicon rubber material of room temperature curing properties is adhered in a manner to cover the whole outer surface except the bung hole 1 of the prototype 2 and cured. The same is covered with a backup layer 4 of proper thickness, and a rubber mold 5 constituted of a silicon material layer 3 having a hollow section 2a is formed in a couple of backup layers 4. A duplicate product of the prototype 2 is manufactured without the vulcanizing process by injecting an adequate injection material into the hollow section 2a through the bung hole 1 and solidifying the same.
