PURPOSE:To improve the moldability and quality by a method wherein after artificial turf main body molding resin or conductive part molding resin is injected into a conductive part mold cavity or an artificial turf mold cavity through one injection device, the conductive part molding resin or the artificial turf main body molding resin is injected through the other injection device. CONSTITUTION:The artificial turf molding resin is injected into a mold cavity A and an artificial turf main body 1 is molded. Since a conductive part molding cavity B is blocked up by a core pin 12, the artificial turf molding resin is not cast into the conductive part molding cavity B. Then the core pin 12 is moved backward a little by operating an air cylinder and a leg part molding cavity 18 of a conductive part is formed in a part into which the core pin 12 has been fitted. Then when the conductive part molding resin is injected into the mold cavity B, the artificial turf main body 1 and a conductive part 23 and molded in a body, then a mold is broken, a molded product is released from the molded and a cycle is completed. |
