PURPOSE:To make it unnecessary to remove burrs after injection molding, by placing a bottom-metal mold on each station of a rotary table and arranging the first injection molding machine at right angles to the bottom-metal mold and also arranging the second injection molding machine at right angles to the bottom-metal mold in the departed position from the first injection molding machine by 2 or 3 stations. CONSTITUTION:A lower sole 5 is left in a sole mold 10 as it is and each mold is relieved. A dummy last 8 is raised upward and exchanged to the last 13 fitted at the opposite side of the dummy last 8. In the last 13, a counter 14 is suspended in the inside and the sole mold 10 is arranged again in the condition that the last 13, the side mold 9, and the lower sole 5 are mounted thereon to define a clearance B 15. Liquid polyurethane resin for the upper sole 4 is injected in the clearance B 15 out of a pouring opening 18 provided at the heel side of the side mold 9 from the second injection molding machine to form the upper sole 4 and form the lower sole 5 and the counter 14 as a unit. In this way, injection molded shoes with a double-layer bottom 6 are completed. |
