PURPOSE: To easily and accurately stop a mold without complicating the structure of a mold clamping device by arranging a first injection device for injecting a resin of a first layer and a second injection device for injecting a resin of a second layer on both sides of a slide member in a reciprocally slidable manner. CONSTITUTION: Two mold clamping devices 11a, 11b have upper movable plates 13a, 13b moved up and down by rams 12a, 12b and are provided on the fixed plate 14 of a base stand 14a side by side in a horizontal direction. Upper molds 15a, 15b are attached to the upper movable plates 13a, 13b. Two upper molds 15a, 15b are composed of male molds having molding surfaces same in shape and the slide member member 21 forming an injection mold along with lower mold 16a, 16b, 16c allows three lower molds 16a, 16b, 16c attached to the upper surface thereof at the interval equal to that between the upper molds 15a, 15b to reciprocally slide along the row of the upper molds 15a, 15b. The slide member 21 is provided on the fixed plate 14 under the upper movable plates 13a, 13b in a reciprocally slidable manner. |
