A lower mold attachment plate (1), on the upper surface of which the fixed mold half (6) is attached, is fixed to a machine base. An upper mold attachment plate (2), to which the movable mold half (7) is attached in opposite to the fixed mold half (6), is movable upwardly and downwardly by mold moving cylinders (5, 5a). A rotary disc (3), which has plural injection cylinder insertion holes (3a) in the same circle in vertical alignment with plural injection cylinder insertion holes (2a) of the upper mold attachment plate (2), is rotatably pivoted on the upper surface of the upper mold attachment plate (2). Plural injection units (4) arranged over the rotary disc (3) in predetermined distances along the circle are joined with the rotary disc (3) as a unit. As the rotary disc (3) is rotated to a divided angular position, a slide fastener chain is conveyed along the extension of the chain travelling path, by a predetermined length at every injection molding by means of chain conveyer. <IMAGE> |
