摘要： Continuous injection molding apparatus for slide fastener chains. According to a preferred embodiment, this apparatus comprises single stationary mold (1) and two movable molds (2, 3). The stationary mold (1) is provided with a sprue (15) contacted with a nozzle (18) of an injection cylinder (9). These three molds are disposed so that the opposed parting planes (32-35) of the three molds are parallel each other. Then, the sprue (15) is communicated with each row of cavities (4), through each runner (14) or through each runner and each path. The fastener tapes (5) are transported intermittently in spaces formed between the molds respectively in a longitudinal direction. The molten material is shot from the injection cylinder to the sprue (15) and is injected into the rows of cavities (4) between two molds of these three molds through the runner (14) or through the runner and the path respectively. Then, the pairs of rows of fastener elements (6) are molded from the molten material in the rows of cavities (4) and attached simultaneously to the beaded edges. As a result, the plural number of slide fastener chains can be produced by one-shot injection with this apparatus having a normal area of longitudinal cross section.
