Abstract
PURPOSE: To obtain waterstops which are easy to transport because a runner keeps a plurality of them in connection and are easy to cut off because of its thin gates by a method wherein a synthetic resin is injected from a runner groove into a plurality of waterstop molding cavities through a plurality of gate grooves having small cross-sectional areas.
CONSTITUTION: A metal mold A for waterstops comprises a runner groove 1, gate grooves 2 smaller in cross-sectional as area than the runner groove 1, waterstop molding cavities 3, etc. A resin is flowed from the nozzle of an injection molding machine into the runner groove 1 of the mold A, and injected from the runner groove 1 into the waterstop molding cavities 3 through the gate grooves 2, whereby waterstops 6 are molded at the ends of a runner 4, in connection with the runner 4 through gates 5 which are smaller in cross-sectional area than the runner 4. The thus produced products are packaged and transported in the condition where two waterstops 6 are coupled by the runner 4, and the waterstops 6 are separated from the runner 4 by cutting the gates 5 before use.
