Abstract
PURPOSE:To obtain a molded product superior in an external appearance, by a method wherein a gate for molten resin is provided on the center of one end wall of the molded product of a cylindrical body, the same is once molded into a form of an uncompleted molded product not having an opening part on the one end wall with an injection molding method and then the title molded product is formed by striking out the opening part. CONSTITUTION:At the time of mold clamping, a nozzle of an injection molding machine is brought into contact with a sprue bushing 16 and molten thermoplastic elastomer resin is cast into a mold cavity part formed of female split molds 15A, 15B, a core 21 and a core insertion piece 27 under appropriate conditions. A form of a molded product IC in this instance is not in such a form where an end wall possesses the opening parts A, B like a final molded product, a gate 17 can be provided on the center part of the end wall 4. With this construction, a continuous molten resin flow where a weld line part does not generate can be obtained. After the resin injection into a mold cavity has been cooled and solidified, an injection mold is broken. When the molded product IC is shifted to a movable side under a state where the molded product IC is attached to the core 21, the same is separated from the female split molds 15A, 15B at the same time. The opening parts A, B are opened at necessary positions of the end wall 4 to the molded product IC released from the mold and a molded product 1A or 1B is obtained.
