Abstract: A second mold is divided into a recess-side mold portion, which includes a recess, and a remaining mold portion in a sliding direction of a movable pin, while a size of a gap between the recess-side mold portion and the remaining mold portion is adjustable. The second mold is configured to execute a first-mold-closing operation for contacting the recess-side mold portion to the first mold and thereafter a second-mold-closing operation for contacting the remaining mold portion to the recess-side mold portion. A distal end portion of the movable pin is configured to be placed into a non-contacting state, in which the distal end portion of the movable pin is not in contact with the workpiece, at a time of executing the first-mold-closing operation. The distal end portion of the movable pin is configured to contact the portion of the workpiece at a time of executing the second-mold-closing operation.

Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. Other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.

Abstract: A shutter device includes blades rotatable to interrupt an air flow therethrough, and first and second frames supporting the blades. One end of a blade in a longitudinal direction thereof includes a first support rotatably supported by the first frame, and a second support rotatably supported by the second frame. The first support and the second support are disposed along a widthwise direction of the blade. Another end of the blade in the longitudinal direction thereof includes a third support rotatably supported by the first frame, and a fourth support rotatably supported by the second frame. The third support and the fourth support are disposed along the widthwise direction of the blade.
