Problems solved by technology

[0007] However, in the technique of Patent Document 1, there is a space for the resin material to flow in the mold, so it may be difficult to shape the shape intended for the prepreg (insert part)
In such a case, if injection molding is performed after shaping, twisted parts tend to occur on the prepreg, making it difficult to form a uniform resin layer.
In addition, in the techniques of Patent Documents 2 and 3, it is necessary to shape the prepreg in advance and process it into a preform, so there is a problem that it takes time to produce the molded product.

Abstract

The invention discloses a method for manufacturing a molded article, a molded article, and a device for manufacturing the molded article. An insert member (100) heated by a heating device (13) is conveyed into a die (51) by a conveyance device (12). The insert material (100) is then shaped in the die (51) in a state in which the die (51) is a minute distance open. A molding material (91) is injected into the die (51) and pressed while the die (51) a minute distance open is closed, and a molded article (80) including the insert member (100) is thereby molded.

Description

technical field [0001] The present invention relates to a method for manufacturing a molded article, a molded article manufactured by such a method for manufacturing a molded article, and a manufacturing apparatus for a molded article. Background technique [0002] In the past, there has been known a technique in which a sheet-like material heated by a heating device and in a softened state is inserted into a mold of a mold clamping device installed in a molding device to shape it, and then injection molding is performed (for example, see Patent Document 1). [0003] In addition, conventionally, there is known a technique of inserting a previously shaped preform into a mold of a mold clamping device installed in a molding device, and then performing injection molding by compression molding or by using a movable core. In injection molding in which the core retreats, the entire surface of a previously shaped preform is covered with a resin layer (for example, refer to Patent ...
