Article manufacturing method and manufacturing apparatus

An article manufacturing method comprising:

• molding a first product by closing a first mold onto a second mold and an intermediate mold, the intermediate mold being provided between the first mold and the second mold;
• injecting molten resin from at least one injection unit provided at the first mold into a first mold insert of the first mold;
• joining the first product to a second molded product at the second mold:
• separating a first plate including the first mold insert from the first mold as the first, second and intermediate molds are opened;
• and
• moving the first mold insert to a position where the first product and the second molded product face each other.

A manufacturing apparatus, comprising:

• a first mold provided with an injection unit configured to inject molten resin;
• a second mold configured to close together with the first mold to perform molding using molten resin;
• and
• a mold insert provided at the first mold, to which the molten resin is injected from the injection unit, wherein
• the first mold includes a plate that spaces the mold insert away from the injection unit, and
• the plate is configured to move the mold insert away from the injection unit.
