The plastic composite material molded structure includes a molded main body including a composite material molding source molded into a predetermined shape by a press mold, a boss portion protruding from the molded main body, and an injection member made of a plastic material, the injection member being inserted and fixed in the boss portion by a mold pin and having an undercut disposed to be fastened to the fastening member.
Claims20
A plastic composite material molded structure configured to be fastened to a correlated component by a fastening member, the plastic composite material molded structure comprising:
- a molded main body comprising a composite material molding source molded into a predetermined shape by a press mold;
- a boss portion protruding from the molded main body;
- and
- an injection member comprising a plastic material, the injection member being inserted and fixed in the boss portion by a mold pin and having an undercut disposed to be fastened to the fastening member.
A method of forming a plastic composite material molded structure to be fastened to a correlated component by a fastening member, the method comprising:
- injecting a composite material molding source into a lower mold of a press mold, wherein the composite material molding source is a gel material;
- molding a molded main body and a boss portion on an upper surface of the molded main body by pressing an upper mold of the press mold to the lower mold and flowing the composite material molding source, wherein a mold pin is disposed on a lower surface of the upper mold and an injection member comprising a plastic material is secured to the mold pin, wherein the injection member is inserted into the boss portion by the molding, and wherein the injection member comprises an undercut that receives the fastening member;
- and
- removing the upper mold from the lower mold, wherein the mold pin is separated from the injection member by the removing.
