Fishing lure injection molding using additive manufacturing
View Patent ↗A molding device for producing thermoplastic articles and its method of use, wherein the molding device comprises a rigid bottom plate, a rigid top plate adapted to be removably coupled to the said bottom plate, a 3D-printed die or insert in the shape of half of the said article removably inserted into a CNC milled mold cavity. The molten thermoplastic material is injected in to the molding device through an injection port to form the thermoplastic in the shape of 3D-printed die or insert, wherein the thermoplastic article is a fishing lure.
1. A molding device for producing thermoplastic articles, comprising:
a rigid bottom plate;
a rigid top plate adapted to be removably coupled to said bottom plate, the rigid top plate having a void that forms a tail end of a fishing lure;
at least one CNC milled mold cavity partially extending within a thickness of the rigid top plate;
at least one 3D-printed die in the shape of a body and head of a fishing lure, the at least one 3D-printed die is configured to fit within the CNC milled mold cavity such that the body and the head are in communication with the tail end;
a plurality of fastening screws that removably secure the at least one 3D-printed die to the at least one CNC milled mold cavity;
at least one injection port for injecting a thermoplastic material into the said 3D-printed die;
wherein the fishing lure is removed from the molding device after a curing process.
