Abstract
An injection molding tool and method are used to create a connection between at least two metal parts. The metal parts are inserted into the injection molding tool. Using a clinching device of the injection molding tool, the metal parts are mechanically connected to one another by clinching and are encapsulated with a plastic material using an extruder connected to the injection molding tool so as to, at least partially, enclose the metal parts with overmolding or casting.
Claims13
A method for producing a connection between at least two metal parts, the method comprising:
- inserting the at least two metal parts into an injection molding tool;
- mechanically clinching, via a clinching device of the injection molding tool, the at least two metal parts such that the at least two metal parts are connected to each other;
- and
- encapsulating, via an extruder connected to the injection molding tool, the at least two metal parts with a plastic material to at least partially envelop the at least two metal parts with a casting.
An injection molding tool for producing a connection between at least two metal parts, the injection molding tool comprising:
- an assembly device configured to mechanically connect the at least two metal parts within the injection molding tool;
- and
- at least one mold cavity configured to form an overmolding around the connected at least two metal parts.
