Patent ID: 7635258

Claim:
A device for filling casting gaps during manufacture of an assembly, comprising: a mounting to securely hold the assembly in a position that, while the casting gaps are filled with a crosslinkable casting compound that contains a filler, permits air to escape from the casting gaps, in dependence upon a filling rate, through an opening in an assembly housing during filling; at least one supply line, for the crosslinkable casting compound, that opens into the casting gaps; at least one supply container for the crosslinkable casting compound; an arrangement for exerting pressure on the crosslinkable casting compound such that the crosslinkable casting compound passes through the at least one supply line; a nozzle; at least one hollow needle, for supply, the nozzle being connected to the at least one supply container for the crosslinkable casting compound and opening into the assembly; at least another hollow needle for filling; and a branching between a discharge from the at least one supply container and the at least one hollow needle and the at least another hollow needle, the branching including an outlet for each of the at least one hollow needle and the at least another hollow needle, each outlet ending in a respective other nozzle on each of which one of the at least one hollow needle and the at least another hollow needle is placed; wherein: the mounting is formed from a base plate, a tensioning bar, and at least one component to fix the tensioning bar in a predetermined location and position with respect to the base plate; the arrangement includes at least one compressor; the at least one hollow needle is guided into the assembly through the opening in the assembly housing and opens into one of the casting gaps; the at least one hollow needle is sensor-controlled and motor-driven; the housing encloses a piezoactuator; and the at least one hollow needle is: displaceable, together with the branching and the nozzle at an ending of the outlet, in the casting gaps in a direction of filling and in a direction opposite to the direction of filling; and pulled upward as the filling progresses.
