Abstract
In a method and an apparatus for manufacturing chips for a thixomolding-process injection molding machine, primary crushed pieces obtained by fragmenting and crushing metal alloy wastes are cut and fragmented by a chip manufacturing apparatus having fixed blades, rotating blades, and a screen so as to obtain chips, with the result that the surfaces are polished, and a powder is eliminated by forced exhaust air, thereby making it possible to manufacture the chips while preventing ignition and explosion.
Claims12
A method for manufacturing chips for a thixomolding-process injection molding machine, comprising the steps of:
- charging primary crushed pieces, which are obtained by fragmenting and crushing wastes produced at the time of molding a metal alloy as well as wastes of metal alloy products, into a chip manufacturing apparatus having fixed blades, rotating blades, and a screen;
- cutting and fragmenting the primary crushed pieces by said fixed blades and said rotating blades, and passing the cut and fragmented pieces through and flying outside said screen so as to obtain chips;
- and
- forcedly exhausting a powder mixed with the chips.
An apparatus for manufacturing chips for thixomolding-process injection molding machine, comprising:
- fixed blades and rotating blades provided inside a chamber for cutting and fragmenting into chips primary crushed pieces of material fed into said chamber;
- a mesh-like screen provided in a side portion of said chamber;
- a chip takeout port provided on an outer side of said screen;
- a powder exhaust port for separately exhausting powder initially mixed with the primary crushed pieces;
- and
- a collector for collecting the chips made from the primary crushed pieces fed into said chamber and which have passed through the screen;
- cooling vanes provided above said rotating blades;
- and
- a coarse surface plate provided on a bottom portion of said chamber.
