Description
Technical field
The utility model relates to a kind of powder metallurgy Coinjection molding apparatus of processing structure complex part.
Background technology
Powder metallurgy is the Workpiece shaping technology of carrying out sintering after placing mould by compression moulding metal dust again, and it has efficiently, the advantage of high-quality, precision, low energy consumption, has become a kind of Work piece processing method of alternative conventional cast moulding gradually.
General powder metallurgy die is the mode that adopts compacting mostly, make metal powder material rapid shaping in mould, carry out sintering then, this mould only can be used in the comparatively metal works of standard of processing structure, for some baroque miniature workpieces, because the structure of mold cavity wall is comparatively complicated, when mould bears big pressure, the mold cavity wall produces deformation, thereby causes workpiece and design size after the moulding there are differences, certainly, in order to overcome this defective, also can improve the intensity of mould, but the change of mould strength must increase the input cost of equipment.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of powder metallurgy Coinjection molding apparatus of processing structure complex part, and it is not needing to change under the prerequisite of mould strength, improves Products Quality.
For achieving the above object, the utility model adopts following technical scheme:
The powder metallurgy Coinjection molding apparatus of processing structure complex part, comprise, solid plate, be fixed on the guide pillar on the solid plate, the movable moving platen that is socketed on the guide pillar, be used for driving the hydraulic cylinder that moving platen slides along guide pillar, injection tube, the charging ram of movable cross-under in the tube chamber of injection tube, be used for to drive the motor that charging ram moves in the tube chamber of injection tube, a molding fixedly is arranged on the solid plate, injection tube is provided with one and the hopper of its chamber conducting, the front end of injection tube is equipped with a nozzle, and this nozzle is with the tube chamber of injection tube and the die cavity conducting on the shaping mould.
The tube cavity wall of injection tube offers internal thread, offers the external screw thread that mates with internal thread on the charging ram, and charging ram is connected in the rotating shaft of motor synchronously by a shaft coupling.
The outer wall of injection tube is provided with spiral helicine groove, is equipped with heater strip in this groove.
The beneficial effects of the utility model are:
Than prior art, the utility model adopts injection molding mode metal powder material to be pushed in the die cavity of mould, in the process of moulding, do not need to adopt the high speed drift to suppress, mould need not to bear bigger impulsive force, also just avoid die cavity wall generation deformation, improved Products Quality.
