Description
The present invention is a kind of centrifugal casting machine, and a plurality of workpiece of once casting simultaneously are specially adapted to the casting of micromotor stator, rotor, also can be used for the casting of various small-sized alloy components.
Centrifugal casting is that melt metal liquid is poured in the rotating die cavity, and molten metal is covered with die cavity and rotates thereupon under action of centrifugal force, and final set becomes foundry goods.The existing centrifugal casting workpiece of once can only casting exists inefficiency, and especially other than ring type spare is unsuitable for centrifugal casting.As micro-motor rotor, adopt pressure pouring or one centrifugal casting of a casting, often cause disconnected bar, pore etc. to influence the quality of product, and efficient is low.
Task of the present invention is a kind of centrifugal casting machine that once can a plurality of workpiece of centrifugal casting of design.This machine is by the power that drives main shaft, with the mould of main axis rotation, and backstop that cooperates with mould and hold-down mechanism, the elevating mechanisms of mould etc. are partly formed.Die cavity or internal mold that a plurality of workpiece of casting are arranged in mould, and make each die cavity or internal mold all be communicated with same cast gate, molten metal enters each die cavity or the internal mold through running channel from cast gate during cast, under action of centrifugal force, guarantees the workpiece moulding simultaneously in each die cavity or the internal mold.Jiao Zhu workpiece is solid like this, and quality is good, the qualification rate height; Operating efficiency is significantly improved; Also be applicable to the centrifugal casting of other than ring type spare.
Centrifugal casting machine of the present invention is made up of parts such as power, support, hydraulic transmission, casting mould and hoisting mechanisms.This machine main shaft can directly be driven by motor, or by gear, belt drives, and also the usable oils motor drives.As adopt oil motor to drive, can reach does not have the joint speed change.And oil motor can be arranged in the fuel tank, frame bottom plate is installed on the fuel tank.The alignment of shafts of casting machine has oilhole, one of oilhole links to each other with the oil pipe control valve by swivel coupling and connects oil pump, the oil cylinder of the overall shape cylinder body in the other end of oilhole, oil cylinder more than two or two is arranged in the dish type cylinder body, the oil cylinder number of elements equates with die cavity number of elements in the mould, each oil cylinder of dish type cylinder body can be processed by integral body, or is combined by each single oil cylinder.The dish type cylinder body is driven an oil groove at coaxial oilhole connecting place, by oil groove oil is injected each oil cylinder and promotes plunger motion.The plunger outer end heads on rocking arm; there is axis hole in the stage casing of rocking arm; axis hole departs from one; withstanding on the plunger of a head length; rocking arm is installed on the fixed disk by bindiny mechanism; fixed disk is made up of base plate and annulus, and rocking arm can be installed on the fixed disk annulus by bearing, pin, and the other end of rocking arm withstands on the block of die cavity in the mould.Mould is made up of upper die and lower die; patrix has a pouring basin; two or more die cavities are arranged in patrix and the counterdie; pouring basin communicates with each die cavity through running channel; there is block the die cavity outer end; also internal mold or core can be installed in die cavity, like this block can with internal mold or core group together, this moment, rocking arm withstood on the end cap of internal mold.As when casting rotor, rocking arm withstands on the end mould.Upper and lower mould and in backstay is arranged, backstay passes fixed disk and dish type cylinder body, on the counterdie ejector beam can be arranged, patrix install to promote cap, promotes the cap mesopore and connects cast gate, promotes cap top and connects pressing plate, is the horizontal Beam of lifting under the pressing plate; Process an annular convex shoulder as the periphery of patrix, on the horizontal Beam crotch is housed, utilize crotch to drive convex shoulder and promote patrix, so just without pressing plate.Horizontal Beam can be promoted by the mechanism that oil cylinder, piston, the piston rod of symmetry are formed; Also can pass through guide rail, screw rod, the lifting of tooth bar transverse arm.
Centrifugal casting machine of the present invention, a plurality of workpiece of once casting simultaneously make operating efficiency improve several times; This machine molten metal when work flows into various chamber in proper order, the workpiece of casting is very solid, and quality is good, during as the casting rotor, the molten metal turbulent flow and the solution that do not have to occur in the extrusion process enter phenomenons such as silicon steel sheet slit, thereby the electrical property of rotor is improved a lot; Also be suitable for the centrifugal casting of other than ring type spare simultaneously, applied range; Easy to operate, alleviated labour intensity.
