Abstract
The invention relates to a demoulding device of a motor rotor aluminum casting machine, which comprises a die assembly oil cylinder, wherein a piston rod is arranged in the die assembly oil cylinder, a through hole is formed in the piston rod, and a demoulding ejector rod capable of moving up and down in the through hole of the piston rod is arranged in the through hole. On the premise of ensuring the demolding effect and the working efficiency, the invention simplifies the structure of the device, reduces the volume of the whole machine and greatly reduces the whole manufacturing cost of the device.
Description
Technical field
The present invention relates to a kind of cast aluminium device of rotor, be specifically related to behind a kind of electric motor rotor aluminium casting device the rotor demoulding.
Background technology
The cast aluminium of China's rotor adopts the pressure aluminum process mostly at present.Because lack the professional die casting equipment that is fit to electric motor rotor aluminium casting special process condition, producer adopts common hydraulic press to reequip or purchase the cast aluminium that common cold-chamber die casting machine is used for rotor more.The structure of common die casting machine is mostly in the middle of die cylinder and injection oil cylinder, also has a dynamic model planker, after foundry goods forms in mold cavity, foundry goods is taken out in die sinking immediately, but also had a process of deviating from from mould before taking off, making foundry goods deviate from what work in the process at this is exactly ejecting mechanism, and ejecting mechanism is arranged in the dynamic model planker more on common die casting machine, therefore machine volume is bigger, and production cost is higher.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, designed and developed out that the die casting machine complete machine structure is simplified greatly, production cost is the stripper apparatus of the electric motor rotor aluminium casting machine of corresponding reduction also.
The present invention is achieved by the following technical solutions:
A kind of stripper apparatus of electric motor rotor aluminium casting machine includes die cylinder, and a piston rod is arranged in the die cylinder, is provided with a through hole in the described piston rod, is provided with can be in a piston rod through hole up and down demoulding push rod in the through hole.
A kind of stripper apparatus of electric motor rotor aluminium casting machine, the longitudinal cross-section shape of described through hole and demoulding push rod are inverted " protruding " font, the shape of demoulding push rod and through hole cooperatively interact and demoulding push rod the upper half diameter greater than the diameter of half under the through hole.
A kind of stripper apparatus of electric motor rotor aluminium casting machine is provided with multiple-sealed circle on the mating surface of described demoulding push rod and through hole, to prevent pressing oil to leak from the piston rod through hole.
The present invention makes hollow shape with the piston rod of die cylinder, with the setting of demoulding push rod wherein.During die casting, the die cylinder piston rod is together descending together with demoulding push rod, and knockout pin is run into cast aluminium earlier and promptly stopped descendingly with axle, and that piston rod still continues is descending, till matched moulds.Like this, demoulding push rod is with respect to the piston rod segment distance that moved up.After motor rotor die-casting is good, the die cylinder piston rod i.e. upwards backhaul, the rotor that die casting is good can move upward together with dynamic model, backhaul at the end, it is stop motion that demoulding push rod is at first run into the oil cylinder loam cake, and piston rod still continues to move upward, like this, demoulding push rod has just moved down a segment distance with respect to piston rod, and this of demoulding push rod just moves can eject compression mod by the rotor that die casting is good, thereby has finished demoulding action.The present invention is owing to be arranged on ejecting mechanism the inside of die cylinder piston rod, thereby saved the dynamic model planker, made like this under the prerequisite of stripping result and operating efficiency assurance, simplified the structure of this device, machine volume diminishes, and the whole manufacturing cost of device also greatly reduces.Be provided with multiple-sealed circle on the mating surface of demoulding push rod and through hole, to prevent pressing oil to leak from the piston rod through hole.
Description of drawings
Accompanying drawing 1 is an electric motor rotor aluminium casting machine stripper apparatus off position sectional structure schematic diagram.
Accompanying drawing 2 is the descending die casting state of an electric motor rotor aluminium casting machine stripper apparatus sectional structure schematic diagram.
Accompanying drawing 3 is the up and demoulding state sectional structure schematic diagram of electric motor rotor aluminium casting machine stripper apparatus.
The specific embodiment
Referring to shown in Figure 1.
The present invention includes die cylinder 4, a piston rod 1 has been arranged in the die cylinder 4, be provided with a through hole in the piston rod 1, be provided with can be in a piston rod through hole up and down demoulding push rod 2 in the through hole.The longitudinal cross-section shape of through hole and demoulding push rod 2 is inverted " protruding " font, the shape of demoulding push rod 2 and through hole cooperatively interact and demoulding push rod 2 the upper half diameters greater than the diameter of half under the through hole, be provided with multiple-sealed circle 5 on the mating surface of demoulding push rod 2 and through hole, to prevent pressing oil to leak from the piston rod through hole.During work referring to shown in Figure 2, die cylinder 4 inner piston rods 1 together with demoulding push rod 2 one descending, demoulding push rod 2 is run into cast-aluminum motor rotor 3 earlier and is promptly stopped descending, and that piston rod 1 still continues is descending, till matched moulds, like this, demoulding push rod 2 is with respect to piston rod 1 segment distance that moved up.After cast-aluminum motor rotor 3 die casting are good, referring to shown in Figure 3, piston rod 1 in the die cylinder 4 i.e. upwards backhaul, the cast-aluminum motor rotor 3 that die casting is good can move upward together with dynamic model, backhaul at the end, it is stop motion that the oil cylinder loam cake is at first run in demoulding push rod 2 upper ends, and piston rod 1 still continues to move upward, like this, demoulding push rod 2 has just moved down a segment distance with respect to piston rod 1, this of demoulding push rod 2 move just can die casting is good cast-aluminum motor rotor 3 eject compression mod, thereby finished demoulding action.
