Summary of the invention
The purpose of this utility model is exactly the deficiency in order to solve prior art and a kind of Mold Making of providing is simple, reliable in structure, low-pressure casting hub die ring ejecting structure easy for installation.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of low-pressure casting hub die ring ejecting structure, comprise oil cylinder connector, the push rod pressing plate of mould, mandrel plate, mould joint pin and be set in the guide pin bushing outside mould joint pin, push rod pressing plate is arranged on mandrel plate, guide pin bushing is through push rod pressing plate and mandrel plate, it is characterized in that, on described push rod pressing plate, be connected with and eject connecting plate, oil cylinder connector and eject connecting plate and be connected and fixed by least two symmetrical fan-shaped Joining clasps of installing, fan-shaped Joining clasp is fastened on push rod pressing plate.
As further illustrating of such scheme, described oil cylinder connector and eject connecting plate ring-type laminating, its faying face diameter is 150-250 millimeter, makes mandrel plate stress equalization in the time ejecting.
Described fan-shaped Joining clasp inner side is provided with draw-in groove, and oil cylinder connector is provided with protruding position with the sidepiece that ejects connecting plate, and cylinder connector coordinates with described draw-in groove is concavo-convex after mutually combining with the protruding position that ejects connecting plate.
The draw-in groove of described fan-shaped Joining clasp is designed to inclined-plane with the joint face of described protruding position and coordinates.
Described fan-shaped Joining clasp is fixed on push rod pressing plate by external snap ring handle.
Described snap ring handle comprises the bending location division that extend top pressure arm and pressure arm rear end, top, and top pressure arm horizontal-top is pressed on the sidepiece of fan-shaped Joining clasp, and bending location division is fixed on push rod pressing plate or mandrel plate by securing member.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopts the faying face size that adds large tank connector and eject connecting plate, is increased to diameter 150-250 millimeter by 75 millimeters of diameters, is modified into ring-type laminating by a contact, makes mandrel plate stress equalization in the time ejecting.
2, oil cylinder connector of the present utility model with eject being connected of connecting plate, adopt the symmetrical fan-shaped Joining clasp of installing to connect, joint face is designed to inclined-plane and coordinates, Joining clasp is fixed on push rod pressing plate by snap ring handle, what ensure to connect is reliable, stable.And eliminated the fit clearance of connector, be easy for installation and removal again, due to ring ejecting structure make mould eject with reseting procedure in stressed evenly, substantially eliminated and ejected casting deformation and reset stuck phenomenon.
