Abstract
The utility model relates to a structure of loosing core of aluminum alloy wheel low pressure casting mould side forms, loose core the structure by core rack, gear, pull rod rack, spring, guide pin bushing, side forms inlay the cover and spacing connecting pin constitute, the rack core constitute by two parts, one of them part is the rack, another part must not be greater than 13 of spoke cross -section for its sectional area of core of spoke. Spacing connecting pin be used for the spacing connection between the mould of a template and top, the displacement of more than or equal to pull rod rack is wanted to spacing distance. The side forms mechanism of loosing core, its characterized in that, the surface processes circular shoulder hole respectively about the side forms, installs the guide pin bushing in the shoulder hole of its lower surface, above that installation spring and pull rod rack in the shoulder hole on surface for the lower extreme of pull rod rack is installed in the guide pin bushing. Utilize the gear to drive the structure of loosing core that the spoke was realized to pull rod rack and core rack simultaneously afterwards.
Description
Technical field
The utility model relates to aluminum-alloy wheel casting field, is specifically the pulled core structure of a kind of aluminum-alloy wheel low pressure casting limit mould.
Background technology
The most common manufacture method of existing aluminum-alloy wheel is low pressure casting, and low pressure casting is poured into by the metal of thawing in metal mold cavity and is solidified as blank, then become final finished product through machined sequence and coating process.Along with aluminum-alloy wheel market competition is more and more fierce, high strength, light-weighted wheel pursuing more and more by market.But now a lot of aluminum-alloy wheel manufacturer utilizes finite element analysis software to carry out Computer Aided Design to go out comparatively Rational structure and carry out weight reduction, thus reaches high strength, light-weighted requirement.So, each manufacturer in high strength and lightweight on reach again an equalization point, each product weight difference is very little, neither one new breakthrough.
Utility model content
The purpose of this utility model: in order to overcome above-mentioned the deficiencies in the prior art, propose the pulled core structure of a kind of low-pressure casting die of aluminium alloy wheel limit mould, make the spoke of automotive hub become hollow shape, not only lightweight, further increase the intensity of spoke, breach existing production technology.
The technical solution of the utility model: the pulled core structure of a kind of low-pressure casting die of aluminium alloy wheel limit mould, it is characterized in that, described pulled core structure is made up of core tooth bar (5), gear (6), pull bar tooth bar (3), spring (7), guide pin bushing (2), limit mould insert (4) and spacing connecting pin (9).
Described limit mould pulled core structure, it is characterized in that, on limit, mould upper and lower surface processes circular shape hole respectively, mounting guide sleeve (2) in the shoulder hole of its lower surface, mounting spring (7) and pull bar tooth bar (3) in shoulder hole surperficial thereon, and make the lower end of pull bar tooth bar (3) be arranged in guide pin bushing (2), when pull bar moves up and down, guide pin bushing (2) plays the effect of guiding.Recycle gear (6) subsequently drives pull bar tooth bar (3) and core tooth bar (5) to realize the process of loosing core of spoke simultaneously.
Described limit mould insert (4) coordinates with limit mould (1), and installs core tooth bar (5) in it, its objective is: wear and tear when core tooth bar (5) moves repeatedly limit mould (1) body, and mounting edge mould insert (4) can better edge protection mould (1) body.
Described core tooth bar (5) is made up of two parts, and wherein a part is tooth bar, has coordinated gearing with gear (6); Another part is the core of wheel spoke, and its sectional area is less than and equals 1/3 of spoke sectional area, its material selection H13 surface carbonation, strengthens corrosion resistance.Two parts bolt column connects, and its objective is: spoke type core segment contacts with aluminium liquid, is easier to corrosion, and with bolts can being convenient to is changed.
Described spacing connecting pin (9) is for spacing connection between top template (8) and backform (10), and spacing distance is greater than the displacement equaling pull bar tooth bar (3).
Advantage of the present utility model: this pulled core structure is simple, easy for installation, can cast out the wheel of hollow spoke, not only can alleviate wheel weight, can also improve the intensity of spoke, makes it to become high strength, light-weighted novel aluminum alloy casting wheel.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is further illustrated.
Fig. 1, Fig. 2 and Fig. 3 are the pulled core structures of a kind of aluminum-alloy wheel low pressure casting limit mould, be made up of core tooth bar (5), gear (6), pull bar these (3), spring (7), guide pin bushing (2), limit mould insert (4) and spacing connecting pin (9), described limit mould insert (4) coordinates in it with limit mould (1) installs core tooth bar (5).Described core tooth bar (5) is made up of two parts, and a part is tooth bar, has coordinated gearing with tooth axle; Another part is the core of spoke, its sectional area is less than and equals 1/3 of spoke sectional area, two parts are connected by bolt, and described spacing connecting pin (9) is for spacing connection between top template (8) and backform (10), and spacing distance is greater than the displacement equaling pull bar tooth bar (3).
Described limit mould pulled core structure, on limit, mould upper and lower surface processes circular shape hole respectively, mounting guide sleeve (2) in the shoulder hole of its lower surface, mounting spring (7) and pull bar tooth bar (3) in shoulder hole surperficial thereon, make the lower end of pull bar tooth bar (3) be arranged in guide pin bushing (2).
Be described further during 1 pair of the utility model matched moulds by reference to the accompanying drawings: when the die is closed, first close limit mould, now at spring (7) place in a free state, core tooth bar (5) does not extend into die cavity in limit mould (1).When top template (8) whereabouts matched moulds, top template (8) is pressed on pull bar tooth bar (3), pull bar tooth bar (3) moves down along with the whereabouts of top template (8), driven gear (6) is rotated counterclockwise, meanwhile gear (6) drives again core tooth bar (5) to move obliquely, makes core stretch into die cavity.Aluminum liquid filling type, forms the aluminum-alloy wheel of hollow spoke.
The die sinking of 2 pairs of the utility model is described further by reference to the accompanying drawings: when a die sinking, backform (10) is motionless, top template (8) moves to the upper limit position of spacing connecting pin, spring (7) recovers elastic force drive pull bar tooth bar (3) moves, gear (6) turns clockwise, drive core tooth bar (5) to move obliquely, make core extract foundry goods out.Drive limit mould (1) oil cylinder again, pull open limit mould (1).
3 pairs of the utility model twice-die-openings are described further by reference to the accompanying drawings, and when twice-die-opening, top template (8) drives on backform (10) and moves, foundry goods be also attached on backform along with on move, backform ejecting mechanism stretches out and ejects foundry goods, completes a productive temp.
