Description
Technical field
The present invention relates to engine oil pump rotor technology of die manufacturing field, specially a kind of engine oil pump rotor shaping
Mould.
Background technology
Casting mould refers to, in order to obtain the planform of part, to make part with other materials being easily molded in advance
Planform, is then put into mould in sand mold again, and a sky as design of part size is then formed in sand mold
Chamber, then mobility liquid is poured into a mould in the cavity, can just be formed and mold shape structure complete after liquid cooling solidification
The part of sample.
But, traditional moulds are larger due to cast construction, so produced in stowing operation wrapping up in gas phenomenon, cause product to add
Occur stomata after work, main cause is that steam vent set location is not right, cause gas to discharge less effective, conventional cast mould is more
Steam vent is arranged on mold bottom, makes the gas inside some grooves be difficult to discharge.Conventional cast mould another drawback
It is and the mold exterior smoother because the size of mould junction manufacture is identical, it is relatively elaborate when causing form removal.
The content of the invention
It is an object of the invention to provide a kind of oil pump for engine rotor forming die, to solve to be carried in above-mentioned background technology
The problem for going out.
To achieve the above object, the present invention provides following technical scheme：A kind of oil pump for engine rotor forming die, including
Outer rotor die sleeve, outer rotor core rod, internal rotor die sleeve and internal rotor core rod, the outer rotor die sleeve bottom are fixedly connected with outer turning
Submodule block set, the outer rotor die sleeve seat both sides uniform screw thread is connected with four fixing bolts, the outer rotor die sleeve seat bottom
Outer rotor core rod seat is movably installed with by fixing bolt, the outer rotor core rod seat upper surface center is fixedly connected with outer rotor
Core rod；The internal rotor die sleeve bottom is fixedly connected with internal rotor die sleeve seat, and the internal rotor die sleeve seat both sides uniform screw thread connects
Four fixing bolts are connected to, the internal rotor die sleeve seat bottom is movably installed with internal rotor core rod seat by fixing bolt, described
Internal rotor core rod seat upper surface center is fixedly connected with internal rotor core rod.
Further, the outer rotor die sleeve and internal rotor die sleeve bottom interior wall groove bosom are fixedly installed exhaust
Hole.
Further, the outer rotor die sleeve is engaged with outer rotor core rod.
Further, the internal rotor die sleeve is engaged with internal rotor core rod.
Further, the unofficial biography submodule core print seat length is long more than outer rotor die sleeve seat length, and interior biography submodule core print seat
Degree is more than internal rotor die sleeve seat length.
Further, the outer rotor core rod has outer rotor casting gate, the internal rotor with outer rotor die sleeve middle setting
Core rod has internal rotor casting gate with internal rotor die sleeve middle setting.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, by the way that the whole mould of oil pump for engine rotor forming die to be split into the independent mould of several primary structural components, be conducive to
Prevent the cold burden during casting too fast, it is to avoid incomplete situation hair of casting occurs crackle or even in casting component out
It is raw.
2nd, because die sleeve seat is flexibly connected by fixing bolt and core rod seat, die sleeve can be tight with core rod when making casting
Close connection, prevents casting liquid from running mould, and when being easy to form removal, easily mold core is separated with mould set.
3rd, steam vent is fixedly installed by outer rotor die sleeve and internal rotor die sleeve bottom interior wall groove bosom, is had
The gas of groove depths is completely exhausted out beneficial to when being cast, is prevented from being produced in stowing operation and is wrapped up in gas phenomenon, led
There is stomata after causing Product processing.
4th, by unofficial biography submodule core print seat length more than outer rotor die sleeve seat length, and interior biography submodule core print seat length is more than in
Rotor die sleeve seat length, can allow user conveniently to have an effect, consequently facilitating the mould after the completion of casting is split to come.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-4 are referred to, the present invention provides a kind of technical scheme：A kind of oil pump for engine rotor forming die, including it is outer
Rotor die sleeve 4, outer rotor core rod 5, internal rotor die sleeve 10 and internal rotor core rod 12, the bottom of outer rotor die sleeve 4 are fixedly connected
There is outer rotor die sleeve seat 2,2 both sides uniform screw threads of the outer rotor die sleeve seat are connected with four fixing bolts 3, the outer rotor mould
