Internal rotor casting gate is provided among core rod and internal rotor die sleeve.
Compared with prior art, the beneficial effects of the utility model are：
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, have
Beneficial to preventing that cold burden is too fast during casting, avoid the component of casting out cracked or even the incomplete situation of casting
Occur.
2nd, because die sleeve seat is flexibly connected by fixing bolt with core rod seat, die sleeve seat and core rod seat are tight when enabling casting
When close connection, preventing liquid race mould of casting, and be easy to form removal, easily mold core and mould set are separated.
3rd, by being fixedly installed steam vent in outer rotor die sleeve and internal rotor die sleeve bottom interior wall groove bosom, have
The gas of groove depths is completely exhausted out beneficial to when being cast, prevents from producing in stowing operation and wraps up in gas phenomenon, lead
There is stomata after causing Product processing.
4th, outer rotor die sleeve seat length, and internal rotor core rod seat length are more than more than interior by outer rotor core rod seat length
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.
