Valve cover wax pattern integral forming die

The invention provides a valve cover wax pattern integral forming die which is used for realizing integral wax pattern forming. An internal wax pattern comprises a dead head wax pattern part and at least one valve cover casting wax pattern part integrally formed on the dead head wax pattern part; the valve cover wax pattern integral forming die comprises the followings: an upper die cavity is formed in the inner surface of an upper die and comprises upper dead head die cavity parts communicating with each other and at least one upper valve cover die cavity part connected onto the upper dead head die cavity parts; and a lower die cavity matched with the upper die cavity is formed in the internal surface of a lower die and comprises low dead head die cavity parts communicating with each other and at least one lower valve cover die cavity part connected onto the lower dead head die cavity parts. When the upper die and the lower die are assembled, the upper die cavity and the lower die cavity are buckled to form
