Abstract

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 a closed integral wax pattern die cavity matched with a to-be-formed integral wax pattern in shape. The valve cover wax pattern integral forming die can realize integral forming of the valve cover casting wax pattern and the dead head wax pattern.

Description

technical field [0001] The invention relates to the field of wax mold manufacturing, in particular to an integral forming mold of a valve cover wax mold, which belongs to the technical field of precision casting. Background technique [0002] Cast steel valve is a common precision parts, including valve core and valve cover. At present, the valve cover is generally cast and formed by investment casting process. [0003] combined reference figure 1 As shown, the investment casting process of the valve cover in the prior art is roughly as follows: [0004] (1), at first provide bonnet casting wax pattern mold and riser wax pattern mold, wherein: bonnet casting wax pattern mold has the mold cavity that matches with the shape of bonnet wax pattern 200 to be formed, riser wax pattern mold Then there is a mold cavity matching the shape of the riser wax mold 100 to be formed; [0005] (2) Inject molten wax material into the cavities of the bonnet casting wax mold and the riser ...
