Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to shown in Fig. 1, a kind of gravity casting apparatus for cylinder head, including cover plate 1 and be arranged on described lid
Plate 1 top pour mouth 4, described cover plate 1 both sides are provided with fixture 14；Described fixture 14 sidewall bottom is provided with base plate 16, and
Base plate 16 and described cover plate 1 all fit tightly with described fixture 14 sidewall；Described fixture 14 surface is provided with and filters out pore
