The invention relates to a self-penetrate metal mould and relative production, wherein it uses metal powder, via passive stress, to prepare the blank with through hole; then sinters the blank to obtain the penetrated metal block; using mechanical machining or electric machining to make the metal block into the penetrate metal mould section chamber; combines the section chamber with other elements to obtain the molding mould. The inventive self-penetrate metal mould can be used to mould the liquid material that needs to exhaust the gas of mould chamber, that molding macromolecule material, molding plastic, etc. And it has simple process, low cost and wider application. |
