Abstract
The invention discloses a forming die. The forming die comprises a lower metal die, an upper metal die and micro protrusions, wherein the micro protrusions are located on the inner surface of the lower metal die and the upper metal die; the micro protrusions are columnar, the diameters of the micro protrusions range from 200 micrometers to 800 micrometers, and the distance between every two micro protrusions ranges from 100 micrometers to 400 micrometers; super-micro protrusions are arranged on the upper surfaces of the micro protrusions; the super-micro protrusions are columnar, the diameter of each super-micro protrusion ranges from 50 micrometers to 200 micrometers, and the distance between every two super-micro protrusions on the same micro protrusion ranges from 50 micrometers to 150 micrometers. Space among the super-micro is filled with gap air. In a metal forming process, under the combined action of metal surface tension and the micro gas air, gaps among the super-micro protrusions will not be filled with liquid metal, smooth surface structures are formed, and therefore products made through the forming die have the smooth surfaces, low roughness and low grinding cost; meanwhile, the sand hole defect and other defects will not be caused.

Preferably, the height of micro-protrusions is 200～800 μ m.
Preferably, the height of micro-protrusions be less than the metal counterdie thickness 1/1000.
Preferably, micro-protrusions is uniformly distributed in the inner surface of metal counterdie.
Preferably, the height of superminiature projection is 1/4～3～3/4 of micro-protrusions height.
Preferably, the superminiature projection is uniformly distributed in the upper surface of micro-protrusions.
Preferably, superminiature projection circular array is uniformly distributed in the upper surface of micro-protrusions.
Preferably, the internal cavities that metal counterdie and metal patrix form is the cavity that holds spherical structure.
Preferably, 100～200 times of the thickness that the diameter of cavity is the metal counterdie; The thickness of metal counterdie equates with the thickness of metal patrix.
Preferably, the diameter of cavity is 4～16mm.
Beneficial effect of the present invention is: a kind of mould, comprise metal counterdie, metal patrix and micro-protrusions, and micro-protrusions is positioned at the inner surface of metal counterdie and metal patrix; Micro-protrusions is column, and the diameter of micro-protrusions is 200～800 μ m, and micro-protrusions distance each other is 100～400 μ m; The upper surface of micro-protrusions is provided with the superminiature projection; The superminiature projection is column, and the diameter of superminiature projection is 50～200 μ m, and the distance each other of the superminiature projection on same micro-protrusions is 50～150 μ m.Be space between each micro-protrusions, between each superminiature projection, be full of gap gas; In Metal Forming Process, under the acting in conjunction of metal surface tension and miniature clearance air, the fluidised form metal can not filled the gap between the superminiature projection, but become round and smooth surface texture, the product that this mould is made, smooth surface, roughness is low, grinds cost low; Can not produce the defects such as trachoma simultaneously.
