Description

Be suitable for the sectional die that the depositing diamond-like coating realizes that little forming process is lubricated
Technical field
The present invention relates to a kind of sectional die.
Background technology
The little shaping of plasticity is at least in the process of both direction less than the 1mm micro parts with plastic molding method forming dimension or characteristic size.Along with reducing of micro parts physical dimension, its specific area (surface area and volume ratio) increases sharply, and makes friction enlarge markedly the influence of little forming technology.At present, the little forming technology of plasticity mainly still adopts traditional liquid or solid lubricant lubricating method, has many deficiencies.Such as, when adopting fluid lubricant lubricated, because lubricant easily flows and the differentiation of component surface microscopic appearance, very easily overflow at the fringe region lubricant of mould and member contact-making surface and lose lubricant effect, and should the zone proportion along with the rapid increase that reduces of member physical dimension, cause reducing of The friction coefficient member physical dimension and enlarge markedly the dimensional effect that promptly rubs phenomenon.In addition, fluid lubricant is easily stressed and assemble in little shaping, forms the difficult dead band that is shaped, because the micro parts size is little, the influence in this zone is remarkable.And when adopting kollag lubricated, its particle size is in micron or sub-micrometer scale, and the forming accuracy of micro parts requires also in micron or sub-micrometer scale, makes little forming accuracy be difficult to control.From the wearing and tearing angle, the minisize mould size is little and stressed bigger, very easily weares and teares, and reduces die life, has influenced the uniformity of little drip molding.
Summary of the invention
The mold cavity size that the objective of the invention is in order to solve existing micro-drawing forming is very little, die cavity internal table surface roughness is difficult to guarantee simultaneously, very difficult at its surface deposition diamond-like coating, and be difficult to guarantee the problem of diamond-like coating performance, proposed a kind of sectional die that the depositing diamond-like coating realizes that little forming process is lubricated that is suitable for
The present invention solves the problems of the technologies described above the technical scheme of taking to be: described sectional die comprises upper bolster, cope match-plate pattern, stripper, lower bolster, die shoe, combined die, drift, drift spline piece, guide pillar, guide pin bushing, the spring and first screw, described upper bolster is positioned on the upper surface of cope match-plate pattern and both are affixed, described first screw passes cope match-plate pattern and is threaded with stripper, be provided with the spacing of 5-20mm between described cope match-plate pattern and the stripper, described drift is by head, one is made in middle part and bottom, wherein the head of drift is a cylinder, the cross section at middle part is circular, the bottom is a cuboid, the head of described drift is contained in the cope match-plate pattern, the lower end at the middle part of described drift and bottom all are contained in first endoporus that is provided with on the drift spline piece, described drift spline packaged in stripper and the major diameter end face and the stripper of drift spline piece affixed, described upper bolster and cope match-plate pattern are provided with the spring eye that is complementary, described spring is packed in the spring eye, the lower end of described spring is contained in the groove that the stripper upper surface is provided with, the top of described guide pillar is packed in the cope match-plate pattern, described lower bolster is arranged on the upper surface of die shoe and both are affixed, described stripper is arranged on the upper surface of lower bolster, described lower bolster and die shoe are provided with the guide pin bushing installing hole that is complementary, described guide pin bushing is packed in the guide pin bushing installing hole, described stripper is provided with and the corresponding through hole of the endoporus of guide pin bushing, the lower end of described guide pillar is passed through hole and is contained in the guide pin bushing and is slidingly matched with guide pin bushing, described combined die is contained in the lower bolster and is affixed with the bottom of lower bolster, described combined die is made of two axisymmetric half modules, each half module is made up of semicircle platform and semicolumn, the semicircle platform is arranged on the semicolumn and both make one, described two half modules are fixedly connected, described die cavity is located at the central axis position on combined die top, and the bottom and the die cavity of described drift are complementary.
The present invention has following beneficial effect: the combined die that the present invention adopts can be processed respectively, is convenient to miniature concave die cavity internal table mirror polish and handles, and obtains the required best bright finish surface of diamond-like coating deposition easily and is convenient to lubricate; When diamond-like coating deposits, combined die difference depositing diamond-like coating can be easy to guarantee the performance of diamond-like coating on the other hand; When size of formed part changes, only need to change combined die, drift and drift spline piece, other major parts then do not need change, can significantly reduce die manufacturing cost.
