The specific embodiment

Below in conjunction with specific embodiment the utility model is further specified.

A kind of helical gear mould; Comprise rush-upseat 1, go up diehead sheet 2, shapings go updash 3, go updash cover 4, be shaped inmould 5, be shaped thatnext dashes 6, next diehead sheet 7, next towardscover 8, nextred seat 9, shaping following twopunch 10, following twopunch pad 11, following twopunch cover 12, following twopunch seat 13, shapingplug 14,plug cover 15,mandrel holder 16; It is characterized in that being shaped going up and be pressed on the rush-upseat 1 towards covering 4 through last towards 3; Dash in theshaping 3 and rush-upseat 1 between be provided with diehead sheet 2; In the shapingmould 5 hollow space ecto-entads be followed successively by be shaped thatnext dashes 6, shaping following twopunch 10, shapingplug 14; Being shaped,next dashes 6 and dashes through next andcover 8 and be pressed on nextred seat 9, be shapednext dash 6 and nextred seat 9 between be provided with nextdie head sheet 7, shaping following twopunch 10 covers 12 through following two punch and is pressed on the following twopunch seat 13; Be provided with following twopunch pad 11 between shaping following twopunch 10 and the following twopunch seat 12, shapingplug 14 is fixed on themandrel holder 16 through plug lid 15.Dash 3 bottoms in the shaping inmould 5 inner chamber tops, the shaping corresponding skewed slot is arranged.Lastdie head sheet 2, nextdie head sheet 7, following twopunch pad 11 are provided with helicla flute.

During use; Only need to treat that the helical gear pressed compact of die casting puts on theshaping mould 5; Machine, on being shaped,dash 3, be shaped inmould 5, be shaped thatnext dashes 6, under the acting in conjunction of shaping following twopunch 10shaping plugs 14, just can with the helical gear pressed compact process need helical gear.

The utility model can produce special-purpose helical gear by a casting forming, and is simple in structure, easy to use.
