Embodiment
As shown in Figures 1 to 9: one kind provided by the utility model can increase the die-casting forming die of hole strength in product,
Including dynamic model 01 and cover half 02, the dynamic model 01 is equipped with movable model chamber 011, and the cover half 02, which is equipped with, determines model cavity 021, moves
Movable model chamber 011 constitutes product type chamber 04 compatible with product 03 to be cast with model cavity 021 is determined when mould 01 is molded with cover half 02,
It is equipped with type core 05 compatible with 03 inner hole 031 of product to be cast in the product type chamber 04, the inside of the type core 05 is along its axis
Line direction is equipped with interior cinder ladle 06, and the height H2 ratio of the height H1 of interior cinder ladle 06 and product inner hole 031 to be cast is 2:3~1:1.
When being used for the die casting of the product with inner hole structure using die-casting forming die described in the utility model:
It is axially mounted in type core 05 in the position mount type core 05 of corresponding 03 inner hole 031 of product to be cast of product type chamber 04
Interior cinder ladle 06 injects feed liquid in product type chamber 04, and in casting process, the interior cinder ladle 06 of setting can timely and effectively be produced mold
Raw gas discharge, while can also timely and effectively collect the cold burden generated in mold to interior cinder ladle 06, to effectively keep away
Exempt from the defects of generating stomata, cinder hole at casting inner hole, can effectively enhance the intensity of casting inner hole, guarantee the quality requirements of casting；
In addition, in the utility model, the inside of type core 05 is to be equipped with interior cinder ladle 06 along its axis direction, and interior cinder ladle 06
The height H2 ratio of height H1 and product inner hole 031 to be cast is 2:3~1:1, and therefore, interior cinder ladle 06 described in the utility model is
Be the equal of perpendicular cinder ladle, and in conventional die casting mold cinder ladle setting, usually on the exhaust duct of setting mold, major function
It is the effect of exhaust, it is faint to the collecting effect of cold burden；Although cinder ladle is located at casting inner hole in addition, also having at present,
Current mold is the cinder ladle in the orifice position setting thin layer of casting inner hole, and this cinder ladle can be called for flat cinder ladle,
Cold burden and gas are to collect, be discharged from the aperture of casting inner hole by flat cinder ladle, and the flat cinder ladle of this setting is difficult mould adequately
The defects of cold burden and gas in tool are effectively collected, are discharged, and still have cinder hole, stomata in the casting hole wall produced, intensity
It does not reach requirement, and erects the setting of cinder ladle in the utility model, allow the side wall quilt of cold burden and gas from casting inner hole yet
Perpendicular cinder ladle is collected, is discharged, more significant to the collection of cold burden and gas, discharge effect for traditional flat cinder ladle, raw
The defects of not having cinder hole, stomata in the casting hole wall of output, interior hole strength can reach even beyond requirement.
As a preferred solution:
The sectional area ratio of the sectional area of interior cinder ladle 06 and product inner hole 031 to be cast is not less than 1:4, further, interior cinder ladle
