A kind of above-mentioned bevel housing sprue core and rising head core mold, the rising head die cavity and sprue mould
Chamber, which is connected with, penetrates Sha Kou.
A kind of above-mentioned bevel housing sprue core and rising head core mold, the rising head cavity quantity are four
Individual, sprue cavity quantity is two.
The beneficial effects of the utility model are：Heating tube heats to rising head die cavity and sprue die cavity, and mold temperature reaches
After design temperature, check that air pressure meter reading is normal, start coremaking, upper and lower mould matched moulds, both sides sand-shooting head compaction mold, compression sky
Gas injects the precoated sand in the sand hopper of both sides in the die cavity of mould by penetrating sand mouth, and precoated sand solidifies in die material, solidification
Terminate automatic die sinking, core is ejected by push rod, core is taken out, starts next group of coremaking operation, due to final drive casing
The rising head and sprue shape of body are inconsistent, and according to the shape of rising head core and sprue core, the bottom of rising head die cavity is provided with
Two symmetrical arc grooves, rising head mandrel tip are provided with flange corresponding with arc groove, and sprue die cavity is with the first circle
Shape chamber and the second circular cavity, the bore of the second circular cavity are more than the bore of the first circular cavity, manufactured rising head core and sprue
The link position intensity of core is higher, and corresponding rising head casting and sprue casting also increase intensity, rational in infrastructure.
