Sand mold is the second sand mold；
Step 7: the first sand mold and the second sand mold surrounding back-up sand and being increased into fixation respectively, molten aluminum is poured, casts lid respectively
Case mold and stripping pattern blank；
Step 8: processing through-hole 0.5mm bigger than the inducer mould outlet cylinder diameter of axle at stripping pattern blank center, then add
The stripping pattern gap of three spiral guide vane of work, put later inducer mold and constantly modify stripping pattern gap, enable inducer mold from
It is screwed out just below stripping pattern blank, obtains stripping pattern template；
Step 9: top box mold and stripping pattern template being combined, and with brill sandbox location hole；
Step 10: process support frame fixes stripping pattern template；
Step 11: coaxially fixing a connecting shaft on inducer mould outlet cylinder, the inducer mold of tape spool is set
In in stripping pattern template, making inducer mold and stripping pattern template curved surface tangent；Guideway is mounted on company below stripping pattern template
In spindle, and keep guideway and stripping pattern template relatively fixed by axle sleeve fixed plate；Finally coaxially installed additional in connecting shaft outer end
Swingle.
Further preferred embodiment, a kind of simple preparation side of the equidistant inducer casting stripping pattern mold of three leaves spiral
Method, it is characterised in that: in step 1, for inducer mold compared to inducer design size amplification 1%, inducer exports column part
Lengthen 30mm.
