The temperature of molten iron when being poured, molding sand quality influence, and surface quality of continuous castings is poor, and later period cleaning is difficult；
Because quality requirement needs to arrange more row in mo(u)ld top half face to can increase exhaust of the casting in casting process
Air tube keeps the cleaning workload in later period larger.
Therefore, it is necessary to a kind of new technical solutions to solve the above problems.
Summary of the invention
Goal of the invention: providing a kind of sand core group of vertical pouring, solves the problems, such as the positioning accuracy of sand core group core packet.
The present invention also provides a kind of pouring procedures, apply to solve vertical pouring in the problems in the sand core group.
Technical solution: in order to achieve the above objectives, following technical side can be used in the sand core group of vertical pouring provided by the invention
Case.
A kind of sand core group of vertical pouring, two core packets, upright casting device including anvil swage group, in anvil swage group；
The core packet includes several crankshaft cores being arranged side by side, the jacket core for accommodating crankshaft core, is mounted on crankshaft core and jacket core both ends
Two end cores, be mounted on two side cores of crankshaft core Yu jacket core two sides；Each crankshaft core, which is equipped with, runs through crankshaft core
Positional punch, and placed channel is collectively formed in the positional punch of each crankshaft core, runs through the positioning by a lock core screw rod
Channel is by several bent axis positionings；The upright casting device include upright casting road between two core packets, self-support running channel bottom to
The ingate of cross gate, connection cross gate and core packet bottom that two sides extend；Anvil swage group includes two accommodating chambers, described horizontal to pour
After road extends to core packet bottom and is connected to by ingate with core packet, each cross gate and corresponding core packet are located at corresponding one
In accommodating chamber.
The utility model has the advantages that in the present invention by lock core screw rod by several bent axis positionings and after forming crankshaft core group, it is subsequent right
The assembling of core packet passes through the crankshaft core self poisoning inside sand core group, other encirclements using the crankshaft core as positioning datum
The part of crankshaft core has had determined positioning datum and has assembled, and improves product size precision.And it is simple to organize core mode, improves
Production efficiency.
It further, further include nut corresponding with lock core screw rod, after the top of the lock core screw rod passes through placed channel,
It is fixed by the nut.
Further, the side in-core is equipped with oil duct core.
Further, the upright casting device further includes the satrain relief for being mounted on the core side of wrapping.
Following technical scheme can be used using the vertical pouring method of above-mentioned sand core group in the present invention:
Molten iron self-support running channel is introduced from top to bottom, molten iron enters cross gate, then from cross gate by ingate from lower
The upper type chamber entered and be full of core packet, extra molten iron are overflowed from satrain relief.
The beneficial effect of the vertical pouring method includes: occur thin-walled water jacket will not due to using rising pouring system
Sintering phenomenon；Discharge directions are single, keep exhaust Feeder Design simple, effectively improve product yield；The surface quality of casting is excellent,
Overlap is small, can effectively mitigate the cleaning workload in later period.
