Sprue is placed on the hole of hole cross gate sand core, sprue is blocked using mackintosh up and down, and running gate system entire so is just located
In closed state, running gate system can be entered to avoid sand, then starts quicksand moulding；After molding sand hardening, in sprue
Upper placement and fixed sprue cup, are waited to be cast；Top surface aperture cross gate sand core, the general cross gate sand core, cross of the utility model
The cross gate of running channel end sand core three parts composition may be implemented the length variation of cross gate, adapt to the production of more casting, and
Cross gate can connect the sprue and ingate of different-diameter, and the variation of different proportion running gate system may be implemented, and adapt to more
The production of casting；The utility model is combined by sprue, cross gate, ingate and is formed, and inside is cavity, can increase iron liquid stream
Dynamic speed, reduces pouring temperature；To sum up the utility model can realize that evaporative pattern casting filling velocity is fast and steady, ingate influent stream
Point is more, and ingate molten iron flow speed is slow, prevents pouring molten iron from returning and chokes, and then reduces cast(ing) surface dreg defect, improves casting
Surface quality, while 10-20 DEG C is reduced than prior art evaporative pattern pouring temperature, avoid the wasting of resources.
