Step 7.: move and penetrate sand device by penetrating sand mobile device and make to penetrate penetrating Sha Kou (71) and penetrating sand plate (3) and be connected of sand device (7), sand plate (3) is penetrated in unlatching, and by penetrating sand plate (3), sandbox (1), right sandbox (2) spray into molding sand left; Move and penetrate sand device by penetrating sand mobile device and make to penetrate penetrating Sha Kou (71) and penetrating sand plate (3) and be separated of sand device (7), close and penetrate sand plate (3);
Step 8: close high-pressure air source (81), opens venting valve (614), the pressing plate (607) under the effect of extension spring in two bulkhead sides grid (611) mutually away from and be close to the side of dividing plate;
Step: 9: hydraulic jack (601) fuel feeding, promotes two stripper plates (602) move toward one another one segment distance, completes the making to sand mo(u)ld;
Step 10: hydraulic jack (601), left sandbox (1), right sandbox (2) reset, takes out sand mo(u)ld, changes the making that match plate (4) enters next sand mo(u)ld, so repeats.
