Further, the swing width of the swing is preferably about 30 to 20 O mm.
- the number of collisions per unit time between the impact applying material and the inner surface of the hollow object is ensured by appropriately setting the moving range of the impact applying material at the time. If the swing width is less than 30 mm, the number of collisions between the impact imparting material and the inner surface of the hollow object is not secured, and sand is not quickly and sufficiently removed by the impact generated by the collision, which is not preferable. Further, even when the swing width is larger than 200 mm, the number of collisions between the impact applying material and the inner surface of the hollow object does not increase, only the time during which the impact applying material is in contact with the inner surface of the hollow object is increased. However, the sand is not easily removed.
- the total swing time of the swing is preferably about 1 to 120 minutes. This is to ensure the total number of collisions between the impact imparting material and the inner surface of the hollow object. If the total swing time is less than 1 minute, the total number of collisions between the impact imparting material and the inner surface of the hollow object is not secured, and the sand on the inner surface of the hollow object may not be sufficiently removed, which is not preferable. In addition, depending on other conditions, the total swing time is about 120 minutes and the sand is completely removed, so even if the rock is shaken longer than that, the effect on the time required for manufacturing hollow objects is improved. Not so good.
- the direction in which the hollow objects are rocked so that the number of collisions between the impact applying material and the inner surface of the hollow objects is ensured.
- the direction may be determined by the shape of the hollow part of the hollow object. For example, when the intake manifold 140 shown in FIG. 1 is rocked, it is not preferable to rock the intake manifold 140 in the longitudinal direction of the hollow portion 144 of the intake manifold 140. This is because the ratio of the impact imparting material having a longer moving distance in the hollow portion 146 is increased, and the number of collisions between the impact imparting material due to the swing and the inner surface of the hollow object is reduced.
- the preferred swing direction when swinging intake manifold 140 is, for example, the direction indicated by arrow R shown in FIG. It is also preferable to change the direction during rocking.
