一、前言湿型造型所用的具有代表性的造型机中,有震压式造型机,借助于震实的撞击力和压实的压缩力来紧实型砂。但是,震实与压实的配合大多是凭经验求得的,因此就会出现因模板形状和型砂种类不同而造成砂型质量不佳现象。因此,对这种造型机的研究,必须考虑到对铸型有很大影响的模板的形状和型砂的性质,需要研究的因素很多,可是,除了千千岩等人的一部份关于震实、压实的研究外,几乎别无他有。
First, the foreword Wet modeling used in the representative molding machine, there are vibration-type molding machine, with the help of the shock force and the compaction compaction compaction to compact sand. However, most of the compaction between compaction and compaction is obtained empirically, so that the quality of the sand pattern may be poor due to the different shapes of the template and the types of the sand. Therefore, the molding machine research, we must take into account the shape of the template has a great impact on the mold and the nature of the sand, there are many factors that need to be studied, but, in addition to Chiaki Yan et al. , Compaction research, almost no other.
