近30年来,由于各种新的有机和无机粘结剂的相继出现,造型方法在不断革新,自硬型的普及和湿粘土砂高压造型的推广,把砂型技术推向新的高度。然而砂型造型技术上仍存在急待解决的问题:一是机械化的高效造型与低效制芯、下芯之间的矛盾;二是现行的干芯工艺中的粉尘、噪音和有害气体等污染环境,损害操作者的健康。垂直分型的湿粘土砂芯工艺就是 In the past 30 years, due to the successive appearance of various new organic and inorganic binders, the modeling methods have been continuously updated, the popularization of self-hardening type and the popularization of high pressure molding of wet clay sand pushed the sand technology to new heights. However, there is still an urgent need to solve the problem of sand molding technology: First, the mechanization of the efficient modeling and inefficient system core, under the core of the contradiction between; Second, the existing dry core process of dust, noise and harmful gases and other polluting environment , Undermining the operator’s health. Vertical type of wet clay sand core craft is
