第四步：电热平板48工作预设时间之后，断开电源停止工作；
第五步：左侧向移动机构4和右侧向移动机构12同步工作，分别带动左芯盒3向左、右芯盒1向右移动，直至左芯盒3和右芯盒1均脱离砂芯2；
第六步：抽取驱动动力11工作，经推抽板10、芯棒座9向下拉动芯棒8，使得芯棒8顶部的芯头85脱离砂芯2，并且芯棒8顶部芯头85的顶端高度低于托板7的底面高度，如图6所示；
第七步：将托板7与机座6之间的紧固件松下，施力于托板7，使得托板7沿着机座6顶部的凹槽移动并最终脱离凹槽，在此过程中，砂芯2随着托板7移动；
第八步：在机座6的凹槽内放置另一个托板7，并通过紧固件固装；重复第一步至第七步，进行下一循环的砂芯2制造。
本发明实现了一次成型多个相同或不相同的砂芯，大大提升了工作效率，并降低了人工强度，保证了成型精度和成型质量。
以上描述是对本发明的解释，不是对发明的限定，本发明所限定的范围参见权利要求，在本发明的保护范围之内，可以作任何形式的修改。
