顶板漏模及顶杆继升器车床四爪卡盘过去用型芯生产,现在在Z145造型机上搞出顶板漏模及顶杆继升器,解决了无法采用吊砂的困难。顶板和起模机构是同步动作的,托着吊砂。这是武汉重型机床厂铸锻件分厂的革新。〔摘自《铸造》1966 NO.6 几种简易造型设备沈阳空气压缩机配厂自行没计制造了三种简易设备: 1.带漏模板的简易震实造型机; 2.带有顶砂活块的漏模机; Roof leak-proof and mandrel lift lathe Four-jaw chuck used in the past core production, Z145 molding machine is now out of the roof leak-proof and mandrel lift, to solve the difficulties can not be used sand. Roof and the lifting mechanism is synchronized action, care sand hanging. This is the Wuhan Heavy Machine Tool Plant casting forgings innovation. 〔From “Casting” 1966 NO.6 several simple modeling equipment Shenyang air compressor with its own factory did not account for the manufacture of three simple equipment: 1. With a simple template shock modeling machine; 2. With sand top block Leaky mold machine;
