上海工具铸造厂造型工人,在毛主席革命路线指引下,在批林批孔运动普及、深入、持久开展的大好形势中,坚持自力更生,对机械化造型线上的Z145型造型机起模机构进行了革新。原来的起模机构是由二个起模油缸和同步机构等组成,生产一段时间后,各铰链配合处间隙增大了,致使油缸漏油严重,二缸磨擦力不同,因此起模同步性差,直接影响了起模质量,还浪费机油。
Under the guidance of Chairman Mao’s revolutionary line, styling workers at Shanghai Tool Foundry insisted on self-reliance in the popularization, deepening and sustained development of the motion of “approving Lin and Confucius holes”. The Z145-type modeling machine modeling mechanism on the mechanized molding line was carried out innovation. The original mold release mechanism is composed of two mold release cylinders and a synchronization mechanism. After a period of production, the clearances at the joints of the hinges increase, resulting in severe oil leakage and different friction between the two cylinders. Therefore, the mold synchronization is poor, Direct impact on the quality of the mold, but also a waste of oil.
