J1113A卧式冷室压铸机系六十年代末七十年代初的产品,结构和性能相对较先进,但存在一些致命的弱点,即:从新机使用一年左右时间,产生压力系统压力不能稳定,升压很慢;漏油严重;油温过高,以致不能满足压铸工艺要求。有时,只能在0.39～0.49MPa压力情况下压铸,压出的铸件产生严重花斑、冷隔等压铸缺陷,成品率很低。有时,无法正常生产。针对这种情况,我们对J1113A型压铸机的动力源——油泵,进行了改进,将原来的双级叶片泵改用为轴向柱塞泵。轴向柱塞泵采用上海高压油泵厂产品,型号为:63MCY14—1B(定量)或63SCY14—1B(手动变量)。规格是:额定压力,31.5MPa;理论排量,63.9mL/r;1000r/min的公称流量,63L/min;公称速
J1113A Horizontal Cold Chamber Die Casting Machine The products in the late 1960s and early 1970s are relatively advanced in structure and performance, but there are some fatal weaknesses, that is, the pressure generated by the new machine during one year or so can not be stabilized , Boost slowly; serious oil spills; oil temperature is too high, so that can not meet the requirements of die-casting process. Sometimes, only 0.39 ~ 0.49MPa pressure die casting, casting out of a serious piebald, cold and other die-casting defects, the yield is very low. Sometimes, can not be normal production. In response to this situation, we J1113A die-casting machine power source - oil pump, has been improved, the original two-stage vane pump to axial piston pump. Axial piston pump using high-pressure pump factory in Shanghai products, models: 63MCY14-1B (quantitative) or 63SCY14-1B (manual variables). Specifications are: rated pressure, 31.5MPa; theoretical displacement, 63.9mL / r; nominal flow of 1000r / min, 63L / min; nominal speed
