我厂是生产塑料机械专业厂,生产多种型号注塑机。其中SZ—125B注塑机于1982年开始设计,1983年试制成功,84年起批量生产。该机每次注射量可达170g、注塑成型面积可达430cm~2,能一次成型外形复杂,尺寸精确或带有嵌件的塑料制件,对各种塑料加工的适应性强,生产效率高。合模、整体移动、注射、预塑及制品顶出等动作均采用液压传动(图1所示)。与电器配合能可靠地实现自动或半自动工作循环,功率匹配合理。由图1可知,采用双联泵供油,多级压力控制,螺杆用液压马达驱动、能无级变速。经多年来生产厂使用,
Our factory is specialized in producing plastic machinery factory, producing a variety of models of injection molding machine. One SZ-125B injection molding machine design in 1982, 1983 trial success, 84 years of mass production. The injection volume per machine up to 170g, injection molding area up to 430cm ~ 2, can shape a complex shape, precision or with plastic parts, plastic processing of a variety of adaptability, high production efficiency . The clamping, the overall movement, the injection, the pre-molding and the ejection of the product are all driven by a hydraulic drive (Figure 1). With electrical appliances can be reliably achieved automatically or semi-automatic work cycle, the power to match the reasonable. As can be seen from Figure 1, the use of double pump oil supply, multi-stage pressure control, screw driven by a hydraulic motor, continuously variable speed. After years of production plant use,
