| 1、手动或半自动塑料注射成型机的润滑 1, manual or semi-automatic plastic injection moulding machine lubrication ① 齿轮变速箱的润滑 变速箱的任何故障都将影响到加工的质量和数量。箱内经淬硬处理的正齿轮和调质轴应保证均匀可靠的润滑油膜，一般采用油杯和飞溅法即可满足润滑要求。 The lubrication of gear transmission gearbox of any failure will affect the machining quality and the quantity. Box via a spur gear hardening and tempering shaft shall ensure that the oil film of uniform and reliable, general lubrication oil cup and splash method can meet the requirements. ② 注射部件的润滑 注射部件的作用是经电加热圈，使塑料受热均匀达到注射温度，由压料杆螺旋加压形成注射压力。压料杆的润滑一般采用油杯、油绳等润滑方法。 (2) the injection parts lubrication of injection parts is used by the electric heating circle, even make plastic is heated to the injection temperature, the material rod screw pressure injection pressure formed by pressure. Pressure of rod lubrication oil lubrication oil cup, wick and other commonly used methods. ③ 锁模部份的润滑 锁模部件由带轮、丝杆、螺母、虎钳等组成。其中因丝杆、螺母摩擦结点较小，油膜容易被挤裂，要求润滑油应具有较好的油性，常采用 L-AN46全损耗系统用油或L-HL液压油通过油杯、油绳进行润滑。 (3) clamping part of the lubrication clamping parts by pulley, screw, nut, vice, etc. By screw, nut friction nodes is small, the oil film are easy to be cracked, lubricating oil should be has good oil, often using L - AN46 total loss system oil or L - HL hydraulic oil through the oil cup, wick lubrication. ④ 机座部分的润滑 机座上的滑动导轨一般用铸铁制成。因导轨承受的负荷及滑动速度都不大，矿物型润滑油就可保证一定的边界油膜。 (4) base on the part of the lubricating base sliding guide generally made from cast iron. Because of guide rail under load and sliding speed is not large, the boundary of the mineral lubricating oil can guarantee the oil film. 2、自动液压注塑机的润滑 2 hydraulic injection molding machine, automatic lubrication 这种注塑机的特点是：自动化程度高、性能稳定、并有电气、液压联锁保护装置，精度高、结构较复杂。 This kind of injection molding machine features are: high degree of automation, stable performance, electric, hydraulic, interlock protection device, high precision and complicated structure. ① 注射部分的润滑。 由於这部份是完成注射双液压缸拉动预塑变速齿轮箱，经齿轮箱推动螺杆，将均匀塑化的塑料射入模腔内，实行注射成型的关键部件。运动比较频繁，又有电加热装冱，必须严格执行润滑制度。本部份有如下四个主要润滑部位： 1) injection parts of lubrication. Because this part is to achieve double hydraulic cylinder drive pre plastic injection speed gear box, the gear box drive screw, will even plasticizing plastic into the mold cavity, implement of the key parts in injection molding. Sports are frequent, and electric heating Hu, must strictly enforce the lubrication system. This section has the following four main lubrication part: 注射座与机架导轨、齿轮箱底部导轨、变速齿轮箱内都可加用L-HL或抗磨液压油，回转中心加相应润滑脂。 Injection of a gear and rack guide rail, guide rail, at the bottom of change gear box can be added with L - or HL anti-wear hydraulic oil, add grease corresponding rotary center. ② 移模部件的润滑 移模采用液压动力，选用直压式充液装置，结构简单，动作可靠，润滑点少。主要是保证在四根导柱上形成润滑油膜，也可用L-HL或高于L-HL的液压油，通过油杯、油绳润滑。 (2) move mould parts of the lubrication move mould adopts hydraulic power, use direct pressure type liquid device, simple structure, reliable operation, less lubrication points. Mainly is to ensure that in the lubricating oil film is formed on the four guide pillar, also can use L - or higher than L HL - HL hydraulic oil, through oil cup, wick lubrication. |
