注塑机是塑料机械行业中常用的机械设备。它是将热塑性塑料或热固性塑料利用塑料成型模具制成各种形状的塑料制品的主要成型设备。分为立式、卧式、全电式。注塑机能加热塑料，对熔融塑料施加高压，使其射出而充满模具型腔。
Injection molding machine is a commonly used mechanical equipment in the plastic machinery industry. It is the main molding equipment that makes thermoplastic or thermosetting plastic into plastic products of various shapes by using plastic molding molds. It is divided into vertical, horizontal and all electric type. Injection molding functions to heat plastics, apply high pressure to molten plastics, and make them shoot out and fill mold cavity.
维修工作者首先必须了解和掌握塑料机械注塑机的操作说明书中的内容，熟悉和掌握注塑机的机械部件、电路及油路，了解注塑机在正常工作时机械、电路及油路的工作过程，了解和掌握电气元器件、液压元器件的检查和维修使用方法。清楚正常工作状态与不正常工作状态，以避免费时的误判断和误拆卸。
Maintenance workers must first understand and master the contents of the operating instructions of the plastic mechanical injection molding machine, familiar with and master the mechanical parts, circuits and oil circuits of the injection molding machine, understand the working process of the machinery, circuits and oil circuits in the normal operation of the injection molding machine, and understand and master the inspection and maintenance of electrical and hydraulic components. Usage method. Clear normal working condition and abnormal working state to avoid wrong judgement and misoperation of free time.
维修工作必须了解设备的操作方法及要有一些注塑成型基础知识，并且会正确使用注塑机。若不知道操作注塑机，检修工作是非常困难的，判断故障也可能不可靠。注塑机中电路板及电气元器件长期受高温、环境、时间等因素影响，器件工作点偏移，元器件的老化程度，都是属于正常范围。所以，调试注塑机也是维修工作中必不可少的基本功之一。
Maintenance work must understand the operation of the equipment and some basic knowledge of injection molding, and the correct use of injection molding machine. If you do not know the operation of injection molding machine, maintenance work is very difficult, and it may not be reliable to judge faults. The PCB and electrical components of injection molding machine are affected by high temperature, environment and time for a long time. The working point of the device is offset and the aging degree of the components is within the normal range. Therefore, debugging the injection molding machine is also one of the essential skills in maintenance work.
了解注塑机的工作程序，调试注塑机电子电路、液压油路是十分重要的环节。
Understanding the working procedure of injection molding machine, debugging the electronic circuit and hydraulic oil circuit of injection molding machine is very important.
维修工作要做到准确、可靠和及时，必须对各类型注塑机的使用说明书中内容加以研究和掌握，一般维修过程中，维修思路通常是电路、油路和机械部件动作。而调校工作又反过来进行，如机械动作和锁模压力等，可去找油路和电路，如电路输出正常，则调校油路阀。若油路正常工作则调校电路电子板。当然最后统调，但三者关系相互依赖、相互控制。
In order to achieve accurate, reliable and timely maintenance work, it is necessary to study and grasp the contents of the instructions for the use of various types of injection molding machines. The adjustment work is carried out in turn, such as mechanical action and mode locking pressure, can go to find the oil circuit and circuit, if the circuit output is normal, then adjust the oil valve. If the oil circuit works normally, adjust the electronic circuit board. Of course, final unification, but the three relations depend on each other and control each other.
正确使用仪器仪表、调校检测电路，检修油路，调试机械部分的位置及动作，是判断故障的重要手段。
Correct use of instrumentation, adjusting detection circuit, overhauling oil circuit, adjusting the position and action of mechanical parts are important means to judge the fault.
一般注塑机生产厂家只给出设备的电气方框图、油路的方框图和机械的主要部分，这对于维修工作是不够的。必须注意日常维护工作中，收集、整理各方面的有关资料。如电气、电子、机械备件、油路、电磁阀体等方面的资料。
General injection molding machine manufacturers only give the electrical block diagram of equipment, the block diagram of oil circuit and the main parts of machinery, which is not enough for maintenance work. Attention must be paid to collecting and arranging all relevant information in routine maintenance work. Such as electrical, electronic, mechanical spare parts, oil circuit, electromagnetic valve body and other information.
例如电气方面若有机会就要测绘电路原理图，测绘电子板的原理图及实际的接线图，测出接线端子对应的器件等有关资料，以使在维修中为故障的判断和分析提供准确的检测点去向。
For example, if there is an opportunity in the electrical field, it is necessary to survey and map the circuit schematic diagram, the schematic diagram of the electronic board and the actual wiring diagram, and the corresponding devices of the wiring terminals and other relevant information, so as to provide accurate detection points for fault diagnosis and analysis in maintenance.
测出其检测点的具体参数。在必要的时候，还要自己制作电源，模拟输入和输出信号，进行模拟测试或调校，以掌握和取得第一手维修资料数据，如各级工作点油路维修也是如此，必须根据油路及油压电磁阀的特点综合调校和维修。
The specific parameters of the detection points are measured. When necessary, they should also make their own power supply, analog input and output signals, analog testing or adjustment, in order to master and obtain first-hand maintenance data, such as all levels of working point oil line maintenance is also the case, must be based on the characteristics of oil line and oil piezoelectric solenoid valve comprehensive adjustment and maintenance.
有机会要经常拆卸、清洗、检查、安装电磁阀。这些处理会造成许多麻烦，但却是至关重要的。
Opportunity to remove, clean, inspect and install solenoid valves frequently. These treatments can cause a lot of trouble, but they are very important.
维修工作必须掌握和整理出符合原理、符合逻辑系统故障维修方法和判断程序图，在结合平日维修工作实际，收集注塑机有关资料，如故障进行处理，其方法有逐步检查法、模拟检查法、电压测试法、通断测试法、电路板替代法等各种方法。
Maintenance work must grasp and sort out the maintenance methods and judgment program diagrams which accord with the principle and logic system fault. In combination with the daily maintenance practice, the relevant data of injection molding machine should be collected, such as fault handling. The methods include step-by-step inspection, analog inspection, voltage testing, on-off testing and circuit board substitution. Methods and so on.
通过修理后，要重新调整工作点，重新进行调校，进行带负载试验，使其设备工作在操作说明书所列数据的参数范围内。
After repairing, the working point should be readjusted, adjusted again, and the load test should be carried out to make the equipment work in the parameter range of the data listed in the operation instructions.
