With the rapid development of machinery industry, today with the rapid development of plastic industry, injection molding machine both in quantity and variety on occupies an important position, so as to become the fastest growing in the plastic machinery, one of the largest number of models in production. Next by we teach people the sole injection molding machine maintenance and maintenance knowledge. Injection molding machine can have a molding complex, the size is accurate or texture is fine and close with a metal insert plastic products, widely used in national defense, electrical, automotive, transportation, building materials, packaging, agriculture, culture and education of health and People's Daily life. Injection molding process of all kinds of plastic processing and has good adaptability, high production capacity, and easy to realize automation. The star, the cloth of plastics processing enterprises in our country, all over the country, equipment technical level is uneven, most of the processing enterprises equipment requires technical transformation. Over the past few years, China's plastic machinery industry technical progress is very significant, especially in injection molding machine technology level gap with foreign brand products greatly narrowed, inside the control level, product quality and appearance modeling has achieved significant difference. Choose domestic equipment, with small investment, can also produce comparable to imported equipment quality products. These create conditions for enterprise's technical transformation. To strengthen the use of plastic machinery, the maintenance and management work, correct use and reasonable lubrication, maintenance, regular maintenance, planned maintenance, improve equipment intact rate, often make the equipment in good condition. Note: about the process of sole injection molding machine operation to improve the machine to form a good habit of sole injection molding machine operation life and production safety is of great benefit. Boot before: ( 1) To check whether there is water, oil into the electric control box, if be affected with damp be affected with damp, do not switch on. By maintenance personnel will be electrical parts should be dry again after boot. ( 2) Check whether the power supply voltage is in accordance with, the general should not exceed & plusmn; 15%. ( 3) Check the urgent stop switch, before and after the safety door switch is normal. Verify motor and oil pump rotation direction. ( 4) Check the cooling pipe was clear, and the oil cooler and barrel end of the cooling jacket into the water. ( 5) Check the activity parts for lubricating oil ( Fat) Add the lubricating oil, and. ( 6) Open the electric heating, heating tube paragraphs of the machine. When the temperature of the paragraphs is achieved, and then heat preservation for a period of time, so that the machine temperature to stabilize. Holding time according to the requirement of the different equipment and plastic raw materials. ( 7) Inside the hopper add sufficient enough plastic. According to different requirements of plastic injection molding, some raw materials best first after drying. ( 8) To cover the barrel on the insulation plate, so that we can save electricity, and can prolong the life of electric heating circle and current contactor. Operation: ( 1) Not for convenience, cancel the exit at will. ( 2) Observe the pressure oil temperature, oil temperature is not beyond the prescribed scope. Ideal working temperature of hydraulic oil should be kept between 45 ~ 50 ℃, generally within the scope of 35 ~ 60 ℃ is more appropriate. ( 3) Pay attention to adjust the travel limit switch, avoid machine in action during the impact. At the end of work: ( 1) Before downtime, clear plastic barrel inside, prevention of leftover material oxidation or long-term thermal decomposition. ( 2) Mould should be open, to toggle lever mechanism for a long time in the blocking state. ( 3) Must be equipped with lifting equipment in the workshop. Mould should be very careful about heavy components such as installation, in order to ensure production safety.
