The safety of used injection molding machines is very important

The safety of used injection molding machines is very important. When the mold clamping mechanism opens and closes the mold, the reliability of the low pressure protection system of the injection molding machine involves the safety of man and machine.

Used injection molding machines must implement a combined electrical, mechanical, and hydraulic safety protection system. This protection mainly reflects two aspects: one is the safety protection of the mold, and the other is the safety protection of the person. Before closing the mold, when the safety door is not closed, the mold closing should not be able to move; in the process of closing the mold, if the safety door is not closed to the correct position, the template action stops or the mold opens automatically. If, during mold closing, foreign objects such as inserts fall into the cavity due to vibration, or other foreign objects are mistakenly inserted into the mold, the mold should stop the mold closing action, or automatically open the mold and give an alarm .

Another safety aspect of the injection molding machine is to prevent cold start of the pre-plastic screw. When the material of the screw does not reach the specified temperature and holding time, it is prohibited to start, otherwise an alarm will occur.

A Used injection molding machine nozzle splash protection device is necessary to prevent burns. The key points for purchasing a Used injection molding machine are to have a high degree of automation, complete functions and high production efficiency. Modern Used injection molding machines can be operated manually, semi-automatically, and fully automatically. As long as the mold design is reasonable, the fully automatic operation from injection molding to ejection and drop of the product can be achieved, and it can also be equipped with a robot to achieve unmanned operation. The insert core function, hydraulic nozzle control function and fast heating runner probe function can all be programmed into the automatic program in the injection molding cycle for automatic circulation. High production efficiency is mainly manifested in the short molding cycle of each molded product under normal injection molding process conditions. This reflects the comprehensive performance indicators of a Used injection molding machine's mechanical, electrical, and hydraulic systems. Therefore, high-quality hydraulic and electronic components and sophisticated manufacturing techniques must be used to improve the sensitivity and repeat accuracy of the Used injection molding machine system. This is a reliable guarantee for the efficient operation of the injection molding system.

The key points of injection molding machine are energy-saving and environmental protection, which can not be ignored when judging modern Used injection molding machines. Energy saving mainly reflects the water-saving and power-saving capabilities of Used injection molding machines compared with similar machines under normal process conditions when the power drive system, heating system, and heat dissipation system meet the normal process conditions. The design of modern Used injection molding machines should fully consider the theme of "environmental protection".

Used injection molding machines should prevent hydraulic oil leakage or excessive noise, and work quietly. In addition, the injection molding machine itself should also use more environmentally friendly materials. The main points of the injection molding machine must be convenient for machine maintenance and overhaul. The installation position of various machines such as mechanical, hydraulic, electronic, and electrical components should be conducive to the maintenance and repair of the machine. At the same time, the generalization and standardization of Used injection molding machines are also very important to users.
