Lubrication and maintenance
To ensure normal operation of the injection molding machine, all moving parts of the machine are equipped with lubricating devices and lubricating points (refer to schematic diagram of lubrication). Especially for the mold clamping mechanism, this machine uses the automatic lubricating system incorporating oil steel jackets. The following is the brief introduction of the automatic lubricating system.
Configuration and features of the lubricating system
The lubricating system consists of lubricant oil pump, lubricant oil circuit, lubricant oil distributors and lubrication points (including oil gaskets). Lubricant oil runs to all oil circuit distributors via the oil pump and then to all lubrication points (including oil gaskets) to accomplish the function of lubricating all moving parts of the plastic injector. As it incorporates oil steel gaskets, the system is able to store oil and thus offers good and durable lubrication effect.
The lubricating system is controlled by the computer. Via monitoring the pressure relay by computer, the lubrication conditions of the system can be controlled. During lubrication, if the oil tank is short of oil, the oil circuit leaks, the pump filtering screen clogs or oil pressure is not high enough, the control computer will sound an alarm to indicate a poor lubrication condition. In such case, check the cause for poor lubrication and timely add lubricant oil or repair to ensure normal lubrication and operation of the plastic injector.
Requirements for lubricant oil
The lubricant oils recommended for use in this system, refer to the types of lubricant oils shown in the schematic diagram.
