| The manipulator moves back and forth every day, especially the special manipulator of injection molding machine moves up and down twice a cycle, and the speed of up and down in the mold is very fast. If the buffer fails, the pneumatic actuator has no shock-absorbing function when the reciprocating motion stops, which causes the vibration of the special manipulator of the injection molding machine. Most of the connection parts of the special manipulator of injection molding machine are fixed by screws. Because of the long-term vibration, the screws become loose, which will definitely cause the spreader of the special manipulator of injection molding machine and the connection block of the components to break. Due to the vibration of the special manipulator of the injection molding machine, the loose connection of the electric wire and the loose connection of the relay cause the bad contact of the electric circuit. Causes the injection molding machine special manipulator disorderly movement, the electronic control to die, Burns out the electronic control and so on phenomenon. 1. Hydraulic buffering: This type of accessory is guaranteed by the supplier one year or 1.5 million times and must be replaced regularly. 2, pneumatic components: Simple, multi-functional manipulator all the action depends on the gas source to promote, the gas source must be stable, small fluctuations, no water. Because gas and water are two different media, gas invisible, water visible, solenoid valve is a precision components, water in the electromagnetic, trachea, cylinder retention will produce scale, resulting in reversing solenoid valve jam, channeling gas, gas seal wear, blow-by and leak of air in the cylinder, when the cylinder moves, there is no force, crawl, no action or sudden quick action, burst of Trachea, joint and so on.
