The slider injection molding machine is usually composed of injection system, mold closing system, hydraulic transmission system, electric control system, lubrication system, heating and cooling system, safety monitoring system and so on. Injection system injection system: injection system is one of the most important parts of the sliding plate injection molding machine. There are 3 main forms of injection type, such as plunger type, screw type and screw preplastic plunger. At present, the most widely used is the screw type. The effect is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized in a specified time. At a certain pressure and speed, the molten plastic is injected into the mold cavity through the screw.

Matters needing attention in hydraulic system operation of slide plate injection molding machine:
First, before starting the machine, the adjustment of the handwheel and handle on the system should be checked to be moved by the unrelated personnel, the position of the electrical switch, the stroke switch is normal, the installation of the tools on the host is correct and firm and so on, and then the exposed part of the guide and the piston rod is wiped and then the car can be driven.

Two, for the slide plate injection molding machine, the exhaust system should be exhausted. The system without exhaust device should be reciprocating and running, so that it can discharge natural gas naturally.
Three. The oil tank of the skateboard injection machine should be sealed with the seal oil tank. The air filter should be set up to prevent the invasion of the dirt and water at the aerated hole above. It should be filtered to clean the oil and keep the oil clean.

Four, check the oil surface to ensure that the skateboard injection molding machine system has enough fuel volume.
Five, the flow control valve of the sliding plate injection molding machine should be adjusted from a small flow to a large flow rate and should be adjusted gradually. The flow control valve of the synchronous motion actuator should be adjusted to ensure the smoothness of the movement simultaneously.

Six. The hydraulic oil of the skateboard injection machine should be regularly checked and replaced for the new use of the hydraulic equipment for 3 months or so, that is, the oil tank should be cleaned and replaced every half a year to 1 years.
Seven, the adjustment of the pressure control element should first adjust the pressure control valve of the system - the overflow valve will gradually increase the pressure from the pressure to zero when the pressure is zero, so that it can reach the prescribed pressure value and then adjust the pressure control valve in each loop. The pressure of the safety relief valve of the main oil pump is generally greater than the working pressure required by the actuating component. Force 10%--25%, the pressure valve of the fast motion hydraulic pump, its adjustment pressure is generally greater than the required pressure 10%--20%. If the pressure supplied by the unloading pressure supply control oil and lubricating oil road is kept in the 0.3--0.6MPa range, the adjustment pressure of the pressure relay of the slider injection molding machine should be lower than the oil supply pressure of 0.3--0.5MPa.
