Skateboard injection molding machine operation and the end of the matters needing attention

Matters needing attention in the operation of hydraulic system of sliding board injection molding machine:

A slide injection molding machine flow control valve should be adjusted from a small flow to a large flow and should be gradually adjusted, synchronous movement of components of the flow control valve should be adjusted together to ensure the stability of movement.

Two, slide injection molding machine hydraulic oil to punctual inspection, replacement of the new use of hydraulic equipment for 3 months should clean the tank to replace the new oil, every six months to one year for cleaning and oil change.

Three, the sliding board injection molding machine should check the system before starting the adjustment of the handwheel, handle is not moved by irrelevant personnel, electrical switch, travel switch azimuthal is not normal, the host is not accurate and robust installation of things, and then on the guide rail and piston rod exposure some to wipe before driving.

Four, check the oil level to ensure that the slide injection molding machine system has met the amount of oil.

About first five, adjusting to the pressure control components, adjust the system pressure control valve, relief valve from pressure to zero open tuning progress step by step, make it reach the pressure value, again in order to adjust the pressure of each circuit control valve, the main oil pump for safety relief valve to adjust pressure than general components required to work 10% - 25%, rapid movement of the hydraulic pump pressure valve, the adjustment pressure generally greater than the required 10% - 20%, if use unloading pressure supply control oil and lubricating oil way of common pressure should be within the scope of the 0.3-0.6 MPa, The adjustment pressure of the pressure relay of the slide injection molding machine should be generally lower than the oil supply pressure of 0.3-0.5Mpa.

Six, the slide injection molding machine has an exhaust device system should be exhaust, no exhaust device system should be reciprocating work many times to make it natural exhaust gas.

Seven, the slide injection molding machine tank should be covered with a sealed tank, the air filter should be set at the top of the air hole to prevent the invasion of dirt, water, etc., when refueling should be filtered to clean the oil, adhere to clean.

Slide injection molding machine is generally composed of injection system, mold closing system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system and so on. The effect of injection system injection system: the injection system is one of the most important components of the slide injection molding machine. Generally there are plunger type, screw type, screw pre-plastic plunger injection type 3 main ways. The screw type was the most widely used at that time. The effect is that a certain amount of plastic can be heated and plasticized in a regular period of time in one cycle of the injection machine, and then the molten plastic can be injected into the mold cavity through a screw at a certain pressure and speed. In a set of messy process, in the closed slide injection molding machine also want to pay attention to a few points. Note at the end of each processing of slide injection molding machine:

First, choose “ Throughout the manual &; Operation method, closing mold in a quiet state.

Two, do a good job of skateboard injection molding machine cleaning and maintenance.

Cut off the heating power supply, turn off the oil pump motor, the main power supply and the cooling water.

Four, close the hopper blanking insert board, choose “ Throughout the manual &; Operation method: remove the injection seat and repeat the pre-plastic feeding and injection, and exhaust the remaining material in the cylinder as much as possible.
