Vertical injection molding machine often see problems to solve the problem

A, why the same kind of plastic, the same kind of injection molding process specification, in the same kind of vertical injection molding machine model specification is the same, but the injection sometimes stable, sometimes unstable, is the problem of mechanical equipment? This problem is a conundrum encountered by many great masters. There are several aspects summarized below:

1, pay attention to the machine equipment on the computer to observe the pressure trend chart, to see if the pressure is stable?

2, the basic parameters of the production process control parameters in a critical state (melting is not good)

3, occupancy, output difference,

4. Check the extruder screw and the overshot rubber ring, and whether there is anything unclean in the nozzle

5. Check the actual electric heater. Temperature difference

6, machine equipment and machine central parts damage is not the same

7, operator and operator between the actual operation rate difference

8, oil pump pressure, skeleton seal inspection

Two, the noise is very large when the vertical injection molding machine shoots the glue. It can be better for a period of time after cleaning the screw of the extruder and oiling it, but it will appear again

1. Listen more carefully to what that noise is. Is the oil in there too dirty?

2. It may be caused by the difference between the screw of the extruder of the injection molding machine and the pivot of the cylinder. There is no deformation of the injection hydraulic cylinder!

3, the cylinder seat around the front and back shaking

Three, mechanical equipment injection pressure is insufficient

1. Whether the oil and gas separator network is blocked, and the pump is blocked

2. The frame seal of the injection cylinder has been damaged

3, check the system pressure, small pump pressure

4, occupancy pressure, occupancy flow output check

Four, vertical injection molding machine mechanical equipment glue overflow more than ten days or so problems continue to ask how to deal with?

1, if every mold is like this, that is the shooting stage is not calibrated.

2. It is the regional glue overflow on the joint surface of nozzle and mold.

3, the commodity economy production and processing emergency can be used a small piece of paper (general paper box paper) pad in the nozzle and the mold feeding mouth is in the middle.

4, the mold into the glue mouth sleeve to see if there is grinding. It is better to make the arc production of the nozzle to facilitate the matching with the mold.

5. Most of the injector nozzle and die nozzle are not aligned or the mold is not aligned or the precise positioning ring is not used to cause glue overflow because the injector platform is too moving.

6. Check whether the nozzle of the vertical injection molding machine matches the R Angle of the inclined surface of the mold. Check the nozzle port.

7, injection or dry fixation, feeding conversion seat back to the injector cylinder framework seal check.
