1. Check whether the screws of the core pull, cylinder, pressure plate, joint and other parts of the mold are loose or missing.
2. Check whether each core wire is pulled out, the travel switch, the micro switch, the position gauge, the emergency stop button, etc. are operating normally.
3. Check whether the oil level of the vertical horizontal injection molding machine is above the center line, whether the oil quality is good, and whether the oil temperature is normal (30~45 is best, and it can be used between 5~55).
4. Check for leaks or blockages in the oil cylinders, oil pipes, working seal connections, etc. of each water circuit and oil circuit.
5. Check whether there is enough lubricating oil in each lubrication point, oil pipe and centralized lubrication tank, whether it can be lubricated normally, and whether there are breaks and blockages in various parts.
6. Check whether there is any peculiar smell or abnormal sound in the switchboard, whether the components and wires are overheated, whether they are burnt, whether they fall off, whether there are dust or foreign objects, etc.
7. Check whether the ventilation and filtering devices in the switchboard of the vertical and horizontal injection molding machine work normally and whether the heat dissipation is good.
8. Check whether there are any abnormal sounds, overheating, etc. (main motor, demolding motor, oil motor, oil pump, oil
Cylinder and various mechanical transmission parts, etc.). Ensure good lubrication and heat dissipation.
9. Whether the action of each part (switch type, core pulling, head advance and retreat, base advance and retreat, injection, preform, rubber demoulding, die adjustment, etc.) is reasonable in pressure, speed, position, time, etc., whether the action is slow, whether Severe collision, whether the action is reliable
10. Check whether the safety protection devices of the vertical and horizontal injection molding machine are actually working and whether they are in normal use. (Each time you change the model, you need to adjust the mechanical bumper)
11. Check whether the thermocouple and heating ring are working properly.
12. Check whether the platforms of the vertical and horizontal injection molding machine are displaced.
