The actual meaning for all motions names of molding machine on real sites:

1. Pre-blowing: when the machine begins to closing mould, the fixed mould’s air blowing valve and movable mould’s air blowing valve begin to blow air(if the process is set as steam blowing air, they are fixed mould’s steam valve and movable mould’s steam valve). The blowing time is the set time by parameters.

2. Waiting after pre-blowing. After pre-blowing, the machine will wait for some time and then close mould.

3. The time delay before reverse: this parameter is used for counteracting electric motor’s inertial effect, that is the elevator fall time without electricity.

4. The material feeding gap: the seam production time that the motor stops in the material feeding limiting displacement and reverses.

5. The material feeding: this parameter is used for setting the machine’s material feeding time.

6. The material feeding interval: this time is useful in many times material feeding. For first material feeding process, the parameter has no effect. For second material feeding process, it needs pause for some time in the middle process. The time is material feeding interval.  

7. The second material feeding: when the material feeding isn’t enough, we can consider to choose second material feeding. The later material feeding time is second material feeding time.

8. The backward material: After material feeding finishes, we close the material feeding valve.The raw material will return to material warehouse. This time is backward material time.

9. The pre-heating 1: After the material feeding finishes, the fixed mould steam valve and movable mould steam valve open for pre-heating. This time is pre-heating time 1.

10. The mould locking:the movable mould comes down until the closing mould is finished from material feeding interval. This time is called “mould locking time”. Please notice that this parameter value is generally set around 0.5 s. It is screw molding machine. If the electric motor still operates, the electric motor’s electric current enlarges quickly after movable mould locking arrive in place. If the time is too long, it will damage the electric motor. Pay much attention to it in your operation process!

11. Pre-heating 2: After mould locking, the fixed mould steam valve and movable mould steam valve open for pre-heating. This function is completely same with pre-foaming 1. The difference: the former is carried out before mould locking and the latter is carried out after mould locking.

12. The penetration times: when we choose the penetration heating process as pressure way, this parameter plays a role. When the pressure in the mould rises, pressure gauge in the electric connecting point reaches upper limit, noted as one-time penetration. At this time, the steam valve will close and the pressure will decrease. It is repeated until it gets the set times. The flow enters into next step.

13. The fixed mould heating: the penetration and heating time is fixed mould heating time. It starts timing from the pressure gauge reaches lowest limit. Only when the parameter is as “time way” or “simultaneous meeting” in process choice, it has effect. For the “pressure way” , this parameter hasn’t effect.

14. The air discharge of movable mould: the parameter set is very flexible. For the general fixed mould’s penetration heating process, it is the electric motion of the fixed mould steam valve and fixed mould water discharge  valve. In such situation, the fixed mould pressure rises slowly.If the parameter sets the time value, the movable mould water discharge valve will close with electric motion after time overs. Thus, the fixed mould pressure will increase quickly. If the set time is 0, the movable mould ’s water discharge valve will close when the fixed mould begins to heat. If the time set is long（it exceeds fixed mould’s heating time），the movable mould ’s water discharge valve won’t close in the whole fixed mould heating process. This parameter is efficient no matter which kind of heating way the process chooses.

15. In the movable mould heating process, it penetrates the movable mould heating time. It begins to keep time from the pressure gauge reaches the lower limit level. Only this parameter is chosen as “time way” or “simultaneous meeting” in the process selection, it has the function. When it is chosen as “pressure way”, this parameter hasn’t the function.

16. The fixed mould air exhausting: the parameter set must be very flexible. For the general movable mould penetrating heating, the movable mould steam valve and movable mould water discharge valve get electric action. In this situation, the movable mould pressure increases slowly. If the parameter sets the time value, the fixed mould water discharge valve will close with electric action after the time overs. The movable mould pressure will increase quickly. If the time set is 0, the fixed mould water discharge valve will close when the movable mould begins to heat. If the time set is long(it exceeds the movable mould heating time), the fixed mould water discharging valve won’t close in the heating process. No matter what kind of heating way this parameter chooses in the process, it is efficient.

17. he heating intervals: in the process of pre-heating 2 switch to penetrating heating; fixed and movable mould heating in the penetrating heating; the penetrating heating switch to the main heating; the fixed mould steam valve, movable mould steam valve and fixed & movable mould water discharge valves will lose electricity. It is beneficial to the pressure release in the fixed and movable mould.

18. The main heating A/B: these two parameters are main heating time. In the main heating process, the fixed mould steam valve, movable mould steam valve, fixed mould water discharge valve and movable mould water discharge valve get electricity. If the pressure gets the upper limit, the corresponding steam valve will close. After two seconds, it will get electricity again.

19.  The temperature maintenance: the temperature maintenance time.

20.  The air exhaust: the pressure reduction time in the mould.

21. The fixed mould and movable mould water cooling: the cooling time is very important for demould. The water cooling sufficiency matters if ti can demould successfully. It is not better if the time is longer. If the water cooling time is too long, the products will stick on the mould and can’t fall off.

22.The fixed mould water discharge open/fixed mould water discharge close: these two parameters are used in the cold water processes. The reasonable set of these two parameters can make water cooling more sufficient. The implication is the fixed mould water discharge valve open and close time in the water cooling process. The fixed mould water discharge valve closes and the water level rises in the mould. The fixed mould water discharge valve opens and the cooling water in the mould is discharged out. For example, if the fixed mould water discharge open time is set for 5 seconds and fixed mould water discharge close time is set for 8 seconds, the fixed mould water discharge valve close for 8 seconds first and open for 5 seconds in the cooling process. The open and close processes continually repeat until the cooling overs. If the fixed mould water discharge valve doesn’t need to close in the water cooling process, it can set fixed mould water discharge valve time as “0”. The fixed mould water discharge open time can be set casually as a value(not 0). If it needs water cooling, we can close the fixed mould water discharge valve all the time. So we can set the fixed mould water discharge close time larger than water cooling time. The fixed mould water discharge open time can be set casually.

23. The movable mould water discharge open/movable mould water discharge close : these two parameters are used in cooling process. The reasonable set of these two parameters can make water cooling more sufficient. The implication is: the movable mould water discharge valve open and close time in the water cooling process. When the movable mould water discharge valve close, water level in the mould increases; When the movable mould water discharge valve open, the cooling water is discharged in the mould. For example, the movable mould water discharge valve open time is 5 seconds. The movable mould water discharge valve close time is 8 seconds. In the water cooling process, the movable mould water discharge valve close for 8 seconds and then open for 5 seconds. The open and close processes are repeated continually until the water cooling overs. If the movable mould water discharge valve doesn’t need to close in the water cooling process, we can set the movable mould water discharge close time as “0”. The movable mould water discharge open time can be set casually as a value(not 0). If it needs water cooling, we can close the movable mould water discharge valve all the time and set the movable mould water discharge close time larger than water cooling time. The movable mould water discharge open time can be set casually.

24. The pressure in the mould: the air blow time of air blow valve before opening the mould.

25. The preliminary mould: in the opening mould process, the movable mould lifts for some distance and then we blow air. This time is the preliminary mould time.

26. The fixed mould blowing air/ movable mould blowing air: the blowing air time in the demould process.

27. The second demould:When the process chooses the second demould, the movable mould should lift for some distance. Then it closes mould again. The lifting time is second demould time.

28. The second press mould: the second opening mould is the second closing mould time.

29. The opening mould overtime: if the demould time exceeds the set time, the system stops and gives an alarm. This value plays a role of protection. We should set it reasonably. In generally, the set time is a little longer than the open mould time so it can play a role of protection. If the set time is too long, it will lose the engine protection role.
