CORE SETUP PAGE INJECTION MOLDING

 





 To switch on the core pull control option select the main “Core pulling control”  

 
 Depending on the optional available in the machine (see page 01 MACHINE DETAILS), Core 1 or core 2 or all cores can be selected  by selecting “Enable core 1” and “Enable core 2”  

 

 Core 1 may also be operated in rotating core mode by enabling the option ‘Rotating Core’ from the drop down menu 

 

 Cores movement with safety gate open is available as a selectable option. 
 
 For any core operations the corresponding “Enable core.” selection should be enabled. 
 
 If only two cores are to be selected, select core 1 and 2.   

 

 If any invalid core sequence is selected the message ‘Wrong Core Sequence’ appears. Please check and correct the core sequence. 
 
 Any combination of cores can be operated in parallel either during in or out, by enabling the respective selection switch. Please ensure that the cores are enabled before selecting the parallel operation. 
 
 Two cores operating in parallel must have the same in or out position selected. For instance if core 1 and 2 are to operate in parallel at mould open stop during in, select 1 and 2 in the ‘CORE IN’ selection column. 




CORE DIRECT: 

 

 Any particular core movement can be accomplished through the selection box “Core direct” for the corresponding core. Only one core should be selected at a time.  
 
 When core direct function is selected in manual or setting mode all the other movements of the machine are disabled (to protect the mould). This can be used for setting up the mould with cores. 
 
 Cores are integrated in the mould open and close sequence even for manual and setting mode.  The cores will operate according to the sequence selected. 


CORES IN AND CORE OUT: 

 

 The order in which the cores move is freely programmable with individual speed and pressure settings for all the cores.  
 
 Each core can be individually time dependent or limit switch dependent and the feature “switch off at end position” is also independent for each cores. 


Note:  If both the cores are selected at the same sequence (example core 1 in is 1 and core 2 in is also 1) then the speeds and pressures of the first core will be taken as long as it is active to move both the cores simultaneously. The mould movement will start only after both the cores have moved in (in this case).Similar logic applies to cores move out. 

 

 

In case cores movement is time dependent the cores will move (in / out) for the set time or until the core moved (in/ out) limit switch is pressed whichever occurs first. When core movement is time dependent, the selection “Switch off at end position” is invalid as the cores may not have yet reached the end position. In a case when mould sensing has occurred and core is already in the mould will not go back until the core is moved out by core direct 

 

 

 

Attention: Selection of core direct, bypasses the sequence of mould operation with core in/out condition. Hence the operator / tool setter must consult his superiors before selecting / operating core in “DIRECT MODE”. Since the possibility of mould damage exists in “CORE DIRECT MODE” operation.

TROUBLESHOOTING FLASH IN INJECTION MOLDING MACHINE

FLASH IN INJECTION MOLDING PRODUCT Flash is Nothing but just an extra material over the molded product , Flash causes loss of material at the time of molding and sometimes it also destroys the surface beauty of the product . MAJOR CAUSES OF FLASH 1. Material Too Hot at the time of injection and in the mold. 2. Injection pressure is too high. 3. Excessive Feeding of the material in the mold. 4. Improper or Uneven feeding of the material. 5. Poor parting line or the mating surfaces of the mold. 6. Mold deficiency means problem in the mold manufacturing. 7. Injection Pressure is higher than Clamping pressure. 8. Erratic or uneven or improper cycle time. TROUBLE SHOOTING THE FLASH TEMPERATURE :   Check the cylinder temperature that means check the temperature of your barrel make it low if it is higher. Reduce the temperature  of the nozzle that is an important aspect. Reduce the mold temperature if it is higher. MOLDING SETTINGS : Increase the clamping force to make proper cl...

INTRUSION IN INJECTION MOLDING

Image
Intrusion   If the intrusion time is set greater than zero, then the screw will be rotated during this time immediately prior to injection. Material will thus be introduced into the mould.     Both pressure and screw rotation speed can be set separately.  Cold Slug Removal  If it is necessary to remove the cold slug from the nozzle before injection, the appropriate selection can be made from the program options together with a time when the slug is to be removed by injection.   Both injection pressure and speed can be set separately.     This operation occurs before injection unit moves forward.

EJECTOR SETUP PAGE INJECTION MOLDING

Image
 Press Ejector hot key  Or Enter page number   Or Select page in page index menu  * Hydraulic ejector forward is controlled with single stage pressure and two speeds.  * Retract controls are with single pressure and single speed Ejector Forward (as per the above settings)   Hydraulic ejector is triggered when machine is at mould open-stop position.   At this position, the delay timer of 0.00 sec triggers the ejector at 160 bar pressure and a forward speed of 50%.    On reaching the trigger point 50 mm, the speed is changed to 50%.   Ejector forward movement is stopped at 160 mm.  At the forward end if multi stroking is not selected the stay forward time is actuated for the set time of 0 seconds  Ejector Retract (as per the above settings)      The ejector retracts at 25 bar pressure with 15% speed.   The same sequence is repeated once again as the ...
