The injection mold cavities are distributed in two or more layers, arranged in an overlapping manner, which is equivalent to stacking multiple pairs of injection molds together. Efficient stacked molds can increase production by multiple layers without increasing the locking force on one injection machine and one operator, greatly improving production efficiency and equipment utilization, saving production costs and human resources.

Key points of efficient stacked mold design

1) After the injection mold is opened, the main nozzle cannot detach from the guide sleeve, and attention should be paid to whether the length of the main nozzle and the setting of the mold opening stroke are reasonable;

2) Verification requirements for the large opening stroke and plasticization amount of injection molding machine Z;

3) The pre molding efficiency of the injection device should be high;

4) Increase the injection rate appropriately;

5) Pressure release of hot runner melt;

6) Handling the relationship between cavity layout and main nozzle.
