Align the molding die after the air blowing die is installed, hit the molding die, push it back and stick it to the rear guide rail; At this time, you can see whether it is parallel to the rear guide rail. Just adjust the rear guide rail parallel to the forming die.

It should be noted that:

1. When installing the front guide rail, do not clamp the raw material too loose to avoid changing the parallelism between the raw material and the rear guide rail.

2. If the size of the blowing die and the forming die is different, we should be parallel to the rear guide rail to avoid the influence of the blowing die.
