There are two existing solutions to this problem. One method is to suggest the customer to modify the first back-off 15' so that the oblique direction of the first back-off 15' is parallel to the oblique direction of the second back-off 12, as shown in fig. 3, the demolding can be performed by using an ejector-drop type oblique ejection mechanism, and the moving direction B ' of the oblique ejector is the oblique directions of the first back-off 15' and the second back-off 12, so that both the first back-off 15' and the second back-off 12 can be demolding smoothly.
