Secondary ejection

Large thin wall parts often need to point out a few level. Especially when the plastic parts not no damage to inherit the thimble should use a few more when the force applied level (usually use secondary ejection). Such as case diagram

Products are buckle the circular arc form, forced out will damage the torque. Design the mould structure of secondary ejection. Plunger plate adopts two groups (A and B group), needle in group A thimble. Out for the first time, push in group A thimble board, and by the magnet drives the plunger plate with group B, inclined top and thimble K make the products out lower die, for the second ejection arc lateral elastic deformation make room. Needle continued, this time round, the group B thimble board halted, and group A continue forward, inclined bumps out products, thimble K cannot ejection, buckle the product by the elastic deformation of emergence.

In this agency can use nylon plug or hook instead of a magnet to drive the group B thimble plate.
