Generally speaking, the ejection action of the finished product from the mold is completed at one time, whether using single or multi-component ejection mechanism. However, due to the special shape of the finished product, or the requirement of mass production, if the finished product is still in the mold cavity after one ejection, or when it can not automatically fall off, it needs to add another ejection action. Such ejection action design is called 2 Times ejection. 2 Times ejection can make ejection flow smoothly. For some products requiring larger ejection travel, the use of 2 Times ejection can reduce the force exerted by the ejection pin and avoid the defects caused by the ejection pin....
