The top right side of a kind of secondary ejection structure of mold above-mentioned, the lower ejector retainner plate is equipped with two groups of guide posts, institute
The bottom right side for stating ejector retainner plate is equipped with two groups of guide grooves matched with guide post.
The utility model has the following beneficial effects: the structure design of the utility model is reasonable, after mold ejects for the first time, product is still
It cannot smoothly demould, this will use the mode of Double-ejection demould plastic.And this secondary demoulding, it is pushed up when first time
When out, the first thimble and the second thimble move together, and product completely disengages out not yet, and the second thimble allows bit space at this time,
It can deform, be detached from, the first thimble of thimble ejects again at this time, and the second thimble is not moved relative to the first thimble at this time, and plastic is complete
Total detachment type chamber, completely disengages it, is removed from the molds finished product, either uses single or multicomponent ejector
Structure, ejection movement is all once to complete.But due to the requirement when shape of finished product is special or volume production, if one
After secondary ejection, finished product is still remained in die cavity, or can not Automatic-falling when, it is necessary to be further added by primary ejection movement, this
The Double-ejection of scheme, can be simple and effective, easily operated, does not need to increase supplementary structure.
