Description
Technical field
It the utility model is related to injection mold, in particular to will be adhered when being stripped for injection mold on the push rod of type face
Product moves with the hand a kind of simple push rod of the injection mold split away off and accelerates liftout attachment.
Background technology
Explanation：Injection mold is used for straight pushing tow and moved in the push rod that product departs from core, and the upper end of some push rods is provided with and system
Type face corresponding to shape face on the inside of product, existing and referred to as type face push rod；
When injection mold is stripped, after product departs from core, due to the cladding power between product and the type face end of type face push rod
It is larger, cause product to be adhered and hang over the type face end of type face push rod and be difficult to Automatic-falling, prior art is typically employed in injection
Set the utensil for being referred to as two sections of backing-out punch to carry out secondary pushing tow to product in mould, enable product self falling；Or use
Manually the product being adhered at the type face end of type face push rod is moved with the hand by instrument and split away off；Two sections of backing-out punch are purchased into
This height, and occupancy mould inside space is big, causes the body of mould to increase, increases whole mould integrated cost；Manually move with the hand de-
Fall product, efficiency is low, and working strength is big, is not suitable with unattended automation injection production；Therefore, there is cost in prior art
Height, efficiency is low, working strength is big, is not suitable with the problem of automated production and deficiency.
The content of the invention
