Description
Technical field
The utility model relates to injection moulded shell production field more particularly to a kind of Double-ejection knots based on injection mould
Structure.
Background technique
In traditional moulds design, some cover shape class large products, when designing ejection, rear mold is both needed to do pushing block or entire
The side side of pushing away, stress surface is uniform enough when to guarantee product ejection, and product is avoided ejection deformation occur, push up white, bursting, top
Split, sticking to mould phenomena such as.
As often product can add seam allowance, card slot, the position of bone or many places to draw in exterior sideview for the variation of Product Assembly type
Glue processing simplifies assembly process in order to preferably improve Product Assembly gap and positioning accuracy, whole to improve assembly effect
Rate.And the appearance of such product causes all seam allowances of product, card slot, the position of bone, draws and need to do secondary ejecting mechanism at glue position, in order to
Product seam allowance, card slot, the position of bone, draw glue position can smooth depanning, to guarantee product quality demand.
It is all relatively stringenter to product quality requirement in panel shell of television mold, especially to the entirety after product ejection
The demands such as degree of deformation, appearance surfaces are higher and higher.And with the variation of matching requirements, existing product appearance has one side to increase
Slot when conventional method designs, increases jacking block with two groups of ejector retainner plates or center lift-out structure designs, product seam allowance, card slot, bone
Position, draw glue position can smooth depanning, but this scheme is limited by very much, it is difficult to ensure that quality after product ejection and reducing mould
Has cost.
By taking card slot moulding as an example, such product increases jacking block with two groups of ejector retainner plates by tradition or center lift-out structure is set
Meter can be such that product card groove top goes out and depanning, but the whole ejection of product and mold will be greatly limited, the slot of product by
Structure influences possibly not arranging jacking block or thimble, then card slot can only with product by thimble together with eject, since card slot is small
Component, whole stress will lead to its damage, so that the overall quality after depanning is difficult to ensure.
Therefore, the existing technology needs to be improved and developed.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of secondary top based on injection mould
