Description
Technical field
The utility model relates to needles in a kind of interference processing structure more particularly to a kind of ejector sleeve for mold and KO column
Interfere processing structure.
Background technique
It has determined that and can not change in the type machine of this mold, in the fixed situation in KO column position of mold, to save production
Cost, it is desirable that KO column can be retained in the case where big molding machine and mold is not added.
Chinese patent 201720986818.4 discloses a kind of KO rod structure as ejector pin, including from top to bottom successively
The upper ejector plate of setting, lower liftout plate, ejector sleeve needle plate, bottom plate, thermal insulation board and KO column, it is characterised in that: the KO column packet
The cylinder being arranged on KO seat board and KO seat board is included, is offered on the bottom plate and thermal insulation board under KO corresponding with KO seat board
Through-hole, offers through-hole on KO corresponding with cylinder on ejector sleeve needle plate, and through hole on KO is provided with bottom on ejector sleeve needle plate
Lower liftout plate is run through in the ejector sleeve pin hole being connected to KO lower through-hole, ejector sleeve pin hole upper end, and upper ejector plate corresponds to ejector sleeve pin hole and is provided with
Ejector sleeve hole is equipped with ejector sleeve in ejector sleeve hole, the ejector pin that top is pierced by ejector sleeve is equipped in ejector sleeve pin hole, ejector pin lower end passes through
Briquetting component or grub screw lock on ejector sleeve needle plate, and the maximum distance between ejector sleeve needle plate lower end surface and KO seat board is
L+a, L are the practical ejection distance of mold, and a is reserved ejection distance.Its structure is relatively complicated, and when in use, exists
Inconvenience.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact-sized, solves in ejector sleeve
Needle and KO column interfere processing structure in needle and the ejector sleeve for mold of KO column interference.
Above technical problems of the utility model are mainly solved by the following technical scheme:
Needle and KO column interfere processing structure, including product in a kind of ejector sleeve for mold, further include bottom plate and ejector sleeve, institute
The top for the bottom plate stated is equipped with B plate, needle fixed plate in ejector sleeve is equipped between the bottom plate and B plate, the top of the bottom plate is set
There is bottom plate needle, the top of the bottom plate needle is equipped with panel needle, and the bottom of the ejector sleeve covers pressing plate and panel needle by ejector sleeve
Fixed, it is in the movable limited post touched, needle fixed plate in the ejector sleeve that the top of the panel needle, which is equipped with B board bottom portion,
In be equipped with and drive the KO column that shifts up of bottom plate needle, needle in ejector sleeve is equipped in the ejector sleeve, the bottom of needle in the ejector sleeve
It is fixed in ejector sleeve in needle fixed plate, the KO column drives panel needle to shift up by bottom plate needle, the panel needle band
Dynamic ejector sleeve shifts up and ejector sleeve shifts up ejecting product.
Preferably, the displacement spacing of the KO column is 50mm, the displacement spacing of the limited post is 45mm.
Preferably, passing through spiral shell respectively between needle fixed plate and bottom plate, between ejector sleeve set pressing plate and bottom plate needle in the ejector sleeve
Bolt is fixed.
Needle and KO column Interference resolution principle in ejector sleeve: needle fixed plate is fixed on motionless on bottom plate in increase ejector sleeve, by ejector sleeve
Interior needle maintenance, which is set, is lifted to fixed above KO column, (needle is generally fixed on bottom plate in traditional dies ejector sleeve) KO in ejection
Column and arcuate part have the empty avoiding section of 50mm, so that KO column is had the operating range of 50mm, (ejection stroke of the mold has 45mm；It stays
The empty avoiding gap of 5mm prevents from interfering) meet the ejection stroke of mold 45mm.
Effect and advantage after improvement: do not have to replacement and increase injection molding machine, save production cost；Product ejection is not changed, and is had
It ejects and balances conducive to product；Reduce die manufacturing cost.
Therefore, needle and KO column interfere processing structure in the ejector sleeve for mold of the utility model, compact-sized, are promoted and are added
Work is high-efficient, improves product quality.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view when not ejecting of the utility model；
Schematic cross-sectional view when Fig. 2 is the ejection of the utility model；
Fig. 3 is the utility model schematic cross-sectional view.
