Description
Technical field
The present invention relates to a kind of mould applications.It is specifically a kind of to be used for the ejecting mechanism with column structure product.
Background technology
Some working of plastics are to be injected separately, and are then threaded together with self-tapping screw, twist the position of self-tapping screw, have one section
Column solid construction, self-tapping screw can be bitten into, this section of column structure is just BOSS posts, is exactly mainly to increase screw to bite
Partial thickness, prevent from being cracked by screw, screw will not be loosened.If not having this structure, the simply plastic construction of shell, spiral shell
Silk is had no way fixed.
KO holes are called top roller hole, are made on mould rear mold panel, are in order to which when allowing the injection machine to eject, top rod can be straight
Top is connect to ejector retainner plate, and empty avoiding is done in the hole dug on panel.
In the prior art in order to product is smoothly ejected, it will usually the scheme for ejecting BOSS post designs into sleeve, its
Structure is divided into two parts：Sleeve core bar and sleeve, in the outside of sleeve core bar, sleeve core bar is fixed under mould solid its sleeve bag
On fixed board, sleeve is fixed on upper ejector plate, and when forming machine, which hits bar, promotes liftout plate motion, upper ejector plate band moving sleeve is transported
It is dynamic, product is departed from sleeve core bar, ejecting product.But when product has sleeve above bottom plate KO holes, need preferential KO
Hole is designed, as shown in figure 1, making product ejection Design difficult, ejection is uneven, is not easy ejecting product, mould does not have production.
In order to solve the above-mentioned technical problem, Chinese patent CN204546968U discloses one kind and borrows ejecting structure, and it is wrapped
Include push rod, its one end staggers axial location where KO holes and is fixed in liftout plate；Panelling, it is fixed in male template, push rod
The other end pass through panelling；First push pedal, on panelling, one end of push rod abuts the first push pedal for it；Second push pedal, it is located at
In first push pedal, and it is connected with the first push pedal；Ejector sleeve, it includes bobbin and fuse, and fuse one end is fixed in panelling, the other end
The outer rim of shaped article projection, bobbin one end are fixed in the second push pedal, and the other end is stretched into product projection.By borrowing ejection
Structure, can solve product projection well and produce interference on the same axis with KO hole sites, the projection of product can not be stripped
The problem of.But the prior art is complicated, although and KO hole sites and product projection on the same axis, push rod and KO
But not on the same axis, product ejection still suffers from active force imbalance, the problem of being not easy to eject for hole and product projection.
The content of the invention
Therefore, the technical problems to be solved by the invention are that product ejection still suffers from active force injustice in the prior art
Weighing apparatus, the problem of being not easy to eject, and then provide that a kind of product ejection force balance easily ejects is used for column structure
The ejecting mechanism of product.
In order to solve the above technical problems, a kind of of the present invention is used for the ejecting mechanism with column structure product, along product
Direction is ejected, is disposed with from bottom to top：
Bottom plate, it is provided with top roller hole；
Being fixedly supported on has the support block of certain altitude on the bottom plate；
The male template being supported on the support block, male die core is provided with the male template；
Liftout plate, it is movably disposed in the space that the bottom plate, male template and support block surround, described in top roller warp
Top roller hole can promote the fixed plate to move along ejection direction；Also include
Core bar and sleeve, any one its one end of both the core bar and the sleeve offsets with column structure, the other end is solid
Surely it is arranged in the male template；Another its one end of both the core bar and the sleeve is fixedly installed on the liftout plate
The upper, other end is slidably socketed with the core bar.
The core bar is fixedly installed in the male template, and the sleeve is fixedly installed on the liftout plate.
Axially extending sliding groove is offered on the sleeve, the axial length of the sliding groove goes out more than or equal to product
The stroke of mould, fixture is provided with the core bar, and the fixture passes the sliding groove and is fixed in the male template
Fixed block be fixedly connected.
The fixture is the first pin, the through hole extended radially through is formed on the core bar, the pin is through described
Through hole is connected with the fixed block.
The axial length of the sliding groove is less than the height of support block.
The liftout plate is divided into upper ejector plate and lower liftout plate, and the core bar or the sleeve are fixedly installed on the upper top
Between ejecting plate and the lower liftout plate.
Radially be equipped with the second pin in described sleeve pipe, second pin and be arranged on the upper ejector plate and it is described under
Fixed plate between liftout plate is fixedly connected.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art：It is of the present invention to be used for that to there is column
The ejecting mechanism of infrastructure product, direction is ejected along product, is disposed with from bottom to top：Bottom plate, it is provided with top roller
Hole；Being fixedly supported on has the support block of certain altitude on the bottom plate；The male template being supported on the support block, it is described
Male die core is provided with male template；Liftout plate, it is movably disposed at the space that the bottom plate, male template and support block surround
Interior, top roller can promote the fixed plate to move through the top roller hole along ejection direction；Also include core bar and sleeve, the core bar and
Any one its one end of both described sleeves with column structure is offseted, the other end is fixedly installed in the male template；The core bar
Be fixedly installed on both the sleeve another its one ends on the liftout plate, the other end is slidably socketed with the core bar, i.e.,
By the way that core bar and sleeve are separately positioned on liftout plate and the male template, not only top roller hole and column structure are arranged on
On same axis, the axis of core bar and sleeve also with the active force of top roller on the same axis, force balance, easily ejection production
Product.
