Description

Bi-directional barb exiting sliding block mechanism
[technical field]
The present invention relates to a kind of slide block mechanism of mould, particularly a kind of bi-directional barb exiting sliding block mechanism.
[background technology]
Inside and outside a kind of plastic cement products homonymy, all there is the barb in the die sinking direction to exist, in general outside barb can select the feature die outer slide to withdraw from barb, and inboard barb only has with taper pin and realizes withdrawing from moulding, when interiors of products has rib structure again, then be difficult to design taper pin and withdraw from the inboard barb of moulding, need to adopt the male model inner slide to withdraw from the inboard barb of moulding, and common slide block mechanism can not be reached.
See also Fig. 1 and Fig. 2, its bi-directional barb exiting sliding block mechanism that illustrates respectively prior art is in the bi-directional barb exiting sliding block mechanism of the structural representation of matched moulds state and prior art in the structural representation of die opening state.The prior art bi-directional barb exiting sliding block mechanism is applied in the mould, with moulding one product 10, the side same position of this product 10 has outside barb 11 and inboard barb 12, the inner top surface of this product 10 also has rib structure 13, and this bi-directional barb exiting sliding block mechanism comprises that mainly a slide block body 20, an outer slide enter son 21, one inner slide 30, a shifting block 40.
This slide block body 20 can be arranged on the caster 60 slidingly, and an oblique guide hole 22 is set on it; This outer slide enters the front end that son 21 is fixedly arranged on this slide block body 20, and its front end extends into the outside barb 11 of this product 10 of moulding in the mother module core 61; This inner slide 30 can be arranged on the male model plate 70 slidingly, and its front end extends into male die core 71 and the inboard barb 12 of this product 10 of bending forming that makes progress, and the rear end of this inner slide 30 is provided with an oppositely oblique guide hole 31; This shifting block upper end is fixedly arranged on the upper mounted plate 50, and its lower end has one and stirs greatly structure 41 and a reverse little structure 42 of stirring, and is actively located in respectively in this oblique guide hole 22 and the oppositely oblique guide hole 31.
During for the first time die sinking, this upper mounted plate 50 separates first with this caster 60, this shifting block 40 is upwards extracted out, and this of its front end stirred greatly structure 41 and promoted this slide block body 20 to the direction slip away from mold center, enters the outside barb that son 21 withdraws from this product 10 thereby drive this outer slide; The oppositely little structure 42 of stirring of its front end promotes this inner slide 30 to the direction slip near mold center, thereby withdraws from the inboard barb 12 of this product 10.During for the second time die sinking, male model plate 70 separates with caster 60, and this product 10 can be ejected by ejecting mechanism.
The bi-directional barb exiting sliding block mechanism of prior art moves up and down by this shifting block 40, two structures 41 of stirring greatly with rightabout inclined-plane of shifting block front end act on respectively slide block body 20 and inner slide 30 with the reverse little structure 42 of stirring, drive that this outer slide enters son 21 and inner slide 30 slides in the opposite direction, thereby withdraw from outside barb 11 and the inboard barb 12 of these product 10 1 sides.But, the bi-directional barb exiting sliding block mechanism of prior art is because this shifting block 40 is stressed larger when the folding mould, reverse little block-dialing structure 42 insufficient strength of its front end, as easy as rolling off a log fracture, often need form removal inspection and replacing, so the bi-directional barb exiting sliding block mechanism job insecurity of prior art, security is less, and there are many limitation in practical application.
In view of this, be necessary in fact to develop a kind of working stability, safe and reliable bi-directional barb exiting sliding block mechanism.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of working stability, safe and reliable bi-directional barb exiting sliding block mechanism, the two-way inside and outside barb that withdraws from shaped article homonymy during die sinking.
For achieving the above object, the invention provides a kind of bi-directional barb exiting sliding block mechanism, be applied in the mould, this mould comprises upper mounted plate, caster and male model plate, it is characterized in that, this bi-directional barb exiting sliding block mechanism comprises:
One outer slide, its slip are arranged on this caster, and its front end extends into the outside barb of mold cavity forming product, and its rear end is provided with an oblique T-shaped groove;
A branch of, its upper end is fixedly arranged on this upper mounted plate, and this caster is passed in its lower end, and sets firmly one T-shaped oblique T-shaped groove with this outer slide in its side and be slidingly matched, and this T-shaped drives the outside barb that product is withdrawed from the outside slip of this outer slide during die sinking;
One inner slide, its slip is arranged on this male model plate, its front end extends into die cavity and the inboard barb of the bending forming product that makes progress, its rear end set firmly one with the reciprocal Angle Pin of this oblique T-shaped groove, this Angle Pin is actively located in the oblique guide hole of this caster, and this oblique guide hole drives inside slip of this inner slide by this Angle Pin and withdraws from the inboard barb of product during die sinking.
Preferably, these outer slide both sides arrange respectively a briquetting, and this briquetting is positioned this outer slide on this caster slidingly.
Preferably, also be installed with a wear-resistant block between this outer slide and this inner slide.This wear-resistant block can be avoided this outer slide and this inner slide directly contacts friction, reduces slider wear.
Preferably, this male model plate also is installed with a block on this inner slide exit axis, arranges between this block and this inner slide to be connected an elastic construction.More preferably, this elastic construction is a Compress Spring.This Compress Spring strain when die sinking is recovered, and auxiliary this inner slide inwardly slides and withdraws from the inboard barb of product.
During for the first time die sinking, this upper mounted plate separates first with this caster, and this bundle piece and this T-shaped move along the die sinking direction with this upper mounted plate, guide the outside slip of this outer slide to withdraw from the outside barb of product.
During for the second time die sinking, this caster separates with this male model plate, and the oblique guide hole on this caster guides this Angle Pin and this inner slide to slide to mold center's direction, and the front end of this inner slide withdraws from the inboard barb of product.
Compared to prior art, outer slide is by bundle piece and T-shaped outwards slip during bi-directional barb exiting sliding block mechanism die sinking of the present invention, inner slide moves inward by Angle Pin, withdraws from respectively outside barb and the inboard barb of product by successively twice die sinking, avoid in the prior art outer slide by single shifting block simultaneously during two-way withdrawing from stressed larger shifting block hold flimsy defective, simple in structure, process and assemble is convenient, and intensity is high, not easy to wear, working stability, safe and reliable.
