Description
[technical field]
The present invention relates to a kind of ejecting structures of mold, and in particular to a kind of sliding block forced demoulding mechanism.
[background technique]
Fig. 1 and Fig. 2 is please referred to, Fig. 1 depicts a kind of structural schematic diagram of product, and the section view that Fig. 2 depicts Fig. 1 product is shown
It is intended to.There is the first barb 110 and the second barb 120, at this stage in injection molding product, using oil pressure on the product 100
The mode that cylinder drives exits barb 110 and the second barb 120.However, the not only molding time in such a way that oil hydraulic cylinder exits
It is long, and barb 110 and the second barb 120 are easily damaged when exiting barb, to not can guarantee the production of product 100
Quality and the production requirement for being unable to satisfy client.
In view of this, exiting machine it is really necessary to develop a kind of sliding block forced demoulding mechanism to solve above-mentioned use oil hydraulic cylinder
The low problem of molding cycle long production yield in structure.
[summary of the invention]
Therefore, the purpose of the present invention is to provide a kind of sliding block forced demoulding mechanism, which can be solved
Certainly have on product barb can not forced stripper mechanism the problem of.
In order to achieve the above object, sliding block forced demoulding mechanism of the invention is applied to die for molding product, the production
On product have the first barb and the second barb, the mold include upper mounted plate, stripper plate, caster, mother module core, male die core,
Male template, upper ejector plate, lower liftout plate and bottom plate, the sliding block forced demoulding mechanism include:
Fixed block is fixed on the lower end of the mother module core；
First sliding block is movably set in below the fixed block, and one end of first sliding block is fixedly connected on an oil pressure
Cylinder, the other end protrude into the first barb and the second barb of the male die core cooperation shaped article, also have in the middle part of first sliding block
One groove；
Second sliding block is movably set in the top of first sliding block, and one end of second sliding block, which extends downwardly, to be had
One convex block, the other end protrude into the first barb of the mother module core cooperation shaped article；
Beam block, one end are fixed on the fixed block, the other end activity of the beam block be fixed on first sliding block and
Among second sliding block.
Optionally, first sliding block is additionally provided with an elastic element close to convex block one end of second sliding block.
Optionally, the elastic element is spring.
Optionally, the length of the first sliding block further groove is greater than the length of convex block in second sliding block.
Optionally, the moving distance of the convex block in a groove is 10 millimeters.
Compared to the prior art, sliding block forced demoulding mechanism of the invention, when die sinking, caster moves up first and public
Template separates, and then mother module core also moves up a distance, then drives mobile 10 millimeters of the first sliding block to connect by oil hydraulic cylinder again
It contacts convex block, finally drives the first sliding block and the second sliding block to move together by oil hydraulic cylinder again, until exiting the first of product completely
Barb and the second barb then are completed to be opened by thimble ejecting product.The sliding block forced demoulding mechanism passes through the first sliding block twice
Exiting makes product realize forced stripper mechanism, not only saves the activity duration, also improves production efficiency.
[Detailed description of the invention]
Fig. 1 depicts a kind of structural schematic diagram of product.
Fig. 2 depicts the schematic cross-sectional view of Fig. 1 product.
Fig. 3 is painted structural schematic diagram of the present invention slider forced demoulding mechanism in the state of molding.
Fig. 4 is painted partial structural diagram of the present invention slider forced demoulding mechanism in the state of molding.
[specific embodiment]
It is preferably real below in conjunction with of the invention one further to illustrate technological means and its effect adopted by the present invention
It applies example and its attached drawing is described in detail.
It please refers to shown in Fig. 3 and Fig. 4, Fig. 3 is painted structure of the present invention slider forced demoulding mechanism in the state of molding and shows
It is intended to, Fig. 4 is painted partial structural diagram of the present invention slider forced demoulding mechanism in the state of molding.
In this present embodiment, sliding block forced demoulding mechanism 200 of the invention is applied to die for molding product 100, should
There is the first barb 110 and the second barb 120, the mold includes upper mounted plate 210, stripper plate 220, master mold on product 100
Plate 230, mother module core 240, male die core 250, male template 260, upper ejector plate 270, lower liftout plate 280 and bottom plate 290, institute
Stating sliding block forced demoulding mechanism 200 includes:
Fixed block 241 is fixed on the lower end of the mother module core 240；
First sliding block 242 is movably set in 241 lower section of fixed block, and one end of first sliding block 242 is fixedly connected
In an oil hydraulic cylinder 243, the other end protrudes into the first barb 110 and the second barb that the male die core 250 cooperates shaped article 10
120, which also has a groove 2421；
Second sliding block 244, is movably set in the top of first sliding block 242, and one end of second sliding block 244 is downward
Extending has a convex block 2441, and the other end protrudes into the first barb 110 that the mother module core 240 cooperates shaped article 10；
Beam block 245, one end are fixed on the fixed block 241, and the other end activity of the beam block 245 is fixed on described
Among one sliding block 242 and the second sliding block 244.
In this present embodiment, first sliding block 242 is additionally provided with one close to 2441 one end of convex block of second sliding block 244
Elastic element 246, the elastic element 246 assist the return of the second sliding block 244.
In this present embodiment, the elastic element is spring.
In this present embodiment, the length of 242 further groove 2421 of the first sliding block is greater than convex block in second sliding block 244
2441 length, so that second sliding block 244 slides in the groove 2421 of first sliding block 242.
In this present embodiment, moving distance of the convex block 2441 in groove 2421 is 10 millimeters.
Referring again to Fig. 3, after the completion of product 100 is molded and formed, mold starts to be opened, upper mounted plate 210 and stripper plate
220 move up a distance, and then mother module core 240 begins to move up a distance until being detached from product 100, together with this
When, the fixed block 241 on mother module core 240 also moves up, and beam block 245 is driven to exit the first sliding block 242 and the second sliding block
244；Then, starting oil hydraulic cylinder 243 drive the first sliding block 242 exit product 100 the first barb 110 and the second barb 120 to
Side is mobile, touches the second sliding block 244 after 10 millimeters of movement, then oil hydraulic cylinder 243 drives the first sliding block 242 and second
Sliding block 244 moves together, until the second sliding block 244 exits the first barb 110 and the second barb 120 of product 100；Finally, again
It completes to be opened by thimble ejecting product 100.
Compared to the prior art, sliding block forced demoulding mechanism 200 of the invention first drives first to slide by oil hydraulic cylinder 243
Block 242 exits the first barb 110 and the second barb 120 of product 100, drives the second sliding block 244 then through oil hydraulic cylinder 243
The first barb 110 and the second barb 120 for exiting product 100, realize makes product 100 complete to force to take off by exiting twice
Mould.The sliding block forced demoulding mechanism 200 not only saves the stripping operation time, but also greatly improves production efficiency.
It is noted that the present invention is not limited to the above embodiments, any person skilled in the art is based on this hair
Bright technical solution both falls within protection model of the invention to any simple modification, equivalent change and modification made by above-described embodiment
In enclosing.
