As further optimization to technique scheme; Said secondary ejecting mechanism comprises and is installed between said mould seat board and the said dynamic model and is driven by oil cylinder ejector retainner plate and the thimble web that moves up and down; Be fixed with push rod on the said ejector retainner plate; Be fixed with the mesh pull bar on said ejector retainner plate and the said thimble web, be shaped on pit on the said dynamic model, the mesh ejector retainner plate is installed in the said pit; Be fixed with the mesh thimble that the mesh to automobile door plate ejects on the said mesh ejector retainner plate, promising mesh ejector retainner plate also be set in the said pit eject the mesh of power ejector spring is provided; The upper end of said mesh pull bar is fixed on the said mesh ejector retainner plate, and the lower end of said mesh pull bar is shaped on the pole cap of convex hoop shape, is shaped on the pilot hole that cooperates with said pole cap size on the said thimble web, and said pole cap is positioned at said pilot hole and can slides up and down.
As the further optimization to technique scheme, said mesh ejector retainner plate upper surface is equipped with and prevents that the mesh that said mesh ejector retainner plate and said dynamic model bump from ejecting limited block.
As the further optimization to technique scheme, said ejector retainner plate upper surface is equipped with the mould limited block that prevents that said ejector retainner plate and said dynamic model from bumping.
As the further optimization to technique scheme, the upper surface of said mould seat board is equipped with the mould pad.
As the further optimization to technique scheme, the pit mouth on the said dynamic model is provided with installing plate, and said installing plate is through being bolted on the said dynamic model, and the head of said bolt runs through said mesh ejector spring and said mesh ejector retainner plate respectively.
As further optimization, the mesh limited block that prevents that said mesh ejector retainner plate and said installing plate from bumping is installed on the said installing plate to technique scheme.
When the present invention ejects at the automobile door plate to the band mesh; The mesh part independently ejects; Be equivalent to that promptly whole automobile door plate is carried out twice time and eject, reduced the thimble length at mesh place and ejected distance, reduced the mesh thimble significantly the probability of disconnected (bending) takes place.Thereby prolong die life and cycle, improve the stability of mould, guarantee the production cycle of product.
Below in conjunction with accompanying drawing embodiment of the present invention is further specified.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiments of the present invention;
Fig. 2 is the enlarged diagram of the ejecting structure in the mesh zone among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, a kind of secondary ejecting mechanism of automobile door plate injection mold comprises mould seat board 7, and said mould seat board 7 is installed dynamic model 1 through mould pin 18, is provided with secondary ejecting mechanism between said mould seat board 7 and the said dynamic model 1.
Secondary ejecting mechanism wherein comprises the ejector retainner plate 5 and thimble web 6 that is installed between said mould seat board 7 and the said dynamic model 1, and said ejector retainner plate 5 is driven by oil cylinder 17 with thimble web 6 and moves up and down, and above-mentioned oil cylinder 17 is installed in the sidewall of dynamic model 1.
Be fixed with push rod 13 on the said ejector retainner plate 5, push rod 13 is used to eject the part of automobile door plate except that mesh.Be fixed with mesh pull bar 9 on said ejector retainner plate 5 and the said thimble web 6; Be shaped on pit on the said dynamic model 1; Mesh ejector retainner plate 4 is installed in the said pit; Be fixed with the mesh thimble 2 that the mesh 16 to automobile door plate 15 ejects on the said mesh ejector retainner plate 4, promising mesh ejector retainner plate 4 also be set in the said pit eject the mesh of power ejector spring 10 is provided.
The upper end of said mesh pull bar 9 is fixed on the said mesh ejector retainner plate 4; The lower end of said mesh pull bar 9 is shaped on the pole cap 91 that is convex hoop shape; Be shaped on the pilot hole 61 that cooperates with said pole cap 91 sizes on the said thimble web 6, said pole cap 91 is positioned at said pilot hole 61 and can slides up and down.According to actual needs, the correspondence position of mould seat board 7 also can be shaped on the pilot hole that cooperates with said pole cap 91 sizes, and is as the extension to the pilot hole on the thimble web 6 61, as shown in Figure 1.
As the further optimization to technique scheme, said mesh ejector retainner plate 4 upper surfaces are equipped with and prevent that said mesh ejector retainner plate 4 and the mesh that said dynamic model 1 bumps from ejecting limited block 3.
As the further optimization to technique scheme, said ejector retainner plate 5 upper surfaces are equipped with the mould limited block 11 that prevents that said ejector retainner plate 5 and said dynamic model 1 from bumping.
As the further optimization to technique scheme, the upper surface of said mould seat board 7 is equipped with mould pad 12.
As further optimization to technique scheme; Pit mouth on the said dynamic model 1 is provided with installing plate 19; Said installing plate 19 is fixed on the said dynamic model 1 through bolt 14, and the head of said bolt 14 runs through said mesh ejector spring 10 and said mesh ejector retainner plate 4 respectively.In this structure, bolt 14 had both played the effect of central spindle of the spring, kept the stability in spring 10 telescopic process; Play the effect of the guide pillar of mesh ejector retainner plate 4 again, keep mesh ejector retainner plate 4 stability in the process that moves up and down.
As further optimization, the mesh limited block 8 that prevents that said mesh ejector retainner plate 4 and said installing plate 19 from bumping is installed on the said installing plate 19 to technique scheme
Operation principle of the present invention is following:
When ejecting after the mould die sinking, ejector retainner plate 5 moves upward under the effect of oil cylinder 17 with thimble compound plate 6, and push rod 13 also heads on other zone slowly demoulding of automobile door plate except that mesh.In the said process, the pole cap 91 of mesh pull bar 9 lower ends breaks away from ejector retainner plate 5; Meanwhile; Mesh ejector retainner plate 4 is under the effect of mesh ejector spring 10; Meeting drives mesh thimble 2, mesh pull bar 9 moves upward together; Mesh limited block 3 on mesh ejector retainner plate 4 contacts with dynamic model 1, makes the mesh part demoulding smoothly of automobile door plate, mesh ejecting mechanism completion so far eject action (this is for ejecting the first time).Subsequently, ejector retainner plate 5 continues to eject under oil cylinder 17 effects, contacts with dynamic model 1 bottom surface up to mould limited block 11, and the automobile door plate of band mesh is ejected (this is for ejecting for the second time) fully, ejects process thereby accomplished whole secondary.
When mould resets; Ejector retainner plate 5 resets downwards under the effect of oil cylinder 13 with thimble compound plate 6; When ejector retainner plate 5 with after the pole cap 91 of mesh pull bar 9 lower ends contacts; Can drive mesh pull bar 9, mesh ejector retainner plate 4, mesh thimble 2 and move downward together, contact with mould pad 12, the mould completion that resets up to mould thimble compound plate 6.
In the present embodiment, the distance that ejects of mesh thimble 2 is 10mm, and prior art will eject 145mm, because the distance that ejects of push rod 13 is 145mm in the present embodiment, and in the prior art, the mesh thimble equates with the distance that ejects of push rod.This shows, mesh thimble 2 length of this ejecting mechanism with eject distance and all significantly reduce, the probability of disconnected (bending) takes place thereby reduced mesh thimble 2 significantly.
More than describe preferred embodiment of the present invention in detail.The ordinary skill that should be appreciated that this area need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technical staff in the art on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall in protection scope of the present invention under this invention's idea.
