As the further optimization to technique scheme, the pit mouth on the described dynamic model is provided with installing plate, and described installing plate is bolted on the described dynamic model, and the head of described bolt runs through respectively described mesh ejector spring and described mesh ejector retainner plate.
The utility model is when ejecting the automobile door plate with mesh, the mesh part independently ejects, namely be equivalent to whole automobile door plate is carried out ejecting for twice, reduced the thimble length at mesh place and ejected distance, decrease the mesh thimble probability of disconnected (curved) occurs.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 utility model is described further.
Description of drawings
Fig. 1 is the structural representation of a kind of preferred embodiments of the utility model;
Fig. 2 is the enlarged diagram of the ejecting structure in the mesh zone among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, a kind of secondary ejecting mechanism of automobile door plate injection mold comprises mould seat board 7, and described mould seat board 7 is installed dynamic model 1 by mould pin 18, is provided with secondary ejecting mechanism between described mould seat board 7 and the described dynamic model 1.
Secondary ejecting mechanism wherein comprises ejector retainner plate 5 and the thimble web 6 that is installed between described mould seat board 7 and the described dynamic model 1, and described ejector retainner plate 5 and thimble web 6 are driven by oil cylinder 17 and move 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 described ejector retainner plate 5, push rod 13 is used for ejecting the part of automobile door plate except mesh.Be fixed with mesh pull bar 9 on described ejector retainner plate 5 and the described thimble web 6, be shaped with pit on the described dynamic model 1, mesh ejector retainner plate 4 is installed in the described pit, be fixed with the mesh thimble 2 that the mesh 16 to automobile door plate 15 ejects on the described mesh ejector retainner plate 4, promising mesh ejector retainner plate 4 also be set in the described pit eject the mesh of power ejector spring 10 is provided.
The upper end of described mesh pull bar 9 is fixed on the described mesh ejector retainner plate 4, the lower end of described mesh pull bar 9 is shaped with the pole cap 91 that is convex hoop shape, be shaped with the pilot hole 61 that cooperates with described pole cap 91 sizes on the described thimble web 6, described pole cap 91 is positioned at described 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 with the pilot hole that cooperates with described pole cap 91 sizes, as the extension to the pilot hole 61 on the thimble web 6, as shown in Figure 1.
As the further optimization to technique scheme, described mesh ejector retainner plate 4 upper surfaces are equipped with the mesh ejecting limit block 3 that prevents that described mesh ejector retainner plate 4 and described dynamic model 1 from bumping.
As the further optimization to technique scheme, described ejector retainner plate 5 upper surfaces are equipped with the mould limited block 11 that prevents that described ejector retainner plate 5 and described dynamic model 1 from bumping.
As the further optimization to technique scheme, the upper surface of described mould seat board 7 is equipped with mould pad 12.
As the further optimization to technique scheme, pit mouth on the described dynamic model 1 is provided with installing plate 19, described installing plate 19 is fixed on the described dynamic model 1 by bolt 14, and the head of described bolt 14 runs through respectively described mesh ejector spring 10 and described mesh ejector retainner plate 4.In this structure, bolt 14 had both played the effect of central spindle of the spring, the stability in keep-spring 10 telescopic process; Play again the effect of the guide pillar of mesh ejector retainner plate 4, keep move up and down stability in the process of mesh ejector retainner plate 4.
As the further optimization to technique scheme, the mesh limited block 8 that prevents that described mesh ejector retainner plate 4 and described installing plate 19 from bumping is installed on the described installing plate 19
Operation principle of the present utility model is as follows:
When ejecting after the mould die sinking, ejector retainner plate 5 and thimble compound plate 6 move upward under the effect of oil cylinder 17, and push rod 13 also heads on other zone slowly demoulding of automobile door plate except 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, until the mesh limited block 3 on the mesh ejector retainner plate 4 contacts with dynamic model 1, so that the smoothly demoulding of the mesh of automobile door plate part, so far the mesh ejecting mechanism is finished and is ejected action (this is for ejecting for the first time).Subsequently, ejector retainner plate 5 continues to eject under oil cylinder 17 effect, until mould limited block 11 contact with dynamic model 1 bottom surface, is ejected (this is to eject the second time) fully with the automobile door plate of mesh, thereby has finished whole Double-ejection process.
When mould resets, ejector retainner plate 5 and thimble compound plate 6 reset downwards under the effect of oil cylinder 13, when ejector retainner plate 5 with after the pole cap 91 of mesh pull bar 9 lower ends contacts, meeting drive mesh pull bar 9, mesh ejector retainner plate 4, mesh thimble 2 move downward together, until die ejector pin compound plate 6 contacts with mould pad 12, mould resets and finishes.
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 and eject distance and all significantly reduce, thereby decrease mesh thimble 2 probability of disconnected (curved) occurs.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technical staff, all should fall in the protection domain of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment according to design of the present utility model.
