Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment one
See Fig. 1, a kind of buckle injection mold ejecting structure, comprises upper bolster and die shoe, upper bolster is provided with front mould insert 10, and die shoe is provided with lower bolster 13, and lower bolster 13 is provided with rear mold insert 9, front mould insert 10 and rear mold insert 9 match and form the forming part of buckle
Also comprise ejector retainner plate and lower ejector retainner plate, lower ejector retainner plate is placed on die shoe, and upper ejector retainner plate is placed on lower ejector retainner plate, and upper ejector retainner plate is connected by shutter 7 with lower ejector retainner plate;
Lower ejector retainner plate is provided with the through hole that can pass for injection machine push rod, and injection machine push rod can contact with upper ejector retainner plate through through hole;
Lower ejector retainner plate is installed with the push rod 5 be fixedly connected with lower bolster 13, upper ejector retainner plate is installed with through lower bolster 13, can be formed with injection moulding after the thimble 11 that contacts of buckle;
Lower bolster 13 is provided with limited post 8, and upper ejector retainner plate is provided with the through hole that can pass for limited post 8, and limited post 8 can contact with lower ejector retainner plate through through hole;
Front mould insert 10 is connected with upper bolster by spring 4, as shown in Figure 3.
Lower ejector retainner plate comprises the first ejector retainner plate 1 and the second ejector retainner plate 2 be connected.
Upper ejector retainner plate comprises the 3rd ejector retainner plate 3 and the 4th ejector retainner plate 6 that are connected.
Rear mold insert 9 upper end size is larger than lower end size, and rear mold insert 9 side is provided with supplementary insert 12, and rear mold insert 9 and supplementary insert 12 are combined into assembled inlay blocks, and assembled inlay blocks upper end size is less than lower end size.
Rear mold insert 9 due to upper end also larger than lower end size, so having added a supplementary insert 12 thereafter, be convenient to die-filling.Wherein supplement insert 12 size A and must be greater than rear mold insert 9 size B, as shown in Figure 2, step down when being convenient to assembling.Because this product cavity jacking part also belongs to forced stripper mechanism, so add spring 4 bottom front mould insert 10, arrange stroke-limit is L (as shown in Figure 1) simultaneously.What also should be noted that during design is exactly that cavity jacking actuator travel L must be greater than the stripping stroke of plastic in cover half part.
Embodiment two
An extrusion method for above-mentioned buckle injection mold ejecting structure, comprises the steps:
1) after injection step completes, mould die sinking;
2) front mould insert 10 is moved to rear mold insert 9 direction together with product, after walking to predetermined stroke, and front mould insert 10 stop motion;
3) continue die sinking, die shoe continues to move downward, and product is forced to deviate from front mould insert 10 under the pulling force of counterdie, and the demoulding of front mould side completes;
4) the upper ejector retainner plate of push rod promotion of injection machine ejects forward together with thimble 11, and under the effect of shutter 7, upper ejector retainner plate drives lower ejector retainner plate simultaneously, push rod 5 moves together, and push rod 5 drives rear mold insert 9 to move;
5) when under, ejector retainner plate moves to limited post 8, limited post 8 contacts with lower ejector retainner plate and spacing, all stop motions of lower ejector retainner plate, push rod 5 and rear mold insert 9;
6) push rod of injection machine continues to promote upper ejector retainner plate, and upper ejector retainner plate is separated by shutter 7 with lower ejector retainner plate;
7) upper ejector retainner plate continues to eject, thimble 11 contact product, and product is finally forced under the promotion of thimble 11 from rear mold insert 9, thus completes whole stripping action.
Embodiment three
When mould die sinking, front mould insert 10, under the effect of spring 4, is moved to rear mold direction together with product, when walking to stroke L, front mould insert 10 stop motion, object is to make front mould insert 10 depart from front model cavity one segment distance, reserves enough deformation spaces be used for the demoulding to product; Continue die sinking, product is forced to deviate from front mould insert 10 under the pulling force of rear mold, and the demoulding of front mould side completes smoothly; When mould starts to eject, the push rod of injection machine promotes upper ejector retainner plate and ejects forward together with all thimbles 11, and under the effect of shutter 7, upper ejector retainner plate drives together with lower ejector retainner plate, push rod 5 and rear mold insert 9 etc. simultaneously and moves; When walking to stroke L1, limited post 8 is spacing, and all stop motions such as lower ejector retainner plate, push rod 5 and rear mold insert 9, object is the space in order to make plastic have distortion.Upper ejector retainner plate continues to eject, and product is finally forced under the promotion of thimble 11 from rear mold insert 9, thus completes whole stripping action.
After adopting above-mentioned scheme, structure is simple, and be easy to processing, assembling, workpiece can eject easily and reliably, and simplifies mould structure, reduces mould difficulty and cost, shortens mold developing cycle, improve economic benefit.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
