Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment one
Referring to Fig. 1, a kind of buckle injection mold ejecting structure, including 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 constitute the forming part of buckle
Also including 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 and lower ejector retainner plate are connected by shutter 7;
Lower ejector retainner plate is provided with the through hole being available for injection machine push rod traverse, and injection machine push rod may pass through through hole and contacts with upper ejector retainner plate;
Lower ejector retainner plate is installed with the push rod 5 that be connected fixing 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 being available for limited post 8 traverse, and limited post 8 may pass through through hole and contacts with lower ejector retainner plate;
Front mould insert 10 is connected with upper bolster by spring 4, as shown in Figure 3.
Lower ejector retainner plate includes the first ejector retainner plate 1 and the second ejector retainner plate 2 being connected.
Upper ejector retainner plate includes the 3rd ejector retainner plate 3 and the 4th ejector retainner plate 6 being connected.
Rear mold insert 9 upper end size is bigger 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 is also bigger than lower end size due to upper end, so having added a supplementary insert 12 behind, it is simple to die-filling. Wherein supplement insert 12 size A and have to be larger than rear mold insert 9 size B, as shown in Figure 2, it is simple to step down during assembling. Owing to this product cavity jacking part falls within forced stripper mechanism, so adding spring 4 bottom front mould insert 10, arrange stroke-limit is L (as shown in Figure 1) simultaneously. During design it is also noted that be exactly that cavity jacking actuator travel L have to be larger than the plastic stripping stroke in cover half part.
Embodiment two
The extrusion method of a kind of 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) continuing die sinking, die shoe continues to move downward, and product forces to deviate from front mould insert 10 under the pulling force of counterdie, and the demoulding of front mould side completes;
4) push rod of injection machine promotes upper ejector retainner plate to eject forward together with thimble 11, and under the effect of shutter 7, upper ejector retainner plate drives lower ejector retainner plate, push rod 5 to move together simultaneously, 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 and spacing with lower ejector retainner plate, lower ejector retainner plate, push rod 5 and the wholly off motion of rear mold insert 9;
6) push rod of injection machine continues to press on 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 finally is forced under the promotion of thimble 11 from rear mold insert 9, thus completing 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, it is therefore an objective in order to make front mould insert 10 depart from front model cavity one segment distance, reserve enough deformation spaces for the demoulding to product; Continuing die sinking, product forces to deviate from front mould insert 10 under the pulling force of rear mold, and the demoulding of front mould side smoothly completes; When mould starts to eject, the push rod of injection machine promotes upper ejector retainner plate to eject forward together with all thimbles 11, under the effect of shutter 7, upper ejector retainner plate drive lower ejector retainner plate, push rod 5 and rear mold insert 9 etc. simultaneously together with move; When walking to stroke L1, limited post 8 is spacing, the wholly off motion such as lower ejector retainner plate, push rod 5 and rear mold insert 9, it is therefore an objective in order to make plastic have the space of deformation. Upper ejector retainner plate continues to eject, and product finally is forced under the promotion of thimble 11 from rear mold insert 9, thus completing whole stripping action.
After adopting above-mentioned scheme, simple in construction, it is easy to processing, assembling, workpiece can eject easily and reliably, and simplifies mould structure, reduces mould difficulty and cost, shortens mold developing cycle, improves economic benefit.
Above in conjunction with accompanying drawing, the present invention is exemplarily described; the obvious present invention implements and is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all within protection scope of the present invention.
