Description

Spring secondary ejection mechanism
Technical field
The present invention relates to mould manufacture field, more particularly to a kind of spring secondary ejection mechanism.
Background technology
When a product need to design secondary ejecting mechanism, existing technology is that two groups of ejector retainner plates are designed on mould, is used Resin shutter or iron shutter control the ejection order of two groups of ejector retainner plates, so as to realizing that Double-ejection acts.
But this secondary ejecting mechanism being made up of resin shutter or iron shutter, during product volume production very not It is stable, mold repair number is added, causes larger cost to waste, defect is larger.
1. resin shutter is easy to wear, when mould mould temperature gradually rises, frictional force can be reduced gradually, so that secondary top Go out failure mechanisms.After this failure mechanisms, machine under mould need to be re-replaced or be tightened resin shutter, accumulation repair a die number compared with It is more, cause human cost to rise, dieparts cost increase, product turnout rate reduces.
2. caused frictional force is larger between iron opening and closing device assembly, part easy fracture.During product volume production, need to do more batches it is standby Part, so as to cause die cost to rise, repair a die and often cause human cost to rise, product turnout rate declines.

Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
Fig. 1 to Fig. 3 is referred to, the embodiment of the present invention includes:
A kind of spring secondary ejection mechanism, including:Thimble 10, ejecting structures, secondary ejection structure 30, a spring knots Structure, support nail 50 and limited block 60.
Described one end of thimble 10 is connected with male template 70, and the other end is connected with an ejecting structure 20;
Secondary upper ejector retainner plate 31 and secondary lower ejector retainner plate 32 of the secondary ejection structure 30 including interconnection, described two Secondary upper ejector retainner plate 31 and secondary lower ejector retainner plate 32 can directly be fixed by connectors such as bolts.
Ejecting structure includes a middle porose angled slide block 21, is sleeved on the thimble 10, once pushes up The lower end for going out block 21 is arranged in the secondary upper ejector retainner plate 31.
The spring structure includes spring base 41 and spring 42, and the spring base 41 is arranged on an angled slide block 21 Lower surface, and in the secondary upper ejector retainner plate 31 and secondary lower ejector retainner plate 32, the spring 42 is arranged on the spring base In 41.
There is support nail 50 between ejecting structure and the secondary ejection structure, branch support 50 in the present embodiment In spring base 41.The effect of support nail 50 is to keep out the injection pressure suffered by the thimble 10 on an angled slide block, adjustment top The height of pin 10.Active force can once be ejected to calculate by the decrement for calculating spring 42.
The limited block 60 is fixed on the upper surface of the secondary upper ejector retainner plate 32 by connectors such as bolts.
During work, the secondary ejection structure drives an ejecting structure to move upwards simultaneously in advance by spring structure Set a distance, complete first time thimble actuating length S1(As shown in Figure 2), in the present embodiment first time thimble actuating length S1 be from The upper surface of angled slide block 21 to the lower surface of male module 70;Then, an ejecting structure stop motion, it is described secondary Ejecting structure continues up preset distance, and compression spring structure, completes second of thimble actuating length A(Such as Fig. 3 institutes Show), second of thimble actuating length A is from the upper surface of limited block 60 to the lower surface of male module 70 in the present embodiment.
The area of thimble block 21 of the present embodiment is much smaller than the area of the secondary upper ejector retainner plate 31, the present embodiment Spring secondary ejection mechanism is applied to the mould for having a small amount of Double-ejection.
Fig. 4 show another embodiment, a kind of spring secondary ejection mechanism, including:Multiple thimbles 11 ', 12 ', are once pushed up Go out structure, secondary ejection structure 30 ', spring structure 40 ', support nail 50 ' and limited block 60 '.With Fig. 1 to embodiment illustrated in fig. 3 The main distinction be that an ejecting structure includes a liftout plate 21 ', the area of a liftout plate 21 ' and institute State that the area of secondary upper ejector retainner plate 31 ' is suitable, the limited block 60 ' is arranged on the upper surface of a liftout plate 21 '.This reality The spring secondary ejection mechanism for applying example is applicable to the mould of large area Double-ejection.
During work, the secondary ejection structure drives an ejecting structure to move upwards simultaneously in advance by spring structure Set a distance, first time thimble actuating length is completed, first time thimble actuating length is the upper table from limited block 60 ' in the present embodiment Face to the lower surface of male module 70 ';Then, an ejecting structure stop motion, the secondary ejection structure continue up Move preset distance, and compression spring structure completes second of thimble actuating length, second of thimble action row in the present embodiment Journey is from the upper surface of secondary upper ejector retainner plate 31 ' to the lower surface of a liftout plate 21 '.
Spring secondary ejection mechanism of the present invention has two kinds of forms, and the mould and large area for needing Double-ejection on a small quantity need secondary top The mould gone out, simplifies mold design, and processing cost is low, and fitter assembly is easy, and subsequent production is stable, and the number that repairs a die is few.Mould Tool Zhong Jialiaoci mechanisms are not limited by any injection molding machine!
And using the secondary ejecting mechanism mold design of shutter form complicated, production cost is high, and production is unstable, needs standby Many spare parts, cause cost to waste.Spring secondary ejection mechanism of the present invention, spring uses mould time minimum 300,000 times, in mould It can choose whether to change spring when being maintained, saved human cost, die cost, maintenance cost, ensure that mould exists Stability during volume production, improve the quality and shipment efficiency of product!
After using spring secondary ejection mechanism of the present invention on mould, it can substitute completely by resin or iron shutter institute group Into mechanism, reduce human cost and Mold Making cost.This secondary ejecting mechanism stability is very high, so as to avoid maintenance Cost, safety is reached into production, the purpose efficiently produced.This mechanism is researched and developed successfully to the technological innovation ability of our companies of lifting Serve obviously effect.The accessory that this mechanism is formed is normalized, so as to reduce design time, standard metaplasia Production reduces the production cost of part.Double-ejection is used in mould, it is possible to reduce thimble quantity in product, particularly flat thimble Quantity, flat thimble easily produces flash, have impact on product quality.But the secondary ejecting mechanism formed using shutter, Design is more complicated, and maintenance cost is high, and this mechanism is rarely employed in general mould, can only pass through the later stage flat thimble of artificial removal's product Flash.Using the spring secondary ejection mechanism of our companies, its stability ensure that product quality.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills Art field, is included within the scope of the present invention.
