Abstract

A twice ejecting mechanism which is applied to mould comprises a first ejector pin plate, a second ejector pin plate, a third ejector pin plate and a fourth ejector pin plate. These ejector pin plates are orderly flexibly arranged between a male template of the mould and a lower fixing plate. The first and the second ejector pin plates are fixedly connected. The first ejector pin plate is fixed with a first ejector pin. One end of the first ejector pin is moveably extended through the male template, a male mould core and a male mould entering part and is matched with the male mould entering part and a female mould core molding product. The male mould entering part is moveably arranged on the male mould core. The third and the fourth ejector pin plates are fixedly connected. The third ejector pin plate is fixed with a second ejector pin. One end of the second ejector pin is moveably extended through the first and the second ejector pin plates, the male template and a male mould core and is fixedly connected with the male mould entering part. Besides, a rotating block is pin jointed between the third and the fourth ejector pin plates. A pressing block is fixed on the male mould. One end of the pressing block is extended through the first and the second ejector pin plates and is resisted against the rotating block. The invention can smoothly eject products and avoid the products from being whitened and protruded.

Description

Secondary ejecting mechanism

Technical field

The present invention relates to a kind of secondary ejecting mechanism, particularly a kind of secondary ejecting mechanism that is applied in the mould.

Background technology

Plastic product is in shaping manufacture process, if product has overhead kick, ordinary circumstance need be run slide block or taper pin.Either way can't satisfy as if above, the structure that need revise product this moment just can the demoulding.Can influence the assembling function and the appearance of product like this.

Summary of the invention

In view of the above problems, the object of the present invention is to provide a kind of secondary ejecting mechanism, it ejects after can making formed product smoothly, and can avoid product pushed up white, the top protruding.

A kind of secondary ejecting mechanism provided by the invention, be applied in the mould, it comprises first, second, third and fourth ejector retainner plate, those ejector retainner plates are movably set between this mould male model plate and the bottom plate successively, and this first and second ejector retainner plate is fixedly connected, also is fixed with first thimble on this first ejector retainner plate, and this first thimble, one end activity is passed male model plate, male model benevolence and male model and gone into son, and cooperating this male model to go into son, mother module core shaped article, this male model is gone into son and then is movably set on this male model benevolence.This third and fourth ejector retainner plate is fixedly connected, is fixed with second thimble on the 3rd ejector retainner plate, and this first and second ejector retainner plate, male model plate and male model benevolence are passed in this second thimble, one end, and fixedly connected this male model is gone into son.In addition, also be articulated with spill spin block between this third and fourth ejector retainner plate, also be fixed with briquetting on this male model plate, this briquetting one end passes this first and second ejector retainner plate, and can contact on this spill spin block.

Preferable, the invention provides a kind of secondary ejecting mechanism, wherein, this spill spin block has two salient points, and when this briquetting contacted at this spill spin block one salient point, another salient point then contacted on this second top board.

The present invention can eject the product after the moulding smoothly, and it is white to avoid product to be pushed up, and pushes up the generation of bad phenomenon such as protruding, has preferable practical value.

Description of drawings

Fig. 1 is the mould matched moulds schematic diagram of one embodiment of the invention;

Fig. 2 is the mould die sinking schematic diagram of one embodiment of the invention.

The specific embodiment

State with other purpose, feature and advantage and can become apparent on the present invention for allowing, embodiment more cited below particularly, and cooperate appended graphicly, be described in detail below.

See also shown in Figure 1, the present invention is applied in the mould, it comprises first, second, third and fourth

ejector retainner plate

1100,1200,1300,1400, and this first, second, third and fourth

ejector retainner plate

1100,1200,1300,1400 is movably set between mould male model plate 1000 and the bottom plate 4000 successively.This first and second

ejector retainner plate

1100,1200 is fixedly connected, also be fixed with first thimble 1110 on this first ejector retainner plate 1100, these first thimble, 1,110 one end activities are passed male model plate 1000, male model benevolence 2000 and male model and are gone into son 2100, and this first thimble 1110 cooperates this male model to go into son 2100, mother module core 3000 shaped articles 6000, and this male model is gone into son 2100 and is movably set on this male model benevolence 2000.

This third and fourth

ejector retainner plate

1300,1400 is fixedly connected, be fixed with second thimble 1310 on the 3rd ejector retainner plate 1300, this first and second

ejector retainner plate

1100,1200, male model plate 2000 and male model benevolence 2100 are passed in these second thimble, 1,310 one ends, and fixedly connected this male model is gone into son 2100.In addition, also be articulated with spill spin block 1320 between this third and fourth

ejector retainner plate

1300,1400, in present embodiment, this spill spin block 1320 has two salient points, also be fixed with briquetting 1500 on this male model plate 1000, these briquetting 1,500 one ends pass this first and second

ejector retainner plate

1100,1200, and can contact at this spill spin block 1320 wherein on the salient point.

When this mould die sinking, as shown in Figure 2, this mother module core 3000 rises, one injector push rod 5000 will be conflicted and jack-up the 4th ejector retainner plate 1400, and so, this first, second, third and fourth

ejector retainner plate

1100,1200,1300,1400 will rise simultaneously, at this moment, because these second thimble, 1310 fixedly connected these male models are gone into son 2100, so this male model is gone into son 2100 and also will be risen simultaneously; When this third and fourth

top board

1300,1400 rises to a certain degree, this briquetting 1500 will contact on these spill spin block 1,320 one ends, at this moment, this third and fourth

ejector retainner plate

1300,1400 will at the uniform velocity rise, then continue to rise and jack-up second ejector retainner plate 1200 in these spill spin block 1320 the other end, so, this first thimble 1110 will continue to rise, thereby this first thimble 1110 will eject product 6000.

The present invention utilize second thimble 1310 eject earlier male model go into the son 2100, in this process, product 6000 will diminish with the mucous membrane power that male model is gone into son 2100, then utilize first thimble 1110 to eject product 6000 again, can eject product 6000 this moment smoothly, avoid product 6000 white, push up the generation of bad phenomenon such as protruding, have preferable practical value by the top.

The above only is a preferable possible embodiments of the present invention, is not so limits to claim of the present invention, so the equivalent structure that every utilization specification of the present invention and accompanying drawing content are done changes, all is contained in protection scope of the present invention.
