Abstract

The utility model discloses a die with an auxiliary shutter ejection mechanism. An upper ejection plate and a lower ejection plate, which are connected fixedly, are arranged flexibly between an upper fixing plate and a cavity plate. An ejection pin is fixed on the upper ejection plate and goes flexibly through the cavity plate and a cavity insert to help a core insert shape a product. In addition, a pull pin is also fixed on the upper ejection plate, goes through the end section of the cavity plate and is connected fixedly with a shutter. A core plate is equipped with a groove matching the shutter. With the pull pin and the shutter arranged on the upper ejection plate and the cooperation of the shutter and the groove, the ejection pin can be ejected in time to separate the product from the cavity insert and thus prevent the product from being ejected by the ejection pin. Thus, the die is provided with the relatively good practical value.

Description

The mould of the auxiliary ejecting mechanism of tool shutter

Technical field

The utility model relates to a kind of mould structure, relates in particular to the mould of the auxiliary ejecting mechanism of a kind of tool shutter.

Background technology

When doing master mold body finished product how, situation for fear of the glutinous master mold of product, as shown in Figure 1, we are movably set with the following liftout plate 1100 and the upper ejector plate 1200 of fixedlying connected between caster 1000 and upper mounted plate 2000, this upper ejector plate 1200 is provided with elastic parts 1400 with this upper mounted plate 2000, these elastic parts 1,400 one ends contact on this upper ejector plate 1200, the other end then contacts on this upper mounted plate 2000, this time liftout plate 1100 also is fixed with a thimble 1300, and this thimble 1300 passes this caster 1000 with mother module core 3000 and cooperate this mother module core 3000 shaped articles 4000, when this mould die sinking, these male model plate 5000 relative these casters 1000 move down, this male model benevolence 6000 is separated with this mother module core 3000, this time liftout plate 1100 is under the effect of the elastic-restoring force of this elastic parts 1400, to drive thimble 1300 relative these mother module cores 3000 descends, this product 4000 thereby this mother module core 3000 will be conflicted, and then this product 4000 is separated with this mother module core 3000.

Yet if this elastic parts 1400 can not be in time with this time liftout plate 1100 tops down, this thimble 1300 just can not in time eject this product 4000, and this product 4000 can not be pushed up timely to male model benevolence 6000, and this thimble 4000 can be white with these product 4000 tops.

Summary of the invention

In view of the above problems, the utility model purpose is to provide the mould of the auxiliary ejecting mechanism of a kind of tool shutter, and it can guarantee that this product can be pushed up timely to male model benevolence, thereby can prevent that this product is white by the thimble top.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: the mould of the auxiliary ejecting mechanism of a kind of tool shutter, be movably set with the upper and lower liftout plate of fixedlying connected between this mould upper mounted plate and the caster, be fixed with a thimble on this upper ejector plate, this thimble activity is arranged in this caster, the mother module core to cooperate this mother module core, male model benevolence shaped article, this upper ejector plate also is fixedly connected with one and draws pin, this end of drawing pin to pass this caster also is fixedly connected with a shutter, and this male model plate is provided with in order to cooperate the groove of this shutter.

Preferable, the utility model provides the mould of the auxiliary ejecting mechanism of a kind of tool shutter, wherein, is fixed with a guide pillar between this upper mounted plate and this caster, and this upper and lower liftout plate pivot bush unit is on this guide pillar.

Preferable, the utility model provides the mould of the auxiliary ejecting mechanism of a kind of tool shutter, wherein, also is socketed with an elastic parts on this guide pillar, and this elastic parts one end contacts on this upper mounted plate, and the other end then contacts on this upper ejector plate.

Preferable, the utility model provides the mould of the auxiliary ejecting mechanism of a kind of tool shutter, wherein, also is provided with air drain on this male model plate, and this air drain connects this bottom portion of groove.

Than prior art, the utility model draws pin and shutter by being provided with on upper ejector plate, by cooperating of this shutter and groove, guarantee that this thimble can in time eject, so that this product separates with this mother module core, and then avoid this product white, have preferable practical value by the thimble top.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also shown in Figure 2, in present embodiment, this mould upper mounted plate 2000 and caster 1000 be movably set with fixedly connected on, following

liftout plate

1200,1100, also be provided with a guide pillar 1500 between this upper mounted plate 2000 and this caster 1000, on being somebody's turn to do, following

liftout plate

1200,1100 pivot bush units are on this guide pillar 1500, also be socketed with an elastic parts 1400 on this guide pillar 1500, in present embodiment, this elastic parts 1400 is springs, these elastic parts 1,400 one ends contact on this upper mounted plate 2000, the other end then contacts on this upper ejector plate 1200, this upper ejector plate 1200 also is fixed with a thimble 1300, these thimble 1300 activities are arranged in this caster 1000, in the mother module core 3000 to cooperate this male model benevolence 6000, mother module core 3000 shaped articles 4000, in addition, this upper ejector plate 1200 also is fixed with one and draws pin 7000, this end of drawing pin 7000 activities to pass this caster 1000 also is fixedly connected with a

shutter

7100,5000 of this male model plates are provided with the groove 5100 in order to cooperate this shutter 7100, in present embodiment, also be provided with air drain 5200 on this male model plate 5000, this air drain 5200 connects these groove 5100 bottoms, discharges via this air drain 5200 so that this shutter 7100 snaps in the compressed air that produces in this groove 5100.

So, when this mould die sinking, as shown in Figure 3, these male model plate 5000 relative these casters 1000 move down, this male model benevolence 6000 is separated with this mother module core 3000, because this shutter 7100 is fastened in this groove 5100, this male model plate 5000 moves down and then will drive this and draw pin 7000, thereby this draws pin 7000 to drive this thimble 1300 by this upper ejector plate 1200 and moves down, in addition, this time liftout plate 1100 also will drive these thimble 1300 relative these mother module cores 3000 and move down under the effect of the elastic-restoring force of this elastic parts 1400, this product 4000 thereby this thimble 1300 will be conflicted, and then this product 4000 is separated with this mother module core 3000.

Than prior art, the utility model draws pin 7000 and shutter 7100 by being provided with on upper ejector plate 1200, by cooperating of this shutter 7100 and groove 5100, guarantee that this thimble 1300 also can in time eject under the situation that elastic parts 1400 lost efficacy, so that this product 4000 separates with this mother module core 3000, and then avoid this product 4000 white by thimble 1300 tops, have preferable practical value.

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