Description

Postpone die opening mechanism

[technical field]

The present invention relates to a kind of mold mechanism, be specifically related to a kind of delay die opening mechanism solving four die sinkings order.

[background technology]

In the production of plastic cement products, some classes and some shell series products surrounding sidewalls are the highest, and middle body is little, viscous The place of mould power maximum is just in surrounding side-walls, if the sleeve of the least cylinder routine ejects；If cylinder series products During bigger or square or irregular body, it is not easy to arrange thimble with conventional ejecting, produces the mould of this series products Tool is more suitable for using ejecting push plate, but this type of mould has four die sinking actions, and four die sinkings order needs successively to arrange properly.

In view of problem above, being necessary that providing a kind of postpones die opening mechanism in fact, this delay die opening mechanism can be good at solving The certainly order of four die sinkings.

[summary of the invention]

Therefore, it is an object of the invention to provide a kind of delay die opening mechanism, this delay die opening mechanism can be good at solving The order of four die sinkings.

In order to achieve the above object, the delay die opening mechanism of the present invention, it is applied in mould, this mould is the most successively Including: upper mounted plate, stripper plate, caster, mother module core, male die insert, push pedal, male template and bottom plate, this delay die sinking Mechanism includes:

[detailed description of the invention]

Please refer to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, the delay die opening mechanism of the present invention, it is applied to mould In, this mould includes the most successively: upper mounted plate 100, stripper plate 110, caster 120, mother module core 130, male die insert 140, push pedal 150, male template 160 and bottom plate 170, this delay die opening mechanism includes:

Shifting block 200, its one end is fixed on described caster 120 side, and this shifting block 200 is provided with holding tank 220, is provided with receiving This end of groove 220 is provided with projection 210, and this projection 210 is provided with the first inclined-plane 211；

Block 300, its one end is located in described push pedal 150, is provided with the corresponding space that accommodates for this gear in this push pedal 150 Block 300 is located therein, and this block 300 other end stretches out this push pedal 150, and this end stretching out push pedal 150 is provided with the second inclined-plane 330, This second inclined-plane 330 is identical with described first angle of inclination, inclined-plane 211, and in horizontal direction between this block 300 and this push pedal 150 Being provided with flexible member 310, in the present embodiment, this flexible member 310 is spring, and when mould die sinking, described shifting block 200 passes through Projection 210 stirs this block 300 makes it be withdrawn completely in push pedal 150, so that mould die sinking, additionally sets on this block 300 There is draw-in groove 320, between this draw-in groove 320 and this push pedal 150, be provided with limited screw 321 with this block 300 spacing in vertical direction, anti- Only this block 300 departs from from push pedal 150；

Latch segment 400, its one end is fixed on described male template 160 side, and the other end is located in described holding tank 220, and This end being located at holding tank 220 is provided with hook block 410, and this hook block 410 blocks described block 300, this hook block 410 when mould die sinking Depart from this block 300；

Pull bar 500, it passes from described bottom plate 170 and male template 160 and push pedal 150, this bottom plate 170 and Male template 160 and push pedal 150 are provided with the corresponding space that accommodates extend there through for this pull bar 500, and this pull bar 500 one end is solid In described mother module core 130, during mould die sinking, this pull bar 500 other end is fastened in push pedal 150 thus fixing push pedal 150, Make its stop motion.

When mould die sinking, die sinking for the first time and second time die sinking, as common three template dies, are shelled during die sinking i.e. for the first time Flitch 110 separates with caster 120 and is separated with runner by product 600, for the second time stripper plate 110 and upper mounted plate 100 during die sinking Separately runner is peeled off from mould.

Referring to shown in Fig. 4, during mould third time die sinking, male template 160 continues motion, due to the hook block of latch segment 400 410 are seized block 300 thus lock together with block 300, make male template 160 and push pedal 150 not to separate, make male template 160 move away from caster 120 together with push pedal 150, and the package power of product 600 makes product 600 separately stay with mother module core 130 On male die insert 140, complete point mould of product 600.

Referring to shown in Fig. 5, during the 4th die sinking of mould, male template 160 continues motion with push pedal 150, when pull bar 500 is another When one end is stuck in push pedal 150, push pedal 150 completes movement travel and stop motion；Due to the first inclined-plane 211 and the second inclined-plane The effect of cooperating of 330, shifting block 200 projection 210 stirs block 300, and flexible member 310 is compressed, and block 300 is at shifting block Under the toggle action of the projection 210 of 200, it is withdrawn completely in push pedal 150；And the hook block 410 of latch segment 400 no longer sticks block 300, make latch segment 400 and block 300 depart from, male template 160 is separated with push pedal 150；Male template 160 continues motion until male model After entering son 140 and the complete demoulding of product 600, complete the 4th die sinking of mould；Product 600 will after departing from male die insert 140 Product 600 takes out.
