Abstract

A mold opening delaying mechanism is applied to a mold. The mold opening delaying mechanism comprises a deviating block, a stopping block, a locking block and a pull rod. One end of the deviating block is fixed on one side of a female mold board, the deviating block is provided with a holding tank, and a protruding block is arranged at the end of the deviating block provided with the holding tank. One end of the stop block is disposed in a push plate, the other end of the stop block stretches out of the push plate, and an elastic element is placed between the stop block and the push plate. One end of the locking block is fixed on one side of a male mold board, the other end of the locking block is placed in the holding tank, a hook block is arranged at the end of the locking block provided with the holding tank, and the hook block clamps the stopping block. The pull rod passes through a lower fixing plate, the male mold board and the push plate, one end of the pull rod is fixed in a female mold kernel, and the other end of the pull rod is arranged in the push plate in a clamping mode to fix the push plate at the time of mold opening. According to the mold opening delaying mechanism, when tube products are produced, the stopping block is deviated through the deviating block to control sequence of mold opening. Besides, the mold opening delaying mechanism can save a male mold kernel, a corner cushion and an ejector mechanism, and is simple in structure.

Description

Postpone die opening mechanism

[technical field]

The utility model relates to a kind of mold mechanism, is specifically related to the delay die opening mechanism of four die sinkings of a kind of solution order.

[background technology]

In the production of plastic cement products, sidewall is very high around some classes and some shell series products, middle body seldom, the maximum place of sticking to mould power just around side-walls, get final product if very little cylinder ejects with the sleeve of routine; If the tube series products bigger or square or during irregular body; With the conventional row's of the being not easy to thimble that ejects; The mould of producing this series products is more suitable for adopting push pedal to eject, yet this type of mould has four die sinkings action, and four die sinkings need successively be arranged properly in proper order.

In view of above problem, be necessary to provide a kind of delay die opening mechanism in fact, this delay die opening mechanism can be good at solving the order of four die sinkings.

[specific embodiment]

Please consult Fig. 1, Fig. 2 and Fig. 3 simultaneously; In present embodiment; The delay die opening mechanism of the utility model; It is applied in the mould, and this mould comprises from top to bottom successively: upper mounted plate 100, stripper plate 110, caster 120, mother module core 130, male model are gone into son 140, push pedal 150, male model plate 160 and bottom plate 170, and this delay die opening mechanism comprises:

Shifting block 200, one of which end are fixed in said caster 120 1 sides, and this shifting block 200 is provided with holding tank 220, and this end that is provided with holding tank 220 is provided with projection 210, and this projection 210 is provided with first inclined-plane 211;

Block 300, one of which end are located in the said push pedal 150, and it is located therein for this block 300 to be provided with corresponding spatial accommodation in this push pedal 150; These block 300 other ends stretch out this push pedal 150; This end that stretches out push pedal 150 is provided with second inclined-plane 330, and this second inclined-plane 330 is identical with 211 angles of inclination, said first inclined-plane, and 150 of this block 300 and this push pedals are provided with flexible member 310 in horizontal direction; This flexible member 310 is a spring in present embodiment; Said shifting block 200 is stirred this block 300 through projection 210 it is returned in the push pedal 150 fully when the mould die sinking, thereby makes the mould die sinking, and this block 300 is provided with draw-in groove 320 in addition; 150 of this draw-in groove 320 and this push pedals are provided with limited screw 321 with spacing this block 300 in vertical direction, prevent that this block 300 breaks away from from push pedal 150;

Latch segment 400; The one of which end is fixed in said male model plate 160 1 sides, and the other end is located in the said holding tank 220, and this end of being located at holding tank 220 is provided with and colludes piece 410; This colludes piece 410 and blocks said block 300, and this colludes piece 410 and these block 300 disengagings when the mould die sinking;

Pull bar 500; It passes from said bottom plate 170 and male model plate 160 and push pedal 150; Being provided with corresponding spatial accommodation in this bottom plate 170 and male model plate 160 and the push pedal 150 therefrom passes for this pull bar 500; And these pull bar 500 1 ends are fixed in the said mother module core 130, thereby these pull bar 500 other ends are fastened on fixedly push pedal 150 in the push pedal 150 during the mould die sinking, make its stop motion.

When the mould die sinking; Die sinking for the first time and die sinking for the second time are the same with common three template dies; Stripper plate 110 was opened with caster product 600 and runner is separated in 120 minutes during i.e. die sinking for the first time, and stripper plate 110 was opened with upper mounted plate runner is peeled off from mould in 100 minutes during die sinking for the second time.

See also shown in Figure 4; During mould die sinking for the third time, male model plate 160 continues motion, thus since the piece 410 that colludes of latch segment 400 blocked block 300 and locked together with block 300; Male model plate 160 and push pedal 150 can not be separated; Male model plate 160 is moved away from caster 120 with push pedal 150, and the package power of product 600 was opened product 600 and mother module core in 130 minutes to stay male model goes on the son 140, accomplishes the branch mould of product 600.

See also shown in Figure 5ly, during the 4th die sinking of mould, male model plate 160 continues motion with push pedal 150, and when pull bar 500 other ends were stuck in the push pedal 150, push pedal 150 was accomplished movement travels and stop motion; Because the effect of cooperatively interacting on first inclined-plane 211 and second inclined-plane 330, shifting block 200 projections 210 are stirred block 300, and flexible member 310 is compressed, and block 300 returns in the push pedal 150 under the toggle action of the projection 210 of shifting block 200 fully; And the piece 410 that colludes of latch segment 400 no longer sticks block 300, and latch segment 400 and block 300 are broken away from, and male model plate 160 was opened with push pedal in 150 minutes; Male model plate 160 continues motion after male model is gone into the son 140 and the product 600 complete demouldings, accomplishes the 4th die sinking of mould; Product 600 after going into son 140 disengagings with male model takes out product 600.
