Description

Taper pin mechanism

[technical field]

The utility model relates to a kind of taper pin mechanism, particularly a kind ofly can strengthen the taper pin mechanism that taper pin intensity is convenient to repair a die and is established change.

[background technology]

In existing mould is produced, some products often come moulding by taper pin, when running into the very little structure in some formed product mould spaces then, the taper pin of using is little and the situation that length is very long in cross section often, will cause taper pin insufficient strength in mould is produced like this, fracture easily, thus production has brought a lot of troubles and inconvenience to mould, in addition, also have a kind of taper pin mechanism to constitute by taper pin and thimble.Particularly, existing taper pin mechanism is as follows:

Fig. 1 illustrates the structural representation of first kind of existing taper pin mechanism.

With reference to shown in Figure 1, existing taper pin mechanism, it is applied to during a mould produces, and this taper pin mechanism comprises: taper pin seat 10; Taper pin 11, the one end is located at the end that above-mentioned taper pin seat 10 has dowel hole 101 by an alignment pin 12, and the other end penetrates to be located in the male model plate and is used for shaped article.

Taper pin 11 cross sections hour also need to add a hole that is not less than Φ 2.5mm in the above-mentioned taper pin mechanism, be easy to rupture, for ease of installing, taper pin need pass the male model plate, taper pin length must be accomplished very long, and taper pin is yielding, job insecurity, thereby production has brought a lot of troubles to mould, has also caused the waste on the cost.

Fig. 2 illustrates the structural representation of second kind of existing taper pin mechanism.

With reference to shown in Figure 2, existing taper pin mechanism, it is applied to during a mould produces, and this taper pin mechanism comprises: taper pin 20, one end are provided with one first hook 201; Thimble 21, its end that cooperates with above-mentioned taper pin 20 are provided with one second hook 211, and the other end is provided with countersunk head 212, and in embodiment, this countersunk head 212 needs the pin limit to be located in the upper ejector plate.

Need first hook 201 and second to link up with 211 because of taper pin 20 during with thimble 21 in the above-mentioned taper pin mechanism, above-mentioned two hook junction intensity differences, fracture easily, two hook junctions are relative motions, matching can not tension, the while excesssive gap also can add glue on finished product or taper pin can't withdraw from, machining accuracy is very high, and need to sell the frontier defense spline moving at countersunk head 212 places, thereby makes the Mould Machining operation increase, cost raises, this is external to repair a die to establish often taper pin reprocessing in the change, need taper pin is split out from mould bases, so just need pull down fixed head, liftout plate will spend great amount of manpower and time.

[summary of the invention]

In view of this, the purpose of this utility model is to provide a kind of taper pin mechanism, and this taper pin mechanism uses die space little, and processing is simple, the intensity height, and be convenient to assembling, installation and the dismounting of mould.

For achieving the above object, the utility model provides a kind of taper pin mechanism, and it is applied to during a mould produces, and this mould comprises: caster, male model plate, upper ejector plate, liftout plate and fixed head down, and this taper pin mechanism comprises:

Taper pin, it is located in the above-mentioned male model plate, this taper pin one end face and above-mentioned mother module core breaking, and a side of this taper pin is provided with a chute;

Thimble, one end are located in the above-mentioned upper ejector plate, and the other end is located in the above-mentioned male model plate and with the other end of taper pin and is contacted;

Backing pin, it is located in the above-mentioned male model plate, and an end is located in the chute of above-mentioned taper pin.

Compared to prior art, taper pin of the present utility model mechanism is in mould is produced, and the free space to mould when running taper pin requires little, and taper pin can be accomplished very short intensity height, and easy fracture is not processed simple, it is good that the standard thimble need not to reprocess intensity, is convenient to assembling, installation and the dismounting of mould.

For the purpose of this utility model, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

[specific embodiment]

With reference to Fig. 3 and shown in Figure 4, taper pin of the present utility model mechanism, it is applied to during a mould produces, and this mould comprises: caster 301, male model plate 302, upper ejector plate 303, liftout plate 304 and fixed head 305 down, this taper pin mechanism comprises:

Taper pin 31, it is located in the above-mentioned male model plate 302, these taper pin 31 1 end faces and 3011 breakings of above-mentioned mother module core, and a side of this taper pin 31 is provided with a chute 311, the backing pin 33 that is provided with in this chute 311 and the mould matches, and ejects after die sinking in the process, and taper pin 31 can be ejected by thimble 32, after ejection stroke finished, backing pin 33 prevented that in chute 311 taper pin 31 from skidding off.In other embodiment, this chute 311 and a block interact;

Thimble 32, one end are located in the above-mentioned upper ejector plate 303, and the other end is located in the above-mentioned male model plate 302 and with the other end of taper pin 31 and is contacted.

In present embodiment, countersunk head 321 on the above-mentioned thimble 32 need not the pin limit and just can directly be located in the upper ejector plate 303, and taper pin 31 need not to make the mutual hook that engages with the junction of thimble 32, and then avoided the junction intensity difference, the problem of easy fracture is during die sinking, liftout plate drives thimble 32 and promotes taper pin 31 motions, finish eject after, caster 301 is simultaneously closed with male model plate 302, caster 301 promotes taper pins 31 returns.The taper pin insufficient strength can not take place and the phenomenon that ruptures in the strength-enhanced of taper pin in the utility model taper pin mechanism in mould production, simultaneously, this taper pin mechanism processing is simple, is convenient to assembling, installation and the dismounting of mould.
