Abstract

The utility model discloses an automatic type composite die, which sequentially comprises an upper die frame plate, an upper die fixing plate, a concave die, a discharging plate, a lower die base plate and a lower die frame plate and is characterized in that a material pushing block is arranged in the concave die, a push rod is arranged in the upper die fixing plate, the lower end of the push rod extends to be contacted with the material pushing block, the upper end of the push rod extends into the upper die frame plate to be contacted with a knockout plate in the upper die frame plate, the top wall of the knockout plate is contacted with a knockout rod, and the upper end of the knockout rod extends to the upper portion of the upper die frame plate. The automatic type composite die is low in labor intensity, safe in use and high in punching efficiency.

Description

A kind of automatic type composite die

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of automatic type composite die.

Background technology

Rise day by day in the status of mould industry in national economy; Mould is industrial fundamental technology equipment; In products such as electronics, automobile, motor, electrical equipment, instrument, household electrical appliances and communication, 60%～80% parts all rely on die forming, and the height of die quality directly determines the height of product quality; Therefore, mould is called as " mothers of all trades ".Mould is again " a benefit amplifier ", with the value of the final products of die production tens times, hundreds of times of mould self-value often.

At present, mould generally is made up of punch and die, and punch press often needs the operator manually the product on the punch to be taken off after one stroke is accomplished, and this kind mode not only security is lower, also causes bigger, the die-cut efficient of operator's labour intensity lower simultaneously.

The utility model content

The utility model technical problem to be solved provides the higher automatic type composite die of low, safe in utilization, the die-cut efficient of a kind of labour intensity.

For solving the problems of the technologies described above; The utility model provides a kind of automatic type composite die; Comprise patrix frame plate, upper mould fixed plate, die, stripper, counterdie backing plate and counterdie frame plate successively, be provided with ejection block in the said die, be provided with push rod in the said upper mould fixed plate; The lower end of said push rod extends to said ejection block and contacts; The upper end of said push rod extends in the said patrix frame plate and with the knockout plate that is arranged in said patrix frame plate and contacts, and the roof of said knockout plate contacts with knockout rod, and the upper end of said knockout rod extends to the top of said patrix frame plate.

Be disposed with upper die plate between said patrix frame plate and the said upper mould fixed plate, be provided with the counterdie fixed head between said stripper and the said counterdie backing plate.

Compared with prior art, the beneficial effect of the utility model is:

Because a kind of automatic type composite die of the utility model is disposed with knockout rod, knockout plate, push rod and ejection block; Wherein knockout rod, knockout plate, push rod and ejection block contact setting successively; Under the effect of punch press vibrations, force knockout rod to the lower compression knockout plate and drive ejection block downwards through push rod product is ejected from die in actual the use; Need not the operator and take out product by hand; Not only eliminated potential safety hazard, also improved operating efficiency simultaneously, so low, safe in utilization, the die-cut efficient of the utility model labour intensity is higher.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and practical implementation the utility model is explained further details

Referring to shown in Figure 1, a kind of automatic type composite die comprises patrix frame plate 10, upper die plate 12, upper mould fixed plate 14, die 16, stripper 18, counterdie fixed head 20, counterdie backing plate 22 and counterdie frame plate 24 successively; Wherein in die 16, be provided with ejection block 26; In upper mould fixed plate 14, be provided with push rod 28, the lower end of push rod 28 extends to ejection block 26 and contacts, and the upper end of push rod 28 extends in the patrix frame plate 10 and with the knockout plate that is arranged in patrix frame plate 10 30 and contacts; Roof at knockout plate 30 contacts with knockout rod 32; The upper end of this knockout rod 32 extends to the top of patrix frame plate 10, and knockout rod 32 contacts with the percussion mechanism of punch press in actual the use, and knockout rod 32 forces it to lower compression knockout plate 30 and through the push rod 28 downward ejection block 26 that drive product to be ejected from die 16 under the effect of punch press vibrations after the moulds open; Need not the operator and take out product by hand; Not only eliminate potential safety hazard, reduced labour intensity, also improved operating efficiency simultaneously.

In sum, low, safe in utilization, the die-cut efficient of the utility model labour intensity is higher.

The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.

Claims

1. automatic type composite die; Comprise patrix frame plate, upper mould fixed plate, die, stripper, counterdie backing plate and counterdie frame plate successively; It is characterized in that: be provided with ejection block in the said die; Be provided with push rod in the said upper mould fixed plate, the lower end of said push rod extends to said ejection block and contacts, and the upper end of said push rod extends in the said patrix frame plate and with the knockout plate that is arranged in said patrix frame plate and contacts; The roof of said knockout plate contacts with knockout rod, and the upper end of said knockout rod extends to the top of said patrix frame plate.

2. a kind of automatic type composite die according to claim 1 is characterized in that: be disposed with upper die plate between said patrix frame plate and the said upper mould fixed plate, be provided with the counterdie fixed head between said stripper and the said counterdie backing plate.
