Abstract

The utility model discloses an anti-release structure for a positioning pin of a pin. The anti-release structure consists of an upper template, a lower template, an upper cavity fixed on the upper template and a lower cavity fixed on the lower template. Moreover, the upper cavity and the lower cavity are equipped with a fist positioning slot and a second positioning slot respectively, and a positioning pin is inserted in the corresponding first positioning slot and second positioning slot. In addition, a butting section is fixed in the first positioning slot and butts the positioning pin. With the butting section butting the positioning pin, the structure can not only prevent the positioning pin from loosening or even falling off from the first and second positioning slots due to the long time of working vibration and thus avoid that a product or the lower cavity is pressed and destroyed when the positioning pin loosens or falls off. The anti-release structure is provided with the relatively good practical value.

Description

Mould alignment pin anti-loose structure

Technical field

The utility model relates to a kind of mould alignment pin anti-loose structure.

Background technology

In mould in the past, as shown in Figure 1, the alignment pin 1100 of upper cores 1000 does not take to prevent the measure that gets loose, therefore following problem often appears after mould puts into production: 1. because mould long-term work vibrations, the alignment pin 000 of upper cores 1000 gets loose easily, if deviate from upper cores 1000 surfaces, alignment pin 1100 can weigh product 3000 wounded; 2. after alignment pin 1100 became flexible, because the mould judder, alignment pin 1100 can come off from upper cores 1000 and fall into down die 4000, when operating personnel in time do not find, punch press continues motion, and die 4000 was forced out pit under can cause this moment, even cracking is scrapped.

Summary of the invention

In view of the above problems, the utility model purpose is to provide a kind of mould alignment pin anti-loose structure, and it can prevent that this alignment pin from getting loose, thereby can avoid product or the mould die is damaged by pressure by this alignment pin.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of mould alignment pin anti-loose structure, it comprises upper and lower template and is separately fixed at upper and lower die on this upper and lower template, also be respectively arranged with corresponding first and second locating slot in this upper cores and this cope match-plate pattern, be inserted with alignment pin in this corresponding first and second locating slot, also be fixed with the contact part in first locating slot of this upper cores, this contact part contacts on this alignment pin.

So, when this alignment pin is inserted in first and second locating slot of upper cores, cope match-plate pattern, also be fixed with the contact part in first locating slot of this upper cores, contact on this alignment pin by this contact part, can prevent that this mould is owing to the long-term work vibrations get loose this alignment pin from first and second locating slot, and then can avoid the product that causes owing to getting loose of this alignment pin or descend die to be damaged by pressure, have preferable practical value.

Fig. 2 is the utility model mould alignment pin anti-loose structure schematic diagram.

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 comprises,

lower bolster

2000,5000 and be fixed on this, lower bolster 2000, on on 5000, following die 1000,6000, on being somebody's turn to do, following die 1000,6000 cooperate shaped article 3000, offer corresponding first in this upper cores 1000 and this cope match-plate pattern 2000, two locating

slots

1200,2200, this upper cores 1000 offers corresponding 2 first locating slots 1200, offer 2 second locating slots 2200 of corresponding these 2 first locating slots 1200 in this cope match-plate pattern 2000, this two alignment pin 1100 is inserted in pairing first respectively, two locating slots 1200, in the time of in 2200, also be fixed with a contact part respectively in this 2 first locating slot 1200.

In present embodiment, wherein a contact part is a set screw 1310, this set screw 1310 is bolted in wherein in one first locating slot 1200, and this set screw 1310 will contact at wherein on the alignment pin 1100, and another contact part is a spring plug 1320, this spring plug 1320 snaps into wherein in one first locating slot 1200, and this spring plug 1320 will contact on another alignment pin 1100.

So, this two alignment pin 1100 has had the conflict restriction of this set screw 1310, spring plug 1320, even under the vibrations of this mould long-term work, this two alignment pin 1100 can not get loose from this first and second locating

slot

1200,2200 even come off yet, and then and then can avoid having preferable practical value owing to the getting loose or the product 3000 that causes or die 6000 is damaged by pressure down of coming off of this alignment pin 1100.

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.

Claims

1. mould alignment pin anti-loose structure, it comprises upper and lower template and is separately fixed at upper and lower die on this upper and lower template, also be respectively arranged with corresponding first and second locating slot in this upper cores and this cope match-plate pattern, be inserted with alignment pin in this corresponding first and second locating slot, it is characterized in that, also be fixed with the contact part in first locating slot of this upper cores, this contact part contacts on this alignment pin.
