Abstract

The utility model discloses a replacement device of an ejector pin or insert pin applied on a mould, which comprises a bottom board, and a pressing block; the bottom board is provided with a pinhole for the ejector pin or the insert pin to pass through; the pressing block is fixed on the bottom board by screws and covers the pinhole; the utility model is characterized in that the pressing block is provided with a gap; the screws comprises a first screw and a second screw; the first screw is arranged on the bottom board through a screw hole on the pressing block; while the pressing block is arranged on the bottom board by the second screw in a dismountable way through the gap. Compared with the prior art, the utility model has the advantages that: when the insert pin or the ejector pin is needed to be replaced, the pressing block can rotate by 90 degrees along one pivot only by unscrewing the screws, thus being capable of quickly replacing without dismounting the whole pressing block for replacement, thereby improving the working efficiency; besides, the screws and the pressing block are not needed to be dismounted completely, thus greatly reducing the possibility of losing.

Description

Be applied to more changing device of department's pin of mould or pin

Technical field

The utility model relates to the more changing device of taking charge of pin or pin in a kind of mould.

Background technology

In the mould of many moneys of mould product, need the many moneys of outfit department pin, pin to adapt to many moneys product, during use, department's pin, pin generally are to be fixed on the base plate by two countersunk head screws with briquetting, when changing, two screws need be screwed out, take out briquetting again, extraction department pin, pin are changed then, obviously so more time-consuming trouble of way, and the number of Geng Huaning is bigger if desired, operating efficiency will be seriously influenced, be difficult to satisfy the needs of reality, in addition, also may run into briquetting and screw is obscured, situation such as lose, and then influence the progress of work.

The utility model content

Technical problem to be solved in the utility model is that more changing device of department's pin that a kind of replacing is applied to mould easily or pin is provided at the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of department's pin that is applied to mould or pin be changing device more, comprise base plate and briquetting, have on this base plate for taking charge of the pin hole that pin or pin pass through, aforesaid briquetting is fixed on the base plate and with aforementioned pin hole by screw and covers, it is characterized in that described briquetting has a breach, described screw comprises first screw and second screw, this first screw is located on the described base plate by the screw on the described briquetting, this second screw then is located at described briquetting detached type on the described base plate by aforesaid breach, described first screw and second screw are in for not screwing under the state, and described briquetting breaks away from described second screw around described screw and described breach and rotates.

As preferably, described briquetting is that two ends have circular-arc bar blocks, and described breach is opened in the first end of described briquetting, described screw then be located at aforementioned first end opposite second end on.

Compared with prior art, advantage of the present utility model is: when needing to change pin or department's pin, as long as unclamp screw a little, briquetting just can revolve around a fulcrum and turn 90 degrees, so just can change apace, and need not whole briquetting is disassembled replacing, improve operating efficiency; In addition, screw and briquetting need not to unload down fully, have significantly reduced the possibility of losing.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment: referring to figs. 1 to shown in Figure 5, department's pin that is applied to mould in the present embodiment or pin more changing device comprise base plate 1 and briquetting 2, have on the base plate 1 for taking charge of the pin hole 11 that pin or pin pass through, briquetting 2 is fixed on the base plate 1 by screw and pin hole 11 covers.

First end 23, one screws 22 that the bar blocks that briquetting 2 is circular-arc for two ends have, a breach 21 are opened in briquetting be located at first end 23 opposite second end 24 on.Screw comprises first screw 31 and second screw 32, first screw 31 is located on the base plate 1 by the screw on the briquetting 22, second screw 32 is located at the briquetting detached type on the base plate 1 by breach 21, first screw 31 and second screw 32 are in for not screwing under the state, and briquetting 1 breaks away from second screws 32 around screw 22 and breach 21 and rotates.Like this, just can change pin or department's pin apace, and need not whole briquetting 2 is disassembled replacing, improve operating efficiency.

With reference to shown in Figure 6, be the application of embodiment on mould, as shown in the figure, die ontology 10 is provided with and inserts 6, inserts 7, push pedal 9 and base plate 1, and base plate 1 is provided with briquetting 2, and pin 8 and department's pin 4 are located on the die ontology 10 by briquetting 2.

Claims

1, a kind of department's pin that is applied to mould or pin be changing device more, comprise base plate and briquetting, have on this base plate for taking charge of the pin hole that pin or pin pass through, aforesaid briquetting is fixed on the base plate and with aforementioned pin hole by screw and covers, it is characterized in that described briquetting has a breach, described screw comprises first screw and second screw, this first screw is located on the described base plate by the screw on the described briquetting, this second screw then is located at described briquetting detached type on the described base plate by aforesaid breach, described first screw and second screw are in for not screwing under the state, and described briquetting breaks away from described second screw around described screw and described breach and rotates.

2, department's pin that is applied to mould according to claim 1 or pin changing device more, it is characterized in that described briquetting is that two ends have circular-arc bar blocks, described breach is opened in the first end of described briquetting, described screw then be located at aforementioned first end opposite second end on.
