Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments, it is to be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to fig. 1-3, the utility model provides a quick installation auxiliary device of drawing die ejector pin 11, including mould body 1, ejector pin 11 and locating plate 2, the most common mode of cold working is exactly the punching press, and the back is accomplished in the punching press of mould body 1, unloads through ejector pin 11. Therefore, the position of the jack 11 is strictly defined. The ejector rod 11 is connected with the die body 1 through an ejector rod hole 12 on the die body 1; the die body 1 is provided with a plurality of ejector rod holes 12 for being inserted and matched with the ejector rods 11, the positioning plate 2 is provided with a plurality of positioning holes 21, and the plurality of positioning holes 21 and the plurality of ejector rod holes 12 are vertically arranged in a one-to-one correspondence manner; 2 length and width of locating plate all are less than mould body 1, and both ends all are equipped with recess 211 about locating hole 21, and the recess 211 diameter is greater than 11 diameters of ejector pin. Since the positions of the pin holes 12 are generally fixed and the diameters of the adjacent pins 11 are substantially the same, they can be easily distinguished by the naked eye. The positioning holes 21 on the positioning plate 2 correspond to the ejector rod holes 12 in the vertical direction one by one; utilize locating plate 2 to carry out the calibration location to the locating position fast this moment, designed in advance on the locating plate 2 with the corresponding locating hole 21 in technology card position, place locating plate 2 on mould body 1, according to the light transmissivity, can judge the position that ejector pin 11 should place, then place in ejector pin hole 12 can.

Preferably, the utility model discloses a be equipped with a plurality of keyway 13 on the mould body 1, be equipped with two central grooves 22 that are parallel to each other on the locating plate 2. In the mould body 1, there is strict limit to the position of locating hole 21, and the keyway 13 precision is high, fixes a position the back through keyway 13, and the position of every ejector pin hole 12 is more convenient for place or get rid of, utilizes two central grooves 22 that are parallel to each other, can conveniently realize the support and the slip of locating plate 2, then through keyway 13 and the central groove 22 that is located on locating plate 2, is favorable to finding the central point of mould body 1 fast and puts.

In addition, the utility model discloses a have the location bracing piece 23 that matches with keyway 13 through wheel components sliding connection in the central groove 22. Under the effect of wheel components and location bracing piece 23, be convenient for remove locating plate 2 to the assigned position.

Further, the utility model discloses an it has apron 24 all to articulate on every locating hole 21. The positions of the ejector rods 11 on each process card are different, the positioning plates 2 which are frequently used can be directly processed to form the required positioning holes 21, and for the process cards with lower use frequency, the positions of the positioning holes 21 are adjusted through the cover plate 24, and then the process cards are placed on the die body 1, so that the positioning plates 2 can be reused.

Preferably, the cover plate 24 of the present invention is rotatably connected to the upper side of the positioning hole 21 by the pin. The cover plate 24 can be embedded in the positioning hole 21 except the upper side of the positioning hole 21, the installation is more convenient when the cover plate is positioned on the outer side, and the mutual interference of the cover plate 24 can be reduced when the cover plate is positioned on the inner side. In order to facilitate the rotation of the cover plates 24, each cover plate 24 needs to be provided with a poke rod (not shown in the figure), the poke rod should be arranged on the end surface of the cover plate 24, and in the operation process, the poke rod can be used for directly driving the cover plate 24 to rotate, so that the operation is more labor-saving. In practical use, the cover plate 24 should be shaped like a spindle with a smaller end and a larger end, so as to reduce the occupied space of the cover plate 24.

In order to achieve better technical effect, the utility model discloses a be equipped with spacing boss 14 on the locating hole 21. The limiting boss 14 can be a hemispherical protrusion, in the using process, according to a process card, the limiting hole 21 which does not participate in the work needs to be covered, and the cover plate 24 can be clamped by the limiting boss 14 in the rotating process to realize the fixation.
