Description

Mold rapid-replacement device

The utility model relates to a kind of die-changing apparatus, especially for the die-changing apparatus of punching press, extruding lathe.

The progress of mechanical industry is the one of the main reasons that drives modern civilization, a large amount of use machinery on productivity ratio and product quality manual operations be greatly improved, so high efficiency and automation are the emphasis that modern mechanical designs.

In existing extruding, the pressing equipment; when desiring more mold exchange; must shut down; change another mould by the workman by using certain instrument again; after the mould installation; restart machine again, this method more mold exchange needs long downtime and causes minimizing output, and artificial die change also will increase the danger of workman's operation.

Die change structural representation such as Fig. 4 of prior art, form by main frame slide 3, die holder 4, die change pad 5 and die holder cylinder 6, die holder 4 on the main frame slide 3 and die change pad 5 can be driven by die holder cylinder 6 and move, side at die holder 4, one embedded hole 41 is arranged, can embed the chimeric block 51 of die change pad 5 in this embedded hole 41.The top of die holder 4 is mounted with die holder 42, and the center of die change pad 5 is a perforation 52.When die change pad 5 moves to the position of die holder 4, can be with the extruding defective material by releasing in the perforation 52.Side at die change pad 5 has die holder cylinder 6,7, when desire is removed defective material, die holder cylinder 6 promptly promotes die change pad 5 to nib 52 positions, and when die change, die holder cylinder 6 is released die holder 4 again, make the workman die holder 42 can be taken out and change another mould and place on the die holder 4, by die holder cylinder 7 die holder is returned to the position of nib 42 again.

The sheerly manually-operated of the mode of operation of above-mentioned existing use, die change is long downtime, carries not at that time when the dress mould, will increase the danger of operation.

The purpose of this utility model is: establish a mold rapid-replacement device in original equipment die change seat one side, make the mould of usefulness with place a side treat the mold exchange fast changeable, to reduce the waste of downtime, the efficient and the security that can improve equipment.

The utility model is achieved in that the opposite side at the main frame slide is provided with die change seat and preparation die holder, and the die change seat is vertical with main frame and be made up of die change base, slide and die change cylinder, and the die change base is located at the bottom of die change seat and is provided with chute; Slide places on the die change base, and its bottom is provided with protruding rail, and slide can be by protruding rail slippage on chute; The front end of slide also is provided with a projection, this projection and the axostylus axostyle winding of being located at the die change cylinder of die change base, making the die change cylinder can drive slide moves, in addition, be provided with groove on slide, this groove can be set die holder, and the preparation die holder places on the die change seat, the one side is provided with the embedded hole corresponding with projection, and the die holder on the main frame slide can be passed to the die change seat and carry out die change fast thus.

The utility model compared with the prior art, its advantage is:

1, can reduce mould replacing time significantly, increase productivity ratio;

2, operating personnel do not need directly to change with hand the mould of high temperature, and it is safe.

Description of drawings:

Fig. 1 is the utility model assembling front view;

Fig. 2 is the utility model assembling side elevation;

Fig. 3 is the utility model action schematic diagram;

Fig. 4 changes the die holder schematic diagram for prior art;

Accompanying drawing is described in conjunction with the embodiments:

The utility model mainly comprises die change seat 1 and preparation die holder 2 (Fig. 1,2), wherein:

Die change seat 1 is located at one of main frame slide 3 side and vertical with main frame slide 3, is made up of die change base 11, slide 12, die change cylinder 13, and die change base 11 is located at the bottom of die change seat, and chute 111 is arranged; Slide 12 is located on the die change base 11, and protruding rail 121 is arranged at the bottom of slide 12, makes the slide 12 can be by protruding rail 121 slippage on chute 111; Slide 12 front ends are provided with a projection 122, and the axostylus axostyle winding of this projection 122 and die change cylinder 13 also is provided with groove 123 on slide 12, make this groove 123 can rabbet die holder 2; Die change cylinder 13 is located at the bottom of die change seat 1, and its axostylus axostyle nationality projection 122 drives slide 12 and moves; In addition, preparation die holder 2 places on the die change seat 1, and the one side has an embedded hole 21, and this embedded hole 21 can be set the chimeric block 51 of die change pad 5.

When the utility model carries out die change when action, as shown in Figure 3, treat that mold exchange gives for one group and place earlier on the preparation die holder 2 that the die holder 4 of main frame slide 3 can be passed by die holder cylinder 6, on slide 12 grooves 123 that die holder 4 are pushed move to die change seat 1; Start die change cylinder 13 this moment, then slide 12 is promptly driven reach, and at this moment, the embedded hole 41 of die holder 4 promptly separates with chimeric block 51, and the embedded hole 21 of preparation die holder 2 is then chimeric with chimeric block 51 because of reach; To prepare die holder 2 by die holder cylinder 7 again and be returned on the main frame slide 3, promptly finish the die change program apace.
