[0036] Please refer to Figures 1-11 ​​The aviation aluminum alloy die casting die provided by the embodiment of the present application comprises a first base 1 and a second base 2 arranged oppositely and a top plate 3 arranged on the first base 1 and the second base 2, a fixed die seat 4 and a movable die seat 5 are arranged on the first base 1 and the second base 2 respectively, and a half die 6 is arranged on the fixed die seat 4 and the movable die seat 5 respectively, further comprising: a box body 7 arranged on the downside of the top plate 3 in a lifting manner; a shunt pipe 8 hinged to the side wall of the box body 7, a plurality of nozzles 9 are arranged on the shunt pipe 8; a linkage assembly for driving the shunt pipe 8 to swing the nozzles 9 up and down reciprocatingly when the box body 7 is lifted; and a driving assembly for driving the box body 7 to perform lifting movement when the fixed die seat 4 and the movable die seat 5 are separated.

[0037] Specifically, the first base 1 and the second base 2 are arranged at intervals; the top plate 3 is horizontally fixed on the top of the first base 1 and the second base 2; the fixed die seat 4 is fixedly connected to the side wall of the first base 1 facing the second base 2, the movable die seat 5 is movably connected to the side wall of the second base 2 facing the first base 1, and the moving direction is opposite to the fixed die seat 4 to approach or move away, the two half dies 6 arranged on the fixed die seat 4 and the movable die seat 5 are the die casting die of the same group of aluminum alloy products, and are arranged in correspondence when being installed. The box body 7 is provided with the shunt pipe 8 on both sides, the nozzles 9 on the shunt pipe 8 are directed to the direction of the half die 6, and the angle of the shunt pipe 8 swinging the nozzles 9 up is preferably 30°-60°; the axis of the shunt pipe 8 is the rotating shaft thereof; the shunt pipe 8 is arranged transversely, and the plurality of nozzles 9 are arranged transversely and uniformly on the shunt pipe 8, which can cover the corresponding transverse dimension of the half die 6; the lifting of the box body 7 and the rotation of the shunt pipe 8 are linked by the linkage assembly, so that the shunt pipe 8 swings the nozzles 9 up and down reciprocatingly when the box body 7 is lifted. In actual use, after the movable die seat 5 moves away from the fixed die seat 4, the driving assembly drives the box body 7 to descend and then ascend, in this process, the shunt pipe 8 supplies the nozzles 9 with the release agent and sprays it out, at the same time, the shunt pipe 8 rotates reciprocatingly under the linkage assembly to swing the nozzles 9 up and down reciprocatingly, forming a plurality of angle spraying directions, and spraying the release agent on the cavity wall of the half die 6, eliminating the release agent leakage phenomenon and realizing overall spraying.

[0038] Compared with the prior art, the aviation aluminum alloy die casting die provided by the embodiment of the present application can supply the nozzles 9 with the release agent and spray it out by the shunt pipe 8 when the driving assembly drives the box body 7 to lift between the separated fixed die seat 4 and movable die seat 5, at the same time, the shunt pipe 8 swings the nozzles 9 up and down reciprocatingly to form a plurality of angle spraying directions to spray the release agent on the cavity wall of the half die 6, eliminating the release agent leakage phenomenon and realizing overall spraying, thereby improving the practicability of the device.

[0040] As a further preferred technical scheme of the embodiment, the reciprocating assembly comprises a take-up reel 14 elastically rotating in the box body 7, one end of a pull wire 15 connected and released from the take-up reel 14 penetrates the box body 7 to be connected to the top plate 3, an eccentric rod 16 is fixedly arranged on one end surface of the take-up reel 14, and the linkage frame 10 is provided with a linkage groove 17 matched with the eccentric rod 16; specifically, a coil spring connected with the rotating shaft of the take-up reel 14 is arranged in the box body 7, so that the take-up reel 14 maintains the tendency of winding the pull wire 15 under the influence of the elastic force; the axial direction of the take-up reel 14 is parallel to the axial direction of the rotating shaft of the shunt pipe 8; the direction in which the pull wire 15 is connected to the top plate 3 is preferably vertical, and the winding length of the pull wire 15 meets the lifting needs of the box body 7; the eccentric rod 16 performs circular motion with the take-up reel 14, and then drives the linkage frame 10 to reciprocate lift through the linkage groove 17, and the eccentric rod 16 itself moves horizontally in the linkage groove 17. In actual use, in the process of lowering the box body 7, the pull wire 15 is slowly pulled out from the take-up reel 14, the take-up reel 14 rotates against the elastic force, and then drives the linkage frame 10 to reciprocate lift through the eccentric rod 16 and the linkage groove 17, and in the process of lifting the box body 7, the take-up reel 14 rotates back under the elastic force, so that the pull wire 15 is automatically wound, and the rotation of the take-up reel 14 also drives the linkage frame 10 to reciprocate lift through the eccentric rod 16 and the linkage groove 17.

The driving assembly can be reversely driven. In one direction of the driving assembly, the movable die seat 5 is first driven to move away from the fixed die seat 4, and then the box body 7 is driven to descend from the highest position when the movable die seat 5 moves to the farthest position away from the fixed die seat 4. When the box body 7 descends to the lowest position, the driving assembly changes the driving direction, and then the box body 7 is first driven to ascend from the lowest position to the highest position, and then the movable die seat 5 is driven to move close to the fixed die seat 4 to close the die. As a result, there is no interference of arbitrary movement, and the need for spraying the release agent is met.

During the lowering of the box body 7, the second interface 32 is kept open, and during the lifting of the box body 7, the second interface 32 is kept closed.

In actual use, when the transmission gear 22 rotates in the direction of lowering the screw rod 18, the transmission gear 22 pushes the pawl 35 in this direction, the pawl 35 first drives the sliding piece 34 to move synchronously, the sliding piece 34 drives the plunger 33 to move away from the conduit 36 to make the second interface 32 not be blocked, then the sliding piece 34 cannot continue to move, the transmission gear 22 drives the pawl 35 to move relative to the sliding piece 34, the pawl 35 moves against the elastic force and rebounds after each tooth top of the transmission gear 22 passes, thereby keeping the above position of the sliding piece 34, and the release agent can be smoothly guided out.
