The method comprises the steps of S1, namely, a die casting die is formed by a movable die 2 and a fixed die 3, wherein in the use process of the die casting die, a die cavity is required to be designed according to product requirements, metal suitable for die casting, such as aluminum alloy, zinc alloy and the like, is selected, cooling grooves distributed in a serpentine shape are formed in the movable die 2 and the fixed die 3, cooling water is communicated, the movable die 2 and the fixed die are connected through a hose, a material injection pipeline is communicated with the movable die 2, a bendable movable pipeline is selected, the movable die 2 is required to move, molten metal is injected into the die through a nozzle of the material injection pipeline, high pressure is applied to fill the whole die cavity, after injection is completed, the cooling water is injected into the cooling grooves, rapid cooling is performed on the metal, the metal is solidified and molded, a die casting structural part is taken out after the die is completely solidified, and a die casting closed box is opened, and in the process of die casting, a hydraulic cylinder 4 is used as power, and a hydraulic rod 5 is driven to move the movable die 2, and after the die casting structural part is demoulded, the subsequent steps such as deburring, trimming and surface treatment are required to be performed;
S2, in the process of butting the movable die 2 and the fixed die 3, driving the side plate 20 to move, driving the toothed plate 21 to move by the side plate 20, pushing the toothed plate 6 by the rack 22 through the transmission of the rotating shaft 15, driving the fixed die 3 to turn over, enabling the die cavity of the fixed die 3 to be opposite to the die cavity of the movable die 2 when the rack 22 completely passes through the gear 6, limiting the gear 6 through the rack 22, avoiding the rotation of the gear 6, enabling the torsion spring 26 to be twisted and extruded in the process, enabling the spring 23 to be stressed and contracted when the movable die 2 continuously moves when the fixed die 3 is continuously in the box, keeping the toothed plate 21 relatively stable, and guaranteeing the effective butting of the movable die 2 and the movable die 2;
And S3, when the die casting die is opened, the movable die 2 is far away from the die casting fixed die 3, firstly, after the spring 23 loses extrusion force, the spring is elastically reset, after the spring 23 is completely reset, the pulling force drives the toothed plate 21 to move, the rack 22 at the lower end of the toothed plate 21 reversely pushes the gear 6, the fixed die 3 is driven to overturn through the linkage rotating shaft 15, meanwhile, the die cavity of the fixed die 3 is downwards supported through the torsion elastic support of the torsion spring 26, the automatic dumping and separation of a die casting is realized, the extra material taking action from the die casting die is avoided, a die casting structural member is supported through the guide plate 7 for transferring, the die transversely moves in the die opening process, and the output power of the hydraulic cylinder 4 is utilized.
The above-described embodiments are merely a few preferred embodiments of the present invention, and many alternative modifications and combinations of the above-described embodiments will be apparent to those skilled in the art based on the technical solutions of the present invention and the related teachings of the above-described embodiments.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
