[0014] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0015] The technical solution specifically implemented in this utility model is:

[0016] like Figure 1 and Figure 2As shown, a die-casting mold for processing automobile parts comprises a base plate 1, a fixed mold 2 is provided on the upper surface of the base plate 1, lifting cylinders 3 are provided on both sides of the upper surface of the base plate 1, a lifting connecting plate 4 is provided between the two lifting cylinders 3, a movable mold 5 is provided on the bottom surface of the lifting connecting plate 4, and the movable mold 5 is arranged corresponding to the fixed mold 2 in the upper and lower directions. An ejection device 6 for ejecting the die-casting in the fixed mold 2 is provided at the bottom of the fixed mold 2, and a linkage device 7 for driving the ejection device 6 to move up and down is provided between the ejection device 6 and the lifting connecting plate 4. The linkage device 7 comprises a pair of linkage rods 8, and the pair of linkage rods 8 are respectively arranged on both sides of the fixed mold 2, the upper end of the linkage rod 8 is fixedly connected to the lifting connecting plate 4, and the lower end of the linkage rod 8 passes through the ejection device 6 to connect the limiting block 9, and the length of the linkage rod 8 is equal to the difference between the maximum stroke distance of the lifting cylinder 3 and the up and down movement distance of the ejection device 6.

[0017] The base plate 1 is provided with avoidance holes 10 for the linkage rod 8 and the limit block 9 to pass through, and the number of the avoidance holes 10 is 2; when the movable mold 5 and the fixed mold 2 are pressed together, the avoidance holes 10 can prevent the linkage rod 8 and the base plate 1 from colliding with each other, thereby hindering the normal operation of the die-casting mold for processing automotive parts.

[0018] The ejection device 6 comprises an ejection block 11, an ejection rod 12 and a lifting push plate 13. The interior of the fixed mold 2 is provided with an empty slot 14 which passes through from left to right. The lifting push plate 13 is movably arranged in the empty slot 14. Both ends of the lifting push plate 13 extend to the exterior of the fixed mold 2 and are provided with mounting holes 15. The linkage rod 8 is passed through the mounting holes 15. The upper surface of the lifting push plate 13 is provided with the ejection rod 12. The ejection rod 12 passes through a card slot 16 to be connected to the ejection block 11. The card slot 16 is provided on the lower surface of the inner wall of the fixed mold 2.

[0019] The number of the ejector block 11, the ejector rod 12 and the card slot 16 is three, and the bottom ends of the three ejector rods 12 are fixedly connected to the lifting push plate 13;

[0020] Specifically, during the separation process of the movable mold 5 and the fixed mold 2, the linkage rod 8 can drive the lifting push plate 13 to move upward in the empty groove 14, so that the three ejector rods 12 on the lifting push plate 13 push up the three ejector blocks 11. Under the action of the three ejector blocks 11, the die-casting in the fixed mold 2 is automatically lifted up, which improves the work efficiency compared with the existing method of manually rotating and lifting the die-casting.

[0021] The above-mentioned linkage rod 8 and limit block 9 are L-shaped as a whole, and the cross-sectional width of the limit block 9 is larger than the aperture of the mounting hole 15; during the separation process of the movable mold 5 and the fixed mold 2, the linkage rod 8 can be pressed against the bottom surface of the lifting push plate 13 through the limit block 9, so that a pair of linkage rods 8 can drive the lifting push plate 13 to move upward.

[0022] After the die-casting of the automobile parts in the mold is completed, the lifting cylinder 3 drives the movable mold 5 to rise through the lifting connecting plate 4, and the lifting connecting plate 4 simultaneously drives a pair of linkage rods 8 to move upward. When the movable mold 5 is separated from the fixed mold 2 by a distance, the limit block 9 at the bottom end of the linkage rod 8 abuts against the bottom surface of the lifting push plate 13, and the linkage rod 8 continues to move upward. The linkage rod 8 drives the lifting push plate 13 to move upward in the empty groove 14, so that the three ejector rods 12 on the lifting push plate 13 push up the three ejector blocks 11. Under the action of the three ejector blocks 11, the die-casting in the fixed mold 2 is automatically lifted up, thereby facilitating people to take out the die-casting and improving work efficiency.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
