[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-Figure 5 , a mold for precision casting of aviation castings, comprising:

[0030] Upper mold 1 and lower mold 2;

[0031] The first die 101 is fixedly connected to the upper die 1;

[0032] The second pressing die 201 is fixedly connected to the lower die 2;

[0033] The first die 101 is located directly above the second die 201;

[0034] A driving cylinder 3 is fixedly connected to both the upper mold 1 and the lower mold 2;

[0035] The oil delivery pipe 6 is fixedly connected to the driving cylinder 3 .

[0036] A push rod 8 is fixedly connected to both the upper mold 1 and the lower mold 2 , a sliding plug 302 is slidably connected in the driving cylinder 3 , a sliding rod 7 is fixedly connected to the sliding plug 302 , and the sliding rod 7 is connected to the push rod 8 .

[0037] The push rod 8 is fixedly connected with a first magnet 801 , and the slide rod 7 is fixedly connected with a second magnet 701 . The first magnet 801 and the second magnet 701 attract each other.

[0038] Reference Figure 1-Figure 5 During use, the workpiece to be stamped is placed on the second die 201 of the lower die 2. After placement, the first die 101 is driven downward by the upper die 1. After the upper die 1 slides for a distance, the first die 101 and the workpiece are against each other. At this time, the upper die 1 continues to move downward. At this time, under the mutual extrusion of the first die 101 and the second die 201, the workpiece can be stamped into shape.

[0039] During the downward movement of the upper mold 1, the push rod 8 on the upper mold 1 will move downward synchronously. At this time, after the push rod 8 moves downward for a distance, the push rod 8 will collide with the slide bar 7. At this time, the first magnet 801 and the second magnet 701 attract each other. At this time, when the upper mold 1 continues to move downward, the slide bar 7 will move downward synchronously. The downwardly moved slide bar 7 will synchronously push the slide plug 302 to move downward. The downwardly moved slide plug 302 will squeeze out the lubricating oil in the driving cylinder 3. The extruded lubricating oil will be transported through the oil pipe 6. The transported lubricating oil will be sprayed on the second die 201. The lubricating oil sprayed on the second die 201 will flow and immerse into the workpiece surface, thereby facilitating the subsequent demolding of the workpiece.

[0040] Reference Figure 3When the upper mold 1 moves downward, the push rod 8 on the lower mold 2 will push the slide plug 302 to move, thereby squeezing the lubricating oil in the driving cylinder 3 into the first die 101, and the delivered lubricating oil will be sprayed on the second die 201. The lubricating oil sprayed on the second die 201 will flow and immerse into the surface of the workpiece, thereby facilitating the subsequent demolding of the workpiece.

[0041] The upper die 1 in the device moves downward, thereby squeezing the lubricating oil onto the first die 101 and the second die 201, and then can penetrate between the workpiece and the first die 101 and the second die 201, thereby facilitating the subsequent demoulding of the workpiece.

[0042] An oil inlet pipe 4 is fixedly connected to the side wall of the driving cylinder 3 .

[0043] Both the oil inlet pipe 4 and the oil delivery pipe 6 are provided with a one-way valve 5 .

[0044] The sliding plug 302 is fixedly connected with a spring 301 , and one end of the spring 301 away from the sliding plug 302 is fixedly connected to the inner wall of the driving cylinder 3 .

[0045] Reference Figure 4 The spring 301 is provided to enable the sliding plug 302 to be quickly reset. When the sliding plug 302 is reset, the driving cylinder 3 can draw external lubricating oil through the oil inlet pipe 4, so as to facilitate the next use.

[0046] The slide bar 7 is fixedly connected with a limit plate 702 , and the limit plate 702 and the driving cylinder 3 are against each other.

[0047] Reference Figure 4 By setting the limiting plate 702, when the push rod 8 pushes the slide rod 7 to slide down, it can prevent the slide rod 7 from excessively sliding and completely entering the driving cylinder 3.

[0048] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
