[0027] like Figure 1-2 As shown, this example can achieve the effect of reinforcing the cover body 501.

[0028] Since the high-strength die-cast aluminum alloy includes a cover body 501, vertical edges 502 and L-shaped edges 505, the outer side of the cover body 501 is annularly integrally formed with multiple L-shaped edges 505, and the inner side of the cover body 501 is annularly integrally formed with multiple vertical edges 502, each vertical edge 502 is located between two adjacent L-shaped edges 505, the outer side of the cover body 501 is reinforced by the multiple L-shaped edges 505, and the inner side of the cover body 501 is reinforced by the multiple vertical edges 502, and the vertical edges 502 and the L-shaped edges 505 are staggered to further reinforce the cover body 501.

[0029] like Figure 1-2 As shown, this example can achieve the effect of fixing the cover body 501 at a desired position through the screws on the screw holes 504.

[0030] Since the high-strength die-cast aluminum alloy also includes an annular edge 503 and a screw hole 504, the annular edge 503 is arranged on the outer side of the cover body 501, and two screw holes 504 are relatively arranged on the annular edge 503. The cover body 501 is used as a cover. The cover body 501 can be covered at a desired position through the annular edge 503, and screws can be inserted into the two screw holes 504, and then the cover body 501 is fixed at a desired position through the screws on the screw holes 504.

[0031] like Figure 6-8 As shown, this example can achieve the effect of forming multiple L-shaped ribs 505 through multiple L-shaped grooves 102.

[0032] Since the high-strength die-cast aluminum alloy is manufactured by a die-casting device, the die-casting device includes a lower mold 101, an L-shaped groove 102, a thin circular space 103 and a thick circular space 107. The inner lower end of the lower mold 101 is provided with a thin circular space 103, the inner upper end of the lower mold 101 is provided with a thick circular space 107, and a plurality of L-shaped grooves 102 are annularly arranged on the thin circular space 103. The aluminum alloy is poured into the lower mold 101, the thin circular space 103 is used to form the cover 501 part, the thick circular space 107 is used to form the annular edge 503 part, and a plurality of L-shaped edges 505 are formed by a plurality of L-shaped grooves 102.

[0033] like Figure 6-8 As shown in Figures 12-13, this example can facilitate the removal of the aluminum alloy part from the lower mold 101.

[0034] Since the die-casting device also includes an annular groove 109 and an annular cylinder 401, the annular groove 109 is arranged at the lower end of the thin circular space 103, and the upper side of the annular groove 109 is in the same plane as the upper sides of the multiple L-shaped grooves 102. The annular cylinder 401 is inserted into the annular groove 109 from the lower side. When the annular cylinder 401 is inserted into the annular groove 109, the annular groove 109 can be closed. When the die-casting of the aluminum alloy part is completed, the annular cylinder 401 can be pulled off the annular groove 109, and then the solidified aluminum alloy part can be poked through the annular cylinder 401, so that the aluminum alloy part can be taken out from the lower mold 101.

[0035] like Figure 12-13 As shown, this example can achieve the effect of preventing the L-shaped rib 505 from being stuck in the L-shaped groove 102.

[0036] Since the die-casting device also includes a protrusion 404, a plurality of protrusions 404 are arranged in a ring shape on the ring cylinder 401, and the plurality of protrusions 404 can be inserted into the plurality of L-shaped grooves 102 through the annular groove 109. When the solidified aluminum alloy part needs to be taken out from the lower mold 101, the ring cylinder 401 is turned over and inserted into the annular groove 109, so that the plurality of protrusions 404 are inserted into the annular groove 109, and the plurality of protrusions 404 are respectively inserted into the plurality of L-shaped grooves 102, thereby facilitating the poking out of the L-shaped ridges 505 formed by the plurality of L-shaped grooves 102, and preventing the L-shaped ridges 505 from being stuck in the L-shaped grooves 102.

[0037] like Figure 6-8 As shown, this example can achieve the effect of facilitating the alignment of the annular cylinder 401 with the annular groove 109 .

[0038] Since the die-casting device also includes a conical ring 110, the conical ring 110 is arranged on the lower side of the lower mold 101, and the conical ring 110 is located on the outside of the annular groove 109. The conical surface on the inner side of the conical ring 110 can facilitate the insertion of the annular groove 109 and the alignment of the annular groove 109.

[0039] like Figure 9-11 As shown, this example can achieve the effect of forming a cover body 501 and an annular edge 503 .

[0040] Since the die-casting device also includes a top cover 301 and a convex cylinder 304, the convex cylinder 304 is integrally formed on the lower side of the top cover 301, the convex cylinder 304 can be inserted into the fine circular space 103, and the top cover 301 can cover the upper side of the lower mold 101. When the convex cylinder 304 is inserted into the fine circular space 103, a cover body 501 is formed between the convex cylinder 304 and the lower mold 101. When the top cover 301 covers the upper side of the lower mold 101, an annular edge 503 is formed between the top cover 301 and the lower mold 101.

[0041] like Figure 6-8As shown, this example can achieve the effect of controlling the convex cylinder 304 to move closer to and away from the lower mold 101.

[0042] Since the die-casting device also includes a hydraulic cylinder 1104, a lifting seat 105, a guide rod 106 and a bracket 108, the lower mold 101 is connected to the bracket 108 by screws, and guide rods 106 are welded to the left and right ends of the bracket 108. Each guide rod 106 is slidably connected to a lifting seat 105, and the lifting seat 105 is driven to slide by the hydraulic cylinder 1104. The top cover 301 is connected between the two lifting seats 105 by screws. When the two hydraulic cylinders 1104 are extended and retracted at the same time, the two lifting seats 105 are driven to slide on the two guide rods 106 respectively, thereby controlling the lifting and lowering of the top cover 301 and the convex cylinder 304, and then controlling the convex cylinder 304 to approach and move away from the lower mold 101.

[0044] Since the die-casting device also includes a middle hole 303, a piston 306, a pipe 308 and a blocking member 310, the middle hole 303 is arranged at the center of the top cover 301 and the convex cylinder 304, the piston 306 is slidably connected to the middle hole 303, a compression spring is arranged between the top cover 301 and the upper part of the piston 306, a blocking member 310 is welded on the top cover 301, the blocking member 310 blocks the upper end of the piston 306, the pipe 308 is arranged on the piston 306, the pipe 308 runs through the piston 306, and aluminum alloy water can be injected into the lower mold 101 through the pipe 308. The compression spring usually gives an upward force to the piston 306, so that the piston 306 contacts the blocking member 310. After the aluminum alloy water is injected into the lower mold 101, the piston 306 is pressed downward to move the piston 306 downward, so that the pressure in the lower mold 101 increases, so that the aluminum alloy water fills the lower mold 101, and avoids incomplete aluminum alloy parts produced by die-casting.

[0045] like Figure 9-11 As shown, this example can achieve the effect of forming vertical ribs 502 and screw holes 504 on the aluminum alloy part.

[0046] Since the die-casting device further includes a convex column 302 and a vertical groove 305, the left and right ends of the lower side of the top cover 301 are provided with a convex column 302, and the outer periphery of the convex cylinder 304 is provided with a plurality of vertical grooves 305 in an annular shape. The convex column 302 can form two screw holes 504 on the annular edge 503, and the plurality of vertical grooves 305 are used to form the vertical ridge 502.

The hydraulic cylinder III309 is connected to the top cover 301 by screws, and the lower end of the hydraulic cylinder III309 presses on the pressure fork 307.

[0048] like Figure 9-11 As shown, this example can achieve the effect of driving the piston 306 to move downward.

[0049] When the hydraulic cylinder III309 is extended, it can drive the pressure fork 307 to rotate and press downward, so that the pressure fork 307 presses on the piston 306 to drive the piston 306 to move downward, thereby driving the pressure in the lower mold 101 to increase.

[0050] The die-casting device also includes a gantry 201, a U-shaped seat 202, a hydraulic cylinder II203, a slide 402, a side shaft 403 and a motor 405. The two slides 402 are respectively connected to the two ends of the bracket 108 in a vertical sliding manner. Side shafts 403 are welded on both sides of the ring cylinder 401. The outer ends of the two side shafts 403 are respectively connected to the two slides 402 through bearings. One of the side shafts 403 is driven by the motor 405. U-shaped seats 202 are provided at both ends of the gantry 201. The two U-shaped seats 202 are respectively placed on the lower sides of the two side shafts 403. The gantry 201 is connected to the hydraulic cylinder II203 by screws, and the movable end of the hydraulic cylinder II203 is connected to the lower part of the bracket 108 by screws.

[0051] like Figure 6-13 As shown, this example can achieve the effect of driving the ring cylinder 401 to flip and rise and fall.

[0052] When the hydraulic cylinder II203 is extended or retracted, it can drive the gantry 201 and the two U-shaped seats 202 to rise and fall. The rising and falling of the two U-shaped seats 202 can drive the two side shafts 403 to rise and fall, thereby driving the two slide seats 402 to slide vertically on the bracket 108, thereby driving the annular cylinder 401 to insert into or leave the annular groove 109, and the motor 405 can drive the annular cylinder 401 to rotate around the two side shafts 403, thereby driving the annular cylinder 401 to flip.
