[0016] Compared with the prior art, the present invention provides a demoulding device for aluminum alloy casting production, which has the following beneficial effects:

[0017] 1. The demolding device for aluminum alloy casting production places the aluminum alloy on the lower die base, then starts the hydraulic cylinder to move the lower die base downward, and at the same time starts the first motor to rotate the bidirectional screw. The rotation of the bidirectional screw will cause the two screw blocks to move toward each other, thereby causing the two first articulated frames to move toward each other. The first articulated frame will squeeze the articulated plate, so the opposite movement of the two first articulated frames will cause the two second articulated frames to move downward, thereby driving the first slide plate and the connecting block to move downward until the top of the connecting block coincides with the top of the lower die base. The first motor can then be stopped, and the aluminum alloy is cast. After casting is completed, the upper die base moves upward through the operation of the hydraulic cylinder. At this time, the first motor will also work, causing the bidirectional screw to rotate in the opposite direction, thereby driving the two screw blocks to move in opposite directions and toward each other, moving the first slide plate and the connecting block upward, and ejecting the aluminum alloy from the lower die base, thereby facilitating demolding the aluminum alloy.

[0018] 2. The demoulding device for aluminum alloy casting production starts the second motor after the aluminum alloy casting is completed to rotate the cross cylinder. The rotation of the cross cylinder causes the arc surface of the arc block to contact the lower die base, hitting the lower die base. The vibration force generated by the hitting is transmitted to the aluminum alloy, and the vibration force is used to separate the aluminum alloy from the lower die base, making it more convenient to remove the aluminum alloy.

[0027] The utility model provides the following technical solutions:

[0028] Example 1

[0029] See also Figure 1-3 The utility model provides a technical solution: a demoulding device for aluminum alloy casting production, comprising a base 1, a first fixing rod 2 is fixedly connected to the top of the base 1, a fixing seat 3 is fixedly connected to the top of the first fixing rod 2, a hydraulic cylinder 4 is fixedly connected to the top of the fixing seat 3, an upper die seat 5 is fixedly connected to the output end of the hydraulic cylinder 4, a second fixing rod 6 is fixedly connected to the top of the base 1, a lower die seat 7 is fixedly connected to the top of the second fixing rod 6, a demoulding mechanism 8 is provided on the top of the base 1, and a striking mechanism 9 is provided on the bottom of the base 1 near the front;

[0030] The demoulding mechanism 8 includes a moving component 81 and a lifting component 82. The moving component 81 is arranged on the top of the base 1, and the lifting component 82 is arranged on the top of the moving component 81.

[0031] The moving assembly 81 includes a connecting frame 811, which is fixedly connected to the top of the base 1 in a front-to-back symmetrical manner. A bidirectional screw 812 is rotatably connected to the right side of the connecting frame 811 near the surface of the top of the base 1. A first motor 813 is fixedly connected to the left side of the connecting frame 811 near the front of the top of the base 1. Screw blocks 814 are symmetrically threaded on the surface of the bidirectional screw 812. Limit rods 815 are fixedly connected to the left and right sides of the connecting frame 811 near the front of the bottom of the base 1.

[0032] The lifting assembly 82 includes a first articulated frame 821, the top of the first articulated frame 821 is fixedly connected to the top of the screw block 814, a hinged plate 822 is hinged inside the first articulated frame 821, and the other end of the articulated plate 822 is hinged to the second articulated frame 823, a slide groove 824 is opened in the lower mold base 7, a first slide plate 825 is connected to the slide groove 824 for sliding up and down, and a connecting block 826 is fixedly connected to the top of the first slide plate 825.

[0033] The output end of the first motor 813 is fixedly connected to the left end of the bidirectional screw 812. A hole matching the limiting rod 815 is opened on the left side of the screw block 814 near the front, and the screw block 814 is slidably connected to the surface of the limiting rod 815 through the hole, limiting the screw block 814 so that the screw block 814 can only move with the rotation of the bidirectional screw 812.

[0034] A groove matching the connecting block 826 is formed on the top of the lower die base 7 , and the surface of the connecting block 826 is slidably connected to the groove, and the top of the second hinge frame 823 is fixedly connected to the bottom of the first slide plate 825 .

[0035] Example 2

[0036] See also Figure 4 , and on the basis of embodiment 1, a striking mechanism 9 is further obtained.

[0037] The striking mechanism 9 includes a fixed sleeve 91, which is fixedly connected to the top of the base 1 near the front. A second motor 92 is fixedly connected inside the fixed sleeve 91, and a cross cylinder 93 is fixedly connected to the output end of the second motor 92. An arc block 94 is slidably connected inside the cross cylinder 93, and a second slide 95 is fixedly connected to the top of the arc block 94. A connecting plate 96 is fixedly connected to the top of the cross cylinder 93. A guide rod 97 is fixedly connected to the side of the connecting plate 96 close to the second slide 95, and a spring 98 is sleeved on the surface of the guide rod 97 between the connecting plate 96 and the second slide 95.

[0038] A groove matching the second slide plate 95 is formed on the top of the cross cylinder 93 , and the surface of the second slide plate 95 passes through and is slidably connected in the groove.

[0039] A hole matching the guide rod 97 is formed on one side of the second slide plate 95 close to the connecting plate 96 , and the guide rod 97 passes through the surface and is slidably connected in the hole.

[0040] One end of the spring 98 is fixedly connected to a side of the second slide plate 95 close to the connecting plate 96 , and the other end of the spring 98 is fixedly connected to a side of the connecting plate 96 close to the second slide plate 95 .

[0041] In actual operation, when this device is used, the aluminum alloy is placed on the lower die base 7, and then the hydraulic cylinder 4 is started to move the lower die base 7 downward. At the same time, the first motor 813 is started to rotate the bidirectional screw 812. The rotation of the bidirectional screw 812 causes the two screw blocks 814 to move toward each other, thereby causing the two first articulated frames 821 to move toward each other. The first articulated frames 821 will squeeze the articulated plate 822, so the movement of the two first articulated frames 821 toward each other will cause the two second articulated frames 823 to move downward, thereby driving the first slide plate. 825 and the connecting block 826 move downward until the top of the connecting block 826 coincides with the top of the lower die base 7, and the operation of the first motor 813 is stopped. Then, the aluminum alloy is cast. After the casting is completed, the upper die base 5 moves upward by the operation of the hydraulic cylinder 4. At this time, the first motor 813 also works to make the bidirectional screw 812 rotate in the opposite direction, thereby driving the two screw blocks 814 to move in opposite directions, so that the first slide 825 and the connecting block 826 move upward, and the aluminum alloy is ejected from the lower die base 7, which is convenient for demolding the aluminum alloy.

[0042] After the aluminum alloy casting is completed, the second motor 92 is started to rotate the cross cylinder 93. The rotation of the cross cylinder 93 will cause the arc surface of the arc block 94 to contact the lower die base 7, hitting the lower die base 7. The vibration force generated by the hitting is transmitted to the aluminum alloy, and the vibration force is used to separate the aluminum alloy from the lower die base 7, making it more convenient to take out the aluminum alloy.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
