Abstract
Description
Technical Field
[0001] This application relates to the field of raw material processing technology, and in particular to a flipping demolding device. Background Technology
[0002] Through years of technological advancements, the production of conventional aluminum ingots has become automated. However, with the expansion of production scale and the improvement of efficiency, and considering factors such as production, packaging, transportation, and costs, domestic manufacturers have begun to demand customized aluminum ingots weighing over 500 kg. For these large aluminum ingots weighing over 500 kg, embedded lifting lugs are typically used during demolding. Compared to traditional iron lifting lugs, using aluminum embedded lugs avoids the problems of lug deformation and oxidation contaminating the aluminum ingot.
[0003] Aluminum lifting lugs are generally made by one-piece casting. During the casting and demolding process, the mold needs to be rotated 180° repeatedly. However, due to the heavy weight of the aluminum lifting lug and the mold, there is a risk of finger pinching during operation. Utility Model Content
[0004] Therefore, it is necessary to provide a highly safe flipping and demolding device to address the aforementioned technical problems.
[0005] An embodiment of the first aspect of this application provides a flipping demolding device, including a base, a support mechanism, a limiting mechanism, and a mold. The support mechanism is connected to the base. The limiting mechanism and the support mechanism are located on the same side of the base in the height direction. The limiting mechanism includes a first connecting member and a first protrusion connected to each other. The first connecting member is connected to the base, and the first protrusion is located on the side of the first connecting member away from the base. A mold groove is provided on one side of the mold. The mold is rotatably connected to the base via a rotating shaft, so that the mold has a casting state and a demolding state that can be switched. In the casting state, the opening of the mold groove is located on the side of the mold away from the base, and the mold abuts against the support mechanism. In the demolding state, the opening of the mold groove faces the base, and the mold abuts against the first protrusion. A gap is formed between the mold and the first connecting member.
[0006] In one embodiment, the support mechanism and the limiting mechanism are located on both sides of the rotating shaft in a first direction, which intersects the height direction.
[0007] In one embodiment, the limiting mechanism includes a plurality of first protrusions, which are spaced apart along a second direction, and the first direction, the second direction and the height direction are arranged to intersect each other.
[0008] In one embodiment, the support mechanism includes a second connector and a second protrusion that are interconnected, the second connector being connected to the base and the second protrusion being located on the side of the second connector facing away from the base.
[0009] In one embodiment, the pivot, the first connector, and the second connector all extend along a second direction, which intersects the height direction.
[0010] In one embodiment, it further includes: a bearing housing, which is sleeved on the rotating shaft so that the rotating shaft can rotate relative to the bearing housing, one of the bearing housing and the rotating shaft being connected to the base and the other being connected to the mold.
[0011] In one embodiment, the cross-sectional area of the mold groove gradually decreases along the direction away from the opening of the mold groove.
[0012] In one embodiment, the base has multiple rollers on the side facing away from the mold.
[0013] In one embodiment, it also includes a handle that is connected to the mold.
[0014] In one embodiment, the first bump has a dimension of 20 mm in the height direction.
[0015] The flipping and demolding device provided in this application allows the mold to be rotatably connected to the base via a rotating shaft, enabling the mold to switch between a casting state and a demolding state. In the casting state, molten aluminum is poured in; after the aluminum cools and solidifies, the mold is rotated to switch to the demolding state, causing the mold groove opening to face downwards, allowing the aluminum lifting lugs to separate from the mold and complete demolding. This method is simple to operate and allows for repeated casting of multiple aluminum lifting lugs, improving production efficiency. By incorporating a support mechanism and a limiting mechanism, the mold is supported by the support mechanism and the limiting mechanism respectively in the casting and demolding states, improving the stability of the mold in both states. Simultaneously, it ensures that the maximum flipping angle remains consistent during repeated flipping, reducing the difficulty of manual operation and thus improving production efficiency. By including a first connecting member and a first protrusion in the limiting mechanism, and ensuring that the mold abuts against the first protrusion in the demolding state, a gap is formed between the mold and the first connecting member, reducing the contact area between the mold and the limiting mechanism and lowering the risk of finger pinching when the mold is in the demolding state, thereby improving the safety of the flipping and demolding device.

[0036] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the flipping and demolding device in the casting state according to some embodiments of this application. Figure 2 A schematic diagram of an example flipping demolding device in the demolding state is shown.
[0037] like Figure 1 and Figure 2 As shown, this application provides a flipping and demolding device 10, including a base 100, a support mechanism 200, a limiting mechanism 300, and a mold 400. The support mechanism 200 is connected to the base 100. The limiting mechanism 300 and the support mechanism 200 are located on the same side of the base 100 in the height direction (z direction in the figure). The limiting mechanism 300 includes a first connecting member 310 and a first protrusion 320 connected to each other. The first connecting member 310 is connected to the base 100, and the first protrusion 320 is located on the side of the first connecting member 310 away from the base 100. A mold groove 410 is provided on one side of the mold 400. The mold 400 is rotatably connected to the base 100 through a rotating shaft 500, so that the mold 400 has a casting state and a demolding state that can be switched. In the casting state, the opening of the mold groove 410 is located on the side of the mold 400 away from the base 100, and the mold 400 abuts against the support mechanism 200. In the demolded state, the opening of the mold groove 410 faces the base 100, and the mold 400 abuts against the first protrusion 320, forming a gap between the mold 400 and the first connecting member 310.
[0038] It is easy to understand that when the flipping demolding device 10 is placed on a horizontal surface, the mold 400 is located above the base 100. The mold 400 has a first surface 420 and a second surface 430 arranged opposite each other, and the opening of the mold groove 410 is located on the first surface 420. When the mold 400 is in the casting state, the second surface 430 faces downward, the first surface 420 faces upward, and the opening of the mold groove 410 also faces upward, which facilitates the pouring of molten aluminum into the mold groove 410. When the mold 400 is in the demolding state, the second surface 430 faces upward, the first surface 420 faces downward, and the opening of the mold groove 410 also faces downward, which facilitates the demolding of the formed aluminum lifting lug under the action of gravity.
[0039] Optionally, the support mechanism 200 and the limiting mechanism 300 are used to jointly limit the flipping angle of the mold 400. When the flipping demolding device 10 is placed on a horizontal surface, and the mold 400 is in both the casting and demolding states, the first surface 420 is flush with the horizontal surface. That is, the mold 400 rotates 180° when switching from the casting state to the demolding state, and rotates 180° in the opposite direction when switching from the demolding state to the casting state.
[0040] The flipping and demolding device 10 of this application embodiment allows the mold 400 to be rotatably connected to the base 100 via a rotating shaft 500, enabling the mold 400 to switch between a casting state and a demolding state. In the casting state, molten aluminum is poured in. After the molten aluminum cools and solidifies, the mold 400 is rotated to switch to the demolding state, causing the opening of the mold groove 410 to face downwards, allowing the aluminum lifting lugs to separate from the mold 400 and complete the demolding process. This method is simple to operate and allows for repeated casting of multiple aluminum lifting lugs, improving production efficiency. By setting up a support mechanism 200 and a limiting mechanism 300, the mold 400 is supported by the support mechanism 200 and the limiting mechanism 300 respectively in the casting and demolding states, improving the stability of the mold 400 in both states. Simultaneously, it ensures that the maximum flipping angle of the mold 400 remains consistent during repeated flipping, reducing the difficulty of manual operation and further improving production efficiency. By including the first connector 310 and the first protrusion 320 in the limiting mechanism 300, and when the mold 400 is in the demolding state, the mold 400 abuts against the first protrusion 320, and a gap is formed between the mold 400 and the first connector 310, the contact area between the mold 400 and the limiting mechanism 300 is reduced, the risk of finger pinching when the mold 400 is in the demolding state is reduced, and the safety of the flipping demolding device 10 is improved.
[0041] In some embodiments, the support mechanism 200 and the limiting mechanism 300 are located on both sides of the rotating shaft 500 in a first direction (x direction in the figure), which intersects the height direction z.
[0042] Optionally, the limiting mechanism 300 includes a plurality of first protrusions 320, which are spaced apart along a second direction (y-direction in the figure), with the first direction x, the second direction y, and the height direction z intersecting in pairs. For ease of understanding, the first direction x can be defined as the front-back direction, and the second direction y as the left-right direction. Preferably, there are two first protrusions 320, so that the first protrusions 320 can stably support the mold 400, and the gap between the first connecting member 310 and the mold 400 in the second direction y is sufficiently wide to ensure its anti-pinch function.
[0043] Optionally, the first protrusion 320 has a dimension of 20mm in the height direction z. When the mold 400 is in the demolding state, since the first protrusion 320, which protrudes relative to the first connector 310, abuts against the mold 400, a 20mm wide gap is formed between the first connector 310 and the mold 400, which can effectively prevent the operator's fingers from being pinched by the mold 400 and the first connector 310. Of course, in other embodiments, the height of the first protrusion 320 can be further increased, thereby reducing the probability of the operator's palm or arm being pinched.
[0044] The flipping and demolding device 10 of this application improves the supporting force of the limiting mechanism 300 on the mold 400 by arranging a plurality of first protrusions 320 at intervals along the second direction y, thereby improving the stability of the mold 400 in the demolding state. By adjusting the number of the first protrusions 320 and their width in the second direction y, it can both stably support the mold 400 and ensure that the gap between the first connecting member 310 and the mold 400 is sufficiently wide in the second direction y to guarantee its anti-pinch function.
[0045] In some embodiments, the flipping demolding device 10 further includes a bearing seat 510, which is sleeved on the rotating shaft 500 so that the rotating shaft 500 can rotate relative to the bearing seat 510. One of the bearing seat 510 and the rotating shaft 500 is connected to the base 100 and the other is connected to the mold 400.
[0046] In this embodiment, the bearing housing 510 is connected to the base 100, and the rotating shaft 500 is connected to the mold 400, with the mold 400 and the rotating shaft 500 rotating synchronously. In another embodiment, the bearing housing 510 is connected to the mold 400, and the rotating shaft 500 is connected to the base 100, with the mold 400 and the bearing housing 510 rotating synchronously.
[0047] Optionally, the base 100 is provided with multiple rollers 600 on the side away from the mold 400, so that the operator can use the rollers 600 to push the flipping demolding device 10, thereby improving the practicality of the flipping demolding device 10.
[0048] Optionally, the flipping demolding device 10 also includes a handle 700, which is connected to the mold 400. The operator can either flip the mold 400 using the handle 700 to switch the mold 400 between the casting state and the demolding state, or push the flipping demolding device 10 using the handle 700 and the roller 600.
[0049] In some embodiments, the cross-sectional area of the mold groove 410 gradually decreases along the direction away from the opening of the mold groove 410. This can be understood as the cross-sectional area of the mold groove 410 being such that when the opening of the mold groove 410 faces downwards, it facilitates easy demolding of the aluminum lifting lug from the mold groove 410.
[0050] Optionally, the projected shape of the mold groove 410 is U-shaped, and the formed aluminum lifting lug has an upper width of 60mm, a lower width of 50mm, a thickness of 35mm, a length of 650mm, an inner arc angle of R80mm, and an outer arc angle of R135mm. Of course, in other embodiments, the shape and specific dimensions of the mold groove 410 can be changed according to actual needs.
[0051] Optionally, the mold 400 is provided with a plurality of weight-reducing holes 440 penetrating the mold 400, the weight-reducing holes 440 being used to reduce the overall weight of the mold 400.
[0052] In some embodiments, the support mechanism 200 includes a second connector 210 and a second protrusion 220 connected to each other, the second connector 210 being connected to the base 100, and the second protrusion 220 being located on the side of the second connector 210 facing away from the base 100.
[0053] Optionally, the rotating shaft 500, the first connecting member 310, and the second connecting member 210 all extend along the second direction y. The first connecting member 310 and the second connecting member 210 can be at least one of the following profiles: round steel, round pipe, angle steel, square steel, channel steel, etc.
[0054] Optionally, the cross-sectional shape of the first protrusion 320 and the second protrusion 220 can be at least one of a circle, a polygon, or an irregular shape.
[0055] Optionally, the support mechanism 200 includes a plurality of second protrusions 220, which are spaced apart along the second direction y. Preferably, there are two second protrusions 220, so that the second protrusions 220 can stably support the mold 400 and the gap between the second connector 210 and the mold 400 is sufficiently wide in the second direction y to ensure its anti-pinch function.
[0056] The flipping and demolding device 10 of this application embodiment includes a second connector 210 and a second protrusion 220 in the support mechanism 200, and when the mold 400 is in the casting state, the mold 400 abuts against the second protrusion 220, and a gap is formed between the mold 400 and the second connector 210. This reduces the contact area between the mold 400 and the support mechanism 200, reduces the risk of finger pinching when the mold 400 is in the casting state, and further improves the safety of the flipping and demolding device 10.
[0057] In summary, the flipping and demolding device 10 provided in this application includes a base 100, a support mechanism 200, a limiting mechanism 300, and a mold 400. The support mechanism 200 is connected to the base 100. The limiting mechanism 300 and the support mechanism 200 are located on the same side of the base 100 in the height direction (z direction in the figure). The limiting mechanism 300 includes a first connecting member 310 and a first protrusion 320 that are connected to each other. The first connecting member 310 is connected to the base 100, and the first protrusion 320 is located on the side of the first connecting member 310 away from the base 100. A mold groove 410 is provided on one side of the mold 400. The mold 400 is rotatably connected to the base 100 through a rotating shaft 500, so that the mold 400 has a casting state and a demolding state that can be switched. In the casting state, the opening of the mold groove 410 is located on the side of the mold 400 away from the base 100, and the mold 400 abuts against the support mechanism 200. In the demolding state, the opening of the mold groove 410 faces the base 100, and the mold 400 abuts against the first protrusion 320, forming a gap between the mold 400 and the first connecting member 310. The flipping demolding device 10 of this embodiment allows the mold 400 to be rotatably connected to the base 100 via a rotating shaft 500, enabling the mold 400 to switch between a casting state and a demolding state. In the casting state, molten aluminum is poured. After the molten aluminum cools and solidifies, the mold 400 is rotated to switch to the demolding state, causing the opening of the mold groove 410 to face downwards, allowing the aluminum lifting lug to separate from the mold 400 and complete the demolding process. The operation is simple and allows for repeated casting of multiple aluminum lifting lugs, improving production efficiency. By setting up the support mechanism 200 and the limiting mechanism 300, the mold 400 is supported by the support mechanism 200 and the limiting mechanism 300 respectively when it is in the casting state and the demolding state, thereby improving the stability of the mold 400 in the casting state and the demolding state. At the same time, it ensures that the maximum flipping angle of the mold 400 is consistent during repeated flipping, reducing the difficulty of manual operation and thus improving production efficiency. By making the limiting mechanism 300 include the first connecting member 310 and the first protrusion 320, and making the mold 400 abut against the first protrusion 320 when it is in the demolding state, a gap is formed between the mold 400 and the first connecting member 310, reducing the contact area between the mold 400 and the limiting mechanism 300, reducing the risk of finger pinching when the mold 400 is in the demolding state, and thus improving the safety of the flipping demolding device 10.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
