[0002] Casting alloy ingot needs to be knocked off in production process, so that alloy ingot is separated from casting machine ingot mould, to ensure that the aluminum ingot is dropped off. In the existing casting machine, the knock ingot device is usually arranged at the end of the conveying line, and the knock hammer is driven by the cylinder to knock the alloy ingot in the mould, but for more solid alloy ingot, only the end of the knock cannot guarantee that the alloy ingot is completely dropped off, so artificial inspection is needed to ensure that it is completely separated. Meanwhile, the knock hammer directly knocks the surface of the ingot, which may cause damage to the surface of the ingot.

[0003] Therefore, there is an urgent need for a casting alloy ingot mould auxiliary stripping mechanism, which can effectively ensure that the ingot is completely dropped off and effectively avoid damage to the surface of the ingot caused by knocking. UTILITY MODEL CONTENT

[0019] The feasible implementations discovered in this field are as follows:

[0020] Patent publication number CN116900263A discloses an alloy ingot demolding device, including a casting mechanism comprising a support member, an output disk assembly and a driven gear disk rotatably mounted on the support member, a chain on the output disk assembly and the driven gear disk, an alloy ingot mold on the chain, and a driving member mounted on the support member; the support member comprising a pillar and a bearing sleeve mounted on the pillar; the output disk assembly comprising a positioning shaft rotatably mounted on the bearing sleeve and a turntable mounted on the positioning shaft, the turntable having toothed blocks and guide grooves; and a first demolding mechanism comprising a limiting sleeve mounted on the bearing sleeve and a guide member slidably mounted on the limiting sleeve, the guide member having an impact block, and a first spring sleeved outside the limiting sleeve.

[0021] This patented technology guides the guide column to slide through the guide groove and controls the impact block to impact the corresponding part of the alloy ingot mold for demolding. Since the toothed block and the alloy ingot mold correspond to each other, the impact block can accurately impact each alloy ingot mold regardless of the rotation speed of the turntable. Therefore, when the conveying speed of the alloy ingot mold changes, the frequency of the impact block will be adjusted synchronously without deviation, effectively improving the impact effect during demolding and making it convenient to use.

[0022] Patent publication number CN216028025U discloses an automatic demolding alloy casting device, including a casting mold disposed on a casting line. An impact roller is positioned in front of the demolding end of the casting line, and the distance between the impact roller and the casting line is less than the length of any casting mold. When the overlapping end of the casting mold flips downwards, it can collide with the impact roller. The connecting end of the casting mold is fixed to the running mechanism of the casting line, and the overlapping end is mounted on the connecting end of the previous casting mold. The impact roller is mounted on a corresponding bracket. The impact roller is an electric roller, connected to a control cabinet via wiring, which controls the rotational speed of the impact roller. The impact roller rotates in the opposite direction to the conveyor roller of the casting line, and the impact roller and the conveyor roller rotate towards each other. The rotational speed of the impact roller is the same as that of the conveyor roller.

[0023] This patented method uses a method where the casting mold for solidifying the alloy impacts an impact roller to dislodge the alloy ingot from the mold. This automatic demolding method does not use chemical release agents, is safe and environmentally friendly, and does not damage the alloy. The automatic demolding process is highly automated, requiring no operator intervention, saving manpower and improving work efficiency. The patented method uses an automatic control circuit to control the transmission of the impact roller, matching the rolling frequency with the transmission speed of the casting line to achieve optimal automatic demolding results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figs. 1-2 This utility model discloses an auxiliary demolding mechanism for casting alloy ingot molds, including a plurality of molds 10 arranged on the chain 9 of a chain casting machine. A vibration component for separating the alloy ingot in the mold 10 from the mold 10 is arranged below the chain 9 of the chain casting machine. A striking component for removing the alloy ingot from the mold 10 is arranged at one end of the chain casting machine. A conveying device 13 for conveying the alloy ingot is arranged below the striking component.

[0027] Chain casting machines are commonly used in casting processes. They connect the ingot and the cooling body via a chain 9, enabling continuous casting. The process typically involves pouring molten aluminum or other metal into a mold, which then moves at a constant speed along the chain track. After cooling and demolding, the ingot is finally formed.

[0028] The chain casting machine of this utility model has two sprockets connected to the chain 9. Each sprocket is connected to a drive motor 12. The drive motor 12 drives the sprocket to rotate, so that the chain 9 can move stably on the two sprockets.

[0029] The conveying device 13 is used to convey the alloy ingot that has been removed from the mold 10.

[0030] The conveying device 13 refers to machinery that continuously conveys bulk materials or packaged goods along a given route.

[0031] Based on whether or not they have flexible traction components, conveying devices can be divided into two categories:

[0032] Conveying devices with flexible traction components, such as belts and chains, place items on the traction component or inside the load-bearing component, and use the continuous movement of the traction component to transport the items in a certain direction. Examples include belt conveyors, plate conveyors, scraper conveyors, buried scraper conveyors, bucket elevators, cradle conveyors, aerial ropeways, escalators, and moving walkways.

[0033] Conveying devices without flexible traction components: These devices transport materials by utilizing the rotation or reciprocating motion of working components, such as screw conveyors, vibrating conveyors, and roller conveyors.

[0034] This invention first uses a vibration component to separate the alloy ingot from the inner wall of the mold, and then uses a striking component to strike the mold, which can detach the alloy ingot from the mold. This not only improves the detachment effect of the alloy ingot, but also effectively avoids damage to the surface of the alloy ingot from the striking.

[0035] Further optimization of the design includes a vibration assembly comprising a support plate fixedly connected to the frame of the chain casting machine. Several fixed ends of cylinders II11 are fixedly connected to the support plate, and the piston ends of cylinders II11 are used to strike the bottom of the mold 10. By striking the bottom of the mold 10 with the piston ends of cylinders II11, the alloy ingot inside the mold 10 can be separated from the inner wall of the mold 10.

[0036] The design was further optimized by arranging several cylinders II11 at equal intervals. This ensures that the mold 10 is subjected to uniform vibration, effectively improving the separation effect between the alloy ingot and the mold 10.

[0037] A cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy, and it is widely used in various industrial automation equipment. It typically consists of a cylinder barrel, end caps, piston, piston rod, and seals. Its internal structure allows the piston to perform linear reciprocating motion within the cylinder barrel. The working principle of a cylinder is based on the compressibility of air; by controlling the intake and exhaust of air, the movement of the piston is achieved, thereby driving external equipment or performing specific work tasks.

[0038] Further optimizing the design, the striking assembly includes a gantry bracket 8 mounted at the end of the chain casting machine. The fixed ends of cylinder I1 are rotatably connected to both sides of the gantry bracket 8 via positioning rings 2. A connecting rod 3 is hinged to the piston end of cylinder I1. One end of the connecting rod 3 is rotatably connected to the gantry bracket 8 via a support, and the other end of the connecting rod 3 is fixedly connected to a striking hammer 4. By installing the gantry bracket 8 at the end of the chain casting machine, the striking hammer 4 can effectively strike the mold 10 and the alloy ingot under the drive of cylinder I1.

[0039] The design was further optimized so that the hammer 4 includes a buffer plate 5, and several springs 6 are fixedly connected between the buffer plate 5 and the two connecting rods 3. The buffer plate 5 can effectively reduce the damage to the surface of the alloy ingot caused by the hammering.

[0040] In order to enable the buffer plate 5 to stably and effectively strike the mold 10 and the alloy ingot, the buffer plate 5 is symmetrically provided with sliders 7 on one end facing the connecting rod 3. The sliders 7 are fixedly connected to the buffer plate 5 and are slidably connected with grooves. The grooves are respectively opened on the opposite sides of the two connecting rods 3. By limiting the sliders 7 through the grooves, the sliders 7 can only move along the grooves, so that the buffer plate 5 can effectively strike the mold 10 and the alloy ingot.

[0041] The design was further optimized so that the length of the buffer plate 5 is matched with the width of the mold 10. This effectively increases the contact area between the buffer plate 5 and the mold 10, allowing the alloy ingot inside the mold 10 to be subjected to even impact.

[0042] The design was further optimized so that the size of the buffer plate 5 is larger than the cross-sectional size of the end of the connecting rod 3 facing the mold 10. This allows the buffer plate 5 to cover the two connecting rods 3, enabling the connecting rods 3 to stably move the buffer plate 5.

[0043] Further optimization of the design: the connecting rod 3 is L-shaped, with the shorter end of the connecting rod 3 fixedly connected to the spring 6, and the longer end of the connecting rod 3 rotatably connected to the support. The piston end of cylinder I is positioned close to the support. When cylinder I pushes the longer end of the connecting rod 3, it can cause the shorter end of the connecting rod 3 to swing over a wide range with a small extension / retraction length, allowing the buffer plate 5 to effectively strike the mold 10.

[0044] Working process: During use, the drive motor 12 drives the sprocket to rotate, and the conical teeth of the sprocket mesh with the chain 9, which drives the mold 10 to move. When the mold 10 moves above the cylinder II 11, the piston end of the cylinder II 11 extends and retracts, causing the piston end of the cylinder II 11 to strike the bottom of the mold 10, causing the alloy ingot inside the mold 10 to separate from the inner wall of the mold 10. When the mold 10 moves to the striking hammer 4, the cylinder I 1 drives the striking hammer 4 to move through the connecting rod 3. Through the striking of the striking hammer 4, the alloy ingot can be completely separated from the mold 10, which facilitates the smooth demolding of the alloy ingot. After the alloy ingot is removed from the mold 10, it is transported by the conveying device 13.

[0045] This invention effectively separates the ingot from the mold by using the vibration of cylinder II11. At the same time, the knocking of cylinder I1 can effectively separate the demolded ingot in a timely manner. A buffer plate is set on the knocking hammer to prevent the knocking hammer from directly contacting the ingot and causing the ingot to break. This effectively ensures the integrity of the surface of the ingot with poor brittleness.

[0046] This utility model uses a cylinder I1 to drive a hammer. The power generated by the chain conveyor can drive the cylinder to work and strike the alloy ingot on the mold at the end of the conveyor. This ensures that the alloy ingot can be smoothly removed from the mold. The striking effect is good and no striking points are left on the surface of the alloy ingot, which would affect the surface quality. It also avoids alloy ingots that cannot be removed from the mold from returning to the casting area with the conveyor, which would affect work efficiency. This saves manpower, improves work efficiency, and ensures stable production.
