Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy die casting technology, specifically an aluminum alloy die casting machine. Background Technology

[0002] Die casting machines are a series of industrial casting machines that use pressure to inject molten metal into a mold to cool and solidify it, resulting in a solid metal casting after the mold is opened. Initially used for die casting lead type, die casting technology has developed extremely rapidly with the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles, and home appliances.

[0003] A patent with publication number CN117862456A discloses an aluminum alloy die-casting machine, including a machine body. A protective door is provided on one side of the machine body, and a material picking mechanism is provided on the protective door. The material picking mechanism includes a support base and two clamping plates. A support shaft is provided through the support base, and the support shaft is movably connected to the support base through a bearing. A material picking seat is fixed on the support column, and a first sliding groove is opened on the surface of the material picking seat. Both clamping plates are slidably connected to the first sliding groove. A frame is provided on one side of the machine body, and a first transmission belt is provided above the frame. A cooling mechanism is provided above the first transmission belt. This invention solves the problems of existing technologies where using a robotic arm for material unloading is space-consuming and costly, and where the temperature of newly die-cast aluminum alloy workpieces is high. If they are not cooled and directly piled up, it will further make it difficult for workers to move the workpieces.

[0004] In current technologies, when die-casting aluminum alloys, if sheet metal is used directly, the deformation of the sheet metal generates heat due to the deformation of the rigid material. While the heat generated by a single sheet is relatively small, it is directly transferred to the interior of the mold. As the number of sheet metal pieces increases, the heat transfer also increases, leading to a continuous increase in the temperature inside the mold. When aluminum alloy molten steel is poured into the mold, the heat generated is directly transferred to the interior of the mold. The extremely high temperature of the molten steel prevents the mold from quickly dissipating the heat, causing the internal temperature of the mold to be transferred in the opposite direction to the surface of the aluminum alloy. This can result in burns to employees when handling or dropping the aluminum alloy.

[0005] Therefore, an aluminum alloy die-casting machine is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, an aluminum alloy die-casting machine is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The aluminum alloy die casting machine of this utility model includes a die casting processing table. A limiting groove is formed on the top surface of the die casting processing table. A material discharge guide chute is fixedly connected to the bottom surface of the die casting processing table. A material discharge groove is formed at the connection between the material discharge guide chute and the die casting processing table. A blower extending to the inner wall of the material discharge guide chute is fixedly installed on the bottom surface of the die casting processing table. A closed mold plate is movably overlapped on the top surface of the die casting processing table. A limiting overlap plate that is movably sleeved on the inner wall of the limiting groove is fixedly connected to the bottom surface of the closed mold plate. A back side of the closed mold plate is provided with...

[0008] Preferably, a fixing plate 2 is fixedly connected to the top surface of the die-casting processing table and located at one side edge, and a support table is fixedly installed on the top surface of the die-casting processing table and located at the other side edge.

[0009] Preferably, four sets of limiting support rods are fixedly installed on the inner wall of the second fixing plate and the support platform, and a support column is fixedly connected to the outer surface of the second fixing plate, with a mold fixedly connected to one end of the support column.

[0010] Preferably, the outer surface of the mold and the closed mold plate is movably sleeved on the outer surface of the limiting support rod, an aluminum alloy injection tube is fixedly connected to the top surface of the mold, and the outer surface is fixedly connected to the outer surface of the support platform.

[0011] Preferably, hydraulic rods are fixedly installed on the outer surface of the second fixing plate and the support platform at the middle position, and die-casting grooves are respectively opened on the inner wall of the mold and the closed mold plate.

[0012] Preferably, the output ends of the hydraulic rods extend to the inner wall of the die-casting tank, and a peeling plate that is movably sleeved on the inner wall of the die-casting tank is fixedly connected to the output ends of the hydraulic rods.

[0013] Preferably, a swing closing plate is provided on the bottom surface of the material discharge chute, and four sets of fixing plates are fixedly installed on the bottom surface of the die casting processing table.

[0014] Preferably, a motor is fixedly installed on one end of the fixing plate, and a conveyor belt is movably sleeved on the outer surface of the output end of the motor.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides an aluminum alloy die-casting machine. When the sheet metal falls into the material discharge chute, it is pushed by a closed mold plate, causing the limiting overlap plate on the bottom surface of the closed mold plate to slide from the inside of the limiting slide. Under the action of the limiting overlap plate, the top surface of the material discharge chute is sealed, making the inside of the material discharge chute a closed state. Then, a blower circulates gas into the inside of the material discharge chute. The rapid circulation of the gas quickly removes the heat source from the surface of the sheet metal, keeping the sheet metal at room temperature. This achieves the effect of cooling the sheet metal by rapidly flowing room temperature gas inside the closed state to remove the heat source from the surface of the sheet metal.

[0017] This utility model provides an aluminum alloy die-casting machine that uses a closed mold plate to push and align the mold and the closed mold plate. Molten aluminum alloy is injected into the die-casting tank through an aluminum alloy injection pipe. After the molten aluminum alloy solidifies, the closed mold plate is pulled back. At this point, any sheet metal remaining inside the die-casting tank, whether in the mold or the closed mold plate, is pushed out of the die-casting tank by a hydraulic rod using a peeling plate. This achieves the effect of automatically peeling out sheet metal regardless of whether it remains in the mold or the closed mold plate. If the sheet metal remains on the outer surface of the fixed plate, an employee can use a push rod to squeeze and push the sheet metal, causing it to fall through the discharge chute into the discharge guide chute for recycling.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 - Figure 6 This utility model provides an aluminum alloy die casting machine, including a die casting processing table 11. A limiting groove 112 is formed on the top surface of the die casting processing table 11. A material discharge guide chute 116 is fixedly connected to the bottom surface of the die casting processing table 11. A material discharge groove 111 is formed at the connection between the material discharge guide chute 116 and the die casting processing table 11. A blower 118 extending to the inner wall of the material discharge guide chute 116 is fixedly installed on the bottom surface of the die casting processing table 11. A closed mold plate 128 is movably overlapped on the top surface of the die casting processing table 11. A limiting overlap plate 1210 is fixedly connected to the bottom surface of the closed mold plate 128 and movably sleeved on the inner wall of the limiting groove 112. A 1211 is provided on the back of the closed mold plate 128.

[0029] During operation, when the sheet metal falls into the material discharge chute 116, it is pushed by 1211 to close the mold plate 128, causing the limiting overlap plate 1210 on the bottom surface of the mold plate 128 to slide from the inside of the limiting slide groove 112. Under the action of the limiting overlap plate 1210, the top surface of the material discharge chute 116 is sealed, making the inside of the material discharge chute 116 a closed state. Then, the blower 118 circulates gas into the inside of the material discharge chute 116. The rapid circulation of the gas quickly removes the heat source from the sheet metal surface, keeping the sheet metal at room temperature. This achieves the effect of cooling the sheet metal surface by rapidly flowing room temperature gas within the closed state.

[0030] Furthermore, such as Figures 1 to 3 and Figure 6 As shown, a swing closing plate 117 is provided on the bottom surface of the material discharge and diversion chute 116, and four sets of fixing plates 113 are fixedly installed on the bottom surface of the die casting processing table 11. A motor 114 is fixedly installed on one end of the fixing plate 113, and a conveyor belt 115 is movably sleeved on the outer surface of the output end of the motor 114.

[0031] When the sheet metal inside the discharge chute 116 is rapidly cooled by the blower 118, and the mold 122 and the closing mold plate 128 are closed, molten aluminum alloy steel can be injected into the die-casting tank 129. After the sheet metal is die-cast, it swings in conjunction with the swing closing plate 117, causing the sheet metal inside to automatically fall onto the top surface of the conveyor belt 115. Driven by the motor 114, the employee retrieves it. While retrieving the sheet metal, new sheet metal will fall back into the discharge chute 116. This achieves the effect that the discharge chute 116 forms a closed state every time the mold die-casts sheet metal, thereby cooling the previous sheet metal without the need for separate cooling of the sheet metal and shortening the sheet metal cooling time.

[0032] Furthermore, such as Figures 1 to 6As shown, a fixing plate 12 is fixedly connected to the top surface of the die-casting processing table 11 and located at one edge. A support platform 125 is fixedly installed on the top surface of the die-casting processing table 11 and located at the other edge. Four sets of limiting support rods 124 are fixedly installed on the inner wall surfaces of the fixing plate 12 and the support platform 125. A support column 121 is fixedly connected to the outer surface of the fixing plate 12. A mold 122 is fixedly connected to one end of the support column 121. The outer surfaces of the mold 122 and the closed mold plate 128 are movably sleeved on the outer surfaces of the limiting support rods 124. An aluminum alloy injection pipe 123 is fixedly connected to the top surface of the mold 122. The outer surface of the mold 1211 is fixedly connected to the outer surface of the support platform 125. A hydraulic rod 126 is fixedly installed on the outer surface of the fixing plate 12 and the support platform 125 at the middle position. A die-casting groove 129 is opened on the inner wall of the mold 122 and the closed mold plate 128. The output end of the hydraulic rod 126 extends to the inner wall of the die-casting groove 129. A peeling plate 127 is fixedly connected to the output end of the hydraulic rod 126 and is movably sleeved on the inner wall of the die-casting groove 129.

[0033] The hydraulic rod 1211 pushes the closed mold plate 128, causing the mold 122 and the closed mold plate 128 to align. Molten aluminum alloy steel is then injected into the die-casting tank 129 via the aluminum alloy injection pipe 123. After the molten aluminum alloy steel solidifies, the closed mold plate 128 is pulled back using the hydraulic rod 1211. At this point, any sheet metal remaining inside the die-casting tank 129, whether in the mold 122 or the closed mold plate 128, will be pushed by the hydraulic rod 126 onto the stripping plate 127, causing the sheet metal to fall out of the die-casting tank 129. This achieves the effect of automatically stripping sheet metal from either the mold 122 or the closed mold plate 128 using the hydraulic rod 126. If sheet metal remains on the outer surface of the fixed plate 12, an employee can use a push rod to squeeze and push the sheet metal, causing it to pass through the discharge chute 111 and fall into the discharge guide chute 116 for recycling.

[0034] Working principle: The system works by pushing the closed mold plate 128 with 1211, causing the mold 122 and the closed mold plate 128 to align. Molten aluminum alloy is injected into the die-casting tank 129 through the aluminum alloy injection pipe 123. After the molten aluminum alloy solidifies, 1211 pulls the closed mold plate 128 back. At this point, any sheet metal remaining inside the die-casting tank 129, whether in the mold 122 or the closed mold plate 128, will be pushed by the hydraulic rod 126 onto the peeling plate 127, causing the sheet metal to fall out of the die-casting tank 129. This achieves the effect of automatically peeling out sheet metal regardless of whether it remains in the mold 122 or the closed mold plate 128. If the sheet metal remains on the outer surface of the fixed plate 12, an employee can use a push rod to squeeze and push the sheet metal, causing it to pass through the discharge chute 111 and fall into the discharge guide chute 116 for recycling.

[0035] After the sheet metal falls into the material discharge chute 116, it is pushed by 1211 to close the mold plate 128, and the limiting overlap plate 1210 on the bottom surface of the mold plate 128 slides from the inside of the limiting slide groove 112. Under the action of the limiting overlap plate 1210, the top surface of the material discharge chute 116 is closed, so that the inside of the material discharge chute 116 is in a closed state. Then, the blower 118 circulates gas into the inside of the material discharge chute 116. The rapid circulation of gas quickly removes the heat source from the surface of the sheet metal and keeps the sheet metal at room temperature. This achieves the effect of cooling the sheet metal by rapidly flowing room temperature gas in a closed state to remove the heat source from the surface of the sheet metal.

[0036] When the sheet metal inside the discharge chute 116 is rapidly cooled by the blower 118, and the mold 122 and the closing mold plate 128 are closed, molten aluminum alloy steel can be injected into the die-casting tank 129. After the sheet metal is die-cast, it swings in conjunction with the swing closing plate 117, causing the sheet metal inside to automatically fall onto the top surface of the conveyor belt 115. Driven by the motor 114, the employee retrieves it. While retrieving the sheet metal, new sheet metal will fall back into the discharge chute 116. This achieves the effect that the discharge chute 116 forms a closed state every time the mold die-casts sheet metal, thereby cooling the previous sheet metal without the need for separate cooling of the sheet metal and shortening the sheet metal cooling time.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
