Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a casting iron film sand-coating and unpacking machine. Background Technology

[0002] Iron mold sand casting, a precision casting method that combines the advantages of metal molds and sand casting, has been widely used in industrial production in recent years. The temperature of the iron mold after pouring can reach 350-400℃. This process improves the surface quality of the casting and accelerates the cooling rate by covering the surface of the iron mold with a thin layer of sand (sand coating).

[0003] However, the traditional unpacking process usually relies on natural cooling, which is inefficient. In addition, manual operation in high-temperature environments not only increases labor intensity but also poses significant safety hazards and can easily cause personal injury.

[0004] Secondly, because the sand coating layer on the iron mold is relatively thin, the casting cools down quickly, which makes the casting prone to uneven stress distribution during the cooling process, leading to easy cracking of the components.

[0005] Therefore, to overcome the aforementioned problems, it is urgent to develop a new and efficient mold-opening method that can improve cooling efficiency, reduce the risk of casting cracking, and ensure the quality and precision of castings while ensuring operational safety. By improving existing mold-opening techniques and optimizing the casting process, the overall efficiency of iron mold sand casting can be significantly enhanced, promoting technological progress and development in related industries.

[0006] Therefore, this application provides a casting iron film sand-coated box opening machine to overcome the defects of the prior art. Utility Model Content

[0007] The purpose of this invention is to solve the problems of low cooling efficiency, easy cracking, and dangerous operation in existing unpacking methods.

[0008] This utility model provides a casting iron film sand-coating box opening machine, including a cooling mechanism, a box opening mechanism on one side of the cooling mechanism, a thermometer between the cooling mechanism and the box opening mechanism, the thermometer being an infrared thermometer for real-time temperature monitoring, a transport mechanism, a bottom of the thermometer being fixedly connected to the top of the transport mechanism, a sand box being placed on the transport mechanism, and a controller for controlling the operation of the motors, telescopic parts, thermometers and other equipment in each mechanism.

[0009] The controller is a PLC controller, using Siemens PLC and HMI touch screen, integrating temperature monitoring, hydraulic control and fault alarm functions to achieve fully automated operation. When the sand box temperature drops below 150℃, the opening program is automatically triggered to control the opening mechanism. The temperature-action linkage logic ensures accurate opening timing and reduces scrap rate.

[0010] The cooling mechanism includes a support frame, with an upper fixed plate fixed to the top of the support frame. A plurality of upper nozzles, facing downwards, are fixed to the bottom of the upper fixed plate. A lower fixed plate is fixed within the support frame, positioned below the upper fixed plate. A plurality of lower nozzles, also facing upwards, are fixed to the top of the lower fixed plate. A sand box is positioned between the upper and lower fixed plates. A thermometer is used to detect the temperature of the sand box within the cooling mechanism. When the sand box temperature meets the requirements, a transport mechanism operates to move the sand box to the unpacking mechanism. The atomizing nozzle is driven by compressed air to uniformly cool the iron mold (cooling rate up to 50℃ / min), avoiding thermal stress. The atomizing cooling technology shortens the cooling time to 1 / 3 of the traditional method, increasing the production line speed. The nozzle is connected to an external water tank through pipelines. Water from the tank enters the nozzle through the pipelines and sprays the sand box. The pipelines are equipped with valves and water pumps. The controller can control the opening and closing of the water pumps and valves. This is a mature existing technology with many practical applications, which will not be elaborated here.

[0011] The unpacking mechanism includes a second bracket, a first connecting plate, and two telescopic components fixed to the top of the first connecting plate. The first telescopic components are horizontally arranged and back to back. The output ends of the two first telescopic components are located at the ends of the first telescopic components that are far away from the other. Each output end of the first telescopic component is fixed with a baffle. The bottom of each baffle is fixed with two grippers that are L-shaped.

[0012] It also includes a telescopic component 2, which is set on the top of the bracket 2. The output end of the telescopic component 2 faces upward. A baffle 2 is fixed to the top of the output end of the telescopic component 2. Four guide rods 1 arranged opposite to each other are fixed to the bottom of the baffle 2. The bottom of the guide rods 1 is fixedly connected to the top of the connecting plate 1.

[0013] It also includes two guide rods 2 arranged opposite each other. The two ends of the guide rods 2 are fixed with blocks. The bottom of the blocks is fixedly connected to the top of the connecting plate 1. The guide rods 2 are slidably connected to the baffle 1.

[0014] A connecting plate is fixed to the side of the bottom of the baffle plate away from the telescopic component.

[0015] The telescopic component can be a cylinder, a hydraulic cylinder, or other equipment capable of performing this function. In this device, the telescopic component is a cylinder.

[0016] The transport mechanism includes two opposing connecting plates. On the side of one connecting plate away from the other, there are a plurality of evenly distributed gears. Each gear is fixedly connected to a rotating shaft on the side closest to the connecting plate. The rotating shaft passes through the connecting plate and is rotatably connected to it. A portion of the rotating shaft is located between the two connecting plates. Each rotating shaft is fitted with a connecting shaft, which is rotatably connected to the connecting shaft. The connecting shaft is fixedly connected to the inner wall of the connecting plate. The rotating shaft portion is exposed on the outer side of the connecting shaft. In addition, the device also includes a motor. A transmission gear is fixed to the output end of the motor. The transmission gear meshes with the gear chain. The motor drives the gear to rotate through the transmission gear and the gear chain, thereby driving the rotating shaft to rotate, and thus moving the sand box.

[0017] The sand box includes an upper box body, with baffle four fixed around the outer perimeter of the upper box body. A lower box body is provided below the upper box body, with baffle five fixed around the outer perimeter of the lower box body. Baffle five is located inside the connecting shaft and placed on the rotating shaft. The bottom of baffle five is in contact with the top of at least four rotating shafts, and the bottom sides of baffle five are in contact with the top of at least two rotating shafts respectively. The box body is located between the rotating shafts.

[0018] The beneficial effects of the casting iron film sand-coating box-opening machine provided by this utility model are:

[0019] This utility model, by setting a cooling mechanism, can spray atomized water to uniformly cool the iron mold, improve cooling efficiency, reduce thermal stress, reduce the risk of cracking, and use atomized nozzles for cooling to shorten cooling time and improve production efficiency.

[0020] By setting an opening mechanism, the box can be opened automatically, and the upper box can be lifted vertically to avoid hitting the castings when opening the box;

[0021] By setting up a temperature sensor to monitor the temperature of the iron mold in real time, we can avoid insufficient or excessive cooling.

[0022] By setting up controller-controlled unpacking, cooling, and transport mechanisms, the entire process can be completed without worker intervention, reducing production risks. Attached Figure Description

The nozzles are... The atomizing nozzle, driven by compressed air, provides uniform cooling to the iron mold (cooling rate up to 50℃ / min), avoiding thermal stress. This atomizing cooling technology reduces cooling time to one-third of traditional methods, increasing production line speed. The nozzle is connected to an external water tank via pipelines, allowing water from the tank to enter the nozzles and spray the sand box 5. The pipelines contain valves and a water pump, and a controller 6 controls the opening and closing of the pumps and valves.

[0041] The transport mechanism 4 includes two opposing connecting plates 41. A plurality of evenly distributed gears 42 are provided on the side of each connecting plate 41 away from the other connecting plate 41. Each gear 42 is fixedly connected to a rotating shaft 43 on the side closest to the connecting plate 41. The rotating shaft 43 passes through the connecting plate 41 and is rotatably connected to it. A portion of the rotating shaft 43 is located between the two connecting plates 41. A connecting shaft 44 is fitted onto each rotating shaft 43, and the rotating shaft 43 is rotatably connected to the connecting shaft 44. The connecting shaft 44 is fixedly connected to the inner wall of the connecting plate 41, and a portion of the rotating shaft 43 is exposed on the outer side of the connecting shaft 44. In addition, the device also includes a motor. A transmission gear is fixed to the output end of the motor. The transmission gear meshes with the gear 42 via a toothed chain. The motor drives the gear 42 to rotate through the transmission gear and toothed chain, thereby driving the rotating shaft 43 to rotate, and thus moving the sand box 5.

[0042] The sand box 5 includes an upper box body 51, with baffles 4 52 fixed around the outer perimeter of the upper box body 51.

[0043] Working procedure: After the molten iron is poured into the sand box 5, the sand box 5 is placed on the rotating shaft 43. The transport mechanism 4 is started by the controller 6, and the rotating shaft 43 moves the sand box 5 to the cooling mechanism 1. The temperature sensor 2 detects the temperature of the sand box 5. If the temperature is higher than the set temperature, the controller 6 controls the upper nozzle 13 and the lower nozzle 15 to spray the sand box 5 to cool it down. When the temperature sensor 2 detects that the temperature of the sand box 5 is not higher than the set temperature, the controller 6 restarts the transport mechanism 4 and sends the cooled sand box 5 to the unpacking mechanism 3. In the middle, the telescopic component 2 36 is activated, which drives the gripper 35 to move downward through the baffle 2 37, guide rod 1 38 and connecting plate 1 32. At the same time, the output shaft in the telescopic component 1 33 extends, so that the gripper 35 moves away from the sand box 5. The gripper 35 moves to a suitable position, and the output shaft in the telescopic component 1 33 retracts, so that the gripper 35 moves towards the sand box 5 and clamps the baffle 4 52. Then, the telescopic component 2 36 is activated, which drives the gripper 35 to move upward through the baffle 2 37, guide rod 1 38 and connecting plate 1 32. The upper box 51 is then lifted through the baffle 4 52.
