Description

Technical Field

[0001] This invention belongs to the field of metal casting and relates to an automatic casting system, and more specifically, to an automatic casting system for rare and dispersed metals, especially indium. Background Technology

[0002] Casting is a common production process for rare dispersed metals. As the application of rare dispersed metals becomes more widespread, the requirements for their shape are becoming increasingly stringent. Due to the physical properties of rare dispersed metals and the limited number of companies producing such products, there are currently no mature processes or equipment available on the market for producing such products. However, casting is an essential process step.

[0003] The current casting process mostly involves melting the raw materials in a furnace and then pouring them into a mold. However, this casting process has the following problems: (1) Transferring molten metal is time-consuming and labor-intensive, requiring a lot of manual operation. During the operation, there is a high risk of molten metal spilling and splashing, which can burn workers. (2) The casting mold needs to be preheated separately and the material needs to be poured and weighed at the same time during casting. One person cannot operate it, which results in a waste of manpower. Summary of the Invention

Multiple second sensors are provided, including a second sensor ① monitoring the conveying position and a second sensor ② monitoring the heating area.

[0086] The operating principle of the automatic casting system in this embodiment is as follows:

[0087] (1) Place the mold in the second mold tray, turn on the second turntable, so that the second mold tray enters the mold oven, and heat the mold in the second mold tray through the fan-shaped heating tunnel in the mold oven. Use the second turntable to rotate and transport the mold, and control the transport speed so that the mold is heated evenly in the fan-shaped heating tunnel.

[0088] (2) When the second mold plate is transported by the second turntable to the position directly in front of the push rod in the conveying area, the second sensor senses the second mold plate and stops the rotation of the second turntable; at the same time, the first rotary motor is started to drive the first turntable to rotate. At this time, as the first mold plate rotates and approaches the casting area, the mold cover is opened through the opening track. When the first mold plate is transported to the casting area, the rotation of the first turntable is stopped; at this time, the second mold plate and the first mold plate are set close together.

[0089] Activate the mold pusher device to push the mold from the second groove of the second mold plate along the guide groove to the first groove of the first mold plate;

[0090] (3) When the first sensor senses that the mold has reached the first groove of the first mold plate, the weighing device is started, the lifting drive module is turned on to make the weighing module weigh the first mold plate, automatically tare, and then the discharge valve of the melting furnace is opened. When the set weight is reached, the discharge valve of the melting furnace is automatically closed.

[0091] (4) When the discharge valve is closed, the weighing device is turned off, the lifting drive module returns to the initial position, and the first turntable is started to rotate. As the first mold plate rotates away from the casting area, the mold cover is closed through the cover track to avoid oxidation of the cast product during the molding process and ensure a smooth surface.

[0092] (5) The first turntable continues to rotate. When the first sensor senses that the first mold plate has reached the cooling position, the first turntable stops rotating, the water inlet valve is opened, and cooling water is injected into the first mold plate. The flow meter measures the flow. After the set capacity is reached, the first mold plate is automatically closed to complete the casting cooling process.

[0093] (6) The first turntable continues to rotate. When the first sensor detects that the first mold plate has rotated to the drain position above the lower water tank, the drain valve is opened.

[0094] (7) The first turntable continues to rotate until the mold cover lifting support handle enters the opening track, and the mold cover is opened to the extent that the cast mold can be taken out and demolded to complete the entire casting process.

[0095] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of the present invention.
