Description

Technical Field

[0001] The present invention relates to the technical field of copper plate casting, and in particular to a casting device and method for producing and processing copper plates. Background Art

[0002] In the field of metal casting, the production of copper plates is a key link in high-precision industries such as electronics, aerospace, and heat exchanger manufacturing. Traditional casting processes usually use a melting furnace to melt copper materials at high temperatures. After the materials reach a liquid state, they are poured into a preformed metal mold by gravity pouring. After the casting liquid cools and solidifies, they are demolded and formed.

[0003] During the gravity pouring process, the copper melt fills the mold at a low flow rate and lacks external pressure. Dissolved gases (especially hydrogen) in the copper melt tend to precipitate and form bubbles due to the sudden drop in temperature, causing their solubility to decrease. Simultaneously, gases (such as H₂O and CO₂) generated by the high-temperature decomposition of residual moisture, scale, and other impurities within the mold cavity also accumulate in the copper melt. Due to limitations in the mold exhaust system design, these gases are trapped at the solidification front of the copper melt, forming pores with diameters ranging from microns to millimeters. These pores not only lead to a rough surface and localized mechanical weakness in the copper sheet, compromising its quality, but can also cause crack propagation or seal failure during subsequent processing (such as welding and stamping). Furthermore, the thickness of existing fixed molds is determined by the fixed spacing between the upper and lower molds. Adjusting the casting thickness of the copper sheet requires machining. Large thickness deviations require additional material removal, increasing costs. Summary of the Invention

[0004] In view of this, the present invention provides a casting device and method for the production and processing of copper plates, which can overcome the problem that the solubility of the gas dissolved in the copper liquid decreases due to a sudden drop in temperature, and tends to precipitate to form bubbles, which will cause the surface of the copper plate to be rough and the mechanical properties to be locally weak, affecting the quality of the copper plate. In addition, the thickness of the current fixed mold is determined by the fixed distance between the upper and lower molds. If the casting thickness of the copper plate needs to be adjusted, the copper plate can only be thinned by machining. In the case of a large thickness deviation, more material needs to be removed, which increases the cost.

[0005] The technical solution is as follows: A casting device for producing and processing red copper plates, comprising a frame, a mounting frame, a melting furnace, a heater, a solenoid valve, a material guide box, a casting box, a cylinder, a movable frame, a baffle, a sliding frame, an extrusion box, a spring, a limiting mechanism and a blocking mechanism.

Four springs 13 are provided on the sliding frame 11, and the two ends of the spring 13 are respectively connected to the sliding frame 11 and the extrusion box 12. The spring 13 is sleeved on the sliding frame 11 to prevent the spring 13 from bending.

The sealing plate 153 seals the bottom of the casting box 7 to prevent the copper liquid from leaking. The feeding amount of the copper liquid can be controlled according to the casting thickness of the copper plate. If the casting thickness of the copper plate is large, the feeding amount of the copper liquid can be increased, otherwise, the feeding amount of the copper liquid can be reduced. After the casting box 7 is filled with an appropriate amount of copper liquid, the solenoid valve 5 is controlled to be closed, and then the telescopic rod of the cylinder 8 is controlled to be shortened, driving the movable frame 9 to move downward, and the movable frame 9 drives the baffle 10, the sliding frame 11, the extrusion box 12 and the contact block 141 to move downward, and the baffle 10 and the extrusion box 12 will enter the casting box 7, and the extrusion box 12 will squeeze the copper liquid in the casting box 7 to discharge the bubbles in the copper liquid, thereby avoiding the surface roughness and local weakness of the mechanical properties of the copper plate, ensuring the quality of the copper plate, and the excess copper liquid flows back to the guide In the material box 6, when the contact block 141 moves downward and contacts the limit block 144, the contact block 141 stops moving downward, the extrusion box 12 also stops moving downward, the movable frame 9 and the baffle 10 continue to move downward, the spring 13 is compressed, and the baffle 10 can block the left side of the material guide box 6, so that the copper liquid in the material guide box 6 no longer flows into the casting box 7, and the copper liquid is cast into copper plates in the casting box 7. After the casting is completed, the output shaft of the stepping motor 152 is controlled to rotate, driving the blocking plate 153 to rotate downward, opening the bottom of the casting box 7, and the casting is completed. The copper plate falls from the casting box 7, and under the action of the spring 13, the extrusion box 12 will move downward. The extrusion box 12 can push the cast copper plate to prevent the cast copper plate from being stuck in the casting box 7. The screw motor 143 can drive the limit block 144 to move up and down, adjust the distance between the limit block 144 and the contact block 141, and control the downward movement distance of the extrusion box 12, so as to control the casting thickness of the copper plate.
