Description

Technical Field

[0001] The present invention relates to the technical field of metal casting, and more particularly to a precision casting gate cutting machine. Background Art

[0002] Precision castings refer to castings with complex shapes, precise dimensions and high surface finish that are manufactured through precision molds using advanced casting processes and equipment. The process flow of precision castings mainly includes mold manufacturing, smelting, injection, cooling, demoulding, cleaning and processing. After the precision castings are demoulded, the staff needs to cut the gate on the casting to separate the gate from the casting, and then carry out the next step of cleaning and processing on the casting;

[0003] However, when cutting the gate of a precision casting in the prior art, only the outer wall temperature of the gate of the precision casting is reduced to room temperature, while the internal temperature is still at a high temperature, which is prone to cracks during cutting, causing the entire casting to deform and burrs to be generated, thus affecting the product quality of the precision casting.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention accumulates clean water in a water storage box.

When the clean water flows on the inner wall of the water storage box, a water wall is formed to shield and cool the generated sparks, which is not only convenient for collecting the welding slag formed by cooling, but also prevents sparks from splashing and injuring surrounding operators.

[0020] 3. In the present invention, when the sewage in the water storage box is drained, the floating box drives the lifting rod to descend due to the influence of gravity, which not only drives the second piston to separate from the output end of the first suction pipe and the input end of the second suction pipe, but also cooperates with the second lever to drive the sealing cover to block the suction head. The air pump draws out the air in the drying box, so that the first suction pipe draws out the air under the display table, thereby accelerating the air flow rate under the filter, which is convenient for accelerating the drying of the surface of the precision casting.

[0042] The L-shaped air suction pipe 49 cooperates with the air suction head to absorb the generated harmful gases into the filter box 41 to prevent the health of the surrounding operators from being affected; the clean water in the water storage box 8 pushes up the floating box 485, so that the lifting rod 486 drives the second piston 47 to block the output end of the first air suction pipe 46, thereby preventing the clean water in the water storage box 8 from being sucked into the drying box 43;

A sealing cover 487 is fixedly connected to the end of the connecting plate 482, and the sealing cover 487 cooperates with the L-shaped air intake pipe 49.

[0044] When the sewage in the water storage box 8 is completely drained, the floating box 485 drives the lifting rod 486 to descend due to the influence of gravity, the sealing cover 487 blocks the suction head, and the air pump 42 evacuates the air in the drying box 43, so that the first suction pipe 46 evacuates the air under the display table 7, thereby accelerating the air flow rate under the filter screen 6, which is convenient for accelerating the drying of the surface of the precision casting;

[0046] It can be known from the present invention in combination with Example 1 and Example 2 that: by controlling the length of the extended end of the second cylinder 911, the precision casting is continuously cooled by clean water, thereby reducing the temperature inside the gate of the precision casting, preventing cracks from being generated when cutting the gate of the precision casting, avoiding deformation of the entire casting and generating burrs, thereby ensuring the quality of the product, and by forming a water wall when clean water flows on the inner wall of the water storage box 8, the generated sparks are shielded and cooled, which not only facilitates the collection of welding slag formed by cooling, but also avoids spark splashing to injure surrounding operators.

[0047] Step 1: Place the demoulded precision casting on the filter screen 6, and control the extended end of the second cylinder 911 to extend from half the length to the longest, so that the first piston 906 is separated from the output end of the water inlet pipe 908, and the first piston 906 blocks the input end of the water spray pipe 910, so that the clean water injected into the regulating cylinder 907 through the water inlet pipe 908 is injected into the water storage box 8 through the water outlet hole 905. At this time, the control valve is in a closed state, so that clean water accumulates in the water storage box 8. When the liquid level of the clean water in the water storage box 8 reaches the threshold, the extended end of the second cylinder 911 is promptly controlled to shrink and reset, and the output end of the water inlet pipe 908 is blocked by the first piston 906. At this time, the liquid level of the clean water immerses the bottom of the precision casting, and the precision casting is continuously cooled by the clean water, thereby reducing the temperature inside the gate of the precision casting, preventing cracks from being generated when cutting the gate of the precision casting, avoiding deformation of the entire casting and generating burrs, and ensuring the quality of its products;

[0048] Step 2: Then control the extended end of the first cylinder 1 to slowly extend, so that the moving platform 3 descends, and then open the cutting tool 2 to cut the gate of the precision casting. At the same time, control the extended end of the second cylinder 911 to shrink to the shortest, cooperate with the first lever 909 to drive the flip frame 903 to rotate, and clamp the precision casting with the pressing block 902 and the filter screen 6 to prevent the precision casting from shifting. At this time, the water outlet 905 is blocked by the first piston 906, so that clean water is injected into the water spray pipe 910, and then sprayed to the front side of the inner wall of the water storage box 8 through a plurality of water spray holes 901. When the clean water flows on the inner wall of the water storage box 8, a water wall is formed to shield and cool the generated sparks, which is not only convenient for collecting the welding slag formed by cooling, but also prevents sparks from splashing and injuring the surrounding operators.

[0049] Step 3: When the gate of the precision casting is cut by the cutting tool 2, the air pump 42 is turned on, and the harmful gas generated is absorbed into the filter box 41 through the L-shaped suction pipe 49 and the suction head to prevent it from affecting the health of the surrounding operators. At this time, the clean water in the water storage box 8 will push up the floating box 485, so that the lifting rod 486 drives the second piston 47 to block the output end of the first suction pipe 46, so as to prevent the clean water in the water storage box 8 from being sucked into the drying box 43;

[0050] Step 4: After cutting the gate of the precision casting, open the control valve and cooperate with the drain pipe 5 to drain the sewage carrying welding slag in the water storage box 8. When the sewage in the water storage box 8 is drained, the floating box 485 drives the lifting rod 486 to descend due to the influence of gravity, which not only drives the second piston 47 to separate from the output end of the first suction pipe 46 and the input end of the second suction pipe 44, but also cooperates with the second lever 481 to drive the sealing cover 487 to block the suction head. The air pump 42 drains the air in the drying box 43, so that the first suction pipe 46 draws out the air under the display table 7, thereby accelerating the air flow rate under the filter 6, which is convenient for accelerating the drying of the surface of the precision casting.
