Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, and in particular to a casting surface treatment device. Background Art

[0002] Silica sol castings are castings produced by the silica sol process. When casting some copper-iron alloy crafts with complex shapes or high-precision copper-iron alloy mechanical parts, the silica sol casting process can ensure that the copper-iron alloy solution can completely fill every detail of the mold, thereby producing copper-iron castings that meet the requirements; it has very high dimensional accuracy and surface finish, which can reduce mechanical processing work, and only leaves a small amount of processing allowance on the parts with higher requirements. Some castings even only leave grinding and polishing allowances and can be used without mechanical processing; silica sol castings have a smooth and flat surface, bright color, no bubbles, firm and tight, exquisite workmanship, easy to use and install.

[0031] When the debris slides into the collection box 51 from the discharge port, the electromagnet 52 is used to absorb large metal debris, and the non-metallic debris and some small debris fall below with the air flow. At the same time, the electromagnet 52 absorbs the magnetic end 531 of the collection plate 53, so that the two collection plates 53 are connected to each other and are in a closed state.

[0032] A rotating plate 54 is arranged below the abutting end 532 of the collecting plate 53, and the rotating plate 54 is rotatably installed in the collecting box 51, and the abutting end 532 abuts against the rotating plate 54, and the rotating shaft of the rotating plate 54 is located on the side close to the magnetic end 531 of the collecting plate 53; a filter chamber 55 is arranged at the end of the rotating plate 54 away from the collecting plate 53, and an inlet is opened at the end of the filter chamber 55 close to the rotating plate 54; a feed baffle 551 is rotatably installed on the feed inlet, and the rotating shaft of the feed baffle 551 is located at the top of the feed inlet; a connecting piece 541 is rotatably installed on the rotating plate 54, and the connecting piece 541 is hinged to the feed baffle 551; a rotation gap is left between the bottom of the feed inlet and the rotating plate 54; a spring 557 is arranged in the rotation gap, and the two ends of the spring 557 are respectively connected to the filter chamber 55 and the rotating plate 54.

During the downward swinging of the rotating plate 54, the feed baffle 551 is driven to swing through the connecting piece 541 to open the feed port. At this time, non-metallic debris and small-particle metal debris slide from the rotating plate 54 into the filter chamber 55; during the downward swinging of the rotating plate 54, the end in contact with the collecting plate 53 drives the collecting plate 53 to swing, so that a downward flow gap is formed between the two collecting plates 53, so that the large-particle metal debris that slides from the electromagnet 52 to the collecting plate 53 falls from the flow gap.

[0034] A nozzle 552 is also installed inside the filter chamber 55, and the liquid outlet end of the pump body 42 is also connected to the filter chamber 55 through a pipeline; a capsule 553 and a micro switch 554 are also installed on the top of the inside of the filter chamber 55; the air outlet end of the capsule 553 is connected to a piston tube 555, and a piston 556 is slidably installed in the piston tube 555, and the piston 556 is connected to the nozzle 552; when the feed baffle 551 swings, it squeezes the capsule 553, and then contacts the micro switch 554, and then the feed baffle 551 continues to squeeze the capsule 553, and the piston 556 slides under pressure, driving the nozzle 552 to swing; the nozzle 552 is connected to a solenoid valve, and when it contacts the micro switch 554, the solenoid valve opens to spray water.

[0035] As an optional solution, the nozzle in the filter chamber 55 can be eliminated, and an exhaust fan can be provided at the bottom of the filter chamber 55. When the micro switch 554 is triggered, the exhaust fan is started to exhaust air.

When the cleaning brush 61 is retracted, it contacts the serrated structure and cleans the cleaning brush 61. At this time, due to the action of the torsion spring, the cleaning brush 61 will not rotate upward or may rotate slightly upward, which will not affect the cleaning effect of the cleaning brush 61. Then, when the sliding rod 626 contacts the bottom of the slide groove, the piston rod drives the L-shaped rotating block 623 and the L-shaped limiting block 624 to rotate along the rotating axis of the L-shaped limiting block 624, thereby driving the cleaning brush 61 to rotate upward and away from the workbench.
