Description

Technical Field

[0001] This utility model relates to the field of casting cleaning technology, and in particular to a collection device for cleaning molding sand from the surface of castings. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and the mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings, and has long been a basic process in casting production.

[0003] After sand casting is completed, the surface molding sand needs to be effectively cleaned when the casting is removed. Common cleaning methods include water flushing or vibration to remove the molding sand. During the vibration process of removing surface molding sand, the shaken molding sand often accumulates on the clamping table surface, requiring workers to frequently clean the molding sand. Furthermore, the shaken molding sand is not properly collected and organized, and needs to be recycled later. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a collection device for cleaning molding sand from the surface of castings.

[0005] This utility model is achieved through the following technical solution:

[0006] A collection device for cleaning molding sand from the surface of castings includes a collection box, a support frame, a support mechanism, an equipment frame, a first hydraulic cylinder, a vibrating frame, a vibrator, a second hydraulic cylinder, and a pushing mechanism. The support frame is fixedly installed on the top of the collection box, the support mechanism is fixedly installed on the top of the support frame, the equipment frame is fixedly installed at the tail end of the support frame, the first hydraulic cylinder is fixedly installed on the top of the equipment frame, the vibrating frame is fixedly installed at the telescopic end of the first hydraulic cylinder, the vibrator is connected to the inner bottom of the vibrating frame, the second hydraulic cylinder is installed on the back of the equipment frame, and the pushing mechanism is located at one end of the collection box. The support mechanism includes a support base, a rotating shaft, a rotating disk, a guide rod, a connecting block, a retaining shaft, and a tilting seat. The support base is fixedly installed on the top of the support frame, the rotating shaft is fixedly connected to the support base, the rotating disk is movably connected to the top of the rotating shaft, the guide rod is retained on the side of the support base, the connecting block is fixed to the end of the guide rod, and the tilting seat is movably connected to the connecting block through the retaining shaft.

[0007] In a preferred embodiment of the present invention, the pushing mechanism includes an equipment compartment, a third hydraulic cylinder, a push plate, a flap plate, and a support bar. The equipment compartment is located on the outer side of one end of the collection box. The third hydraulic cylinder is installed on the outer side of the equipment compartment. The push plate is fixedly located on the telescopic end of the third hydraulic cylinder. The flap plate is movably connected to one side of the bottom of the push plate by a pin. The support bar is fixedly located on the bottom of the push plate.

[0008] The pushing mechanism mainly pushes the molding sand that has fallen into the collection box forward, thereby preventing the molding sand from accumulating at the bottom of the support mechanism and affecting the falling of the molding sand. It also provides sufficient space for the timely cleaning of the molding sand and facilitates subsequent cleaning work.

[0009] In a preferred embodiment of the present invention, the rotating disk is disposed at the bottom of the output end of the vibrator, and the top two ends of the support base are provided with mounting platforms that cooperate with the connecting block;

[0010] The first hydraulic cylinder descends, controlling the vibrator to descend as well, so that its output end presses well against the surface of the casting, controlling the vibration of the casting to shake off the surface molding sand.

[0011] In a preferred embodiment of this utility model, the top of the push plate is provided with an upwardly inclined guide surface, and the back of the flip plate is attached to one side of the support bar.

[0012] In a preferred embodiment of this utility model, after the extension end of the second hydraulic cylinder extends, its end contacts the inner side of the bottom of the collection box, thereby achieving the effect of support and improving stability.

[0013] In a preferred embodiment of this utility model, a limiting piece is fixedly provided at the end of the guide rod, and a guide insertion hole that mates with the guide rod is provided on the side of the support base;

[0014] The guide rod end limit plate prevents the connecting block from falling off the side of the support base. Moving the connecting block outward allows the material turning base to flip, providing space for the accumulated molding sand on the surface to fall off.

[0015] The beneficial effects of this utility model are:

[0016] The support mechanism of the sand collection device for cleaning the surface of the casting can be opened and flipped to quickly clean the sand that falls onto its surface. After the sand falls off, it enters the collection box and the area where the sand fell off is cleaned up in time, thereby avoiding the accumulation of sand and providing sufficient space for subsequent falling sand, and facilitating the collection and recycling of sand.

[0023] like Figure 1-4 The illustrated collection device for cleaning molding sand from the surface of castings includes a collection box 1, a support frame 2, a support mechanism 3, an equipment frame 4, a first hydraulic cylinder 5, a vibrating frame 6, a vibrator 7, a second hydraulic cylinder 8, and a pushing mechanism 9. The support frame 2 is fixedly mounted on the top of the collection box 1, the support mechanism 3 is fixedly mounted on the top of the support frame 2, the equipment frame 4 is fixedly mounted on the tail end of the support frame 2, the first hydraulic cylinder 5 is fixedly mounted on the top of the equipment frame 4, the vibrating frame 6 is fixedly mounted on the telescopic end of the first hydraulic cylinder 5, the vibrator 7 is connected to the inner bottom of the vibrating frame 6, and the second hydraulic cylinder 8... Installed on the back of the equipment frame 4, the pushing mechanism 9 is set at one end of the collection box 1. The support mechanism 3 includes a support base 31, a rotating shaft 32, a rotating disk 33, a guide rod 34, a connecting block 35, a retaining shaft 36, and a turning seat 37. The support base 31 is fixedly set on the top of the support frame 2. The rotating shaft 32 is fixedly connected to the support base 31. The rotating disk 33 is movably connected to the top of the rotating shaft 32. The guide rod 34 is clamped on the side of the support base 31. The connecting block 35 is fixed to the end of the guide rod 34. The turning seat 37 is movably connected to the connecting block 35 through the retaining shaft 36.

[0024] Specifically, the pushing mechanism 9 includes an equipment compartment 91, a third hydraulic cylinder 92, a push plate 93, a flap plate 94, and a support bar 95. The equipment compartment 91 is located on the outer side of one end of the collection box 1. The third hydraulic cylinder 92 is installed on the outer side of the equipment compartment 91. The push plate 93 is fixedly installed on the telescopic end of the third hydraulic cylinder 92. The flap plate 94 is movably connected to one side of the bottom of the push plate 93 by a pin. The support bar 95 is fixedly installed on the bottom of the push plate 93. The rotating disk 33 is located at the bottom of the output end of the vibrator 7. The top two ends of the support base 31 are provided with mounting platforms that cooperate with the connecting block 35. The top of the push plate 93 is provided with an inclined upward guide surface. The back of the flap plate 94 is attached to one side of the support bar 95. After the telescopic end of the second hydraulic cylinder 8 extends, its end contacts the inner side of the bottom of the collection box 1 to achieve support and improve stability. The end of the guide rod 34 is fixedly provided with a limit piece. The side of the support base 31 is provided with a guide insertion hole that cooperates with the guide rod 34.

[0025] In this embodiment, the extension end of the second hydraulic cylinder 8 is first extended so that its extension end contacts the bottom of the collection box 1, which provides a stable support effect. Then, the casting is placed on the surface of the rotating disk 33, and the first hydraulic cylinder 5 is controlled to extend so that the output end of the vibrator 7 installed in the bottom vibration frame 6 contacts the surface of the casting. After the vibrator 7 is turned on, the high-frequency vibration causes the molding sand on the surface of the casting to fall off. The molding sand will fall onto the surface of the turning seat 37 and into the collection box 1.

[0026] Furthermore, when it is necessary to clean the molding sand on the surface of the turning seat 37, simply pull out the connecting block 35. Under the guidance of the guide rod 34, the connecting block 35 moves outward. At this time, the turning seat 37 can be turned outward around the clamping shaft 36, so that the molding sand on its surface can fall into the collection box 1. At this time, the second hydraulic cylinder 8 retracts and the third hydraulic cylinder 92 extends, driving the push plate 93 to push forward. Under the limiting support of the support bar 95, the turning plate 94 cooperates with the push plate 93 to push the molding sand forward, away from the bottom of the support frame 2, providing space for subsequent molding sand to fall. The push plate 93, which is set at the top and tilted upward, has a certain material guiding effect, reducing the molding sand from falling behind the push plate 93. When the third hydraulic cylinder 92 retracts, the turning plate 94 will automatically flip up when it encounters the fallen molding sand, thereby preventing the molding sand from being brought into the equipment chamber 91, thus realizing the rapid cleaning of molding sand and facilitating the recycling of molding sand.
