Description

Technical Field

[0001] The invention belongs to the technical field of molding sand recovery, and in particular relates to a foundry molding sand recovery device. Background Art

[0002] Sand casting is the process of pressing the molding sand into a specific mold cavity, pouring liquid casting material into the mold cavity until it cools and solidifies to form a casting, and then separating the molding sand and the casting. After the molding sand is separated, it can be subsequently recycled and reused.

[0003] When using molding sand to cast the bolt support, in order to recycle and reuse the used molding sand, the staff usually uses a knocking hammer to knock the molding sand mold to make the molding sand on the outside of the bolt support fall off the surface of the bolt support. However, when the staff uses the knocking hammer to knock the molding sand mold, the knocking hammer is easy to damage the surface of the bolt support, affecting the quality of the bolt support after casting. In addition, when the molding sand mold is simply knocked with a knocking hammer, the molding sand on the thread outer wall of the bolt support screw and the thread inner thread of the screw hole opened in the bottom disk of the bolt support is difficult to clean out. After the staff cleans most of the molding sand on the outside of the bolt support, the molding sand mixed in the thread cannot be directly cleaned. At this time, the staff will use water to directly flush the molding sand mixed in the thread, so that the molding sand is completely separated from the outside of the bolt support, but the molding sand washed away by water is difficult to be collected for recycling, resulting in waste of molding sand, greatly reducing the recovery efficiency and reliability of molding sand recycling.

[0037] The operating principle of the present invention is described as follows:

[0038] In the present invention, when it is necessary to recycle the molding sand outside the bolt support, first, control the first electric slide rail 4 to start, drive the first slide plate 5 to move upward, so that the fixed cylinder 63 moves to the uppermost end. Then, the staff places the bolt support with the molding sand mold after casting above the placement plate 65. After that, control the first slide plate 5 to return to its original position, so that the bolt support with the molding sand mold enters the recovery cylinder 1. Then, control the second electric telescopic rod 67 to start, drive the fixed plate 68 to move, and use the fixed plate 68 to simply fix the bolt support with the molding sand mold. Then, control the second electric slide rail 72 to start, drive the second slide plate 73 to move, so that the first drill bit 79 on one side of the mounting ring 74 is located at the uppermost end of the side wall of the molding sand mold. Then, control the second motor 77 and the third electric telescopic rod 78 to start, drive the first drill bit 79 to move outward from the molding sand mold while rotating the first drill bit 79, and use the first drill bit 79 to clean the molding sand outside the bolt support. During this process, control the third electric slide rail 75 to start, drive the third slide plate 76 to rotate, so that the first drill bit 79 can clean the molding sand outside the screw of the bolt support. When the third electric telescopic rod 78 controls the first drill bit 79 to continuously approach the bolt support and the screw of the bolt support is exposed, stop the extension of the third electric telescopic rod 78. Then, control the third electric telescopic rod 78 to return to its original position. Then, control the second electric slide rail 72 to start, and use the second slide plate 73 to drive the first drill bit 79 to continue to move downward. By controlling the above components to start, the first drill bit 79 cleans the molding sand at other places on the outer wall of the screw of the screw support. After the screw of the bolt support is completely exposed, control the first drill bit 79 to return to its original position. And during the movement of the third slide plate 76, the sixth slide plate 91 and the seventh slide plate 910 are both controlled by the third electric slide rail 75 to move, ensuring that the sixth slide plate 91 and the seventh slide plate 910 do not affect the movement of the third slide plate 76. Then, control the third electric telescopic rod 78 to start, so that the first drill bit 79 is inserted into the thread outside the screw of the bolt support. Then, control the first drill bit 79 to start, and clean the molding sand in the thread. During this process, control the third electric slide rail 75 and the second electric slide rail 72 to start, so that the first drill bit 79 moves upward while rotating around the bolt support, so that the movement track of the first drill bit 79 is the same as the thread track outside the bolt support, facilitating the use of the first drill bit 79 to clean the molding sand in the thread outside the screw of the bolt support. After the first drill bit 79 finishes cleaning the molding sand in the screw thread, control the mounting ring 74 to move to the lowermost end. Then, control the fourth electric slide rail 82 to start, drive the fourth slide plate 83 to move, so that the side plate 85 moves to the upper end of the outer wall of the screw of the bolt support. Then, control the fourth electric telescopic rod 84 to start, drive the side plate 85 to move, so that the clamping plate 810 approaches the outside of the screw. Then, control the fifth electric slide rail 86 to start, drive a plurality of fifth slide plates 87 to move, so that the distance between the plurality of clamping plates 810 is the same as the pitch between the threads outside the screw. Then, control the third motor 88 to start, drive the clamping plate 810 to rotate,Make the inclination angle of the clamping plate 810 the same as that of the outer thread of the screw rod. Then, control the fifth electric telescopic rod 89 to start, so that the clamping plate 810 moves into the thread and fits against the outer wall of the screw rod. At this time, both the upper and lower side walls of the clamping plate 810 are in contact with the inner wall of the thread, thereby fixing the screw rod of the bolt support using multiple clamping plates 810. Then, make the fixing plate 68 not fix the sand mold. Then, control the fourth electric slide rail 82 to start, driving the bolt support to move above the placement plate 65. Then, control the first electric telescopic rod 64 to start, making the placement plate 65 flush with the upper side wall of the fixed cylinder 63. Then, control the second electric slide rail 72 to drive the mounting ring 74 to move downward, so that the first drill bit 79 moves to the lowermost end of the outer wall of the sand mold. During this process, control the fourth electric slide rail 82 to drive the fourth slide plate 83 to move upward, so that the bolt support always maintains the same position within the recovery cylinder 1. Then, use the first drill bit 79 to clean the sand outside the bottom of the bolt support, making the bolt support completely exposed. During this process, use the fourth electric slide rail 82 to keep the bolt support in the same position all the time, which is convenient for using the first drill bit 79 to clean the sand outside the bolt support. Then, control the third electric slide rail 75 to start, driving the sixth slide plate 91 to move, so that the second drill bit 97 moves to one side of the bottom screw hole of the bolt support. Then, control the sixth electric telescopic rod 92 to start, making the second drill bit 97 located directly above the bottom screw hole of the bolt support. Then, control the seventh electric telescopic rod 95 and the fourth motor 94 to start, using the second drill bit 97 to clean the sand in the bottom screw hole of the bolt support. Then, control the eighth electric telescopic rod 98 to start, driving the third drill bit 99 to move towards the thread in the bottom screw hole of the bolt support, so that the third drill bit 99 inserts into the thread in the bottom screw hole of the bolt support. Then, control the seventh electric telescopic rod 95, the sixth motor 922, and the fourth motor 94 to start simultaneously, so that the third drill bit 99 moves along the track of the thread in the bottom screw hole of the bolt support, thereby using the third drill bit 99 to clean the sand in the inner thread of the bottom screw hole of the bolt support. After completing the cleaning of the sand in the bottom screw hole of this bolt support, clean the sand in other bottom screw holes according to the above steps. Then, control the third electric slide rail 75 to start, driving the seventh slide plate 910 to move, so that the fourth drill bit 921 moves to one side of one of the bottom openings of the bolt support. Then, control the ninth electric telescopic rod 911 to start, making the fourth drill bit 921 move above the corresponding bottom opening. Then, control the tenth electric telescopic rod 920 and the fifth motor 919 to start, so that the fourth drill bit 921 inserts into the sand in the bottom opening of the bolt support to clean the sand in the bottom opening. Then, by controlling the sixth electric slide rail 914 and the seventh electric slide rail 917 to start, driving the corresponding eighth slide plate 915 and ninth slide plate 918 to move, so that the fourth drill bit 921 can clean the sand at other positions of the bottom opening. After completing the cleaning of the sand here,According to the above steps, the molding sand at other bottom openings is cleaned (during the movement of the sixth slide 91, the seventh slide 910 and the third slide 76, the other two corresponding slides follow the movement to ensure that the other two corresponding slides do not affect the movement of the working slide). At this time, the molding sand outside the bolt support is cleaned. The cleaned molding sand will fall to the bottom of the recovery cylinder 1 and above the placement plate 65. At this time, the first motor 61 is controlled to start, driving the fixed cylinder 63 and the placement plate 65 to rotate, so that the molding sand above the placement plate 65 falls to the bottom of the recovery cylinder 1. Then the solenoid valve 10 is controlled to open, and the recovered molding sand can be collected and utilized. When the drill bit cleans the molding sand from the bolt support, the drill bit will drill the molding sand into pieces. At this time, the molding sand will be in powder form, which is convenient for direct recycling of the molding sand. There is no need to put the cleaned molding sand into a crusher for crushing. When the molding sand outside the bolt support needs to be recycled, the first drill bit 79 can be used to crush the molding sand in the thread of the screw rod of the bolt support. The sand can be cleaned and drilled, and the second drill bit 97, the third drill bit 99 and the fourth drill bit 921 can be used to clean and drill the molding sand in the thread of the screw hole at the bottom of the bolt support and the molding sand in the bottom opening of the bolt support, so as to facilitate the recycling of the molding sand outside the bolt support. The positions and inclination angles of the multiple clamping plates 810 can be adjusted according to the pitch and inclination angle of the thread at the screw rod of the bolt support, so as to facilitate the use of the clamping plates 810 to fix the screw rod of the bolt support, so as to facilitate the clamping plates 810 to drive the bolt support to move so that the first drill bit 79 can clean and drill the molding sand at the bottom of the bolt support, so as to realize the automatic cleaning and recycling of the molding sand outside the bolt support, so as to avoid the staff from damaging the surface of the bolt support with the hammer when they use the hammer to knock the sand mold, thereby affecting the quality of the bolt support after casting, and at the same time, avoid the staff from using water to wash the molding sand mixed in the thread, resulting in the waste of molding sand, and greatly improve the recycling efficiency and reliability of the molding sand recycling.
