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.

[0020] In the embodiment, the screw fixing assembly 8 includes two mounting plates 81 symmetrically fixedly connected to the side walls of the top end of the mounting ring 74, the inner walls of the mounting plates 81 are fixedly connected with fourth electric slide rails 82, the side walls of the fourth electric slide rails 82 are slidably connected with fourth slide plates 83, the side walls of the fourth slide plates 83 are fixedly connected with fourth electric telescopic rods 84, the telescopic ends of the fourth electric telescopic rods 84 are fixedly connected with side plates 85, and the inner walls of the side plates 85 are fixedly connected with fifth electric slide rails 86; The side walls of the fifth electric slide rail 86 are slidably connected to multiple fifth slides 87, the side walls of the multiple fifth slides 87 are fixedly connected to the third motor 88, the output ends of the third motor 88 are fixedly connected to the fifth electric telescopic rod 89, and the telescopic ends of the fifth electric telescopic rod 89 are fixedly connected to the clamping plate 810.

[0021] Specifically, the positions and inclination angles of multiple clamping plates 810 can be adjusted according to the pitch and inclination angle of the thread at the bolt support screw, so that the bolt support screw can be fixed by the clamping plates 810, and the bolt support can be driven by the clamping plates 810 to move so that the first drill bit 79 can clean and drill the molding sand at the bottom of the bolt support, thereby realizing the automatic cleaning and recovery of the molding sand outside the bolt support.

[0022] The operating principle of the present invention is now described as follows: In the present invention, when it is necessary to recover the molding sand outside the bolt support, the first electric slide rail 4 is first controlled to start, driving the first slide plate 5 to move upward, so that the fixed cylinder 63 moves to the uppermost end, and then the staff places the bolt support with the molding sand mold after casting on the placement plate 65, and then controls 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, and then controls the second electric telescopic rod 67 to start, driving the fixed plate 68 to move, and using the fixed plate 68 to simply fix the bolt support with the molding sand mold, and then controls the second electric slide rail 72 to start, driving 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, and then controls the second motor 7 7 and the third electric telescopic rod 78 are started, driving the first drill bit 79 to move to the outside of the sand mold while rotating the first drill bit 79, and using the first drill bit 79 to clean the sand outside the bolt support. In this process, the third electric slide rail 75 is controlled to start, driving the third slide plate 76 to rotate, so that the first drill bit 79 can clean the sand outside the screw rod of the bolt support. When the third electric telescopic rod 78 controls the first drill bit 79 to continuously approach the bolt support so that the screw rod of the bolt support is exposed, the extension of the third electric telescopic rod 78 is stopped, and then the third electric telescopic rod 78 is controlled to return to its original position, and then the second electric slide rail 72 is controlled to start, and the second slide plate 73 is used to drive the first drill bit 79 to continue to move downward. By controlling the above components to start, the first drill bit 79 is driven to move downward. The drill bit 79 cleans the molding sand at other places on the outer wall of the screw rod of the screw support. After the screw rod of the bolt support is completely exposed, the first drill bit 79 is controlled to return to its original position. During the movement of the third slide plate 76, the sixth slide plate 91 and the seventh slide plate 910 are both controlled to move by the third electric slide rail 75 to ensure that the sixth slide plate 91 and the seventh slide plate 910 do not affect the movement of the third slide plate 76. Then, the third electric telescopic rod 78 is controlled to start, so that the first drill bit 79 is inserted into the thread on the outer side of the screw rod of the bolt support, and then the first drill bit 79 is controlled to start to clean the molding sand in the thread. During this process, the third electric slide rail 75 and the second electric slide rail 72 are controlled to start, so that the first drill bit 79 moves upward while the bolt support rotates, so that the first drill bit 79 The moving trajectory is the same as the trajectory of the outer thread of the bolt support, which is convenient for using the first drill bit 79 to clean the molding sand in the outer thread of the bolt support screw. After the first drill bit 79 completes the cleaning of the molding sand in the screw thread, the mounting ring 74 is controlled to move to the lowermost end, and then the fourth electric slide rail 82 is controlled to start, driving the fourth slide plate 83 to move, so that the side plate 85 moves to the upper end of the outer wall of the bolt support screw, and then the fourth electric telescopic rod 84 is controlled to start, driving the side plate 85 to move, so that the card plate 810 approaches the outside of the screw, and then the fifth electric slide rail 86 is controlled to start, driving multiple fifth slide plates 87 to move, so that the distance between the multiple card plates 810 is the same as the spacing between the outer threads of the screw, and then the third motor 88 is controlled to start, driving the card plate 810 to rotate,The inclination angle of the clamping plate 810 is made the same as that of the outer thread of the screw rod, and then the fifth electric telescopic rod 89 is controlled to start, so that the clamping plate 810 moves to the inside of the thread and fits with the outer wall of the screw rod. At this time, the upper and lower side walls of the clamping plate 810 are in contact with the inner wall of the thread, so that the screw of the bolt support is fixed by multiple clamping plates 810, and then the fixing plate 68 is not fixed to the sand mold, and then the fourth electric slide rail 82 is controlled to start, driving the bolt support to move to the top of the placement plate 65, and then the first electric telescopic rod 64 is controlled to start, so that the placement plate 65 is flush with the upper side wall of the fixing tube 63, and then the second electric slide rail 72 is controlled 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, the fourth electric slide rail 82 is controlled to drive the fourth slide plate 83 to move upward, so that the bolt support always maintains the same position in the recovery tube 1, and then the first drill bit 79 is used to clean the molding sand outside the bottom of the bolt support, so that the bolt support is completely exposed. During this process, the fourth electric slide rail 82 is used to keep the bolt support always in the same position, so that the molding sand outside the bolt support can be cleaned with the first drill bit 79. Then the third electric slide rail 75 is controlled to start, drive the sixth slide plate 91 to move, and move the second drill bit 97 to one side of the screw hole at the bottom of the bolt support. Then the sixth electric telescopic rod 92 is controlled to start, so that the second drill bit 97 is located just above the screw hole at the bottom of the bolt support. Then the seventh electric telescopic rod 92 is controlled to start. The first motor 95 and the fourth motor 94 are started, and the second drill bit 97 is used to clean the molding sand in the screw hole at the bottom of the bolt support. Then, the eighth electric telescopic rod 98 is controlled to start, and the third drill bit 99 is driven to move toward the thread in the screw hole at the bottom of the bolt support, so that the third drill bit 99 is inserted into the thread in the screw hole at the bottom of the bolt support. Then, the seventh electric telescopic rod 95, the sixth motor 922 and the fourth motor 94 are controlled to start at the same time, so that the third drill bit 99 moves along the trajectory of the inner thread of the screw hole at the bottom of the bolt support, so that the molding sand in the inner side thread of the screw hole at the bottom of the bolt support is cleaned by the third drill bit 99. After the molding sand in the screw hole at the bottom of the bolt support is cleaned, the molding sand in other bottom screw holes is cleaned according to the above steps, and then the seventh electric telescopic rod 95, the sixth motor 922 and the fourth motor 94 are controlled to start at the same time, so that the third drill bit 99 moves along the trajectory of the inner thread of the screw hole at the bottom of the bolt support. The third electric slide 75 is started, driving the seventh slide 910 to move, so that the fourth drill bit 921 moves to one side of one of the bottom openings of the bolt support, and then the ninth electric telescopic rod 911 is controlled to start, so that the fourth drill bit 921 moves to the top of the corresponding bottom opening, and then the tenth electric telescopic rod 920 and the fifth motor 919 are controlled to start, so that the fourth drill bit 921 is inserted into the molding sand in the bottom opening of the bolt support to clean the molding sand in the bottom opening, and then the sixth electric slide 914 and the seventh electric slide 917 are controlled to start, driving the corresponding eighth slide 915 and the ninth slide 918 to move, so that the fourth drill bit 921 can clean the molding sand at other positions of the bottom opening. After completing the cleaning of the molding 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.
