Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for static pressure molding line production, in particular to a sleeve box moving mechanism. Background Art

[0002] In the existing static pressure molding production line, a trolley usually carries a sand box and moves back and forth on a rotary line. After reaching the designated position, the casting in the sand box is taken out. Since different castings have different requirements for cooling time, for castings with a large temperature drop, the sand box alone cannot meet the cooling needs by moving on the rotary line. In order to solve the above problem, a sleeve box that can hold molding sand is introduced. The molding sand in the sand box is transferred to the sleeve box, and the sleeve box is also allowed to move back and forth on another rotary line for cooling. After cooling, the sleeve box containing molding sand needs to be moved to the designated position and the casting inside is taken out. The existing equipment currently uses a gantry and an openable and closable grabbing robot to achieve the movement of the sleeve box. However, the gantry setting takes up a lot of space, and the grabbing robot is prone to shaking when transferring the sleeve box, which to a certain extent affects the quality of the molding sand and castings inside.

[0013] The utility model is a case moving mechanism, such as Figure 1-3 As shown, it includes a stand 1, a horizontally arranged walking chute 2 is provided on the inner side of the stand 1, and a movable casing grabbing walking device is installed in the walking chute 2. The casing grabbing walking device can clamp and grab the casing and move it to a designated position to perform the casting removal operation.

[0014] The box grabbing walking device includes a walking frame 3. The walking frame 3 serves as the load-bearing body of the device and can be composed of a frame structure, which can ensure sufficient load-bearing performance and effectively reduce the weight of the entire device. To achieve the movement of the device, both sides of the walking frame 3 are equipped with walking wheels 4 that cooperate with the walking chute 2. A walking motor 5 is installed at one end of the walking frame 3 in the longitudinal direction. A gear 6 is installed on the output shaft of the walking motor 5. A rack 7 that meshes with the gear 6 is installed on the frame 1. When the walking motor 5 is started, the walking frame 3 can move within the walking chute 2.

[0015] In order to achieve a firm clamping and grasping of the casing, connecting frames 8 are installed at the bottom of both ends of the walking frame 3 in the length direction. Two groups of limiting wheels 9 arranged side by side are provided on the inner side of each connecting frame 8. The limiting wheels 9 can clamp and limit the protrusions on both sides of the casing. A positioning cylinder 10 is also installed on the outer side of the connecting frame 8. The piston rod of the positioning cylinder 10 can extend between the two groups of limiting wheels 9 on the inner side of the connecting frame 8. A positioning hole that matches the positioning cylinder 10 is also provided on the side of the casing. While the limiting wheels 9 clamp the casing, the positioning cylinder 10 can also insert and position the casing, thereby achieving horizontal, vertical and vertical axial limitation of the casing, ensuring the stability of the moving process, and ensuring the quality of the castings inside the molding sand.

[0016] Furthermore, in order to increase the driving force of the entire device, the movement of multiple sets of boxes can be realized, such as Figure 4As shown, two groups of walking motors 5 arranged side by side are installed at one end of the walking frame 3 in the length direction, and a gear 6 is installed on the output shaft of each walking motor 5. Two rows of horizontally arranged racks 7 are installed on the vertical frame 1, and the racks 7 are respectively engaged with the gears 6 on their respective sides.

[0017] Furthermore, in order to achieve the stability of the device when driving the casing to move, as Figure 6 As shown, first guide wheels 11 are installed at both ends of the walking frame 3 in the length direction, and pads 12 in contact with the first guide wheels 11 are installed on the inner side of the walking chute 2. The arrangement of the pads 12 on both sides and the first guide wheels 11 can effectively prevent the walking frame 3 from shaking during movement.

[0018] Furthermore, a horizontally arranged motor frame 13 is installed at one end of the walking frame 3 in the length direction, and the walking motor 5 is arranged on the motor frame 13. A horizontally arranged second guide wheel 14 is also installed on the motor frame 13, and the rack 7 is located between the second guide wheel 14 and the gear 6. The setting of the second guide wheel 14 can keep the rack 7 and the gear 6 always engaged, ensuring power input during the movement.

[0019] Furthermore, in order to prevent sand from falling into the walking chute 2 and affecting the normal movement of the device during the transfer of molding sand, a first sand scraper 15 is installed on the walking frame 3 on both sides of the walking wheel 4. When the walking wheel 4 moves in the walking chute 2, the first sand scraper 15 can clean the sand in the walking chute 2 to ensure the stability of the device's movement.

[0020] In order to realize the processing of sand falling from the bottom of the casing during the reciprocating movement of the device, Figure 5 As shown, a connecting plate 16 is fixedly installed at the bottom of the connecting frame 8, and a second sand scraping plate 17 is provided on the outer side of the bottom of the connecting plate 16, wherein the second sand scraping plate 17 is provided with a plurality of elongated holes 18 arranged side by side, and connecting bolts 19 are installed in the elongated holes 18. A threaded hole that cooperates with the connecting bolts 19 is provided at the bottom of the connecting frame 8. When the connecting bolts 19 are loosened, the length of the second sand scraping plate 17 extending out of the connecting plate 16 can be adjusted, that is, the height position of the second sand scraping plate 17 can be adjusted to adapt to the falling sand cleaning at different heights on the opposing frame 1.
