Technical Field

[0001] This utility model belongs to the technical field of the foundry industry, specifically relating to a dual-station box lowering and moving machine. Background Technology

[0002] The static pressure molding line is an automated production line used in the foundry industry for mass production of high-precision sand molds. The core of the line is the "static pressure molding method" to prepare the sand mold. It integrates sand material processing, molding, core setting, drilling and milling, mold assembly, and pouring preparation into a continuous process. The typical configuration is dual main machine working in tandem, which can efficiently complete the synchronous manufacturing of upper and lower sand molds and the connection of subsequent processes.

[0003] The existing equipment uses a single-line serial wiring. After the upper and lower boxes are separated by the box-separating machine, they still flow sequentially on the same side roller frame conveyor line. The lower core section and the upper box section need to be arranged in the order of the process. In order to meet the layout requirements of multi-station core lowering and drilling and milling equipment, it can only be achieved by extending the length of the conveyor line, which leads to a significant increase in the space occupied by the entire line. It has strict requirements on the length of the molding workshop, and layout constraints are likely to occur, especially in small and medium-sized workshops.

[0004] Therefore, this utility model provides a dual-station box lowering and moving machine. Utility Model Content

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-6This utility model provides a dual-station box lowering and moving machine, including a support frame 1, a support frame 2 fixedly connected to the rear end of the support frame 1, a support frame 3 fixedly connected to the rear end of the support frame 2, a support rod 4 fixedly connected to the left side inside the support frame 3, and a plurality of support rollers 5 arranged in a linear array rotatably connected to the top of the support rod 4. The entire box is moved into the interior of the support frame 3 via the support rollers 5. A hydraulic cylinder 6 is fixedly installed on the top of the support frame 3, and a rectangular frame 7 is fixedly connected to the telescopic end of the hydraulic cylinder 6. An upper box gripper 8 is installed at the bottom of the rectangular frame 7, which grips the upper part of the entire box. A support rod 9 is fixedly installed on the right side inside the support frame 3, and a plurality of support rollers 10 arranged in a linear array are rotatably connected to the top of the support rod 9. The support rollers 10 are used to support and transport the upper box. A hydraulic cylinder 11 is fixedly installed at the rear end of the support frame 3 via a support frame 4. A push block 12 is fixedly installed at the telescopic end of support frame 1. Hydraulic cylinder 2 11 drives push block 12 to push the upper box, so that the upper box moves to the next operation via support roller 2 10. Hydraulic cylinder 3 13 is fixedly installed on the top of support frame 1. A buffer frame 14 is fixedly connected to the telescopic end of hydraulic cylinder 3 13. The buffer frame 14 is at the same height as the lower box transported by support roller 5, and can buffer the moving lower box. A lower box gripper 15 is installed on the top of support frame 2. The lower box gripper 15 is used to grab the remaining lower box, so that the lower box can enter the next operation. Rectangular frame 1 7 is slidably connected to the top of support frame 3. By sliding rectangular frame 1 7 on the top of support frame 3, the upper box gripper 8 is moved, so that after the upper box gripper 8 grabs the upper box, it can move the upper box to the upper part of support roller 2 10. Buffer frame 14 is slidably connected to the top of support frame 1. One end of support rod 4 extends into the interior of support frame 2.

[0018] In use, the stacking of the upper and lower boxes of this invention begins by allowing the upper and lower boxes to enter the interior of the support frame 3 via the support rollers 5 on the support rod 4. Then, the hydraulic cylinder 6 drives the rectangular frame 7 to slide inside the support frame 3 until the upper box gripper 8 is directly above the entire box and grips it. The hydraulic cylinder 6 then drives the rectangular frame 7 to reset the upper box gripper 8, placing the upper box on the support rollers 10 on the support rod 9. The hydraulic cylinder 11 then drives the push block 12, pushing the upper box to the next step. The remaining lower box is then pushed by external equipment into the lower box gripper 15, positioned above the support rollers 15010. The hydraulic cylinder 13 and the buffer frame 14 provide cushioning and limiting for the lower box. The lower box gripper 15 then lowers the lower box until it reaches a suitable position, at which point it is released and placed on the transport equipment, completing the transfer of the lower box.

[0019] This invention effectively achieves synchronous separation and independent, efficient conveying of the upper and lower boxes, which shortens the overall line length, reduces workshop space requirements, reduces pushing time, increases core setting and drilling / milling operation time, avoids collision damage during sand box conveying, improves sand mold quality and production cycle time, and provides adaptability for the design of subsequent higher-speed static pressure molding lines, meeting the needs of flexible arrangement of multi-station core setting and drilling / milling equipment.

[0020] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the upper box gripper 8 includes a hydraulic cylinder 807 fixedly installed on the upper end of a rectangular frame 7. The telescopic end of the hydraulic cylinder 807 passes through the bottom of the rectangular frame 7 and is fixedly connected to a support frame 801. The two sides of the support frame 801 are rotatably connected to gripping hooks 802, which are L-shaped. A connecting block 803 is fixedly connected to one side of the two gripping hooks 802 that are close to each other. A hydraulic cylinder 804 is rotatably connected to the side of one connecting block 803. The telescopic end of the hydraulic cylinder 804 is rotatably connected to the other connecting block 803. A linkage rod 805 is rotatably connected between the two connecting blocks 803 and below the hydraulic cylinder 804. The linkage rod 805 is distributed in an inclined manner. A support block 806 is fixedly connected to the side of the bottom of the two gripping hooks 802. The support block 806 can contact the surface of the upper box and play a protective role for the upper box. When using the upper box gripper 8, firstly, hydraulic cylinder 4 807 is activated to drive the rectangular frame 7 to descend, so that the gripping hooks 802 on both sides of the rectangular frame 7 are located on the side of the upper box. Then, hydraulic cylinder 6 804 is activated, so that hydraulic cylinder 6 804, together with linkage rod 805, pulls the connecting blocks 803 rotatably connected to both ends, thereby driving the gripping hooks 802 to work with the support block 806 to clamp the upper box. Then, hydraulic cylinder 4 807 is activated again to drive the support frame 801 to rise.

[0021] Specifically, such as Figure 1 , Figure 5 and Figure 6As shown, the lower box gripper 15 includes a hydraulic cylinder 1501 fixedly installed on the top of the support frame 2. The telescopic end of the hydraulic cylinder 1501 passes through the support frame 2 and is fixedly connected to the support frame 2 1502. Grip hooks 1503 are rotatably connected to both sides of the support frame 2 1502. Connecting blocks 1504 are fixedly connected to the sides of the tops of the grip hooks 1503 that are close to each other. A hydraulic cylinder 1505 is rotatably connected between the connecting blocks 1504. Below 5 and between connecting blocks 1504, a linkage rod 1506 is rotatably connected. On the opposite sides of the two grab hooks 1503, cylinders 1509 are rotatably connected. The telescopic end of cylinder 1509 is rotatably connected to a U-shaped block 1507. One end of U-shaped block 1507 is rotatably connected to grab hook 1503, and the other end is rotatably connected to a support plate 1508. On the side of support plate 1508 away from U-shaped block 1507, a support roller 15010 is rotatably connected. When the lower box gripper 15 is working, firstly, hydraulic cylinder five 1501 is activated, causing hydraulic cylinder five 1501 to drive support frame two 2 to descend. When support frame two 2 descends to the appropriate position, firstly, cylinder one 1509 is activated, causing cylinder one 1509 to pull support plate 1508 through U-shaped block 1507 at the telescopic end. This causes support roller three 15010 located at the bottom of the lower box to separate from the bottom of the lower box as support plate 1508 moves. Then, hydraulic cylinder seven 1505 is activated in conjunction with linkage rod two 1506 to separate the two gripping hooks two 1503 on both sides, thus completing the movement of the lower box. Finally, hydraulic cylinder five 1501 is activated to drive support frame two 1502 to rise, and the operation can be repeated.

[0022] Working principle and usage process of this utility model: When operating the dual-station box lowering and moving machine, the operator first ensures that the stacked upper and lower boxes are smoothly moved into the support frame 3 via the support rollers 5. Next, the hydraulic cylinder 6 at the top of the support frame 3 is activated, driving the rectangular frame 7 to move until the upper box gripper 8 at the bottom of the rectangular frame 7 is directly above the box. Then, the hydraulic cylinder 807, fixed to the upper end of the rectangular frame 7 in the upper box gripper 8, is activated. Its telescopic end penetrates the bottom of the rectangular frame 7 and lowers the support frame 801, causing the L-shaped hooks 802 rotatably connected to both sides of the support frame 801 to descend. With the upper box aligned with the side, the hydraulic cylinder 804, which is rotatably connected to the side of one connecting block 803, is activated. The telescopic end of the hydraulic cylinder 804, in conjunction with the inclined linkage rod 805 between the two connecting blocks 803, pulls the two connecting blocks 803, allowing the grab hook 802 to securely clamp the upper box with the support block 806 fixed to its bottom side. Then, the hydraulic cylinder 807 drives the support frame 801 to rise, and the hydraulic cylinder 6 drives the rectangular frame 7 to reset, placing the upper box on the support roller 210 at the top of the right support rod 29 inside the support frame 3. At this time, the support is activated. Hydraulic cylinder 2 11, fixed to the rear end of support frame 3 via support frame 4, pushes the upper box to the next operation by its telescopic end driving push block 12. For the remaining lower box, the operator uses external equipment to push it to continue moving, so that it enters the lower box gripper 15 installed on the top of support frame 2 2 and is positioned above support roller 3 15010. During this process, the buffer frame 14 connected to the telescopic end of hydraulic cylinder 3 13 on the top of support frame 1 1 acts as a buffer and limiter for the lower box. Then, hydraulic cylinder 5 1501 in the lower box gripper 15 is activated, and its telescopic end drives support frame 2 15. 02. Once the container has descended to the appropriate position, first activate cylinder 1509, which is rotatably connected to the opposite side of hook 2 1503. The telescopic end of cylinder 1509 pulls support plate 1508 through U-shaped block 1507, causing support roller 3 15010, which is rotatably connected to the side of support plate 1508 away from U-shaped block 1507, to separate from the bottom of the lower box. Then, activate hydraulic cylinder 7 1505, which is rotatably connected between connecting blocks 2 1504, and work with linkage rod 2 1506 below it to separate hooks 2 1503 on both sides, so that the lower box can be placed stably on the transport equipment, completing the transfer of the lower box.
