[0023] like Figure 1-4As shown, the utility model provides an embodiment of a transfer tray for a large sand core, comprising a base 200, a first support seat 300 for abutting the first cross beam 110 of the sand core, and a second support seat 400 for abutting the second cross beam 120 of the sand core, the first support seat 300 and the second support seat 400 are fixedly arranged at both ends of the base 200 along the Y-axis direction, the first support seat 300 and the second support seat 400 are arranged opposite to each other, and the height of the first support seat 300 is lower than the height of the second support seat 400; the base 200 is provided with a first cavity 500 for accommodating the first longitudinal beam 130 of the sand core and a second cavity 600 for accommodating the second longitudinal beam 140 of the sand core, the first cavity 500 and the second cavity 600 are respectively located near the two ends of the base 200 along the X-axis direction, and the first cavity 500 and the second cavity 600 are symmetrically arranged. Among them, the base 200, the first support seat 300 and the second support seat 400 are preferably prepared by plastic wood material.
[0024] When in use, the large sand core to be transported is placed on the base 200, so that the bottom of the first crossbeam 110 of the sand core abuts against the first support seat 300, the bottom of the second crossbeam 120 of the sand core abuts against the second support seat 400, the first longitudinal beam 130 of the sand core is located in the first cavity, and the second longitudinal beam 140 of the sand core is located in the second cavity. Then, the transport pallet is transferred to the predetermined position by the transport equipment, which can reduce the collision of the relatively thin structure of the sand core during the transportation process, thereby reducing the damage rate of the sand core and reducing costs.
[0025] Furthermore, if Figure 2-3 As shown, the first support seat 300 includes a first support block 310 and a second support block 320, and the first support block 310 and the second support block 320 are distributed on the base 200 along the Y-axis direction, and the tops of the first support block 310 and the second support block 320 can be fitted with the bottom of the first crossbeam 110 of the sand core.
[0026] Specifically, the first support block 310 and the second support block 320 support the first cross beam 110 of the sand core to prevent the local thin structure on the first cross beam 110 of the sand core from directly contacting the base 200, thereby reducing the collision rate of the first cross beam 110 during the transportation of the sand core.
[0027] Furthermore, if Figure 2-3 As shown, the second support seat 400 includes a third support block 410, a fourth support block 420 and a fifth support block 430. The fourth support block 420 and the fifth support block 430 are respectively arranged at the two end portions of the base 200 along the X-axis direction, and the fourth support block 420 and the fifth support block 430 are symmetrically arranged; the third support block 410 is located between the fourth support block 420 and the fifth support block 430; the tops of the third support block 410, the fourth support block 420 and the fifth support block 430 are all in contact with the bottom of the second crossbeam 120 of the sand core.
[0028] Specifically, an avoidance space is formed between the fourth support block 420 and the third support block 410 and between the fifth support block 430 and the third support block 410. When the second beam 120 is placed on the third support block 410, the fourth support block 420 and the fifth support block 430 and fits together, the thin structure on the second beam 120 is located in the avoidance space, thereby preventing the thin structure on the second beam 120 of the sand core from directly contacting the base 200.
[0029] Furthermore, if Figure 2 As shown, a fifth avoidance groove 411 is provided in the middle of the third support block 410, and the fifth avoidance groove 411 can accommodate the protrusion at the bottom of the second cross beam 120 of the sand core to avoid interference between the protrusion and the base 200 during the transportation of the sand core.
[0030] Furthermore, if Figure 2-4 As shown, a first avoidance groove 510 for accommodating the bottom protrusion of the first longitudinal beam 130 of the sand core, a first support portion 520 and a second support portion 530 for supporting the first longitudinal beam 130 of the sand core are sequentially provided in the first cavity 500 along the Y-axis direction. The heights of the first avoidance groove 510, the first support portion 520 and the second support portion 530 are successively increased in a stepped manner so that the first avoidance groove 510, the first support portion 520 and the second support portion 530 can be adapted to the first longitudinal beam 130 of the sand core, and the tops of the first support portion 520 and the second support portion 530 are both provided with inclined surfaces; the first cavity 500 and the second cavity 600 have the same structure.
[0031] When in use, the first longitudinal beam 130 of the sand core is placed in the first cavity 500, the protrusion on the first longitudinal beam 130 of the sand core is placed in the first avoidance groove 510, and the bottom of the first longitudinal beam 130 of the sand core is respectively in contact with the top of the first support part 520 and the second support part 530. Among them, the bottom of the first longitudinal beam 130 of the sand core has a complex curved surface, and there is a gap between the inclined surface at the top of the first support part 520 and the second support part 530 and the complex curved surface, so as to avoid the curved surface directly interfering with the first support part 520 and the second support part 530, thereby reducing the breakage of the sand core during transportation. The situation where the second longitudinal beam 140 of the sand core is placed in the second cavity 600 is the same as above, and will not be repeated here.
[0032] Furthermore, if Figure 2-4As shown, a third support portion 540, a second avoidance groove 550 and a fourth support portion 560 are sequentially provided in the first cavity 500 along the Y-axis direction. The third support portion 540 is located at the end of the first cavity 500, the fourth support portion 560 is adjacent to the first avoidance groove 510, the first avoidance groove 510 is located between the fourth support portion 560 and the first support portion 520, and the second avoidance groove 550 is located between the third support portion 540 and the fourth support portion 560; the third support portion 540 and the fourth support portion 560 are at the same height and fit in with the bottom of the first longitudinal beam 130 of the sand core.
[0033] Specifically, the first longitudinal beam 130 of the sand core is placed in the first cavity 500, and the first avoidance groove 510 can accommodate the protrusion on the bottom curved surface of the first longitudinal beam 130 of the sand core. The curved surface of the first longitudinal beam 130 of the sand core near the connection between the first longitudinal beam 130 of the sand core and the first cross beam 110 of the sand core fits with the third support part 540 and the fourth support part 560 to reduce the collision during the transportation of the sand core. The second longitudinal beam 140 of the sand core is placed in the second cavity 600 in the same manner as above, which will not be repeated here.
[0034] Furthermore, if Figure 2-3 As shown, the third support portion 540 is provided with a third avoidance groove 570 on the side away from the second avoidance groove 550 to avoid interference between the connection between the first cross beam 110 and the first longitudinal beam 130 of the sand core and the connection between the first cross beam 110 and the second longitudinal beam 140 of the sand core and the base 100.
[0035] Furthermore, if Figure 2-3 As shown, a fourth avoidance groove 330 and a fifth support portion 340 are provided between the third avoidance groove 570 and the first support seat 300, and the fourth avoidance groove 330 is located between the first support seat 300 and the fifth support portion 340. It should be noted that the fourth avoidance groove 330 and the fifth support portion 340 are distributed on both sides of the first support seat 300.
[0036] When in use, the support blocks near both ends of the bottom of the first cross beam 110 of the sand core abut against the fifth support portion 340, and the fourth avoidance groove 330 can accommodate the protrusions at the bottom of the first cross beam 110 of the sand core to reduce the collision of the sand core during transportation.
