[0084] 1 to 11 , this embodiment provides a core making system, including a robot 600, a sand mixer 510, a coring workbench 520, a mold assembly workbench 530, and a small batch multi-variety core making machine; the sand mixer 510, the coring workbench 520, the mold assembly workbench 530, and the small batch multi-variety core making machine are arranged around the robot 600; a sling 626 is provided on each of the mold assembly 200 and the sand shooting head 330; the robot 600 includes a robotic arm 610 and a clamping member 620, and the clamping member 620 is rotatable. Installed on the robotic arm 610, the clamping member 620 includes a main beam 621, a fixed arm 622, a sliding arm 623 and an anti-rotation pressure head 624. The main beam 621 is installed on the robotic arm 610, the fixed arm 622 is installed at one end of the main beam 621, and the sliding arm 623 is slidably installed at the other end of the main beam 621. The ends of the fixed arm 622 and the sliding arm 623 away from the main beam 621 are provided with hooks 625 for adapting to the hanging column 626, and the anti-rotation pressure head 624 is provided on the side of the fixed arm 622 away from the sliding arm 623.

[0085] Specifically, the robot 600 can drive the mold assembly 200 to move between the coring workbench 520, the mold assembly workbench 530 and the lifting workbench 100, without the need for staff to participate in the transportation, thereby improving work efficiency.

[0086] In addition, a suspension column 626 is provided on the mold assembly 200 and the sandblasting head 330, and a clamping member 620 is provided on the robot 600. When the clamping member 620 clamps the sleeve frame 210, the sliding arm 623 on the clamping member 620 can slide outward, and then the fixed arm 622 and the hook 625 at the end of the sliding arm 623 move to the bottom of the suspension column 626, and then the sliding arm 623 moves inward, so that the hook 625 is connected to the suspension column 626, and at the same time, the anti-rotation pressure head 624 on the fixed arm 622 moves and abuts against the outer wall of the sleeve frame 210 to prevent the sleeve frame 210 from rotating.

[0087] The working process of the core making system provided in this embodiment is as follows: the sand adding robot adds sand to the sand shooting cylinder. During this process, a person manually checks whether the four locking hooks 260 between the upper mold 220 and the sleeve frame 210 have been pulled down and whether the upper mold 220 and the sleeve frame 210 are locked together. After confirmation, the start button is pressed to start the core making cycle;

[0088] The hooks 625 on the clamping member 620 hook the hanging posts 626 on both sides of the sleeve frame 210, and at the same time the anti-rotation pressure head 624 turns down to press the upper mold 220 to prevent the sleeve frame 210 and the upper mold 220 from turning over during the transportation process. The mold is transported as a whole to the forward extension table of the core making machine, and then the clamping member 620 releases the mold, and then the robot arm 610 pushes the secondary forward extension table 160 through the hook 625 (in the process of removing the mold, the robot arm 610 can pull out the secondary forward extension table 160 through the hook 625, and then hook the hanging posts 626 on both sides of the sleeve frame 210 through the hook 625, thereby moving the mold to the designated position), thereby pushing the mold to the center of the lifting workbench 100, that is, the center of the core making machine workbench;

[0089] Close the front door of the core making machine;

[0090] The lifting table 100 rises and lifts the mold to the shooting plate 332, ready for sand shooting;

[0092] The lifting platform 100 descends, and the air blowing hood 420 of the curing assembly 400 moves to the top of the lifting platform 100;

[0093] The lifting table 100 rises, and catalytic gas or hot air is introduced into the curing assembly 400 for air-blow curing. While the air-blow curing is in progress, sand is added to the upper part of the shooting cylinder to prepare for the next cycle of core making.

[0094] The lifting workbench 100 descends, the air blowing hood 420 returns to its original position and exits, and the front door of the core making machine opens;

[0095] The robot 600 moves the mold out of the core making center, drives the mold to flip 180 degrees, and places and positions it on the coring workbench 520 (at this time, the upper mold 220 is at the bottom);

[0096] Manually pull down the locking hook 260 between the upper mold 220 and the sleeve frame 210, and at the same time, lock the upper mold 220 and the work table of the coring workbench 520 together;

[0097] The robot 600 grips the sleeve frame 210, lifts and flips it over, and then transfers it to the mold assembly workbench 530 next to it and positions it properly.

[0098] The bottom mold 230 on the sand core is manually lifted and turned over, and then transferred to the mold assembly workbench 530 next to it and assembled in the sleeve frame 210;

[0099] Manually transfer the side mold piece 240 to the bottom mold 230 and place it in place using the inclined blocks around the inner wall of the sleeve frame 210;

[0100] Manually transfer the mold block 250 to the bottom mold 230 on the mold assembly workbench 530;

[0101] The robot 600 clamps the sand core and transfers it to the core storage cart in the sand core room 540. When the core storage cart is full, it can be removed and replaced.

[0102] Manually open the locking hook 260 between the upper mold 220 and the coring workbench 520 to unlock and separate them;

[0103] The gripper 620 of the robot 600 grips, lifts, flips, and transfers the upper mold 220 to the sleeve frame 210 ;

[0104] Manually pull down the locking hook 260 between the upper mold 220 and the sleeve frame 210 to lock the upper mold 220 and the sleeve frame 210 together, and the mold pre-assembly is completed;

[0105] Enter the next loop.
