[0002] Sand cores are the material used to create cores in foundry production. They are produced by a core-making machine. After the core-making machine completes the core-making process, workers need to manually remove the sand cores from the machine. However, since the sand cores remain high up in the machine after production and are heavy, direct handling of the sand cores is not only difficult but also prone to safety accidents. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the present application provides a coring device that is easy to carry and safe and reliable.

[0027] The present application is further described in detail below with reference to the accompanying drawings.
[0028] See also Figure 1 As shown, a coring device is shown, which includes a horizontally arranged base 1, a slide 4 slidable along the length direction of the base 1 on the base 1, a coring fork 2 that can be raised and lowered on the slide 4, and a driving assembly 3 for driving the slide 4 to slide and driving the coring fork 2 to rise and fall.
[0029] In this embodiment, the drive assembly 3 includes a translation module 31 for driving the slide 4 to slide, and a lifting module 32 for driving the coring fork 2 to rise and fall. During coring, the lifting module 32 drives the coring fork 2 to rise and reach the side of the sand core. The translation module 31 then drives the slide 4 to slide forward, causing the slide 4 to drive the coring fork 2 to extend into the bottom of the sand core. The translation module 31 then drives the slide 4 to slide backward, causing the slide 4 to retract the coring fork 2 carrying the sand core. The lifting module 32 then drives the coring fork 2 to descend to a lower position. At this point, workers can move the sand core from the coring fork 2 at a lower position, eliminating the need to climb to a higher location for coring. This not only reduces the difficulty of manual handling but also eliminates safety hazards.
[0030] Among them, the translation module 31 includes a gear rotatable around the vertical direction and arranged on the slide 4, a motor for driving the gear to rotate, and a rack arranged on the base 1 and extending along the length direction of the base 1. The motor is arranged on the slide 4, and the gear is coaxially connected to the output shaft of the motor. The gear is meshed with the rack, and the gear is driven to rotate by the motor. During its rotation, the gear can produce relative movement with the rack, thereby realizing the sliding of the slide 4 on the base 1.
[0031] The precise coordination of the gear and rack enables fine adjustment of the sliding distance of the slide 4, ensuring that the coring fork 2 can accurately bear on the bottom of the sand core and transport the sand core, thereby improving the stability of the coring fork 2 in transporting the sand core.
[0032] The lifting module 32 includes a cylinder arranged on the slide 4 and four guide rods connected to the coring fork 2. The piston rod of the cylinder is connected to the coring fork 2 and can drive the coring fork 2 to rise and fall. The four guide rods are slidably arranged on the four corners of the slide 4.
[0033] In this embodiment, the coring fork 2 includes a fork base 21, a fork body 22 disposed on the fork base 21 and extending in a direction away from the fork base 21, and the fork body 22 includes a plurality of spaced-apart fork rods 221. Each fork rod 221 has a connecting end connected to the fork base 21 and a coring end away from the fork base 21. The width of the coring end gradually decreases from the connecting end to the coring end. The coring end with a gradually decreasing width facilitates insertion into the bottom of the sand core during coring. The fork base 21 is movably disposed on the slide 4. The translation direction of the slide 4 is the same as the extension direction of the fork body 22. The fork rods 221 can be moved in the direction from the connecting end to the coring end under the drive of the fork base 21, so that the coring end can be inserted into the bottom of the sand core and support and transport the sand core.
[0034] The spacing between the multiple fork rods 221 is adjustable. The fork base 21 is further provided with two parallel adjustment slots 23 extending along the arrangement direction of the multiple fork rods 221. Each fork rod 221 is provided with two adjustment blocks 222 at its connecting end. The two adjustment blocks 222 are respectively mounted at the notches of the two adjustment slots 23. Each adjustment block 222 can slide along the extension direction of the corresponding adjustment slot 23. The coring fork 2 also includes a locking member (not shown in the figure) for locking the adjustment block 222 relative to the adjustment slot 23. The locking member is a locking bolt.
[0035] To adjust the spacing between the multiple fork rods 221, simply loosen the locking bolt, adjust the position of the adjustment block 222, and tighten the locking bolt again after adjustment. This allows the spacing between the multiple fork rods 221 to be adjusted based on specific coring needs, preventing smaller sand cores from falling through the gaps between adjacent fork rods 221. The two adjustment blocks 222 prevent the fork rods 221 from angularly deflecting due to single-point adjustment, thereby preventing subsequent coring from being affected. Furthermore, the locking member locks the adjustment block 222 relative to the adjustment slot 23, preventing the adjustment block 222 from accidentally sliding during coring and affecting the fork body 22's handling of the sand core.
[0036] In this embodiment, the slide 4 has connecting portions on both sides of its width, and the base 1 has supporting portions on both sides of its width. The two connecting portions correspond one-to-one to the two supporting portions. Two sliders 5 are provided at the lower end of each connecting portion, and a slide rail 6 is provided at the upper end of each supporting portion. The slide rail 6 extends along the length of the base 1. The sliders 5 are slidably connected to the slide rails 6. The slide rails 6 are provided with stoppers 7 at both ends of their extension direction for resisting the sliders 5. The slide 4 can move smoothly on the base 1 under the sliding cooperation of the sliders 5 and the slide rails 6. At the same time, the stoppers 7 can limit the slider 5 at the starting point and end point of the slide 4's sliding stroke, preventing the slider 4 from sliding excessively and affecting its handling of the sand cores.
[0037] Two positioning blocks 8 are respectively provided on each connecting part, and one of the bearing parts is provided with two sensing blocks 9 for sensing the positioning blocks 8 at both ends of the extension direction of the slide rail 6. The sensing blocks 9 are proximity sensors, which can sense the positioning blocks 8 at the starting point and end point of the slide rail 6 to determine the sliding position of the slide 4, so as to facilitate the control of the sliding stroke of the slide 4 and realize the control of the coring process of the coring fork 2.
[0038] The implementation principle of a coring device in an embodiment of the present application is as follows:
[0039] The fork seat 21 is driven by the cylinder to rise and reach the side of the sand core, and then the motor drives the gear to rotate forward. During the relative movement of the gear and the rack, the slide 4 moves toward the sand core and drives the fork body 22 to extend into the bottom of the sand core. Then the motor drives the gear to rotate in the opposite direction, and the slide 4 moves in the direction away from the sand core and drives the fork body 22 and the sand core thereon to move. After the fork body 22 moves into place, the cylinder drives the fork seat 21 to descend, and the fork body 22 reaches a lower place. At this time, the worker can move the sand core on the fork body 22.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
