Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to a resin sand molding device. Background Technology

[0002] Resin sand refers to molding sand or core sand that uses synthetic resin as a binder for sand particles. After the mold or core is made from resin sand, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of a curing agent, thereby giving the mold or core the necessary strength.

[0003] For example, patent document CN220127539U discloses a resin sand molding device with a structure that saves resin sand usage. The mold is placed on a placement plate, and the operator moves the sand funnel using an auxiliary arm, causing the sand guide pipe to move above the mold. The valve is then opened, allowing the sand funnel to begin filling the mold with resin sand, thus initiating the resin sand molding process. During the actual molding process, the resin sand needs to be manually tamped down using a tamping rod to ensure complete filling. Since the operator needs to work beside the mold, the resin sand falls from above into the mold. During this process, if the operator is not careful, resin sand may fall on them, which is not only labor-intensive but also poses a certain degree of danger. Utility Model Content

[0004] The purpose of this invention is to provide a resin sand molding device to solve the above-mentioned problems.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-7As shown, a resin sand molding device includes a base 1, a material bucket 2 fixed to the top of the base 1, the material bucket 2 containing resin sand, an auger conveyor 3 fixed to the bottom of the material bucket 2, a rotating mechanism 6 mounted on the top of the base 1, a vibrating mechanism 7 mounted on the rotating mechanism 6, a clamping mechanism 8 mounted on the top of the vibrating mechanism 7, and a mold 9 placed on the vibrating mechanism 7. The mold 9 is located below the discharge end of the auger conveyor 3, which is used to transport the resin sand to the mold 9. A tamping mechanism 4 is mounted on the auger conveyor 3, and the tamping mechanism 4 includes a screw... The mounting base 401 is fixed on the auger conveyor 3. Sleeves 402 are fixed to the bottom of both ends of the mounting base 401 by screws. Movable blocks 403 are slidably connected inside the sleeves 402. The movable blocks 403 can move up and down and rotate. A tamping rod 404 is fixed to the bottom of the movable blocks 403. The movable blocks 403 drive the tamping rod 404 to move up and down. The tamping rod 404 tamps the resin sand in the mold 9 to make the resin sand more compact and ensure the molding quality. Lifting mechanisms 5 are provided at both ends of the mounting base 401 to drive the movable blocks 403 to move up and down.

[0027] The inner wall of the sleeve 402 is provided with a spiral groove 405. The side wall of the movable block 403 is fixed with a limiting ball 406, which slides in conjunction with the spiral groove 405. The bottom end of the tamping rod 404 is fixed with a stirring rod 407. When the movable block 403 moves up and down, the limiting ball 406 moves along the spiral groove 405, thereby causing the movable block 403 to drive the tamping rod 404 to rotate. The tamping rod 404 drives the stirring rod 407 to rotate, and the stirring rod 407 agitates the resin sand to improve the tamping effect.

[0028] The lifting mechanism 5 includes a hydraulic cylinder 501, which is fixed to the top of the mounting base 401 by bolts. The output end of the hydraulic cylinder 501 extends into the sleeve 402 and is fixedly connected to a connecting block 502. The connecting block 502 is rotatably connected to the inside of the movable block 403. The hydraulic cylinder 501 drives the movable block 403 to move up and down through the connecting block 502. While moving up and down, the movable block 403 can rotate relative to the connecting block 502. Steel balls 503 are movably embedded in the side wall of the connecting block 502. By setting the steel balls 503, the friction between the connecting block 502 and the movable block 403 is reduced, making the rotation of the movable block 403 smoother.

[0029] The rotating mechanism 6 includes a rotary motor 601, which is fixed to the top of the base 1 by bolts. The output shaft of the rotary motor 601 is fixed to a turntable 602. A support rod 603 is welded to the bottom of the turntable 602. The support rod 603 provides support and stability to the turntable 602, ensuring that the turntable 602 rotates smoothly. An annular groove 101 is provided on the top of the base 1, and the bottom end of the support rod 603 is slidably connected in the annular groove 101.

[0030] The vibration mechanism 7 includes a vibration table 701, which is located above the turntable 602. A vibration motor 702 is fixed to the bottom center of the vibration table 701 by bolts. Guide rods 703 are fixed to both ends of the bottom of the vibration table 701. The guide rods 703 pass through the turntable 602 and are slidably connected to the turntable 602. A spring 704 is fixed between the vibration table 701 and the turntable 602. The spring 704 is sleeved around the guide rods 703. The vibration motor 702 drives the vibration table 701 to vibrate. The guide rods 703 guide the vibration table 701, causing the vibration table 701 to vibrate up and down in a small amplitude, making the resin sand in the mold 9 more compact.

[0031] The clamping mechanism 8 includes a fixed base 801, which is fixed to both ends of the top of the vibration table 701 by screws. The fixed base 801 is internally threaded with a screw 802. A clamping plate 803 is fixed to one end of the screw 802 near the mold 9, and a handle is fixed to the other end of the screw 802. The operator rotates the screw 802 by the handle, so that the clamping plate 803 is close to the mold 9 and clamps and fixes the mold 9.

[0032] Working principle: During use, the mold 9 is placed on top of the vibrating table 701. By turning the screw 802 with the handle, the screw 802 drives the clamping plate 803 to move. The two clamping plates 803 clamp the mold 9. The auger conveyor 3 transports the resin sand in the material bucket 2. The resin sand falls from the discharge end of the auger conveyor 3 into the mold 9. The hydraulic cylinder 501 drives the connecting block 502 to move up and down reciprocally. The connecting block 502 drives the movable block 403 to move up and down. The movable block 403 drives the stirring rod 407 to move up and down. The stirring rod 407 tamps the resin sand in the mold 9. Utilizing the cooperation of the spiral groove 405 and the limiting ball 406, the movable block 403 rotates when it moves up and down. 03 drives the tamping rod 404 to rotate, which in turn drives the stirring rod 407 to rotate. The stirring rod 407 agitates the resin sand inside the mold 9, improving the tamping effect. The rotary motor 601 drives the turntable 602 to rotate, which in turn drives the vibrating table 701 to rotate via the guide rod 703. The vibrating table 701 drives the mold 9 to rotate, causing relative displacement between the mold 9 and the tamping rod 404, thereby expanding the tamping range, achieving uniform tamping, and ensuring molding quality. The vibrating motor 702 drives the vibrating table 701 to vibrate, and the guide rod 703 guides the vibrating table 701 to vibrate up and down in small amplitudes, making the resin sand inside the mold 9 more compact and improving the molding quality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
