[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 5The utility model provides a sand box production feeding mechanism, including a workbench 1; a processing assembly is arranged on the workbench 1, and the processing assembly includes a work box 16, which is used to perform sand filling processing on the mold; a fixed block 3 is fixedly connected to one side of the workbench 1; two fixed blocks 3 are provided, and are symmetrically arranged on both sides of the workbench 1; a support rod 4 is fixedly connected to the top of the fixed block 3; a telescopic rod 5 is fixedly connected to the top of the fixed block 3 on one side of the support rod 4; two telescopic rods 5 are provided, and are symmetrically arranged on both sides of the support rod 4; a sliding block 6 is fixedly connected to the output end of the telescopic rod 5; a sand storage box 7 is fixedly connected to the sliding block 6; a funnel 15 is fixedly connected to the bottom of the sand storage box 7; two funnels 15 are provided, and are symmetrically arranged at the bottom of the sand storage box 7; when working, The telescopic rod 5 is telescoped by an external driving device, and the telescopic rod 5 is telescoped to slide the sliding block 6 upward along the supporting rod 4, and the sand storage box 7 fixedly connected to the middle part of the sliding block 6 is lifted upward. After the sand storage box 7 is lifted, the working box 16 is sent to the bottom of the sand storage box 7, and then the funnel 15 at the bottom of the sand storage box 7 is placed into the working box 16 by the telescopic rod 5 lifting and lowering, and then the sand is released from the sand storage box 7, and the sand enters the working box 16 through the funnel 15. According to the height of the sand laid in the working box 16, the telescopic rod 5 is slowly raised to drive the funnel 15 to move upward together, so that the sand can completely fill the working box 16, thereby avoiding the damage of the plastic mold placed in the working box 16 due to the height difference caused by the falling sand, and also avoiding the large amount of dust generated by the falling sand at a high place, causing certain pollution.

[0026] Further, such as Figures 2 to 4 As shown, a thread groove 8 is provided on the workbench 1; there are two thread grooves 8, and they are symmetrically arranged on the workbench 1; a screw rod 9 is rotatably connected in the thread groove 8; a threaded slider 18 is threadedly connected to the screw rod 9; there are two threaded sliders 18, and they are equidistantly arranged on the screw rod 9; a moving platform 10 is fixedly connected to the threaded slider 18; one end of the workbench 1 is located at the same horizontal position as the screw rod 9 and is fixedly connected to a motor 14. When working, the motor 14 drives the screw rod 9 to rotate in the thread groove 8, and the screw rod 9 rotates to move the threaded slider 18 threadedly connected to the screw rod 9, and the threaded slider 18 moves to allow the moving platform 10 to translate. Because after the sand filling is completed, the working box 16 needs to be moved under the pouring equipment to pour molten iron, which can make the equipment more convenient to operate and avoid the need for staff to disassemble the working box 16 back and forth for operation.

[0027] Further, such as Figure 3 and Figure 4As shown, a vibrator 17 is fixedly connected to the movable platform 10; a plurality of vibrators 17 are provided and are equidistantly arranged in the movable platform 10; a support plate 11 is fixedly connected to the top of the vibrator 17; the top of the support plate 11 is movably connected to the working box 16. During operation, after sand is poured into the working box 16, the sand is not dense and is in a loose state in the working box 16, and cannot completely surround the plastic mold. Therefore, when the sand is poured into the vibrator 17 on the movable platform 10, the vibrator 17 vibrates, and the vibration of the vibrator 17 causes the support plate 11 and the working box 16 to vibrate. The vibration of the working box 16 makes the sand just poured into the working box 16 denser, and the plastic mold is wrapped more completely, so as to avoid the molten iron flowing along the sand gaps when pouring the molten iron, causing the product to deform.

[0028] Further, such as Figure 4 and Figure 5 As shown, a threaded hole 21 is provided on the support plate 11; there are four threaded holes 21, which are respectively arranged at the four corners of the support plate 11; a bolt 12 is threadedly connected to the threaded hole 21; a connecting block 13 is fixedly connected to the working box 16; the connecting block 13 is movably connected to the bolt 12. When working, the working box 16 is first placed on the support plate 11, and then the bolt 12 is inserted into the threaded hole 21 on the support plate 11 through the connecting block 13. After alignment, the staff rotates the bolt 12 to fix the working box 16 and the connecting block 13 on the support plate 11 to avoid shaking and displacement during work.

[0029] Further, such as Figure 4 As shown, a filter plate 19 is fixedly connected inside the sand storage box 7; a discharge plate 20 is slidably connected to the sand storage box 7 below the filter plate 19. When working, the filter plate 19 is arranged inside the sand storage box 7 to filter impurities in the sand to prevent the impurities in the sand from affecting the quality of the product. The discharge plate 20 inside the sand storage box 7 is to allow the sand to flow or stop the sand from flowing as needed, thereby playing the role of a switch.

[0030] Further, such as Figure 1 As shown, a support leg 2 is fixedly connected to the bottom of the workbench 1; there are multiple support legs 2, which are equidistantly arranged at the bottom of the workbench 1. When working, the support legs 2 at the bottom of the workbench 1 play a supporting role, and the multiple support legs 2 are for maintaining the stability of the workbench 1.

[0031] Working principle: the telescopic rod 5 is telescoped through an external driving device, and the telescopic rod 5 is telescoped to slide the sliding block 6 upward along the supporting rod 4, and the sand storage box 7 fixedly connected to the middle part of the sliding block 6 is lifted upward. After the sand storage box 7 is lifted, the working box 16 is sent to the bottom of the sand storage box 7, and then the funnel 15 at the bottom of the sand storage box 7 is placed into the working box 16 through the telescopic rod 5. Then the sand is released from the sand storage box 7, and the sand enters the working box 16 through the funnel 15. According to the height of the sand laid in the working box 16, the telescopic rod 5 is slowly raised to drive the funnel 15 to move upward together, so that the sand can completely fill the working box 16. This avoids the impact of the plastic mold placed in the working box 16 on the sand due to the height difference, and also avoids the large amount of dust generated by the falling sand at a high place, causing certain pollution.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
