[0002] "Filling the box" in sand casting is an important step in the casting process, which is directly related to the quality and precision of the casting. In sand casting, filling the box is the first and most important step. At this stage, workers will use the sand box to shape the outer shape of the casting. The sand box is usually made of refractory materials and filled with sand molds. Then space is left in the sand mold to accommodate the molten metal. Precise control of the filling process is essential to ensure that the shape and size of the sand box exactly match the final casting. Special molding sand is filled into the sand box. These molding sands have been specially treated and have good fluidity and hardening properties. When filling, they need to be compacted evenly layer by layer to ensure the density and strength of the sand mold.
[0003] At present, the process of pouring the molding sand into the sand box is manually operated. After each time a certain amount of molding sand is poured in, the molding sand needs to be manually flattened before compacting, which is time-consuming and labor-intensive and has low sand injection efficiency.
[0004] Therefore, a sand mold casting box filling device is proposed to solve the above problems. Utility Model Content

When the sand mold casting filling device is in use, the molding sand is first injected into the storage hopper 3, and then the sand box 6 is moved to the storage hopper The hopper 3 moves in the direction of the hopper 3. At this time, one end of the sand box 6 supports one end of the sealing plate 24 and drives the sealing plate 24 to slide at the same time. Since the function of the sealing plate 24 is to block the discharge port of the storage hopper 3, the discharge port exposed when the sealing plate 24 slides is now located above the sand box 6. Therefore, the molding sand will enter the sand box 6. During the movement of the sand box 6, the discharge port becomes larger and larger, so that the molding sand gradually fills the sand box 6. At this time, the sand box 6 is slid to its original position. During this process, the sealing plate 24 will slide in the opposite direction again under the action of the telescopic rod 22 to block the discharge port. Therefore, the molding sand can be quickly injected into the sand box 6 without manual sand injection and manual flattening, thereby effectively improving the efficiency of filling the box during the sand mold casting process.
[0027] In this embodiment, if Figure 1 and Figure 4 As shown, a fixed block 4 is fixedly installed at one end of the top of the processing table 1, and an electric push rod 5 is fixedly installed on the inner side of the fixed block 4. A slide groove 11 is symmetrically opened on the top of the processing table 1, and a slide plate is symmetrically installed on the bottom of the sand box 6. The thickness of the slide plate is the same as the width of the inner side of the slide groove 11. The sand box 6 is slidably connected to the slide groove 11 through two slide plates, and one end of the sand box 6 is fixedly connected to one end of the electric push rod 5, so the electric push rod 5 can drive the sand box 6 to slide back and forth along the direction of the slide groove 11.
[0028] In this embodiment, if Figure 1 and Figure 2 As shown, a baffle 21 is installed on the discharge mechanism 2, and the baffle 21 is installed on the edge of one end of the top of the processing table 1. The telescopic rod 22 has two ends of the inner side surfaces respectively installed with the baffle 21, and a spring 23 is sleeved and installed on the outer ring surface of the telescopic joint of the telescopic rod 22. One end of the blocking plate 24 has a right-angle bend, and one end of the two telescopic rods 22 is respectively connected to the two ends of the outer side surface of the right-angle side of the blocking plate 24. At this time, when the blocking plate 24 is compressed, the telescopic rod 22 and the spring 23 will be squeezed. When the blocking plate 24 loses the squeezing force, the spring 23 will push the blocking plate 24 to its original position.
[0029] In this embodiment, if Figure 1As shown, a support frame 7 is installed on the longer side of the processing table 1. One end of the inner top of the support frame 7 is installed with a hydraulic telescopic column 71. The bottom of the hydraulic telescopic column 71 is fixedly connected to a pressing plate 72. The bottom edge of the pressing plate 72 has the same size as the inner top edge of the sand box 6. After the sand box 6 moves to one end of the chute 11, the pressing plate 72 is located directly above the sand box 6. Therefore, after injecting molding sand into the sand box 6, the hydraulic telescopic column 71 can drive the pressing plate 72 to compact the molding sand in the sand box 6.
[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a blanking groove 31 is opened at the inner bottom of the storage hopper 3. A through groove 32 matching the size of the sand box 6 is opened between the two side surfaces at the bottom of the storage hopper 3. The bottom discharge port of the blanking groove 31 is located at the inner top of the through groove 32. Card slots 33 are opened at both ends of the inner top of the through groove 32. The plugging plate 24 is slidably installed inside the card slots 33. When one end of the sand box 6 slides into the inner side of the through groove 32, the top edge of one end of the sand box 6 fits with the top edge of one end of the plugging plate 24. The length dimension of the sand box 6 is the same as the length dimension of the discharge port. Therefore, when the sand box 6 slides into the inside of the through groove 23, it will squeeze the plugging plate 24 to slide, enabling the molding sand to enter the sand box 6. At the same time, when the sand box 6 slides out in the opposite direction, the plugging plate 24 slides back to block the discharge port again under the action of the spring 23.
[0031] Working principle: When this sand mold casting pouring box device is in use, first inject molding sand into the storage hopper 3, and then use the electric push rod 5 to push the sand box 6 to slide on the chute 11 towards the inner side of the through groove 32. At this time, one end of the sand box 6 presses against one end of the plugging plate 24 and drives the plugging plate 24 to slide inside the card slots 33. Since the function of the plugging plate 24 is to block the discharge port of the storage hopper 3, the discharge port exposed when the plugging plate 24 slides is located above the sand box 6 at this moment. Therefore, the molding sand will enter the sand box 6. During the movement of the sand box 6, the discharge port becomes larger and larger, enabling the molding sand to gradually fill the sand box 6. Subsequently, the sand box 6 is pulled back to its original position by the electric push rod 5, and the plugging plate 24 slides back to its original position under the action of the spring 23. Therefore, the molding sand can be quickly injected into the sand box 6 without manual sand injection and manual leveling, thus effectively improving the pouring efficiency during the sand mold casting process. Finally, after injecting molding sand into the sand box 6, the hydraulic telescopic column 71 can drive the pressing plate 72 to compact the molding sand in the sand box 6.
[0032] All the technical features in this embodiment can be freely combined according to actual needs.
[0033] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
