A lifting assembly is provided in the middle of the door-type bracket, and the free end of the lifting assembly is connected to the pressure plate above the sand box through a connecting frame.

[0006] Furthermore, the sand box support includes a bottom plate and positioning shafts. The bottom plate is fixed to the lower part of the frame, and two positioning shafts are fixed to the bottom plate in parallel.

[0007] Furthermore, a sunken positioning groove is provided in the middle of the positioning shaft, and the contact position between the bottom of the sand box and the positioning shaft is a groove matching the positioning groove.

[0008] Furthermore, the upper front portion of the frame is an open structure, and rollers are installed at the bottom of the frame, and the rollers are driven by a motor.

[0009] Furthermore, the lifting assembly includes a hydraulic cylinder and a sleeve. The hydraulic cylinder is fixed to the middle of the door-shaped bracket, and the lower end of the door-shaped bracket is provided with a sleeve that matches the free end of the hydraulic cylinder.

[0010] Furthermore, the connecting frame includes a connecting plate and a T-shaped plate. The center of the connecting plate is fixedly connected to the free end of the hydraulic cylinder. Two T-shaped plates are respectively fixed on both sides of the connecting plate. The ends of the T-shaped plate are fixedly connected to the pressure plate above the sand box through a pressure block.

[0011] The beneficial effects of the conveniently movable casting sand box of the utility model are:

[0012] The utility model is a convenient and movable casting sand box. The positioning axis of the sand box bracket is used to assist in positioning the placement of the sand box, so that it can be quickly installed in place, so that the positions of the sand box and the pressure plate correspond to each other, which is convenient for quickly compacting the sand and soil. The connecting frame between the pressure plate and the lifting assembly improves the strength of the pressure plate, so that the downward pressure of each position of the pressure plate is uniform, ensuring that the sand and soil are compacted densely. The frame can realize the smooth and fast movement of the sand box, reduce the fluctuation of the casting mold during the movement, and will not delay the entry of other sand boxes for casting, thereby greatly improving the production efficiency of castings.

[0015] The conveniently movable casting sand box of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0017] See also Figure 1The present embodiment provides a casting sand box that is easy to move. The casting sand box is provided with lifting ears on both sides to facilitate the installation and positioning of the sand box. The pressure plate is used to compact the sand in the sand box, saving the time of mold making. The frame can move the sand box smoothly to ensure the integrity of the mold and improve the casting quality. It mainly includes a sand box 5 and a sand box bracket. The sand box 5 is placed on the sand box bracket, and the sand box bracket is installed at the lower part of the frame 1.

[0018] The sand box bracket includes a base plate 3 and a positioning shaft 4. A sunken positioning groove is provided in the middle of the positioning shaft 4. The contact position between the bottom of the sand box 5 and the positioning shaft 4 is a groove matching the positioning groove, which is convenient for the rapid positioning and placement of the sand box 5. The base plate 3 is fixed to the lower part of the frame 1, and the two positioning shafts 4 are fixed in parallel on the base plate 3. The upper front part of the frame 1 is an open structure, and a lifting ear 7 is fixedly connected to the side wall of the sand box 5. A fork groove 6 is provided at the bottom of the sand box 5 to facilitate the insertion of the sand box 5 from the front side of the frame 1. A roller 2 is installed at the bottom of the frame 1, and the roller 2 is driven by a motor.

[0019] A door-shaped bracket 8 is installed on the upper part of the frame 1, and a lifting assembly is provided in the middle part of the door-shaped bracket 8. The free end of the lifting assembly is connected to the pressure plate 14 above the sand box 5 through a connecting frame. The lifting assembly includes a hydraulic cylinder 9 and a sleeve 10. The hydraulic cylinder 9 is fixed in the middle part of the door-shaped bracket 8. The lower end of the door-shaped bracket 8 is provided with a sleeve 10 matching the free end of the hydraulic cylinder 9. The extension and contraction of the free end of the hydraulic cylinder 9 is guided and positioned to avoid displacement of the stroke and ensure uniform pressure at each position of the pressure plate. The connecting frame includes a connecting plate 11 and a T-plate 12. The center of the connecting plate 11 is fixedly connected to the free end of the hydraulic cylinder 9. Two T-plates 12 are respectively fixed on both sides of the connecting plate 11. The ends of the T-plate 12 are fixedly connected to the pressure plate 14 above the sand box 5 through a pressing block 13.

[0020] During use, the sand box is placed on the base plate by a forklift, and the positioning groove on the positioning shaft engages with the groove at the bottom of the sand box to quickly position and place the sand box. After the sand in the sand box is filled, the hydraulic cylinder drives the pressure plate to press down to compact the sand. The speed is fast and the compaction is tight to ensure the quality of the casting. After the casting is completed, it is moved to the ladle position and left after casting to avoid the movement of the ladle, improve safety, and not delay the subsequent casting of the sand box. It is efficient and safe.
