[0002] Static pressure casting is an advanced process for manufacturing high-quality, high-strength, and high-precision castings. Different from traditional gravity casting, static pressure casting presses the molten alloy into the mold cavity by means of mechanical pressure, hydraulic pressure, or air pressure, realizing the casting of high density, defect-free, and high dimensional accuracy of the castings. The sand box turnover device is an auxiliary device for the turnover of composite sand boxes, and it has been widely used in the field of casting production equipment.

The device lacks a fixing structure for the sand box, and the sand box may tilt or even fall when lifted, posing a safety hazard. Moreover, driving the sand box to rotate with iron chains is relatively slow, greatly reducing the working efficiency of the sand box turnover device for static pressure casting.

The multiple sliders are slidably connected to the surfaces of multiple slide rails, so that the operation of the two cylinders drives the stable movement of the two connecting plates. The movement of the two connecting plates drives the movement of two rotating columns. The movement of the two rotating columns drives the movement of two circular plates. The movement of the two circular plates drives the movement of two fixing components. The movement of the two fixing components drives the movement of the sand box. When the sand box reaches the appropriate position, at this time, stop operating the two cylinders through the external controller and operate two synchronous motors. The operation of the two synchronous motors drives the rotation of two rotating rods. The rotation of the two rotating rods drives the rotation of two small gears. The two small gears, two chains and two large gears are correspondingly meshed with each other, so that the two large gears rotate. The rotation of the two large gears drives the rotation of two rotating columns. The rotation of the two rotating columns drives the rotation of two circular plates. The rotation of the two circular plates drives the rotation of two discs. The rotation of the two discs drives the rotation of two fixing components.

[0033] Working principle: When it is necessary to fix the sand box for static pressure casting, first, two forward and reverse motors 808 are operated through an external controller. The operation of the two forward and reverse motors 808 drives the rotation of two threaded rods 807. The rotation of the two threaded rods 807 drives the movement of two sliding plates 805 on the surfaces of multiple cross bars 804. The movement of the two sliding plates 805 on the surfaces of multiple cross bars 804 drives the movement of multiple long plates 813. The movement of multiple long plates 813 drives the movement of four movable plates 810 in multiple second through slots 809 in a direction away from each other, so that four clamping arms 811 and four clamping plates 812 move in a direction away from each other. When the distance between the clamping plates 812 is greater than the size of the sand box, at this time, the sand box is placed at the center of the surface of the bottom plate 1. Then, the forward and reverse motors 808 are operated in the reverse direction, so that multiple clamping plates 812 move in a direction close to each other. Multiple clamping plates 812 cooperate in pairs to achieve the purpose of clamping and fixing the sand box. At this time, the operation of the two forward and reverse motors 808 is stopped. Through the cooperation of the above structures, multiple clamping plates 812 achieve the effect of clamping and fixing the sand box, avoiding the inclination or even dropping of the sand box when the sand box is lifted, and improving the safety of the sand box turning device for static pressure casting; When it is necessary to rotate the sand box for static pressure casting, the sand box is fixed in advance through the fixing component 8. Subsequently, two cylinders 501 are operated through an external controller. Two connecting plates 4 and multiple sliders 3 are fixedly connected correspondingly. Multiple sliders 3 are slidably connected to the surfaces of multiple slide rails 2. Thus, the operation of the two cylinders 501 drives the stable movement of the two connecting plates 4. The movement of the two connecting plates 4 drives the movement of two rotating columns 6. The movement of the two rotating columns 6 drives the movement of two circular plates. The movement of the two circular plates drives the movement of two fixing components 8. The movement of the two fixing components 8 drives the movement of the sand box. When the sand box reaches the appropriate position, at this time, the external controller stops the operation of the two cylinders 501 and operates two synchronous motors 904. The operation of the two synchronous motors 904 drives the rotation of two rotating rods 903. The rotation of the two rotating rods 903 drives the rotation of two small gears 905. The two small gears 905, two chains 906 and two large gears 901 are correspondingly meshed with each other. Furthermore, the rotation of the two large gears 901 is driven. The rotation of the two large gears 901 drives the rotation of two rotating columns 6. The rotation of the two rotating columns 6 drives the rotation of two circular plates. The rotation of the two circular plates drives the rotation of two discs 7. The rotation of the two discs 7 drives the rotation of two fixing components 8. The rotation of the two fixing components 8 drives the rotation of the sand box. When the sand box rotates 306 degrees, at this time, the external controller stops the operation of the two synchronous motors 904 and resets the cylinder 501. In this way, the turning of the sand box is completed. Through the cooperation of the above structures, through the cooperation of the small gear 905, large gear 901 and chain 906, the sand box is driven to rotate quickly, greatly improving the efficiency of sand box turning.
