[0027] The fixed assembly 7 comprises a positioning ring 71 fixedly installed on the surface of the discharge pipe 6, a positioning block 72 fixedly installed inside the positioning ring 71, a fixed plate 73 fixedly installed on the inner side of the control plate 83, a slide plate 74 which needs to be manually pulled upwards to drive the slide plate 74 to slide upwards inside the fixed plate 73, an insertion plate 78 which slides upwards inside the control plate 83 when the slide plate 74 slides, an insertion rod 77 which slides upwards when the insertion plate 78 slides, the slide plate 74 being slidingly connected inside the fixed plate 73, a fixed spring 75 fixedly installed on the bottom of the slide plate 74 and inside the fixed plate 73, a pull rod 76 fixedly installed on the surface of the slide plate 74, the insertion plate 78 being fixedly installed on the inner side of the slide plate 74, the insertion rod 77 being fixedly installed on the bottom of the insertion plate 78, the pull rod 76 being manually released after adjustment to reset the slide plate 74 under the action of the fixed spring 75, the insertion rod 77 being reinserted inside the positioning ring 71 for fixation, the convenience of discharge flow adjustment being improved, the stability of use after flow adjustment being enhanced, a sliding groove 820 being formed on the surface of the rotating disc 82 to drive the slide rod 85 to slide on the surface of the rotating disc 82, a strip-shaped groove 840 being formed on the surface of the connecting strip 84 to drive the connecting rod 87 to slide on the surface of the connecting strip 84, a recess 810 being formed on the outer side of the fixed disc 81 to drive the control plate 83 to slide on the outer side of the fixed disc 81 to rotate the rotating disc 82, a square groove 860 being formed on the surface of the control block 86 to drive the slide plate 74 to slide inside the control block 86 and adjust the insertion rod 77 up and down.

[0028] When the casting muller is in use, the materials are poured into the inlet 5 and mixed by the stirring blades. The stirring blades are generally installed on the rotating main shaft, and when the main shaft rotates, the blades rotate at high speed. The spiral blades can generate axial and tangential forces during rotation, lifting the materials upward from the bottom of the mixing drum 4 and pushing them outward, forming a circulating flow in the drum, thereby achieving uniform mixing. With the continuous rotation of the stirring blades, the materials in the mixing drum 4 are constantly turned over. The materials near the blades are first driven, and then the power is transmitted to other materials through mutual collision and friction between the materials. This turning makes the materials at different positions exchange positions, forming convection. When the discharge flow needs to be adjusted, the control panel 83 can be manually operated to slide outside the fixed disc 81. When the control panel 83 slides, it drives the rotation of the turntable 82. When the turntable 82 rotates, it drives the connecting rod 87 to slide on the surface of the turntable 82 through the sliding groove 820 on its surface. When the connecting rod 87 slides, it drives one end of the control block 86 to move in the sliding direction of the connecting rod 87. When the control block 86 slides, it slides on the surface of the connecting strip 84 through the sliding rod 85 on its surface, causing the control block 86 to move towards the center point of the fixed disc 81. When the control block 86 moves towards the center point, the aperture of the discharge pipe 6 can be reduced, thereby reducing the discharge flow. When the control panel 83 is manually operated in the opposite direction, the control panel 83 drives the turntable 82 to rotate in the opposite direction inside the fixed disc 81, thereby causing the control block 86 inside to move away from the center point of the fixed disc 81, causing the aperture of the discharge pipe 6 to be enlarged. This prevents the amount of sand filling the mold from being too large or too small when the discharge pipe 6 discharges, which does not meet the design requirements and can cause the size of the casting to deviate, improving production efficiency and work convenience.

[0029] When adjusting, first manually pull the pull rod 76 upward to drive the sliding plate 74 to slide upward inside the fixed plate 73. When the sliding plate 74 slides, it drives the insertion plate 78 to slide upward inside the control panel 83. When the insertion plate 78 slides, it drives the insertion rod 77 to slide upward, thereby releasing the restriction of the positioning ring 71 on the insertion rod 77, allowing the rotation of the control panel 83 to be controlled. After adjustment is complete, the pull rod 76 can be manually released to allow the sliding plate 74 to reset under the action of the fixed spring 75, causing the insertion rod 77 to be reinserted inside the positioning ring 71 for fixation, improving the convenience of discharge flow adjustment and enhancing the stability of the flow adjustment after use.

Therefore, the modification or improvement without departing from the utility model thought spirit, all are within the protection scope of the utility model.
