[0021] After adopting the above structure, the improved toilet pouring forming equipment and process have at least the following beneficial effects:

[0022] I. When clamping, the upper end seat and the middle frame move towards the lower end seat, at this time, the first lifting oil cylinder and the second lifting oil cylinder serve as driving power, and the piston rod of the pressurizing cylinder serves as a guide column for the upper end seat and the lower end seat.

Thus, when tilted, the swing range of the upper end of the upper end seat is smaller, and the overall molding equipment is more compact. Reduce the space occupied. Moreover, because the position of the horizontal axis is closer to the center of gravity of the mold, the tilting cylinder is driven to turn more easily, and a smaller cylinder can be selected, reducing the cost of the equipment.

[0024] III. In use, the first cylinder drives the mounting seat and the slider to move along the sliding guide rail, so that the side mold approaches the middle mold.

[0036] In this way, the present invention relates to an improved toilet casting molding equipment and process. When the mold is closed, the upper end seat 1 and the middle frame 2 move toward the lower end seat 3. At this time, the first lifting cylinder 12 and the second lifting cylinder 13 serve as driving power, and the piston rod of the pressurizing cylinder 14 serves as a guide column for the upper end seat 1 and the lower end seat 3. When pressurizing, hydraulic oil is pressurized and injected into the pressurizing cylinder 14 to achieve compression between the upper end seat 1 and the lower end seat 3, that is, compression between the upper mold 11, the middle mold 21 and the lower mold 31. The piston rod of the pressurizing cylinder 14 is used as a guide column to reduce manufacturing costs.

By arranging the first vertical column 41 and the second vertical column 32, the position of the horizontal axis is raised when the mold set rotates, and the position of the horizontal axis is closer to the center of the middle die 21 and the overall gravity center position, so that the swing range of the upper end of the upper end seat 1 is smaller when tilting, and the overall forming equipment is more compact. The occupied space is reduced. Moreover, since the position of the horizontal axis is closer to the gravity center position of the mold, the inclination oil cylinder 42 is easier to drive to overturn, and a smaller specification oil cylinder can be selected, thereby reducing the cost of the equipment.

[0039] Preferably, the first vertical column 41 comprises two vertical rods 411 and a bearing seat 412, the two vertical rods 411 are arranged in parallel with each other, the lower ends of the two vertical rods 411 are fixedly connected with the base 4, and the upper ends of the two vertical rods 411 are fixedly connected with the bearing seat 412; the inner ring of the bearing seat 412 is connected with a rotating shaft, and the rotating shaft is fixedly connected with the second vertical column 32; and the second vertical column 32 and the third vertical column 33 are arranged in parallel.
