[0027] Example

[0028] See also Figure 1-3 As shown:

[0029] The utility model provides a multi-directional adjustable push cylinder for a mobile mold frame, comprising: a cylinder 10 and an angle adjustment assembly 20. The tail of the cylinder 10 is installed on a displacement trolley, and a push rod of the cylinder 10 is connected to a main beam 40 of the mobile mold frame; a longitudinal sliding shoe 30 is provided at the connection between the push rod of the cylinder 10 and the main beam 40; the bottom of the longitudinal sliding shoe 30 is connected to the front end of the push rod of the cylinder 10, and the top of the longitudinal sliding shoe 30 is hung with the main beam 40.

[0030] In actual use, the angle adjustment component 20 is arranged at the connection between the cylinder 10 and the displacement trolley, and the angle adjustment component 20 forms an axial connection with the cylinder 10 in both the vertical and horizontal directions, and automatically adjusts the push rod angle of the cylinder 10 when the cylinder 10 pushes the main beam 40 of the mobile mold frame.

[0031] With such an arrangement, when the oil cylinder 10 pushes the main beam 40 to drive the mobile formwork forward, the center of gravity of the mobile formwork moves due to the displacement, causing the posture of the mobile formwork to have a deflection trend, and then in the process of the deflection trend, a reverse force is applied to the oil cylinder 10 through the push rod of the oil cylinder 10, and the oil cylinder 10 and the adjustment component are axially connected in the vertical and horizontal directions, thereby driving the oil cylinder 10 to deflect in the vertical and horizontal directions, so that the mobile formwork will not get stuck when pushing through the hole, and the movement will be more stable and smooth.

[0032] The angle adjustment assembly 20 is mainly composed of a connecting portion and a fixing portion.

[0033] The connecting part is axially connected to the top and bottom of the oil cylinder 10 housing; the top of the fixing part is axially connected to the side of the connecting part, and the bottom of the fixing part is fixed on the displacement trolley.

[0034] Through such a configuration, the oil cylinder 10 is connected to the shaft at the top and bottom of the housing to realize the horizontal rotation of the oil cylinder 10, while the top of the fixed part is connected to the side shaft of the connecting part to realize the vertical rotation of the oil cylinder 10. This allows the oil cylinder 10 to automatically adjust the pushing angle according to the reverse force applied by the moving mold frame during the process of pushing the moving mold frame.

[0035] The connecting portion is composed of an upper horizontal plate 22 , a lower horizontal plate 24 , a right vertical plate 25 and a left vertical plate 26 .

The area enclosed by the cross-shaped clamp ensures that the oil cylinder 10 can be rotated and adjusted to a certain angle in the horizontal and vertical directions, while limiting the excessive angular deflection of the oil cylinder 10 in the horizontal and vertical directions, thereby ensuring that the function of the oil cylinder 10 is not affected and the use effect is improved.

[0038] The upper horizontal plate 22 is provided with an upper mounting hole 221 for installing the upper vertical shaft, and the upper vertical shaft passes through the upper mounting hole 221 and is connected to the top end shaft of the tail of the cylinder 10 shell; the middle part of the lower horizontal plate 24 is provided with a steering base 241 for installing the lower vertical shaft, and the lower vertical shaft is connected to the bottom end shaft of the tail of the cylinder 10 shell.

There are gaps between the two vertical plates 21 and the right vertical plate 25 and the left vertical plate 26, so that the criss-cross clamp has no resistance during the deflection of the cylinder 10 in the vertical direction.

[0041] There are at least four triangular ribs 23 symmetrically distributed on both sides of the two vertical plates 21 , so that the vertical plates 21 and the triangular ribs 23 form a stable base for supporting the oil cylinder 10 to turn.
