[0028] In this embodiment, when in use, multiple mold rings 8 are connected to the support rings 7 at corresponding positions respectively, and the mold rings 8 and the support rings at each position are in contact with one end of the limit plate 4 away from the discharge pipe 1. When the mold needs to be set on the end of the discharge pipe 1, the mold ring 8 to be used is pushed to the position of the discharge port by the hydraulic push rod 5, and the mold ring 8 is passed over the end surface of the positioning convex ring 3 toward one side of the hydraulic push rod 5. At this time, the mold ring 8 is pushed upward by the ejection mechanism 9, so that the mold ring 8 and the corresponding support ring 7 are rotated sideways in the circumferential direction of the sliding rod 6. The mold ring 8 is moved to the position corresponding to the discharge port, and the mold ring 8 is moved to the position of the discharge port by the hydraulic push rod 5, so that the mold ring 8 is sleeved at the position of the discharge port, thereby achieving the effect of facilitating the replacement of the mold ring 8. When the mold ring 8 needs to be replaced, the mold ring 8 is pushed again by the hydraulic push rod 5 to pull the mold ring 8 out of the positioning convex ring 3. After the mold ring 8 is completely out of the positioning convex ring 3, the mold ring 8 is pushed back to the side of the limiting plate 4 away from the discharge pipe 1 by the ejection mechanism 9, so as to achieve the effect of quickly disassembling the mold ring 8;

[0029] In summary, the mold ring 8 is pushed by the hydraulic push rod 5 to control the position of the mold ring 8 and the discharge port, and then the mold ring 8 is controlled to rotate by the ejection mechanism 9, so that the axis of the mold ring 8 corresponds to the axis of the discharge pipe 1, and then the mold ring 8 is pushed by the hydraulic push rod 5 to make the mold ring 8 sleeved on the position of the positioning convex ring 3, thereby achieving the purpose of quickly installing the mold ring 8;

[0030] On the contrary, when the mold ring 8 is removed, the mold ring 8 is pushed by the hydraulic push rod 5 to be pulled out from the positioning convex ring 3. After the mold ring 8 is completely out of the positioning convex ring 3, the mold ring 8 is pushed back to the side of the limiting plate 4 away from the discharge pipe 1 by the ejection mechanism 9, so as to achieve the effect of quickly removing the mold ring 8.

[0031] Compared with the prior art, each mold ring 8 is located at the upper end of the limit plate 4 when not in use, and the axis lines of each mold ring 8 are on the same straight line, thereby effectively reducing the floor space occupied by multiple mold rings 8 and effectively improving the practicability of the equipment.

[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the outer side wall of one end of the positioning convex ring 3 away from the discharge pipe 1 is arc-shaped, and the diameter of the inner ring of the mold ring 8 is equal to the diameter of the outer ring of the positioning convex ring 3 .

[0033] In the present embodiment, by providing a positioning convex ring 3 with an arc-shaped outer wall at one end, when there is a certain error between the axis of the mold ring 8 and the axial center line of the discharge pipe 1, the mold ring 8 can be guided by the arc surface so that the position of the mold ring 8 corresponds to the axis of the discharge pipe 1, so as to facilitate the mold ring 8 to be mounted on the position of the discharge pipe 1.

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the support ring 7 is rectangular in shape, and one end is semicircular. The semicircular end of the support ring 7 is provided with a mounting hole 10 that matches the sliding rod 6, and the right-angle end of the support ring 7 is provided with a mounting groove 11.

[0035] In this embodiment, the installation groove 11 is provided for installing the mold ring 8, wherein the outer wall of the mold ring 8 is provided with an insertion rod that matches the installation groove 11, and when the mold ring 8 is installed, the expansion pad is wrapped around the outer wall of the insertion rod, so that when the insertion rod is inserted into the interior of the installation groove 11, an interference fit is formed, thereby achieving the purpose of fixing the mold ring 8 and the support ring 7, and the semicircular end face facilitates the rotation of the support ring 7 on the inner side of the limit plate 4, and the two side walls of the support ring 7 are used to cooperate with the limit plate 4 for limiting, so as to achieve the purpose of limiting the end face of the mold ring 8.

[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the limiting plate 4 is L-shaped and has an arc-shaped corner. The inner plane of the limiting plate 4 corresponds to the two side wall planes of the support ring 7 respectively, and a shock-absorbing pad is provided on the inner side of the limiting plate 4.

[0037] In this embodiment, the L-shaped limiting plate 4 with an arc at the corner can not only enable the support ring 7 to slide in contact with the inner wall of the limiting plate 4, but also will not affect the rotation of the support ring 7. At the same time, through the provision of the shock-absorbing pad, when the two side walls of the support ring 7 contact the limiting plate 4, a shock-absorbing effect is achieved, thereby achieving the purpose of protecting the support ring 7 and the mold ring 8.

An adjusting ring 92 is arranged inside the support groove 91. An adjusting gear 93 is arranged at the motor shaft of the switching motor. The outer wall of the adjusting ring 92 is provided with a tooth groove meshing with the adjusting gear 93.

[0041] In this embodiment, the support groove 91 is provided for installing the adjustment ring 92. The adjustment ring 92 can rotate inside the support groove 91 with the sliding rod 6 as the axis, and the adjustment ring 92 is provided with a rotational force by switching the motor and the adjustment gear 93. The side wall of the adjustment ring 92 is provided with a positioning groove. The support ring 7 is pushed to the position of the positioning groove by the hydraulic push rod 5, and then the support ring 7 is driven to deflect by the rotation of the adjustment ring 92, so as to achieve the effect of controlling the position of the mold ring 8.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model.
