A T-shaped slot 5 is opened on the side wall of each clamping block 4, and a T-shaped block 6 for cooperating with the T-shaped slot 5 is fixed on the side wall of each mold block 3.

[0027] By cooperating with the provided T-slot 5 and the T-block 6, when installing the corresponding mold block 3, the T-block 6 is snapped into the T-slot 5, and the weight of the T-slot 5 and the mold block 3 is borne by the provided T-slot, avoiding the inconvenience of positioning and fixing the mold block 3 due to its heavy weight. When the side wall of the T-block 6 contacts the inner wall of the T-slot 5, the through hole is aligned with the threaded hole, completing the positioning of the T-block 6 and the mold block 3, and then the bolt 8 is threadedly tightened into the threaded hole to complete the fixation of the mold block 3, which is convenient for disassembly and assembly.

[0028] A translation mechanism is provided on the base 1 , and side mounting frames 7 are fixed on both sides of the base 1 , and each side mounting frame 7 is provided with a cleaning mechanism.

[0029] The upper and lower end faces of each engaging block 4 are provided with a through hole, and a bolt 8 is provided in each through hole. The threaded end of each bolt 8 is threadedly penetrated into the T-shaped block 6, and the upper and lower end faces of each T-shaped block 6 are provided with a threaded hole for matching with the bolt 8. Through the cooperation of the provided threaded hole and the through hole, the positioning of the T-shaped block 6 can be completed by only bringing the side wall of the T-shaped block 6 into contact with the inner wall of the T-shaped slot 5, which is easy to operate.

[0030] The translation mechanism includes two sunken grooves symmetrically opened on the upper end face of the base 1, and an electric push rod 10 is fixed to the inner bottom of each sunken groove, and a lower connecting ear 11 is fixed to the end of each electric push rod 10, and two upper connecting ears 12 are fixed to the bottom of each movable seat 9. Two connecting rods 13 are rotatably arranged between the two adjacent upper connecting ears 12 and the adjacent lower connecting ears 11. When it is necessary to replace mold blocks 3 with different inner diameters and cooperate to complete the production of corrugated pipes with different diameter specifications, in order to avoid motion interference between the two cooperating mold blocks 3, it is necessary to move the two movable seats 9 to both sides. In order to achieve this purpose, the telescopic end of the electric push rod 10 can be driven to extend, thereby pushing the lower connecting ear 11 to rise, thereby pushing the connecting rod 13, so that the connecting rod 13 pushes the upper connecting ear 12, so that the movable seat 9 moves sideways, and adjusts the spacing between the two movable seats 9 so that the two cooperating mold blocks 3 can rely on each other to shape the semi-finished corrugated pipes delivered, and has strong applicability.

[0031] A plurality of sliding seats 14 are fixed to the lower end surface of each mobile seat 9, and a plurality of sliding grooves 15 for cooperating with the sliding seats 14 are provided on the upper end surface of the base 1. A plurality of rotating wheels are rotatably provided at the bottom of each sliding seat 14. The cooperation between the sliding seats 14 and the sliding grooves 15 guides the movement of the mobile seat 9 to avoid deviation of the mobile seat 9 during the movement, which affects the use effect. The rotating wheels reduce the friction between the sliding seat 14 and the sliding grooves 15, so that the mobile seat 9 can be pushed to move by applying a smaller force.

[0032] The cleaning mechanism includes a connecting frame 16 movably arranged on the top of the side mounting frame 7, a roller mounting seat 17 is fixed on the side wall of the connecting frame 16, a roller body 18 is rotatably arranged in the roller mounting seat 17, a motor for driving the roller body 18 to rotate is provided in the roller mounting seat 17, a brush layer 19 is fixedly sleeved on the outer wall of the roller body 18, an air guide hood 20 is also fixed on one side of the connecting frame 16, an air pump for supplying air to the air guide hood 20 is provided in the base 1, and the air guide hood 20 is arc-shaped. When the mold block 3 completes the shaping of the bellows, it will rotate one circle with the transmission chain 2 and return to the working position again to clamp and shape the bellows. When the mold block 3 passes through the brush layer 19, the brush layer 19 Driven by the roller body 18, the brush layer 19 cleans the working surface of the mold block 3 to prevent part of the side wall of the corrugated tube from remaining and adhering to the working surface of the mold block 3 when the mold block 3 clamps and shapes the corrugated tube, thereby affecting the subsequent shaping of the corrugated tube. When the brush layer 19 contacts the working surface of the mold block 3, the working surface of the mold block 3 is cleaned. After the mold block 3 is cleaned by the brush layer 19, it will pass through the air guide cover 20. Since the air guide cover 20 is arc-shaped, the air guide cover 20 will spray air on the working surface of the mold block 3 when the mold block 3 passes through the air guide cover 20. On the one hand, the residue cleaned on the working surface of the mold block 3 is blown away, and on the other hand, the mold block 3 is cooled.

[0035] When the present invention is in use, through the cooperation of the provided T-slot 5 and the T-block 6, when the corresponding mold block 3 is installed, the T-block 6 is snapped into the T-slot 5, and the weight of the T-block 6 and the mold block 3 is borne by the provided T-slot 5, avoiding the inconvenience of positioning and installing the mold block 3 due to its heavy weight. When the side wall of the T-block 6 contacts the inner wall of the T-slot 5, the through hole is aligned with the threaded hole, and the positioning of the T-block 6 and the mold block 3 is completed. Then, the bolt 8 is threadedly tightened into the threaded hole to complete the fixation of the mold block 3. The assembly and disassembly are convenient, and the semi-finished corrugated pipe delivered can be clamped and shaped by the provided multiple mold blocks 3;

[0036] When it is necessary to replace the mold blocks 3 of different inner diameters to complete the production of corrugated pipes of different diameters, in order to avoid the motion interference of the two mold blocks 3 used in conjunction with each other, it is necessary to move the two movable seats 9 to the sides. In order to achieve this purpose, the telescopic end of the electric push rod 10 can be driven to extend, thereby pushing the lower connecting ear 11 to rise, thereby pushing the connecting rod 13, so that the connecting rod 13 pushes the upper connecting ear 12, so that the movable seat 9 moves to the side, and the spacing between the two movable seats 9 is adjusted, so that the two mold blocks 3 used in conjunction with each other can be used together to shape the semi-finished corrugated pipe delivered, which has strong applicability.

[0037] When the mold block 3 completes the shaping of the bellows, it will rotate one circle with the transmission chain 2 and return to the working position again to clamp and shape the bellows. When the mold block 3 passes through the brush layer 19, the brush layer 19 is driven by the roller body 18 to clean the working surface of the mold block 3 to prevent part of the side wall of the bellows from remaining and adhering to the working surface of the mold block 3 when the mold block 3 clamps and shapes the bellows, affecting the subsequent shaping of the bellows. When the brush layer 19 contacts the working surface of the mold block 3, the working surface of the mold block 3 is cleaned. When the mold block 3 is cleaned by the brush layer 19, it will pass through the air guide cover 20. Since the air guide cover 20 is arc-shaped, when the mold block 3 passes through the air guide cover 20, the air guide cover 20 sprays air on the working surface of the mold block 3. On the one hand, the residue cleaned on the working surface of the mold block 3 is blown away, and on the other hand, the mold block 3 is cooled.
