Description

Technical Field

[0001] The invention relates to the field of casting molding, in particular to a steel strip corrugated pipe joint mold. Background Art

[0002] Steel strip corrugated pipe joints are usually composed of steel strip corrugated pipes and flanges at both ends. During the production of steel strip corrugated pipe joints, sand casting molds are required to cast the flanges. When using the sand casting mold, the molding sand and the pouring port mold core need to be placed in the upper sand box, and the molding sand is compacted in the upper sand box using hydraulic pressure. The pouring port mold core is then pulled out to form a pouring port on the molding sand. The molding sand and the flange mold core are then placed in the lower sand box, and the molding sand is compacted in the lower sand box using hydraulic pressure. The flange mold core is then pulled out to form a flange-shaped mold cavity on the molding sand. The upper and lower sand boxes are then combined to start casting. This process replaces the process of workers manually compacting the molding sand, effectively achieving the purpose of intelligent casting.

At the same time, the bolt is loosened to disengage it from the positioning hole at the edge of the I-shaped strip. Then the shifting frame can be adjusted to a position aligned with the adaption wheel to change the frequency of the adaption wheel being shifted, thereby changing the vibration frequency, so as to adapt to the friction between different types of molding sand and the flange mold core for demoulding to meet its usage requirements.

The door frame 6 is slidably mounted on the outer surface of the upper guide rod 8, and the end of the T-shaped frame 7 is fixed to the special-shaped frame 35. The molding sand is spread in the sand bucket 2, and then the casting sand box 4 is placed on the sand bucket 2. At this time, the corner block 3 is engaged with the edge of the casting sand box 4 to align the casting sand box 4 and the sand bucket 2 , then the upper hydraulic cylinder 9 drives the T-shaped frame 7 to move downward, and then drives the forming plate 5 and the flange mold core 11 to move downward, so that the forming plate 5 can be pressed on the casting sand box 4, and then the lower hydraulic cylinder 13 drives the sand pressing plate 12 to move upward to push the molding sand into the casting sand box 4, and under the extrusion of the sand pressing plate 12 and the molding plate 5, the molding sand is compacted in the casting sand box 4, and at the same time, the flange mold core 11 is wrapped by the compacted molding sand to form a flange-shaped mold cavity on the compacted molding sand, and then the flange mold core 11 is pulled out, and then the upper sand box with the pouring port is covered on the lower sand box, that is, the casting sand box 4, and it can be used. Because the production of the upper sand box is an existing technology and has been widely used, it is not elaborated here and is not shown in the figure.

[0030] The vibrating member includes a hexagonal rod 20 elastically mounted at the front edge of the upper end of the special-shaped frame 35. A plurality of knock claws 24 are arranged in a circular array at the lower end of the hexagonal rod 20. The hexagonal rod 20 serves to support the knock claws 24. A knock plate 27 is coaxially inlaid at the upper edge of the outer surface of the threaded sleeve 26. The knock claw 24 is pressed on the knock plate 27, and the knock claw 24 plays the role of striking the knock plate 27. An adapting wheel 23 is installed at the lower end of the hexagonal rod 20. The adapting wheel 23 and the knock claw 24 are staggered. A reducing shaft 37 is rotatably mounted on the upper side of the special-shaped frame 35. A plurality of shifting frames 39 are arranged in a circular array at the edge of the outer surface of the reducing shaft 37. The reducing shaft 37 serves to support the shifting frames 39. A dial wheel 42 is mounted at the ends of the plurality of dialing frames 39. The dial wheels 42 serve to support the dial wheels 42. One of the dial wheels 42 is in contact with the adaptation wheel 23. The servo motor 44 drives the dial wheel 42 on the reducing shaft 37 to rotate so as to continuously shift the adaptation wheel 23.

[0031] A servo motor 44 is fixedly installed at the rear end of the upper end of the special-shaped frame 35, and the output end of the servo motor 44 is fixed to the reducing shaft 37. The No. 1 transmission shaft 34 and the No. 2 transmission shaft 36 are rotatably installed on the lower side of the special-shaped frame 35. The No. 1 transmission shaft 34 is located behind the No. 2 transmission shaft 36. The No. 1 transmission shaft 34 and the No. 2 transmission shaft 36 play a transmission role. The upper end of the No. 1 transmission shaft 34 and the outer surface of the reducing shaft 37 near the middle are coaxially inlaid with a bevel gear 43. The two bevel gears 43 are engaged with each other, and the bevel gear 43 plays the role of connecting the reducing shaft 37 and the No. 1 transmission shaft 34 together.

[0032] The outer surface of the threaded sleeve 26 is coaxially inlaid with a large pulley 28 near the bottom of the knocking plate 27, the outer surface of the No. 2 transmission shaft 36 is coaxially inlaid with a small pulley 30, and a synchronous belt 29 is connected between the small pulley 30 and the No. 1 large pulley 28. The outer surface of the No. 2 transmission shaft 36 is coaxially inlaid with the No. 2 large pulley 31 near the top of the No. 1 small pulley 30, and the outer surface of the No. 1 transmission shaft 34 is coaxially inlaid with the No. 2 small pulley 33. The cooperation between the No. 1 small pulley 30 and the No. 1 large pulley 28 and the cooperation between the No. 2 small pulley 33 and the No. 2 large pulley 31 can make the threaded sleeve 26 rotate slowly, and then the core-stripping screw 25 slowly move up.

[0033] The outer surface of the hexagonal rod 20 is slidably mounted with a spring seat 21, which serves to compress the knock spring 22. The end of the spring seat 21 is rotatably mounted with an adjusting screw 19. The outer surface of the adjusting screw 19 is tightened with a stand 17. The lower end of the stand 17 is fixed to the special-shaped frame 35. The stand 17 serves to carry the adjusting screw 19. A T-shaped slide 18 extends from the side of the stand 17. The spring seat 21 is slidably mounted on the outer surface of the T-shaped slide 18. The T-shaped slide 18 serves to guide the spring seat 21. The outer side of the hexagonal rod 20 is wrapped with a knock spring 22. 2. The upper end of the knocking spring 22 is fixed to the spring seat 21. The knocking spring 22 can push the hexagonal rod 20, so that the knocking claw 24 on the hexagonal rod 20 hits the knocking plate 27 to generate vibration. The lower end of the knocking spring 22 is fixed to the lower end of the hexagonal rod 20. Rotating the adjusting screw 19 can drive the spring seat 21 to move downward to press the knocking spring 22 to change the deformation of the knocking spring 22, and then change the vibration amplitude generated when the knocking spring 22 is pushed, so as to adapt to the friction between different types of molding sand and the flange core 11 for demolding.

[0034] A plurality of I-shaped bars 38 are extended in a circular array at the edge of the outer surface of the reducing shaft 37. The shifting frame 39 is slidably mounted on the outer surface of the I-shaped bar 38. The I-shaped bar 38 serves to guide the shifting frame 39. Two positioning holes 41 are respectively provided at the upper end of the I-shaped bar 38. Bolts 40 are tightened through the shifting frame 39.

At the same time, when the servo motor 44 is reversed to drive the flange mold core 11 to move down and reset, the bolt 40 can be loosened first to adjust the position of the I-shaped bar 38, so that the dial wheel 42 and the adapting wheel 23 on the shifting frame 39 are staggered, so that the servo motor 44 will not be hindered by the dial wheel 42 and the adapting wheel 23 when reversing.

[0035] During casting, the molding sand is spread in the sand hopper 2, and then the casting sand box 4 is placed on the sand hopper 2. At this time, the corner block 3 is engaged with the edge of the casting sand box 4 to align the casting sand box 4 and the sand hopper 2. Then the upper hydraulic cylinder 9 drives the T-shaped frame 7 to move down, and then drives the forming plate 5 and the flange mold core 11 to move down, so that the forming plate 5 can be pressed on the casting sand box 4. Then the lower hydraulic cylinder 13 drives the sand pressing plate 12 to move up to push the molding sand into the casting sand box 4 and squeeze the sand between the sand pressing plate 12 and the forming plate 5. The molding sand is compacted in the casting sand box 4, and the flange mold core 11 is wrapped by the compacted molding sand to form a flange-shaped mold cavity on the compacted molding sand. Then the servo motor 44 drives the threaded sleeve 26 to rotate slowly, and then drives the tightened core-removing screw 25 to move up slowly, so that the flange mold core 11 on the forming plate 5 moves vertically upward to slowly separate from the molding sand. During this process, the top sand column 15 will always press against the upper end of the core in the mounting hole of the flange mold core 11 to exert pressure on the core. A certain thrust is applied to reduce the force exerted by the flange mold core 11 on the core during upward movement, so that the core gradually leaves the mounting hole of the flange mold core 11 and avoids the core from breaking. During this process, the servo motor 44 also drives the thumbwheel 42 on the different-diameter shaft 37 to rotate, so as to continuously turn the adapting wheel 23, so that the hexagonal rod 20 moves upward and drives the knocking spring 22 to deform. When the thumbwheel 42 turns away from the adapting wheel 23, the knocking spring 22 will restore its deformation to push the hexagonal rod 20. , so that the knocking claw 24 hits the knocking plate 27 vertically to generate vibration. At this time, the vibration is transmitted to the flange mold core 11 through the threaded sleeve 26 and the core-removing screw 25, so as to drive the flange mold core 11 to vibrate slightly, so as to reduce the friction and adsorption force between the flange mold core 11 and the molding sand, so as to further avoid the core breakage. When the flange mold core 11 is completely separated from the molding sand, the upper hydraulic cylinder 9 works to drive the forming plate 5 and the flange mold core 11 to reset, thereby completing the casting shape.
