Description

Technical Field

[0001] This utility model relates to the field of polymer material processing equipment technology, and in particular to a bio-based material steam molding foaming machine. Background Technology

[0002] A bio-based material steam molding foaming machine is a specialized piece of equipment used to heat, melt, bond, and finally mold bio-based foam particles into lightweight porous materials with complex three-dimensional shapes using high-temperature steam. Steam molding foaming technology is a key process in the production of bio-based materials. The process typically includes: mold closing, steam heating, molding foaming, cooling and shaping, and mold opening and part removal. Among these, the cooling and shaping stage is crucial to the final quality, shape stability, and production cycle of the product.

[0003] The current cooling method of bio-based material steam molding foaming machine is generally to open cooling water channels inside the mold and pump in cooling water to remove the heat from the mold. However, the existing cooling water channel design is relatively simple. The cooling water flows in from the inlet, flows along a fixed path and then flows out from the outlet. This directional flow method has certain defects. The temperature of the cooling water gradually increases during the flow process. As a result, the cooling effect is good and the temperature is low in the mold inlet area, while the outlet area is in contact with the already heat-absorbing warm water, resulting in poor cooling effect and high temperature. This makes it easy to form a significant temperature gradient inside the mold, which seriously affects the product yield. Utility Model Content

[0004] In view of this, the present invention provides a bio-based material steam molding foaming machine, the main technical problem to be solved is: the problem of uneven cooling caused by the fixed flow path of cooling water, which affects product quality.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a bio-based material steam molding foaming machine, comprising a base, a driving device fixedly connected to the front side of the base, a movable plate movably connected to the top of the base, a support fixedly connected to the top of the base, a fixed mold fixedly connected to the top of the support, a movable mold fixedly connected to the outer side of the support, cold water pipes fixedly connected to both sides of the fixed mold, each cold water pipe including a through pipe fixedly connected to both sides of the fixed mold, a fixed cylinder fixedly connected to the end of the through pipe away from the fixed mold, and a fixed cylinder fixed above the outer side of the fixed cylinder. The device is connected to an inlet water pipe, with an inlet pipe fixedly connected to the front side of the inlet water pipe. An outlet water pipe is fixedly connected to the lower outer side of the fixed cylinder. Lifting blocks are movably connected to the upper and lower sides of the inside of the fixed cylinder. The lifting blocks have through holes inside. A sealing sleeve is fixedly connected to the outer side of the lifting blocks. A connecting column is fixedly connected between the upper and lower lifting blocks. A connecting rod is fixedly connected to the lower part of the lower lifting block. A sliding column is fixedly connected to the lower end of the connecting rod. A sealing ring is fixedly connected to the lower part of the inside of the fixed cylinder. A support plate is fixedly connected to the outer side of the inlet water pipe and the outlet water pipe.

[0006] By adopting the above technical solution, cooling water is introduced into the inlet pipe during use, and then enters the fixed cylinder through the inlet water distribution pipe. Simultaneously, the reduction motor is started, causing the drive shaft to slowly rotate the turntable, which in turn slowly rotates the actuating column. The slow rotation of the actuating column, in turn, causes the fixed column to move the plate continuously left and right. When the plate moves to the left, it causes the left-side sliding column to rise, which in turn causes the left-side connecting rod to move both left-side lifting blocks upwards. This upward movement of the two left-side lifting blocks allows the through hole in the upper left-side lifting block to connect with the left end of the inlet water distribution pipe, while the sealing sleeve on the outside of the lower left-side lifting block seals the left-side outlet pipe. Simultaneously, the plate causes the right-side sliding column to descend, thereby... The connecting rod on the right side causes both lifting blocks on the right side to move downwards. This downward movement allows the through hole in the lower right lifting block to connect with the water outlet pipe. Meanwhile, the sealing sleeve on the outside of the upper right lifting block seals the right end of the inlet water distribution pipe, allowing cooling water to enter the left fixed cylinder through the through hole at the left end of the inlet water distribution pipe. Then, it enters the receiving cavity through the left pipe, then enters the right fixed cylinder through the right pipe, and finally exits through the right outlet pipe. This allows the cooling water in the receiving cavity to flow from left to right. When the plate moves to a certain position on the right, the cooling water will flow from right to left, continuously changing the direction of the cooling water flow for more uniform cooling and ensuring better product quality.

[0007] As a further description of the above technical solution: the base includes a seat body, and the top of the seat body is provided with a movable groove.

[0008] By adopting the above technical solution, the moving groove is used for the movement of the slider.

[0009] As a further description of the above technical solution: the driving device includes a fixed plate fixedly connected to the front side of the base, a reduction motor fixedly connected to the top of the fixed plate, a drive shaft fixedly connected to the output end of the reduction motor, a turntable fixedly connected to the rear end of the drive shaft, and a toggle post fixedly connected to the rear side of the turntable.

[0010] By adopting the above technical solution, starting the reduction motor enables the drive shaft to drive the turntable to rotate slowly, which in turn drives the actuating column to rotate slowly. The slow rotation of the actuating column enables the actuating column to move up and down in the column groove, while driving the fixed column to continuously move the plate left and right.

[0011] As a further description of the above technical solution: the movable plate includes a slide bar movably connected to the top of the base, the top of the slide bar is fixedly connected to a plate body, both sides of the top of the plate body are provided with slide grooves, the front side of the plate body is fixedly connected to a fixed column, and the interior of the fixed column is provided with a column groove.

[0012] By adopting the above technical solution, the slide groove is used for the movement of the slide column, and the column groove is used for the rotation and movement of the column.

[0013] As a further description of the above technical solution: the bracket includes a support column fixedly connected to the top of the base, a base plate fixedly connected to the top of the support column, a guide hole provided inside the base plate, a guide post fixedly connected to the top of the base plate, and a top plate fixedly connected to the top of the guide post.

[0014] By adopting the above technical solution, the connecting rod can be raised and lowered in the base plate, the guide hole is used to guide the raising and lowering of the connecting rod, and the guide column is used to guide the raising and lowering of the lifting plate.

[0015] As a further description of the above technical solution: the moving mold includes a lifting plate movably connected to the outside of the bracket, a hydraulic telescopic rod is fixedly connected to the top of the lifting plate, a sealing gasket is fixedly connected to the lower part of the lifting plate, an outer shell is fixedly connected to the middle of the lower part of the lifting plate, a fixing block is fixedly connected to the inner side of the outer shell, a connecting block is fixedly connected to the inner side of the fixing block, micro-holes are provided on the outer periphery and lower part of the hydraulic telescopic rod, and an air inlet pipe is fixedly connected to the top of the outer shell.

[0016] By adopting the above technical solution, the sealing gasket is made of silicone rubber to ensure the sealing between the fixed seat and the lifting plate. The air inlet pipe is connected to the steam source to allow steam to enter between the outer shell and the connecting block, and enter the fixed seat through micropores.

[0017] As a further description of the above technical solution: the fixed mold includes a fixed seat fixedly connected to the top of the bracket, the fixed seat has an internal receiving cavity, and both sides of the fixed seat have connecting holes.

[0018] By adopting the above technical solution, the receiving cavity is used to hold cooling water, and the connecting hole is used to fix the pipe.

[0019] As a further description of the above technical solution: the slide is set at an angle.

[0020] By adopting the above technical solution, the left slide rail is inclined to the lower left and the right slide rail is inclined to the lower right, and the left and right slide rails are symmetrically arranged. When the plate moves to the left, it can drive the left slide column to rise and the right slide column to fall. When it moves to the right, it can drive the left slide column to fall and the right slide column to rise.

[0021] By employing the above technical solution, the bio-based material steam molding foaming machine of this utility model has at least the following beneficial effects:

[0022] Compared with existing technologies, this bio-based material steam molding foaming machine, equipped with a drive device, a moving plate, and cold water pipes, facilitates uniform cooling of the product. Activating the reduction motor causes the actuating column to continuously move the plate left and right. This continuous movement of the plate causes the sliding columns on both sides to rise and fall, which in turn drives the connecting rod to continuously raise and lower the lifting blocks on both sides. This allows the flow direction of the cooling water to be constantly changed, facilitating uniform cooling and ensuring better product quality. Attached Figure Description

[0032] Reference Figure 1-7This utility model provides a bio-based material steam molding foaming machine, comprising a base 1, a drive device 2 fixedly connected to the front side of the base 1, a movable plate 3 movably connected to the top of the base 1, a support 5 fixedly connected to the top of the base 1, a fixed mold 7 fixedly connected to the top of the support 5, a movable mold 6 fixedly connected to the outer side of the support 5, cold water pipes 4 fixedly connected to both sides of the fixed mold 7, the cold water pipes 4 including through pipes 403 fixedly connected to both sides of the fixed mold 7, the through pipes 403 being fixed in the connecting holes 703 and communicating with the receiving cavity 702, a fixed cylinder 402 fixedly connected to the end of the through pipes 403 away from the fixed mold 7, and an inlet water flow pipe 404 fixedly connected to the upper outer side of the fixed cylinder 402. The two ends are connected to the fixed cylinders 402 on both sides. A water inlet pipe 405 is fixedly connected to the front of the water inlet pipe 404, used to introduce cooling water. A water outlet pipe 408 is fixedly connected to the lower outer side of the fixed cylinder 402, communicating with the fixed cylinder 402 to discharge the cooling water after use. Lifting blocks 409 are movably connected to the upper and lower sides inside the fixed cylinder 402. The lifting blocks 409 can move up and down inside the fixed cylinder 402. The lifting blocks 409 have a through hole 411 inside, which is L-shaped. One end of the through hole 411 communicates with the water outlet pipe 408 and the water inlet pipe 404, and the other end communicates with the inside of the fixed cylinder 402. A water outlet pipe 405 is fixedly connected to the outer side of the lifting block 409. A sealing sleeve 410, made of rubber, is used to ensure better sealing between the lifting block 409 and the fixed cylinder 402. A connecting column 412 is fixedly connected between the upper and lower lifting blocks 409. A connecting rod 406 is fixedly connected to the lower part of the lower lifting block 409. The connecting rod 406 can move up and down inside the fixed cylinder 402. A sliding column 407 is fixedly connected to the lower end of the connecting rod 406. The sliding column 407 can move in the sliding groove 302. A sealing ring 413, made of rubber, is fixedly connected to the lower part inside the fixed cylinder 402 to ensure better sealing between the connecting rod 406 and the fixed cylinder 402. A support plate is fixedly connected to the outside of the inlet water pipe 404 and the outlet water pipe 408. 401, the support plate 401 is fixedly connected to the base plate 501, and is used to support the inlet water distribution pipe 404 and the outlet water pipe 408. In use, cooling water is introduced into the inlet water pipe 405, and then enters the fixed cylinder 402 through the inlet water distribution pipe 404. At the same time, the reduction motor 203 is started, which causes the drive shaft 202 to drive the turntable 205 to rotate slowly, which in turn drives the actuating column 204 to rotate slowly. The slow rotation of the actuating column 204 drives the fixed column 303, which causes the plate 301 to move left and right continuously. When the plate 301 moves to the left, the plate 301 can drive the sliding column 407 on the left to rise, which in turn drives the connecting rod 406 on the left to move the two lifting blocks 409 on the left upward.By moving both lifting blocks 409 on the left upwards, the through hole 411 in the upper left lifting block 409 can connect with the left end of the water inlet pipe 404, while the sealing sleeve 410 on the outside of the lower left lifting block 409 will seal the water outlet pipe 408 on the left. Simultaneously, the plate 301 can drive the sliding column 407 on the right to descend, thereby driving the connecting rod 406 on the right to move both lifting blocks 409 on the right downwards. This downward movement of the two lifting blocks 409 on the right allows the through hole 411 in the lower right lifting block 409 to connect with the water outlet pipe 408, while the sealing sleeve 410 on the outside of the upper right lifting block 409 will seal the water outlet pipe 408 on the left. The sealing sleeve 410 seals the right end of the inlet water distribution pipe 404, allowing cooling water to enter the left-side fixed cylinder 402 through the through hole 411 at the left end of the inlet water distribution pipe 404, then enter the receiving cavity 702 through the left-side through pipe 403, and finally exit through the right-side outlet pipe 408. This allows the cooling water in the receiving cavity 702 to flow from left to right. When the plate 301 moves to a certain position to the right, the cooling water will flow from right to left, continuously changing the flow direction of the cooling water for more uniform cooling and better product quality.

[0033] Furthermore, the base 1 includes a seat body 101, and the top of the seat body 101 is provided with a moving groove 102 for the movement of the slider 305.

[0034] Furthermore, the drive device 2 includes a fixed plate 201 fixedly connected to the front side of the base 1. A reduction motor 203 is fixedly connected to the top of the fixed plate 201. A drive shaft 202 is fixedly connected to the output end of the reduction motor 203. A turntable 205 is fixedly connected to the rear end of the drive shaft 202. A toggle post 204 is fixedly connected to the rear side of the turntable 205. The toggle post 204 can move in the post groove 304. When the reduction motor 203 is started, the drive shaft 202 can drive the turntable 205 to rotate slowly, which in turn drives the toggle post 204 to rotate slowly. The slow rotation of the toggle post 204 allows the toggle post 204 to move up and down in the post groove 304, while also driving the fixed post 303 so that the plate 301 can move left and right continuously.

[0035] Furthermore, the movable plate 3 includes a slide bar 305 movably connected to the top of the base 1. The top of the slide bar 305 is fixedly connected to the plate body 301. Both sides of the top of the plate body 301 are provided with slide grooves 302. The slide grooves 302 are used for the movement of the slide column 407. The front side of the plate body 301 is fixedly connected to a fixed column 303. The fixed column 303 is provided with a column groove 304 inside. The column groove 304 is used to rotate and move the column 204.

[0036] Furthermore, the support 5 includes a support column 503 fixedly connected to the top of the base 1. A base plate 501 is fixedly connected to the top of the support column 503. A guide hole 502 is provided inside the base plate 501. The connecting rod 406 can be raised and lowered in the base plate 501. The guide hole 502 is used to guide the raising and lowering of the connecting rod 406. A guide column 504 is fixedly connected to the top of the base plate 501. The guide column 504 is used to guide the raising and lowering of the lifting plate 602. A top plate 505 is fixedly connected to the top of the guide column 504. The top plate 505 is fixedly connected to the hydraulic telescopic rod 601.

[0037] Furthermore, the moving mold 6 includes a lifting plate 602 movably connected to the outside of the bracket 5. The lifting plate 602 can be raised and lowered outside the guide column 504. A hydraulic telescopic rod 601 is fixedly connected to the top of the lifting plate 602, and a sealing gasket 603 is fixedly connected to the lower part of the lifting plate 602. The sealing gasket 603 is made of silicone rubber and is used to ensure the sealing between the fixed seat 701 and the lifting plate 602. A housing 604 is fixedly connected to the middle of the lower part of the lifting plate 602. A fixing block 605 is fixedly connected to the inner side of the housing 604, and a connecting block 607 is fixedly connected to the inner side of the fixing block 605. Microholes 606 are provided on the outer periphery and lower part of the hydraulic telescopic rod 601. An air inlet pipe 608 is fixedly connected to the top of the housing 604. The air inlet pipe 608 is connected to a steam source and is used to introduce steam into the space between the housing 604 and the connecting block 607, and into the fixed seat 701 through the microholes 606.

[0038] Furthermore, the fixed mold 7 includes a fixed base 701 fixedly connected to the top of the bracket 5. The fixed base 701 has a receiving cavity 702 inside, which is used to receive cooling water. Both sides of the fixed base 701 are provided with connecting holes 703, which are used to fix the through pipe 403.

[0039] Furthermore, the slide 302 is set at an angle, with the left slide 302 tilting to the lower left and the right slide 302 tilting to the lower right. The left and right slides 302 are symmetrically arranged. When the plate 301 moves to the left, it can drive the left slide column 407 to rise and the right slide column 407 to fall. When it moves to the right, it can drive the left slide column 407 to fall and the right slide column 407 to rise.

[0040] Working principle: During use, the cured bio-based foam beads are placed into the fixed base 701. Then, the hydraulic telescopic rod 601 is activated, causing the lifting plate 602 to descend and firmly press against the fixed base 701. Steam is then introduced through the air inlet pipe 608 between the fixed base 701 and the outer shell 604. The steam penetrates the gaps between the particles, heating the foam beads to above their glass transition temperature, causing the particle surfaces to soften and expand again. The particles are then compressed and melted together, forming a single foam product. Cooling water is then introduced into the water inlet pipe 405 and then through the water inlet diversion pipe. 404 enters the fixed cylinder 402, and at the same time, the reduction motor 203 is started, so that the drive shaft 202 can drive the turntable 205 to rotate slowly, which in turn drives the actuating column 204 to rotate slowly. The slow rotation of the actuating column 204 drives the fixed column 303, so that the plate 301 can move left and right continuously. When the plate 301 moves to the left, the plate 301 can drive the left sliding column 407 to rise, which in turn drives the left connecting rod 406 to move the two lifting blocks 409 on the left upward. By making the two lifting blocks 409 on the left move upward, the lifting block 40 on the upper left is lifted. The through hole 411 in section 9 can connect to the left end of the inlet water pipe 404, while the sealing sleeve 410 on the outside of the lower left lifting block 409 will seal the left outlet water pipe 408. At the same time, the plate 301 can drive the right sliding column 407 to descend, thereby driving the right connecting rod 406 to move both right lifting blocks 409 downward. By moving both right lifting blocks 409 downward, the through hole 411 in the lower right lifting block 409 can connect to the outlet water pipe 408, while the sealing sleeve 410 on the outside of the upper right lifting block 409 will seal the left outlet water pipe 408. The right end of 4 is closed, allowing cooling water to enter the left fixed cylinder 402 through the through hole 411 from the left end of the inlet diversion pipe 404, then enter the receiving cavity 702 through the left through pipe 403, then enter the right fixed cylinder 402 through the right through pipe 403, and finally exit through the right outlet pipe 408. This allows the cooling water in the receiving cavity 702 to flow from left to right. When the plate 301 moves to a certain position to the right, the cooling water will flow from right to left, which can continuously change the flow direction of the cooling water, making it easier to cool evenly and ensuring better product quality.
