Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding equipment, and specifically, to an automatic mold shaking device for polyurethane foaming products. Background Art

[0002] The Chinese utility model patent with the publication number CN214725853U discloses a full-automatic track-type polyurethane foaming product production equipment, which includes a machine platform frame, a material tank unit and a material injection unit. A support frame and a material tank placement rack for installing the material tank unit are arranged inside the machine platform frame. A filter for filtering polyurethane foaming materials is arranged on the material tank placement rack, and the filter is communicated with the material tank unit. A mold rack is arranged on the machine platform frame, and a number of mold components are arranged in the mold rack. The material injection unit includes an extension bracket and a machine head component for injecting materials into the mold components. The machine head component is arranged at one end of the extension bracket, and the machine head component is connected with the material tank unit. The other end of the extension bracket is movably arranged at the top of the machine platform frame through a moving mechanism, and an exhaust and air extraction mechanism is arranged inside the machine platform frame. The machine head component of the above polyurethane foaming product production equipment moves back and forth to inject materials into multiple mold components. The forward and backward movement of the machine head component must be equipped with a driving mechanism to achieve, which has the disadvantages of complex structure and high cost; after a mold component is filled with materials and the mold is closed, an independent mold shaking device driven by a cylinder is used to shake the mold component. An independent mold shaking device is arranged for each mold component, and the structure of the equipment is more complex and the cost is also higher; the shaking angle of the mold shaking device driven by the cylinder is also limited to a relatively small angle range.

[0022] To further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail with reference to the attached drawings as follows:

[0023] Such as Figures 1 to 3As shown in the figure, an automatic mold rocking device for a polyurethane foaming product of the present utility model includes a machine body 1. On one side of the machine body 1, there is a guide rail 11. On the guide rail 11, there is a carriage 2 that can slide along the guide rail 11. At the lower end of the guide rail 11, there is a driving wheel 13 driven by a servo motor 12, and at the upper end of the guide rail 11, there is a driven wheel 14. There is a transmission member 15 on the guide rail 11. One end of the transmission member 15 is connected to the upper end of the carriage 2, and the other end of the transmission member 15 is connected to the lower end of the carriage 2. The lower turning part 151 of the transmission member 15 is in transmission connection with the driving wheel 13, and the upper turning part 152 of the transmission member 15 is in transmission connection with the driven wheel 14. A conveying frame 3, on which there is a conveying guide rail 31. A supporting frame 4, a plurality of supporting frames 4 are slidably connected to the conveying guide rail 31. On the supporting frame 4, there is a mold frame 5 pivotally connected and capable of rotating relative to the supporting frame 4. On both sides of the supporting frame 4, there are two upwardly extending supporting arms 41, and the mold frame 5 is pivotally connected to the supporting arms 41. A polyurethane forming mold 6 is placed on the mold frame 5. There is a clamping part on the carriage 2, and the mold frame 5 is correspondingly provided with a cylinder 51 extending outward and capable of sliding into the clamping part.

[0024] Further, both the driving wheel 13 and the driven wheel 14 are sprockets, the number of teeth of the driving wheel 13 and the driven wheel 14 is the same, the transmission member 15 is a chain, the chain is respectively meshed with the driving wheel 13 and the driven wheel 14, the number of driving wheels 13 is two, the number of driven wheels 14 is also two, and the number of chains is correspondingly two.

[0025] More specifically, the carriage 2 is provided with four pulleys 21, and the guide rail 11 is provided with four guide strips 16 that can be embedded with the pulleys. The four pulleys 21 are respectively slidably connected to the four guide strips 16. The four guide strips 16 are all in a "C" shape. The four pulleys 21 being respectively slidably connected to the four guide strips 16 can ensure the smoothness and low noise when the carriage 2 slides. The four guide strips 16 being all in a "C" shape can ensure that the relative distance between the carriage 2 and the mold frame 5 remains unchanged during the swinging process of the carriage 2 driving the mold frame 5, and ensure the reliability of mold rocking.

[0026] Among them, the clamping part is two spaced clamping strips 22, and the cylinder 51 of the mold frame 5 can slide into the gap between the two clamping strips 22.

[0027] In addition, there are two conveying guide rails 31, and the lower end of the supporting frame 4 is provided with two sliders 42 slidably connected to the conveying guide rails 31.

[0028] Specifically, there is a gearbox 17 between the servo motor 12 and the driving wheel 13. The rotating shaft of the servo motor 12 is connected to the input end of the gearbox 17, and the driving wheel 13 is fixed to the output end of the gearbox 17. The driven wheel 14 is pivotally connected to the upper end of the guide rail 11.

[0029] The working principle of the present utility model is as follows: When the support frame 4 is conveyed to be directly opposite to the guide rail 11, the column 51 of the mold base 5 slides into the gap between the two clamping strips 22 of the clamping part. After the mixing nozzle fills the polyurethane molding die on the mold base 5 with polyurethane material, the mold closes; the servo motor 12 starts to work. The rotation of the servo motor 12 drives the driving wheel 13 to rotate forward. The forward rotation of the driving wheel 13 drives the transmission part 15 to drive the carriage 2 to move downward. The downward movement of the carriage 2 drives the mold base 5 to swing downward through the two clamping strips 22. The downward swing of the mold base 5 will cause the polyurethane molding die 6 filled with polyurethane material to tilt downward by a certain angle. The downward tilt of the polyurethane molding die 6 by a certain angle will cause the polyurethane material to flow to one side of the polyurethane molding die 6; After swinging to the set angle and staying for the set time, the servo motor 12 works in reverse rotation again. The rotation of the servo motor 12 drives the driving wheel 13 to rotate in reverse. The reverse rotation of the driving wheel 13 drives the transmission part 15 to drive the carriage 2 to move upward. The upward movement of the carriage 2 drives the mold base 5 to swing upward through the two clamping strips 22. The upward swing of the mold base 5 will cause the polyurethane molding die 6 filled with polyurethane material to tilt upward by a certain angle. The upward tilt of the polyurethane molding die 6 by a certain angle will cause the polyurethane material to flow to the other side of the polyurethane molding die 6. Only by setting one mold rocking device, it can realize injecting polyurethane into multiple molds and rocking the molds. There is no need for the head assembly for feeding to move a large distance to inject polyurethane into each mold, which effectively simplifies the structure of the equipment and reduces costs, increases the product qualification rate and reduces waste products, thereby reducing material costs. The rocking action and stroke are stable, and the rocking speed can be changed by adjusting the rotation speed of the servo motor 12 according to the product characteristics, and the rocking angle can be changed by adjusting the number of rotation turns of the servo motor 12 according to the product characteristics. The rocking angle range is greatly expanded.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
