Description

Technical Field

[0001] This utility model relates to the field of shoe sole production technology, specifically to an automatic open-type shoe sole production molding structure. Background Technology

[0002] The sole can include all the materials that make up the bottom, such as the outsole, midsole and heel. Generally, the common characteristics of sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, elastic, easy to fit the foot shape, not easy to deform after shaping, heat-insulating, and easy to absorb moisture. At the same time, it should work with the midsole to provide braking effect when changing feet to prevent slipping and to make it easy to stop.

[0003] During the production of shoe soles, molds are used for hot pressing and shaping. After the shoe soles are hot pressed and shaped, the molds need to be opened. Traditionally, shoe sole mold opening is mostly done manually. However, manual mold opening not only reduces the overall automation level of the shoe sole hot pressing machine, but also poses a production risk of burns to personnel, resulting in insufficient processing safety and certain production safety hazards. Therefore, this utility model proposes an automatic mold opening structure for shoe sole production. Utility Model Content

[0004] The purpose of this invention is to provide an automatic open-type shoe sole production molding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic mold-forming structure for shoe sole production, comprising a lower sole plate, linear guide rails fixedly installed on both sides of the upper surface of the lower sole plate, sliders slidably connected to both linear guide rails, a fixing plate fixedly installed on the upper surface of the sliders, a lower mold base disposed between the upper surfaces of the two fixing plates, a forming bottom mold fixedly installed on the upper surface of the lower mold base, a forming template rotatably connected to one side of the upper surface of the forming bottom mold via a rotating shaft, a roller rollingly installed on one side of the outer wall of the forming template, a cylinder seat fixedly installed on the outer surface of the lower sole plate and located on the side of the lower mold base, a mold-opening cylinder fixedly installed on the lower surface of the bottom end of the cylinder seat, an upper top plate fixedly installed on the top end of the output rod of the mold-opening cylinder, a top mold wedge fixedly installed on the upper surface of the upper top plate by bolts, the upper surface of the top mold wedge having a sloping structure design, and the upper surface of the top mold wedge in rolling contact with the rollers.

[0006] Preferably, a plurality of equally spaced linearly distributed buffer springs are fixedly installed on the upper surfaces of both fixing plates.

[0007] Preferably, the lower surface of the lower mold base is provided with a buffer groove adapted to the buffer spring, and the top part of the buffer spring is placed in the buffer groove and fixedly connected to the inner wall of the buffer groove.

[0008] Preferably, a guide rod is fixedly installed on the lower surface of the upper top plate, the guide rod passes through the cylinder seat, and the guide rod is slidably connected to the cylinder seat.

[0009] Preferably, a cross joint plate is fixedly installed between the top ends of the two fixed plates.

[0010] Preferably, a pusher cylinder is fixedly installed between the two linear guides and on the upper surface of the lower base plate, and the top end of the pusher rod of the pusher cylinder is fixedly connected to the cross plate.

[0011] Preferably, support columns are fixedly installed at the four corners of the upper surface of the lower base plate, and an upper fixing seat is fixedly installed between the tops of the four support columns.

[0012] Preferably, a downward pressing cylinder is fixedly installed at the center of the upper surface of the upper fixed seat, and an upper mold base is fixedly installed at the bottom end of the output rod of the downward pressing cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The shoe sole molding structure of this utility model, through the cooperation between the mold opening cylinder and the top mold wedge, can complete the automated mold opening work of the molding template in the actual production process. It has the effect of automatic mold opening by the top, which can effectively improve the automated mold opening production effect of the molding structure of this utility model. At the same time, the automatic mold opening method can replace the traditional manual mold opening, thereby effectively avoiding the risk of burns caused by manual mold opening, improving the safety of hot pressing molding of shoe soles, reducing production safety hazards, and better protecting operators. It is more practical and safer.

[0015] Meanwhile, this utility model provides a buffer spring at the bottom of the lower mold base. When the upper mold base is pressed down to close the mold, the upper forming mold installed on the lower mold base comes into contact with the forming template on the lower mold base. At this time, the pressure of closing the mold will compress several buffer springs at the bottom of the lower mold base, causing the lower mold base to sink a certain distance. In this way, the compressed buffer spring can elastically buffer a part of the pressure, thus effectively playing a certain buffering protection role when the mold is closed, avoiding damage caused by hard contact between the mold bases, better buffering protection for the mold and mold base, and improving service life.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-5This utility model provides an embodiment of an automatic open-mold shoe sole production molding structure, comprising a lower sole plate 1, linear guide rails 2 fixedly mounted on both sides of the upper surface of the lower sole plate 1, sliders 3 slidably connected to each of the two linear guide rails 2, fixing plates 4 fixedly mounted on the upper surface of the sliders 3, a lower mold base 6 disposed between the upper surfaces of the two fixing plates 4, a molding bottom mold 7 fixedly mounted on the upper surface of the lower mold base 6, and a molding template 8 rotatably connected to one side of the upper surface of the molding bottom mold 7 via a rotating shaft, as shown in the attached specification. Figure 2 As shown, the inner cavity of the molding template 8 is used for pressing and molding the shoe sole;

[0026] In order to automate the mold opening process of the molding template 7, a roller 9 is rolled on one side of the outer wall of the molding template 8. A cylinder seat 10 is fixedly installed on the outer surface of the lower base plate 1 and on the side of the lower mold base 6. A mold opening cylinder 11 is fixedly installed on the lower surface of the bottom end of the cylinder seat 10. An upper top plate 12 is fixedly installed on the top of the output rod of the mold opening cylinder 11. A top mold wedge 13 is fixedly installed on the upper surface of the upper top plate 12 by bolts. The upper surface of the top mold wedge 13 has a sloping structure design, and the upper surface of the top mold wedge 13 rolls in contact with the roller 9.

[0027] For details regarding this structural design, please refer to the appendix of the instruction manual. Figure 2 , Figure 3 as well as Figure 5 As shown, when automatic mold opening of the molding template 8 is required, the mold opening cylinder 11 can be used. When the mold opening cylinder 11 is working, its output rod is extended. When the output rod of the mold opening cylinder 11 is extended, it will drive the top plate 12 and the top mold wedge 13 to move upward. When the top mold wedge 13 moves upward, it will push the molding template 8 through the roller 9. When the molding template 8 is subjected to an upward pushing force, the molding template 8 can rotate and open along the rotation connection point between it and the molding bottom mold 7. In this way, the molding template 8 can be automatically pushed open, which has the practical effect of automatic mold opening.

[0028] When the mold opening cylinder 11 drives its output rod to retract, the top mold wedge 13 descends. As the top mold wedge 13 descends, the forming template 8 can rotate in reverse under gravity to close the mold. This allows the forming template 8 to close with the forming bottom mold 7 under gravity during the descent of the top mold wedge 13. The specific mold closing state is shown in the attached instruction manual. Figure 2 As shown.

[0029] In this embodiment, in order to provide displacement guidance for the upper and lower cylinder drive displacement of the upper top plate 12, please refer to the appendix of the specification for details. Figure 5As shown, a guide rod 14 is fixedly installed on the lower surface of the upper top plate 12. The guide rod 14 passes through the cylinder seat 10 and is slidably connected to the cylinder seat 10. Thus, the guide rod 14 can provide a certain linear displacement guidance for the vertical displacement of the upper top plate 12, ensuring the linear effect of its displacement and improving the displacement accuracy.

[0030] In this embodiment, in order to cooperate with the lower mold base 6 for closed hot pressing molding, support columns 17 are fixedly installed at the four corners of the upper surface of the lower base plate 1, and an upper fixed seat 18 is fixedly installed between the tops of the four support columns 17. A lower pressing cylinder 19 is fixedly installed at the center of the upper surface of the upper fixed seat 18, and an upper mold base 20 is fixedly installed at the bottom of the output rod of the lower pressing cylinder 19.

[0031] In practical use, this structural design allows the lower surface of the upper mold base 20 to be fitted with a molding upper mold that is compatible with the molding template 8. The upper mold base 20 and the molding upper mold of the shoe sole can be driven to descend by the set pressing cylinder 19. The descent of the upper mold base 20 and the molding upper mold of the shoe sole can be used to perform a pressing mold closing process with the molding template 8 below, which facilitates hot pressing molding.

[0032] Both the upper mold base 20 and the lower mold base 6 are equipped with steam channels, through which high-temperature steam can be introduced to heat the upper mold base 20 and the lower mold base 6 at high temperatures, thus meeting the high-temperature conditions for hot pressing of shoe soles.

[0033] In this embodiment, in order to provide a certain amount of pressing and buffering for the lower mold base 6, please refer to the appendix of the instruction manual for details. Figure 4 As shown, several equally spaced linearly distributed buffer springs 5 ​​are fixedly installed on the upper surfaces of both fixed plates 4.

[0034] The lower surface of the lower mold base 6 is provided with a buffer groove that is compatible with the buffer spring 5. The top part of the buffer spring 5 is placed in the buffer groove and fixedly connected to the inner wall of the buffer groove.

[0035] With this structural design, when the upper mold base 20 presses down to close the mold, the upper forming mold installed on the lower mold base 20 comes into contact with the forming template 8 on the lower mold base 6. At this time, the pressure of closing the mold will compress several buffer springs 5 ​​at the bottom of the lower mold base 6, causing the lower mold base 6 to sink a certain distance. In this way, the compressed buffer springs 5 ​​can elastically buffer a part of the pressure, thereby effectively playing a certain buffering protection role when the mold is closed, avoiding damage caused by hard contact between the mold bases, better buffering protection of the mold and mold base, and improving service life.

[0036] In this embodiment, in order to drive the feeding and discharging of the lower mold base 6, a horizontal connecting plate 15 is fixedly installed between the top ends of the two fixed plates 4, and a pusher cylinder 16 is fixedly installed between the two linear guide rails 2 and on the upper surface of the lower base plate 1. The top end of the pusher rod of the pusher cylinder 16 is fixedly connected to the horizontal connecting plate 15.

[0037] This structural design allows the pusher rod to extend and retract via the pusher cylinder 16. When the pusher rod extends, it abuts against the top horizontal connecting plate 15, thereby moving the upper mold base 6. The extension of the pusher rod drives the upper mold base 6 to perform the material ejection process after pressing. See the attached instruction manual for detailed state diagrams. Figure 1 As shown;

[0038] When the push rod retracts, the upper mold base 6 performs a feeding displacement. At this time, the upper mold base 6 can be placed directly below the upper mold base 20 to complete the feeding operation.

[0039] Working principle: When in use, the lower surface of the upper mold base 20 can be fitted with a molding upper mold that is compatible with the molding template 8. The upper mold base 20 and the molding upper mold of the shoe sole can be driven to descend by the set pressing cylinder 19. The descent of the upper mold base 20 and the molding upper mold of the shoe sole can be pressed down to close the mold with the molding template 8 below, which facilitates the hot pressing molding process.

[0040] Both the upper mold base 20 and the lower mold base 6 are equipped with steam channels, through which high-temperature steam can be introduced to heat the upper mold base 20 and the lower mold base 6 at high temperatures, thus meeting the high-temperature conditions for hot pressing of shoe soles.

[0041] During the actual processing, the pusher rod can be extended and retracted by the pusher cylinder 16. When the pusher rod retracts, the upper mold base 6 will move to feed material. At this time, the upper mold base 6 can be placed directly below the upper mold base 20 to complete the feeding operation.

[0042] After the upper mold base 6 is fed, the upper mold base 20 and the upper mold of the shoe sole can be driven to descend by the set pressing cylinder 19. Thus, the descent of the upper mold base 20 and the upper mold of the shoe sole can be pressed down to close the mold with the lower molding template 8, thereby completing the hot pressing molding of the shoe sole.

[0043] When the upper mold base 20 is pressed down to close the mold, the upper forming mold installed on the lower mold base 20 comes into contact with the forming template 8 on the lower mold base 6. At this time, the pressure of closing the mold will compress several buffer springs 5 ​​at the bottom of the lower mold base 6, causing the lower mold base 6 to sink a certain distance. In this way, the compressed buffer springs 5 ​​can elastically buffer a part of the pressure, thus effectively playing a certain buffering protection role when the mold is closed, avoiding damage caused by hard contact between the mold bases, better buffering protection of the mold and the mold base, and improving service life.

[0044] After the molding process is completed, the upper mold base 20 rises and resets under the drive of the lower pressure cylinder 19, while the upper mold base 6 is pushed out by the pusher cylinder 16, thus completing the ejection and discharge of the upper mold base 6.

[0045] After the upper mold base 6 is pushed out, the molding template 8 is automatically opened. At this time, the mold opening cylinder 11 can work. When the mold opening cylinder 11 is working, it drives its output rod to extend. When the output rod of the mold opening cylinder 11 extends, it will drive the top plate 12 and the top mold wedge 13 to move upward. When the top mold wedge 13 moves upward, it will push the molding template 8 through the roller 9. When the molding template 8 is subjected to an upward pushing force, the molding template 8 can rotate and open along the rotation connection point between it and the molding bottom mold 7. In this way, the molding template 8 can be automatically pushed open, which has the actual effect of automatic mold opening. Then the molded shoe sole can be taken out.

[0046] When the mold opening cylinder 11 drives its output rod to retract, the top mold wedge 13 descends. As the top mold wedge 13 descends, the forming template 8 can rotate in reverse under gravity to close the mold. This allows the forming template 8 to close with the forming bottom mold 7 under gravity during the descent of the top mold wedge 13, completing the structural reset. The specific mold closing state is shown in the attached instruction manual. Figure 2 As shown.

[0047] The shoe sole molding structure of this utility model, through the cooperation between the mold opening cylinder 11 and the top mold wedge 13, can complete the automated mold opening work of the molding template 8 in the actual production process. It has the effect of automatic mold opening by pushing, which can effectively improve the automated mold opening production effect of the molding structure of this utility model. At the same time, the automatic mold opening method can replace the traditional manual mold opening, thereby effectively avoiding the risk of burns that exist in manual mold opening, improving the safety of hot pressing molding of shoe soles, reducing production safety hazards, and better protecting operators. It is more practical and safer.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
