Description

Technical Field

[0001] This application relates to the field of shoe sole production machinery, and in particular to a shoe sole forming mold and forming equipment. Background Technology

[0002] Currently, the common method in shoe sole production is to inject foamed raw material into a shoe sole molding mold, heat it after the mold is closed to make the foamed raw material foam to form the shoe sole, and then remove the shoe sole after the mold is opened.

[0003] For some shoe soles, the outsole needs to be wear-resistant and have a high hardness, while the insole needs to be softer to ensure user comfort. However, current shoe soles are made of a single material through foaming, resulting in a uniform sole hardness, which makes it difficult to meet the hardness requirements of the insole and outsole. Summary of the Invention

[0004] To better accommodate the different hardness requirements of the inner and outer surfaces of the shoe sole, this application provides a shoe sole molding mold and molding equipment.

[0005] Firstly, this application provides a shoe sole forming mold, which adopts the following technical solution:

[0006] A shoe sole forming mold includes a lower mold and an upper mold corresponding to the lower mold. The lower mold has a forming groove. Two partitions are horizontally slidably connected to the two opposite side walls of the forming groove. The two partitions are close to each other to separate the forming groove. The lower mold is provided with a driving component for driving the partitions to slide.

[0007] By adopting the above technical solution, during use, a foaming material with higher hardness after molding is poured into the molding tank below the partition, and a foaming material with lower hardness after molding is poured into the molding tank above the partition. Then, it is heated. After the foaming material is initially molded, the partition is slid away from the molding tank by the drive component, and then the upper and lower molding materials are brought closer to each other. Then, heating continues to fuse the two molding materials into a whole sole. The resulting sole has different hardness on the inner and outer surfaces, which is convenient to adapt to the different hardness requirements of the inner and outer surfaces of the sole. The partition is set to facilitate the separation of the upper and lower foaming materials.

[0008] Optionally, the lower mold has a slot for the partition to slide into, and the drive unit includes an air pump, the air pump outlet being used to communicate with the slot.

[0009] By adopting the above technical solution, the slot is convenient for storing the partition. When driving the partition to move, the air pump is turned on to inflate and de-inflate the slot, so that the partition moves under the action of air pressure. The driving component has a simple structure and is easy to operate.

[0010] Optionally, a support plate is slidably connected in the vertical direction within the forming groove, and a second driving component is provided on the lower mold for driving the support plate to slide.

[0011] By adopting the above technical solution, the second driving component can drive the support plate to move vertically, so that after the upper foam material and the lower foam material are initially formed, the partition is put into the slot. Then, the second driving component drives the support plate to move vertically, so that the lower molding material is close to the upper molding material. Then, the heating continues, so that the upper molding material and the lower molding material are fused into a whole insole.

[0012] Optionally, the second drive component includes a cylinder.

[0013] By adopting the above technical solution, when driving the carrier plate to move, cylinder one can be activated. The driving component has a simple structure and is easy to operate.

[0014] Optionally, ribs are fixedly connected to both the upper and lower surfaces of the partition, with the ribs on the upper surface of the partition and the ribs on the lower surface of the partition arranged vertically opposite each other.

[0015] By adopting the above technical solution, after the foamed raw material is initially formed, it is placed into a partition. The ribs on the partition allow for the creation of pre-reserved grooves after the molding material is formed. When the upper and lower molding materials are fused together into a whole, the foamed raw material is injected into the pre-reserved grooves, and then heating continues to fuse the upper and lower molding materials together with the newly added foamed material to form a whole insole. The ribs facilitate the creation of pre-reserved grooves after the molding material is formed, so that the foamed raw material can be injected later. After the injected foamed raw material is formed, it connects the upper and lower molding materials into a whole. In addition, due to the presence of the partition, if the upper and lower molding materials are brought close together, it will affect the thickness of the molded insole. However, after the foamed raw material is injected later, there is no need to move the lower molding material, which facilitates the production of insoles with standard thickness.

[0016] Optionally, a side strip is fixedly connected to the side wall of the rib.

[0017] By adopting the above technical solution, the stability of the connection between the upper and lower molding materials is enhanced.

[0018] Optionally, a support block is slidably connected vertically to both sides of the two partitions inside the lower mold. The lower mold is provided with a second cylinder for driving the support block to slide. The support block is provided with a compensation block. The side of the compensation block facing the molding groove is adapted to the inner wall of the molding groove. The support block moves vertically so that the compensation block is located between the slots and blocks the slots. The partition moves towards the molding groove to push the compensation block to move until the side of the compensation block away from the partition is flush with the inner wall of the molding groove. The compensation block has an injection hole communicating with the molding groove. The support block is provided with a spring for resetting the support block.

[0019] By adopting the above technical solution, after the partition is inserted into the slot, the second cylinder drives the bearing block to move upward until the compensation block is located in the slot. Then, the first drive unit drives the partition to move, pushing the compensation block to move until the side of the compensation block away from the partition is flush with the inner wall of the molding groove, thereby sealing the molding groove. When foaming material is injected into the reserved groove, it can prevent the foaming material from entering the slot, affecting the style of the shoe sole after molding, and reducing the need for subsequent insole repair. The spring facilitates the reset of the compensation block.

[0020] Optionally, a pattern one is formed on the inner wall of the forming groove, and a pattern two is formed on the side of the two compensation blocks that are close to each other. The pattern one and the pattern two are matched to form the pattern of the shoe sole sidewall.

[0021] By adopting the above technical solution, for insoles with pattern requirements on the sidewall, since the side of the compensation block away from the partition is flush with the inner wall of the molding groove, it is easy for pattern one and pattern two to form the overall pattern of the insole sidewall.

[0022] Secondly, the shoe sole forming equipment provided in this application adopts the following technical solution:

[0023] A shoe sole forming device includes a shoe sole forming mold and a frame. The upper mold is slidably connected to the frame in a vertical direction, and the lower mold is fixed to the frame. The frame has a track along its length, and a feeding trolley is slidably connected to the track along its path. The feeding trolley has an upper liquid tank and a lower liquid tank. The forming tank is connected to an upper liquid branch pipe above a partition and a lower liquid branch pipe below the partition. The upper liquid tank is connected to an upper liquid outlet pipe, and the lower liquid tank is connected to a lower liquid outlet pipe. The feeding trolley moves to connect the upper liquid outlet pipe and the upper liquid branch pipe, and the lower liquid outlet pipe and the lower liquid branch pipe.

[0024] By adopting the above technical solution, when injecting foaming raw materials into the molding tank, the feeding trolley is moved so that the upper liquid outlet pipe and the upper liquid branch pipe are aligned, and the lower liquid outlet pipe and the lower liquid branch pipe are aligned, which facilitates the separate injection of foaming raw materials into the molding tank.

[0025] In summary, this application includes the following beneficial technical effects:

[0026] 1. This application uses a partition to separate the upper foam material and the lower foam material. After the upper and lower foam materials are initially formed, the partition is inserted into the slot, and the upper and lower pre-formed materials are then fused together to form an integral insole. The upper and lower foam materials have different hardnesses, which facilitates the production of soles with different hardnesses on the inner and outer surfaces, thus adapting to the different hardness requirements of the inner and outer surfaces of the sole.

[0027] 2. This application uses a feeding trolley on the molding equipment to facilitate the separate injection of foaming raw materials into the molding tank. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0040] This application discloses a shoe sole molding die. (Refer to...) Figure 1 and Figure 2 The device includes a lower mold 1 and an upper mold 2 corresponding to the lower mold 1. The lower mold 1 has two forming grooves 3, which are shaped like shoe soles. Two opposing partitions 4 are slidably connected to the side walls of the forming grooves 3. The lower mold 1 has slots 5 for the partitions 4 to slide. The sliding direction of the partitions 4 is set along the width direction of the forming grooves 3. The two partitions 4 are close to each other to divide the forming grooves 3 into an upper groove 6 and a lower groove 7. When the two partitions 4 abut against each other, the upper groove 6 and the lower groove 7 are not connected. The lower mold 1 is provided with a driving component for driving the partitions 4 to slide.

[0041] Reference Figure 2 and Figure 3 The slot 5 and the partition 4 are sealed. The drive unit includes an air pump 8, and the air outlet of the air pump 8 is connected to an air pipe 9, which is connected to the slot 5.

[0042] In another embodiment, the driving component can also be a lead screw drive component, which drives the partition 4 to slide by rotating the lead screw.

[0043] In this embodiment, during use, the partition 4 slides to divide the molding groove 3 into an upper groove 6 and a lower groove 7. Then, foaming material is injected into the upper groove 6 and the lower groove 7 respectively, and the hardness of the foaming material in the upper groove 6 after molding is greater than that of the foaming material in the lower groove 7 after molding. The foaming material is then heated to make it initially molded. The shoe sole components initially molded in the upper groove 6 and the shoe sole components initially molded in the lower groove 7 are then brought close together, and then heating is continued to fuse the two shoe sole components into a whole, forming shoe soles with different hardness.

[0044] In this embodiment, in order to facilitate the removal of the molded shoe sole, a support plate 10 is slidably connected in the lower groove 7 along the vertical direction. The outer wall of the support plate 10 is adapted to the inner wall of the molding groove 3. The lower mold 1 is provided with a second driving component for driving the support plate 10 to slide.

[0045] The second driving component includes a cylinder 11, which is fixedly connected inside the lower mold 1. The second cylinder 38 is vertically arranged and located below the lower groove 7. The output shaft of the second cylinder 38 passes through the lower groove 7 and is fixedly connected to the bearing plate 10.

[0046] Reference Figure 4 The partition 4 is provided with multiple sets of ribs 12. Each set of ribs 12 includes two ribs, and the two ribs 12 are symmetrically arranged on both sides of the thickness direction of the partition 4. Side strips 13 are fixedly connected to both sides of the length direction of the end of the rib 12 away from the partition 4.

[0047] Reference Figure 2 and Figure 3 After the sole components in the upper groove 6 and lower groove 7 are initially formed, the partition 4 is removed. Then, the sides of the sole components in the upper groove 6 and lower groove 7 that are close to each other will form a reserved groove. Then, foaming material is injected into the reserved groove. After the foaming material is formed, it connects the sole components in the upper groove 6 and lower groove 7 into a whole to form the sole, thereby improving the strength and quality of the sole.

[0048] To prevent the foaming material from flowing into the slot 5 when it is injected into the reserved slot, two blocking components are provided on the lower mold 1 below the partition 4. The blocking components include a support block 14 and a compensation block 15. The path direction of the support block 14 and the path direction of the compensation block 15 are set along part of the path direction of the molding groove 3. The support block 14 is inserted vertically into the lower mold 1. A vertically arranged cylinder 38 is fixedly connected inside the lower mold 1. The telescopic end of the cylinder 38 is fixedly connected to the lower surface of the support block 14. The side of the compensation block 15 facing the molding groove 3 is adapted to the inner wall of the molding groove 3. The two compensation blocks 15 move closer to each other to fill the gap left by the sliding of the partition 4. The support block 14 moves vertically so that the compensation block 15 is located between the slots 5 and blocks the slots 5. The partition 4 moves towards the molding groove 3 to push the compensation block 15 to move until the side of the compensation block 15 away from the partition 4 is flush with the inner wall of the molding groove 3.

[0049] To facilitate the reset of the compensation block 15, multiple mounting slots 19 are provided on the upper surface of the bearing block 14. A spring 16 is fixedly connected in the mounting slot 19, and the other end of the spring 16 is fixedly connected to the compensation block 15.

[0050] Reference Figure 5To facilitate the injection of liquid into the reserved slot, the compensation block 15 is provided with an injection hole 17 that connects to the forming slot 3, and the partition plate 4 is provided with a connecting hole 18. When the compensation block 15 is located in the slot 5, one end of the connecting hole 18 is used to connect to the injection hole 17, and the other end of the connecting hole 18 is used to connect to the outside. The partition plate 4 moves toward the compensation block 15 to connect the injection hole 17 and the connecting hole 18.

[0051] After the partition 4 is fully inserted into the slot 5, the bearing block 14 is moved by the cylinder 38 so that the compensation block 15 is located in the slot 5. Then, the partition 4 is moved by the drive component and the compensation block 15 is moved until the side of the compensation block 15 away from the partition 4 is flush with the inner wall of the molding groove 3. Then, the foaming material is injected into the molding groove 3 through the connecting hole 18 and the injection hole 17. Then, the heating continues to make the added foaming material foam, connecting the upper groove 6 and the lower preliminary molded shoe sole components into a whole, and forming the shoe sole in one piece.

[0052] In this embodiment, in order to ensure that the molded sole has a complete pattern, a pattern one is provided on the inner wall of the molding groove 3, and a pattern two is provided on the side of the two compensation blocks 15 that are close to each other. The pattern one and the pattern two are matched to form the pattern of the side wall of the sole.
