Description

Technical Field

[0001] This invention relates to the field of shoe sole processing technology, and in particular to a pressing equipment and process for soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes. Background Technology

[0002] In the processing of single-layer leather shoes, the sole positioning and pressing equipment and process are key to ensuring a firm bond between the sole and the upper and improving the quality of the finished shoes. The sole positioning and pressing equipment is mainly used to apply external force to make the two bond tightly after the sole and the upper are glued together, thereby enhancing the penetration and curing effect of the adhesive and improving the peel strength of the shoe. Existing pressing machines generally apply pressure by hydraulic or pneumatically driving the pressure plate. With the help of a special shoe sole pressing mold, the pressure during the shoe sole pressing process can be precisely controlled, which helps to ensure that the adhesive fully penetrates and cures, and improves the bonding strength between the shoe sole and the upper. Through preset mold parameters, the machine can automatically complete the steps of positioning, pressing and releasing the shoe sole, which greatly reduces manual intervention and improves production efficiency. However, in actual use, in order to meet the special needs of users, most existing shoe soles adopt an asymmetrical streamlined design. This results in the center of gravity of the mold that matches the shoe sole being off. If the mold does not provide certain limits or guidance during the movement, it is easy to deviate or wobble, resulting in deviations in the mold movement trajectory and inaccurate pressing. Summary of the Invention

[0003] The purpose of this invention is to address the problem that most existing shoe soles adopt an asymmetrical streamlined design, which leads to a shift in the center of gravity of the mold matching the sole. If the mold is not provided with certain limits or guidance during movement, it is prone to shifting or shaking, resulting in deviations in the mold movement trajectory and inaccurate pressing. Therefore, this invention proposes a pressing equipment and process for the soles of combat boots, training shoes, and adhesive single leather shoes.

[0004] To achieve the above objectives, the present invention employs the following technology: a sole pressing device for combat boots, training shoes, and adhesive single-layer leather shoes, comprising a base and an unpressed sole body, wherein the unpressed sole body is pressed and shaped by a pressing mold; The pressing mold includes a lower positioning frame placed on a base. The lower positioning frame supports the lower mold through a support platform set at the bottom, and the unformed shoe sole body is placed in the lower mold. Above the lower mold is an upper mold for pressing the shoe sole body. The upper mold is movably set in the upper positioning frame with the same dimensions as the inner edge of the lower positioning frame. When the upper mold is subjected to downward pressure, it descends vertically along the inner edge of the upper positioning frame into the lower positioning frame and cooperates with the lower mold to press the shoe sole body into shape. The support platform is provided with at least two positioning pins that penetrate the lower mold, and the upper mold is provided with a rotating pin that cooperates with the positioning pins. When the upper mold and the lower mold are fitted together, the rotating pin and the positioning pin are locked together, so that the upper mold and the lower mold are combined into a mold, and the shoe sole body inside the mold is subjected to continuous pressure. After the sole body and the mold are pressed together, they are taken out from the lower positioning frame through the inner edge of the upper positioning frame. The mold is then separated into an upper mold and a lower mold to remove the sole body.

[0005] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The rotating pin includes several rotating parts that are rotatably embedded in the upper mold. The top and bottom of the rotating parts are respectively equipped with bolt grooves and insertion holes, and the inner wall of the insertion hole is provided with at least one groove equidistantly arranged around it. The positioning pin includes a pin body that is fixedly installed on the support platform and corresponds to the position of the insertion hole. The end of the pin body passes through a through hole opened on the surface of the lower mold and is inserted into the insertion hole. The pin body has at least one receiving groove on its surface, and a protrusion is movably connected in the receiving groove through a second telescopic rod. After the protrusion is embedded in the groove, it locks the connection between the insertion hole and the pin body.

[0006] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The groove sidewall is provided with an inclined surface and a flat surface, the end of the protrusion is provided with an inclined part and a horizontal part that cooperate with the groove, and the top of the protrusion is provided with an inclined surface that cooperates with the inner edge of the insertion hole.

[0007] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The upper mold is provided with at least one fitting part, and the inner wall of the upper positioning frame is provided with a fitting groove for the fitting part to be inserted, and a first telescopic rod supporting the fitting part is provided in the fitting groove. Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The base is provided with a processing platform, which includes a support platform installed on the base. The surface of the support platform is provided with a discharge hole, and a collection cavity is provided below the discharge hole. The mold taken out from the lower positioning frame falls into the collection cavity through the discharge hole. The inclined guide platform at the end of the support platform allows the upper and lower positioning frames of the mold to slide out of the support platform.

[0008] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The upper positioning frame and the lower positioning frame slide through a guide mechanism set on the support platform. The guide mechanism includes a first guide rail set on the support platform. The lower positioning frame is slidably embedded in the first guide rail. A mounting platform is set in the middle of the first guide rail, and first transmission wheels are rotatably set at both ends of the mounting platform. A first internal gear belt is meshed on the two first transmission wheels. Both the upper and lower positioning frames are provided with slides that fit against the mounting platform. Each slide has a limiting groove that fits against the side wall of the mounting platform. Each limiting groove has teeth that engage with the first internal gear belt. When the first internal gear belt rotates, the upper and lower positioning frames slide along the length of the first guide rail.

[0009] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The mounting platform is provided with an inclined lifting part at the end near the guide platform. When the slide slides along the length of the mounting platform to the lifting part, it is lifted, so that the teeth are moved out of the first internal gear belt. The lower positioning frame slides out of the first guide rail and slides into the guide platform together with the upper positioning frame.

[0010] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The upper positioning frame is connected to the lower positioning frame, which is slidably embedded in the first guide rail, through a combination mechanism. The combination mechanism includes a second guide rail on one side of the support platform. Two second rotating wheels are rotatably arranged on the inner wall of the second guide rail, and a second internal gear belt is meshed on the two second rotating wheels. The second internal gear belt meshes with the teeth provided on the upper positioning frame. The inner wall of the second guide rail is provided with a support member that restricts the upper positioning frame. The support member includes a first track and a second track that are horizontally set and vertically arranged. When the upper positioning frame slides horizontally along the length of the first track to the connection point with the second track via the second internal gear belt, the upper positioning frame descends and enters the second track. Additionally, a movable support plate is movably mounted within the second guide rail via a third telescopic rod. When the third telescopic rod is not compressed, the movable support plate is horizontal with the first rail to receive the upper positioning frame. After the upper positioning frame is mounted on the movable support plate, the third telescopic rod is compressed, causing the movable support plate to descend and remain horizontal with the second rail, thus disengaging the teeth from the second internal gear belt.

[0011] Further description of the above-mentioned equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes: The second guide rail surface has a feeding hole for inserting the upper positioning frame. The first rail is located at the feeding hole and has a notch for inserting the upper positioning frame. After the upper positioning frame rises vertically and drives the teeth to engage with the second internal gear belt, the upper positioning frame is pushed into the first rail for limiting by the horizontal movement of the second internal gear belt. The second guide rail surface is also provided with a pusher hole, and a pusher is provided on one side of the second guide rail through the pusher hole. The end of the pusher is connected to a hydraulic push rod provided on the base. The pusher pushes the upper positioning frame in the second rail to move out of the second guide rail and connect with the lower positioning frame.

[0012] A sole pressing process for processing combat boots, training shoes, and adhesive-bonded single-layer leather shoes includes the following steps: S1. The upper positioning frame is raised vertically, causing the teeth to engage with the second internal gear belt. The upper positioning frame is then installed, and the mold is installed inside the upper positioning frame. S2. Install the lower positioning frame in the support platform, and at the same time, the teeth on the limiting groove are engaged and inserted into the first internal gear belt. The lower positioning frame is installed, and the lower mold and the unformed shoe sole body are placed in the lower positioning frame in sequence. S3. Start the output end connected to the first transmission wheel and the second rotating wheel to make the upper positioning frame and the lower positioning frame begin to move; S4. When the upper positioning frame slides along the first track to the point where it connects with the second track, it descends into the second track. S5. Start the hydraulic push rod, insert the pusher into the push hole to push the upper positioning frame out of the second guide rail, and connect it with the lower positioning frame through the slot and the rail. S6. After assembly, the upper positioning frame continues to move with the lower positioning frame to below the main pressing part, the hydraulic press is started, the upper mold cooperates with the lower mold to press the shoe sole body into a closed mold, and the pressure is continuously maintained. S7. The mold closes and moves to the bottom of the second platform. The negative pressure suction cup adheres to the mold closes and tightens. The four bolts are inserted into the bolt slots and rotated. The connection between the positioning pin and the rotating pin is released. The connection between the mold closes and the lower positioning frame is released. S8. The elevator drives the second platform to rise, and the negative pressure suction cup drives the mold to move out of the lower positioning frame. After the lower positioning frame moves away, the sole body and the mold fall into the collection cavity through the material discharge hole. The impact force causes the sole body to separate from the mold, and the sole body processing is completed. S9. Remove the upper and lower positioning frames of the mold while keeping them connected, and slide them out of the support platform via the guide table for collection.

[0013] One of the above technical solutions has the following advantages or beneficial effects: 1. Through the set pressing mold, when the upper mold is subjected to downward pressure, it descends vertically along the inner edge of the upper positioning frame to the lower positioning frame, and cooperates with the lower mold to press and form the shoe sole body. At the same time, the inner edge of the insertion hole can first contact the inclined surface of the top of the protrusion. Under the push of the insertion hole, the protrusion squeezes the second telescopic rod inward to retract, so that the protrusion is completely embedded in the receiving groove. When the insertion hole is completely fitted on the surface of the pin, the elastic deformation of the second telescopic rod recovers and pushes the protrusion out of the receiving groove. The protrusion is inserted into the groove and fixed. The insertion hole and the pin are locked together. The upper mold is fixed on the lower positioning frame by rotating the pin and positioning pin, so that the upper mold and the lower mold can be combined into a mold. The shoe sole body inside the mold is continuously pressed, thereby achieving the purpose of ensuring the bonding strength of the shoe sole body. 2. Through the set processing platform, guiding mechanism, and assembly mechanism, the upper positioning frame is installed, and the upper mold is installed inside the upper positioning frame. The lower positioning frame is installed, and the lower mold and the unformed shoe sole body are placed in sequence inside the lower positioning frame. Then, the hydraulic push rod is activated, and the pusher inserts into the push hole to push the upper positioning frame out of the second guide rail. It is connected to the lower positioning frame through the slot and the rail. After assembly, the upper positioning frame continues to move with the lower positioning frame to below the main pressing part. The hydraulic press is activated, and the main pressing part and the auxiliary pressing part are driven down through the first platform. The upper mold and the fitting part are pressed down. The upper mold cooperates with the lower mold to press the shoe sole body into a closed mold and continuously maintains pressure to achieve the purpose of automated production.

[0016] The following will, with reference to the accompanying drawings of the embodiments of the present invention, clearly and completely describe the equipment and process for pressing the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] To address the problem that most existing shoe soles employ asymmetrical streamlined designs, leading to a shift in the center of gravity of the mold used to match the sole, and the potential for misalignment or wobbling during mold movement without adequate restraint or guidance, resulting in deviations in the mold's trajectory and inaccurate pressing, this invention proposes a pressing device and process for the soles of combat boots, training shoes, and adhesive-bonded single-layer leather shoes. Figure 1 - Figure 20 As shown: Including the base 11 and the unpressed sole body 12, such as Figure 2 - Figure 4 As shown, the unpressed sole body 12 is pressed and formed by a pressing mold 20. The pressing mold 20 includes a lower positioning frame 25 placed on a base 11. The lower positioning frame 25 supports a lower mold 22 via a support platform 26 at its bottom. The unformed sole body 12 is placed in the lower mold 22. An upper mold 21 for pressing the sole body 12 is provided above the lower mold 22. The upper mold 21 is movably disposed within an upper positioning frame 24 with the same inner dimension as the lower positioning frame 25. Preferably, as shown... Figure 18 As shown, the upper positioning frame 24 is provided with a slot 243, and the lower positioning frame 25 is provided with a rail 251 that cooperates with the slot 243. The upper positioning frame 24 is placed on the lower positioning frame 25, and the slot 243 and the rail 251 are aligned. The upper positioning frame 24 is then pushed, and the slot 243 slides and nests on the rail 251, thereby completing the combination of the upper positioning frame 24 and the lower positioning frame 25. When the upper mold 21 is subjected to downward pressure, it descends vertically along the inner edge of the upper positioning frame 24 into the lower positioning frame 25, and cooperates with the lower mold 22 to press and form the sole body 12. Through this design, the upper positioning frame 24 provides a clear pressing path for the upper mold 21, ensuring that the upper mold 21 can move along a predetermined trajectory during the pressing process, avoiding shaking caused by the offset of the center of gravity of the upper mold 21, and avoiding inaccurate pressing. At the same time, the lower positioning frame 25 and the support platform 26 provide a stable support platform for the pressing of the upper mold 21 and the lower mold 22, ensuring that it can remain stable during the pressing process.

[0018] Furthermore, such as Figure 5 - Figure 8 As shown, the support platform 26 is provided with at least two positioning pins 27 that penetrate the lower mold 22. Preferably, there are four positioning pins 27, which are respectively located at the four corners of the support platform 26. The upper mold 21 is provided with rotating pins 23 that cooperate with the positioning pins 27. The rotating pins 23 include four rotating parts 231 that are rotatably embedded in the upper mold 21. The top and bottom of the rotating parts 231 are respectively provided with bolt grooves 232 and insertion holes 233. The inner wall of the insertion hole 233 is provided with at least one groove 234 that is equidistantly arranged. Preferably, there are three insertion holes 233. The positioning pins 27 include pin bodies 271 that are fixedly installed on the support platform 26 and correspond to the position of the insertion holes 233. The end of the pin body 271 penetrates the through hole opened on the surface of the lower mold 22 and is inserted into the insertion hole 233. The surface of the pin body 271 is provided with three receiving grooves 272, and the receiving grooves 272 are movably connected with protrusions 274 through the second telescopic rod 273. The sidewall of the groove 234 is provided with an inclined surface and a flat surface. The end of the protrusion 274 is provided with an inclined part and a horizontal part that cooperate with the groove 234, and the top of the protrusion 274 is provided with an inclined surface that cooperates with the inner edge of the insertion hole 233. Through this design, when the upper mold 21 drives the rotating pin 23 to press down, the inner edge of the insertion hole 233 can first contact the inclined surface of the top of the protrusion 274. Under the push of the insertion hole 233, the protrusion 274 presses the second telescopic rod 273 inward to retract, so that the protrusion 274 is completely embedded in the receiving groove 272. When the insertion hole 233 is fully fitted onto the surface of the pin 271, the second telescopic rod 273 elastically deforms and pushes the protrusion 274 out of the receiving groove 272. The protrusion 274 is inserted into the groove 234 and fixed. The insertion hole 233 is locked to the pin 271. The upper mold 21 is fixed to the lower positioning frame 25 by rotating the pin 23 and the positioning pin 27, so that the upper mold 21 can be combined with the lower mold 22 to form a mold. The shoe sole body 12 inside the mold is continuously pressed, thereby ensuring the bonding strength of the shoe sole body 12. To achieve automatic and rapid continuous pressing, such as Figure 9 - Figure 11As shown, a processing platform 30 is provided on the base 11. The processing platform 30 includes a support platform 31 installed on the base 11. A material discharge hole 32 is opened on the surface of the support platform 31, and a collection cavity 34 is provided below the material discharge hole 32. The mold closing part taken out from the lower positioning frame 25 falls into the collection cavity 34 through the material discharge hole 32. The inclined guide platform 33 at the end of the support platform 31 allows the upper positioning frame 24 and the lower positioning frame 25 to slide out of the support platform 31 through the guide platform 33. The upper positioning frame 24 and the lower positioning frame 25 slide through the guide mechanism 40 provided on the support platform 31. The guide mechanism 40 includes a first guide rail 41 provided on the support platform 31. The lower positioning frame 25 is slidably embedded in the first guide rail 41. A mounting platform 42 is provided in the middle of the first guide rail 41, and first transmission wheels 43 are rotatably provided at both ends of the mounting platform 42. A first internal gear belt 44 is meshed on the two first transmission wheels 43. A slide table 45 that fits against the mounting platform 42 is provided on both the upper positioning frame 24 and the lower positioning frame 25. A limiting groove 46 that fits against the side wall of the mounting platform 42 is provided on the slide table 45. A tooth 47 that engages with the first internal gear belt 44 is provided on any one of the limiting grooves 46. When the first internal gear belt 44 rotates, the upper positioning frame 24 and the lower positioning frame 25 slide along the length direction of the first guide rail 41. With this design, the combined upper positioning frame 24 and lower positioning frame 25 are placed in the support platform 31. The slide table 45 is slidably set on the mounting platform 42 under the restriction of the two limiting grooves 46. At the same time, the teeth 47 on the limiting grooves 46 mesh and insert into the first internal gear belt 44. By starting the power source (not shown in the figure) connected to the first transmission wheel 43, the first transmission wheel 43 starts to rotate and cooperates with another first transmission wheel 43 to start driving the first internal gear belt 44 to move. The first internal gear belt 44 can drive the upper positioning frame 24 and lower positioning frame 25 to move horizontally along the length direction of the mounting platform 42. like Figure 10 As shown, the lifting part 421 is provided with an inclined lifting part 421 at the end near the guide table 33. When the slide table 45 provided on the upper positioning frame 24 slides along the length direction of the mounting platform 42 to the lifting part 421, the upper positioning frame 24 and the lower positioning frame 25 begin to lift under the guidance of the lifting part 421, and drive the teeth 47 to move out of the first internal gear belt 44. At this time, the lower positioning frame 25 slides out of the first guide rail 41 and disengages, and arrives at the guide table 33 together with the upper positioning frame 24.

[0019] Furthermore, such as Figure 1 , Figure 19 and Figure 20As shown, a pressing mechanism 60 for pressing the upper mold 21 and a material taking mechanism 70 for taking out the mold are provided on one side of the support platform 31. The pressing mechanism 60 includes a hydraulic press 61 and a first platform 62 installed on the hydraulic press 61. A main pressing part 63 matching the contour of the upper mold 21 is installed on the first platform 62. Preferred, such as Figure 2 , Figure 4 and Figure 11 As shown, to prevent the upper mold 21 from sliding down to the lower mold 22 due to its own weight before pressing, the upper mold 21 is provided with at least one fitting part 211. The inner wall of the upper positioning frame 24 is provided with a fitting groove 241 for the fitting part 211 to be inserted, and a first telescopic rod 242 supporting the fitting part 211 is provided in the fitting groove 241. An auxiliary pressing part 64 matching the contour of the fitting part 211 is also installed on the first platform 62. When the upper positioning frame 24 and the lower positioning frame 25 slide to below the main pressing part 63, the hydraulic press 61 is started, so that the hydraulic press 61 drives the main pressing part 63 and the auxiliary pressing part 64 to descend through the first platform 62 and press down the upper mold 21 and the fitting part 211. The upper mold 21 cooperates with the lower mold 22 to press the shoe sole body 12 and combine to form a mold. At the same time, the fitting part 211 compresses the first telescopic rod 242 under the guidance of the fitting groove 241. The material handling mechanism 70 includes a lifting platform 71 and a second platform 72 mounted on the lifting platform 71. The second platform 72 is equipped with a negative pressure suction cup 73 for suction and mold closing. Bolts 74, which rotatably engage with bolt slots 232, are also mounted on the second platform 72. When the mold closing mechanism moves below the second platform 72, the lifting platform 71 lowers the second platform 72, causing the negative pressure suction cup 73 to adhere to and tighten the mold closing mechanism. Simultaneously, the four bolts 74 are inserted into the bolt slots 232 and rotated. This causes the bolt slots 232 to rotate via the rotating part 231, rotating the insertion hole 233. The insertion hole 233 causes the inclined surface of the inner wall of the groove 234 to engage with the inclined portion at the end of the protrusion 274, pushing the protrusion 274 into the receiving groove 272. Simultaneously, the second telescopic rod 273 is compressed and retracted, causing the protrusion 274 to move out of the groove 234. The mold is removed and stored in the receiving groove 272 under the restriction of the inner wall of the insertion hole 233. The connection between the positioning pin 27 and the rotating pin 23 is released. At this time, the elevator 71 drives the second platform 72 to rise. The second platform 72 drives the mold to move out from the lower positioning frame 25 and the upper positioning frame 24 through the negative pressure suction cup 73. Wait for the lower upper positioning frame 24 and the lower positioning frame 25 to move away. The negative pressure suction cup 73 releases the negative pressure adsorption, so that the sole body 12 and the mold fall into the collection cavity 34 through the material discharge hole 32. The impact force generated by the fall separates the sole body 12 that is bonded together from the mold. The sole body 12 is processed. The upper positioning frame 24 and the lower positioning frame 25 that are removed from the mold slide out of the bearing platform 31 through the guide table 33 while maintaining the connection.

[0020] Furthermore, in order to quickly assemble the upper positioning frame 24 and the lower positioning frame 25, such as... Figure 12 - Figure 18 As shown, the upper positioning frame 24 is connected to the lower positioning frame 25, which is slidably embedded in the first guide rail 41, through the combination mechanism 50. The combination mechanism 50 includes a second guide rail 51 disposed on one side of the support platform 31. Two second rotating wheels 52 are rotatably disposed on the inner wall of the second guide rail 51, and a second internal gear belt 53 is meshed on the two second rotating wheels 52. The second internal gear belt 53 meshes with the teeth 47 disposed on the upper positioning frame 24. By starting the power source (not shown in the figure) connected to the second rotating wheels 52, the upper positioning frame 24 can be driven to move through the second internal gear belt 53. The inner wall of the second guide rail 51 is provided with a support member 54 that restricts the upper positioning frame 24. The support member 54 includes a first track 541 and a second track 542 that are horizontally arranged and vertically aligned. When the upper positioning frame 24 slides horizontally along the length direction of the first track 541 to the point where it connects with the second track 542 via the second internal gear belt 53, the upper positioning frame 24 descends and enters the second track 542. The movable support plate 544 is movably set in the second guide rail 51 by the third telescopic rod 543. When the third telescopic rod 543 is not compressed, the movable support plate 544 is horizontal with the first rail 541 to receive the upper positioning frame 24. After the upper positioning frame 24 is mounted on the movable support plate 544, the third telescopic rod 543 is compressed, the movable support plate 544 descends and remains horizontal with the second rail 542, so that the teeth 47 disengage from the second internal gear belt 53. It should be noted that at this time, the upper positioning frame 24 and the lower positioning frame 25 are in contact and the position of the slot 243 corresponds to the position of the rail 251. The surface of the second guide rail 51 is provided with a feeding hole 511 for inserting the upper positioning frame 24. The first rail 541 is provided with a notch for inserting the upper positioning frame 24 at the feeding hole 511. When the upper positioning frame 24 needs to be installed, the upper positioning frame 24 is raised vertically to drive the teeth 47 to be inserted into the second internal gear belt 53. Then, the upper positioning frame 24 is pushed into the first rail 541 for limiting by the horizontal movement of the second internal gear belt 53. The installation of the upper positioning frame 24 is completed. The surface of the second guide rail 51 is also provided with a push hole 512. A pusher 56 is provided on one side of the second guide rail 51, which passes through the push hole 512. The end of the pusher 56 is connected to the hydraulic push rod 55 provided on the base 11. By activating the hydraulic push rod 55, the output end of the hydraulic push rod 55 pushes the pusher 56 into the push hole 512 and fits against the upper positioning frame 24 that has descended into the second track 542. The pusher 56 pushes the upper positioning frame 24 out of the second guide rail 51 and completes the connection with the lower positioning frame 25 through the slot 243 and the rail 251. The upper positioning frame 24 and the lower positioning frame 25 are then combined.

[0021] This application also provides a sole positioning and pressing process, including the following steps: S1. The upper positioning frame 24 is vertically raised, causing the teeth 47 to engage with the second internal gear belt 53. The upper positioning frame 24 is pushed into the first track 541 limit by the horizontal movement of the second internal gear belt 53. The upper positioning frame 24 is installed and the upper mold 21 is installed inside the upper positioning frame 24. S2. The lower positioning frame 25 is installed in the support platform 31. The slide table 45 is slidably set on the support platform 42 under the restriction of the two limiting grooves 46. At the same time, the teeth 47 on the limiting grooves 46 are engaged and inserted into the first internal gear belt 44. The lower positioning frame 25 is installed. The lower mold 22 and the unformed shoe sole body 12 are placed in the lower positioning frame 25 in sequence. S3. Start the output end connected to the first transmission wheel 43 and the second rotating wheel 52 to make the upper positioning frame 24 and the lower positioning frame 25 start to move; S4. When the upper positioning frame 24 slides along the first track 541 to the connection point with the second track 542, it descends into the second track 542. The movable bearing plate 544 descends to make the teeth 47 disengage from the second internal gear belt 53. At this time, the upper positioning frame 24 and the lower positioning frame 25 fit together and the slot 243 corresponds to the position of the track 251. S5. Start the hydraulic push rod 55, push the pusher 56 into the push hole 512 to push the upper positioning frame 24 out of the second guide rail 51, and connect it to the lower positioning frame 25 through the slot 243 and the rail 251. S6. After assembly, the upper positioning frame 24 continues to move with the lower positioning frame 25 to below the main pressing part 63. The hydraulic press 61 is started, and the main pressing part 63 and the auxiliary pressing part 64 are driven down through the first platform 62 to press down the upper mold 21 and the fitting part 211. The upper mold 21 cooperates with the lower mold 22 to press the shoe sole body 12 into a mold and continuously maintain pressure. The fitting part 211 compresses the first telescopic rod 242. S7. The mold moves to below the second platform 72. The elevator 71 drives the second platform 72 to descend. The negative pressure suction cup 73 adheres to the mold and clamps it. The four bolts 74 are inserted into the bolt groove 232 and rotated. The bolt groove 232 drives the insertion hole 233 to rotate through the rotating part 231, so that the inclined surface of the inner wall of the groove 234 adheres to the inclined part at the end of the protrusion 274, pushing the protrusion 274 to move into the receiving groove 272, squeezing the second telescopic rod 273 to retract. The protrusion 274 moves out of the groove 234 and is stored in the receiving groove 272. The connection between the positioning pin 27 and the rotating pin 23 is released, and the connection between the mold and the lower positioning frame 25 is released. S8. The elevator 71 drives the second platform 72 to rise, and the negative pressure suction cup 73 drives the mold to move out of the lower positioning frame 25. After the lower positioning frame 25 moves away, the shoe sole body 12 and the mold fall into the collection cavity 34 through the material discharge hole 32. The impact force causes the shoe sole body 12 to separate from the mold, and the shoe sole body 12 is processed. S9. Remove the upper positioning frame 24 and lower positioning frame 25 of the mold and slide them out of the support platform 31 through the guide table 33 while maintaining the connection.
