A heat-insulating cotton insole and its production finishing process

Abstract

The present invention relates to the field of pressure equipment, specifically a heat-insulating cotton insole and its production finishing process. A hot press main body is used to finish the sheet material to form the shape of an insole. The multi-layer structure of the sheet material layer includes fabric, heat-insulating cotton, foam, and aluminum foil. A fabric mechanism, a feeding mechanism, and a discharging mechanism are arranged around the lower mold of the hot press main body. By setting one side of the sheet material as aluminum foil, the present invention not only uses the aluminum foil to cooperate with the heat-insulating cotton to make the insole have a better heat-insulating effect, but also reduces the contact friction force with each mechanism compared with the sheet material on the surface of rubber and foam. At the same time, a feeding mechanism and a fabric mechanism are arranged around the mold of the hot press. The feeding mechanism overcomes the friction hindrance between the sheet materials through the discharging component and conveys the stacked sheet materials out individually. The fabric mechanism extracts the single sheet materials through the clamping mechanism and arranges them on the lower mold, so that the sheet materials can be automatically fed for processing and production, making the production more convenient.

Description

Technical Field

[0001] The present invention relates to the field of pressure equipment, and specifically to a thermal insulation cotton insole and its production finishing process. Background Art

[0002] During the insole production process, square sheets are usually used for hot pressing and cutting. The square sheets are laminated and bonded by multiple layers of rubber or polymer materials. Subsequently, a hot pressing and shaping device is used to heat and press them to form a concave and convex shape that fits the foot structure. Finally, it is sent to the cutting process to cut out the shape of the required insole, thereby obtaining the insole.

[0003] Since the surface of the rubber sheet has a large frictional force and is soft in texture, it is easy for the sheets to be difficult to automatically separate due to adsorption or adhesion after stacking. When using traditional automated equipment, problems such as material jamming and multi-sheet bonding are likely to occur. Therefore, in the prior art, manual loading and unloading operations are usually adopted. On the contrary, relying on manual labor also limits the production process and causes many inconveniences to production. Summary of the Invention

[0004] In view of the above problems, the present invention provides a production finishing process for thermal insulation cotton insoles. The hot press main body is used to finish the sheets to form the shape of the insole. The hot press main body includes a pressure head and a workbench. An upper mold is provided on the pressure head and a lower mold is provided on the workbench. A cloth feeding mechanism is provided around the lower mold, and a loading mechanism and an unloading mechanism are respectively provided on both sides of the workbench. The process is carried out in the following steps:

[0005] S1. Prepare the sheets and stack a number of sheets on the loading mechanism;

[0006] S2. Load and feed the cloth. The loading mechanism prepares to output a single sheet from the stacked sheets, and the cloth feeding mechanism drives the single sheet output by the loading mechanism to move to the lower mold of the hot press main body;

[0007] S3. Hot press and finish. The pressure head of the hot press main body descends to drive the upper mold to press on the sheet on the lower mold, and the sheet forms a shape that conforms to the insole main body under the hot press of the upper mold and the lower mold;

[0008] S4. Unload and cool. After the hot press finishing step is completed, the pressure head drives the upper mold to rise, and the unloading mechanism takes the sheet on the lower mold away from the lower mold for subsequent cutting;

[0009] The sheets in S1 are composed of several laminated materials. The laminated materials include cloth, thermal insulation cotton, foam, and aluminum foil. The two sides of the sheet are cloth and aluminum foil respectively;

[0010] The loading mechanism in S2 includes a material rack for placing sheets and a discharging component for driving a single sheet to be separately output from the stacked sheets. The cloth feeding mechanism in S2 is movably installed on the workbench through a moving component. The cloth feeding mechanism includes a clamping mechanism that moves on the moving component and is used to drive the sheet of the loading mechanism to move onto the lower mold.

[0011] Further, the single sheet driven by the loading mechanism in S2 is separately output from the bottom of the stacked sheets. A base is provided below the material rack of the loading mechanism in S2, and the discharging component of the loading mechanism is installed on the base. The discharging component includes a middle frame located in the middle of the base and side frames on the sides of the base. The middle frame and the side frames form at least three supporting parts at the front side, middle, and rear side of the sheet. The side frames are swingably installed on the base, and a second push-pull actuator is connected between the side frames and the base to drive the side frames to swing. The swing axis of the side frames is perpendicular to the movement direction of the cloth feeding mechanism. The side frames swing outward to the sheet, causing the edge of the sheet to lose the support of the side frames and droop. The side frames that swing outward to the sheet swing inward, and then the top ends of the side frames are inserted between the penultimate layer of sheets and the antepenultimate layer of sheets. The loading mechanism further includes a guiding and lifting component for guiding the side frames to rise so as to lift the penultimate layer and the upper sheets.

[0012] Further, contact wheels are provided at the top ends of both the middle frame and the side frames for contacting the sheets. The middle frame and the side frames drive the contact wheels at the top ends to support the sheets in the material rack. The length of the side frames is greater than the length of the sheets, and the contact wheels on the side frames enter between the penultimate layer of sheets and the antepenultimate layer of sheets.

[0013] Further, the middle frame is slidably installed on the base, and a first push-pull actuator is connected between the middle frame and the base to drive the middle frame to slide. The sliding direction of the middle frame is parallel to the movement direction of the cloth feeding mechanism. Two middle frames are separately provided at the bottom end of the sheet and form two supporting parts in the middle of the sheet. The first push-pull actuator drives the two middle frames to approach or move away from each other. The middle frames approach each other, increasing the distance that the sheets extend from the middle frames and thus increasing the drooping amplitude of the sheets.

[0014] Further, the guiding and lifting component includes a substrate. An inclined lifting groove is provided on the substrate. Side rotating shafts are provided on both sides of the side frames and are nested in the inclined lifting groove. A first return spring is provided between the side rotating shafts and the top end of the inclined lifting groove. The loading mechanism further includes a guiding and lifting frame installed on the base. The front end surface of the guiding and lifting frame is inclined and is used to contact the side frames. The distance between the top end of the front end surface of the guiding and lifting frame and the middle frame is less than the distance between the bottom end and the middle frame. The inclination amplitude of the inclined lifting groove is the same as the inclination amplitude of the front end surface of the guiding and lifting frame. The included angle between the side frames against the guiding and lifting frame and the second push-pull actuator is greater than 90°.

[0015] Furthermore, the moving assembly includes a guide rail installed on the workbench and a slider slidably installed on the guide rail. The cross frame of the material distribution mechanism in S2 is installed on the slider so as to move on the workbench. The clamping mechanism includes a clamping cylinder. A limit block is provided on the side of the lower mold in S2 away from the feeding mechanism to limit the position of the sheet brought by the clamping mechanism. A makeshift groove is provided on the side of the limit block to make way for the clamping mechanism. A guide seat is provided on the workbench to drive the horizontal height of the cross frame to descend so that the clamping mechanism drives the sheet to descend to the top surface of the lower mold for placement.

[0016] Furthermore, the cross frame is connected to the slider through a sliding seat, the sliding seat is provided with a vertical guide rail, the cross frame and the guide rail are nested and connected, and a second return spring is provided between the cross frame and the sliding seat; a driven wheel is provided on the side of the cross frame, and an inclined guide groove is provided on the guide seat, and the opening of the guide groove at one end close to the feeding mechanism is located on the moving path of the driven wheel, and the horizontal height of the guide groove at one end close to the feeding mechanism is higher than the horizontal height of the guide groove at one end away from the feeding mechanism.

[0017] Furthermore, an auxiliary support mechanism is provided on the cross frame of the cloth mechanism in S2, which is used to support the bottom of the sheet when the clamping mechanism drives the sheet to move, and the auxiliary support mechanism includes a movable seat and a cross support rod movably installed in the movable seat, and a rotary actuator is provided on the cross frame to drive the cross support rod to perform telescopic movements; the auxiliary support mechanism also includes a chain storage mounting seat and a chain installed in the chain storage mounting seat, the chain is connected to the cross support rod, and a driving sprocket is also provided in the chain storage mounting seat, and the rotary actuator is connected to the driving sprocket to drive the chain to move.

[0018] Furthermore, the chain includes a plurality of chain links hinged to each other, a mutual limiting section is provided on one side of the chain link, the mutual limiting section is sheet-shaped and the plane of the sheet-shaped structure is parallel to the hinge swing axis of the chain link, and the length of the mutual limiting section is equal to the spacing between the hinge connection points at both ends of a single chain link; the driving sprocket drives the chain to extend and the chain links are offset by the mutual limiting sections to make the chain straight.

[0019] A thermal insulation cotton insole is obtained by a thermal insulation cotton insole production and finishing process to obtain a sheet material in the shape of an insole, and the sheet material in the shape of an insole is cut along the contour of the insole to obtain an insole main body, wherein the thickness of the foam in the insole main body accounts for 40%-60% of the total thickness; the fabric is terry cloth, and the foam is Combo foam.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, one side of the sheet for producing the insole is made of aluminum foil. Not only does the aluminum foil cooperate with the heat-insulating cotton to make the produced insole have a better heat-insulating effect, but also the friction between the sheet and various mechanisms is reduced compared with the sheets having rubber surfaces or foam surfaces. At the same time, a feeding mechanism and a cloth-feeding mechanism are arranged around the mold of the hot press. The feeding mechanism overcomes the frictional resistance between the sheets through the discharging assembly and conveys the stacked sheets out individually. The cloth-feeding mechanism extracts the single sheets through the clamping mechanism and arranges them on the lower mold, so that the sheets can be automatically fed for processing and production, making the production more convenient.

[0022] Moreover, in the present invention, a middle support and a side support are arranged under the material rack to cooperate in supporting the stacked sheets. The side support is arranged to be able to swing outwards and inwards and move upwards. Thus, after the side support swings outwards and the sheets lose support and sag, the side support can immediately swing inwards and enter between two sheets, and then the upper sheet is lifted by moving upwards, so that the bottom sheet is separated and taken away by the cloth-feeding mechanism. In addition, two middle supports are arranged to be able to move closer or farther away from each other, so that the support range for the sheets can be tested and set, and the sheets can sag to a proper position.

[0023] Moreover, the present invention also arranges an auxiliary support mechanism to cooperate with the clamping mechanism clamping the sheet. The moving sheet is supported by a cross brace, reducing the friction caused by the sagging of the sheet with other mechanisms and resulting in deviation of the cloth. The chain is used for linear transmission so that the cross brace can quickly extend and retract, facilitating timely support for the sheet. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0038] Embodiment, as Figures 1-9 shown: The present invention provides a heat-insulating cotton insole and its production and finishing process. Among them, the heat-insulating cotton insole is obtained by finishing the sheet material A into a sheet material A with the shape of an insole, and the insole body B is obtained after cutting and processing the sheet material A with the shape of an insole;

[0039] The used sheet material A is composed of several laminated materials. The laminated materials include fabric, heat-insulating cotton, foam, and aluminum foil. The two sides of the sheet material A are fabric and aluminum foil respectively, and there is no change in the material of the sheet material A with the shape of an insole after finishing;

[0040] The heat-insulating cotton insole of this embodiment is obtained by cutting a sheet A with the shape of an insole along the insole contour, and includes an insole body B. The thickness of the foam in the insole body B accounts for 40%-60% of the total thickness; the fabric is terry cloth, and the foam is Kangbao foam. The heat-insulating cotton can be made of rubber and plastic heat-insulating cotton, polyurethane foam, plush cotton, etc. according to the needs of those skilled in the art. It is known that the cutting equipment can be a pressure cutting machine with a cutting die, or trimmed manually, which will not be elaborated here.

[0041] The production finishing process of the heat-insulating cotton insole of this embodiment uses a hot press main body 1 to finish the sheet A so that the sheet A forms the shape of an insole. The hot press main body 1 includes a pressing head 12 and a workbench 11. An upper die is provided on the pressing head 12 and a lower die 13 is provided on the workbench 11. At a certain temperature, the pressing head 12 drives the upper die to extrude the sheet A on the lower die 13, so that the insole is heat-set into the shape of an insole. A fabric mechanism 3 is provided around the lower die 13, and a feeding mechanism 2 and a discharging mechanism 4 are respectively provided on both sides of the workbench 11. Thus, it includes three parts: a feeding mechanism 2, a fabric mechanism 3, and a discharging mechanism 4.

[0042] For the feeding mechanism 2, the feeding mechanism 2 includes a material rack 21 for placing the sheet A and a discharging component for driving a single sheet of the sheet A to be separately output from the stacked sheets A. In this embodiment, the single sheet of the sheet A driven by the feeding mechanism 2 is separately output from the bottom of the stacked sheets A, which can ensure that the output of the lower sheet A will not be interrupted when the sheet A is placed above the material rack 21, and the sheet A can move downward to the discharging component below by its own weight;

[0043] Therefore, a base 22 is provided below the material rack 21, and the discharging component of the feeding mechanism 2 is installed on the base 22. The discharging component includes a middle frame 24 in the middle of the base 22 and a side frame 26 on the side of the base 22. The middle frame 24 and the side frame 26 form at least three supporting parts for the sheet A at the front side, middle part, and rear side. When no material is discharged, the middle frame 24 and the side frame 26 support the upper sheet A. Contact wheels 23 are provided at the tops of the middle frame 24 and the side frame 26 for contacting the sheet A, and the middle frame 24 and the side frame 26 drive the contact wheels 23 at the top to support the sheet A in the material rack 21;

[0044] Among them, the side frame 26 is swingably installed on the base 22, and a cylinder-type second push-pull actuator 27 is connected between the side frame 26 and the base 22 to drive the side frame 26 to swing. The swing axis of the side frame 26 is perpendicular to the movement direction of the fabric mechanism 3, so that the swing of the side frame 26 is outwardly unfolded and inwardly clamped. It should be noted that the length of the side frame 26 is greater than the length of the sheet A;

[0045] Moreover, the middle frame 24 is slidably mounted on the base 22. A cylinder-type first push-pull actuator 25 is connected between the middle frame 24 and the base 22 to drive the middle frame 24 to slide. The sliding direction of the middle frame 24 is parallel to the moving direction of the fabric mechanism 3. In this embodiment, two middle frames 24 are respectively provided at the bottom end of the sheet A and two supporting parts are formed in the middle of the sheet A. The first push-pull actuator 25 drives the two middle frames 24 to approach or move away from each other, so as to adjust the supporting position and supporting range of the sheet A;

[0046] And, the discharging assembly further includes a guiding and lifting assembly 28 for guiding the side frame 26 to rise so as to lift the second-to-last layer and the upper sheets A. The guiding and lifting assembly 28 includes a substrate 281. An inclined lifting groove 281a is provided on the substrate 281. Side rotating shafts 26a are provided on both sides of the side frame 26 and are nested in the inclined lifting groove 281a. A first return spring 283 is provided between the side rotating shafts 26a and the top end of the inclined lifting groove 281a to drive the side rotating shafts 26a on both sides of the side frame 26 to stably stay at the bottom of the inclined lifting groove 281a. Optionally, for those skilled in the art, a bearing 282 is nested on the side rotating shaft 26a to make the movement of the rotating shaft in the inclined lifting groove 281a smoother. A top seat 284 is further provided between the bearing 282 and the first return spring 283 to prevent the first return spring 283 from being offset by force;

[0047] Not only that, the discharging assembly further includes a guiding and lifting frame 29. The guiding and lifting frame 29 is mounted on the base 22. The front end face of the guiding and lifting frame 29 is inclined and is used to contact the side frame 26. The distance between the top end of the front end face of the guiding and lifting frame 29 and the middle frame 24 is smaller than the distance between the bottom end and the middle frame 24, so as to determine the inclination direction of the front end face of the guiding and lifting frame 29. It should be noted that the inclination amplitude of the inclined lifting groove 281a is the same as that of the front end face of the guiding and lifting frame 29. Moreover, the included angle between the side frame 26 abutted against the guiding and lifting frame 29 and the second push-pull actuator 27 is greater than 90°, which makes the force applied by the second push-pull actuator 27 and the resultant force of the side frame 26 on the guiding and lifting frame 29 not be counteracted in the reverse direction;

[0048] Therefore, the discharging assembly discharges the sheet A separately through three steps:

[0049] First, the second push-pull actuator 27 drives the side frame 26 to swing towards the outside of the sheet A, so that the edge of the sheet A loses the support of the side frame 26 and droops. At the same time, the first push-pull actuator 25 drives the two middle frames 24 to approach each other, controlling the distance that the sheet A extends from the middle frames 24. The increased extension distance further increases the drooping amplitude of the sheet A;

[0050] Then, the second push-pull actuator 27 drives the side frame 26 to swing towards the inner side of the sheet A, so that the top end of the side frame 26 is inserted between the lowermost layer of the sheet A and the second-lowermost layer of the sheet A. The contact wheel 23 on the side frame 26 enters between the lowermost layer of the sheet A and the second-lowermost layer of the sheet A, and the sheet A passes through the side frame 26;

[0051] Finally, the second push-pull actuator 27 continues to drive, and the side frame 26 abuts against the guiding and lifting frame 29 and slides upward on the guiding and lifting frame 29, so as to lift the second-lowermost layer and the upper sheets A, separating the lowermost layer of the sheet A and the second-lowermost layer of the sheet A that are in contact with each other, thus avoiding mutual contact and friction between the sheets A. At this time, the cloth feeding assembly can come to take away the lowermost layer of the sheet A, that is, the sheet A located between the side frame 26 and the middle frame 24.

[0052] It should be noted that for those skilled in the art, the amplitude of the sag of the sheet A can be obtained through actual tests to get a stable sag amplitude and position range, or can be detected by a sensor, so as to determine the working range, stopping position and time node of the first push-pull actuator 25.

[0053] For the cloth feeding mechanism 3, the cloth feeding mechanism 3 is movably installed on the workbench 11 through the moving assembly 5. The cloth feeding mechanism 3 includes a clamping mechanism that moves on the moving assembly 5 for driving the sheet A of the feeding mechanism 2 to move onto the lower mold 13. Specifically, the moving assembly 5 includes a guide rail 51 installed on the workbench 11 and a slider 53 slidably installed on the guide rail 51, as well as a transmission belt 52 for driving the slider 53 to move and a motor for driving the transmission belt 52 to operate. The cross frame 32 of the cloth feeding mechanism 3 is installed on the slider 53 and thus moves on the workbench 11. The clamping mechanism includes a jaw cylinder 33, that is, a finger cylinder, with a pair of jaws at the front end of the cylinder. The jaws are driven by the cylinder to open or clamp. Correspondingly, a limiting block 13b is provided on one side of the lower mold 13 away from the feeding mechanism 2 to limit the position of the sheet A brought by the clamping mechanism. A relief groove 13a is provided on the side of the limiting block 13b to make way for the clamping mechanism, so that the clamping mechanism can drive the sheet A to move to the top surface of the lower mold 13. And a guiding and descending seat 6 is provided on the workbench 11 to drive the horizontal height of the cross frame 32 to descend, so that the clamping mechanism drives the sheet A to descend to the top surface of the lower mold 13 for placement;

[0054] To this end, the cross frame 32 is connected to the slider 53 through the sliding seat 31, and a vertical guide rail 321 is provided on the sliding seat 31. The cross frame 32 and the guide rail 321 are nested and connected, and a second return spring 322 is provided between the cross frame 32 and the sliding seat 31; a driven wheel 31a is provided on the side of the cross frame 32, and an inclined guide groove 6a is provided on the guide seat 6, and the opening of the guide groove 6a at one end close to the feeding mechanism 2 is located on the moving path of the driven wheel 31a, and the guide groove 6a is close to the feeding mechanism 2. The horizontal height of one end is higher than the horizontal height of the end of the guide groove 6a away from the feeding mechanism 2. Therefore, when the clamping mechanism on the horizontal frame 32 drives the sheet A to move to the lower mold 13, the driven wheel 31a enters the guide groove 6a. As the horizontal frame 32 continues to move, the driven wheel 31a is affected by the guide groove 6a and descends along the guide groove 6a, causing the horizontal height of the horizontal frame 32 to drop. Then the clamping cylinder 33 is deployed at the make way groove 13a, so that the sheet A is placed on the lower mold 13.

[0055] It should be noted that the sheet A clamped by the clamping claw cylinder 33 will sag, so that the aluminum film of the sheet A can be located at the bottom for stacking, so that when the bottom surface of the sheet A sags and contacts the lower mold 13, there will not be too much friction;

[0056] However, in this embodiment, in addition to this, an auxiliary support mechanism 34 is also provided on the horizontal frame 32 of the cloth mechanism 3, which is used to support the bottom of the sheet A when the clamping mechanism drives the sheet A to move. The auxiliary support mechanism 34 includes a movable seat 343 and a horizontal support rod 341 movably installed in the movable seat 343. A rotary actuator 342 is provided on the horizontal frame 32 to drive the horizontal support rod 341 to perform telescopic movement;

[0057] Specifically, the auxiliary support mechanism 34 also includes a chain mounting seat 344 and a chain 345 installed in the chain mounting seat 344, the chain 345 is connected to the cross brace rod 341, and a driving sprocket 346 is also provided in the chain mounting seat 344. The rotary actuator 342 is connected to the driving sprocket 346 to drive the chain 345 to move, and the chain 345 includes a plurality of chain links 3451 hingedly connected to each other, and a mutual limiting section 3452 is provided on one side of the chain link 3451, and the mutual limiting section 3452 is in the form of a sheet and the flat sheet structure The surface is parallel to the hinge swing axis of the chain link 3451, and the length of the mutual limiting section 3452 is equal to the spacing between the hinge connection points at both ends of a single chain link 3451, so that the chain links 3451 of the chain 345 extended by the driven sprocket 346 are offset against each other through the mutual limiting section 3452, so that the chain 345 is extended in a straight shape, thereby driving the cross support rod 341 to extend to support the bottom of the sheet A, and the use of the chain 345 can drive the cross support rod 341 to extend and retract with a large stroke in a short time, making the movement faster.

[0058] For the blanking mechanism 4, the blanking mechanism 4 is installed through the moving component 5, including the jaw cylinder 33 and the mounting bracket connecting the jaw cylinder 33 and the slider 53. The slider 53 drives the jaw cylinder 33 to extend into the hot press main body 1 to clamp the sheet A on the lower die 13 and drive it, so that the fabric mechanism 3 can continue fabricating. It can be known that a relief groove 13a is also provided on the lower die 13 for the jaw cylinder 33 of the blanking mechanism 4.

[0059] The production finishing process of the thermal insulation cotton insole in this embodiment is carried out in the following steps:

[0060] S1. Prepare the sheet A and stack a number of sheet A on the feeding mechanism 2;

[0061] S1-1. The second push-pull actuator 27 drives the side frame 26 to swing outward from the sheet A, causing the edge of the sheet A to sag due to the loss of support from the side frame 26. At the same time, the first push-pull actuator 25 drives the two middle frames 24 to move closer to each other, controlling the distance that the sheet A extends from the middle frame 24. As the extended distance increases, the sag amplitude of the sheet A increases;

[0062] S1-2. The second push-pull actuator 27 drives the side frame 26 to swing inward from the sheet A, so that the top of the side frame 26 is inserted between the penultimate layer of sheet A and the antepenultimate layer of sheet A. The contact wheel 23 on the side frame 26 enters between the penultimate layer of sheet A and the antepenultimate layer of sheet A, and the sheet A passes through the side frame 26;

[0063] S1-3. The second push-pull actuator 27 continues to drive, and the side frame 26 abuts against the lifting guide frame 29 and slides upward on the lifting guide frame 29, so as to lift the penultimate layer and the upper sheets A, separating the penultimate layer of sheet A and the antepenultimate layer of sheet A that are in contact with each other;

[0064] S2. Feeding and fabricating. The feeding mechanism 2 prepares to output a single sheet A from the stacked sheet A, and the fabric mechanism 3 drives the single sheet A output by the feeding mechanism 2 to move to the lower die 13 of the hot press main body 1;

[0065] S2-1. During the process of the clamping mechanism clamping and extracting the sheet A, the auxiliary support mechanism 34 works to drive the cross support rod 341 to extend, and the supporting length of the cross support rod 341 for the sheet A is not less than half of the width of the sheet A;

[0066] S2-2. The auxiliary support mechanism 34 gradually drives the cross support rod 341 to retract during the process of the clamping mechanism descending until the sheet A is placed on the lower die 13;

[0067] S3. Hot pressing and finishing. The pressure head 12 of the hot press main body 1 descends to drive the upper die to press on the sheet A on the lower die 13, and the sheet A forms the shape conforming to the insole main body B under the hot pressing of the upper die and the lower die 13;

[0068] S4. Blanking and cooling: After the hot pressing and finishing step is completed, the pressure head 12 drives the upper die to rise, and the blanking mechanism 4 takes the sheet A on the lower die 13 away from the lower die 13 for subsequent cutting.
