Description

Technical Field

[0001] This invention relates to the field of hot pressing equipment for shoe materials, specifically a fully automatic multi-station hot pressing molding equipment for shoe materials. Background Technology

[0002] Hot pressing of shoe materials is a core process in the production of sports shoes and casual shoes. Components such as shoe uppers, toes, linings, and midsoles all need to be shaped, bonded, and reinforced through hot pressing. Traditional single-station hot pressing equipment is only equipped with a single hot pressing station and can only complete one set of shoe materials processing at a time, resulting in slow production cycle and low equipment space utilization.

[0003] Existing equipment uses a double-roller extrusion molding structure, which is only suitable for thin material extrusion molding and cannot be adapted to the hot pressing processing of shoe materials with certain thickness and irregular contours. Most existing conventional shoe material hot presses use fixed single-set hot pressing mold bases with fixed mold base spacing and pressing stroke. They cannot quickly adjust the pressing gap according to different shoe sizes and thicknesses of shoe materials. When changing shoe material types, the entire mold frame needs to be disassembled, which is time-consuming. At the same time, traditional equipment relies on manual timed feeding of raw materials. The shoe material hot melting raw material storage chamber does not have a liquid level linkage conveying structure. When the raw materials are exhausted, the equipment runs idle, which can easily cause defective shoe materials. Conventional hot pressing equipment does not have a unified material collection and storage structure after discharge. The processed shoe materials are scattered and piled up, requiring secondary manual sorting and transportation, which increases labor costs.

[0004] Existing multi-station hot pressing equipment generally suffers from the following defects: The multiple sets of hot press roller mold frames are integrally welded and fixed structures. The mold frames have no sliding adjustment groove structure, and the pressing gap between each set of hot press rollers cannot be adjusted independently, making it impossible to adapt to the simultaneous processing of shoe materials of different thicknesses such as toe, lining, and midsole. The raw material storage box and the hot pressing extrusion chamber rely solely on the manual opening and closing of the conveying pipeline. There is no mechanical automatic feeding component linked to the water pump and level gauge, and the raw material replenishment depends on manual operation. The hot press plate has only a single vertical pressing structure and no independent extrusion chamber with ring-shaped multi-column support. The hot pressing force is uneven, the corners of irregular shoe materials are not properly formed, and the yield rate is low. After multi-station processing, the finished products are not stored in a unified bottom collection box. The molded shoe materials fall directly to the ground, which easily causes scratches and deformation, increasing the defect rate.

[0005] Therefore, there is an urgent need to design a fully automatic multi-station hot pressing molding equipment for shoe materials, and to solve technical defects such as adjustable gaps between multiple stations, automatic mechanical feeding, uniform hot pressing support, and centralized storage of finished products through mechanical structure improvements. Summary of the Invention

[0006] To address the technical problems of traditional shoe material hot pressing equipment in existing technologies, such as single workstation, non-adjustable hot pressing mold gap, manual material replenishment, uneven hot pressing force, and lack of dedicated storage structure for finished products, this invention provides a fully automatic multi-station shoe material hot pressing molding processing equipment. Through pure mechanical structure optimization, it achieves four major mechanical innovations: independently adjustable gaps between multiple workstations, automatic mechanical material conveying, balanced support for hot pressing by annular columns, and unified collection and storage of finished products. It can improve the efficiency of shoe material hot pressing processing and the yield of molded products without relying on electronic control intelligent programs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic multi-station shoe material hot pressing forming processing equipment, comprising a frame housing, wherein a set of longitudinal sliding grooves are formed on each of the left and right sides of the outer wall of the frame housing, and two sets of first mounting brackets are symmetrically arranged on the outer wall of the frame housing and beside the sliding grooves, and the two sets of first mounting brackets are respectively locked to the frame housing by two sets of first fastening bolts; a set of drive motors is fixedly mounted on the top of each set of first mounting brackets, and a drive spindle is respectively assembled at the output end of each set of drive motors, and a connecting flange is fixedly mounted on the end of the drive spindle away from the drive motor, and a hot pressing forming roller is fixedly assembled at the end of the connecting flange; a movable support plate is rotatably assembled on the end of each set of hot pressing forming rollers away from the connecting flange, and the two movable support plates are respectively locked to the inside of the frame housing by four sets of second fastening bolts.

[0009] The outer wall of the frame housing and the outer side of the first mounting bracket are fixedly welded to a second support mounting plate. A hot melt raw material storage box is fixedly mounted on the top surface of the second support mounting plate. The side wall of the hot melt raw material storage box is connected to a raw material conveying pipeline. A conveying pump is fixedly assembled in the middle of the raw material conveying pipeline section. The end of the raw material conveying pipeline away from the storage box is connected to the shoe material hot pressing extrusion chamber. A mechanical liquid level detector is fixedly installed on the inner wall of the shoe material hot pressing extrusion chamber. A long strip-shaped shoe material discharge mold is opened on the bottom wall of the hot pressing extrusion chamber. Three sets of support connecting columns are vertically fixed on the top surface of the hot pressing extrusion chamber. The three sets of support connecting columns are evenly arranged in a ring along the top surface of the extrusion chamber. The lower end of the support connecting column is rigidly connected to the top surface of the hot pressing extrusion chamber, and the upper end of the support connecting column is locked and fixed to the top and bottom surfaces of the frame housing.

[0010] Preferably, the frame housing is a closed rectangular metal housing with a hollow interior forming a multi-station processing cavity. The sliding grooves on the left and right side walls of the housing are through-type long grooves that extend vertically along the housing. The width of the sliding grooves is adapted to the lateral sliding stroke of the first mounting frame and the movable support plate.

[0011] Preferably, the first mounting bracket is an L-shaped metal bent plate structure. The horizontal section of the first mounting bracket is equipped with a drive motor, and the vertical section is attached to the outer wall of the frame housing and slides laterally along the slide groove. The first fastening bolt passes through the vertical section of the first mounting bracket and the side wall of the frame housing to achieve positioning and locking.

[0012] Preferably, the movable support plate is a rectangular flat plate structure with a roller shaft rotation through hole. The end of the hot-pressed forming roller is embedded in the through hole to achieve rotational engagement. The movable support plate slides synchronously along the slide groove along the inner wall of the frame housing. The second fastening bolt passes through the movable support plate and the frame housing to complete the position fixation.

[0013] Preferably, the three sets of support connecting columns have the same length and outer diameter, the included angle between the centers of two adjacent sets of support connecting columns is 120°, and threaded holes are opened at both the upper and lower ends of the support connecting columns. The upper threaded hole is locked with the bolts on the top wall of the frame housing, and the lower threaded hole is locked with the flange on the top surface of the hot pressing extrusion chamber.

[0014] Preferably, the outline of the hot press plate matches the outline of the shoe material outlet mold, the vertical projection of the hot press plate completely covers the long strip shoe material outlet mold, and multiple parallel anti-slip embossing lines are provided on the bottom surface of the hot press plate.

[0015] Preferably, the top opening of the finished material storage box is directly below the shoe material discharge mold opening, the finished material storage box and the bottom of the frame housing are integrally welded, and the inner cavity of the storage box is provided with layered partitions.

[0016] Preferably, the raw material conveying pipeline is a high-temperature resistant metal flexible hose, and the two ends of the pipeline are respectively connected to the hot melt raw material storage box and the shoe material hot pressing extrusion cavity by flange sealing. The conveying pump body is fixedly clamped in the middle section of the outer wall of the pipeline, and a sealing gasket is provided between the pump body and the pipeline.

[0017] The technical effects and advantages of this invention are as follows: 1. The present invention comprises a frame housing, a slide groove, a first mounting frame, a first fastening bolt, a drive motor, a drive spindle, a connecting flange, a hot pressing forming roller, a movable support plate, and a second fastening bolt to form a sliding adjustable multi-station hot pressing roller assembly. The first mounting frame and the movable support plate can slide synchronously laterally along the slide groove. After sliding into place, they are locked and fixed by bolts. The pressing gap between the two sets of hot pressing forming rollers can be freely adjusted according to the thickness of the shoe material and the shoe size specifications. One set of equipment can complete the hot pressing forming of shoe materials of various thicknesses such as shoe toe, shoe lining, and midsole. Multi-station synchronous processing greatly improves the versatility of the equipment. There is no need to replace the entire mold frame, which shortens the disassembly and assembly time for shoe material change processing. 2. This invention is equipped with a hot-melt raw material storage box, conveying pipeline, conveying pump, hot-pressing extrusion chamber, and mechanical liquid level detector to form a purely mechanical linkage automatic feeding mechanism. The liquid level detector is connected to the conveying pump via mechanical swing rod and connecting rod. When the raw material in the extrusion chamber is insufficient, the mechanical structure automatically starts the pump to replenish the material. After the raw material is full, the machine automatically stops. No manual supervision or material replenishment is required throughout the process, eliminating the need for manual periodic inspection and material replenishment, thus reducing labor costs. The entire feeding structure has no electronic components, making it less prone to damage in the high-temperature and dusty processing environment of shoe materials, and the equipment has stronger stability during continuous operation.

[0018] 3. This invention employs three sets of evenly distributed annular support connecting columns to suspend and fix the hot-pressing extrusion chamber. The three sets of connecting columns are arranged in a 120° annular pattern, vertically bearing the downward pressure load of the hot-pressing platen. The extrusion chamber is subjected to uniform force, and the pressure is consistent along the entire length of the elongated discharge die. The edges, corners, and concave and convex contours of irregularly shaped curved shoe materials can be fully hot-pressed and shaped, effectively reducing defects such as shoe material wrinkles, poor adhesion, and localized pressure deficiencies, and improving the yield rate of shoe material molding. The split-type threaded locking connecting columns can be disassembled and installed individually, making the cleaning of accumulated glue and waste materials inside the extrusion chamber convenient and reducing the difficulty of equipment maintenance.

[0019] 4. The bottom of the frame housing is equipped with an integrated finished product collection and storage box. The shoe materials processed at the discharge die directly fall into the inner cavity of the storage box for centralized storage, eliminating the need for manual real-time picking of finished products. This avoids shoe materials from scattering on the ground and causing scratches and deformation, reduces secondary sorting and transfer processes, and is suitable for continuous, fully automated, multi-station processing production on assembly lines.

[0020] 5. The top of the equipment is equipped with a cylinder-driven telescopic top shaft and a hot press plate, which vertically and rigidly extrudes the hot melt shoe material raw material. It works in conjunction with the adjustable gap double hot press forming rollers below to complete the secondary roll forming. The two-stage mechanical pressing structure improves the tightness of the internal material bonding of the shoe material. After forming, the shoe material has higher structural strength and meets the requirements of wear-resistant and bend-resistant shoe materials. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] This invention discloses a fully automatic multi-station shoe material hot pressing forming processing equipment. The main supporting structure is a frame shell 1, which is welded from thickened steel plate and is a closed rectangular hollow shell. The hollow area inside the shell serves as the hot pressing processing chamber for the shoe materials at multiple stations, isolating it from external dust and high temperatures and protecting the internal transmission and extrusion components. A set of sliding grooves 2 are symmetrically opened on the left and right outer walls of the frame shell 1. The sliding grooves 2 are through-slots extending vertically along the shell. The width of the sliding grooves 2 matches the lateral sliding stroke of the first mounting frame 3 and the movable support plate 9. The sliding grooves 2 provide mechanical guide tracks for the lateral sliding adjustment of the two sets of hot pressing forming rollers 8.

[0029] Two sets of first mounting brackets 3 are symmetrically arranged on the outer wall of the frame housing 1 and the outer side of the slide groove 2. The first mounting brackets 3 are integrally formed from L-shaped bent steel plates. The vertical section fits against the outer wall of the frame housing 1, and the horizontal section extends upward to support the drive motor 5. The vertical sections of the two sets of first mounting brackets 3 are respectively provided with two sets of threaded through holes. The corresponding positions of the side wall of the frame housing 1 are provided with matching threaded holes. The first fastening bolt 4 passes through the through hole of the vertical section of the first mounting bracket 3 and the threaded hole of the frame housing 1 to achieve threaded locking. After the first fastening bolt 4 is loosened, the first mounting bracket 3 can slide laterally along the slide groove 2. After locking, the position of the mounting bracket is fixed.

[0030] A set of drive motors 5 are rigidly fixed on the top surface of the horizontal section of the first mounting frame 3 of each group. The output end of the drive motor 5 is fitted with a drive spindle 6, and the drive spindle 6 is rigidly connected to the output shaft of the drive motor. A connecting flange 7 is fixedly welded to the end face of the drive spindle 6 away from the drive motor 5. The connecting flange 7 adopts a circular flange structure, and multiple rings of fixing screw holes are opened on the end face of the flange. The outer end face of the connecting flange 7 is rigidly locked to the end of the hot pressing forming roller 8. When the drive spindle 6 rotates, it synchronously drives the hot pressing forming roller 8 to rotate circumferentially through the connecting flange 7.

[0031] Two sets of hot-press forming rollers 8 are mounted on the other end away from the connecting flange 7, and each set of movable support plates 9 is rotatably assembled. The movable support plate 9 is a rectangular steel plate with a circular roller shaft rotation through hole in the center of the plate. The roller shaft at the end of the hot-press forming roller 8 is embedded in the through hole, and the two are fitted with a clearance to achieve rotation. The movable support plate 9 is arranged against the inner wall of the frame housing 1 and can slide laterally along the slide groove 2 synchronously with the first mounting frame 3. Each movable support plate 9 has threaded holes at its four corners, and the inner wall of the frame housing 1 has matching threaded holes at corresponding positions. The second fastening bolt 10 passes through the movable support plate 9 and is threadedly locked to the frame housing 1 to achieve mechanical locking and positioning after the movable support plate 9 slides into place.

[0032] The bottom of the frame housing 1 is made of an integrally welded finished material storage box 11. The open area at the top of the finished material storage box 11 is vertically facing the bottom of the shoe material discharge mold 21. The shoe material that has been hot-pressed falls directly into the inner cavity of the finished material storage box 11 from the discharge mold 21. The storage box 11 is equipped with multiple layered compartments, which can store shoe materials of different specifications and processes in different areas to avoid the shoe materials squeezing and scratching each other. The bottom of the storage box is equipped with a detachable unloading door to facilitate the batch transfer of processed shoe materials.

[0033] A hot-pressing drive cylinder 12 is vertically fixed at the center of the top surface of the frame housing 1. The cylinder body of the hot-pressing drive cylinder 12 is fixed vertically upward. A telescopic top shaft 13 is telescopically assembled inside the cylinder. The telescopic top shaft 13 slides vertically up and down along the cylinder axis. The lower end of the telescopic top shaft 13 extends out of the cylinder and is rigidly connected to the hot-pressing plate 14 at its end face. The hot-pressing plate 14 is a rectangular metal plate. The bottom contour of the plate is perfectly matched with the long contour of the shoe material outlet 21. Multiple parallel anti-slip embossings are processed on the bottom surface of the plate. During the pressing process, the contact friction with the hot-melt shoe material increases, preventing the material from overflowing to the side.

[0034] A second support mounting plate 15 is fixedly welded to the outer wall of the frame housing 1 and the outer side of the first mounting bracket 3. The second support mounting plate 15 is a horizontal steel plate bracket, and the plate surface is welded and fixed perpendicularly to the side wall of the frame housing 1. A hot melt raw material storage box 16 is rigidly mounted on the top surface of the second support mounting plate 15. The hot melt raw material storage box 16 is a sealed high-temperature resistant metal box used to store hot melt resin, hot melt adhesive and other raw materials required for hot pressing molding of shoe materials. A sealed feeding port is opened on the top surface of the box to replenish hot melt raw materials in batches.

[0035] The bottom of the outer wall of the hot melt raw material storage tank 16 is connected to the raw material conveying pipeline 17. The raw material conveying pipeline 17 is made of high-temperature resistant stainless steel flexible tubing. Both ends of the pipeline are connected to the hot melt raw material storage tank 16 and the shoe material hot pressing extrusion chamber 19 by flange sealing structures. The conveying pump body 18 is clamped and fixed in the middle of the outer wall of the raw material conveying pipeline 17. A high-temperature resistant sealing gasket is installed at the connection between the pump body and the pipeline to prevent leakage of hot melt raw materials. The mechanical transmission lever of the conveying pump body 18 is mechanically connected to the mechanical liquid level detector 20. There is no electrical signal interaction. The pump body start and stop control is achieved by relying on the pure mechanical structure.

[0036] The raw material conveying pipeline 17 is sealed and connected to the shoe material hot pressing extrusion chamber 19 at the end flange away from the hot melt raw material storage box 16. The shoe material hot pressing extrusion chamber 19 is a closed, high-temperature resistant, pressure-bearing chamber that contains liquid hot melt shoe material raw materials to be hot pressed. A mechanical liquid level detector 20 is vertically fixed on the inner wall of the extrusion chamber 19. The liquid level detector 20 has a built-in float that can swing up and down. The float extends to the side of the conveying pump body 18 through an external mechanical linkage. The float swings up and down with the liquid level. When the liquid level is lower than the set threshold, the float presses down the pump body lever, and the conveying pump body 18 is started by mechanical transmission. After the liquid level rises to the upper limit height, the float lifts the float and disengages from the lever, and the conveying pump body 18 stops by mechanical reset structure.

[0037] The bottom wall of the hot pressing extrusion chamber 19 for shoe materials has a long strip-shaped shoe material discharge die 21. The discharge die 21 extends horizontally, and the long strip cross-section of the die matches the basic forming contour of various shoe materials. When the hot pressing plate 14 presses down, the hot melt raw material inside the extrusion chamber is extruded downwards at a uniform speed along the discharge die 21 to form the material.

[0038] Three sets of support connecting columns 22 are vertically fixed on the top surface of the hot pressing extrusion chamber 19 for shoe materials. The outer diameter and length of the three sets of support connecting columns 22 are completely uniform. The three sets of connecting columns are evenly arranged in a ring along the top surface of the extrusion chamber 19, and the included angle between the centers of two adjacent sets of support connecting columns 22 is 120°. The upper and lower ends of the support connecting columns 22 are provided with internal threaded holes. The lower threaded hole is locked with the flange bolt on the top surface of the extrusion chamber 19, and the upper threaded hole extends upward and is rigidly locked with the bolt on the bottom surface of the top wall of the frame housing 1. The three sets of support connecting columns 22 jointly bear all the extrusion force generated by the hot pressing plate 14 pressing down, so as to achieve all-round balanced force on the extrusion chamber.

[0039] Overall equipment assembly process Step 1: Assemble the main frame. Machin the slide groove 2 onto the left and right side walls of the frame housing 1. Weld and fix the finished material storage box 11 to the bottom of the frame housing 1 to complete the assembly of the main load-bearing structure of the frame. Step 2: Assemble the multi-station hot press roller assembly. Place the two sets of first mounting brackets 3 against the outer wall of the slide groove 2 of the machine frame housing 1, insert the first fastening bolts 4 for pre-tightening, fix the drive motor 5 on the top surface of the first mounting bracket 3, assemble the drive spindle 6 with the connecting flange 7, lock one end of the hot press forming roller 8 to the connecting flange 7, and embed the other end into the rotating through hole of the movable support plate 9. The movable support plate 9 is attached to the inner wall of the housing and pre-locked by the second fastening bolts 10. Step 3: Assemble the top hot press drive assembly. Fix the hot press drive cylinder 12 to the center of the top surface of the frame housing 1. Install the telescopic top shaft 13 inside the cylinder. Assemble the hot press plate 14 at the lower end of the telescopic top shaft. Step 4: Assemble the raw material conveying mechanism. Weld the second support mounting plate 15 to the outside of the frame housing 1. Fix the hot melt raw material storage box 16 on the plate. Connect the storage box and the shoe material hot pressing extrusion cavity 19 at both ends of the raw material conveying pipeline 17. Fix the conveying pump body 18 in the middle section of the pipeline. Assemble the mechanical liquid level gauge 20 on the inner wall of the extrusion cavity. Connect the mechanical linkage of the liquid level gauge to the lever of the conveying pump body. Step 5: Assembly of extrusion chamber support. Tighten the lower ends of the three sets of support connecting columns 22 to the top surface of the shoe material hot pressing extrusion chamber 19 with threads, and tighten the upper ends of the support connecting columns upward to the top wall of the frame housing 1 to complete the hoisting of the extrusion chamber ring support. Step 6: Overall debugging. Loosen the first fastening bolt 4 and the second fastening bolt 10. Slide the two sets of hot-press forming rollers 8 laterally along the slide groove 2. Adjust the roller gap according to the thickness of the shoe material to be processed. After the gap meets the standard, tighten all bolts. Add hot-melt shoe material to the hot-melt raw material storage box 16. Debug the mechanical linkage stroke of the liquid level gauge. Test the automatic start and stop mechanical action of the conveying pump. Debug the vertical downward pressing stroke of the cylinder driving the hot-press plate. Confirm that the material is discharged smoothly from the discharge mold. Complete the equipment assembly and debugging.

[0040] Work process When the equipment is put into fully automatic multi-station hot pressing processing of shoe materials, first loosen the first fastening bolt 4 and the second fastening bolt 10, push the first mounting frame 3 and the movable support plate 9 to slide laterally along the slide groove 2, adjust the pressing gap between the two sets of hot pressing forming rollers 8, and after the gap matches the thickness of the current batch of shoe materials, tighten the first fastening bolt 4 and the second fastening bolt 10 respectively to lock all sliding components.

[0041] Hot melt raw materials are pre-filled into the hot melt raw material storage tank 16, and the raw material conveying pipeline 17 connects the storage tank to the shoe material hot pressing extrusion chamber 19. The mechanical liquid level detector 20 inside the extrusion chamber 19 monitors the liquid level of the hot melt raw materials in real time through a float. When the liquid level is lower than the set minimum height, the float sinks and drives the swing arm to press down the mechanical lever of the conveying pump body 18. The conveying pump body 18 is started by mechanical linkage, and the pump body pumps the hot melt raw materials in the storage tank 16 into the shoe material hot pressing extrusion chamber 19 through the conveying pipeline 17. When the liquid level rises to the upper limit height, the float rises, the swing arm disengages from the pump body lever, and the conveying pump body 18 mechanically resets and stops. The entire process relies on the mechanical structure to automatically replenish the raw materials without manual intervention.

[0042] The hot-press drive cylinder 12 is activated, which drives the telescopic top shaft 13 to push the hot-press plate 14 vertically downward. The hot-press plate 14 presses down and extrudes the liquid hot-melt raw material inside the hot-press extrusion chamber 19 of the shoe material. Under the pressure of the plate, the raw material is extruded downward at a uniform speed along the bottom long strip shoe material discharge die 21 to form a continuous strip shoe material blank. Three sets of annularly evenly arranged support connecting columns 22 synchronously bear the downward pressure load of the plate, so the extrusion chamber 19 is uniformly stressed as a whole, the extrusion pressure of the discharge die 21 is consistent along the entire line, the blank thickness is uniform, and there are no local material shortages or wrinkles.

[0043] The two drive motors 5 are started simultaneously, and the drive motors 5 drive the drive spindle 6 and the connecting flange 7 to rotate synchronously. The two sets of hot pressing forming rollers 8 are driven by the motor to rotate in opposite directions in a circumferential direction. They clamp the strip-shaped shoe material blanks extruded from the discharge die 21 from the upper and lower sides, and complete the secondary rolling and shaping by relying on the gap between the rollers, so as to accurately control the thickness of the formed shoe material. After the shoe material is pressed and shaped by the double rollers, it continues to fall downward and falls directly into the integrated finished product collection and storage box 11 at the bottom of the frame housing 1 for centralized storage. The processing personnel only need to open the unloading door of the storage box periodically to transfer the finished products, so as to realize fully automatic continuous multi-station hot pressing forming processing.

[0044] After processing, loosen the first fastening bolt 4 and the second fastening bolt 10, slide along the slide groove 2 to adjust the gap between the two sets of hot pressing forming rollers 8, and switch to process shoe materials of different thicknesses and types; the single support connecting column 22 can be disassembled separately, making it easy to open the shoe material hot pressing extrusion chamber 19 to clean the internal glue and waste, and the equipment maintenance and operation are simple.

[0045] This invention is not limited to the above-described embodiments. Equivalent structural substitutions can be made without departing from the core mechanical innovation of this invention. The slide 2 can be replaced by a T-slot, dovetail slot, or other guide sliding groove, all of which are equivalent mechanical structures for adjusting the sliding clearance of the slide; The mechanical level gauge 20 can be replaced by a weighted mechanical level triggering mechanism or a float-type mechanical linkage level assembly. As long as it relies on mechanical transmission to link the pump body, it falls within the protection scope of this invention. The supporting connecting column 22 can be adjusted to a four-column ring arrangement. As long as a mechanical structure with multiple columns uniformly supporting the extrusion cavity is adopted, it is an equivalent replacement of the ring support innovation point of this invention. The first fastening bolt 4 and the second fastening bolt 10 can be replaced with quick-release locking handles and eccentric locking buckles, which are simple equivalent replacements of the sliding component locking structure.

[0046] All equipment based on the improved mechanical structure of this invention that does not add intelligent electronic control or software control systems, but only achieves fully automatic multi-station hot pressing molding of shoe materials through mechanical transmission, sliding locking, and ring support structure, falls within the protection scope of this invention.
