Description

Technical Field

[0001] The invention relates to the field of sole forming machines, in particular to a sole side-shift forming machine. Background Art

[0002] TPU foam particles are microporous materials with stable structures obtained by foaming TPU raw materials by physical or chemical methods. Their diameter is generally between 5mm and 7mm. Foam materials have their own unique advantages, including: 1) excellent impact load resistance. When foam plastics are impact compressed, the internal bubbles play a role of compression rebound, consuming the impact energy, so it has better buffering and shock absorption function; 2) excellent thermal insulation performance. The bubbles inside the polymer are gas, but the heat transfer coefficient of gas is generally lower than that of polymer. At the same time, the pores can prevent air convection, so foam plastics have thermal insulation function; 3) high specific strength. The ratio of material strength to material relative density is called specific strength. The strength of foam plastics is slightly lower than that of raw materials, but the density is greatly reduced. Therefore, foam plastics usually have a large specific strength.

[0003] The process used in the existing TPU application in shoe material production is the TPU foaming process. The so-called "TPU foaming process" is actually like popcorn. TPU is made into granules. You can think of these granules as old corns, and then throw them into a machine, which is similar to a popcorn machine. After high temperature and high pressure, these corns become popcorn. Then, the steam molding process is used to process about 2,000 popcorn granules into the required sole shape. In this process, the outermost layer of the foamed particles is slightly melted and adhered into a stable shape. At the same time, the internal pore structure is not affected, so that the formed popcorn sole has many advantages such as soft texture, good elasticity, good cushioning performance, low pressure energy loss, good durability, and good thermal insulation performance. Its surface presents a granular appearance and texture, which is favored by many consumers.

[0004] The existing Chinese invention patent with publication number CN221659904U discloses a forming machine flipping structure of a vertical and horizontal multifunctional integrated forming machine. The flipping mechanism drives the flipping frame to switch between vertical and horizontal. When the flipping frame is vertical, workers can easily put in inserts to process the soles with bottom plates and or carbon plates, solving the problem of deformation and bending of the guide shaft in the previous horizontal structure mold closing process, thereby affecting the service life. When the flipping frame is flipped by the flipping mechanism and changed to horizontal, the flipping frame is parallel to the frame. At this time, the sole forming device is directly demolded, and the formed sole falls to the bottom of the frame and is transported to the frame by the subsequent conveyor belt, so as to achieve rapid unloading and thus improve production efficiency. The whole process switches between horizontal and vertical states, which improves the service life and processing efficiency of the equipment, and processes the soles with bottom plates and or carbon plates in a low-cost manner, thereby improving the diversity of product processing of the equipment.

[0005] However, the above technical solution also has the following defects: 1. When the sole forming machine is processing the sole with inserts, it is necessary to wait until the previous group of soles is processed and demolded before inserts can be placed one by one. When placing the inserts, the entire machine needs to wait until the inserts are placed before continuing to mold a new group of soles. This makes the entire equipment unable to process and generate continuously, and the efficiency is low.

[0006] 2. When placing inserts, the staff needs to reach between the movable mold and the fixed mold to take out the products and place the parts. However, there is a risk of the fixed mold and the movable mold being closed at this time. If a failure occurs at this time, it is easy to cause personal injury.

[0007] 3. The sole forming machine needs to switch between vertical and horizontal processing when forming each set of soles, which makes the whole equipment consume a lot of energy and the processing time is too long.

[0008] Therefore, it is urgent to design a sole forming machine that can realize one work and one wait, portable installation of inserts, convenient unloading, and does not require frequent switching to improve the sole forming efficiency. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a sole side shift forming machine in view of the deficiencies of the above-mentioned prior art.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shoe sole side-shifting forming machine, comprising a frame and a shoe sole forming device installed in the frame, characterized in that: the shoe sole forming device comprises a forming frame, a fixed die set and a movable die set relatively arranged on the forming frame, and a clamping mechanism driving the movable die set to approach or move away from the fixed die set, the forming frame comprises a lateral shifting bracket and a driving bracket for support, and a plurality of guide shafts passing through the lateral shifting bracket and the driving bracket, a movable die frame is arranged on the side of the movable die set facing the fixed die set, the fixed die set comprises a first fixed die frame and a second fixed die frame which are arranged identically on the left and right sides and both face the movable die frame, The transverse moving bracket is provided with a plurality of hinge components hinged with the frame, and the frame is provided with a tilting driving mechanism at the driving bracket corresponding to the frame, which drives the forming frame to rotate with the hinge component as the fulcrum, and the tilting driving mechanism is used to tilt the openings of the first fixed mold frame and the second fixed mold frame upward, and the left and right sides of the forming frame corresponding to the movable mold group are provided with discharge stations, and the fixed mold group can slide horizontally left and right along the transverse moving bracket, when the first fixed mold frame is opposite to the movable mold frame, the second fixed mold frame stays at the discharge station on one side of the movable mold group, and when the second fixed mold frame is opposite to the movable mold frame, the first fixed mold frame stays at the discharge station on the other side of the movable mold group.

[0011] With the above technical solution, the transverse moving bracket, the driving bracket and the guide shaft constitute the forming frame, the forming frame is arranged in the frame and the tilting of the forming frame is controlled by the tilting driving mechanism, the movable die set can slide on the guide shaft, and the mold closing and opening are realized through the mold closing mechanism and the fixed die set, the fixed die set is slidingly arranged on the transverse moving bracket, and can be pushed manually or electrically to slide horizontally left and right along the transverse moving bracket, so that the two fixed die frames can be molded with the movable die frame respectively, so that when a fixed die frame is in the molding work, the other fixed die frame can allow the worker to place the insert on the side, and one end of the forming frame is hinged to the frame through the hinge assembly, and the other end is driven by the tilting driving mechanism to realize the 0-45° tilting action. Since the fixed die set is arranged close to the transverse moving bracket Articulated assembly, when the forming frame is tilted, the opening surface of the fixed die group will tilt upward. At this time, the workers at the unloading stations on both sides can safely and conveniently put the inserts into the opening surface of the fixed die group without falling out. After the unloading is completed, since the forming frame is only partially tilted, the soles can be easily pushed out of the fixed die group and fall onto the conveyor belt below for output. The tilting drive mechanism can conveniently adjust the tilt angle of the forming frame to adapt to the processing environment of different soles. For example, when processing soles that do not require inserts, it is adjusted to 0°. The entire mechanism enables the molding machine to achieve one work and one wait, that is, to achieve continuous production and improve production efficiency, and effectively avoid employees placing inserts between the fixed die group and the movable die group, ensuring safe operation and avoiding the problem of inserts easily falling out.

[0012] The above-mentioned sole lateral shift forming machine can be further configured as follows: the fixed die group is slidably connected to the transverse shift bracket through a slider rail structure, and the forming frame is provided with a lateral shift driving mechanism corresponding to the fixed die group, which drives the first fixed die frame and the second fixed die frame on the fixed die group to slide back and forth along the transverse shift bracket, and the lateral shift driving mechanism includes a transverse shift cylinder arranged on the transverse shift bracket, the output end of the transverse shift cylinder is connected to the fixed die group, and the transverse shift cylinder is arranged parallel to the slider rail structure.

[0013] By adopting the above technical scheme, the fixed die group is a rectangular plate-shaped metal, the rear of which is slidably connected to the transverse moving bracket through a slider rail structure, and two identical fixed die frames are installed in the front. The fixed die group is driven to move laterally through the side shifting drive mechanism, and different fixed die frames are switched to correspond to the movable die frames, thereby ensuring the stability and reliability of the fixed die group during lateral sliding and avoiding deviation. The side shifting drive mechanism includes a transverse moving cylinder, and its output end is connected to the fixed die group to realize the automatic and rapid transverse movement of the fixed die group, saving manpower, and enabling the fixed die group to achieve rapid and accurate transverse movement through the side shifting drive mechanism.

[0014] The above-mentioned sole lateral shift forming machine can be further configured as follows: at least one lateral shift limit block is provided in the moving direction of the lateral shift bracket corresponding to the fixed die group; when the fixed die group and the lateral shift limit block are limited against each other, the first fixed die frame or the second fixed die frame is provided corresponding to the movable die frame; and a pressure sensor or a displacement sensor is provided at the lateral shift cylinder.

[0015] By adopting the above technical scheme, the lateral shift limit block limits the moving range of the fixed die group to ensure that after one end of the fixed die group is against the lateral shift limit block, one of the fixed die frames can be correctly aligned with the movable die frame. A pressure sensor or a displacement sensor is provided on the transverse shift cylinder. When a pressure sensor is used, it is used to monitor the pressure in the hydraulic cylinder to ensure that the system operates within a safe pressure range. When the fixed die group is against the lateral shift limit block, the pressure of the pressure sensor increases, a judgment is made, and then the machine automatically stops. When a displacement sensor is used, a magnetostrictive displacement sensor is preferably used to directly measure the stroke of the hydraulic cylinder to provide absolute position measurement, so there is no need for repeated settings, and it has good seismic and impact resistance. The above sensor transmits electrical signals to the control system, which is convenient for accurate control of the lateral shift stability switching of the fixed die group.

[0016] The above-mentioned sole lateral shift forming machine can be further configured as follows: one end of the fixed die group corresponding to the lateral shift cylinder is provided with a lateral shift driving seat fixedly connected to the fixed die group, the output end of the lateral shift cylinder is connected to the lateral shift driving seat, the number of the lateral shift limit blocks is 2, and they are respectively the first lateral shift limit block and the second lateral shift limit block, the first lateral shift limit block and the second lateral shift limit block are respectively arranged at the two ends of the travel trajectory of the lateral shift driving seat, when the lateral shift driving seat abuts against the first lateral shift limit block, the first fixed die frame and the movable die frame are arranged oppositely, and when the lateral shift driving seat abuts against the second lateral shift limit block, the second fixed die frame and the movable die frame are arranged oppositely.

[0017] By adopting the above technical solution, a first lateral shift limit block and a second lateral shift limit block are arranged on the transverse shift bracket, wherein the first lateral shift limit block is arranged in the middle position of the transverse shift bracket, and the second lateral shift limit block is arranged at the side position of the transverse shift bracket, and the transverse shift drive seat is arranged between the first lateral shift limit block and the second lateral shift limit block, so as to ensure that the fixed mold group always moves between the first lateral shift limit block and the second lateral shift limit block, and after they are offset, the first and second fixed mold frames can be accurately aligned with the movable mold frame respectively.

[0018] The above-mentioned sole side-shift forming machine can be further configured as follows: the mold clamping mechanism includes a plurality of mold clamping cylinders arranged on the driving bracket corresponding to the movable mold group, the output end of the mold clamping cylinder is connected to the movable mold group, and the movable mold group is driven by the mold clamping cylinder to approach or move away from the fixed mold group along the guide shaft to complete the mold opening or mold closing action.

[0019] By adopting the above technical solution, the mold clamping mechanism controls the movable mold group to move along the guide shaft through the guide shaft and the mold clamping cylinder to achieve mold clamping and mold opening.

[0020] The above-mentioned sole side-shift forming machine can be further configured as follows: the tilting drive mechanism includes a pushing cylinder and a pushing-up hinge seat arranged on both sides of the driving bracket, one end of the pushing cylinder is hinged to the pushing-up hinge seat, and the other end is hinged to the driving bracket, and the forming frame is provided with a state locking mechanism for maintaining or unlocking the current tilting state of the forming frame.

[0021] By adopting the above technical scheme, one end of the pushing cylinder in the tilting drive mechanism is hinged to the pushing articulated seat, and the other end is hinged to the forming frame, thereby avoiding angle interference during the tilting process. The forming frame is pushed closer to or away from the pushing articulated seat by the extension and retraction of the cylinder to achieve the tilting action, and the height of the forming frame is accurately controlled to control the tilting angle to adapt to the processing environment of different soles, and the tilting state of the forming frame is maintained or unlocked by the state locking mechanism. The whole mechanism enables the forming machine to achieve a single-standby and portable installation of inserts, and to facilitate unloading, and solves the problems of excessive energy consumption, low efficiency and safety hazards caused by frequent switching between vertical and horizontal types in the prior art.

[0022] The above-mentioned sole lateral shift forming machine can be further configured as follows: the state locking mechanism includes a locking frame arranged on the side of the driving bracket, a plurality of positioning holes arranged on the driving bracket corresponding to the locking frame, and a pin arranged on the locking frame for inserting into or disengaging from at least one of the positioning holes, and the positioning holes and the hinge assembly are axially distributed around the outer surface of the driving bracket as a fulcrum.

[0023] By adopting the above technical solution, the tilting state of the forming frame is locked or unlocked by inserting or disengaging the pin from the positioning hole, wherein the pin can be inserted and pulled out manually or automatically, thereby ensuring stable processing after tilting and preventing the forming frame from falling due to cylinder failure. That is, multiple positioning holes are distributed around the outer surface of the driving bracket, so that the forming frame can be locked at multiple tilting angles, increasing the flexibility and stability of use.

[0024] The above-mentioned sole side-shift forming machine can be further configured as follows: a locking cylinder is provided on the locking frame, the push-up hinge seat and the locking cylinder are both arranged at the end of the locking frame, the pin is installed at the output end of the locking cylinder, and the pin is driven by the locking cylinder to penetrate into or disengage from the positioning hole, and a conveyor belt is provided at the bottom of the forming frame.

[0025] By adopting the above technical solution, the push-up hinge seat and the locking cylinder are arranged together at the end of the locking frame, which simplifies the structural design and facilitates installation and maintenance. The locking cylinder drives the pin to enter or disengage from the positioning hole, and the movement of the pin is controlled by the telescopic action of the cylinder to achieve automatic locking and unlocking.

[0026] The above-mentioned sole lateral shift forming machine can be further configured as follows: the hinged assembly includes a frame seat fixedly mounted on the frame, a forming seat fixedly mounted on the bottom of the transverse shift bracket, a rotating main shaft, and a frame sleeve and a forming sleeve sleeve sleeved outside the rotating main shaft, the outer surface of the frame sleeve is fixedly connected to the frame seat, and the outer surface of the forming sleeve is fixedly connected to the transverse shift bracket.

[0027] Using the above technical solution, the articulated assembly includes a frame seat, a molding seat, a rotating spindle, a frame sleeve and a molding sleeve. Through the cooperation of these components, smooth rotation between the molding frame and the frame is achieved, providing a stable articulated structure, and ensuring the smoothness and durability of the tilting of the molding frame.

[0028] The above-mentioned sole side-shift forming machine can be further configured as follows: a frame bearing is provided between the rotating main shaft and the frame sleeve, a frame oiling head connected to the rotating main shaft is provided on the frame sleeve, a plurality of oil holes are provided on the frame bearing, a frame shaft cover fixedly connected to the frame sleeve is provided on one side of the rotating main shaft, a molding bearing is provided between the rotating main shaft and the molding sleeve, a molding oiling head connected to the rotating main shaft is provided on the molding sleeve, a plurality of oil holes are provided on the molding bearing, a molding shaft cover fixedly connected to the molding sleeve is provided on one side of the rotating main shaft, an isolation ring seat is provided on the outer circumferential surface of the rotating main shaft to separate the frame bearing and the molding bearing, and isolation ring grooves with stepped cross-sections are provided on the frame and the molding sleeve corresponding to the isolation ring seats.

[0029] By adopting the above technical scheme, a bearing is sleeved on the outside of the rotating main shaft to replace the rotating main shaft and the sleeve to rotate against each other, thereby reducing friction and prolonging service life. By arranging an oiling head on the outside of the sleeve, a worker can directly inject lubricating oil into the sleeve through the oiling head from the outside. The lubricating oil passes through multiple oil holes on the bearing and fills the entire sleeve, making the forming frame rotate more smoothly, thereby improving the working efficiency and service life of the equipment. The setting of the shaft cover will facilitate the installation of the hinge assembly and improve the sealing, and reduce lubricating oil leakage. The isolation ring seat on the outer circumference of the rotating main shaft separates the frame bearing from the forming bearing. The design of the isolation ring groove improves the sealing of the hinge assembly, reduces lubricating oil leakage, and prolongs service life. The conveyor belt is set to receive the demolded soles after molding and directly send them out of the frame, thereby improving processing efficiency.

[0030] The beneficial effects of the present invention are: 1. Improve production efficiency: By realizing the left and right lateral sliding of the fixed die group, when one fixed die frame is closing the mold with the movable die frame, the other fixed die frame can place the inserts at the same time, realizing a continuous production mode of one work and one waiting, which significantly improves production efficiency.

[0031] 2. Improved operational safety: Since the fixed die set can slide laterally, workers can safely place inserts on the side, and at the same time, they can prevent the inserts from falling after tilting. There is no need to operate between the movable die set and the fixed die set, which greatly reduces the risk of personal injury caused by extrusion during mold closing.

[0032] 3. Precise control and stability: By installing a pressure sensor or displacement sensor at the transverse cylinder, the movement and positioning of the fixed die set can be accurately controlled to ensure the correct alignment of the fixed die frame and the movable die frame, thereby improving the molding accuracy and stability.

[0033] 4. Flexible production adaptability: Through the tilting drive mechanism and state locking mechanism, the forming frame can be tilted and adjusted to meet the processing requirements of different soles, increasing the flexibility and adaptability of production.

[0034] 5. Convenient maintenance and operation: The design of the articulated assembly and the rotating spindle makes the rotation between the forming frame and the frame more stable and smooth, which is convenient for maintenance and operation, and also improves the durability and service life of the equipment.

[0035] 6. Improved automation and intelligence levels: Through the cooperation of sensors and control systems, the automatic control of the molding machine is realized, the intelligence level is improved, manual intervention is reduced, and the possibility of operational errors is reduced.

[0036] 7. Convenient finished product output: A conveyor belt is installed at the bottom of the forming frame to facilitate the rapid output of the formed soles, further improving production efficiency and convenience.

A movable die frame 31 is provided on the side of the movable die set 3 facing the fixed die set 2; The fixed die set 4 can slide horizontally left and right along the transverse bracket 21, and the fixed die set 4 includes a first fixed die frame 41 and a second fixed die frame 42 which are both arranged identically at the left and right sides and face the movable die frame 31; A conveyor belt 10, which is arranged below the forming frame 2 and is used to convey the formed soles out of the frame 1; The forming frame 2 has a discharge station A on the left and right sides corresponding to the movable mold group 3, and the fixed mold group 4 can slide horizontally left and right along the transverse bracket 21, so that when the first fixed mold frame 41 is opposite to the movable mold frame 31, the movable mold frame 31 is molded with the fixed mold group 4 for the first time through the mold clamping mechanism, and the second fixed mold frame 42 stays at the discharge station A on the right side of the movable mold group 3; after mold opening, the fixed mold group 4 slides horizontally left and right along the transverse bracket 21, so that when the second fixed mold frame 42 is opposite to the movable mold frame 31, the movable mold frame 31 is molded with the fixed mold group 4 for the second time through the mold clamping mechanism, and the first fixed mold frame 41 stays at the discharge station A on the left side of the movable mold group 3.

[0050] The fixed die group 4 is slidably connected with the transverse moving bracket 21 through a slider rail structure 40. A lateral shift driving mechanism for driving the first fixed die frame 41 and the second fixed die frame 42 on the fixed die group 4 to slide back and forth along the transverse moving bracket 21 is provided at the corresponding fixed die group 4 of the forming frame 2. The lateral shift driving mechanism includes a transverse moving cylinder 211 arranged on the transverse moving bracket 21 and parallel to the slider rail structure 40.

At this time, the signal speed monitored by the magnetostrictive displacement sensor is stable. When the fixed mold group 4 abuts against the second lateral shift limit block 214, it indicates that the second fixed mold frame 42 is already opposite to the movable mold frame 31. At this time, the transverse cylinder 211 cannot be pushed to the bottom, and the displacement signal of the magnetostrictive displacement sensor decreases until it is 0. At this time, it is determined that the transverse shift has been in place, and the transverse cylinder 211 will automatically stop working.

When the molding is completed, the sole is directly The first fixed mold frame 41 is then pushed out by the pushing rod or hooked out by the hook, and falls directly onto the conveyor belt 10 below and is transported out of the frame 1. Then the transverse cylinder 211 starts working to push the fixed mold group 4 to slide along the slider rail structure 40 until the second lateral limit block 214 and the transverse drive seat 212 are limited, and the displacement signal of the magnetostrictive displacement sensor drops to 0. At this time, it is determined that the transverse movement has been in place, and the transverse cylinder 211 will automatically stop working to confirm that the second fixed mold frame 42 with the insert has been pushed to the position corresponding to the movable mold frame 31. Then the mold closing cylinder 41 drives the movable mold group 4 to close the mold along the guide shaft 21 to the fixed mold group 3, and the insert is formed integrally with the sole. At this time, the worker places the insert at the first fixed mold frame 41 of the other right side discharge station A, realizing stable one-work-one-wait, which greatly improves the processing efficiency and safety and convenience.
