Description

Technical Field

[0001] The utility model relates to the field of sole forming machines, in particular to a side shift mechanism for a sole side shift forming machine. Background Art

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

[0003] The existing TPU foaming process used in shoe material production is the TPU foaming process. The so-called "TPU foaming process" is actually like popcorn. The TPU is made into granules. You can think of these granules as grains of old corn, and then thrown into a machine, which is similar to a popcorn machine. After high temperature and high pressure, these corns become popcorn. Then, a steam molding process is used to process about 2,000 popcorn grains 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 utility model patent with publication number CN221659904U discloses a vertical and horizontal multifunctional integrated molding machine with a flipping structure. The flipping mechanism drives the flipping frame to switch between vertical and horizontal modes. When the flipping frame is vertical, workers can conveniently put in inserts and then process soles with bottom plates and or carbon plates, solving the problem that the guide shaft is deformed and bent during 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 mode, the flipping frame is parallel to the frame. At this time, the sole molding device is directly demolded, and the molded sole falls to the bottom of the frame and is transported to the frame by the subsequent conveyor belt, realizing rapid unloading and thus improving production efficiency. The entire process is switched between horizontal and vertical states, which improves the service life and processing efficiency of the equipment, and processes 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:

[0006] 1. When the sole forming machine is processing a sole with an insert, it is necessary to wait until the previous set of soles is processed and demolded before the 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 close the mold to form a new set of soles. This makes the entire equipment unable to process and generate continuously, and the efficiency is low.

[0007] 2. When placing inserts, workers need to reach between the movable die set and the fixed die set to remove the product and place the parts. However, there is a risk of the fixed die set and the movable die set being clamped at this time. If a failure occurs at this time, it is easy to cause personal injury.

[0008] Therefore, there is an urgent need to design a sole forming machine that can realize one work and one wait, is portable and installs inserts, does not need to work in risk areas and improves the sole forming efficiency. Utility Model Content

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a side shift mechanism for a shoe sole side shift forming machine, comprising:

[0011] A forming frame, wherein the forming frame is provided with a transverse support and a driving support for supporting, and a plurality of guide shafts are passed through the transverse support and the driving support;

[0012] The movable die set is movably sleeved on the guide shaft and can be driven by the mold clamping mechanism to slide along the guide shaft to achieve mold closing and mold opening with the fixed die set. A movable die frame is provided on the side of the movable die set facing the fixed die set;

[0013] A fixed die set, which can slide horizontally left and right along the transverse bracket, and includes a first fixed die frame and a second fixed die frame on the left and right sides, both of which are identically arranged facing the movable die frame;

[0014] The fixed die group can slide horizontally left and right along the transverse bracket, so that the first fixed die frame and the second fixed die frame can be arranged opposite to the movable die frame respectively. When the first fixed die frame is opposite to the movable die frame, the second fixed die frame is arranged on the right side of the movable die group, and the movable die frame can be clamped with the first fixed die frame through the clamping mechanism; when the second fixed die frame is opposite to the movable die frame, the first fixed die frame is arranged on the left side of the movable die group, and the movable die frame can be clamped with the second fixed die frame through the clamping mechanism. The forming frame has a discharge station on the left and right sides corresponding to the movable die group.

[0015] By adopting the above technical solution, the transverse moving bracket, the driving bracket and the guide shaft constitute the forming frame, the movable die group can slide on the guide shaft, and the mold closing and opening are realized through the mold closing mechanism and the fixed die group. The fixed die group is slidingly set on the transverse moving bracket and can be pushed manually or electrically to slide left and right along the transverse moving bracket, so that the two fixed mold frames can be respectively closed with the movable mold frame. When one fixed mold frame is in the molding work, the other fixed mold frame is at the discharge station, which makes it convenient for workers to place inserts on the side, realizing one work and one wait, that is, realizing continuous production, improving production efficiency, and effectively avoiding employees placing inserts between the fixed mold group and the movable mold group, ensuring safe operation.

[0017] Using the above technical solution, the fixed die group is a rectangular plate metal, the rear of which is slidably connected to the transverse 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 frame, thereby ensuring the stability and reliability of the fixed die group during lateral sliding, avoiding offset, reducing labor costs, and realizing automated production.

[0018] The above-mentioned side shift mechanism for a sole side shift forming machine can be further configured as follows: the slider rail structure includes two upper and lower side shift rails arranged on the side shift bracket corresponding to the direction of the movable mold frame and a plurality of fixed mold sliders arranged on the fixed mold group and sliding in cooperation with the side shift rails. The fixed mold sliders are mounted on the side shift rails so that the side shift drive mechanism can drive the fixed mold group to move back and forth along the side shift rails.

[0019] By adopting the above technical solution, by setting up upper and lower transverse sliding rails on the transverse bracket and setting a fixed mold slider on the second fixed mold group, the fixed mold slider and the transverse sliding rail are plugged together and slide through the dovetail groove structure to avoid up and down shaking and improve stability.

[0020] The above-mentioned side shift mechanism for a sole side shift forming machine can be further configured as follows: the side shift drive mechanism includes a side shift cylinder arranged on a side shift bracket, the output end of the side shift cylinder is connected to the fixed die set, and the side shift cylinder is arranged parallel to the slider rail structure.

[0021] By adopting the above technical solution, the side shift drive mechanism includes a transverse cylinder, the output end of which 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 side shift drive mechanism to realize rapid and accurate transverse movement of the fixed die group.

[0022] The above-mentioned side shift mechanism for a sole side shift forming machine can be further configured as follows: at least one side shift limit block is provided in the moving direction of the fixed die group corresponding to the transverse shift bracket; when the fixed die group and the side shift limit block are restrained against each other, the first fixed die frame or the second fixed die frame is correspondingly arranged with the movable die frame.

[0023] By adopting the above technical solution, the side shift limit block limits the moving range of the fixed die group, ensuring that after one end of the fixed die group abuts against the side shift limit block, one of the fixed die frames can be correctly aligned with the movable die frame.

[0024] The above-mentioned side shift mechanism for a sole side shift forming machine can be further configured as follows: one end of the fixed die group corresponding to the side shift cylinder is provided with a side shift drive seat fixedly connected to the fixed die group, the output end of the side shift cylinder is connected to the side shift drive seat, the number of the side shift limit blocks is 2, and they are respectively the first side shift limit block and the second side shift limit block, the first side shift limit block and the second side shift limit block are respectively arranged at the two ends of the travel trajectory of the side shift drive seat, when the side shift drive seat is against the first side shift limit block, the first fixed die frame and the movable die frame are arranged relative to each other, when the side shift drive seat is against the second side shift limit block, the second fixed die frame and the movable die frame are arranged relative to each other.

[0025] By adopting the above technical solution, a first lateral shift limit block and a second lateral shift limit block are set on the transverse shift bracket, wherein the first lateral shift limit block is set in the middle position of the transverse shift bracket, and the second lateral shift limit block is set at the side position of the transverse shift bracket, and the transverse shift drive seat is set between the first lateral shift limit block and the second lateral shift limit block, 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 offsetting each other, the first and second fixed mold frames can be accurately aligned with the movable mold frame respectively.

[0026] The above-mentioned side shift mechanism for a shoe sole side shift forming machine may be further configured as follows: a pressure sensor or a displacement sensor is provided on the side shift cylinder, and the pressure sensor or the displacement sensor is electrically connected to the side shift cylinder.

[0027] When adopting the above technical solution, 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 module and the lateral limit block are against each other, 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 anti-vibration and anti-shock properties. The electrical signal is transmitted to the control system through the above sensor, which facilitates the precise control of the lateral stable switching of the fixed module.

[0038] like Figure 1-Figure 5 As shown, a side shift mechanism for a sole side shift forming machine includes:

[0039] The forming frame 1 is provided with a transverse support 11 and a driving support 12 for support, and a plurality of guide shafts 13 are provided between the transverse support 11 and the driving support 12;

[0040] The movable die set 2 is movably mounted on the guide shaft 13 and can be driven by the mold clamping mechanism to slide along the guide shaft 13 to achieve mold closing and mold opening with the fixed die set 3. A movable die frame 21 is provided on the side of the movable die set 2 facing the fixed die set 3;

[0041] The fixed die set 3 can slide horizontally along the transverse bracket 11. The fixed die set 3 includes a first fixed die frame 31 and a second fixed die frame 32, both of which are identically arranged on the left and right sides and face the movable die frame 21.

[0042] Conveyor belt 4, the conveyor belt 4 is provided below the forming frame 1 corresponding to the movable die set 2, for receiving the formed sole after falling and sending it out of the forming frame 1;

[0043] The fixed die group 3 can slide laterally left and right along the transverse bracket 11, so that the first fixed die frame 31 and the second fixed die frame 32 can be intermittently arranged opposite to the movable die frame 21. When the first fixed die frame 31 is opposite to the movable die frame 21, the second fixed die frame 32 is arranged on the right side of the movable die group 2. At this time, the movable die frame 21 can be clamped with the first fixed die frame 31 through the clamping mechanism; when the second fixed die frame 32 is opposite to the movable die frame 21, the first fixed die frame 31 is arranged on the left side of the movable die group 2. At this time, the movable die frame 21 can be clamped with the second fixed die frame 32 through the clamping mechanism. The left and right sides of the forming frame 2 corresponding to the movable die group 3 are provided with a discharge station A for workers to place inserts here.

[0044] like Figure 1-Figure 5 As shown, the mold clamping mechanism includes a plurality of mold clamping cylinders 121 arranged on the driving bracket 12 corresponding to the movable mold group 2. The output end of the mold clamping cylinder 121 is connected to the movable mold group 2, and the mold clamping cylinder 121 drives the movable mold group 2 along the guide axis to approach or move away from the fixed mold group 3 to complete the mold opening or closing action.

[0045] like Figure 4 、 Figure 5As shown, the fixed die group 3 is slidably connected to the transverse bracket 11 through a slider rail structure. The forming frame 1 is provided with a lateral drive mechanism corresponding to the fixed die group 3 to drive the first fixed die frame 31 and the second fixed die frame 32 on the fixed die group 3 to slide back and forth along the transverse bracket 11. The slider rail structure includes two upper and lower transverse slide rails 111 arranged in the direction of the transverse bracket 11 corresponding to the movable die frame 21 and 8 fixed die sliders 30 arranged on the fixed die group 3 and sliding with the transverse slide rails 111. The fixed die sliders 30 are mounted on the transverse slide rails 111 so that the lateral drive mechanism can drive the fixed die group 3 moves back and forth along the transverse slide rail 11. The lateral drive mechanism includes a transverse oil cylinder 5 provided on the transverse bracket 11. The output end of the transverse oil cylinder 5 is connected to the fixed die group 3. The transverse oil cylinder 5 is arranged in parallel with the transverse slide rail 111. The transverse bracket 11 is provided with a first lateral limit block 112 and a second lateral limit block 113 in the direction of travel of the fixed die group 3. The fixed die group 3 is provided with a transverse drive seat 51 fixedly connected to the fixed die group 3 at one end corresponding to the transverse oil cylinder 5. The output end of the transverse oil cylinder 5 is hinged to the transverse drive seat 51. The first lateral limit block 112 and the second lateral limit block 113 are hinged to each other. The blocks 113 are respectively arranged at both ends of the travel track of the transverse driving seat 51. When the transverse driving seat 51 is against the first lateral limit block 112, the first fixed mold frame 31 and the movable mold frame 21 are arranged relative to each other. When the transverse driving seat 51 is against the second lateral limit block 113, the second fixed mold frame 32 and the movable mold frame 21 are arranged relative to each other. Correspondingly, in order to realize automatic control, a magnetostrictive displacement sensor for monitoring the travel speed of the cylinder is provided on the transverse oil cylinder 5. The magnetostrictive displacement sensor transmits the detected displacement speed signal to the molding machine control system. Specifically, when it is necessary to move from the first When the fixed mold frame 31 switches to the second fixed mold frame 32, the transverse cylinder 5 will push the fixed mold group 3 to the left. At this time, the signal speed monitored by the magnetostrictive displacement sensor is stable. When the fixed mold group 3 and the second lateral shift limit block 113 are limited, it indicates that the second fixed mold frame 32 is already opposite to the movable mold frame 21. At this time, the transverse cylinder 5 cannot push at all, and the displacement signal of the magnetostrictive displacement sensor decreases until it reaches 0. At this time, it is determined that the transverse shift has been completed. The transverse cylinder 5 will automatically stop working, and vice versa for the first lateral shift limit block 112, thereby realizing complete automatic lateral shift control.

[0046] When the side shift mechanism of the present invention is used on the sole forming machine, the sole is currently being formed by the first fixed die frame 31 and the movable die frame 21 being molded together. At this time, the worker can safely and conveniently put in the insert at the unloading station A on the right. When the molding is completed, the sole is directly ejected by the push rod or hooked out of the first fixed die frame 31 or the movable die frame 21, and directly falls onto the conveyor belt 4 below and is transported out of the frame 1. Then the transverse oil cylinder 5 starts working to push the fixed die group 3 to slide along the transverse slide rail 11 until the second side shift limit block 113 is aligned with the transverse limit block 113. The driving seat 51 is against the limit, and the displacement signal of the magnetostrictive displacement sensor drops to 0. At this time, it is determined that the lateral movement has been completed. The lateral movement cylinder 5 will automatically stop working and push the second fixed mold frame 32 with the insert to the position corresponding to the movable mold frame 21. Then the mold closing cylinder 121 drives the movable mold group 2 to close the mold along the guide shaft 13 to the fixed mold group 3, and the insert and the sole are formed into one piece. At this time, the worker places the insert on the first fixed mold frame 31 at the unloading station A on the left, realizing a stable one-work-one-wait, which greatly improves the processing efficiency and safety and convenience.
