Description

Technical Field

[0001] This utility model belongs to the field of rubber shoe sole production technology, and in particular relates to a rubber shoe sole shaping device. Background Technology

[0002] A rubber sole shaping device is a device that uses physical pressure, heating vulcanization or other processes to shape and solidify raw materials (such as natural rubber, synthetic rubber or compound rubber) according to a preset mold.

[0003] Traditional rubber sole molding equipment typically uses rubber injection molding machines for processing. Through the cooperation of upper and lower molds, and by heating, the rubber material is shaped into a sole. However, during the molding process, workers need to wait for the molding to complete before pulling out the mold, cooling and demolding the sole, and then putting the rubber material back into the mold for the next molding. This method leads to a significant waste of time, as the waiting time for molding and cooling is difficult to utilize, thus reducing the production efficiency of soles. Utility Model Content

[0004] The purpose of this invention is to provide a rubber sole molding device. By setting a switching mechanism, specifically two lower molds on a moving plate, one for molding and the other for adding rubber material for pretreatment, the device allows for cooling and demolding of the molded sole during the molding process. The two lower molds only need to be switched by pushing the moving plate. This method enables molding and demolding to occur simultaneously, resulting in more continuous sole production and significantly increased output. It solves the problem of traditional rubber sole molding devices where workers need to wait for molding to complete before pulling out the mold, cooling and demolding the sole, and then adding rubber material for the next molding cycle, which leads to significant time waste.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rubber shoe sole shaping device, including a base, a fixed platform fixedly connected to the top of the base, and a rubber injection molding machine mounted on the top of the base via a column. It also includes:

[0007] The shifting mechanism is located on the top of the fixed platform. The shifting mechanism includes a movable plate that is slidably connected to the top of the fixed platform. Two lower molds are positioned and installed on the movable plate. The rubber injection molding machine has an upper mold installed on the output end of a hydraulic cylinder. The two lower molds are arranged longitudinally on the movable plate.

[0008] The upper mold is adapted to the lower mold, and the movable plate is used to sequentially swap the positions of the two lower molds.

[0009] Furthermore, the top left and right sides of the fixed platform are fixedly connected to limit rails, and two sliding grooves are opened on the top of the fixed platform. The moving plate is slidably connected to the inner side of the limit rails. When the moving plate moves, it will slide inside the limit rails, making the moving plate more stable when moving.

[0010] The limiting rail is used to limit the movement of the moving plate.

[0011] Furthermore, handles are fixedly connected to both the front and back of the movable plate, and several positioning blocks are fixedly connected to the top of the movable plate, with four positioning blocks arranged in groups. Two sliders are fixedly connected to the bottom of the movable plate, and spherical positioning grooves are opened at both ends of the bottom of the movable plate. The lower mold is positioned and inserted into the positioning blocks through the positioning holes at the bottom, thereby positioning the lower mold on the movable plate. Then, bolts are inserted into the convex plate and threadedly connected to the movable plate to lock and fix the lower mold, thus quickly completing the installation.

[0012] The bottom of the movable plate is slidably connected to the inside of the slide groove by a slider, and the slider and the slide groove cooperate to limit the movement of the movable plate.

[0013] Furthermore, protrusions are fixedly connected to the left and right sides of the lower mold, and protruding plates are fixedly connected to the front and back of the lower mold. Positioning holes are provided at the four corners of the bottom of the lower mold, and the bottom of the lower mold is positioned and inserted into the positioning block through the positioning holes. The bolts on the protruding plate are removed to release the fixation of the lower mold. Then, the lower mold is lifted upward by pulling the protrusions to facilitate the disassembly of the lower mold.

[0014] The positioning block is used to position and install the lower mold, and the convex plate is used to insert bolts and connect with the moving plate by threads.

[0015] Furthermore, the repositioning mechanism also includes positioning components, of which two sets are provided, respectively located on the front and back of the base. The positioning components are used to position and limit the moved plate after it has been moved.

[0016] Furthermore, the positioning component includes a fixed column fixedly connected inside the base, a positioning block slidably connected inside the fixed column, a stabilizing rod slidably connected to the bottom of the positioning block, a spring sleeved on the outside of the stabilizing rod, and the bottom of the stabilizing rod fixedly connected to the bottom of the inner wall of the fixed column; when the two positioning blocks are switched, only one positioning block enters the spherical positioning groove, while the other positioning block is misaligned with the other spherical positioning groove;

[0017] The top of the positioning block slides through the fixed column and the fixed platform and extends to the bottom of the moving plate. The top of the fixed column is spherical, and the inner wall of the spherical positioning groove is spherical.

[0018] Furthermore, the spherical surface at the top of the positioning block is adapted to the spherical positioning groove, and the bottom of the positioning block is provided with a convex plate. The convex plate at the bottom of the positioning block is used to limit the positioning block. The top of the spring is fixedly connected to the bottom of the positioning block, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the fixing column. The convex plate is used to limit the movement distance of the positioning block and facilitates pushing and squeezing the spring.

This method can make shaping and demolding simultaneous, making shoe sole production more continuous and greatly increasing output.

[0021] 2. This utility model, by setting a positioning component, specifically, when the moving plate is being repositioned, when one of the spherical positioning grooves moves to the position of one of the positioning blocks, the positioning block will enter the spherical positioning groove by the elastic force of the spring, thereby positioning the moving plate. At this time, the pushing of the moving plate can be stopped, and the upper mold and lower mold can be positioned, which facilitates subsequent shaping and prevents the moving plate from shifting.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] Please see Figures 1-6 As shown, this utility model is a rubber shoe sole shaping device, including a base 1, a fixed platform 11 fixedly connected to the top of the base 1, and a rubber injection molding machine 12 mounted on the top of the base 1 via a column. It also includes:

[0034] The shifting mechanism 2 is located on the top of the fixed platform 11. The shifting mechanism 2 includes a movable plate 21 slidably connected to the top of the fixed platform 11. Two lower molds 22 are positioned and installed on the movable plate 21. The rubber injection molding machine 12 has an upper mold installed on the output end of a hydraulic cylinder. The two lower molds 22 are arranged longitudinally on the movable plate 21. One of the two lower molds 22 on the movable plate 21 is used for shaping, and the other is used for adding rubber material for pretreatment. During the shaping process, the shaped shoe sole can be cooled and demolded. The two lower molds 22 only need to push the movable plate 21 to shift positions. This method can make shaping and demolding simultaneous, making the shoe sole production more continuous and greatly increasing the output.

[0035] The upper mold and the lower mold 22 are adapted to each other, and the movable plate 21 is used to change the position of the two lower molds 22 back and forth in sequence.

[0036] The top left and right sides of the fixed platform 11 are fixedly connected to the limiting rails 111. The top of the fixed platform 11 has two sliding grooves 112, and the moving plate 21 is slidably connected to the inner side of the limiting rails 111.

[0037] The limiting rail 111 is used to limit the movement of the moving plate 21.

[0038] The movable plate 21 has handles 211 fixedly connected to both the front and back sides. Several positioning blocks 212 are fixedly connected to the top of the movable plate 21, and the positioning blocks 212 are set in groups of four. Two sliders 213 are fixedly connected to the bottom of the movable plate 21. Spherical positioning grooves 214 are opened at both ends of the bottom of the movable plate 21.

[0039] The bottom of the movable plate 21 is slidably connected to the inside of the slide groove 112 via a slider 213. The slider 213 and the slide groove 112 cooperate to limit the movement of the movable plate 21.

[0040] The lower mold 22 has protrusions 221 fixedly connected to the left and right sides, and protrusions 222 fixedly connected to the front and back sides. The lower mold 22 has positioning holes 223 at the four corners of the bottom. The bottom of the lower mold 22 is positioned and inserted into the positioning block 212 through the positioning holes 223.

[0041] The positioning block 212 is used to position and install the lower mold 22, and the protruding plate 222 is used to insert bolts and thread them to the moving plate 21.

[0042] The shifting mechanism 2 also includes a positioning component 23. There are two sets of positioning components 23, which are respectively set on the front and back of the base 1. The positioning component 23 is used to position and limit the moved plate 21 after it has been moved.

[0043] The positioning component 23 includes a fixed column 231 fixedly connected inside the base 1. A positioning block 232 is slidably connected inside the fixed column 231. A stabilizing rod 233 is slidably connected to the bottom of the positioning block 232. A spring 234 is sleeved on the outside of the stabilizing rod 233. The bottom of the stabilizing rod 233 is fixedly connected to the bottom of the inner wall of the fixed column 231. When the moving plate 21 is repositioned, when one of the spherical positioning grooves 214 moves to the position of one of the positioning blocks 232, the positioning block 232 will enter the spherical positioning groove 214 by the elastic force of the spring 234, thereby positioning the moving plate 21. At this time, the pushing of the moving plate 21 can be stopped, and the upper mold and the lower mold 22 can be positioned, which facilitates subsequent shaping and prevents the moving plate 21 from shifting.

[0044] The top of the positioning block 232 slides through the fixed post 231 and the fixed platform 11 and extends to the bottom of the moving plate 21. The top of the fixed post 231 is spherical, and the inner wall of the spherical positioning groove 214 is spherical.

[0045] The spherical surface at the top of the positioning block 232 is adapted to the spherical positioning groove 214.

The top of the spring 234 is fixedly connected to the bottom of the positioning block 232, and the bottom of the spring 234 is fixedly connected to the bottom of the inner wall of the fixing post 231.

[0046] One specific application of this embodiment is:

[0047] In use, the rubber material is placed into the slot on the lower mold 22. Then, the rubber injection molding machine 12 is started, causing the upper mold to move downwards to engage with the lower mold 22, shaping the rubber material into the shape of a shoe sole. During this process, the operator can place the rubber material into another lower mold 22 for pre-processing for the next shaping. After shaping is complete, the upper mold moves upwards to reset. Then, the operator pushes the handle 211 to move the moving plate 21, switching the positions of the two lower molds 22 on the moving plate 21. During movement, the slider 213 will slide within the groove 112 on the fixed platform 11, and the moving plate 21 will slide inside the limit rail 111, making the movement of the moving plate 21 more stable. Simultaneously, the movement of the moving plate 21 will push the positioning block 232, causing the positioning block 232 to slide on the stabilizing rod 233 and compress the spring 234, allowing the moving plate 21 to move smoothly. When another spherical positioning groove 214 on the moving plate 21 moves to the position of another positioning block 232, the positioning block 232 will... The spring force of spring 234 enters the spherical positioning groove 214, thereby positioning the moving plate 21. At this point, pushing the moving plate 21 can be stopped, and the rubber injection molding machine 12 can then resume the molding process. The sole molded by one of the lower molds 22 can then be cooled, removed by the operator, and rubber material placed inside. This method allows molding and demolding to occur simultaneously, making sole production more continuous and significantly increasing output. This process can be repeated to sequentially switch the positions of the two lower molds 22 for different processes. When more... When replacing mold 22, remove the bolts on the protruding plate 222 to release the fixation of the lower mold 22. Then, lift the lower mold 22 upward by pulling the protrusion 221. The lower mold 22 will then be disengaged from the positioning block 212 for quick disassembly. Then, insert the new lower mold 22 into the positioning block 212 through the positioning hole 223 at the bottom, thereby positioning the lower mold 22 on the moving plate 21. Then, insert bolts into the protruding plate 222 and thread them into the moving plate 21 to lock and fix the lower mold 22, thus completing the replacement quickly.
