The surface of the bottom template is provided with a positioning mold limiting plate. The top of the bottom template is also provided with a parallel top template, which is fixed to the top of the frame by a limiting frame on the surface.

[0007] The bottom template includes a plate body with a groove in the middle. The plate body is nested with the bottom template through fitting holes on both sides. A sliding plate is nested inside the groove, and the sliding plate slides in conjunction with the groove. The surface of the plate body is also provided with fixing holes that cooperate with the mold. The sliding plate is nested in conjunction with the limiting protrusions in the groove of the plate body. The sliding plate is provided with a first moving plate and a second moving plate. The first moving plate and the second moving plate slide in conjunction with the groove through pulleys on both sides. A control handle is provided inside the second moving plate. The control handle is connected to a locking part installed inside the first moving plate. When the control handle swings left and right, the locking part moves synchronously.

[0008] Preferably, the engaging part includes a base plate and a limiting block installed on the top of the base plate, and a sliding arm is fixed to the side of the base plate, the sliding arm being connected to the control handle.

[0009] Preferably, the inner groove of the supporting frame of the first moving plate is provided with a sliding rail, the sliding rail is movably connected with the bottom plate at the bottom of the limiting block, and the surface of the supporting frame is further provided with an inner groove, the bottom plate is nested and flush with the surface of the inner groove.

[0010] Preferably, the control handle comprises a handle, one side of the handle is provided with a positioning seat, the positioning seat is installed in the middle of the second rotating shaft, a control gear is arranged at the rotating shaft connected with the positioning seat of the handle, the control gear is fixedly connected with the handle, the handle swings to drive the control gear to rotate, an adjusting sliding cavity is arranged adjacent to the control gear, the adjusting sliding cavity is movably connected with the second rotating shaft through the sliding shafts at the two sides, and a synchronous arm is arranged at the main shaft of the control gear.

[0011] Preferably, two cylindrical shaft bodies are arranged at the connection between the synchronous arm and the groove hole at the top of the adjusting sliding cavity, and the cylindrical shaft bodies are slidably connected with the groove hole of the adjusting sliding cavity.

[0012] Preferably, the handle extends into the groove of the hand groove.

[0013] Preferably, the second rotating shaft is movably connected with the positioning seat, and the middle of the second rotating shaft is provided with a protrusion for limiting the left and right movement of the positioning seat.

[0014] Preferably, the sliding groove is provided with two depths, and when the first moving plate is located in the area with a larger depth, the plane of the supporting frame is lower than the plane of the plate body.

[0015] Preferably, the adjusting sliding cavity is a cylindrical structure, the top of the cylindrical structure is provided with a plane, the edge of the plane is provided with a rack, and the control gear is adhesively connected with the rack for transmission.

[0016] Preferably, the middle of the supporting frame is provided with two through grooves, and one sliding rail is arranged in each groove.

[0017] The environment-friendly rubber foaming forming machine has the following effects:

[0018] It can protect the surface of the equipment and reduce wear: By setting the limit plate and slide plate structure, the mold does not need to directly contact the bottom template when changing the mold, avoiding scratches on the bottom template surface caused by manual pushing and pulling of the mold, reducing equipment maintenance costs, and extending the service life of the bottom template. The sliding of the slide plate and the slide groove replaces the direct friction between the mold and the bottom template, reducing the generation of iron filings. At the same time, it avoids the problem of uneven mold placement caused by iron filings, ensuring the precision of the subsequent injection molded products.

[0019] Furthermore, it achieves precise mold positioning and improves replacement efficiency: the slide plate achieves initial positioning by fitting with the plate body through the limiting protrusion, and performs coarse positioning by nesting with the limiting block of the locking part and the bottom of the mold. Then, the control handle drives the control gear to drive the slide arm to make fine adjustments left and right, so that the bolt holes can be quickly and accurately aligned. This solves the problems of low efficiency and poor accuracy of traditional manual positioning, and improves the convenience and accuracy of mold replacement.

[0020] It can also adapt to narrow spaces and enhance operational flexibility: The skateboard adopts a two-section structure of a second moving plate and a first moving plate. It can be bent and folded through the first pivot on one side of the support frame, which effectively reduces the volume during the lateral movement and can be operated in narrow spaces. This improves the adaptability of the equipment in different production scenarios. During the folding process, the adjustment cavity is connected to the main shaft of the control gear through the synchronous arm. When the handle drives the second plate to rotate, it can drive the adjustment cavity to rotate synchronously, avoiding misalignment. This structure can achieve folding and storage without affecting the stability of the adjustment operation, making the overall use more convenient and efficient. Attached Figure Description

[0040] The existing production process needs to replace the sole mold, and the traditional way is to directly place the mold on the surface of the bottom template 11, and push and pull manually until it is positioned in the limiting hole. In the process of sliding, scratches are caused on the surface of the bottom template 11, and iron filings are easy to cause unevenness of the mold. In order to solve the above problems, the technical scheme is as follows:

[0041] Please refer to Figures 1 to 7 The present application provides a kind of environmental protection rubber foaming forming machine technical scheme: its structure includes: frame 2, the frame 2 inside installation is clamped mould's forming part 1, the front end of the forming part 1 is equipped with the operation table 6 of placing, still be installed with the control panel 5 of controlling forming part 1 movement in the side of frame 2, the top of the frame 2 is also installed with protective top plate 4, the top of the frame 2 is also provided with exhaust hole 3, forming part 1 includes bottom template 11, bottom template 11 is installed at the top of pusher 15, pusher 15 is arranged in the inside of frame 2, the surface of the bottom template 11 is provided with limiting plate 12 of positioning mould, the top of bottom template 11 is also provided with the top template 13 of parallel arrangement, top template 13 is fixed on the top of frame 2 by the limiting frame 14 on surface;

[0042] Bottom template 11 includes plate body 121, the middle part of the plate body 121 is equipped with sliding groove 122, the plate body 121 is nested with bottom template 11 by the embedding hole 124 on both sides, the sliding groove 122 is nested with sliding plate 123, the sliding plate 123 is slidably connected with the sliding groove 122, the surface of the plate body 121 is also provided with fixed hole 125 matched with mould, the sliding plate 123 is nested with limiting protrusion 126 in the sliding groove of plate body 121, the sliding plate 123 is provided with first moving plate 231 and second moving plate 233, the first moving plate 231 and the second moving plate 233 are slidably connected with the sliding groove 122 by the pulley 232 on both sides, the second moving plate 233 is provided with control handle 235 inside, the control handle 235 is connected with the clamping part 234 installed in the first moving plate 231, and the control handle 235 swings the clamping part 234 synchronous movement.

[0043] The main structure of the device includes a forming part 1, which is installed inside the frame 2. During injection molding, an odor is generated, so an exhaust hole 3 is provided at the top of the frame 2 to discharge the odor. A protective top plate 4 is provided at the top of the frame 2 for easy operation of the operation table 6. The protective top plate 4 is provided with a light source inside for lighting. The control panel 5 is installed on the side of the frame 2 to control multiple stations.

[0044] The structure of the forming part 1 includes a bottom template 11 for installing a limiting plate 12. The limiting plate 12 is used to fix the mold. The bottom pusher 15 uses a hydraulic push rod to push the lower mold fixed by the limiting plate 12 upwards to press the upper mold of the top template 13. The top template 13 is fixed to the top of the frame 2 by the limiting frame 14. During the pressing process, rubber foaming is injected, and then static pressure forming is performed. The limiting frame 14 is provided with a heat preservation rolling door 16 on both sides to facilitate temperature control, improve heat preservation effect, and reduce environmental impact.

[0045] During production, the production mold of the sole needs to be replaced. In the traditional way, the mold is directly placed on the surface of the bottom template 11 and pushed and pulled manually until it is positioned in the limiting hole. During the sliding process, scratches are caused on the surface of the bottom template 11, and iron filings are easily generated to cause unevenness of the mold.

[0046] To solve the above problems, the limiting plate 12 is used. The plate body 121 of the limiting plate 12 is fixed to the bottom template 11 through the embedding holes 124 on both sides. The middle part of the plate body 121 is provided with a sliding plate 123 that can slide to push the mold into the sliding groove 122 inside the plate body 121. When the sliding plate 123 reaches the limiting position, it is embedded with the limiting protrusion 126 in the middle part of the plate body 121. When the sliding plate 123 brings the mold to the fixing hole 125, it can be fixed.

[0047] The sliding plate 123 is provided with two sections, the second moving plate 233 and the first moving plate 231 are combined, and the pulleys 232 on both sides are matched with the sliding groove 122. When the first moving plate 231 slides into the sliding groove 122, it is embedded and sinks, so that the mold is attached to the surface of the plate body 121. The pulleys 232 only control the forward feeding of the mold by the second moving plate 233 and the first moving plate 231, and cannot adjust left and right. To solve this problem, the device is provided with a control handle 235 for adjustment. The control handle 235 controls the movement of the clamping part 234. The clamping part 234 is installed in the support frame 311 of the first moving plate 231 and slides with the sliding rail 314. The inner groove 315 on the surface of the support frame 311 is used for support.

[0048] The first rotating shaft 312 is arranged on one side of the supporting frame 311, and cooperates with the second moving plate 233, so that the sliding plate 123 can be folded to reduce the volume when sliding to the outside. The movable hole 313 is arranged in the middle of the supporting frame 311 and is nested with the sliding arm 343 of the clamping part 234. The limiting block 341 at the top of the clamping part 234 is nested with the bottom of the mold for rough positioning. The bottom plate 342 at the bottom of the limiting block 341 is connected with the control handle 235 through the sliding arm 343. The control handle 235 can be adjusted when it swings, so as to avoid damage caused by sliding on the surface of the bottom plate.

[0049] The adjustment mode is as follows. The control handle 235 is installed in the middle groove 333 of the second plate body 331 and is clamped with the hand groove 332 on the surface of the second plate body 331. The hand groove 332 is limited and facilitates pulling the mold during operation. The front end of the second plate body 331 is provided with a second rotating shaft 334. The second rotating shaft 334 cooperates with the second plate body 331. The second rotating shaft 334 is connected with the positioning seat 352. The positioning seat 352 is limited in the middle of the second rotating shaft 334 and cannot deviate left and right. The top of the handle 351 is provided with a control gear 353. When the handle 351 rotates, the control gear 353 is driven to move. The adjustment sliding cavity 355 nested on the surface of the second rotating shaft 334 is driven to move. The adjustment sliding cavity 355 is slidably connected with the second rotating shaft 334 through the slide shaft 356 on both sides. The second rotating shaft 334 is nested in the movable shaft of the sliding arm 343. When the adjustment sliding cavity 355 is driven to move left and right by the control gear 353, the limiting block 341 slides left and right under the support of the slide rail 314, so that the bolt hole can be quickly positioned.

[0050] Moreover, as mentioned above, the second moving plate 233 and the first moving plate 231 are double-segment structures, which are mainly used to reduce the volume during horizontal movement and can be operated in a narrow space. However, during folding, the device is rotated through the second rotating shaft 334. The adjustment sliding cavity 355 is connected with the main shaft of the control gear 353 through the synchronous arm 354. When the handle 351 is driven by the second plate body 331, the adjustment sliding cavity 355 can be rotated by a certain angle. The teeth are avoided to be misaligned. The structure can be folded and will not affect the operation. It is more convenient to use.

[0051] The way of replacing the mold of the device is as follows:

[0052] S1: Place the mold on the top of the sliding plate 123 for clamping and limiting, and then push the second moving plate 233 and the first moving plate 231.

[0053] S2: When the mold is temporarily positioned in the pre-positioning hole in the middle of the fixed hole 125, the mold is roughly aligned with the fixed hole 125.

[0054] S3 operates the handle 351, rotates the handle 351 to drive the control gear 353, at this time the control gear 353 drives the sliding shaft 356 to move, and the sliding arm 343 is pressed and slid to finely adjust left and right.

[0055] S4 pushes the whole to the innermost part of the sliding groove 122, nests with the limiting protrusion 126, and can be fixed after the bolt is matched with the mold.

[0056] The improved device:

[0057] The device surface can be protected and the loss can be reduced: by setting the limiting plate 12 and the sliding plate 123 structure, the mold does not need to be directly contacted with the bottom template 11 during replacement, the surface scratches of the bottom template 11 caused by manual pushing and pulling of the mold are avoided, the equipment maintenance cost is reduced, and the service life of the bottom template is prolonged.

[0058] The cooperation and sliding of the sliding plate 123 and the sliding groove 122 replace the direct friction of the mold and the bottom template, reduce the generation of iron filings, avoid the problem of uneven placement of the mold caused by the iron filings, and guarantee the product precision of subsequent injection molding.

[0059] And accurate positioning of the mold is realized, and the replacement efficiency is improved: the sliding plate 123 is embedded with the plate body 121 to realize preliminary positioning, the limiting block 341 of the clamping part 234 is nested with the bottom of the mold to realize coarse positioning, and then the control handle 235 drives the control gear 353 to drive the sliding arm 343 to finely adjust left and right, so that the bolt hole is quickly and accurately positioned, the problems of low efficiency and poor precision of traditional manual positioning are solved, and the convenience and accuracy of mold replacement are improved.

[0060] It can also adapt to narrow space and enhance operation flexibility: the sliding plate 123 adopts a double-section structure of the second moving plate 233 and the first moving plate 231, and can be bent and folded through the first rotating shaft 312 on one side of the supporting frame 311, effectively reducing the volume during horizontal movement, and can be operated in a narrow space, improving the adaptability of the device in different production scenes. During folding, the adjusting sliding cavity 355 is connected with the main shaft of the control gear 353 through the synchronous arm 354, and when the handle 351 drives the second plate body 331 to rotate, it can drive the adjusting sliding cavity 355 to rotate synchronously, avoiding the phenomenon of misalignment, so that the structure can realize folding and storage without affecting the stability of the adjusting operation, and the whole use is more convenient and efficient.
