AI Technical Summary
In the prior art, when the upper and lower molds are hot-pressed in the rubber shoe sole production device, the displacement of the lower mold and the lifting of the upper mold are inconsistent, which causes mutual obstruction during the molding process and affects the molding effect of the shoe sole.
The upper mold is raised and lowered by a rack and pinion transmission mechanism combined with a bevel gear set to ensure that the upper mold is raised and lowered synchronously with the lower mold. The upper mold is driven to move down by a hydraulic rod, which in turn moves the lower mold and keeps it aligned by a limit block to avoid obstruction. At the same time, a fan is used to accelerate the cooling after molding, and the shoe sole is easily removed by a support plate and a raised column.
The system enables synchronous movement of the upper and lower mold plates, avoiding obstacles during the molding process, improving production efficiency, and enhancing the automation and safety of the device through cooling and convenient removal processes.

[0012] This utility model provides a hot pressing molding device for producing rubber shoe soles, which has the following beneficial effects:
[0013] 1. The hot-pressing molding device for producing rubber shoe soles uses the meshing between racks and gears and bevel gear sets to drive the hydraulic rod and lead screw. The lifting and lowering of the upper template is consistent with the displacement of the lower template. While automatically transferring the lower template, the convex slider inside the worktable connects with the convex limiting block at the bottom of the lower template. After the lower template is aligned with the upper template, the baffle on the worktable limits the lower template to prevent its continuous displacement. Through the deformation of the spring on one side of the convex limiting block, the transmission mechanism can still continuously drive the convex slider and the convex limiting block to move, without hindering the continuous downward movement of the upper template and the hot pressing of the material.
[0014] 2. The hot pressing molding device for producing rubber shoe soles uses a fan installed on the upper template side of the support frame to accelerate the cooling of the molded shoe sole. The storage cavity of the lower template is equipped with a support plate. Under the action of the handle, multiple protruding columns on the support plate can be pushed to push the shoe sole out of the molding groove, making it easy to remove the shoe sole.

The top of the worktable 1 is installed with a baffle 17, the interior of the worktable 1 is provided with a groove 12 on the side away from the convex groove 7, the interior of the groove 12 is rotatably connected with a first bevel gear 13 and a second bevel gear 14, the first bevel gear 13 and the second bevel gear 14 mesh with each other, the first bevel gear 13 is connected to the lead screw 11, the interior of the groove 12 and located on the side of the second bevel gear 14 is rotatably connected with a first gear 15, the second bevel gear 14 and the first gear 15 mesh with the first gear 14. A wheel 15 is connected. A limiting hole 29 is provided inside the workbench 1 on one side of the groove 12. A rack 16 is installed on one side of the upper template 4, passing through the limiting hole 29. The rack 16 meshes with the first gear 15. Through the meshing of the first bevel gear 13 and the second bevel gear 14, the first gear 15 is driven by the lead screw 11. As the upper template 4 moves downward, the rack 16 drives the first gear 15 and the lead screw 11 to rotate. The downward movement of the upper template 4 can be consistent with the displacement of the lower template 9, replacing manual transfer of the lower template 9. A convex limiting groove 18 is provided at the bottom of the lower template 9. A convex limiting block 19 is slidably connected inside the convex limiting groove 18. The convex limiting block 19 is connected to the convex slider 8. A telescopic spring 20 is installed, one end of which is connected to a convex limiting block 19.

Similarly, the convex slider 8 is connected to the convex limiting block 19 in the convex limiting groove 18 at the bottom of the lower mold plate 9. A telescopic spring 20 is provided on one side of the convex limiting block 19, causing the lower mold plate 9 to move accordingly via the telescopic spring 20. When plate 9 is aligned with upper template 4, baffle 17 on workbench 1 abuts against lower template 9, stopping its movement. During the descent of upper template 4, transmission mechanism causes convex slider 8 and convex limiting block 19 to continuously move. The telescopic spring 20 deforms after being squeezed by convex limiting block 19, providing space for convex slider 8 and convex limiting block 19 to continuously move, while the position of lower template 9 remains unchanged, causing bottom pressure plate 5 of upper template 4 to be inserted into forming groove 10 of lower template 9, applying pressure, and cooperating with heating component 6 to hot press the material. After completion, reverse the operation, upper template 4 and lower template 9 are reset, and fan 22 runs to dissipate heat from lower template 9. As needed, the support plate 25 in the storage cavity 23 of lower template 9 can be pushed upward by handle 27, so that multiple protruding columns 26 on support plate 25 pass through multiple inlet and outlet holes 24 into forming groove 10, pushing out the formed insole.
