SUMMARY

[0004] The utility model relates to a shoe heel forming die that solves the technical problems of the prior art.

[0005] To achieve the above object, the utility model provides the following technical scheme, a kind of shoe heel forming die, including mould core, upper mould core support, lower mould core support and ejection mechanism, characterized in that: the ejection mechanism includes the mobile guide rail being set at the both sides of upper mould core support, the mobile guide rail extends to lower mould core support, the mould core includes mould core plate and forming block, the same two sides of mobile guide rail are equipped with installation cavity, and the installation cavity is equipped with the material pushing block that can move axially, the material pushing block axially moving can push the product on forming block, the mobile guide rail is connected with forming block by linkage structure and is prompted to move to drive the material pushing block axially moving.

[0006] The extension of the mobile guide rail ensures the accurate guidance of the material pushing block during axial movement, thereby effectively avoiding the deformation or damage of the product during demolding. The linkage structure enables the movement of the mobile guide rail to be directly converted into the axial thrust of the material pushing block. By arranging the mobile guide rail linkage material pushing block on both sides of the upper mold core frame, the problems of the existing technology, such as the need to simultaneously process a partition plate for the plunger to abut in the mold, and the concave marks left in the produced heel by the plunger, are avoided.

When the upper mold core frame moves, the abutting plate in the mobile guide rail abuts with the clamping block to drive the material pushing block to move axially.

[0008] The mobile guide rail center mobile slot and the clamping block on the material pushing block are accurately matched to effectively connect the upper mold core frame and the material pushing block. When the upper mold core frame moves, the abutting plate in the mobile guide rail pushes the clamping block, thereby driving the material pushing block to move axially, ensuring that the product is smoothly and completely demolded from the forming block.

[0009] The shoe heel forming mold can be further provided with a mobile guide rail center axially arranged mobile slot, a clamping block arranged on one side of the material pushing block in the mobile slot, an abutting plate arranged in the mobile slot and abutting with the clamping block, and the clamping block arranged in the mobile slot and abutting with the abutting plate. When the upper mold core frame moves, the abutting plate in the mobile guide rail abuts with the clamping block to drive the material pushing block to move axially.

[0010] The stable sliding of the sliding block in the sliding slot effectively prevents the material pushing block from deviating or shaking during axial movement. The abutting of the limiting slot between the limiting plate and the pushing part gives the material pushing block a lower limit, improving the reliability and efficiency of demolding.

[0011] The shoe heel forming mold can be further provided with a pushing part designed as a slope from low to high with the forming block direction as the starting point.

[0012] The pushing part in the mold is designed as a slope from low to high with the forming block direction as the starting point, so that the product can be more smoothly demolded, reducing the surface scratches or deformation of the product caused by too steep demolding angle or too large resistance. The arrangement of the slope also helps to evenly distribute the demolding force, ensuring that the stress on the product during demolding is minimized, thereby protecting the integrity and quality of the product.

[0013] The shoe heel forming die can be further provided with a moving shaft arranged on the two sides of the upper die core frame, the moving guide rail is limitingly installed on the two sides of the upper die core frame through the moving shaft and is axially moved along the moving groove through the moving shaft penetrating the moving groove.

[0014] By arranging the moving shaft on the two sides of the upper die core frame and limitingly installing the moving guide rail thereon, the accurate guidance and stable movement of the moving guide rail are realized, and when the moving shaft is axially moved along the moving groove, it pushes the moving guide rail to move synchronously, thereby ensuring the accurate alignment between the material pushing block and the forming block.

[0015] The upper die core frame is provided with a moving guide rail linkage pushing block arranged on the two sides of the upper die core frame, and the moving guide rail linkage pushing block pushes the finished product on the die core out, thereby avoiding the problems in the prior art that the ejector pin forming die is ejected, a partition plate for abutting against the ejector pin needs to be simultaneously machined in the die, and a concave mark caused by the ejection of the ejector pin is left in the produced shoe heel.
