Description

Technical Field

[0001] The utility model relates to the technical field of shoe upper processing equipment, in particular to a three-dimensional molded shoe upper molding device. Background Art

[0002] As people's living standards gradually improve, the pursuit of shoe beauty is getting higher and higher. Not only do they require durability, but they also require three-dimensional beauty. Traditional three-dimensional uppers are formed by foam or other fillers to achieve a three-dimensional effect. Although such uppers can achieve a basic three-dimensional molding effect, the three-dimensional effect will gradually weaken, and the foam is easily oxidized and yellowed, and it is easy to rot when exposed to water. Using the method of filling EVA plastic and applying the pre-fixed alignment method can form a three-dimensional molding effect of different heights, sizes, shapes, and colors, with precise alignment, good three-dimensional effect, and not easy to deform and rot.

[0003] At present, in the process of shoe upper manufacturing, secondary melting is generally a secondary processing technology carried out on two-dimensional flat materials (such as leather, mesh, flying weave, etc.). The flat flying weave shoe upper is subjected to secondary melting and coating through a molding device, and then spliced ​​into a three-dimensional shoe upper on a sewing machine, and then put into the last for final shaping.

[0004] Based on the above, the inventors found that: when molding the upper, the upper is usually placed in a mold, and then the mold is moved to a molding device, and heated and molded to avoid forming a three-dimensional pattern. However, most existing molding devices are not convenient for limiting the position of the mold. Since the material will expand to the level before cold pressing after heating, the material and the mold are easily displaced, which causes the product to have a double image phenomenon and the three-dimensional sense of concave and convex is not obvious, affecting the quality of the product. Therefore, in view of this, the existing structure is studied and improved, and a three-dimensional molded upper molding device is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In view of the above problems, the present application provides a three-dimensional molded upper molding device, which is used to solve the technical problems that the mold and material on the existing molding device are shifted, resulting in double shadow phenomenon and unclear concave and convex three-dimensional effect after product molding.

[0006] To achieve the above objectives, in a first aspect, the present application provides a three-dimensional molded upper molding device, comprising:

[0007] Workbench; and

[0008] Two mounting frames, the two mounting frames are respectively fixed at the two ends of the top of the workbench, the heating mechanism and the molding mechanism are respectively installed on the sides of the two mounting frames close to each other, two guide rails are arranged between the two mounting frames, a lower mold is slidably connected between the two guide rails, an upper mold is arranged on the top of the lower mold, two symmetrically arranged clamps are fixedly connected on both sides of the lower mold, and corresponding clamping positions on both sides of the upper mold are fixedly connected with clamping blocks, and the clamping members are clamped with corresponding clamping blocks;

[0009] The clamping member includes a support plate fixed to the outer side of the lower mold, the top of the support plate is fixedly connected to a sleeve, the inside of the sleeve is slidably connected to a sliding rod, the top of the sliding rod extends to the top of the sleeve and is rotatably connected to the clamping plate through a bearing, a return spring is arranged inside the sleeve, and the return spring is located at the bottom of the sliding rod.

[0010] As an implementation mode of the utility model, the reset spring is in a stretched state, and both ends are fixedly connected to the inner bottom of the sleeve and the bottom end of the sliding rod respectively.

[0011] As an implementation mode of the utility model, an open groove is provided on one side of the clamping block, and one end of the corresponding clamping plate is clamped in the open groove.

[0012] As an implementation mode of the utility model, two symmetrically arranged limit grooves are provided on both sides of the lower mold, and a limit rod is fixedly connected to the position of the limit groove at the bottom of the upper mold, and the limit rod is clamped in the corresponding limit groove.

[0013] As an implementation mode of the utility model, the heating mechanism comprises a first lifting cylinder, the first lifting cylinder is mounted on one of the mounting frames, and the output end of the first lifting cylinder is fixedly connected to a heating plate.

[0014] As an implementation mode of the utility model, the molding mechanism includes a second lifting cylinder, the second lifting cylinder is installed on another mounting frame, and the output end of the second lifting cylinder is fixedly connected to the molding plate.

[0015] As an implementation mode of the utility model, a positioning cylinder is installed on the top of one end of the workbench.

[0016] As an implementation mode of the utility model, the output end of the positioning cylinder is fixedly connected to a side of the lower mold close to the heating plate.

[0017] Different from the prior art, the technical solution of the present application uses a limiting rod and a limiting groove to limit the upper mold and the lower mold, and clamp the upper material between the two, thereby effectively avoiding the displacement between the upper mold and the lower mold, so that the upper material is kept in the right position in the mold, avoiding the double shadow phenomenon after the upper material is processed, making it have a distinct concave and convex three-dimensional sense, and improving the quality of its products. By setting a return spring in a stretched state, and using the sliding rod, the card plate and the card block, the card plate is inserted into the open groove on the card block, so that the upper mold and the lower mold can be connected and fixed, and the elastic force generated by the deformation of the return spring is used to press the upper material between the two, thereby improving its stability during die pressing.

When in use, the positioning cylinder 13 can be set and the guide rail 5 cooperates to drive the position of the lower mold 6 to move.

[0057] When in use: place the upper material on the lower mold 6, then press the upper mold 7 on the top of the upper material, then lift the sliding rod 803 in turn, and insert the clamping plate 804 into the open groove 10 on the corresponding clamping block 9, so that the lower mold 6 is connected to the upper mold 7, and the upper material is pressed and limited. At the same time, the upper mold 7 and the lower mold 6 can be limited by the use of the limiting rod 12 and the limiting groove 11, thereby effectively avoiding the offset between the upper mold 7 and the lower mold 6, so that the upper material remains in the correct position in the mold, avoiding the double shadow phenomenon after the upper material is processed, making it have a distinct concave and convex three-dimensional sense, and improving the quality of the product.
