[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] refer to Figures 1 to 4 A clogs forming mold, comprising an outer mold 1 and a mold core 2, wherein the mold core 2 is located in the outer mold 1, and the outer mold 1 and the mold core 2 form a cavity 3 for forming clogs, and the mold core 2 is provided with a plurality of convex block groups 21, and the plurality of convex block groups 21 are all located in the cavity 3, and the plurality of convex block groups 21 are all in contact with the outer mold 1;

[0020] The outer mold 1 is provided with a plurality of first protrusions 111 corresponding to the positions of the protrusion groups 21 , and a gap is provided between the ends of the first protrusions 111 and the surface of the mold core 2 , and each of the protrusion groups 21 and the corresponding first protrusions 111 form a shape forming area.

[0021] Under this design, the molding material is injected into the cavity 3 between the outer mold 1 and the core mold 2. When the material flows to the bump group 21, the multiple bump groups 21 interfere with the material flow in the cavity 3 so that the material cannot cover the area of ​​the bump group 21. Since there is a gap between the first protrusion 111 on the outer mold 1 and the surface of the core mold 2, the material can flow normally. After the injection molding is completed, the multiple bump groups 21 can form a plurality of holes correspondingly, and the multiple first protrusions 111 can form a plurality of recesses correspondingly. The holes and recesses cooperate to make the upper of the clogs present different shapes, which will reduce the strength of the upper of the clogs. Moreover, the formed holes and recesses are free of burrs, which can save time and cost, greatly increase production capacity and efficiency, and improve competitiveness.

[0022] Furthermore, the bump group 21 includes a first bump 211 and a plurality of second bumps 212 arranged around the first bump 211. The tops of the first bump 211 and the second bump 212 are both in contact with the outer mold 1. The plurality of first protrusions 111 are respectively located between the second bumps 212. The first bump 211, the second bump 212, and the first protrusion 111 form a shape forming area, and the shape forming area has a petal-shaped structure.

[0023] Specifically, it can be understood that the first protrusion 211 is the central area of ​​the petals, and the plurality of second protrusions 212 arranged around the first protrusion 211 are the petal areas, and the plurality of first protrusions 111 are respectively located between the second protrusions 212, and the recesses formed by the first protrusions 111 and the holes formed by the second protrusions 212 can cooperate to form the structure of the petals. Of course, the operator can also use the first protrusion 211, the second protrusion 212, and the first protrusion 111 to form other different shapes.

[0024] Preferably, in each shape forming area, there are four second protrusions 212 and four first protrusions 111. That is to say, with the first protrusion 211 as the center, there are eight petals in total. Of course, the operator can also set the number of petals according to actual conditions.

[0025] In this embodiment, the first protrusion 211 and the second protrusion 212 are both made of plastic steel, and the first protrusion 111 is made of aluminum alloy. The first protrusion 211 and the second protrusion 212 made of plastic steel can make the formed holes free of burrs, and no manual subsequent burr cleaning is required; while the first protrusion 111 made of aluminum alloy can effectively transfer heat to the injection molding material, help the plastic to quickly cool and solidify, and improve production efficiency.

[0026] Optionally, third protrusions 213 are further provided on both sides of the mold core 2 . The third protrusions 213 are located in the cavity 3 . A column 2131 coaxially arranged therewith is provided on the third protrusion 213 , and the top of the column 2131 abuts against the outer mold 1 .

[0027] The third protrusion 213 and the column 2131 cooperate to form the shoelace installation hole of the hole shoe.

[0028] Furthermore, a groove 214 is provided at the bottom of the mold core 2, and the groove 214 is used to form the first anti-skid pattern of the insole. In this way, it is not necessary to process the first anti-skid pattern of the insole after injection molding, and the anti-skid pattern and the shoe are integrally formed, so that the anti-skid pattern is not easy to fall off.

[0029] Optionally, there are five convex block groups 21. Of course, there can be more than five or less than five. The specific number can be selected according to the actual needs. It should be noted that the number of convex block groups 21 should also be selected according to the size of the clogs upper.

[0030] In this embodiment, the outer mold 1 includes an upper mold 11 and a lower mold 12, and the mold core 2 is installed between the upper mold 11 and the lower mold 12. The upper mold 11, the lower mold 12, and the mold core 2 form a cavity 3 for forming the hole shoes. In actual use, the mold core 2 is installed on the lower mold 12, and then the upper mold 11 can be moved to assemble with the lower mold 12. After the assembly is completed, the upper mold 11, the lower mold 12, and the mold core 2 form a cavity 3 for forming the hole shoes.

[0031] Preferably, a plurality of second protrusions 121 are provided on the lower mold 12 . The second protrusions 121 are located in the cavity 3 . The second protrusions 121 are used to form the second anti-slip pattern of the sole of the clogs.

[0032] With this design, the holes, recesses, shoelace mounting holes, first anti-slip patterns, and second anti-slip patterns on the hole shoes can all be formed in one injection molding, without the need for additional processing after molding, and the integrity is stronger.

[0033] In this embodiment, the upper mold 11 is provided with a material input channel 112 communicating with the cavity 3. When working, the external injection molding material output mechanism can guide the injection molding material into the cavity 3 through the material input channel 112 on the upper mold 11.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
