[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-2 As shown, a shoemaking mold of an embodiment of the present invention includes a lower template 2 and an upper template 1 hinged to the lower template 2, the upper template 1 has an upper mold cavity 10 and the top surface of the upper template 1 has an injection hole 11 connected to the upper mold cavity 10, the lower template 2 is formed with a lower mold cavity 20, the lower template 2 is located on both sides of the lower mold cavity 20 and has two movable recesses 21 correspondingly formed thereon, a through hole 22 is formed between the two movable recesses 21 and the lower mold cavity 20, a mating mold base 3 is slidingly provided in the two movable recesses 21, and the two mating mold bases 3 are formed with abutments 30 adapted to the through holes 22 on opposite sides. When the upper template 1 and the lower template 2 are closed, the two abutments 30 synchronously pass through the through holes 22 and abut against each other.

[0022] When using, refer to the instructions attached. Figure 2 At this time, the mold is in the open state. When working, the upper template 1 and the lower template 2 are controlled to close. When the upper template 1 and the lower template 2 are closed, the two mating mold bases 3 are prompted to slide toward each other along the corresponding active concave positions 21. When the upper template 1 and the lower template 2 are completely closed, the two mating mold bases 3 also reach the final position. At this time, the abutment blocks 30 of the two mating mold bases 3 are completely abutted against each other, and the upper mold cavity 10 and the lower mold cavity 20 are closed to form a molding cavity. The injection molding material is injected into the molding cavity through the injection hole 11 to complete the molding of the sole. The mold is opened to take out the finished sole 6.

[0023] See the instructions attached Figure 5 , is the finished sole product 6 obtained by molding, the middle part of the sole is formed with an elastic cavity, which is formed by the two abutting blocks 30;

[0024] The utility model has a simple structure and is convenient for opening a mold. The sole is formed in one step, and no seams that affect the appearance appear on the surface of the sole. The product is not easy to crack and has a long service life.

[0025] Two sliding parts 31 are formed on the front and rear sides of the mating mold base 3 , and limiting parts 32 are formed on the opposite sides of the two sliding parts 31 . Limiting grooves 33 that match the limiting parts 32 are formed on the front and rear sides of the bottom of the movable recess 21 .

[0026] When in use, the mating mold base 3 is slidably set in the movable recess 21, and the mating mold base 3 is limited in the vertical direction by the cooperation between the limiting portion 32 and the limiting groove 33, thereby ensuring the smooth sliding of the mating mold base 3 and preventing the mating mold base 3 from separating from the lower mold plate 2 during the sliding process.

[0027] Two guide posts 23 are formed on the side wall separating the movable recess 21 from the lower mold cavity 20, and matching holes 24 are formed on the inner side wall of the matching mold base 3 at the corresponding positions of each guide post 23; the outer ring of the guide post 23 is located between the inner side wall of the movable recess 21 and the matching mold base 3 and a spring part 25 is sleeved.

[0028] During use, the mating mold base 3 automatically returns to its initial position when the mold is opened, and the spring member 25 provides reset kinetic energy for the mating mold base 3. The guide column 23 provides a limit for the spring member 25 to prevent the spring member 25 from being offset or out of the preset position when squeezed or elastically released. The mating hole 24 prevents the guide column 23 and the mating mold base 3 from getting stuck.

[0029] An assembly hole 26 is formed at the center of the inner bottom wall of the movable recess 21 , and a matching groove 28 is formed on the lower surface of the matching mold base 3 at a position corresponding to the assembly hole 26 .

[0030] During use, when installing the mating mold base 3, push it into the movable recess 21, and form a vertical limit on the mating mold base 3 through the cooperation between the limiting portion 32 and the limiting groove 33, and then extend the external fastener 27 from bottom to top into the assembly hole 26 and tighten it. The upper end of the fastener 27 extends out of the fastening hole and forms a limit with the mating groove 28. The maximum distance between the two mating mold bases 3 is limited by the limiting cooperation between the fastener 27 and the mating groove 28, while preventing the mating mold base 3 from being separated from the lower template 2.

[0031] A first mating slope 34 is formed on one end of the mating mold base 3 away from the lower mold cavity 20 , and a pressing block 35 is provided at the upper mold plate 1 corresponding to the two movable recesses 21 , and a second mating slope 36 adapted to the first mating slope 34 is formed on the inner side of the pressing block 35 .

[0032] During use, when the upper mold plate 1 and the lower mold plate 2 are closed, the pressure block 35 cooperates with the second mating inclined surface 36 and the first mating inclined surface 34, prompting the two mating mold bases 3 to overcome the force of the spring member 25 and move toward each other along the movable recess 21. When the upper mold plate 1 and the lower mold plate 2 are opened, the two mating mold bases 3 retreat to their initial positions due to the release of the stored energy of the spring member 25.

[0033] A clamping rib 4 is formed at the front end of the lower template 2, and a clamping head 40 adapted to the clamping rib 4 is rotatably provided on the upper template 1. A gripping handle 5 is also provided at the front end of the upper template 1.

[0034] During use, when the upper mold plate 1 and the lower mold plate 2 are closed, the clamping head 40 and the clamping rib 4 engage to lock the closed state; the gripping handle 5 provides a stable fulcrum for opening and closing the mold.

[0035] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
