Technical Field
[0001] This utility model belongs to the field of shoemaking, specifically relating to a shoe heel tilting mold. Background Technology
[0002] In today's society, as people's pursuit of a high-quality material and cultural life continues to rise, higher demands are being placed on the wearing experience of footwear products. This is reflected not only in the comfort and aesthetics of shoes, but also in the ease of putting them on and taking them off. To meet this demand, many cleverly designed shoes have appeared on the market, featuring a heel lift with a backward tilt, such as... Figure 6 As shown in the circle, this design makes putting on shoes faster and also allows for convenient putting them on with the carrying handle. While improving the ease of putting on and taking off shoes, this design also presents new challenges to the shoe manufacturing process.
[0003] When producing shoes with a raised heel design, the heel area requires heat setting and cold setting processes to ensure the stability of the shoe's shape and size. However, in traditional heel setting molds (such as...) Figure 5 When operating on the mold (as shown), wrinkling and deformation often occur at the heel collar due to the lack of a corresponding support structure on the mold. This not only affects the appearance quality of the shoe but also reduces the market competitiveness of the finished product. To solve this problem, we researched and developed a new type of backward-leaning shaping mold. Utility Model Content
[0004] To address the problem that existing molds lack corresponding support structures for heel lifting, this utility model provides a shoe heel tilting mold.
[0005] The purpose of this utility model is achieved in the following way: a shoe heel tilting mold, including a bottom mold 1, an adjustment mold 2 is provided above the bottom mold 1, and the rear end of the adjustment mold 2 extends backward from low to high, and the extended part forms a tilting mold 21;
[0006] A tensioning structure is provided between the bottom mold 1 and the adjusting mold 2, and the tensioning structure forms a tensioning fixation between the bottom mold 1 and the adjusting mold 2.
[0007] The molding die 2 is provided with an ejection structure, which changes the distance between the corresponding position of the molding die 2 and the bottom die 1.
[0008] This allows the angle between the bottom mold 1 and the adjusting mold 2 to be changed through the cooperation of the tensioning structure and the ejection structure.
[0009] Furthermore, a first threaded cylinder 3 is fixedly connected inside the bottom mold 1. The first threaded cylinder 3 forms an opening at the top of the bottom mold 1. A strip-shaped through hole 22 is provided in the shaping mold 2 in the front-back direction corresponding to the position of the first threaded cylinder 3. The two ends of the strip-shaped through hole 22 are located at the top and bottom of the shaping mold 2, respectively. The first threaded cylinder 3 is threadedly connected to the body of a positioning screw 31. The head end of the positioning screw 31 passes through the strip-shaped through hole 22 and abuts against the top of the shaping mold 2.
[0010] Furthermore, a shim 32 is provided between the head end of the positioning screw 31 and the top of the shaping mold 2.
[0011] Furthermore, a second threaded cylinder 4 is fixedly connected inside the shaping mold 2 in front of the strip-shaped through hole 22. The second threaded cylinder 4 is threadedly connected to an ejector screw 41, and a locking nut 42 is threadedly connected to the ejector screw 41. The bottom of the ejector screw 41 abuts against the top surface of the shaping mold 2.
[0012] Furthermore, the bottom of the ejector screw 41 is fixedly connected to the top block 43, and the top block 43 abuts against the top surface of the molding die 2.
[0013] Furthermore, the bottom mold 1 has a positioning inner arc surface 11 extending backward from low to high at the top rear end, and the shaping mold 2 has a positioning outer arc surface 23 that cooperates with the positioning inner arc surface 11 at the bottom rear end, with the positioning inner arc surface 11 and the positioning outer arc surface 23 abutting against each other.
[0014] Compared to existing technologies, this utility model features a rear tilting mold for the lifting structure, which provides support during hot and cold setting processes. In addition, by cooperating with the pulling structure and the ejection structure, the angle between the bottom mold and the adjusting mold is changed, thereby changing the angle of the rear tilting mold to suit the production needs of different lifting angles.

Therefore, they should not be construed as limitations on this utility model.
[0024] The heel features a lift design with a backward tilt, such as... Figure 6 As shown in the circle, this design makes putting on shoes faster and also allows for convenient slipping on via a carrying handle. When producing these shoes with a raised heel, the heel portion requires heat-setting and cold-setting processes to ensure the shoe's shape and size stability. However, traditional heel-setting molds, such as... Figure 5 When operating as shown, wrinkles and deformation often occur at the heel neckline because there is no corresponding support structure on the mold.
[0025] As attached Figure 1-4 As shown, a shoe heel tilting mold includes a bottom mold 1, the shape of which corresponds to the heel part of the shoe cavity. A shaping mold 2 is provided above the bottom mold 1. The rear end of the shaping mold 2 extends backward from low to high, and the extended part forms a tilting mold 21. The tilting mold 21 is preferably a concave arc-shaped structure, corresponding to the heel lifting structure that fits during processing.
[0026] A tensioning structure is provided between the bottom mold 1 and the adjusting mold 2, and the tensioning structure forms a tensioning fixation between the bottom mold 1 and the adjusting mold 2.
[0027] The molding die 2 is provided with an ejection structure, which changes the distance between the corresponding position of the molding die 2 and the bottom die 1.
[0028] This allows the angle between the bottom mold 1 and the adjusting mold 2 to be changed by coordinating the pulling structure and the ejection structure, thereby changing the angle of the rear tilting mold.
[0029] Furthermore, a first threaded cylinder 3 is fixedly connected inside the bottom mold 1. The first threaded cylinder 3 forms an opening at the top of the bottom mold 1. A strip-shaped through hole 22 is provided in the shaping mold 2 in the front-back direction corresponding to the position of the first threaded cylinder 3. The two ends of the strip-shaped through hole 22 are located at the top and bottom of the shaping mold 2, respectively. The first threaded cylinder 3 is threadedly connected to the body of a positioning screw 31. The head end of the positioning screw 31 passes through the strip-shaped through hole 22 and abuts against the top of the shaping mold 2.
[0030] The first threaded cylinder 3 is preferably a steel cylindrical structure with internal threads on the inner wall. A hole is made at the top of the bottom mold 1 and the first threaded cylinder 3 is inserted and further fixed by adhesive bonding or other methods.
[0031] The width of the strip-shaped through hole 22 is greater than the width of the threaded rod of the positioning screw 31, but less than the minimum width of the head end of the positioning screw 31.
[0032] The top of the mold 2 is limited by the head end of the positioning screw 31, and the mold 2 is pulled. As the angle of the mold 2 changes, the head end of the positioning screw 31 and the top surface of the mold 2 gradually become in line contact or even point contact. Long-term use will cause indentation and damage to the mold. Therefore, preferably, a shim 32 is provided between the head end of the positioning screw 31 and the top of the mold 2. The shim 32 can be a rubber shim 32 or other soft shims.
[0033] Furthermore, a second threaded cylinder 4 is fixedly connected inside the shaping mold 2 in front of the strip-shaped through hole 22. The second threaded cylinder 4 is threadedly connected to an ejector screw 41, and a locking nut 42 is threadedly connected to the ejector screw 41. The bottom of the ejector screw 41 abuts against the top surface of the shaping mold 2.
[0034] The structure of the second threaded cylinder 4 is the same as that of the first threaded cylinder 3. It moves downward through the ejector screw 41 and abuts against the top of the bottom mold 1 to support the shaping mold 2. Similarly, in order to prevent indentation and damage to the mold, the bottom of the ejector screw 41 is preferably fixedly connected to the top block 43. The top block 43 abuts against the top surface of the shaping mold 2. The top block 43 is preferably made of spherical rubber or other soft material. The bottom mold 1 and / or the shaping mold 2 should be provided with a cavity to accommodate the top block 43.
[0035] When adjusting the angle, see attached Figure 3-4As shown, first screw the positioning screw 31 outward, then screw the ejector screw 41 inward to determine the front end distance between the bottom mold 1 and the adjusting mold 2, and then screw the positioning screw 31 in to press the rear end of the adjusting mold 2 to change the angle between the bottom mold 1 and the adjusting mold 2, so as to determine the angle of the rear tilting mold 21.
[0036] The above structure allows for angle adjustment, but the fixed relationship between the bottom mold 1 and the adjusting mold 2 relies heavily on the friction of their contact parts, resulting in poor stability. Therefore, the bottom mold 1 is further provided with a positioning inner arc surface 11 extending backward from low to high at the top rear end. The positioning inner arc surface 11 is concave inward, and the adjusting mold 2 is provided with a positioning outer arc surface 23 that mates with the positioning inner arc surface 11 at the bottom rear end. The positioning outer arc surface 23 is convex outward, and the positioning inner arc surface 11 and the positioning outer arc surface 23 abut against each other.
[0037] At this time based on Figure 4 Force analysis shows that at the positioning inner arc surface 11 and the positioning outer arc surface 23, the bottom mold 1 provides an upward and rightward support force to the adjusting mold 2. At the ejection screw 41, the bottom mold 1 provides an upward and leftward support force to the adjusting mold 2. In the middle, the bottom mold 1 provides a downward pulling force to the adjusting mold 2 through the positioning screw 31, at which point the structure is more stable.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
