Description

Technical Field

[0001] This utility model belongs to the technical field of shoemaking auxiliary tools, and relates to an insertable shoe last back collar arc shaping mold and shoe last. Background Technology

[0002] In the process of shoe design and prototyping or handmade shoe production, in order to optimize the wearing and taking-off experience and fit the contours of the foot, an arc-shaped structure is usually designed above the heel counter, forming the arc of the heel counter collar. The top of the heel counter is cut into a U-shape or V-shape to form a soft entrance that conforms to the curve of the Achilles tendon, allowing the heel to slide in instantly when putting on the shoe, avoiding friction between hard materials and the ankle.

[0003] To avoid repeated rubbing of the heel against the seams of the heel counter when putting on and taking off shoes, the top of the heel counter usually features an outward-curving edge design. This keeps the edge of the rigid material away from the Achilles tendon skin, allowing the heel to slide in along the bevel when putting on the shoe, eliminating friction points from the sharp edges. This design has become a common standard in modern footwear, balancing functionality and comfort. The shape of the heel counter depends on the shoe last, but existing shoe lasts, such as... Figure 1 As shown, the heel area lacks a support structure to prevent the top edge of the heel counter from turning outwards. Therefore, the existing shoe last needs to be improved to provide support and shape the outward-turning edge of the heel counter. Summary of the Invention

[0004] The purpose of this utility model is to provide an insertable shoe last collar curve shaping mold. This utility model can fit the existing shoe last and play a shaping role in the outward turning of the collar curve at the top of the shoe collar, thereby improving the smoothness of putting on and taking off the shoes. The second objective of this invention is to provide a shoe last that can also help to shape the outward-turning edge of the collar curve at the top of the heel counter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An insertable shoe last back collar curve shaping mold, comprising a long strip-shaped arc plate; The inner surface of the curved plate is adapted to the back of the shoe last; The upper part of the outer surface of the arc plate has a protrusion that causes the curved edge of the heel collar of the shoe to turn outward.

[0006] As a limitation, the thickness of the arc-shaped plate gradually decreases from top to bottom.

[0007] As a second limitation, the width of the arc-shaped plate decreases from top to bottom.

[0008] As a third limitation, a horizontal baffle is provided at the top of the inner surface of the arc-shaped plate.

[0009] As a fourth limitation, the outer surface and protrusions of the arc-shaped plate are polished and sanded, resulting in a smooth surface.

[0010] A shoe last, wherein the upper part of the back of the shoe last is provided with a protrusion in the aforementioned insertable shoe last back neckline shaping mold, which causes the edge of the back neckline curve to turn outward.

[0011] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned technical solution, are as follows: (1) This utility model ensures the stability of the mold by precisely matching the inner surface of the arc plate with the shoe last. The mechanical guidance of the raised outer surface allows the shoe upper material to turn out naturally, eliminating the process error of traditional manual folding. Secondly, the modular design of the mold can be adapted to shoe lasts with different curvatures, significantly improving the standardization of production. (2) In this utility model, the thickness of the arc plate gradually decreases from top to bottom, and the gradual thickness forms a natural transition slope, so that the shoe upper material obtains gradient shaping force during the shaping process; the thin lower end ensures seamless connection between the mold and the shoe last, preventing the common problem of seam indentation in traditional molds. (3) The design of the arc plate width is added to this utility model. The trapezoidal outline with the upper width and lower width matches the natural taper of the human calf-Achilles tendon. The guide slope formed by the gradually narrowing width significantly improves the injection molding demolding efficiency and reduces the mold wear rate. The wide top enhances the stability of the shoe collar wrapping, while the narrow bottom reduces the friction of the material on the Achilles tendon. (4) This utility model adds a baffle at the top. When working, you can insert the mold from top to bottom into the back part of the shoe last until the baffle contacts the shoe last. The operation is simple and quick and convenient.

[0012] This utility model belongs to the field of shoemaking auxiliary tools technology. It can fit the existing shoe last and play a shaping role in the outward turning of the edge of the back collar curve at the top of the shoe, thereby improving the smoothness of putting on and taking off the shoes.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example 1 like Figure 2 and Figure 3 As shown, this embodiment is an insertable shoe last collar curve shaping mold, including a long strip arc plate 1. The inner surface of the arc plate 1 is adapted to the back of the shoe last, and the upper part of the outer surface of the arc plate 1 is provided with a protrusion 2 that makes the edge of the collar curve of the shoe back turn outward.

[0018] To make it easier to insert the curved plate 1 into the back of the shoe last from top to bottom during use, the thickness of the curved plate 1 gradually decreases from top to bottom, and the width of the curved plate 1 gradually decreases from top to bottom.

[0019] For ease of installation during use, a horizontal baffle 3 is provided at the top of the inner surface of the curved plate 1.

[0020] The outer surface of the curved plate 1 and the protrusions 2 are polished and sanded, resulting in a smooth surface that reduces friction when inserting this embodiment during use.

[0021] like Figure 4 As shown, in this embodiment, during use, hold the upper end of the curved plate 1 and insert it into the back of the shoe last, aligning the inner surface of the curved plate 1 with the back of the shoe last, until the baffle 3 at the top of the curved plate 1 is released from the shoe last. At this time, the protrusion 2 on the outer surface of the curved plate 1 precisely shapes the arc of the back collar of the shoe into an outward-turned state, thereby achieving the function of outward-turning shaping.

[0022] It should be noted that the design of the curved plate 1, which is wider at the top and narrower at the bottom, in this embodiment allows the curved plate 1 to fit snugly against the back of the shoe last when inserted, and it is securely fixed after insertion and is not easy to fall out.

[0023] In summary, this embodiment can fit existing shoe lasts and shape the outward-turning edge of the heel collar curve at the top of the heel counter, thereby improving the smoothness of putting on and taking off the shoes.

[0024] Example 2 like Figure 5As shown, this embodiment is a shoe last. In this embodiment, the upper part of the heel counter is provided with a protrusion that makes the curved edge of the heel counter turn outward as described in Embodiment 1.
