Description

Technical Field

[0001] This utility model relates to the field of shoemaking, specifically a mold for pressing Goodyear soles. Background Technology

[0002] When extruding the upper and sole, the upper and sole are typically placed together on a mold that matches the shape of the sole, and an extrusion tool is used to tightly bond them together. For example... Figure 1 As shown, the upper surface 3 of a standard mold is flat and has textured surfaces 5 to increase friction. It also has sidewalls 4 around the mold to limit the size of the shoe sole that can be placed on it. However, when pressing larger shoe soles, the sidewalls 4 prevent the sole from being placed flat on the upper surface 3 of the mold, requiring a larger mold to meet the actual needs. Therefore, a standard mold cannot accommodate different sizes of shoe soles simultaneously. When pressing shoes of different sizes, different sized molds must be used, making the processing quite cumbersome.

[0003] Goodyear welt soles are a type of sole manufactured using a special sole-making process, such as... Figure 2 As shown, one type of Goodyear welted sole has a heel that protrudes downwards from the bottom of the sole. If the upper and Goodyear sole are pressed together using a conventional mold, the lower surface of the sole cannot fully adhere to the upper surface of the mold, resulting in insufficient stress on the lower surface of the sole. Simultaneously, because the upper surface of the conventional mold has texture, the lower surface of the sole also cannot fully adhere to the upper surface of the mold during downward pressing, causing insufficient stress on the lower surface of the sole. Therefore, the adhesion between the sole and upper of shoes produced using conventional molds is insufficient. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a mold for Goodyear shoe sole pressing, which can press shoes of different sizes and, during the pressing process of the sole and upper, ensures that the lower surface of the sole is fully stressed, thereby improving the adhesion between the sole and the upper.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mold for pressing Goodyear soles, comprising a foot-shaped sheet plate, the upper surface of which is a stepped shape with a smooth surface, and the height of the front part of the sheet plate is higher than the height of the rear part of the sheet plate.

[0006] As a limitation of this utility model: the front part of the upper surface of the sheet plate is a downward curved surface, and the rear part of the upper surface of the sheet plate is a horizontal surface.

[0007] As a limitation of this utility model: a protrusion higher than the front part of the upper surface of the sheet plate is fixedly provided in the middle part of the upper surface of the sheet plate along the width direction of the mold used for Goodyear shoe sole pressing.

[0008] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: by removing the sidewalls of the ordinary mold in the prior art, the sole can still be placed flat on the upper surface of the mold when the sole size increases. When pressing shoes of different sizes, there is no need to change the mold of different sizes, which simplifies the processing process.

[0009] By setting the plate, whose upper surface is a smooth flat surface, into a stepped shape, a recessed area for placing the heel of the Goodyear sole is formed at the rear of the plate. Furthermore, the texture on the upper surface of the conventional mold is removed. When the upper and sole placed on the upper surface of the plate are pressed down, the lower surface of the sole can fully contact the upper surface of the plate, thereby allowing the lower surface of the sole to bear full force and improving the adhesion between the sole and the upper.

[0016] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the mold for Goodyear shoe sole pressing described herein is a preferred embodiment and is only used for illustration and explanation of this utility model, and does not constitute a limitation thereof.

[0017] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0018] A mold for Goodyear welt sole pressing, such as Figure 3 and Figure 4As shown, it includes a foot-shaped sheet 1 with a smooth upper surface. Figure 3 The upper part of the plate is the front part of the sheet plate 1. Figure 4 The left side of the image shows the front of sheet plate 1. The upper surface of sheet plate 1 is stepped, and the height of the front part of the upper surface of sheet plate 1 is higher than the height of the rear part of the upper surface of sheet plate 1. A recessed area is formed at the rear of sheet plate 1 for placing the heel of the Goodyear sole. When the upper and sole placed on the upper surface of sheet plate 1 are pressed down, the lower surface of the sole can fully contact the upper surface of sheet plate 1, thereby ensuring that the lower surface of the sole is fully stressed and improving the adhesion between the sole and the upper. Since there are no sidewalls around the upper surface of sheet plate 1, when the sole size increases, although the outline of the sole will slightly protrude from the outline of sheet plate 1, the sole can still lie flat on the upper surface of sheet plate 1, thus allowing the mold to accommodate soles of different sizes simultaneously. Therefore, when the sole size increases, the sole can still be placed flat on the upper surface of the mold. When pressing shoes of different sizes, it is not necessary to change to molds of different sizes, simplifying the processing.

[0019] To adapt to the contours of the foot, the front of the sole is typically curved downwards. Therefore, the front of the upper surface of the sheet plate 1 is a downward-curved surface, while the rear of the upper surface of the sheet plate 1 is a horizontal surface, to better adapt to the shape of the sole, further increasing the contact area between the mold and the sole, and ensuring more sufficient force distribution. To further adapt to the shape of the sole, a trapezoidal protrusion 2, higher than the front of the upper surface of the sheet plate 1, is fixedly provided in the middle of the upper surface of the sheet plate 1 along the width direction of the mold used for Goodyear sole pressing. By placing the front end of the heel against the side of the protrusion 2 near the rear of the sheet plate 1, the sole can be prevented from sliding forward during pressing, improving the bonding effect. When producing shoes of different specifications, the height and shape of the protrusion 2, as well as the curvature of the front surface of the upper surface of the sheet plate 1, can be adjusted accordingly to meet actual needs.

[0020] When in use, place the upper and sole on the upper plate 1, so that the front of the heel touches the side of the protrusion 2 near the back of the plate 1, and use the pressing device to press the upper and sole tightly together.
