Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, and in particular to a footwear molding mold. Background Technology

[0002] In existing shoe manufacturing technology, manufacturers use multiple sets of molds to produce the sole, upper, and heel counter assembly separately, and then weld them together to produce the shoe blank. The blank is then manually processed to achieve a seamless and adhesive-free finish. This method requires manufacturers to combine the elastic component in the heel counter assembly with the heel counter panel in advance when producing the upper and heel counter assembly. Then, other molds are used to further heat the already formed upper and heel counter components and the sole to fuse them together. Existing shoe manufacturing molds cannot directly heat-press the finished shoe with the heel counter, sole, and upper fused together in one step. Utility Model Content

[0003] The purpose of this utility model is to provide a footwear molding mold to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] First, this utility model provides a footwear molding die, comprising:

[0006] A bottom mold, wherein the bottom mold is provided with a mold cavity for forming the shoe sole upper;

[0007] A side mold, which is connected to the bottom mold and opens and closes relative to the bottom mold;

[0008] A shoe last, which is fitted with a shoe cover, is located in a mold cavity. A side mold clamps the shoe cover, and a thin-walled cavity is formed between the side mold, the shoe cover, and the cavity wall of the mold cavity. The thin-walled cavity is divided into a first cavity and a second cavity. The first cavity is located at the lower part of the shoe cover, and the second cavity is located at the rear part of the shoe cover.

[0009] By setting a first cavity and a second cavity that communicate with each other in the molding mold for simultaneously molding the heel counter and the sole, the foaming material foams in the first cavity and the second cavity during the mold closing process and fuses with the shoe cover fitted on the shoe last. Using the mold provided by this utility model, a finished shoe with a heel counter and sole that has moderate elasticity, wear resistance and support can be hot-pressed in one step. The heel counter and sole of the finished shoe produced by the molding mold of this utility model are not easy to separate. Furthermore, since the mold can mold the heel counter, the heel counter part in the shoe cover does not need to be foamed. Only the heel counter circumference needs to be shaped. This mold simplifies the production process of slip-on shoes.

[0010] As an extension of the above solution, the second cavity is inclined or vertically perpendicular to the first cavity, and the bottom of the second cavity is connected to the end of the first cavity. This arrangement allows for better integration of the heel counter and sole in the finished shoe. The connection between the first and second cavities results in a unified heel counter and sole after the foamed material is foamed and molded, which is incomparable to the traditional method of separate production followed by splicing / welding.

[0011] As an extension of the above solution, the second cavity protrudes from the mold cavity and extends rearward. This arrangement allows the finished shoe to have a rearwardly extending protrusion at the heel counter, thereby improving the wearing performance of the finished shoe produced by this mold.

[0012] As an extension of the above solution, the side mold is provided with guide pillars, and the bottom mold is provided with sliding grooves adapted to the guide pillars. The sliding grooves are located on the front and rear end faces of the bottom mold and penetrate the bottom mold in the left-right direction. By providing sliding grooves in the bottom mold itself, the side mold can slide directly relative to the bottom mold to close the mold, which can improve the mold positioning accuracy and make the produced products have higher forming accuracy.

[0013] As an extension of the above solution, the slide groove has a rectangular cross-section. By setting the cross-sections of the slide groove and the guide post to be rectangular, the guide post and slide groove produced by the molding die in one molding process can have high fitting accuracy, and compared with circular guide posts, they are easier to grind to improve mold closing accuracy.

[0014] As an extension of the above solution, the side mold includes a first side mold and a second side mold, which are symmetrically arranged with respect to the centerline of the bottom mold in the left-right direction. By symmetrically arranging the side molds, which open and close relative to the bottom mold, the shoe last can be fitted with both side molds, thereby improving positioning accuracy and facilitating the later removal of the product.

[0015] As an extension of the above solution, the upper middle part of the opposite surfaces of the first side mold and the second side mold are respectively provided with parting surfaces protruding from the side mold. When the mold is closed, the parting surfaces abut against the shoe cover. The parting surfaces divide the space enclosed by the first side mold, the second side mold and the shoe cover into an upper cavity and a lower cavity. The bottom mold is located in the lower cavity, and a part of the shoe cover is located in the upper cavity.

[0016] By placing the bottom mold in the lower cavity of the side mold, and further, making the bottom surface of the bottom mold flush with the bottom surface of the side mold, the overall volume of the shoe forming mold provided by this utility model can be reduced. In daily production, since molds are generally clamped on disc shoe-making machinery for production, reducing the mold volume allows the machine to clamp more molds, thus improving production efficiency. On the other hand, placing the parting surface in the upper middle part of the side mold, so that part of the shoe cover is located in the lower cavity during production, can improve the integrity of the connection. Furthermore, exposing part of the shoe cover in the upper cavity can prevent the exposed part of the shoe cover from being heated. The exposed part of the shoe cover is generally part of the upper and the heel counter, which helps to maintain the performance of the upper, especially for some uppers with special layer structures, without damaging their layer structure.

[0017] As an extension of the above solution, the parting surface has a notch that matches the shape of the shoe last, and the lower edge of the notch is blade-shaped. This design allows the parting surface to fit the shoe last more closely, making the foaming space between the first and second cavities more enclosed, resulting in better integration of the upper and sole components of the finished shoe.

[0018] As an extension of the above solution, a shoe molding mold further includes: a first patterned portion, which is disposed at the bottom of the first cavity. By providing the first patterned portion in the first cavity, anti-slip patterns can be directly formed on the produced shoe sole.

[0019] As an extension of the above solution, a shoe molding mold further includes a second patterned portion, which is disposed on the side wall of the first cavity. By providing the second patterned portion in the first cavity, the side pattern can be directly formed on the produced shoe sole. Attached Figure Description

[0032] Reference Figures 1 to 6 The following are several embodiments of the footwear molding die of this utility model.

[0033] like Figures 1 to 3 , Figure 6 As shown, a footwear molding die includes:

[0034] The bottom mold 107 is provided with a mold cavity 1063 for forming the shoe sole upper;

[0035] A side mold, which is connected to the bottom mold 107 and opens and closes relative to the bottom mold 107;

[0036] A shoe last 200 is fitted with a shoe cover 400. The shoe last 200 is located within the mold cavity 1063, forming a thin-walled cavity between the shoe last 200 and the cavity wall of the mold cavity 1063. The thin-walled cavity is divided into a first cavity 101 and a second cavity 102. The first cavity 101 is located at the lower part of the shoe last 200, and the second cavity 102 is located at the rear part of the shoe last 200. The first cavity 101 and the second cavity 102 communicate with the rear top of the shoe last 200.

[0037] The second cavity 102 is inclined or vertical to the first cavity 101, the bottom of the second cavity 102 is connected to the end of the first cavity 101, and the second cavity 102 protrudes from the mold cavity 1063 and extends rearward.

[0038] The first cavity 101 also includes a patterned portion 104, which is divided into a first patterned portion 1041 and a second patterned portion 1042. The first patterned portion 1041 is located at the bottom of the first cavity 101 and is used to directly generate anti-slip patterns 1043. The second patterned portion 1042 is located on the side wall of the first cavity 101 and is used to directly generate patterns 1044 on the side wall of the shoe sole.

[0039] During production, the molding mold 100 and the shoe last 200 are both mounted on a shoemaking machine. A release agent is sprayed onto the mold cavity 1063 and the shoe last 200. Then, a precisely measured amount of foaming material is placed into the mold cavity 1063. The shoe last 200 is moved into the mold cavity 1063 and placed in the molding mold 100, so that the molding mold 100 forms a first cavity 101 and a second cavity 102 that are connected. Then, the mold is closed, heated, and kept at a certain temperature for a period of time. Pressure is applied to the shoe last 200 so that the foaming material evenly fills the first cavity 101 and the second cavity 102 and is fused with the shoe cover 400 to form a finished shoe 500.

[0040] Since the heel counter 301 and the sole 302 are integrally thermoformed, the heel counter 301 has a certain elasticity and support performance. Therefore, the pre-prepared shoe cover 400 may not include the elastic component in the heel counter assembly of the prior art. That is, the shoe cover 400 may only be a combination of the upper 403, the heel counter lining, and the insole 401. This combination can be directly obtained by weaving fabric. In other words, the shoe molding mold provided by this utility model can produce a pair of finished slip-on shoes in just one thermoforming process.

[0041] By fitting the shoe cover 400 onto the shoe last 200 and placing the finished shoe last 200 into the molding mold 100, the foam material comes into direct contact with the shoe cover 400. The resulting finished shoe 500 does not have the defects of secondary welding and does not require manual repair, so it can be used directly. Since the shoe upper and sole 300 are produced in one piece, their service life is not affected. At the same time, the shoe upper and sole 300 are welded to the shoe cover 400 at high temperature, resulting in better adhesion between the shoe upper and sole 300 and the shoe cover 400, which can improve the service life of the finished shoe 500.

[0042] like Figure 4 As shown, in some embodiments, the side mold is provided with guide posts 1072, and the bottom mold 107 is provided with a sliding groove 1071 adapted to the guide posts 1072. The sliding groove 1071 is provided on the front and rear end faces of the bottom mold 107 and penetrates the bottom mold 107 in the left and right direction. The cross-section of the sliding groove 1071 is rectangular.

[0043] In some embodiments, the side mold includes a first side mold 105 and a second side mold 106, which are symmetrically arranged in the left-right direction relative to the bottom mold 107. By symmetrically arranging the side molds, which open and close relative to the bottom mold, the shoe last can be fitted with both side molds, thereby improving positioning accuracy and facilitating the removal of the product later.

[0044] In daily production, since molds are generally clamped on disc shoe-making machinery for production, reducing the size of the mold is beneficial for the machine to clamp more molds and improve production efficiency. In order to reduce the size of the mold, the upper middle part of the first side mold 105 and the second side mold 106 can be provided with parting surfaces 103 respectively. When the mold is closed, the parting surfaces 103 divide the first side mold 105 and the second side mold 106 into an upper cavity 1062 and a lower cavity 1061, and the bottom mold 107 is located in the lower cavity 1061.

[0045] On the other hand, such as Figure 4As shown, the parting surface 103 is located in the upper middle part of the side mold, so that a part of the shoe cover 400 is located in the lower cavity 1061 during production, which can improve the integrity of the connection. On the other hand, by exposing a part of the shoe cover 400 in the upper cavity 1062, the exposed part of the shoe cover 400 can be protected from heat. The exposed part of the shoe cover 400 is generally a part of the upper 403 and the heel counter 402. This is beneficial to maintaining the performance of the upper 403, especially for some uppers 403 with special layer structures, without damaging their layer structure.

[0046] In order to make the parting surface 103 fit the shoe last 200 better, and to make the foaming space of the first cavity 101 and the second cavity 102 more closed, so that the shoe upper and sole 300 of the finished shoe 500 have better integration, the parting surface 103 is provided with a notch that matches the shape of the shoe last 200, and the lower edge of the notch is blade-shaped (that is, there is an angle between the upper edge and the lower edge of the parting surface 103).

[0047] like Figure 5 As shown, in some embodiments, the shoe molding mold provided by this utility model can be used alone in the molding stage, with the shoe last 200 and the molding mold 100 working together to make the parting surface 103 fit tightly with the shoe last 200, so that the shoe upper bottom part 300, which is integrally formed with the heel counter and the sole, can be produced by foaming and molding alone in one step, and can be used for the production of whole shoes using other processes.

[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
