Description

Technical Field

[0001] The present application relates to the field of sole mold design, and in particular to an integrated molding mold for a sole with a support plate. Background Art

[0002] In the process of making soles, such as those of sports shoes or hiking shoes, a support plate made of TPU material or carbon fiber material is usually added to the middle of the sole to enhance the toughness and strength of the sole, while making the sole highly elastic, extending the service life, and reducing deformation over a long period of time.

[0003] The manufacturing process of this type of sole is usually as follows: the sole is divided into an upper sole and a lower sole, the upper sole and the lower sole are first formed separately, and then a prefabricated support plate is installed between the upper sole and the lower sole, and the three are connected and fixed to each other by bonding or hot pressing. However, this manufacturing method requires the use of two sets of molding molds to form the upper sole and the lower sole separately, which is costly, and under the bonding method, there is a debonding and cracking between the support plate and the upper sole and the lower sole, which affects the overall strength of the sole. Utility Model Content

[0004] Based on this, the present application provides an integrated molding mold with a support plate sole, which can enable the support plate to be integrally molded with the sole in the mold, thereby reducing production costs and maintaining good strength of the sole.

[0005] The one-piece molding die with a support plate sole provided in the present application adopts the following technical solution:

[0006] An integrated molding mold with a support plate sole comprises a first mold base and a second mold base, wherein a molding space is formed between the first mold base and the second mold base; a first limit member and a second limit member for positioning and installing the support plate are arranged inside the molding space, and the first limit member and the second limit member are respectively arranged on opposite sides of the first mold base and the second mold base.

[0007] By adopting the above-mentioned technical solution, the present application sets a first limit member and a second limit member to jointly position the support plate. When the first mold base and the second mold base are closed, the support plate can be suspended and fixed inside the molding space. After the subsequent operators inject foaming particles into the molding space and foam them, the prepared sole can directly wrap the support plate, thereby realizing the one-piece molding of the sole and maintaining good structural strength of the sole.

[0008] Optionally, the first limit member includes an integrally formed first column and a second column, the outer diameter of the first column is larger than the outer diameter of the second column; the first limit member is fixed to the first mold base through the first column, and the support plate is provided with a through hole for the second column to match and pass through.

[0009] By adopting the above-mentioned technical solution, by making the outer diameter of the first cylinder larger than the outer diameter of the second cylinder, a step surface can be formed between the first cylinder and the second cylinder, and the perforated sleeve of the support plate is arranged on the second cylinder, so that the support plate can be pressed against the step surface; and then after the first mold base and the second mold base are molded together, the second limit member can further press against the support plate, forcing the support plate to press against the step surface, thereby limiting the movement of the support plate inside the molding space, so as to facilitate the smooth molding of the sole.

[0010] Optionally, there are a plurality of first position limiting members, and the first position limiting members are arranged at intervals on the first mold base.

[0011] By adopting the above technical solution, by setting a plurality of first limiting members, and the support plate correspondingly opening a plurality of through holes matching the number of the first limiting members, the support plate can be installed more stably in the molding space by multi-point support positioning.

[0012] Optionally, the first mold base is provided with a molding cavity for forming a molding space, a molding base is movably installed inside the molding cavity, the molding base is adapted to the shape of the molding cavity, and the molding base is provided with avoidance holes for each first limit member to pass through; an extension portion is fixed to the side of the molding base away from the second mold base, the extension portion is penetrated to the side of the first mold base away from the second mold base, and the extension portion is slidably connected to the first mold base through a sliding positioning structure.

[0013] By adopting the above technical scheme, when the sole is foamed and molded, the molding base is allowed to stay on the inner bottom wall of the molding cavity, so that the molding base can be used as an inner mold of the molding space; after the foaming particles are foamed and molded, the first mold base and the second mold base are separated, and the foamed sole will stick to the molding base. By forcing the molding base to move in a direction away from the inner bottom wall of the molding cavity, the convenience of demolding and unloading the foamed sole can be improved, and the labor intensity of the operators can be reduced.

[0014] Optionally, the sliding positioning structure includes a positioning column and an elastic member, the positioning column is fixed to the side of the first mold base away from the second mold base, and the extension part is slidably mounted on the positioning column; the elastic member is arranged between the extension part and the first mold base, and is used to force the extension part to move in a direction away from the first mold base. At this time, the molding base is against the inner bottom wall of the molding cavity, and the molding mold is in use.

[0015] By adopting the above technical solution, the extension part of the molding base is movably sleeved on the positioning column, and the extension part can move in the direction away from the first mold base under the elastic force of the elastic member, so that the molding base is against the inner bottom wall of the molding cavity to serve as the inner mold of the molding space. After foam molding and the first mold base and the second mold base are separated, by forcing the extension part to move in the direction close to the first mold base and squeezing the elastic member, the molding base and the foamed sole can be moved together toward the opening side of the molding cavity, so as to facilitate the demoulding and disassembly of the foamed sole; and during the movement of the first mold base, the first limiting member remains stationary relative to the molding base, which can facilitate the foamed sole to be separated from each first limiting member, further improving the convenience of demoulding the foamed sole.

[0016] Optionally, the sliding positioning structure also includes a driving component arranged between the extension portion and the first mold base, the fixed end of the driving component is connected to the first mold base, and the movable end of the driving component is connected to the extension portion; the movable end of the driving component is in a normally extended state.

[0017] By adopting the above-mentioned technical solution, a driving component is set to control the relative movement between the extension part and the first mold base. After the foamed sole is formed, the movable end of the driving component is retracted inward, which can automatically force the extension part to move in the direction close to the first mold base, and then the foamed sole can automatically move toward the opening side of the molding cavity. There is no need for personnel to manually force the molding base to move, thereby further improving the convenience of foamed sole molding.

[0018] Optionally, the second limiting member includes at least two abutment blocks, and each abutment block is arranged at intervals on the second mold base.

[0019] By adopting the above-mentioned technical solution, by setting the number of abutment blocks to at least two, the abutment blocks arranged at intervals can abut against the support plate over a larger area, which is beneficial to further improve the stability of the support plate and reduce the possibility of the support plate being deformed by force when foamed particles are subsequently injected into the molding space.

[0020] Optionally, the size of the abutment block gradually decreases from a side of the abutment block close to the second mold base to a side away from the second mold base.

[0021] By adopting the above technical solution, this setting can make the abutment block have a draft angle. When the second mold base is separated from the first mold base, the abutment block can smoothly separate from the foamed sole, so that the foamed sole can be smoothly adhered to the first mold base, so as to facilitate the subsequent smooth demolding of the foamed sole.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By arranging the first stopper and the second stopper to jointly position the support plate, when the first mold base and the second mold base are molded together, the support plate can be suspended and fixed in the molding space, so as to facilitate the integrated molding of the sole and the support plate, while maintaining good structural strength of the sole;

[0024] 2. By making the outer diameter of the first column larger than the outer diameter of the second column, a step surface can be formed between the first column and the second column, thereby facilitating the positioning of the support plate; and then after the first mold base and the second mold base are molded together, the second limiter can further abut against the support plate, forcing the support plate to abut against the step surface, so as to facilitate the smooth molding of the sole;

[0025] 3. By movably installing the molding base in the molding cavity, the foaming particles will stick to the molding base after foaming and molding. By forcing the molding base to move away from the bottom wall of the molding cavity, the convenience of demoulding and unloading the foamed sole can be improved, and the labor intensity of the operators can be reduced.

The first stopper 11 and the second stopper 21 are respectively arranged on opposite sides of the first mold base 1 and the second mold base 2. In this embodiment, the first stopper 11 is fixed to the inner bottom wall of the molding cavity 12, and the second stopper 21 is correspondingly fixed to the side of the molding convex mold 22; in another feasible embodiment, the second stopper 21 can also be fixed to the inner bottom wall of the molding cavity 12, and the first stopper 11 is correspondingly fixed to the side of the molding convex mold 22.

By sleeve-fitting the sleeve hole of the extension part 41 on the positioning column 51, the extension part 41 can move along the axial direction of the positioning column 51, thereby enabling the molding base 4 to move smoothly in the molding cavity 12.

[0045] An end of the positioning column 51 away from the first mold base 1 is provided with an integrally formed end cap 511, the outer diameter of the end cap 511 is larger than the outer diameter of the positioning column 51, and can limit the extension portion 41 from detaching from the positioning column 51; the elastic member 52 is configured as a hard spring and is sleeved on the positioning column 51, one end of the elastic member 52 abuts against the first mold base 1, and the other end of the elastic member 52 abuts against the extension portion 41; the setting of the elastic member 52 is used to force the extension portion 41 to move in the direction away from the first mold base 1, at which time the molding base 4 can abut against the inner bottom wall of the molding cavity 12, so that the molding mold is in use.

[0046] It should be noted that the use state referred to here refers to the state in which foaming particles can be injected into the molding space to make the foam sole foamed and molded smoothly; at this time, the first column 111 partially exposes the molding base 4. In addition, after the foam sole is foamed and molded, by forcing the extension part 41 to move in the direction close to the first mold base 1 and squeezing the elastic member 52, the foam sole can be smoothly separated from each first limit member 11; and then the foam sole moves to the opening side of the molding cavity 12, which can facilitate the demoulding and unloading of the foam sole and reduce the labor intensity of the operator.

[0047] In addition, refer to Figure 5The positioning column 51 is provided with a mounting groove 512, which extends along the circumferential direction of the positioning column 51, and a limit stopper 513 is rotatably embedded in the mounting groove 512, and the limit stopper 513 can slide a certain distance in the mounting groove 512 and along the circumferential direction of the positioning column 51; when the molding mold is in use, the limit stopper 513 can abut against the side of the extension portion 41 close to the first mold base 1 to limit the free sliding of the extension portion 41 on the positioning column 51.

[0048] The extension portion 41 is provided with a through groove 411 for the limit stopper 513 to match and pass through. When the operator moves the limit stopper 513 to one side end wall of the installation groove 512, the limit stopper 513 can be set opposite to the through groove 411. At this time, the extension column can smoothly pass through the limit stopper 513, thereby facilitating the demoulding and unloading of the foamed sole. Example 3
