[0006] The purpose of the utility model can be achieved through the following technical solutions: a shoe upper hot stamping upper mold structure, including an upper mold with a mold cavity, characterized in that it also includes a frame with a rectangular cylindrical structure and a handle that is roughly in an inverted shape, the upper mold is a rectangle that matches the frame, and the upper mold is horizontally arranged in the frame; the mold cavity is arranged at the bottom of the upper mold, and there are multiple mold cavities that are distributed in parallel along the length direction of the frame; both ends of the frame are horizontally penetrated by slide grooves, and the length of the slide grooves extends vertically; sliders are vertically slidably arranged in the two slide grooves, one end of the slider extends into the frame and is fixedly connected to the upper mold, and the other ends of the two sliders are respectively fixedly connected to the two ends of the handle; springs are provided in the two slide grooves to make the corresponding slider have an upward movement tendency.

[0007] In actual products, this upper mold structure is used in conjunction with a lower mold. The lower mold is provided with a punch that matches the mold cavity. The number of the punches and the mold cavity are the same and their positions correspond one to one.

[0008] When in use, the shoe upper is placed on the punch, and the handle is pressed to make the upper template move downward to overcome the spring force, so that the punch extends into the mold cavity to hot-stamp a pattern on the shoe upper; after hot stamping is completed, the handle is released, and the upper template moves up and reset under the action of the spring, exposing the shoe upper after hot stamping for easy taking.

[0009] With the cooperation of components such as a handle, a slider, a spring and an upper template with multiple cavities, the hot stamping of multiple shoe uppers can be completed at one time by pressing the handle, which effectively simplifies the operation steps and has the advantages of ease of use and high efficiency.

[0010] In the above-mentioned upper stamping mold structure for the upper shoe surface, the upper mold structure also includes a limiting structure for limiting the upward movement distance of the upper mold plate, so as to prevent the upper mold plate from excessively moving upward and affecting subsequent use.

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Embodiment 1

[0026] like Figure 1 and Figure 2 As shown, the upper stamping mold structure of the shoe upper comprises an upper mold plate 1 with a mold cavity 1a, a frame body 2 of a rectangular cylindrical structure and a handle 3 which is roughly in the shape of an inverted U.S. dollar.

[0027] in,

[0028] The upper template 1 is a rectangle matching the frame 2, the upper template 1 and the frame 2 have the same length extension direction, and the upper template 1 is horizontally arranged in the frame 2. Preferably, the cross-sectional size of the upper template 1 is slightly smaller than the inner cavity size of the frame 2 to ensure that the upper template 1 slides up and down stably in the frame 2.

[0029] like Figure 2As shown, the mold cavity 1a is set at the bottom of the upper mold plate 1, and there are multiple mold cavities 1a and they are distributed in parallel along the length direction of the frame 2. Both ends of the frame 2 are horizontally penetrated by slide grooves 2a, and the two slide grooves 2a are distributed in parallel along the length direction of the frame 2, and the length of the slide grooves 2a extends vertically. Slide blocks 4 matching the slide grooves 2a are provided in the two slide grooves 2a, and the slide blocks 4 can slide vertically. One end of the slide block 4 extends into the frame 2 and is fixedly connected to the upper mold plate 1. The handle 3 and the frame 2 have the same length extension direction. The handle 3 is set on the upper side of the frame 2, and the other ends of the two slide blocks 4 are respectively fixedly connected to the two ends of the handle 3. Springs 5 ​​are provided in the two slide grooves 2a to make the corresponding slide blocks 4 have an upward movement tendency.

[0030] In actual products, this upper mold structure is used in conjunction with a lower mold, and the lower mold is provided with a punch that matches the mold cavity 1a, and the number of the punches and the mold cavity 1a are the same and their positions correspond one to one.

[0031] When in use, the shoe upper is placed on the punch, and the handle 3 is pressed to make the upper template 1 move downward to overcome the elastic force of the spring 5, so that the punch extends into the mold cavity 1a to hot stamp a pattern on the shoe upper; after the hot stamping is completed, the handle 3 is released, and the upper template 1 moves up and reset under the action of the spring 5, exposing the shoe upper after hot stamping for easy taking.

[0032] With the cooperation of the handle 3, the slider 4, the spring 5 and the upper mold plate 1 with multiple mold cavities 1a, multiple shoe uppers can be hot stamped at one time by pressing the handle 3, which effectively simplifies the operation steps and has the advantages of easy use and high efficiency.

[0033] It is further explained that the upper mold structure also includes a limiting structure for limiting the upward movement distance of the upper mold plate 1 to prevent the upper mold plate 1 from moving upward excessively and affecting subsequent use.

[0034] In this embodiment,

[0035] The limiting structure is specifically as follows: the upper and lower ends of the slide groove 2a are closed, and the limiting structure includes the upper end surface of the slide groove 2a. Under the action of the spring 5, the top surface of the slider 4 can be tightly pressed against the upper end surface of the slide groove 2a to stably limit the upward movement of the upper template 1. It has the advantages of simple structure and stable operation.

[0036] The spring 5 is installed as follows: the lower end surfaces of the two slide grooves 2a are vertically provided with positioning holes 2b matching the spring 5, the lower end of the spring 5 is inserted into the corresponding positioning hole 2b and pressed against the bottom wall of the positioning hole 2b, and the upper end of the spring 5 is pressed against the corresponding slider 4. The above design has the advantages of simple structure and convenient processing while stably positioning the spring 5.

[0037] The connection between the slider 4 and the upper template 1 is as follows: a protrusion 1b is formed on the top surface of both ends of the upper template 1, and the protrusion 1b and the upper template 1 are preferably an integrated structure. The side walls away from the two protrusions 1b are horizontally provided with plug holes, and the adjacent side walls of the two sliders 4 are formed with positioning columns 4a matching the plug holes. The positioning columns 4a and the corresponding sliders 4 are an integrated structure, and the two positioning columns 4a are respectively inserted into the two plug holes to stably connect the slider 4 and the upper template 1 together, which has the advantages of simple structure and convenient assembly.

[0038] The connection method of the handle 3 and the slider 4 is as follows: both ends of the handle 3 are fixedly connected to the two sliders 4 through horizontally arranged screws 6, and the two sliders 4 are located between the heads of the two screws 6.

[0039] like Figure 2 As shown, the upper end of the frame 2 is closed, a cavity 7 is formed between the top wall of the upper template 1 and the inner wall of the frame 2, and a heat dissipation hole 2c connected to the cavity 7 is horizontally penetrated on one of the long side walls of the frame 2, and there are multiple heat dissipation holes 2c. Since the hot stamping process requires the use of a relatively high temperature, the cavity 7 and the heat dissipation holes 2c cooperate to effectively reduce the temperature transfer upward, avoid the operator's hand feeling uncomfortable due to the high temperature, and provide a better user experience.

[0040] Among them, the structure of the frame 2 is as follows: the frame 2 includes a main body of a rectangular cylindrical structure and an insulation board 2d fixed horizontally in the main body. The upper and lower ends of the main body are open, and the heat dissipation holes 2c are arranged on the main body. The insulation board 2d closes the upper port of the main body. The insulation board 2d is provided to further reduce the upward transfer of temperature and make the experience effect better. It is further explained that under the action of the spring 5, the protrusion 1b can be pressed on the insulation board 2d, which can not only enhance the effect of limiting the upward movement distance of the upper template 1, but also enable the protrusion 1b to play the function of limiting the installation position of the insulation board 2d, so that the insulation board 2d can be installed in place at one time, which is convenient for assembly. In actual products, it is preferred that the insulation board 2d is bonded and fixedly connected to the main body. Embodiment 2
