Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.

In the description of the present utility model, it should be understood that if an orientation or positional relationship such as upper, lower, front, rear, left, right, etc. is referred to in the description of the present utility model, it is merely for convenience of description and simplification of the description, and does not indicate or imply that the apparatus or element referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

In the description of the present utility model, a number means one or more, a number means two or more, and greater than, less than, exceeding, etc. are understood to not include the present number, and above, below, within, etc. are understood to include the present number. The description of the first and second is for the purpose of distinguishing between technical features only and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

The utility model will now be further described with reference to examples, figures:

as shown in fig. 1 to 5, an elastic band forming mold comprises an upper mold 2 and a lower mold 3, wherein the lower end of the upper mold 2 is fixedly connected with a U-shaped block a7, the lower mold 3 is provided with a notch 6, the U-shaped block b5 is fixedly connected in the notch 6, the U-shaped block a7 and the U-shaped block b5 are identical in structure and can be matched with each other, and when the elastic band 10 is pressed by being matched with each other, only the outer edge part of the elastic band 10 can be pressed. The total thickness H of the U-shaped block a7 and the U-shaped block b5 is greater than or equal to the distance L from the upper surface of the lower die 3 to the lower end of the U-shaped block b5, otherwise, the U-shaped block b5 may not be pressed at all when the U-shaped block a7 of the upper die 2 is pressed down, so that the process of pressing the rubber band 10 is not completed. The widths d of the U-shaped block a7 and the U-shaped block b5 are 3mm, the requirements on the edges of the rubber strings 10 are very strict, the edges are pressed by 3mm, errors cannot be caused, otherwise, the production of the next working procedure is seriously influenced, and the product quality cannot be guaranteed. The spring 1 is fixedly connected between the upper die 2 and the lower die 3, so that after the pressing of the rubber band 10 is finished, the die can rebound automatically, and the design is more convenient. Grooves are formed in positions corresponding to the positions between the upper die 2 and the lower die 3, and the springs 1 are fixedly connected in the grooves, so that the clamping action is not hindered when the upper die 2 and the lower die 3 are clamped. The upper die 2 and the lower die 3 are internally provided with electric heating parts 9, and the electric heating parts 9 are used for heating and pressing the rubber band 10, so that the pressed rubber band 10 is flatter. As shown in fig. 5, the elastic string 10 is an elastic member of shoelace-free footwear, and can be directly taken off when a user wears or takes off the footwear.

The side of the upper die 2 is provided with a slope 8, and the position of the slope 8 is positioned at the U-shaped opening of the U-shaped block a 7. Since the distance separating the upper and lower molds 3 after the press-fitting of the elastic string 10 is not large, if the exposed portion of the elastic string 10 is not large, it is difficult for the worker to take out the elastic string 10 by hand. However, when the upper die 2 is provided with the slope 8 and the opening of the U-shaped opening is formed, the rubber band 10 can be taken out by hands of a worker through the notch 6 of the lower die 3 and the slope 8 of the upper die 2.

The lower end of the lower die 3 is fixedly connected with a heat insulation block 4. When in heating and pressing, the mold is hot, and the heat insulation block 4 is fixedly connected to the lower end of the lower mold 3, so that heat can be prevented from being transferred to a contact object at the lower end of the lower mold 3.

The number of the springs 1 is at least four, and the springs 1 are uniformly distributed between the upper die 2 and the lower die 3. The number of the springs 1 should be set to ensure the stability of the opening and closing of the upper die 2 and the lower die 3, which may damage the die. When the number of the springs 1 is four, the springs 1 are distributed at four corners between the upper die 2 and the lower die 3, so that the stability of the opening and closing of the upper die 2 and the lower die 3 can be ensured.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
