Description

Technical Field

[0001] The utility model relates to the field of material molding, in particular to a soft package material molding jig. Background Art

[0002] In various industrial fields, especially in the automotive, aviation and household appliance manufacturing industries, the hot pressing technology of soft-pack materials is widely used for surface coating of various structural parts. This technology heats the soft-pack material to a certain temperature, uses a mold to press it into shape, and then coats it on the surface of the structural part to achieve the purpose of aesthetics, protection and / or enhanced structural strength. However, when the existing molding jig faces structural parts with deep concave surfaces, the soft-pack material needs to be stretched to a larger deformation, and the tensile force on the material increases, resulting in a significantly increased risk of rupture. In addition, the stress concentrated on the edge of the concave surface of the material can also cause rupture problems. Utility Model Content

[0014] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The utility model provides a soft-pack material forming jig, comprising a bottom die 1 and an upper die 2, wherein a forming cavity 11 is provided at the upper portion of the bottom die 1, and a pressing die 21 is provided at the lower portion of the upper die 2, wherein the pressing die 21 corresponds to the forming cavity 11, and is used for placing a soft-pack sheet between the bottom die 1 and the pressing die 2 during forming, and embedding the soft-pack sheet into the forming cavity 11 through the movement of the pressing die 21 to complete the forming, and further comprising a spring plate 3 arranged between the bottom die 1 and the upper die 2, wherein the spring plate 3 is provided with an avoidance opening 31 for the pressing die 21 to pass through.

[0016] The soft-pack material forming jig provided by the utility model is applied to a hot pressing device, which is a commonly used device in industrial production and is not limited here. The movable end of the hot pressing device is fixed to the upper mold 2 to provide the temperature and pressure for hot pressing forming. In the embodiment, the problem of easy rupture when forming a deeper concave surface is solved. In the specific processing process, the soft-pack sheet is placed above the molding cavity 11 of the lower mold 1, and the spring plate 3 first contacts the soft-pack sheet. Then the hot pressing device drives the die 21 of the upper mold 2 to be embedded in the molding cavity 11 to complete the molding. In the process of the die 21 being embedded in the molding cavity, not only the soft-pack sheet located at the mouth of the molding cavity 11 is deformed, At the same time, other parts of the soft-pack sheet will also be pushed into the molding cavity 11, so as to reduce the requirements for deformation. It can be understood that if other parts of the soft-pack sheet are pushed into the molding cavity 11 too much, wrinkles will be generated at the mouth of the molding cavity 11, and the molding effect will be poor, and it will be easy to rebound after demolding. If other parts of the soft-pack sheet are pushed into the molding cavity 11 too little, the deformation will be too large and the soft-pack material will be easily damaged. In this embodiment, the spring plate 3 is used to press the soft-pack sheet. By adjusting the degree of compression, the amount of soft-pack material pushed into the molding cavity 11 can be controlled, which can not only ensure the molding effect but also avoid damage to the soft-pack material.

[0017] In one embodiment, a specific installation scheme of the spring plate 3 is provided to facilitate adjusting the degree of compression of the spring plate 3 on the soft package sheet. First mounting plates 22 are respectively installed on the opposite sides of the upper mold 2, and second mounting plates 32 are respectively installed on the opposite sides of the spring plate. A pressure rod 33 is installed above the second mounting plate 32. A through hole is opened at the position corresponding to the first mounting plate 22 and the pressure rod 33. The pressure rod 33 passes through the through hole and is slidably connected to the first mounting plate 22. A mounting tube 23 is provided above the first mounting plate 22 at the position of the through hole. A mounting cavity is provided in the mounting tube 23. The mounting cavity 23 is aligned with the through hole. A spring is installed in the mounting cavity. The top of the pressure rod 33 passes through the through hole into the mounting cavity and contacts with the spring.

[0018] It can be understood that because the utility model is to form a soft-pack material with a deeper concave surface, the height of the die 21 is relatively high. Similarly, the height of the mounting cylinder 23 is also relatively high. In this embodiment, the position of the mounting cylinder 23 can be adjusted by the first mounting plate 22 and the second mounting plate 32 to avoid interference of the mounting cylinder 23 when the upper mold 2 is installed in the hot pressing equipment; during the processing, the upper mold 2 moves downward, and the deformation spring plate 3 of the spring can apply pressure to the soft-pack material.

[0019] In one embodiment, to facilitate the processing of the mounting tube 23, the mounting tube 23 includes a first fixing plate 231 and a second fixing plate 232, and the first fixing plate 231 and the second fixing plate 232 are respectively provided with a first mounting groove 2311 and a second mounting groove on opposite sides thereof, and the first mounting groove 2311 and the second mounting groove constitute a mounting cavity, and a cover plate 233 is installed above the first fixing plate 231 and the second fixing plate 232.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
