Technical Field

[0001] The utility model relates to the technical field of button production equipment, in particular to a button production mold. Background Art

[0002] In ancient Rome, buttons were originally used for decoration, while brooches were used to fasten clothes. It wasn't until the 13th century that buttons began to function as they do today. By then, people had already mastered the art of making buttonholes, a practice that greatly enhanced the practical value of buttons. Buttons became increasingly popular in the 16th century. With the rise of fast fashion, buttons have evolved from being functional to being creative, becoming a decorative accessory.

[0003] Plastic buttons currently on the market are generally made by hot-melting plastic and pouring it into a mold. This process requires a significant amount of manpower to demould the buttons. This involves manual demoulding, which requires workers to remove the buttons one by one and then collect them. Manual demoulding can also easily cause scratches on the buttons, affecting the quality of the finished product. Furthermore, large production volumes require more manpower and time, significantly hindering a company's production and development. Utility Model Content

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example: As shown in the attached Figures 1 to 10 The button production mold shown in the figure includes a base 1, a pressure seat 2, a lower template 3 and an upper template 4. The lower template 3 and the upper template 4 are respectively arranged on the base 1 and the pressure seat 2. When the upper template 4 is pressed on the lower template 3, an injection channel 5 and a plurality of mold cavities 6 connected to the injection channel 5 are formed between the upper template 4 and the lower template 3. In this embodiment, the injection channel 5 and the mold cavity 6 can both be composed of two parts, wherein the injection channel 5 is composed of an upper runner groove on the upper template 4 and a lower runner groove on the lower template 3, and the mold cavity 6 is composed of an upper mold groove on the upper template 4 and a lower mold groove on the lower template 3. The upper template 4 is provided with an injection hole 7 connected to the injection channel 5, and the base 1 is also provided with a demolding seat 8 that is vertically movably provided. A plurality of first ejectors 9 and a plurality of second ejectors 10 are installed on the demolding seat 8. The bottom of the lower template 3 is provided with a plurality of first through holes 11 connected to the injection channel 5 and a plurality of second through holes 12 connected to the mold cavity 6. The first ejectors 9 are inserted into the corresponding first through holes 11, and the second ejectors 10 are inserted into the corresponding second through holes 12. In this embodiment, each finished button is ejected by two second ejectors 10. When producing buttons, the upper template 4 is pressed onto the lower template 3, and the injection molding raw material is injected from the injection hole of the upper template 4. The injection molding raw material flows into the mold cavity 6 through the injection channel 5 and fills the mold cavity 6. After the injection molding is completed, the upper template 4 is separated from the lower template 3, and the demolding seat 8 drives the first ejector 9 and the second ejector 10 upward to eject the remaining material in the injection channel 5 and the finished button in the mold cavity 6 to achieve demolding. Subsequently, it is only necessary to separate the finished button from the remaining material, which is very convenient. The mold can realize the injection molding and automatic demolding of large quantities of buttons, achieve high-quality and high-efficiency production of buttons, and can bring good economic benefits to the enterprise.

[0038] As attached Figure 3 、 4 As shown, the injection channel 5 includes a main channel 13, a plurality of first branch channels 14 connected to the main channel 13, and a plurality of second branch channels 15 connected to the first branch channels 14. Each second branch channel 15 is connected to the bottom end of the corresponding mold cavity 6 through an injection channel 16. In this embodiment, the plurality of first branch channels 14 are evenly arranged on both sides of the main channel 13, and the plurality of second branch channels 15 are evenly arranged on both sides of the corresponding first branch channels 14. The plurality of branch channels divided from the main channel 13 can greatly increase the number of buttons that can be injected, and the second branch channels 15 (end channels) are connected to the bottom end of the corresponding mold cavity 6 through the injection channel 16. During demolding, the remaining material is connected to the back of the finished button. During separation, even if the back of the finished button is uneven, it will not affect the aesthetics of its front and side surfaces.

[0039] As attached Figure 7As shown, the cross-sectional area of ​​the injection flow channel 16 gradually decreases in the direction close to the mold cavity 6. This design makes the connection between the remaining material and the button product thinner after demoulding, making it easier to separate the two later. At the same time, the cross-section of the back of the button product is also smaller.

[0040] As attached Figure 7 As shown, the injection flow channel 16 is in a shape with a low middle and high ends. Its shape can be U-shaped or V-shaped, so as to achieve injection from the bottom of the mold cavity 6.

A portion of the mold cavity 6 is provided between the upper mold plate 4 and the lower mold plate 3, and another portion of the mold cavity 6 is provided between the upper mold plate 4 and the runner module 18. Modularizing the injection molding structure not only facilitates mold assembly but also enables mass injection molding production of buttons.

[0042] As attached Figures 7-9 As shown, the runner module 18 includes a plurality of runner modules 19 arranged side by side, and the runner modules 19 are detachably connected to the mounting slots 17 by fasteners (which may be screws). An injection molding runner 16 is formed between each two adjacent runner modules 19. For example, one runner module 19 has a left slot on its side, and the adjacent runner module 19 has a right slot. When the two runner modules 19 are joined, the left and right slots form an injection molding runner 16. Since the injection molding runner 16 has a special-shaped structure, the runner module 18 is divided into multiple runner modules 19, and the injection molding runner 16 is arranged between two runner modules 19, which is more conducive to the processing of the injection molding runner 16.

[0043] As attached Figure 3 As shown, the first branch flow channels 14 are connected end to end in a group of two to form a closed loop channel. This design can make the injection molding of raw materials more uniform and ensure the quality of button injection molding.

[0044] As attached Figure 6As shown, the demolding base 8 includes an upper positioning plate 20 and a lower positioning plate 21, which are detachably connected together by screws. A plurality of first positioning holes 22 and second positioning holes 23 with inverted T-shaped cross-sections are vertically provided on the upper positioning plate 20. The bottom end of the first ejector pin 9 is shaped to match the shape of the first positioning hole 22 and is disposed within the first positioning hole 22. The bottom end of the second ejector pin 10 is shaped to match the shape of the second positioning hole 23 and is disposed within the second positioning hole 23. This design enables the positioning and installation of the first and second ejector pins 9, 10, and the installation structure is simple and reliable, making assembly and disassembly very convenient.

[0045] As attached Figure 10 As shown, the base 1 is vertically mounted with a plurality of first guide posts 24, the demolding base 8 is provided with a plurality of first guide sleeves 25 that cooperate with the first guide posts 24, the upper mold plate 4 is vertically mounted with a plurality of second guide posts 26, and the lower mold plate 3 is provided with a plurality of second guide sleeves 27 that cooperate with the second guide posts 26. This design guides the demolding base 8 and the upper mold plate 4, making their vertical movement more stable.

[0046] As attached Figure 1 As shown, the lower mold plate 3 is provided with a plurality of positioning protrusions 28, which can be mounted on the lower mold plate 3 by screws. The upper mold plate 4 is provided with a plurality of positioning recesses 29 that fit with the positioning protrusions 28, which can be mounted on the upper mold plate 4 by screws. When the upper mold plate 4 and the lower mold plate 3 are mated, they can be positioned, ensuring accurate mating between them while maintaining structural stability and preventing displacement during the injection molding process.
