[0030] The embodiment of the present utility model provides a forming die of a breathing mask, as shown in Figures 3-10 The forming die comprises:

[0031] The upper die assembly 100 comprises an upper die core 110 for forming a lower surface 10 of the breathing mask and an upper die insert 120 for forming a breathing hole 11, and the upper die insert 120 is connected to the upper die core 110;

[0032] The lower mold assembly 200 includes a lower mold core 210 for forming the upper surface 12 of the breathing mask, a lower mold insert 220 for forming the tube hole 13, and a slider assembly 230. The lower mold core 210 is connected to the lower mold insert 220, and the slider assembly 230 is in sliding cooperation with the lower mold core 210. The slider assembly 230 includes two first sliders 231 for forming the first support 14 and two second sliders 235 for forming the second support 15, which are respectively arranged on both sides of the lower mold core 210.

[0033] The upper mold assembly 100 includes an upper mold core 110 for forming the lower surface 10 of the breathing mask and an upper mold insert 120 for forming the breathing hole 11. The upper mold insert 120 is connected to the upper mold core 110 and moves simultaneously with the upper mold core 110.

[0034] The lower mold assembly 200 includes a lower mold core 210 for forming the upper surface 12 of the breathing mask and a lower mold insert 220 for forming the tube hole 13. The lower mold insert 220 is connected to the lower mold core 210. The slider assembly 230 includes two first sliders 231 for forming the first support 14 and two second sliders 235 for forming the second support 15. The slider assembly 230 is in sliding cooperation with the lower mold core 210, and the sliders can move within the lower mold core 210 to achieve demolding of the first support 14 and the second support 15. The slider assembly 230 is used for forming the support structure, which can achieve complex structure forming and improve the forming precision and efficiency of the mold. The upper mold insert 120 and the lower mold insert 220 are respectively used for forming the breathing hole 11 and the tube hole 13, which can facilitate the maintenance and replacement of the mold and improve the versatility of the mold.

[0035] In some embodiments, the lower mold core 210 is provided with a first forming part 211 for forming the first support 14, which includes protruding parts 212 arranged on both sides for forming the connecting holes 16. The protruding parts 212 are provided with grooves 213, and the first sliders 231 include plug-in blocks 232 for forming the flat grooves 17 and the circular arc grooves 18, which are connected in cooperation with the grooves 213.

[0036] The first forming part 211 is a part of the lower die core 210 for forming the first support 14. The first forming part 211 is provided with a protruding part 212 on both sides for forming the connecting hole 16, and the protruding part 212 is further provided with a groove 213. The purpose of these designs is to cooperate with the plug-in block 232 of the first slider 231 to achieve accurate molding of the mold. The first slider 231 has a plug-in block 232 for forming the flat groove 17 and the circular arc groove 18. The plug-in block 232 of the first slider 231 is connected with the groove 213 on the protruding part 212 of the lower die core 210, which ensures that the slider can accurately dock with the lower die core 210 during movement, thereby realizing complex molding structure. Through the cooperation of the protruding part 212 and the groove 213, and the accurate docking of the plug-in block 232, the forming accuracy of the first support 14 can be ensured.

[0037] Further, the plug-in block 232 includes a square block 233 for forming the flat groove 17 and a circular arc block 234 for forming the circular arc groove 18.

[0038] Through the split design of the square block 233 and the circular arc block 234, the flat groove 17 and the circular arc groove 18 can be accurately formed respectively, ensuring the structural accuracy of the first support 14.

[0039] In some embodiments, the lower die core 210 is further provided with a second forming part 214 for forming the second support 15, and the second forming part 214 is provided with a first support groove 215. The second slider 235 is provided with a second support groove 236, and the first support groove 215 and the second support groove 236 are combined to form the second support 15.

[0040] The first support groove 215 is arranged on the second forming part 214 of the lower die core 210 for forming a part of the second support 15. Its shape and size are matched with the design requirements of the second support 15 to ensure the forming accuracy. The second support groove 236 is arranged on the second slider 235 for forming another part of the second support 15. The second slider 235 is combined with the second forming part 214 of the lower die core 210 through sliding fit, so that the first support groove 215 and the second support groove 236 can be closely matched to form a complete second support 15. This split design can complete the forming of complex support structure, and is convenient for disassembly and maintenance of the mold.

[0041] In some embodiments, the lower end of the upper die insert 120 is provided with a protruding point 121 for forming the breathing hole 11.

[0042] The shape and size of the convex points 121 are adjusted according to the design requirements of the breathing hole 11, which can be circular, oval or other suitable shapes, to ensure the accurate molding of the breathing hole 11. The convex points 121 are arranged at intervals to meet the distribution requirements of the breathing hole 11 on the respiratory mask. These convex points 121 cooperate with the lower mold assembly 200 when the mold is closed, forming the breathing hole 11 on the respiratory mask to provide a comfortable breathing passage for the user.

[0043] In some embodiments, the upper mold core 110 is provided with a pipe hole groove 111 cooperating with the lower mold insert 220.

[0044] The shape and size of the pipe hole groove 111 match the pipe hole 13 molding part of the lower mold insert 220, ensuring that the pipe hole 13 structure of the respiratory mask can be accurately molded when the mold is closed.

[0045] Further, the lower mold insert 220 includes a first circular table 221 and a second circular table 222 arranged from bottom to top.

[0046] The first circular table 221 is located at the bottom of the lower mold insert 220 and is mainly used for support and positioning. It has a larger size to provide a stable base for the entire lower mold insert 220 and closely cooperates with the lower mold core 210 to ensure accuracy and stability during molding. The second circular table 222 is located above the first circular table 221 and has a smaller diameter than the first circular table 221, forming a stepped structure. By designing the stepped structure, the mold can be easily opened.

[0047] Further, the diameter of the second circular table 222 is smaller than the diameter of the first circular table 221.

[0048] The stepped structure formed by the difference in diameter can better position and cooperate with the pipe hole groove 111 of the upper mold core 110, ensuring the accurate molding of the pipe hole 13.
