[0038] Example

[0039] Reference Fig. 9 In the flying disc 80 shown, the inner side wall of the groove of the flying disc 80 is inclined toward the bottom to form a full circle of undercut.

[0040] Reference Figure 1-3As shown, the utility model discloses a forming mold for a flying disc, including a panel 10, an upper pad 20, a lower pad 30, an upper movable mold 40, a mold core, a lower fixed mold 60, and a bottom plate 70 from top to bottom. The mold core includes a core 50 installed on the lower pad 30, a sleeve ring 52 installed on the upper movable mold 40, and a lower mold core 53 installed on the lower fixed mold 60. The core 50, the sleeve ring 52 and the lower mold core 53 can form a cavity; specifically, the core 50 has a through hole, the panel 10 is provided with a glue hot nozzle, and the glue hot nozzle extends from the through hole to the cavity. When the mold is closed, hot melt glue is delivered to the cavity through the glue hot nozzle to form a flying disc 80. Furthermore, the panel 10 is provided with a guide column, which passes through the upper pad 20, the lower pad 30, the upper movable mold 40 to the lower fixed mold 60 from top to bottom in sequence. The guide column can prevent the upper pad 20, the lower pad 30, the upper movable mold 40, and the lower fixed mold 60 from being neatly unified when the mold is closed, and avoid gaps caused by improper mold closing, which leads to burrs on the product.

[0041] Reference Figure 3-7 As shown, a stepped air hole 503 penetrating the upper and lower end surfaces is provided in the core 50, and a plurality of connecting holes are provided on the end surface of the lower pad 30 facing the upper movable mold 40. The connecting holes are connected to the upper end of the air hole 503, and the other end of the connecting holes extends to the outside. The external air source enters the air hole 503 from the connecting holes to inflate the air hole 503. A plurality of air push mechanisms 51 are provided at one end of the air hole 503 close to the lower mold core 53. The push mechanisms are arranged circumferentially around the hot glue nozzle. The air push mechanisms 51 include 4 to 6. In this embodiment, the air push mechanisms 51 include 4. The air push mechanisms 51 include a sleeve 511 and a push rod 512. The sleeve 511 is symmetrically provided with two guide grooves 5111 along the length direction. The push rod 512 includes a push head 5121, a connecting rod and a guide rod 5122. The push head 5121 is fixed to one end of the connecting rod, and the guide rod 5122 vertically passes through the other end of the connecting rod. The guide rod 5122 is placed in the guide groove 5111. Specifically, the sleeve 511 is fixed to the air hole 503, and the push rod 512 is slidably placed in the sleeve 511. When the mold is closed and injection molding is performed, the push head 5121 blocks the sleeve 511 to prevent the hot melt adhesive from entering the sleeve 511 to the air hole 503. After the flying disc 80 is formed in the cavity, the gas enters from the air hole 503 to push the push head 5121 to move from the sleeve 511 to the cavity. The push head 5121 pushes out and the gas enters between the core 50 and the flying disc 80. When the air pressure reaches a certain value, the flying disc 80 is pushed off from the core 50. At this time, the guide rod 5122 is stuck in the guide groove 5111 to prevent the push rod 512 from flying out as a whole. The utility model realizes the demoulding of the flying disc 80, and avoids the use of ejector pins or push blocks to push out the flying disc 80, which causes the flying disc 80 to be broken or marked, thereby affecting the overall appearance.

[0042] Reference Figure 6-7As shown, the core 50 includes an upper core 501 and a lower core 502, wherein the lower core 502 has an annular first cooling groove 5021 on its end surface close to the upper core 501. The combination of the upper core 501 and the lower core 502 facilitates assembly, and a coolant is passed through the annular first cooling groove 5021, so that the cooling is uniform during mold closing and injection molding, and the cooling speed is fast, resulting in a good effect.

[0043] Reference Figure 8 As shown, the lower mold core 53 is provided with a molding groove, and an overflowing glue groove is arranged around the molding groove. When the mold is closed for injection molding, the overflowing glue groove can accommodate the excess hot melt glue overflowing from the cavity. Furthermore, the lower mold core 53 is provided with a plurality of annular second cooling grooves 531 at the bottom of the molding groove to further improve the cooling efficiency and cooling effect.

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
