Description of the Related Art Conventionally, when a nonwoven fabric is fused to a resin ring, the resin ring is molded, the nonwoven fabric is cut into a desired shape, and then the nonwoven fabric is fused to the resin ring. However, the molding method requires a lot of molding time and equipment, and an increase in product cost cannot be avoided.

Therefore, conventionally, a die for cutting a non-woven fabric, an injection die for forming a ring, a fusing jig for fusing a non-woven fabric to a ring, etc. have been required, and the number of required facilities and the number of working steps have been large.

インジェクション成型用金型を得たものがある。SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks of the prior art, the present invention provides a fixed die portion of a die and a separation line portion of a movable die portion with a blade shape formed of a punch and a die. Injection molding that can be integrally molded by cutting the nonwoven fabric inserted into the mold into the required shape at the same time as clamping the mold, injecting synthetic resin into the cutting location at the same time, and fusing with the peripheral part of the nonwoven fabric. There is one that got the mold.

その周囲に合成樹脂を注入して融着するので、金型が一
つですみ作業工程も大巾に削減される。In the present invention, one die is used to cut the nonwoven fabric,
Since synthetic resin is injected and fused around it, only one mold is required and the work process is greatly reduced.

た樹脂で固めてしまうので、従来のものより強くなる。Conventionally, a press die for cutting a non-woven fabric, an injection die for forming a resin ring for attaching the non-woven fabric, a fusion jig and the like are required. Therefore, in the present invention, the number of required dies and the number of working steps are required. However, the fusion strength is stronger than the conventional one because the fusion bonding strength is fixed by the resin injected around the periphery of the nonwoven fabric.
