Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cup-shaped masks, and in particular to a cup-shaped mask shaping mold. Background Technology
[0002] Cup-shaped masks are a common type of protective mask, named for their cup-like shape. They cover the user's mouth, nose, and other facial areas, effectively preventing airborne pollutants from entering the respiratory tract. Compared to flat masks, the unique shape of cup-shaped masks provides a better seal against the face, making it less likely for dust and viruses to leak in. Additionally, the ergonomic nose design with a built-in soft foam nose pad increases wearing comfort.
[0003] Cup-shaped masks typically consist of an outer layer, a pre-filter layer, a core filter layer, a shaped cup layer, and an inner layer. During the production process, the hot air cotton is usually preheated and softened first, and then molded into a shaped cup layer. Then, the materials of other layers are stacked on the shaped cup layer, and then the edges are welded using ultrasonic welding to fix the connection between the layers. Finally, the edges are cut off using a punching mechanism.
[0004] In the production process of cup-shaped masks, when workers stack other layers of material onto the shaped cup layer and then use ultrasonic welding to weld the edges, they also need to place the other layers of material and the shaped cup layer into a shaping mold for shaping.
[0005] Existing molding dies typically consist of an upper mold and a lower mold. The lower mold has a forming groove, and the other layers of material and the molding cup layer are placed in the forming groove of the lower mold. The upper mold is then used to press and shape them. However, observations have shown that during the pressing and shaping process, the other layers of material are very prone to wrinkling, resulting in an extremely high defect rate.
[0006] In view of this, the designer has deeply conceived and actively researched and improved the design of this utility model, addressing the numerous shortcomings and inconveniences caused by the imperfections in the production process of the aforementioned cup-shaped masks. Utility Model Content
[0007] The purpose of this invention is to provide a cup-shaped mask shaping mold.
[0008] To achieve the above objectives, the solution of this utility model is: A cup-shaped mask shaping mold includes a lower mold with a forming groove. The inner wall of the forming groove has two protrusions located on the same side and on the side of the cup-shaped mask nose bridge shape, and there is an avoidance space between the two protrusions.
[0009] Preferably, the outer surfaces of the two protrusions are provided with a shaping part that conforms to the shape of the human nose bridge.
[0010] Preferably, the lower mold is provided with a punching cutter holder at the opening of the forming groove; the shaping mold also includes a punching pad and a punching cutter head; the punching pad is sleeved on the punching cutter holder, and the punching cutter head moves back and forth to the punching cutter holder under the control of the driving mechanism.
[0011] By adopting the above solution, this utility model provides two protrusions on the inner wall of the forming groove. When the other layers of material and the shaping cup are placed in the forming groove, the two protrusions limit the other layers of material, leaving a gap between the other layers of material and the inner wall of the forming groove. Therefore, the other layers of material will not be squeezed and wrinkled in the forming groove. When the upper mold presses and shapes them, they can be formed neatly, which has the advantage of high yield. Attached Figure Description

[0015] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0016] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0017] like Figures 1 to 2 As shown, this is a preferred embodiment of a cup-shaped mask shaping mold of the present invention. The shaping mold includes a lower mold 1, on which a forming groove 11 is provided. Two protrusions 12 are provided on the inner wall of the forming groove 11. The two protrusions 12 are located on the same side and on the side of the cup-shaped mask nose bridge shape, and an avoidance space 13 is provided between the two protrusions 12.
[0018] The key feature of this invention is that, by providing two protrusions 12 on the inner wall of the forming groove 11, when other layers of material and the shaping cup are placed in the forming groove 11, the two protrusions 12 limit the other layers of material, leaving a gap between the other layers of material and the inner wall of the forming groove 11. Therefore, the other layers of material will not be squeezed and wrinkled in the forming groove 11. When the upper mold presses and shapes them, they can be formed neatly, resulting in a high yield rate.
[0019] The two protrusions 12 mentioned above have a shaping part on the outside that conforms to the shape of the human nose bridge. In this way, the two protrusions 12 can better cooperate with the compression and shaping of the cup-shaped mask, so that the cup-shaped mask is formed into a shaping part that conforms to the shape of the human nose bridge.
[0020] The lower mold 1 is provided with a punching cutter holder 14 at the opening of the forming groove 11; the shaping mold also includes a punching pad 2 and a punching cutter head 3; the punching pad 2 is sleeved on the punching cutter holder 14, and the punching cutter head 3 moves back and forth on the punching cutter holder 14 under the control of the drive mechanism. In this way, when other layers of material and the shaping cup are placed in the forming groove 11, the punching pad 2 can be used to press the other layers of material and the shaping cup onto the lower mold 1. The pressure of the punching pad 2 makes the other layers of material and the shaping cup more spread out, so that the other layers of material will not be squeezed and wrinkled in the forming groove 11. When the upper mold presses and shapes them, they can be formed neatly, which has the advantage of high yield rate; and after pressing and shaping, the scrap material of the cup-shaped mask can be cut off by the cooperation of the punching cutter head 3 and the punching cutter holder 14 in the control box of the drive mechanism, which has the advantage of convenient production and processing.
[0021] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments and various choices and variations of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
