Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figures 1 to 8 This utility model provides a specific technical implementation scheme for the structure of a mask mold:

[0029] Specifically, the mask mold fixing mechanism consists of a lower template 2 fixedly mounted on a lower mold fixing plate 1, and a lower mold base 3 fixedly mounted above the lower template 2. A slot for mounting a ejector plate 4 is provided in the middle of the lower mold base 3. The ejector plate 4 is slidably mounted in the slot. A groove for limiting the ejector plate 4 is provided on the lower template 2 to prevent the ejector plate 4 from detaching from the lower template 2 during sliding. The slots on the lower mold fixing plate 1 and the lower template 2 connect the ejector plate 4 to the ejector mechanism.

[0030] Specifically, the demolding mechanism and demolding method of the mask mold are fixedly set on the top side of the ejector plate 4 by the pin 5; the lower mold 6 is fixedly set on the lower mold base 3, and the lower mold 6 is slidably connected to the pin 5.

[0031] The ejector plate 4 pushes the pin 5 up and down, and the sliding of the pin 5 can push the mold core 7 upward, making it easier to demold.

[0032] Specifically, the mold core mechanism of the face mask mold and its role and advantages in the face mask forming process:

[0033] The mold core 7 includes a mask part 71, a guide part 72, a slider 73 and a connecting part 74. The mask part 71 is slidably disposed on the lower mold 6 and is inserted into the pin 5. The guide part 72 is slidably disposed on both sides of the mask part 71 and is inserted into the pin 5.

[0034] This split design makes it easy to remove the mask part 71 and the guide tube part 72 located inside the mask after the mask is formed, thus obtaining the finished mask, which is convenient to operate.

[0035] The slider 73 is slidably mounted on the lower mold 6. The lower mold 6 has a groove 601 for mounting the slider 73, and a slide rail 602 is provided in the groove 601. The slider 73 is slidably connected to the groove 601 and the slide rail 602.

[0036] Both the slide groove 601 and the slide rail 602 limit the slider 73 to prevent it from tilting and ensure the accuracy of the mask mold during the mold closing process.

[0037] The connecting part 74 in the mold core 7 is fixedly mounted on the slider 73. The connecting groove 1201 is opened on the lower mold 6 and the connecting part 74. When the connecting part 74 abuts against the lower mold 6, the connecting groove 1201 on the connecting part 74 and the connecting groove 1201 on the lower mold 6 are spliced ​​together to form a connecting hole 12. By setting the connecting hole 12, the forming space of the mask part 71 and the guide tube part 72 is connected.

[0038] During molding, the connecting hole 12 is filled with raw material. After the mask is molded, a connecting rod will be formed at the connecting hole 12, so that the mask and the guide tube are connected by the connecting rod, which improves the overall firmness of the mask.

[0039] Two sliders 73 are provided on the lower mold 6, and the two sliders 73 are symmetrically arranged. The connecting parts 74 on the two sliders 73 pass through the lower part of the guide tube 72 and abut against each other. The connecting parts 74 and the guide tube 72 are spaced apart. When the connecting parts 74 on the two sliders 73 abut against each other, they are located below the guide tube 72, closing the lower part of the guide tube 72, thereby forming the forming space of the mask guide tube. The mold is opened by sliding, which makes it easy to take out the finished product and facilitates operation.

[0040] Methods for controlling displacement during mold closing in mask molds:

[0041] The upper mold 8 is located above the lower mold 6, and the pressure plate 9 is fixedly installed on the bottom side of both ends of the upper mold 8. The pressure plate 9 is slidably connected to the lower mold 6, and the pressure plate 9 abuts against the slider 73. The pressure plate 9 is located on the side of the slider 73 away from the connecting part 74, and the bottom of the pressure plate 9 is provided with a groove for accommodating the slide rail 602. The outer wall of the slider 73 away from the connecting part 74 is inclined, and the distance between the outer wall of the slider 73 away from the connecting part 74 and the connecting part 74 gradually increases from top to bottom. When the pressure plate 9 descends, it pushes the two sliders 73 on the lower mold 6 inward under the action of the inclined surface to complete the mold closing, preventing the sliders 73 from moving during the molding process.

[0042] The upper mold fixing plate 11 is fixedly installed on the top side of the upper template 10 to fix the upper template 10. The upper template 10 is fixedly installed on the top side of the upper mold 8. The upper mold 8 is moved by the upper mold fixing plate 11 to realize the mold opening and closing.

[0043] Specific implementation steps:

[0044] When the mold is closed, the upper mold fixing plate 11 pushes the upper mold 8 down. When the pressure plate 9 descends, it pushes the two sliders 73 on the lower mold 6 inward under the action of the inclined surface to complete the mold closing. The raw material is injected into the mold through the injection port on the upper mold fixing plate 11. After cooling, the mold is opened. When the mold is opened, the pressure plate 9 rises, the two sliders 73 slide outward, the ejector plate 4 pushes upward to eject the mold core 7, and the finished mask is removed. The mask part 71 and the guide tube part 72 are removed from the finished mask in sequence, and then the mask part 71 and the guide tube part 72 are put back into the lower mold 6.

[0045] In summary, this mask mold structure features a slider slidably mounted on the lower mold, with a pressure plate abutting against the slider. The outer wall of the slider, away from the connecting part, is inclined. When the pressure plate descends, the inclined surface pushes the two sliders on the lower mold inward to close the mold, preventing movement of the sliders during molding. The connecting part is fixedly mounted on the slider, and when the two connecting parts on the sliders abut, they are located below the guide tube, sealing the lower part of the guide tube and forming the molding space for the mask guide tube. The sliding mold opening method facilitates the removal of the finished product and is convenient to operate. The mask part is slidably mounted on the lower mold and connected to a pin. The guide tube is slidably mounted on both sides of the mask part and connected to pins. The design features a split structure, facilitating the removal of the mask section and guide tube section after the mask is formed, thus simplifying demolding and operation. The mask is constructed by connecting slots formed by connecting holes. These connecting slots are located on the lower mold and the connecting part. When the connecting part abuts against the lower mold, the connecting slots on the connecting part and the connecting slots on the lower mold connect to form connecting holes. These connecting holes connect the forming spaces of the mask section and the guide tube section, creating a connecting rod between the two parts after the mask is formed, improving the overall robustness of the mask. This improvement in the mask mold structure results in a rational design, facilitating mold closing and opening, demolding, and operation, while also enhancing the overall robustness of the mask and its practicality. This effectively solves the problems and shortcomings of existing technologies and equipment.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
