[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Example

[0029] A mold for a mobile phone box packaging liner includes an upper mold 10 and a lower mold 20. The upper mold 10 is provided with an upper template 11, and the lower mold 20 is provided with a lower template 21. The upper template 11 and the lower template 21 are fitted together to form a cavity 30. The upper template 11 is provided with a first boss 12, and the first boss 12 extends downward to the lower template 21 to provide a second boss 13. The first boss 12 and the second boss 13 are connected by a step 14. The bottom surface of the second boss 13 is located at the center of the first boss 12, and its area is smaller than the top surface of the first boss 12. The lower template 21 is provided with a cavity 22 adapted to the first boss 12 and the second boss 13. The upper mold 10 and the lower mold 20 are connected to a heating device. The heating device is preferably an energized resistance wire that is evenly distributed and attached to the upper mold 10 and the lower mold 20.

[0030] The upper template 11 has third protrusions 15 on both sides of the outer periphery of the cavity 30. The third protrusions 15 are used to accommodate the buttons on the side of the mobile phone. Optionally, the third protrusions 15 are symmetrically arranged on both sides of the cavity to accommodate mobile phones with buttons on the left and right sides. A fourth protrusion 16 is also provided on the edge of the second protrusion 13. The fourth protrusion 16 passes through the step 14 and is set at the same height as the second protrusion 13.

[0031] Both the upper mold 10 and the lower mold 20 are provided with positioning holes 31. The outer edge of the upper mold 10 is provided with a protrusion 32, and the outer edge of the lower mold 20 is provided with a recess 33 that matches the protrusion 32. The protrusion 32 and the recess 33 are fitted with a clearance. A separation cavity 34 is also provided between the positioning holes 31 of the upper mold 10 and the lower mold 20.

[0032] To improve the flatness of the liner surface and make its appearance smoother, the technical solution provided by this utility model further includes: a first air extraction hole 35 is provided at the edge of the upper template 11 and the lower template 21, respectively, passing through the upper mold 10 and the lower mold 20 and connecting to the cavity 30; a second air extraction hole 36 and a third air extraction hole 37 are respectively opened at the center of the upper mold 10 and the lower mold 20. For the product, these are split holes used to separate the liner from the phone box. The user can insert their finger into the split hole and then bend their finger to pull the liner to separate it. The second air extraction hole 36 and the third air extraction hole 37 are staggered, and the first, second, and third air extraction holes are all connected to a vacuum device.

[0033] Working principle:

[0034] First, the wet pulp blank is placed into the lower mold 20. Then, the upper mold 10 and lower mold 20 are precisely positioned and closed through the cooperation of the positioning holes 31, protrusions 32, and recesses 33. When the upper mold 10 and lower mold 20 are closed, the cavity 30 is formed, and the wet pulp blank is located inside the cavity 30 for forming the liner of the mobile phone box packaging. The mold can be connected to a hydraulic press or other devices to increase the mold closing pressure. Preferably, a heating device transfers heat to the upper mold 10 and lower mold 20, raising the mold temperature. This accelerates the evaporation of moisture in the wet pulp blank, which is beneficial for molding.

[0035] During the molding process, the first boss 12, the second boss 13, the third boss 15, and the fourth boss 16 respectively mate with the cavity 22 on the lower template 21. The cavity formed by the second boss 13 is used to house the portion of the phone's back panel protruding from the camera lens. The height of the second boss 13 is preferably not less than 2mm and not more than 3mm, accommodating most commercially available phone types. Because the area of ​​the second boss 13 is large, no modifications are needed for the camera position of each phone model. For the same purpose, the third boss 15 is used to accommodate buttons that may be present on the side of the phone, and its length is preferably not less than 3cm. The fourth boss 16 passes through the step 14 and is set at the same height as the second boss 13, serving a supporting and positioning function. It also acts as a reinforcing rib, better distributing the central load and improving the strength of the wet pulp packaging liner.

[0036] To improve the flatness and smoothness of the liner surface, this invention also provides first air extraction holes 35 at the edges of the upper template 11 and lower template 21, respectively, passing through the upper mold 10 and lower mold 20 and connecting to the cavity 30. The first air extraction holes 35 are located at the edges of the packaging liner, and the edge of the packaging liner abuts against the sponge support inside the mobile phone box. The air extraction holes cause the bulges formed by the wet pulp blank to concentrate at the edges, reducing the unevenness caused by the bulges, thereby improving the quality and appearance of the product. More preferably, second and third air extraction holes are also concentrated at the center of the upper mold 10 and lower mold 20. Since the central part of the packaging liner is used to open holes for easy separation of the liner from the mobile phone box, and the wet pulp blank here is waste material to be removed in subsequent processing, opening them here will not affect the flatness and appearance of the product. The second and third air extraction holes can be staggered, with the air extraction directions on both sides slightly offset, which not only prevents mutual suction on both sides from reducing the air extraction effect but also improves the air extraction efficiency.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
