[0039] Figure 1 A schematic diagram of a mold 100 according to an embodiment of the present utility model is shown. Figure 2 A cross-sectional view of the upper mold of the mold 100 according to an embodiment of the present utility model is shown. Figure 3 A schematic diagram of the lower mold of the mold 100 according to an embodiment of the present utility model is shown. The following is combined with Figures 1 to 3 for a detailed description.

[0040] As Figures 1 to 3 shown, the mold 100 includes an upper mold and a lower mold. Among them, the upper mold can be used as a moving mold, and the lower mold can be used as a fixed mold. The upper mold and the lower mold cooperate with each other to accurately and orderly fold multiple areas of the paper. The upper mold includes an upper template 110 and a movable plate 120. Among them, the movable plate 120 is connected to the lower side of the upper template 110 and is configured to move along a first direction (the first direction is perpendicular to the upper template 110). One or two upper mold cores 130 are connected to the lower side of the movable plate 120, and one or two upper mold cores 130 are connected to the lower side of the upper template 110. For example: in Figures 1 to 3 the shown embodiment, two upper mold cores 130 are connected to the lower side of the movable plate 120, and two upper mold cores 130 are connected to the lower side of the upper template 110. Among them, the movable plate 120 is located between the two upper mold cores 130 on the lower side of the upper template 110. The lower mold includes a lower template 140 and a plurality of lower mold cores 150. Among them, the lower template 140 is located directly below the upper template 110, and the lower mold cores 150 are connected to the upper side of the lower template 140. Among them, the plurality of upper mold cores 130 correspond to the plurality of lower mold cores 150 one by one. A core is provided on the lower side of the upper mold core 130, and a cavity matching the core is provided on the upper side of the lower mold core 150, so that the upper mold core 130 and the lower mold core 150 cooperate with each other to accurately fold an area of the paper.

[0041] When folding the die-cut paper using the mold 100, the paper can be first placed between the upper mold and the lower mold, and then the upper mold is driven to move downward. During the downward movement of the upper mold, the upper mold core 130 fixed on the movable plate 120 first contacts the paper, and cooperates with the corresponding lower mold core 150 to fold one or two areas of the paper; subsequently, the upper mold core 130 fixed on the upper template 110 contacts the paper again, and cooperates with the corresponding lower mold core 150 to fold another or two areas of the paper. This process realizes precise and orderly folding of multiple areas of the paper, effectively avoiding tearing and damage that may occur during the folding process of the paper, ensuring that the folding quality of each product meets the standards, and guaranteeing the consistency of product quality.

[0042] Figure 4 The schematic diagram of the upper mold according to an embodiment of the present invention is shown, Figure 5 The partial structural schematic diagram of the upper mold according to an embodiment of the present invention is shown, such as Figure 2 、 Figure 4 and Figure 5 As shown, the mold 100 may further include a plurality of limit bolts 160 for connecting the movable plate 120 to the upper template 110. Specifically, a plurality of first guiding holes 111 are provided on the upper template 110, and the number of the first guiding holes 111 is the same as the number of the limit bolts 160. For example, in the embodiment shown in Figure 5 , both the limit bolts 160 and the first guiding holes 111 are provided with four, and they correspond to each other. The limit bolts 160 are movably arranged in the first guiding holes 111, the heads of the limit bolts 160 are located above the upper template 110, and the rod parts of the limit bolts 160 extend out of the first guiding holes 111 and are threadedly connected to the movable plate 120.

[0043] According to an embodiment of the present invention, as shown in Figure 2 、 Figure 4 and Figure 5 As shown, a first guiding sleeve 112 is arranged in the first guiding holes 111, and the first guiding sleeve 112 is in sliding fit with the rod parts of the limit bolts 160, so as to ensure the smoothness of the sliding of the limit bolts 160 in the first guiding holes 111. Optionally, the first guiding sleeve 112 can be a copper sleeve, a linear bearing, etc. Optionally, the first guiding sleeve 112 is locked in the first guiding holes 111 by bolts to prevent the first guiding sleeve 112 from falling off the first guiding holes 111.

The springs 170 are configured to provide a force that urges the movable plate 120 away from the upper template 110. After the mold 100 finishes folding the paper, the entire upper mold moves upward. At this time, under the dual action of the elastic force and gravity of the spring 170, the movable plate 120 will automatically move away from the upper template 110 and smoothly return to its initial position.

[0045] According to an embodiment of the present invention, as Figure 2 and Figure 3 shown, a plurality of second guiding holes 113 are provided on the upper template 110. A plurality of guiding columns 180 are connected to the upper side of the lower template 140. The guiding columns 180 extend along the first direction and are inserted into the corresponding second guiding holes 113. The guiding columns 180 are slidably engaged with the second guiding holes 113. By providing the guiding columns 180 and the second guiding holes 113, the upper mold and the lower mold can be accurately closed, which is beneficial to improving production efficiency and production quality. Optionally, a second guiding sleeve (not shown in the figure) is provided in the second guiding hole 113. The second guiding sleeve is slidably engaged with the guiding column 180. Optionally, the second guiding sleeve can be a copper sleeve, a linear bearing, etc.

The lower mold core 150 is detachably connected to the upper side of the lower template 140. This detachable setting not only makes the repair and maintenance of the mold 100 more convenient, but also enables the user to replace the corresponding upper mold core 130 and lower mold core 150 according to different product requirements, so that there is no need to redesign or manufacture the entire mold 100, which is beneficial to improving the utilization rate of the mold 100 and reducing production costs.

[0047] According to an embodiment of the present invention, as Figure 2 、 Figure 4 and Figure 5 shown, the core can include a first protrusion 131 and a second protrusion 132. Among them, the first protrusion 131 extends along the second direction (i.e., the width direction of the upper template 110 and the lower template 140), and the longitudinal section of the first protrusion 131 is generally triangular. There are four second protrusions 132. Among them, two second protrusions 132 are provided on one side of the first protrusion 131 (for example Figure 2 the left side in), and the other two second protrusions 132 are provided on the other side of the first protrusion 131 (for example Figure 2 the right side in). As Figure 3As shown, the mold cavity may include a first groove 151, a second groove 152 and a third protrusion 153, wherein the first groove 151 extends along the second direction, the longitudinal section of the first groove 151 is substantially the same as the longitudinal section of the first protrusion 131, and six third protrusions 153 are provided, wherein three third protrusions 153 are provided on one side of the first groove 151 (for example Figure 3 The other three third protrusions 153 are arranged on the other side of the groove (eg Figure 3 Optionally, a pressing knife 190 is embedded in the first protrusion 131, the second protrusion 132, and the third protrusion 153, and a pressing knife 190 is also embedded in the second groove 152. The arrangement of the pressing knife 190 enables the mold 100 to accurately apply pressure to ensure accurate deformation of the paper during the folding process.

[0048] According to one embodiment of the utility model, Figure 2 , Figure 4 and Figure 5 As shown, a mounting groove 115 is provided on the lower side of the upper template 110, and the movable plate 120 is movably provided in the mounting groove 115.
