[0028] In the utility model, the box cover main body forming component 3 between the upper template 1 and the lower template 2 cooperates with the first color glue injection mechanism 12 to injection mold the fresh-keeping box cover. After the box cover is injection molded, the box cover is transferred to the glue strip forming component, and the second color glue injection mechanism 13 is cooperated to form a sealing glue strip on the box cover. This can realize that a box cover product with a sealing glue strip can be produced with one mold, which can greatly reduce the production cost of the box cover;

[0029] Specifically, the box cover molding cavity 7 formed by the combination of the No. 1 top mold 5 and the bottom mold 6 can produce a box cover product in cooperation with the No. 1 color glue injection mechanism 12. After the box cover is transferred between the No. 2 top mold 8 and the bottom mold 6, the box cover can be fixed by the box cover fixing mechanism 11. The No. 2 top mold 8, the bottom mold 6 and the box cover 9 can form a sealing strip on the box cover in cooperation with the No. 2 color glue injection mechanism 13.

[0030] Specifically, combined with Figure 3-Figure 5 As shown, the box cover fixing mechanism 11 includes a box cover fixing assembly composed of four box cover fixing assemblies that can enclose a rectangle. The box cover fixing assembly includes a box cover fixing block 14 and a driving assembly that can drive the box cover fixing block 14 to move toward or away from the rubber strip forming cavity 10. The driving assembly includes a driving rod 15 that is obliquely fixed on the upper template 1. The driving rod 15 is slidably matched with the box cover fixing block 14 through an oblique guide structure. When the rubber strip is produced, the driving rod 15 cooperates with the box cover fixing block 14 to fix the box cover. When the mold is opened, the upper template moves upward to drive the driving rod to move vertically upward. The driving rod moves vertically upward in combination with the oblique guide structure to drive the box cover fixing block 14 to move away from the rubber strip forming cavity 10, thereby enabling the box cover fixing block and the box cover to be separated so as to facilitate the box cover to be ejected from the lower template.

[0031] Specifically, the oblique guide structure includes a limiting slide groove 16 obliquely arranged on the box cover fixing block 14, the cross section of the limiting slide groove 16 is T-shaped, and the driving rod 15 is inserted into the limiting slide groove 16 and slidably cooperates with the limiting slide groove 16. The limiting slide groove 16 with a T-shaped cross section cooperates with the driving rod 15 to drive the box cover fixing block 14 to move toward or away from the rubber strip molding cavity 10.

[0032] Preferably, the No. 1 top mold 5 and the No. 2 top mold 8 are detachably connected to the upper mold plate 1 by a plurality of screws, and the bottom mold 6 is detachably connected to the lower mold plate 2 by a plurality of screws. The use of screw fixation can facilitate the disassembly of the No. 1 top mold 5, the No. 2 top mold 8 and the bottom mold.

[0033] Specifically, the No. 1 color glue injection mechanism 12 includes a No. 1 diverter plate 17 with a V-shaped cross section, and the two ends of the No. 1 diverter plate 17 are respectively connected to the two box cover main body molding components 3 through the No. 1 color injection tube 18. The No. 1 color glue can be injected into the two box cover molding cavities through the No. 1 diverter plate 17 and the No. 1 color injection tube 18 to form the box cover.

[0034] Specifically, the second color glue injection mechanism 13 includes a second diverter plate 19 with an I-shaped cross section, and the two ends of the second diverter plate 19 are respectively connected to the two rubber strip forming components 4 through two second color injection tubes 20. The second color glue can be injected into the two rubber strip forming cavities through the second diverter plate 19 and the second color injection tube 20 to form rubber strips.

[0035] Specifically, two ejection mechanisms corresponding to the box cover main body molding assembly 3 and the rubber strip molding assembly 4 are provided on the lower side of the lower template 2, and the ejection mechanism includes a top plate 21, a plurality of straight ejector rods 22, a plurality of inclined ejector rods 23, and two lifting drivers 24 that can drive the top plate 21 to rise and fall in the vertical direction. The action of the lifting driver can drive the top plate to rise and fall in the vertical direction, and the lifting and falling of the top plate in the vertical direction can drive the plurality of straight ejector rods 22 and the plurality of inclined ejector rods 23 to move upward to apply thrust to the product. The provision of two ejection mechanisms can realize the ejection of products at the box cover main body molding assembly 3 and the rubber strip molding assembly 4.

[0036] Those skilled in the art should understand that the lifting drive may be an oil cylinder, an air cylinder or a linear motor, etc.

[0037] The working principle of the utility model is as follows: the box cover main body forming component 3 between the upper template 1 and the lower template 2 cooperates with the No. 1 color glue injection mechanism 12 to injection mold the fresh-keeping box cover. After the box cover is injection molded, the box cover is transferred to the glue strip forming component, and the No. 2 color glue injection mechanism 13 can form a sealing glue strip on the box cover. This can realize that a pair of molds can produce box cover products with sealing glue strips, which can greatly reduce the production cost of the box cover. The box cover molding cavity 7 formed by the No. 1 top mold 5 and the bottom mold 6 cooperates with the No. 1 color glue injection mechanism 12 to produce the box cover product. After the box cover is transferred between the No. 2 top mold 8 and the bottom mold 6, the box cover fixing mechanism 11 can fix the box cover, and the No. 2 top mold 8, the bottom mold 6 and the box cover 9 cooperate with the No. 2 color glue injection mechanism 13 to form a sealing glue strip on the box cover;

[0038] When the rubber strip is produced, the driving rod 15 cooperates with the box cover fixing block 14 to fix the box cover. When the mold is opened, the upper template moves upward to drive the driving rod to move vertically upward. The driving rod moves vertically upward and cooperates with the oblique guide structure to drive the box cover fixing block 14 to move away from the rubber strip molding cavity 10, so that the box cover fixing block and the box cover can be separated to facilitate the box cover to be ejected from the lower template. The T-shaped limiting slide groove 16 cooperates with the driving rod 15 to drive the box cover fixing block 14 to move toward or away from the rubber strip molding cavity 10.

[0039] The use of screw fixation can facilitate the disassembly of the No. 1 top mold 5, the No. 2 top mold 8 and the bottom mold. The No. 1 color glue can be injected into the two box cover molding cavities through the No. 1 diverter plate 17 and the No. 1 color injection tube 18 to form the box cover. The No. 2 color glue can be injected into the two rubber strip molding cavities through the No. 2 diverter plate 19 and the No. 2 color injection tube 20 to form the rubber strip. The action of the lifting drive can drive the top plate to rise and fall in the vertical direction. The lifting of the top plate in the vertical direction can drive a number of straight ejector rods 22 and a number of inclined ejector rods 23 to move upward to apply thrust to the product. The provision of two ejection mechanisms can realize the ejection of products at the box cover main body molding component 3 and the rubber strip molding component 4.
