Description

Technical Field

[0001] The present application relates to the technical field of cup cover production molds, and in particular to a cup cover forming mold with a display screen. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] However, when producing some products that need to have objects built in (such as a cup lid with a display), an insert is generally added to the core position of the built-in object. After injection molding, the insert is ejected with the product, and then the insert is taken out and the object (display) is embedded in the insert position of the product (cup lid) to complete the production. However, this production method is very troublesome. Each product needs to be manually installed and ejected, which has low production efficiency, and the insert is easily damaged and needs frequent maintenance and replacement, which is very inconvenient.

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] like Figures 1 to 5 As shown, the embodiment of the present application proposes a cup cover forming mold with a display screen, comprising an upper mold group 1 and a lower mold group 2, and a core 3 arranged on the lower mold group 2, characterized in that the lower mold group 2 is movably provided with display screen slides 4 on both sides of the core 3, one end of the display screen slide 4 is provided with a forming part 40 for placing the display screen, the core 3 is provided with a space avoidance groove 30 for inserting the forming part 40, the display screen slide 4 is provided with an oblique linkage groove 5, and the upper mold group 1 is provided with a linkage rod 6 which can be embedded in the oblique linkage groove 5 and can drive the display screen slide 4 to slide.

[0023] By arranging display screen rows 4 on both sides of the core 3 and arranging a molding part 40 at one end of the display screen row 4, before injection molding, the display screen is placed in the molding part 40 in advance, and then cooperates with the air avoidance groove 30 to directly move the display screen to the installation position and be integrally formed with the cup cover. No additional inserts are required, and no subsequent installation is required, which reduces the production steps and greatly improves the production efficiency. At the same time, through the coordinated setting of the oblique linkage groove 5 and the linkage rod 3, when the upper mold group 1 is demolded, the linkage rod 6 and the oblique linkage groove 5 are moved in coordination to synchronously drive the display screen row 4 to move away from the product. It is practical and convenient, realizes automatic demolding of the row, simplifies the mold structure, saves costs and space, and greatly improves production efficiency.

[0024] Furthermore, the linkage rod 6 includes a moving part 61 connected to the upper mold assembly 1, and a linkage part 62 disposed at the lower end of the moving part 61 and capable of being embedded in the oblique linkage groove 5. The moving part 61 is connected to the upper mold assembly 1, and can move together with the demoulding of the upper mold assembly 1, and synchronously drive the linkage part 62 to move, which is practical and convenient.

[0025] Furthermore, the oblique linkage groove 5 is inclined from the upper right to the lower left, and the linkage portion 62 is inclined correspondingly to the oblique linkage groove 5 .

[0026] Demoulding: The upper mould group 1 and the lower mould group 2 move back to back to open the mould, driving the linkage rod 6 to move vertically upward. Since the linkage part 62 is inclined correspondingly to the oblique linkage groove 5, when the linkage rod 6 moves vertically upward, it will drive the display screen row 4 to move synchronously to the outer side of the lower mould group 2 to separate from the product, thereby realizing automatic demoulding of the display screen row 4. This is practical and convenient, simplifies the mould structure, saves costs and space, and greatly improves production efficiency.

[0027] Furthermore, the angle between the side wall of the oblique linkage groove 5 and the lower die set 2 is α, and the value of α ranges from 45° to 80°.

[0028] In this embodiment, the value of α is 70°.

[0029] Furthermore, the lower module 2 is provided with a row slot 20, and the display row 4 is also provided with a sliding part 41 that can slide in the row slot 20. It is ensured that the display row 4 does not deviate toward the outer side of the lower module 2, and the display row 4 can be separated from the product.

[0030] Specifically, the core 3 includes a mold core 31 disposed on the lower mold assembly 2 , and two cup cover molding surfaces 32 are arranged side by side on the mold core 31 . The two air avoidance grooves 30 are opened on opposite sides of the cup cover molding surfaces 32 .

[0031] Two cup lids can be produced by injection molding at one time, which doubles the production efficiency and is practical and convenient.

[0032] Furthermore, the number of the display screen rows 4 is four, which are respectively arranged on the opposite sides of the two cup cover forming surfaces 32.

[0033] Specifically, a locking rod 7 is provided between the upper die set 1 and the lower die set 2, and both ends of the locking rod 7 are connected to the upper die set 1 and the lower die set 2 through nuts 70. When the mold is not in use, the position between the upper die set 1 and the lower die set 2 is locked by the locking rod 7 to keep the mold in a closed state and protect the mold.
