Problems solved by technology

[0004] Since this inverted tooth is a flat tooth, a flat cutting knife is used for punching. However, in actual production, it is found that a large number of punching is not cut due to the wear of the cut or the elastic deformation of the cup cover itself. At the same time, the flat tooth Insufficient clearance between the inverted tooth and the edge of the cup does not affect the anti-loosening effect; in addition, the cutting knife of this structure punches from the left and right sides to the middle, so it can only punch the locking tooth with a flat incision

Embodiment Construction

[0028] Such as Figure 1-11 As shown, a stamping die for a cup cover includes an upper template 1 and a lower template 2, the upper and lower mold groups are matched by guide posts and guide post sleeves, and several cores or pressure plates are arranged on the upper template 1 11. A number of cavities 21 corresponding to the cores or pressure plates are set on the lower template 2. The cavities 21 are arranged in one or several groups in a straight line, and slide plates are arranged on both sides of each group of cavities 21 arranged in a straight line. 3. A clamping push structure is provided between the slide plate 3 and the upper template, and the slide plate 3 is set on the lower template 2 through the guide rail 61 and the slider 62; the slide plate 3 is provided with a push block 30; the cavity 21 There is a guide groove 22 on the outside corresponding to the position of the push block 30, and a gap 23 is opened at the position corresponding to the guide groove 22 on t...

Abstract

The invention relates to a punching die for clamping teeth of a cup lid. An existing plain-end cutting knife is changed into a V-shaped or inverted-V-shaped pointed cutting knife, the clamping teeth are changed from plain-end teeth into V-shaped teeth or inverted-V-shaped clamping teeth, the pointed cutting knife can ensure that the cup lid is pierced during each punching, and the matching allowance between the V-shaped teeth or the inverted-V-shaped teeth and an edge opening of a cup body is large so that a better disengagement prevention effect is achieved; meanwhile, the structure of the punching die is also appropriately changed for solving the problem that the cutting knife is abraded, and the notch width can be adjusted and the service life of the cutting knife can be prolonged by increasing or decreasing gaskets; and the punching die has the characteristics of reasonable structure, good reliability and convenience in adjustment.

Description

technical field [0001] The invention relates to a punching die, in particular to a punching die for a disposable cup lid latch. Background technique [0002] For example, CN205267729U discloses a cup cover on a disposable drinking cup. The cup cover is made of a transparent material, and the upper surface of the cup cover is covered with a printing layer except the central area of ​​the top. The inner side of the lower edge of the cover is provided with a circle of inverted teeth and convex grooves; when in use, the inverted teeth are clamped on the lower side of the upper edge of the cup body, which has a better anti-off effect, and at the same time cooperates with the convex grooves from the edge of the cup body. The upper and lower sides interact to fasten the cup cover and the cup body, ensure the sealing between the cup cover and the cup body, and enhance the reliability of the connection between the cup cover and the cup body. [0003] In order to use this kind of inv...
