AI Technical Summary
Existing molds are difficult to demold when producing seals with undercut structures, which can easily lead to product jamming, surface indentations, or flash, affecting production efficiency and product quality.
A strong demolding structure is designed, which uses an outward-moving cutting nozzle cavity and a thickened tearing edge cavity, and is made of quenched alloy steel. The combination of the inverted triangular structure of the cutting nozzle cavity and the thickened tearing edge cavity ensures that the product has sufficient bonding force during demolding, avoids the product sticking to the mold core, and simplifies the demolding process.
It enables non-destructive and rapid demolding of the inverted structure, improves production efficiency and product qualification rate, ensures product surface quality, reduces flash and indentation problems, and enhances the wear resistance and service life of the mold.

Abstract
Claims
1. A mold structure for strong unsealing head, comprising an upper mold (100) and a lower mold (200), characterized in that: a forming cavity (300), a tearing edge cavity (301) and a cutting nozzle cavity (302) are formed between the upper mold (100) and the lower mold (200); two tearing edge cavities (301) and two cutting nozzle cavities (302) are provided, the two sides of the forming cavity (300) are connected with the tearing edge cavities (301), and the outside of the tearing edge cavities (301) is connected with the cutting nozzle cavities (302); a reverse mold core (101) is arranged at the lower end of the upper mold (100), and the reverse mold core (101) is located in the forming cavity (300).
2. A mold structure for a strong decap according to claim 1, wherein The shape of the reverse mold core (101) matches that of the forming cavity (300), and it is used for forming the inner surface of the product.
3. A mold structure for a strong decap according to claim 1, wherein The thickened structure of the tearing edge cavity (301) is used to provide sufficient connecting force, so that the product can be deformed by pulling and separated from the reverse mold core (101) when demolding.
