Description
Technical Field
The invention belongs to the technical field of injection molds, and particularly relates to a plastic nail injection molding tool mold.
Background
In practice, the plastic nails can be reliably sanded and sawed without damaging the tool. The tensile strength of the plastic nails and wood boards is comparable to, or even higher than, that of conventional metal nails. Because plastic nails do not age, rust, and corrode, their bond strength does not significantly diminish over time. Due to localized frictional heating during stapling, the plastic staples may slightly melt on the surface in contact with the product substrate. This creates a strong adhesive bond between the substrate and the nail that is stronger than conventional glues. The plastic nails have strong advantages in application, so that the market demands are greatly increased; at present, equipment capable of efficiently producing plastic nails is lacking in the market.
Therefore, a mold capable of efficiently producing plastic nails is needed to meet the increase of market demand supply, and therefore, the invention designs a plastic nail injection molding tool mold.
