AI Technical Summary

Technical Problem

In the prior art, the bond between the leather layer and the functional structure is not firm, and problems such as falling off, curling edges or aging are prone to occur, which affects the quality and service life of the product.

Method used

A liquid silicone-covered leather mold is designed to form a mold cavity through the combination of the front mold kernel and the rear mold kernel. The first and second positioning structures are used to ensure that the liquid silicone is uniformly bonded to the leather and functional structure to form a solid silicone sealing layer.

Benefits of technology

It realizes high-strength bonding between the leather layer and the functional structure, avoids the problem of delamination, improves the service life and touch of the product, and at the same time shortens the forming time and improves production efficiency.

Abstract

The utility model discloses a forming mold for liquid silicone coated leather, comprising a front mold assembly, a front mold core, a rear mold core, and a rear mold assembly. The front mold core and the rear mold core are combined to form a forming cavity. The front mold core is provided with a forming surface matching the functional structure of the part to be formed, and the forming surface is provided with a first positioning structure. The rear mold core is provided with a concave surface matching the leather layer of the part to be formed, and the concave surface is provided with a second positioning structure for positioning the part to be formed. The utility model solves the problem that liquid silicone is prone to falling off, warping or aging during the use of a facial mask product, thereby affecting product quality.
