Abstract

The invention discloses a mold for defrosting thin wall forming. The mold comprises a mold body, a front mold body and a rear mold body, a mounting cavity is formed in the mold body, the front mold body and the rear mold body are arranged in the mounting cavity, the front mold body and the rear mold body are tightly attached to form a thin-wall forming cavity, a plurality of bent parts are arranged in the thin-wall forming cavity, first ejector pins are arranged at the bottoms of the multiple bent parts, a defrosting thin-wall plate at the bent parts can bear large thrust, the thrust provided by the first ejector pins is concentrated on the bent points of the bent parts, and therefore top white or top marks are prevented from occurring when the defrosting thin-wall plate is ejected out, and in addition, the invention provides a demolding system comprising the mold. The problem that a defrosting thin wall manufactured through a mold has top white or / and top marks can be solved.

Description

technical field [0001] The invention relates to the technical field of injection molds and demoulding, in particular to a mold and a demoulding system for defrosting thin-wall molding. Background technique [0002] The existing defrosting panels for automobiles, including the defrosting upper panel and the defrosting lower panel, are integrally injection molded by an injection mold. The thickness of the main panel of the injection molded defrosting door panel is 2.5 mm to 3 mm, and it has multiple bends and Mount. In order to reduce the material used and obtain the defrosting thin wall, the thickness of the main board of the defrosting door panel is reduced to 1.3mm, while the thickness of the mounting part remains unchanged. Among them, for the 1.3mm defrosting plate, when it is ejected, because the defrosting plate is thin, it is easy to appear whitening or top printing on the ejector pin. [0003] Therefore, a solution is urgently needed for the above-mentioned problems...
