Problems solved by technology

This process has certain advantages: coating red wax can improve the smoothness of the mold surface; improve the working environment of the mold, the surface of the cavity is smoother, which is conducive to the demoulding of the product; but there are too many defects: the coating will volatilize harmful odor when heated It affects human health; it cannot be recycled for a long time, and the later maintenance cost is high; the foamed product has a certain smell, which reduces the pass rate of the product

Embodiment Construction

[0018] Refer to attached Figure 1-2 , Example 1

[0019] A kind of porcelain plating process on the surface of the PU foam mold cavity of automobile headrest, the steps are as follows,

[0020] 1) Clean and degrease the surface of the automotive PU foam mold cavity, heat the mold to 385°C and keep it warm for 30 minutes;

[0021] 2) Sand blasting treatment, using 100 mesh quartz sand blasting treatment;

[0022] 3) After lowering the mold temperature to 50°C, start spraying the ceramic coating, and spray evenly through the coating tool, spray once, and the thickness of the coating formed by spraying is 40 microns;

[0023] 4) After spraying, heat the mold to 120°C and keep it warm for 10 minutes. Continue to heat the mold to 180°C and keep it warm for 10 minutes. Finally, heat the mold to 230°C and then vitrify it for 30 minutes. Cool naturally to complete the porcelain plating .

[0024] The automobile PU foaming mold is an automobile headrest mould, an automobile armres...

Abstract

The invention relates to an automobile PU foaming mold cavity surface ceramic plating process. The automobile PU foaming mold cavity surface ceramic plating process includes the following steps that 1), the surface of an automobile PU foaming mold cavity is cleaned and degreased, a mold is heated to 385 DEG C, and then heat preservation is carried out for 30 min; 2), sand blasting is carried out, specifically 70-100-mesh quartz sand is sprayed; 3), after the mold is cooled to 40-60 DEG C, spraying of ceramic plating coating is started, a coating tool is used for uniform spraying, the ceramic plating coating is sprayed to the mold once, and the thickness of a coating formed after spraying is 30-50 micrometers; and 4), after the mold is heated to 120 DEG C after spraying is completed, heat preservation is carried out for 10 min, after the mold continues to be heated to 180 DEG C, heat preservation is carried out for 10 min, finally, after the mold is heated to 220-240 DEG C, enamelation is carried out for 30 min, and after the mold is naturally cooled, ceramic plating is completed. The automobile PU foaming mold cavity surface ceramic plating process has the beneficial effects that the ceramic coating can resist the high temperature of 600 DEG C, and therefore the similar problems can be effectively avoided through the ceramic coating.

Description

technical field [0001] The invention relates to a process for processing the cavity surface of an automobile PU foaming mold, in particular to a porcelain plating process for the cavity surface of an automobile PU foaming mold. Background technique [0002] The surface treatment process of the existing automobile PU foaming mold cavity: mold surface red wax treatment mold surface red wax treatment: heat the mold to 120° (keep the temperature), and workers use a brush to evenly apply red wax to the mold cavity For the interior, wipe off the local excess coating after coating, and the coating will solidify on the surface of the mold after the mold cools down. This process has certain advantages: red wax can improve the smoothness of the mold surface; improve the working environment of the mold, the cavity surface is smoother, which is conducive to the demoulding of the product; but the defect is too big: the coating will volatilize harmful odor when heated It affects human he...
