Embodiment Construction

[0013] First, the front area of ​​the instrument panel is sealed with a soft seal.

[0014] The specific method is: open a U-shaped groove for the foaming mold located at the front edge of the instrument panel, and place the inflatable sealing strip in the U-shaped groove; the inflatable sealing strip is composed of two silicone tubes and a silicone The outer diameter of the silicone tube is 10 mm, and the inner diameter is 7 mm; choose a silicone strip with a diameter of 6.7 mm and a four-leaf petal-shaped cross-section to install in the silicone tube; insert both ends of the inflatable sealing strip into the port of the inflatable core ;

[0015] Second, the left and right sides of the instrument panel are sealed with copper blocks (sliders), that is, hard seals. Hard seals are used near the main and co-pilot positions.

[0016] The specific method is: before foaming, first clean the mold cavity with high-pressure blower, and then heat the foaming mold to about 45°C with w...

Abstract

The invention discloses a peripheral sealing process of a foamed instrument panel and a processing technology of automotive interior parts, mainly solving the problems of leakage and lack of materials, and the like of an existing peripheral sealing process of the foamed instrument panel. The peripheral sealing process comprises the following steps: sealing the front edge of the instrument panel bya soft seal, and placing an inflatable sealing strip in a U-shaped groove of a foaming mold; inserting both ends of the inflatable sealing strip into an inflatable core port; heating the foaming mold, paving the surface in a fixing mold to enable the surface to be adsorbed on the fixing mold, placing an instrument panel skeleton on the surface, closing a moving mold and the fixing mold, pressingcopper blocks on the left and right sides of the instrument panel against the surface by a cylinder, and pushing the inner side against the instrument panel skeleton by the moving mold to achieve thesealing effect. The main and co-driver positions are pressed against a sealing rib by the interaction of the moving mold and the fixing mold of the foaming mold to achieve the sealing effect. The sealing strip can be pressed against the front end of the instrument panel after being fully filled to achieve the sealing effect. The peripheral sealing process has the advantage of avoiding the problemof leakage and lack of materials of the foamed product.

Description

Technical field: [0001] The invention relates to a processing technology of an automobile interior decoration, in particular to a peripheral sealing technology in the processing of a foamed instrument panel. Background technique: [0002] Due to the rapid development of the automobile industry, the requirements for the quality and feel of automobile interior decoration are extremely high. For mid-to-high-end sedan models, foaming is an indispensable process. The foaming molding process is as follows: the skin is formed by slush molding process, and the formed The epidermis is put into the foaming mold, and the epidermis is adsorbed on the fixed mold through the adsorption function, and then put into the skeleton, the foaming mold is closed, and then the polyol combination material and isocyanate (commonly known as A material, B material, etc.) are injected into the foaming mold. material), and a small amount of catalyst, through chemical reaction, foam molding is carried out...
