Description

Technical Field

[0001] The invention belongs to the technical field of automobile interior decoration, and particularly relates to a foaming mold for switching between full leather and half leather of an automobile instrument panel and a use method thereof. Background Art

[0002] Automobile instrument panel foaming mold is a commonly used mold in the automobile interior industry, so the foaming mold plays an extremely important role in the manufacturing process of automobile instrument panel.

[0003] In the prior art, the foaming molds used by automobile instrument panel manufacturers are all full-skin foaming molds, that is, the upper and lower parts of the instrument panel are formed by one-time mold-joining. Such molds can only produce full-skin instrument panels of one material. For example, the invention disclosed in the application number CN201410478558.0 discloses a "method for covering the surface of an automobile instrument panel". The method is to lay the surface of the instrument panel on the fixed mold side of the instrument panel foaming mold, and position the surface of the instrument panel in the overlapping area by a slider; the slider in the overlapping area of ​​the fixed mold is withdrawn to avoid interference between the slider and the instrument panel skeleton of the movable mold after mold-joining; the movable mold of the foaming mold brings the instrument panel skeleton into the fixed mold for mold-joining, and the slider in the fixed mold has been completely withdrawn at this time, and will not cause interference between the slider and the movable mold; after mold-joining, the foaming material is poured into the cavity formed between the movable mold of the foaming mold and the surface of the fixed mold bottom, and when the foaming material flows to the overlapping area, the surface of the instrument panel and the instrument panel skeleton are sealed; the invention can realize the covering of the low surface on the high instrument panel skeleton, but it can only produce full-skin instrument panels of one material.

[0004] The invention with application number CN202110432764.8 discloses "an environmentally friendly, efficient and low-cost instrument panel soft-touch molding process," which includes the following steps: (1) using modified thermoplastic elastomer particles to form an instrument panel soft-touch skin by injection molding; (2) loading the instrument panel skeleton and the instrument panel soft-touch skin into the foaming molding mold respectively; (3) closing the foaming molding mold and pouring PU foaming material to form a PU foaming layer; (4) forming parts after the foaming molding mold is opened, taking out the parts from the lower mold, and maturing the product. This invention can only produce a full leather instrument panel of one material.

[0005] Since the upper surface of the dashboard in high-end cars needs to use higher-end material genuine leather pieces with sewing decorative lines, this sewn genuine leather cannot be foamed directly, but the imitation leather on the upper surface needs to be removed after foaming and then bonded to the upper surface of the dashboard. Therefore, it is necessary to provide a foaming mold for two materials with secondary molding, that is, the upper and lower parts of the dashboard are foaming molds formed by different materials. Usually, the lower surface is made of polyurethane (PUR) material, and the upper surface is reusable silicone imitation leather. After molding, the silicone imitation leather can be peeled off, and then half of the leather is foamed for spraying and covering the genuine leather surface with sewing decorative lines. However, the same existing foaming mold cannot produce both full leather foaming and half leather foaming products.

[0006] The invention with application number CN201810522494.8 discloses "a kind of slush instrument panel foaming mold", which includes a mold body; the mold body includes an upper mold, a lower mold and a plurality of sliders, the upper mold, the lower mold and the sliders cooperate with each other, the plastic frame is installed on the upper mold through a frame positioning mechanism, the skin is adsorbed on the lower mold through a vacuum adsorption structure, and a slider self-locking structure is installed on the corresponding slider, and an inflatable sealing strip groove is arranged around the upper mold, and inflatable sealing strips are evenly distributed in the inflatable sealing strip groove. The inflatable sealing strip is divided into several sections to form a closed loop together. This invention only improves the slider self-locking structure, designs corresponding self-locking structures for sliders in different positions, makes the slider lock more firmly, and adopts an inflatable sealing strip design to make the foaming material evenly distributed in the instrument panel foaming mold cavity, and cannot realize the switching production of full-skin foaming and half-skin foaming products with the same set of foaming molds.
