本发明中公开了一种仪表板搪塑发泡密封结构及发泡工艺,涉及汽车配件设计制造领域,该发泡密封结构包括仪表板本体骨架、搪塑表皮和发泡层,所述发泡层所在的发泡区域采用闭模发泡并配置有发泡料浇注口,在所述仪表板本体骨架与搪塑表皮的前端区域设有第一软密封结构;在所述仪表板本体骨架与搪塑表皮的后端区域设有第一硬密封结构;通过实施本技术方案,可有效解决现有搪塑发泡仪表板产品质量合格率低的技术问题,采用软密封结构与硬密封结构巧妙结合,可有效提高产品搪塑发泡成型后的成型质量,同时制成的仪表板发泡件厚度较厚,手感柔软舒适,以使整体品质大幅提高。

    The invention discloses an instrument board slush molding foaming sealing structure and a foaming process, and relates to the field of automobile accessory design and manufacture, the foaming sealing structure comprises an instrument board body framework, a slush molding skin and a foaming layer, and the foaming area where the foaming layer is located adopts closed mold foaming and is provided with a foaming material sprue gate; a first soft sealing structure is arranged in the front end area of the instrument board body framework and the slush molding skin. A first hard sealing structure is arranged in the rear end area of the instrument board body framework and the slush molding skin. By means of the sealing structure, the technical problem that an existing slush molding foaming instrument board is low in product quality percent of pass can be effectively solved, a soft sealing structure and a hard sealing structure are ingeniously combined, the forming quality of the product after slush molding foaming forming can be effectively improved, and meanwhile a manufactured instrument board foaming piece is large in thickness, soft and comfortable in hand feeling. Therefore, the overall quality is greatly improved.
