Problems solved by technology

[0007] In addition, there is no additional structure on the back of the hemp fiber board after hot pressing. In order to meet the performance of the part, the injection molding structure on the back needs to be connected to the hemp fiber skeleton by welding or bonding.
[0008] The above-mentioned process requires a large investment in molds, long processing time, high cost of parts, and the need to use glue and other production auxiliary materials that easily lead to excessive emission performance of parts, which is not conducive to the processing and use of products

Abstract

The invention discloses a hot pressing injection mold for integral hot pressing injection molding of a fibrilia plate and a surface layer thereon. The mold comprises a lower mold, an upper mold and a vacuum pump, wherein the upper mold is movably arranged on the lower mold; a cavity is formed in the upper mold; a core fitting the cavity is arranged on the lower mold; a sealing ring is arranged between the upper mold and the lower mold; multiple through holes are formed in the upper mold, and are respectively communicated with the vacuum pump; and a gate for pouring a material into the core is arranged on the lower mold. The invention further discloses a processing technology. In the hot pressing injection mold and the processing technology provided by the invention, glue is not needed in the processing process, so that the processing technology is simplified; and an injection molding part and a reinforcing rib are integrally formed on the back surface of the fibrilia plate, so that the structural strength is improved.

Description

technical field [0001] The invention relates to the technical field of processing the hemp fiber board and its skin layer, in particular to a hot-pressing injection mold and a processing technology for integrally forming the hemp fiber board and the skin layer. Background technique [0002] In order to improve product quality and create a warm, comfortable and luxurious interior atmosphere, the modern automobile industry often covers the surface of parts with fabric or artificial leather. Traditionally, the skeleton of the part is generally made by plastic injection molding process, and then the fabric and artificial leather are coated on the surface of the skeleton with an adhesive to complete the final part. [0003] On the other hand, under the development trend of automobiles that are increasingly emphasizing lightweight, energy saving and emission reduction, the hemp fiber thermoforming process has been widely used in the processing and manufacturing of automotive inter...
