Fibrilia plate product forming process and equipment

Abstract

The invention discloses a fibrilia plate product forming process and equipment, and relates to the field of injection molding. The process comprises the following steps: placing a skin heated to a preset temperature on the female die side of an injection mold; placing the fibrilia plate heated to the preset temperature on the male die side of the injection mold; vacuumizing the female die side toform the texture of the surface and the product shape, and meanwhile starting to close dies to form the fibrilia plate into the product shape; continuously heating the inside of the male die side to melt a polypropylene material in the fibrilia plate so that the skin can be bonded with the fibrilia plate; and performing injection molding on the male die side to form the product structure. According to the process, the technological process is optimized and shortened, and meanwhile personnel and working hours for production and the cost of molds for development in the earlier stage can be greatly reduced. Injection molding is used for replacing a traditional composite process, the use of glue is reduced, and the product can be more friendly to the environment.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to a molding process and equipment for hemp fiber plate products. Background technique [0002] Such as figure 1 As shown, the traditional hemp fiber product needs to go through five technological processes to obtain the shaped product. First, the pure hemp fiber product is obtained by hot pressing mold, and then the excess edge material is cut off by the trimming die to obtain the shaped hemp fiber product, and then Embed the hemp fiber product into the injection molding B-side structure through the injection mold to obtain the semi-finished skeleton, then spray and bake to obtain the spray glue product, and finally compound the skeleton and the skin through the female mold compound to obtain the hemp fiber product with the skin. [0003] The process of traditional hemp fiber products is relatively long, so many types of molds need to be invested in the early project development. ...

AI Technical Summary

Problems solved by technology

[0003] The process of traditional hemp fiber products is relatively long, so the early project development needs to invest in many types of molds

And due to the diversification of the process, a large number of personnel and equipment are needed for supporting production, and the product molding cycle is long

During the period, it is necessary to use glue for bonding, which affects environmental protection requirements, and the impact of odor experiments also needs to be considered
