Composite laminated plate manufacturing mold

Abstract

The invention discloses a composite laminated plate manufacturing mold. Through the composite laminated plate manufacturing mold, the thickness of laminated plates can be adjusted continuously and accurately. A lower mold surface is provided with stepped grooves. The first stepped groove is internally provided with the lower mold surface. The second stepped groove is provided with an upper top plate. The lower mold surface is provided with ejector pin holes allowing ejector pins to move vertically. The bottom surface of a lower mold is provided with locking devices used for locking push rods.The push rods are provided with graduations. The thickness of a mold cavity can be visually observed through the graduations. The upper and low mold surfaces are provided with sealing grooves for containing seal rings to guarantee the airtightness of the mold cavity. Heating pipes are arranged in an upper mold and the lower mold and can increase the temperature of the mold, so that the fluidity ofresin in the mold cavity is improved. Different thicknesses of laminated plates can be set according to different fiber cloth thicknesses. The fiber volume fraction of products can be controlled by calculating and controlling the content of resin in the laminated plates. Accordingly, the product quality is improved.

Description

technical field [0001] The invention relates to a composite material forming technology, in particular to a composite material laminate production mold whose thickness can be continuously adjusted. Background technique [0002] With the increasing environmental problems, the requirements for automobile exhaust emissions are becoming more and more stringent, and one way to reduce automobile exhaust emissions is to reduce the weight of automobiles. At the same time, an important way to achieve lightweight automobiles is to use new composite materials. Composite material manufacturing processes include hand lay-up molding, vacuum bag molding, resin injection molding, vacuum-assisted resin injection molding, etc. Among them, resin injection molding and vacuum-assisted resin injection molding have high requirements on the precision of the mold, and the surface accuracy of the mold and Poor sealing can easily cause various defects in the product.

AI Technical Summary

Problems solved by technology

Composite material manufacturing processes include hand lay-up molding, vacuum bag molding, resin injection molding, vacuum-assisted resin injection molding, etc. Among them, resin injection molding and vacuum-assisted resin injection molding have high requirements on the precision of the mold, and the surface accuracy of the mold and If the sealing is not good, it is easy to cause various defects in the product

[0003] Traditional resin injection molding molds are composed of simple upper and lower molds. The upper and lower molds use grooves or add specific thickness gaskets between the upper and lower molds to control the thickness of the product. However, due to manufacturing accuracy and processing errors, gaskets with too small thickness cannot be made. Thinner products cannot be obtained, and products of ideal thickness cannot be accurately produced, so that specific needs cannot be met

Poor sealing will also lead to defects such as air bubbles and dry spots in the product. Since the mold is generally a steel mold, the temperature of the resin flowing in the steel mold is too low, which will easily cause incomplete infiltration and affect the quality of the product.
