Preparation method of carbon fiber automobile grill gauge

Abstract

The invention relates to a preparation method of a carbon fiber automobile grill gauge. The technical steps are as follows: designing and processing a mold, wherein the mold comprises an upper mold and a lower mold, the upper mold is provided with a glue injection opening and an air exhaust glue outlet; paving cloth, namely, paving the tailored carbon fiber cloth in an upper mold cavity and a lower mold cavity of the mold respectively to reach the designated thickness, and then assembling the mold; vacuumizing the mold cavities, injecting glue, curing, and demolding so as to obtain the carbon fiber automobile grill gauge. The carbon fiber automobile grill gauge is produced by taking a carbon fiber plate as a material and adopting a mold pressing and molding technique, has the advantages of light weight, high mechanical intensity and the like; a special cooling technology is not required, and curing can be implemented at room temperature, so that the technological difficulty is lowered, the technology is simplified, the production cycle is shortened, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of processing and manufacturing of inspection tools, in particular to a preparation method of a carbon fiber automobile grille inspection tool. Background technique [0002] The existing automobile grille inspection tool adopts injection molding process, including mold clamping, filling, pressure holding, cooling, demoulding and other steps, and most of the materials used are plastics. The existing technical defects are: 1. After injection molding The grille has welding marks (the welding marks are divided and merged by a number of streams in the mold during injection or extrusion. The melts are not completely fused at the interface, and they cannot be fused together, resulting in fusion marks) Not only Affect the appearance of plastic parts, and at the same time, due to the loosening of the microstructure, it is easy to cause stress concentration, which reduces the strength of this part and breaks; 2. In th...

Problems solved by technology

[0002] Existing automobile grille inspection tools adopt injection molding process, including the steps of mold closing, filling, pressure maintaining, cooling, demoulding, etc., and most of the materials used are plastics, and its technical defects are as follows: 1. After injection molding The grid has weld marks (the said weld marks are caused by the diversion and fusion of several streams of material in the injection or extrusion in the mold, and the melts are not completely fused at the interface, and they cannot be welded together, resulting in fusion marks) not only Affect the appearance of plastic parts, and at the same time, due to the loose microstructure, it is easy to cause stress concentration, which makes the strength of this part decrease and break; 3. The cooling stage accounts for 70-80% of the entire molding process cycle, and uneven cooling will cause warping and deformation of the product; 4. Improper demolding methods may cause uneven force on the product during demoulding , causing defects such as product deformation during ejection
