Abstract
The invention discloses a manufacturing method of a fiber glass reinforced plastic mould, and belongs to the technical field of moulds. The manufacturing method comprises the steps that the fiber glass reinforced plastic mould is cleaned after water mill and polishing treatment and dried with a towel, and after the fiber glass reinforced plastic mould is completely dry, stripping wax is wrapped with three to four layers of gauze, a convolution method is adopted for coating the surface of the mould with the stripping wax, the mould is wiped with a white towel until the mirror surface effect is presented after three to five minutes, and the mould is stored for two hours; the operation of the last step is repeated for four times, and the mould is stored for more than six hours after the fifth operation is completed; and after the mould is coated with the stripping wax, a spray gun is used for conducting gel coating, the thickness of a gel coat of the mould is 1 mm, the gel coat is divided into two layers, the coating process is accomplished twice, each layer of the gel coat is 0.5 mm thick and coated for three times with the thickness of each time at 0.15-0.17 mm, and a gel coat ruler is adopted for measuring the thickness of the gel coat layers each time the gel coating is finished. The multihole, sagging, color separation and other phenomena of the gel coat layers are avoided, and the work efficiency and product quality are improved.
Description
Technical field
The present invention relates to technical field of mold, in particular to a kind of fiber reinforced plastic mold manufacture method.
Background technology
Fiber reinforced plastic mold is with resin as matrix material, and glass fibre is reinforcing material, and mould made on the basis of prototype.There is the advantages such as flexible, production development cycle short, good manufacturability, wear-resisting, the length in service life of molding.First make fiber reinforced plastic mold is to make master mold, i.e. product full pattern.
The operating process of mould gel coat is a vital step in Making mold, and all of rear laying and structural framework are all the gel coating resin services for die surface, and therefore mould gel coat material needs higher use and condition of cure than the gel coat of common product.High-quality die surface requires the most accurate mould gel coat operation and mixed process, but now in traditional handicraft, brush special is typically utilized to carry out master mold brushing mould gel coat material, so operation can cause the mould produced to produce more pore, operation to technical staff requires the highest, and the quality that have impact on product also have impact on production efficiency.
Summary of the invention
It is an object of the invention to provide a kind of fiber reinforced plastic mold manufacture method, to solve the problems referred to above.
For realizing the object of the invention, the technical scheme of employing is: a kind of fiber reinforced plastic mold manufacture method, comprises the following steps:
Fiber reinforced plastic mold cleaning good to water mill, polishing, by towel, after parching, with demoulding wax on 3 ~ 4 layers of bundle, employing convolution method is coated with on the mold surface uniformly, treats 3 ~ 5 minutes, wipes with white towel, until mirror effect, places 2 hours；
Repeating aforesaid operations totally 4 times, the 5th operation is placed more than 6 hours；
After being painted with mould release wax on mould, gel coat spraying is carried out with spray gun, mould gel coat thickness is 1mm, gel coat divides two-layer, spraying process to make two bites at a cherry, every layer of 0.5mm thickness, and every layer spray three times, a time 0.15mm ~ 0.17mm, after often having sprayed a gel coat, uses gel coat chi at the thickness of die surface metering gel coating resin；
After solidifying etc. third layer gel coat, one layer of resin mould of brush, spread layer of surface felt, repave layer of surface felt, repave 300 grams after solidification and strengthen viscous two-layer, be repeated 4 times；
Polishing with fine sand, polishing water polishes, and plays 8 waxes.
Further, after ground floor gel coat solidifies, could spray another layer of gel coat, hardening time is 90 minutes.
Further, spray first pass thickness is the mould gel coat of 0.15 mm ~ 0.17 mm, becomes vertical direction to spray second time gel coat with first pass, and thickness is 0.15 mm ~ 0.17 mm, then sprays last all over gel coat by the direction of first pass.
The invention has the beneficial effects as follows, gelcoat spray gun even application mould gel coat material on master mold is utilized to form gel coating resin, it is to avoid to cause the phenomenons such as the porous of gel coating resin, sagging, color separation, improve work efficiency and product quality, decrease the defect rate of mould and rate of returning something for repairs, extend service life.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
The fiber reinforced plastic mold manufacture method that the present invention provides, comprises the following steps:
Fiber reinforced plastic mold cleaning good to water mill, polishing, by towel, after parching, with demoulding wax on 3 ~ 4 layers of bundle, employing convolution method is coated with on the mold surface uniformly, treats 3 ~ 5 minutes, wipes with white towel, until mirror effect, places 2 hours；
Repeating aforesaid operations totally 4 times, the 5th operation is placed more than 6 hours；
After being painted with mould release wax on mould, gel coat spraying is carried out with spray gun, mould gel coat thickness is 1mm, gel coat divides two-layer, spraying process to make two bites at a cherry, every layer of 0.5mm thickness, and every layer spray three times, a time 0.15mm ~ 0.17mm, after often having sprayed a gel coat, uses gel coat chi at the thickness of die surface metering gel coating resin；
After solidifying etc. third layer gel coat, one layer of resin mould of brush, spread layer of surface felt, repave layer of surface felt, repave 300 grams after solidification and strengthen viscous two-layer, be repeated 4 times；
Polishing with fine sand, polishing water polishes, and plays 8 waxes.
After upper felt, per pass need to be through normal temperature cure in 24 hours.For avoiding be full of cracks or wrinkling, should could spray another layer of gel coat after ground floor gel coat solidifies, hardening time is 90 minutes.
Main mould 100-1200 sand papering also polishes.Spray first pass thickness is the mould gel coat of 0.15 mm ~ 0.17 mm, becomes vertical direction to spray second time gel coat with first pass, and thickness is 0.15 mm ~ 0.17 mm, then sprays last time gel coat by the direction of first pass, and the gel coat thickness of such ground floor is exactly 0.5 mm.Gel coat has sprayed latter 1 hour ~ 3 hours.In addition to beating solid mould release wax, to be on the safe side, last layer liquid can be smeared outside gently with sponge cured.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
