Abstract

The utility model relates to a mould for producing composite material products. Three to five mould plates 1 are arranged orderly, every two mould plates can be connected by hinges, an inner mold 3 is arranged on expanding mould plates 1, and folding mould plates 1 are fastened by mould clamps. Due to the adoption of the folding mould plates 1, the total quantity of the moulds is reduced, the moulds can be used repeatedly, and the availability ratio of the moulds can be increased. The thickness of the products produced is uniform with high strength and good smoothness. The utility model has the advantages of simple structure, convenient operation, easy demoulding, low cost, high productive efficiency, etc.

Description

A kind of mould of making composite product

The utility model relates to a kind of mould, particularly a kind of folding mould of making composite product.

The process of traditional making composite product all adopts fixed and split pin-connected panel mould.Its production process is earlier calcium grease (interleaving agent) or car wax evenly to be applied to die surface, then head is applied on the mould all over slurry, stick glass wool cloth and roll bubble, be coated with slurry again, stick glass wool cloth, up to reaching required thickness, press polish, roll bubble, blanks and moulding and conserving, finally demould, because traditional mould is fixed and the split pin-connected panel, therefore exist a lot of problems.For example, the mould demand is big, demoulding difficulty, and mould semi-finished product well damage, inconvenient operation, the product became uneven of producing, intensity, fineness are poor, can not ensure the quality of products, production efficiency is low or the like.Though people have done many improvement to mould at present, but still exist above-mentioned problem.

The purpose of this utility model is to provide a kind of mould of novel manufacturing composite product, it simple in structure, easy to use, cost is low, because this mould can fold, therefore can use repeatedly, the demoulding easily, good, the production efficiency of the intensity height of product, smoothness is high carries out mass production.

The utility model is a kind of mould of making composite product, comprises template (1), internal mold (3), and its feature is:

A.3-5 piece template (1) is arranged in order, connect with hinge (2) between the template (1),

B. internal mold (3) is a solid shape, places on the expansion template (1) that is covered with mylar and composite, turns up template (1), and is fastening with the mould clip.

The utility model is owing to adopted folding template (1) and internal mold (3) to match, therefore reduced the mould total amount, improved the utilization rate of mould, and can use repeatedly, the demoulding is easy, and the thickness of product is even, and intensity height, fineness are good, it also has simple in structure, easy to use, with low cost, production efficiency advantages of higher simultaneously.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Figure one is the unfolding assumption diagram according to the template of a kind of mould of making composite product that the utility model proposes;

Figure two is the foldable structure figure according to the template of a kind of mould of making composite product that the utility model proposes;

Figure three is the profiles according to the inner membrance of a kind of mould of making composite product that the utility model proposes.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

In the process of producing cable protective trough, use mould to be timber structure.3 templates (1), each sheet skeleton all adopts the high-quality flitch, and with nail nail rectangularity framework, the smooth firm ground nail of paper overlaid plywood that cuts same size with it then is on framework.3 templates are arranged in order, and connect with 4 hinges (2) between per 2 templates (1), and external mold has just been finished like this.Internal mold then adopts the high-quality high density plate material, cuts into four block length square plates, is fixed with tapping screw.

Earlier template (1) is launched during production, be tiled on the workbench, the special-purpose mylar that to be wider than template (1) is put on the template (1), the slurry that will modulate in advance is applied on the film equably then, apply one deck glass wool cloth again, be coated with slurry again second time, stick another layer glass wool cloth ... until reaching designing requirement.The wide polyester film that goes out is folding, encase product surface, contained bubble in the slurry is rolled fully, after the surface press polish reaches specification requirement, internal mold (3) is positioned over rational position, makes template (1) it reach required angle, position with manpower or machinery, be fixed on the mould with the mould clip.At last, a whole set of mold formation is stacked in aeration-drying place, treat the reasonable maintenance moulding of goods after, open the mould clip, finished product is promptly thrown off with mould.

Claims (1)

1. a mould of making composite product comprises template (1), and internal mold (3) is characterized in that:

A.3-5 piece template (1) is arranged in order, connect with hinge (2) between the template (1),

B. internal mold (3) is a solid shape, places on the expansion template (1) that is covered with polyester book film and composite, turns up template (1), and is fastening with the mould clip.
