Abstract
The invention provides a method for manufacturing an engine room cover with a bright and clean surface through vacuum introduction, which comprises the following steps: step 1, preparing a die, cleaning up the surface of the die and then spraying a releasing agent thereon for at least one time, and airing the die completely; step 2, paving a product material paving layer on the die processed in the step 1 according to the stated size and paving thickness; step 5, covering the die with a vacuum thin film, sealing the periphery, and finally pouring resin into the die from an inlet and discharging redundant resin from an outlet. The method is characterized by comprising a step 3 and a step 4 between the step 2 and the step 5: step 3, paving a high permeability fabric on the product material paving layer; and step 4, placing a floating upper die with a bright and clean surface on the high permeability fabric. The method has the advantages that the vacuum introduction process can be finished without adopting a flow guiding medium, an engine cover hood product with two bright and clean surfaces can be obtained, and the manufacturing cost is obviously reduced.
Description
Technical field
The present invention relates to a kind of vacuum introduction manufacture method of engine room cover of tool smooth finish surface, belong to resin vacuum guiding and forming technique technical field.
Background technology
In order to reduce cost of electricity-generating, power of fan constantly increases.Correspondingly, the size of engine room cover product also constantly increases, and the engine room cover performance of composites is required also to improve constantly.Shortcomings such as early stage adopt engine room cover that hand paste technology makes because low, the unstable product quality of properties of product, environmental pollution is big, and the big and working condition of labour intensity is abominable will progressively be withdrawn from the market.And advantage such as the resin vacuum guiding and forming technique has that properties of product are good, constant product quality, environmental pollution is little and working condition is good has manifested its technical advantage.Though its outer surface of engine room cover goods (lower surface) that the vacuum introducing technology is made is owing to have mould and the gel coat assurance, its surface can reach mirror effect, but inner surface (upper surface) is owing to will adopt water conservancy diversion net or permeable medium in technology, though it is much smooth that handicraft is stuck with paste than hand in its surface, but comparatively coarse.
Water conservancy diversion net or permeable medium can promptly be diffused into resin the surface of goods in technology, thereby finish the impregnation process of resin to the shop layer quickly.But simultaneously because permeable medium or water conservancy diversion net to the compression of product surface, make product surface form coarse surface.Because the engine room cover goods are increasing, the present length of some hood goods reaches more than the 12m, and width reaches more than the 4m, highly reaches more than the 1m, big surface like this, if require any surface finish, then the workload of grinding and buffing will be very big.Owing to adopt permeable medium, also to adopt release cloth in addition, in permeable medium and release cloth enrichment a large amount of resins, cause waste of material, these all cause the raising of production cost.
Summary of the invention
The vacuum forming manufacture method that the purpose of this invention is to provide a kind of wind-power engine room cap assembly of tool smooth finish surface.
In order to achieve the above object, technical scheme of the present invention has provided a kind of vacuum introduction manufacture method of engine room cover of tool smooth finish surface, the steps include:
Step 1, preparation mould are cleaned out die surface, and at least releasing agent of spraying also dries fully subsequently;
Step 2, product material shop layer size and shop layer thickness in accordance with regulations is laid on the mould of handling well by step 1;
Step 5, coat with vacuum film, and around the sealing, last resin is gone into by import, unnecessary resin is by exporting out;
It is characterized in that between step 2 and step 5, having
Step 3, on product material shop layer the high infiltration of lay fabric;
Step 4, on height infiltration fabric, place unsteady patrix with smooth finish surface.
Further, the unsteady patrix described in the step 4 adopts hard or flexible material to make, or adopts thin-film material to make.
High infiltration fabric can substitute water conservancy diversion net or permeable medium, makes resin to soak in the layer of shop quickly.Between unsteady patrix and goods, can form one deck resin-rich layer as thin as a wafer, not only can form protective effect, and make any surface finish such as minute surface goods.After formed product, throw off unsteady patrix, high infiltration fabric is then stayed in the product.
Advantage of the present invention is: can not adopt permeable medium to finish the vacuum introducing technology, and obtain the bright and clean hood goods in tool two sides, obviously reduce manufacturing cost.
