Abstract

PURPOSE:To secure firmly a coating surface of a waterproofing paint to an air spoiler, by forming a coating surface of a waterproofing paint to an attaching surface of the air spoiler when the air spoiler is molded. CONSTITUTION:A mold by which an air spoiler 10 of a synthetic resin will be molded comprises a top force 6a, and a bottom force 6. The top force 6a is coated with a waterproofing paint 4a. Then, a bolt 5 and a reinforcing plate 3 are set to the top force 6a, and a skin 1 is set to the bottom force 6. A two- pack polyurethane resin 2a is injected onto the skin 1 and the top force 6a is secured onto the bottom force 6. By the reaction between the two liquids, the polyurethane resin 2a is allowed to foam, and the foamed urethane resin 2a, the skin 1 and the waterproofing paint 4a are joined together. When the molding is completed, the attaching surface of the air spoiler 10 where an opening 1a of the skin 1 is located will be covered with the coating surface of the waterproofing paint. The air spoiler 10 is positively covered with the coating surface 4 of the waterproofing paint.

Description

【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野〕 本発明は、エアスポイラ、特に、合成樹脂製のエアスポ
イラの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an air spoiler, and in particular to a method for manufacturing an air spoiler made of synthetic resin.

（従来の技術） 従来この種のエアスポイラは、空気抵抗、リヤ揚力を軽

。(Prior Art) Conventionally, this type of air spoiler has been attached to the trunk or the like at the back of an automobile in order to reduce air resistance and rear lift force.

The air spoiler 10 is fixed to a trunk or the like by a mounting bolt 5 embedded in the air spoiler 10 via a waterproof paint-type coating surface 4. Note that a reinforcing plate 3 attached to the bolt 5 is also buried within the air spoiler 1θ.

する。Such a synthetic resin air spoiler 10 has conventionally been manufactured by molding. That is, as shown in FIG. 5.6, first, the skin 1, which has been formed into a predetermined shape, is placed on the lower mold 11, and the bolts 5 and reinforcing plate 3 are set on the upper mold 12. Two-component polyurethane resin 2 in the epidermis 1
At the same time, the upper mold 12 is fixed on the lower mold 11.

At this stage of foaming and curing, the polyurethane resin 2a comes into close contact with the epidermis 1. When the polyurethane resin 2a is sufficiently cured and demolded, an air spoiler 10 having a predetermined shape is obtained.

The epidermis 1 has an opening 1a for inserting the device. Therefore, the skin 1 exists only on a portion of the mounting surface of the air spoiler IO. Therefore, after taking out the air spoiler 10 from the mold 11.12, in order to make the interior 2 made of foamed urethane resin waterproof, the air spoiler 1
However, the molded air spoiler 10 was coated with waterproof paint on the mounting surface of the mold 11.
A mold release agent is applied to the molding surfaces of the molds 11 and 12 so that they can be easily removed from the mold. For this reason, if the waterproof paint is coated immediately after demolding, the waterproof paint will peel off.For this reason, conventionally, the air spoiler 10 has been cleaned with trichlorethylene paper and then coated with the waterproof paint.

しかしながら、トリクロルエチレンでヘーパー洗浄して

った。However, it is difficult to completely remove the mold release agent even with Heper cleaning with trichlorethylene. Therefore, there was a problem in that it was not possible to reliably prevent the waterproof paint from peeling off.

そこで、本発明は、防水塗料の＠ＩＭ防止を確実とする
ことを、その技術的課題とする。Therefore, the technical objective of the present invention is to ensure @IM prevention of waterproof paint.

説明する。(Function) As a result, according to the method for manufacturing an air spoiler according to the present invention, the waterproof paint is also coated on the air spoiler during molding of the air spoiler. Therefore, the air spoiler is reliably coated with the waterproof paint without being affected by the mold release agent (Example) A preferred embodiment of the present invention will be described below with reference to the drawings.

The air spoiler 10 is composed of an interior 2 made of foamed urethane resin and a skin 1 made of vinyl chloride, and the mounting surface of the air spoiler 10 where the opening 1a of the skin 1 is located is covered with a coating surface made of waterproof paint. Therefore, the coating surface 4 made of waterproof paint is reliably coated on the air spoiler IO without being affected by the release agent applied to the molds 6a, 6.
