本発明はインジエクシヨンスキーの製造方法の
改善に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for manufacturing an injection ski.
従来よりインジエクシヨンスキーの製法には、

成樹脂を射出注入してインジエクシヨンスキーを
製造する方法が知られている。 Traditionally, the manufacturing method of Injiexion skis includes:
For example, as shown in FIG. 2, a lower surface component 8 consisting of a sliding surface material 5, a steel edge 6, etc. is attached to the lower mold 3.
Next, an upper surface component 11 consisting of a fiber-reinforced plastic plate 9 and an upper surface material 10 bonded in advance is placed in the notch 4 provided in the lower mold 3,
There is a known method of manufacturing an injection ski by injecting a foamed synthetic resin into a hollow portion 12 formed by placing an upper mold 2 thereon.
しかし、この方法では次のような欠点を有して
いた。 However, this method had the following drawbacks.
即ち、下金型３の切欠部４に上面構成部材１１
を配置する際において、上面構成部材１１に剛性

た。 That is, the upper surface component 11 is placed in the notch 4 of the lower mold 3.
When arranging the upper surface component 11, if a material with low rigidity is used, it will easily bend due to its own weight, so if the foamed synthetic resin is injected as it is, the resin will wrap around the bent part. ,
The result was a product with no commercial value, and the yield was extremely poor. For this reason, a method is used to prevent deflection due to its own weight by using a highly rigid and stiff member for the upper surface component 11, but the index ski manufactured by this method has high rigidity as a whole. This made it unsuitable as a ski for beginners and intermediates. Furthermore, the fiber-reinforced plastic plate and top material constituting the top component 11 must be preformed using adhesive, which is time-consuming and time-consuming.
This inevitably led to problems such as high prices.
本発明はかかる欠点に鑑み、生産性が良好で、
かつ初級者や中級者向きの剛性の柔らかい軽量で

スキーの製造方法である。 To explain the present invention based on the drawings, as shown in FIGS. 3 to 6, a ski molding lower mold 15
A lower surface component 19 made of a sliding surface material 16, a steel edge 17, etc. is disposed on the lower mold 15, and a support member 20 for supporting the upper surface component 22 is installed in the width direction of the lower mold 15. A fiber-reinforced plastic material 13 having an appropriate gap 14 is placed on top, and an upper surface material 21 is further placed to form an upper surface component 22. Next, after placing an upper mold 23, a lower surface component 19 is formed. This method of manufacturing an injection ski is characterized in that a foamed synthetic resin 25 is injected into a hollow portion 24 formed by the upper surface component 22 and the foamed synthetic resin 25 is foamed and hardened to integrally mold the ski at the same time.
以上本発明のインジエクシヨンスキーの製造方

うに、上面構成部材をあらかじめ、予備成形して
おく必要性はなくなり、工程が簡略化できるので
コストダウンが可能となる。 As described above, in the method for manufacturing an injection ski of the present invention, an appropriate gap 1 as shown in FIG.
4, the foamed synthetic resin fills the gaps 14 by injecting the foamed synthetic resin after placing it in the mold.
The fiber-reinforced plastic material 13 and the top material 21 are integrally molded during foaming and curing. Therefore, unlike in the past, there is no need to preform the upper surface constituent member in advance, and the process can be simplified and costs can be reduced.
又、本発明によるインジエクシヨンスキーの製
造方法においては、下金型に上面構成部材を支持

キーを供給することができるものである。 In addition, in the method for manufacturing an injection ski according to the present invention, since the support member 20 for supporting the upper surface component is installed on the lower mold, the deflection due to its own weight can be prevented without increasing the rigidity of the upper surface component. Since this can be prevented, the stiffness of the ski itself can be made softer, making it possible to supply skis suitable for beginners and intermediate skiers.

It is also possible to use objects.
更に、実施例図面は省略したが、上面構成部材
だけでなく、下面構成部材用としても適宜な間隙
１４を有する繊維強化プラスチツク材１３を使用

なる。 Further, although the drawings of the embodiments are omitted, by using the fiber reinforced plastic material 13 having an appropriate gap 14 not only for the upper surface component but also for the lower surface component, it is possible to integrally mold the lower surface component.
そのほか、本発明に使用する上面構成部材を支
