た。However, when observing the surface of these in-mold foamed products,
There is a grain boundary pattern that occurs when foamed particles expand and fuse together, and this pattern causes these in-mold foam molded products to lose their high-quality appearance, and their use is limited to popular or disposable products. there were. The phenomenon in which such a grain boundary pattern occurs is inevitably caused by the low foam expansion properties of polyolefin resins and poor mold reproducibility.

８号公報）。To solve this problem, a geometric pattern consisting of uneven stripes with a pitch equal to or narrower than the unit diameter of the grain boundary pattern on the surface of the material is applied in advance to the visible surface of the molded container. By providing the geometric pattern on the inner surface of the mold, the reflection from the uneven surface of the molded product is visually highlighted, and the grain boundary pattern of the expanded particles is mixed and buried in the shadow. , a technique has been disclosed in which the surface of a resin molded product appears uniformly and beautifully finished so that it cannot be distinguished from the molded product made of foamed resin particle material (Utility Model Application Publication No. 63-10872).

いない。(Problem to be Solved by the Invention) However, in such in-mold foam molding, a slit with a diameter of 0.1 to 0.3 mm is provided as a steam hole for sending heating steam into the mold cavity. A core vent of 5 to 10 mm is embedded in the mold, and in the mold of the above-mentioned Japanese Utility Model Publication No. 63-108728, no treatment was taken for this core vent, and the molded product was left with traces of steam holes here and there. The problem that the grain boundary pattern of the original expanded particles becomes noticeable depending on the viewing angle and the problem that the appearance of the molded product is spoiled has not yet been solved.

にある。The present invention has been made in view of the above points, and its purpose is to:
To provide a mold for polyolefin resin foam molding which not only hides the grain boundary pattern of expanded particles but also allows in-mold foam molding without leaving any traces of steam holes on the surface of the molded product.

。According to the present invention, in a mold for manufacturing a foam molded article by filling a mold cavity formed by a core mold and a cavity mold with polyolefin resin foam particles having an average particle diameter of 2n+m to 6 mm, The mold has a large number of small-diameter steam holes, the diameter of the steam holes is 0.5 mm to 1.2 mm, the pitch of the steam holes is 5 mm to 20 mm, and the porosity of the i-pores to the mold surface is 0. .5% to 4%, and a mold for polyolefin resin foam molding is provided, which is characterized in that the inner surface of the mold is provided with a textured pattern.
本発明に用いられるポリオレフィン系樹脂発泡粒子とし

リオレフィン系樹脂発泡粒子は、平均粒子径２ｍｍ〜６
ｍｍのものが使用される。２ｍｍ未満では小さすぎて
発泡能が低く、発泡粒子間に窪みが発生し、発泡粒子相
互の融着性が悪くなったりまた外観上も好ましくない。The expanded polyolefin resin particles used in the present invention include polyethylene, polypropylene, copolymers thereof, and copolymers with other monomers copolymerizable with these.
Expanded particles obtained from mixtures of these and the like are included. The polyolefin resin foam particles have an average particle diameter of 2 mm to 6
mm is used. If it is less than 2 mm, it is too small and the foaming ability is low, depressions are formed between the foamed particles, the fusion properties between the foamed particles become poor, and the appearance is also unfavorable.
また、６Ｍを超えると成形体表面に樹脂粒子の形状に盛
り上がり外観が悪くなり好ましくない。Moreover, if it exceeds 6M, the surface of the molded product will bulge in the shape of resin particles, which will deteriorate the appearance, which is not preferable.
本発明の金型はコア金型とキャビティー金型とで構成さ

いる。そして、この蒸気孔の直径は０．５ｍｍ〜１．２
ｍｍである。０．５ ｍｍ未満では加熱蒸気の供給が困
難になり、１．２ｍｍを超えると蒸気孔の跡が目立ち好
ましくない。The mold of the present invention is composed of a core mold and a cavity mold, and these molds are provided with a large number of small-diameter steam holes. The diameter of this steam hole is 0.5 mm to 1.2 mm.
It is mm. If it is less than 0.5 mm, it will be difficult to supply heating steam, and if it exceeds 1.2 mm, the marks of the steam holes will be noticeable, which is not preferable.
蒸気孔間のピッチは５＋＋＋ｍ〜２０ｍｍである。５胴
未満では金型に開ける孔の数が多いために金型製作に多
大の労力と費用を要することとなり、２０ｍｍを超える
と蒸気孔の数が少ないために蒸気加熱が困難になる。The pitch between steam holes is 5+++ m to 20 mm. If the diameter is less than 5 mm, the number of holes to be drilled in the mold will be large, requiring a great deal of labor and expense to manufacture the mold, and if the diameter exceeds 20 mm, the number of steam holes will be small, making steam heating difficult.
また、蒸気孔の金型面に対する開孔率は０．５％〜４％
である。０．５％未満ではポリオレフィン系樹脂発泡粒

える開孔率にしても開孔率を増やしただけの効果がなく
、経済的な利益もない。In addition, the porosity of the steam hole relative to the mold surface is 0.5% to 4%.
It is. If it is less than 0.5%, the amount of steam necessary for foaming and fusing the expanded polyolefin resin particles cannot be secured, and even if the porosity exceeds 4%, it will not have the effect of increasing the porosity, making it economical. There is no profit.
本発明の金型を構成する材質としては、アルミニウム系
金属が加工性、軽量性、伝熱性等の点で好ましい。As the material constituting the mold of the present invention, aluminum-based metal is preferable in terms of workability, lightness, heat conductivity, and the like.
本発明の金型内面にはシボ模様が付されている。The inner surface of the mold of the present invention has a grain pattern.
シボ模様としては、丸状、格子状、革目状、ダイヤカッ
ト状等の凹凸模様が好ましい。本発明の目的には革目状
のシボ模様が特に好ましい。As the grain pattern, an uneven pattern such as a round shape, a lattice shape, a leather grain shape, a diamond cut shape, etc. is preferable. For the purpose of the present invention, a leather grain pattern is particularly preferred.
金型にこのようなシボ模様を付すには、金型のエツチン
グによる方法、シボ模様の付いたパンチングメタルの金
型表面への貼り付けによる方法等により行われる。Such a textured pattern can be applied to a mold by etching the mold, by pasting punched metal with a textured pattern on the surface of the mold, or the like.

金型表面を洗浄、乾燥する。In the etching method, for example, a photosensitive resin layer is formed on the mold surface by pasting a photosensitive resin sheet or coating the photosensitive resin, and then a mask with a pattern is attached and exposed. Then, the uncured portion is dissolved and removed. Next, a chemical solution is applied through the cured resin layer to etch the mold surface. After etching, peel off the cured resin film,
Clean and dry the mold surface.

いように目止めを行なってもよい。Here, the above-mentioned etching may be performed either before or after forming the steam holes in the mold. When etching is performed after drilling the steam hole, the hole may be sealed to prevent chemical liquid from entering the hole.
また、パンチングメタルを貼り付ける場合は、パンチン

し、金型とパンチングメタルにそれぞれ孔を開けておき
、孔の位置を合せるように貼り付けてもよい。In addition, when pasting punching metal, you can create a steam hole by pasting the punching metal and then drilling a hole that passes through the punching metal and the mold body, or you can create a hole in the mold and punching metal separately. You may also attach it so that the holes are aligned.

Therefore, the traces of steam holes on the surface of the foamed molded product are difficult to distinguish, and furthermore, since the inner surface of the mold has a grain pattern, the pattern of the particle interface of the foamed particles can be seen on the surface of the foamed molded product. In addition to being hidden, the marks of the steam holes become even more difficult to see due to the grain pattern. Therefore, it becomes possible to obtain a foamed molded product having a beautiful appearance with a high-class feel.
