本考案は、ポリオレフイン発泡体等の成形用金
型に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mold for molding polyolefin foam and the like.
ポリオレフイン発泡体等の成形用金型として
は、種々の金型が提案されている。例えば、特開
昭57−191029号公報には、外表面に熱媒の流路を
設けた金型が記載されている。
Various molds have been proposed as molds for molding polyolefin foams and the like. For example, Japanese Unexamined Patent Publication No. 191029/1983 describes a mold having a heat medium flow path on its outer surface.
このような発泡体の加熱発泡に用いられる金型
としては、第２図に示すような金型が用いられて
いる。すなわち、密閉金型中で予備加熱して得ら
れた一次発泡体ａを、その底面及び周囲に熱媒流
路ｃが固着された箱状の金枠ｂに入れ、これらを
複数個積み重ねた状態で固定し、熱媒流路ｃにス
チームを通し、仕込んだ一次発泡体ａを加熱して
金枠ｂ内一杯に膨張させる。 As a mold used for heating and foaming such a foam, a mold as shown in FIG. 2 is used. That is, a primary foam a obtained by preheating in a closed mold is placed in a box-shaped metal frame b with a heat medium flow path c fixed to the bottom and around the mold, and a plurality of these are stacked. , and steam is passed through the heating medium flow path c to heat the charged primary foam a and expand it to the full extent inside the metal frame b.
前記したような構造の金型の場合、熱媒流路が
金枠ｂに溶接によつて固着されているので、得ら
れる発泡体の厚さを変更するためには、金型全体
をこうかんしなければならず、経済性の点で問題
があつた。
In the case of a mold having the structure described above, the heat medium flow path is fixed to the metal frame b by welding, so in order to change the thickness of the resulting foam, the entire mold must be changed. This posed a problem in terms of economy.
従つて、本考案の目的は、上記のような欠点を
解消し、経済性に優れた発泡体の成形用金型を提
供することにある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks and provide a mold for molding a foam that is highly economical.
本考案の発泡体成形用金型は、上記目的を達成
するため、熱媒体流路が設けられた平板が、矩形
状の金枠の上蓋に固着されるとともに、該金枠の
外側面に設けられた突出部に、脱着自在に取り付
けられていることを特徴とするものである。
In order to achieve the above object, the foam molding mold of the present invention has a flat plate provided with a heat medium flow path fixed to the upper lid of a rectangular metal frame and provided on the outer surface of the metal frame. It is characterized in that it is removably attached to the protruding portion.
このような構成において、熱媒流路を交換する
ことなく、金枠を交換するだけで、得られる発泡
体の寸法を容易に変更できる。 In such a configuration, the dimensions of the resulting foam can be easily changed by simply replacing the metal frame without replacing the heat medium flow path.
以下、添付図面に示す実施例を説明しつつ、本
考案について具体的に説明する。
EMBODIMENT OF THE INVENTION Hereinafter, the present invention will be described in detail while explaining embodiments shown in the accompanying drawings.

等で固定されている。 FIG. 1 is a sectional view showing an embodiment of a mold for molding a foam according to the present invention. A top cover 2 is placed on top of the rectangular metal frame 1, but the contact surface 3 is not fixed and is removable. The flat plate 4 is fixed to the upper lid 2. On top of the flat plate 4 is a triangular pipe 5.
are fixed to form a heat medium flow path 6. The flat plate 4 is provided with a protrusion 7, a protrusion 8 provided on the outer surface of the metal frame 1, and a bolt/nut 9.
etc. is fixed.
なお、熱媒流路５は、図示するような形状のパ
イプにより構成することに限定されるものではな
く、他の形状の熱媒配管により構成してもよく、
また適当な他のヒーターを用いてもよい。 Note that the heat medium flow path 5 is not limited to being formed by a pipe having the shape shown in the figure, but may be formed by a heat medium piping having another shape.
Other suitable heaters may also be used.
本考案の金型を実際に使用するときは、上蓋２
の上にヒーター及びカバープレートを設けたもの
を複数個積層して使用する。 When actually using the mold of this invention, the upper lid 2
A heater and a cover plate are provided on top of each other, and multiple units are stacked and used.
本考案の金型で、得られる発泡体の寸法を変更
しようとするときは、ボルト・ナツト９をはず
し、寸法の違う金枠と交換し、再びボルト・ナツ
ト９で固定すれば良い。熱媒流路等は、交換する
ことなく、そのまま使用でき、経済的に非常に優
れている。
When changing the dimensions of the foam obtained using the mold of the present invention, the bolts and nuts 9 can be removed, replaced with a metal frame of a different size, and then fixed again with the bolts and nuts 9. The heat medium flow path etc. can be used as is without being replaced, which is very economical.
