Description

【考案の詳細な説明】（産業上の利用分野）この考案は、段階の踏み板等の板材前縁に合成
樹脂製縁部材を成形するための成形型に関する。[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a mold for forming a synthetic resin edge member on the front edge of a board such as a step board.

（従来技術）従来この種成形型として、第１図に示す如きも

１１を切断して製品を得るようにしていた。(How to use the conventional mold) The method of using the conventional mold 1 is as follows.
That is, the front part of the plate material 11 on which the protruding stripes 12 are formed is aligned and fitted into the opening 4 leaving a space 2 corresponding to the synthetic resin edge member 13, and then the mold 1 is inserted from above and below. Resin was press-fitted into the space 3 while being compressed, and after the resin had hardened, the plate material 11 was extracted from the mold 1, and the plate material 11 was cut at the position indicated by the dashed line in FIG. 1 to obtain a product. .

（従来技術の欠点）前記従来成形型１には以下の如き欠点があつ

１を上下から挟圧するので、板材１１と成形型１
との上下の間〓からは樹脂は漏れないが、両者の
左右の間〓からは樹脂が漏れるという欠点があつ
た。(Defects of the Prior Art) The conventional mold 1 had the following drawbacks. That is, when press-fitting the resin into the space 3, the mold 1 is pinched from above and below, so that the plate material 11 and the mold 1
There was a drawback that resin did not leak from between the top and bottom of the two, but it did leak from between the left and right of the two.

（考案の目的）この考案は上記欠点を解消するためになされた
ものであつて、板材と成形型との左右の間〓から
も樹脂が漏れることのない成形型を提供すること
を目的とするものである。(Purpose of the invention) This invention was made in order to eliminate the above-mentioned drawbacks, and the purpose is to provide a molding die that prevents resin from leaking even from the left and right spaces between the plate material and the molding die. It is something.

（実施例）以下にこの考案を第２図及び第３図に示す実施
例に基づいて説明する。(Example) This invention will be explained below based on the example shown in FIGS. 2 and 3.

なお、第１図に示す部材と同一の部材は同一の
符号で示す。キヤビテイー２の左右側部に、板材
１１の前面左右部が当接する段部５が形成されて
いる。板材１１に形成された凸条１２の左右端部
は切除されている。 Note that the same members as those shown in FIG. 1 are designated by the same reference numerals. Step portions 5 are formed on the left and right sides of the cavity 2, with which the front left and right portions of the plate material 11 abut. The left and right ends of the protrusions 12 formed on the plate material 11 are cut off.

実施例成形型１は、シリコン・合成ゴム等の可
撓性合成樹脂製である。 The mold 1 of the embodiment is made of flexible synthetic resin such as silicone or synthetic rubber.

（実施例の使用方法）前記成形型１の使用方法は以下の通りである。
即ち、板材１１の前部を開口４に整合嵌入し、板
材１１の前面左右部が段部５に当接するように、
板材１１を成形型１に向けて押し付けると共に、
成形型１を上下から挟圧して、空間３内に樹脂を
圧入し、樹脂が硬化した後板材１１を成形型１か
ら抜き出し、第３図の一点鎖線で示す位置にて板
材１１を切断して製品を得る。(How to use the embodiment) The method of using the mold 1 is as follows.
That is, the front part of the plate material 11 is aligned and fitted into the opening 4, and the front left and right parts of the plate material 11 are in contact with the step part 5.
While pressing the plate material 11 toward the mold 1,
The mold 1 is pressed from above and below to press fit resin into the space 3, and after the resin has hardened, the plate material 11 is extracted from the mold 1, and the plate material 11 is cut at the position shown by the dashed line in FIG. Get the product.

（考案の効果）この考案は、前記した如き構成によつて、以下
に記載の効果を奏するものである。(Effects of the invention) This invention achieves the effects described below by virtue of the configuration described above.

キヤビテイーの左右側部に、板材の前面左右部
が段部に当接する段部が形成されているので、板
材の前面左右部が段部に当接するように、板材を
成形型に向けて押し付けることにより、板材と成
形型との左右の間〓から樹脂が漏れるのを防止す
ることが出来る。 Steps are formed on the left and right sides of the cavity, where the front left and right sides of the plate abut against the steps, so press the plate toward the mold so that the front left and right sides of the plate come into contact with the steps. This can prevent resin from leaking from between the left and right sides of the plate material and the mold.
