Description

【考案の詳細な説明】 プラスチック箱等の嵌合わせ器具には、その弾力性を利
用した俗称パラチン止めなどと呼ばれる凹凸留め方式が
ある。[Detailed description of the invention] For fitting devices such as plastic boxes, there is a concave-convex fastening method, commonly known as a pachinko fastening, which takes advantage of its elasticity.

ところが、この従来方式は製作段階においてスライドコ
ア一方法、突出コアーピン方法などの水平方向排除の脱
型手段が要求されるため、金型の工作手間、費用が嵩み
また型破損度合が大でその修理も困難であるなどの難点
があった。However, this conventional method requires a demolding method for horizontal removal such as a slide core method or a protruding core pin method at the manufacturing stage, which increases the labor and cost of mold machining and increases the degree of mold damage. It also had some drawbacks, such as being difficult to repair.

本案は従来のこのような実情に鑑みてなされたもので、
製作段階における脱型が垂直運動のみで行えるとともに
凹凸留め方式としてもその差止め、外しか軽快に行える
手段を提供するものである。This proposal was made in view of the existing circumstances,
The present invention provides a means for demolding at the manufacturing stage using only vertical movement, and also as a concave-convex fastening method, which allows easy fastening and removal.

In the figure, B is the receiving side, and the side wall 1 is provided with a vertical groove 2 deeper than the thickness of the side wall 1 with a slight upper edge 1a left, and both sides of the upper part of the inner protruding wall 3 within the rod-shaped groove 2. Cuts 3a, 3a are provided in the.

図）。Then, insert the insertion piece 5 into the gap between the inner protruding wall 3 with the notches 3a on both sides □ and the upper edge 1a of the side wall 1 by pushing open the inner protruding wall portion with the notches 3a, and inserting the insert piece 5. The hook step part 6 is locked and fastened to the upper edge part 1a (Figs. 3 and 4).
figure).

外す場合には第３図、第４図の状態から差込片５を内方
へ僅に押せば切込み３ａを入れた内側突出壁部分が内側
へ開くから引掛段部６が上縁部１ａを容易に外れて上方
へ抜ける。To remove it, press the insert piece 5 slightly inward from the state shown in Figures 3 and 4, and the inner protruding wall portion with the notch 3a will open inward, allowing the hook step 6 to touch the upper edge 1a. It comes off easily and goes upwards.

本案装置は以上のようで、製作面では、受入側Ｂも差込

が゛ある。The proposed device is as described above, and in terms of manufacturing, the mold comes out only by vertical movement on both the receiving side B and the insertion side A due to their configuration, so the mold is extremely easy to work and inexpensive. This has advantages such as less mold damage and greater fractionation when forming molded products, and as for the equipment itself, as mentioned above, it is easy to attach and remove, makes less noise, and has great ease of assembly. It has many advantages, such as being able to visually tell where it is fastened when it is removed.

本案装置を施すと嵌合わせ器具の内側に若干突出部か゛
また外側な凹欠部ができるが゛、その点において支障が
