を正確に保持することができる型締装置に関する
ものである。[Detailed description of the invention] This invention is designed to prevent the mold mounting surface of each plate from deforming by applying strong clamping force to the injection molding machine during use. The present invention relates to a mold clamping device that can accurately hold a molded product forming part between the molds by making proper planar contact with the mold.
プラスチツク、ゴム、セラミツクなどの射出成
形機の型締装置は、高圧で射出充填される金型を
強固に締付けておくという重要な役割を持つてい
る。 The mold clamping device of an injection molding machine for plastic, rubber, ceramic, etc. has an important role of firmly clamping the mold that is injected and filled at high pressure.
そして型締装置には、高精度に加工された金型
を正しく保持するために、その固定盤と可動盤と
の平行度は勿論のこと、各取付面の平面度も厳密
に製作することが要求される。 In order to correctly hold a mold that has been machined with high precision, the mold clamping device must be manufactured not only to ensure the parallelism of the fixed plate and movable plate, but also to ensure the flatness of each mounting surface. required.
これを従来装置を示す第１図について詳しく説
明すると、固定金型６を取付ける固定盤１の中央
には、固定金型６と可動金型７との間で形成され
る成形品形成部８に樹脂を射出するための射出装
置（図示していない）のシリンダとかノズルを挿
入するすり鉢状の孔９が設けられている。 To explain this in detail with reference to FIG. 1 showing the conventional device, in the center of the fixed platen 1 on which the fixed mold 6 is attached, there is a molded product forming part 8 formed between the fixed mold 6 and the movable mold 7. A mortar-shaped hole 9 is provided into which a cylinder or nozzle of an injection device (not shown) for injecting resin is inserted.
また前記可動金型７を取付ける可動盤５には、
成形品８を突出すためのエジエクトプレート１０
を作動させる突出し装置１１を設けるため、これ
にも溝孔１３を設けている。 In addition, the movable platen 5 to which the movable mold 7 is attached includes:
Eject plate 10 for ejecting molded product 8
This is also provided with a slot 13 in order to provide an ejection device 11 for actuating the .
したがつて、型締シリンダ２を作動し、型締ピ
ストン４で両金型６，７を大きな型締力で締付け
ると、固定盤１および可動盤５に微妙な変形が生
じることを防止することはできない。 Therefore, when the mold clamping cylinder 2 is operated and the mold clamping piston 4 clamps both molds 6 and 7 with a large mold clamping force, it is possible to prevent the fixed platen 1 and the movable platen 5 from being slightly deformed. I can't.
固定盤１のすり鉢状の孔９とか可動盤５の溝孔
１３は、応力面から考えても、厳しい状態の箇所
である盤中央部にあるので、同盤１，５はより変
形し易い状態である。この型取付面の変形は成形
品形成部８の形状を変えることになり、精密な成
形品の形成上これは致命的な欠陥となるし、また
極端な場合は鋳張りなどの生じることにもなる。 The cone-shaped hole 9 in the fixed platen 1 and the slot 13 in the movable platen 5 are located in the center of the platen, which is a severe area in terms of stress, and therefore the platen 1, 5 are more likely to deform. This deformation of the die mounting surface changes the shape of the molded product forming portion 8, which can be a fatal defect in forming precision molded products and, in extreme cases, can cause overcasting.
このような欠点を防止するため、従来は、固定
盤１可動盤５の厚みを大きくし、極力変形を押え
るとともに、若干の変形が、金型の成形品形成部
８に影響を及ぱさないように金型そのものをも強
固なものにすることで、これに対処していた。 In order to prevent such defects, conventionally, the thickness of the fixed platen 1 and the movable platen 5 is increased to suppress deformation as much as possible, and to prevent slight deformation from affecting the molded product forming part 8 of the mold. This was addressed by making the mold itself stronger.
しかし、これらの対策は、何れも、型締装置全
体を強固にすることが必要であり、装置全体の重
量増加となり、価格的にも、エネルギー消費面か
らも好ましい結果を得ることは難しかつた。 However, all of these measures require the entire mold clamping device to be made stronger, which increases the weight of the entire device, making it difficult to obtain favorable results in terms of cost and energy consumption. .
本考案は、このような従来装置の欠点を解消
し、高性能であつて、しかも低価格の型締装置を
得んとするものであつて、固定盤１あるいは可動
盤５の各型取付面に凸面を形成してその目的を達
成せんとするものである。 The present invention aims to eliminate the drawbacks of the conventional devices and provide a mold clamping device with high performance and low cost. The purpose is to achieve this purpose by forming a convex surface on the surface.
その構成ならびに作用を図面について説明す
る。 Its structure and operation will be explained with reference to the drawings.
固定盤１の型取付面１′に、すり鉢状の孔９を
中心として中央部を高さ△ｌだけ高くし型取付面
１′の外周に向つて緩やかに傾斜した凸面１４を
形成する。凸面１４は凸曲面あるいは円錐状に形
成するのがよい。 A convex surface 14 is formed on the mold mounting surface 1' of the fixed platen 1, with the central part raised by a height Δl around the mortar-shaped hole 9, and gently inclined toward the outer periphery of the mold mounting surface 1'. The convex surface 14 is preferably formed into a convex curved surface or a conical shape.
可動盤５の型取付面５′にも、成形品の突出し
装置を設けるために溝孔１３を中心として、中央
部を高さ△l′だけ高くし型取付面５′の外周に向
つて緩やかに傾斜した凸面１４′を形成する。 Also on the mold mounting surface 5' of the movable platen 5, in order to provide a device for ejecting the molded product, the central part is raised by a height △l' with the slot 13 as the center, and the height is gradually increased toward the outer periphery of the mold mounting surface 5'. A convex surface 14' is formed.
前記高さ△ｌおよび△l′は、予想される各盤
１，５の変形量を補うように予め定めるものであ
るが、一般には、固定盤１の方が可動盤５より変
形量が大きいので、固定盤１の凸面１４の高さ△
ｌは可動盤５の凸面１４′の高さ△l′より高くす
る。 The heights △l and △l' are predetermined to compensate for the expected amount of deformation of each platen 1 and 5, but in general, the amount of deformation of the fixed platen 1 is larger than that of the movable platen 5. Therefore, the height of the convex surface 14 of the fixed platen 1 is △
l is set higher than the height Δl' of the convex surface 14' of the movable platen 5.
第５図および第６図において、１２はスペーサ
ーで、その表面に凸面１４を形成し、このスペー
サー１２は固定盤１に、各種の高さ△ｌのものを
取換え可能に取付ける。このことは、可動盤５に
おいても同様である。 In FIGS. 5 and 6, numeral 12 denotes a spacer having a convex surface 14 formed on its surface, and this spacer 12 is attached to the stationary plate 1 so as to be replaceable in various heights Δl. This also applies to the movable platen 5.
第６図ロのスペーサー１２は、同図イのスペー
サー１２の凸面１４の高さ△l1と異なつた高さ△
l2を有するものであつて、このように異なつた高
さ△l1，△l2を有するスペーサー１２を数種類準
備しておいて、使用金型に応じ最適の高さ△ｌを
選定して使用するようにする。 The spacer 12 shown in FIG.
Prepare several kinds of spacers 12 having different heights △l 1 and △l 2 , and select the optimum height △l according to the mold used. Let it be used.
そして強い型締力をもつて型締を行つた場合、
各盤１，５の凸面１４，１４′は各盤の変形量を
丁度補うことになつて各金型６，７で形成される
成形品形成部８の形状は変化しない。 And when the mold is clamped with a strong clamping force,
The convex surfaces 14, 14' of the plates 1, 5 exactly compensate for the amount of deformation of each plate, so that the shape of the molded product forming portion 8 formed by each of the dies 6, 7 does not change.
その効果を説明する。 The effect will be explained.
本考案においては、型締の際生じる固定盤およ

型取付面に前以つて凸面を形成しているので、型
締した状態では金型取付面と金型とが、正しく、
隙間なく、平面的に接触することになつて均一な
型締力を得ることができる。 In this invention, in anticipation of the amount of deformation of the fixed platen and the movable platen that will occur during mold clamping, a convex surface is formed on the mold mounting surface of the platen in advance, so that when the mold is clamped, the Make sure that the mold mounting surface and the mold are connected correctly.
Since there is no gap and there is a two-dimensional contact, a uniform mold clamping force can be obtained.
したがつて金型に無理な変形がなく成形品形成
部の形状は常に正確となる。 Therefore, there is no unreasonable deformation of the mold, and the shape of the molded product forming part is always accurate.

ようなことがなくなり、低価格であつてその取扱
いのし易い装置を得ることができる。 In addition, unlike conventional equipment, it is no longer necessary to make the fixed plate, movable plate, and both molds strong in order to minimize deformation, which also increases the weight and cost of the equipment. This eliminates such problems, and it is possible to obtain a device that is inexpensive and easy to handle.
