【考案の詳細な説明】
本考案は、主型と入子型とからなるダイカスト
機または樹脂成型機における金型の改良に関する
ものである。[Detailed Description of the Invention] The present invention relates to an improvement of a mold in a die-casting machine or a resin molding machine, which consists of a main mold and a nested mold.
この種金型は、鋳造または成形中常に所要の温
度を維持させる必要あり、特に入子型の冷過ぎは
鋳造または成形製品の不良をもたらす。 This type of mold needs to maintain a required temperature during casting or molding, and in particular, if the nesting mold is too cold, the cast or molded product will be defective.
そこで、従来では主型と入子型との間にアスベ
スト製の断熱材を介在させて金型、特に入子型の
冷過ぎを防いだ例があつた。しかし、アスベスト
製の断熱材は型締力によつて容易につぶれてしま
い、金型（固定型と可動型）の型合せの精度が非
常に出し難い不便欠点があつた。 Therefore, in the past, there was an example of interposing an asbestos insulating material between the main mold and the nesting mold to prevent the mold, especially the nesting mold, from getting too cold. However, the insulating material made of asbestos was easily crushed by mold clamping force, making it difficult to accurately match the molds (fixed mold and movable mold).
本考案はこの様な従来の不便欠点に鑑み、主型
又は入子型の型合せ面に凹部又は凸部を形成する
ことにより、アスベスト製の断熱材を使用せずと
も、入子型の冷過ぎを確実に防止でき、しかも固
定型と可動型とを精度良く型合せすることが出来
る金型を提供せんとするものである。 In view of these conventional inconveniences, the present invention is designed to cool the nested mold without using asbestos heat insulating material by forming concave or convex portions on the mating surfaces of the main mold or the nested mold. It is an object of the present invention to provide a mold that can reliably prevent overflow and also enable accurate mold matching of a fixed mold and a movable mold.
以下、本考案実施の一例を図面に基づいて説明
する。 An example of implementing the present invention will be described below based on the drawings.
主型１はその中央に正面四角形状の嵌合凹部２
を形成し、その嵌合凹部２内に入子型３を嵌合セ
ツトする。 The main mold 1 has a rectangular fitting recess 2 in its center.
is formed, and the nesting mold 3 is fitted and set in the fitting recess 2.
入子型３は主型１の嵌合凹部２内に緊密状に嵌
合し得る大きさの四角ブロツク形状に成形し、そ
の一面にキヤビテイ部４を形成する。 The nesting mold 3 is formed into a rectangular block shape large enough to fit tightly into the fitting recess 2 of the main mold 1, and a cavity portion 4 is formed on one surface thereof.
而して、主型１又は入子型３の型合せ面１ａ，
３ａに凹部５又は凸部６を形成して、前記夫々の
型合せ面１ａ，３ａの間に空気断熱層を構成す
る。 Therefore, the mold mating surface 1a of the main mold 1 or the nested mold 3,
A concave portion 5 or a convex portion 6 is formed in 3a to constitute an air heat insulating layer between the respective mold matching surfaces 1a and 3a.
型合せ面１ａ，３ａとは主型１にあつては嵌合
凹部２を構成する五つの面を言い、入子型３にあ
つてはキヤビテイ部４を除く五つの面を言い、こ
れら型合せ面１ａ又は３ａの略全域にわたつて凹
部５又は凸部６を点在状に形成することにより、
入子型３のキヤビテイ部４を除く五つの面を囲む
空気断熱層７が形成される。 The mold matching surfaces 1a and 3a refer to the five surfaces forming the fitting recess 2 in the case of the main mold 1, and the five surfaces excluding the cavity part 4 in the case of the nesting mold 3. By forming the concave portions 5 or the convex portions 6 in a scattered manner over substantially the entire area of the surface 1a or 3a,
An air heat insulating layer 7 is formed that surrounds five sides of the nested mold 3 except for the cavity portion 4.
凹部５とは型合せ面１ａ，３ａを適宜深さに抉
つた穴又は溝を言い、凸部６とは型合せ面１ａ，
３ａに適宜高さに突設させた突起又は突条を言
う。 The concave portion 5 refers to a hole or groove cut to an appropriate depth in the mold matching surfaces 1a, 3a, and the convex portion 6 refers to a hole or groove cut into the mold matching surfaces 1a, 3a.
It refers to a protrusion or protrusion provided at an appropriate height on 3a.
第１図及び第２図に示す実施例は、入子型３の
型合せ面３ａ略全域にわたつて穴形状の凹部５を
適宜点在状に形成したものであるが、穴形状に替
えて溝形状の凹部でも良いし、また凹部５に替え
て凸部６を形成するようにしても良い。 In the embodiment shown in FIGS. 1 and 2, hole-shaped recesses 5 are formed at appropriate intervals over substantially the entire area of the mold mating surface 3a of the nesting mold 3. A groove-shaped recess may be used, or a protrusion 6 may be formed in place of the recess 5.
又、第３図及び第４図に示す実施例は、主型１
の型合せ面１ａ略全域にわたつて多数の突条を格
子形状に組合わせて凸部６を点在状に形成したも
のであるが、凸部６は数条形成しても良いし、ま
た突条に替えて突起でも良いし、更に凸部６に替
えて凹部５を形成するようにしても良い。 In addition, the embodiment shown in FIGS. 3 and 4 is based on the main mold 1.
The protrusions 6 are formed in a dotted manner by combining a large number of protrusions in a lattice shape over substantially the entire area of the mold matching surface 1a, but the protrusions 6 may be formed in several stripes, or Protrusions may be used instead of the protrusions, and recesses 5 may be formed instead of the protrusions 6.
本考案は以上説明したように構成したものであ
るから、主型の型合せ面と入子型の型合せ面同士
の接触面積を減少させて入子型の熱が主型を伝つ
て放散することを極力抑えると共に、空気断熱層
が入子型を囲むことによる保温効果によつて、入
子型の冷過ぎを防いで鋳造または成形製品の不良
を防止することができる。 Since the present invention is configured as explained above, the contact area between the mold mating surfaces of the main mold and the mold mating surfaces of the nested mold is reduced, and the heat of the nested mold is transmitted through the main mold and dissipated. In addition to suppressing this as much as possible, the heat insulating effect produced by surrounding the nested mold with the air heat insulating layer prevents the nested mold from becoming too cold, thereby preventing defects in the cast or molded product.
しかも、従来のようにアスベスト製の断熱材を
使用した場合と異なり、型合せ面に直接凹部又は
凸部を形成したものであるから、固定型と可動型
とを精度良く型合せすることが出来、優れた製品
を鋳造することが出来る。 Moreover, unlike the conventional case where asbestos insulation material is used, since the concave or convex portions are formed directly on the mold matching surface, it is possible to precisely match the fixed mold and the movable mold. , can cast excellent products.
よつて、所期の目的を達成し得る。 Therefore, the intended purpose can be achieved.
