Description

本発明は、樹脂成型品、成形装置、成形方法及び金型に関するものである。   The present invention relates to a resin molded product, a molding apparatus, a molding method, and a mold.

例えば複数の樹脂を用いて成形された多色成形物では、ランナー部分で異なる樹脂が互いに接続されるものがある。特許文献１には、このような多色成形物を成形する成形装置が記載されている。特許文献１に記載された成形装置では、金型のランナー溝内に仕切り部材を設け、仕切り部材が、ランナー溝の一方から流れる１次成形樹脂の流れを阻止し、１次成形樹脂が硬化した後、ランナー溝の他方から１次成形樹脂とは異なる２次成形樹脂が流される。このとき、２次成形樹脂の流圧により仕切り部材がランナー溝外に押し下げられることで、仕切り部材があった位置に２次成形樹脂が流れ込み、１次成形樹脂と溶着する。すると１次成形樹脂と、１次成形樹脂とは異なる色の２次成形樹脂とからなる多色成形物が形成される。   For example, in a multi-color molded product molded using a plurality of resins, there are some in which different resins are connected to each other at the runner portion. Patent Document 1 describes a molding apparatus for molding such a multicolor molded product. In the molding apparatus described in Patent Document 1, a partition member is provided in the runner groove of the mold, and the partition member prevents the flow of the primary molding resin flowing from one side of the runner groove and the primary molding resin is cured. Thereafter, a secondary molding resin different from the primary molding resin is poured from the other of the runner grooves. At this time, the partition member is pushed out of the runner groove by the flow pressure of the secondary molding resin, so that the secondary molding resin flows into the position where the partition member is present and is welded to the primary molding resin. As a result, a multicolor molded product is formed which is composed of the primary molding resin and the secondary molding resin having a different color from the primary molding resin.

特開平８−２５８０８２号公報JP-A-8-258082

しかし特許文献１に記載の成形装置では、１次成形樹脂が硬化する前に２次成形樹脂が仕切り部材に到達してしまうと、仕切り部材があった位置で１次成形樹脂と２次成形樹脂が混じり合ってしまう場合がある。そのため、１次成形樹脂が硬化してから２次成形樹脂が仕切り部材に到達するように、２時成形樹脂の射出を遅らせる等して射出時を調整しなくてはならず、成形に時間が掛かっていた。   However, in the molding apparatus described in Patent Document 1, if the secondary molding resin reaches the partition member before the primary molding resin is cured, the primary molding resin and the secondary molding resin are located at the position where the partition member is located. May be mixed. Therefore, it is necessary to adjust the injection time by delaying the injection of the 2 o'clock molding resin so that the secondary molding resin reaches the partition member after the primary molding resin is cured. It was hanging.

A first joint part molded from the second resin part and a second joint part molded from the second resin, the first joint part having a concave shape having a wall part in contact with a part of the second joint part Formed. In addition, according to one aspect of the present invention, for example, a resin molded product that is molded from a plurality of resins and includes a joint portion where the first resin and the second resin merge with a runner, A first joint part molded from one resin and a second joint part molded from the second resin, wherein the first joint part has a wall part in contact with a part of the second joint part.

＜仕切り部材３０ａ＞
図１及び図２を参照して仕切り部材３０ａを詳述する。仕切り部材３０ａは、移動金型本体２（又は固定金型本体３）に、ランナー溝１６内を仕切るようにランナー溝１６内に出入可能に設けられている。この仕切り部材３０ａは、弾性部材３１ａによってランナー溝１６内に出る方向に付勢されている。 <Partition member 30a>
The partition member 30a will be described in detail with reference to FIGS. The partition member 30a is provided in the movable mold body 2 (or the fixed mold body 3) so as to be able to enter and exit the runner groove 16 so as to partition the runner groove 16. The partition member 30a is urged in a direction to exit into the runner groove 16 by the elastic member 31a.

図２に示すように、ランナー溝１６を仕切る仕切り部材３０ａは、断面形状は特に限定されないが、本実施例では丸軸状に形成されている。丸軸状であると、仕切り部材３０ａを収容する金型の加工が容易であったり、従来から用いられる突出しピンを加工して仕切り部材３０ａを製作することができる。なお仕切り部材３０ａは、丸軸状に限定されず、角柱状に形成されてもよい。   As shown in FIG. 2, the partition member 30 a that partitions the runner groove 16 is not particularly limited in cross-sectional shape, but is formed in a round shaft shape in the present embodiment. When the shape is round, the mold for housing the partition member 30a can be easily processed, or the protruding pin used conventionally can be processed to produce the partition member 30a. The partition member 30a is not limited to a round shaft shape, and may be formed in a prismatic shape.

仕切り部材３０ａの先部には、小径部３５が形成され、この小径部３５の先端が、コイルスプリング３１ａによって付勢され、ランナー溝１６内に突出し、雌型５１に押圧される。この小径部３５の一方の面（図２中奥側の面、規制面）３６は、後述するランナー溝１６内を流れる成形樹脂素材の流れる方向と略直角となっている。又、他方の面（図２中手前側の面）３７には、仕切り部材３０ａの上端面３９まで開放される段凹部４０が形成されている。   A small-diameter portion 35 is formed at the tip of the partition member 30a, and the tip of the small-diameter portion 35 is urged by the coil spring 31a, protrudes into the runner groove 16, and is pressed by the female die 51. One surface (surface on the back side in FIG. 2, regulating surface) 36 of the small diameter portion 35 is substantially perpendicular to the flow direction of the molding resin material flowing in the runner groove 16 described later. Further, a stepped recess 40 that is open to the upper end surface 39 of the partition member 30a is formed on the other surface (front surface in FIG. 2) 37.

段凹部４０の形状は、特に限定されるものではない。例えば、図２に示す段凹部４０は、断面円形状の上端面の中央に形成された半球状の窪みを形成する凹部４０ａと、この半球状の凹部から他方の面３７側に向かって切り欠かれた切欠き部４０ｂとを備える。   The shape of the stepped recess 40 is not particularly limited. For example, the stepped recess 40 shown in FIG. 2 includes a recess 40a that forms a hemispherical depression formed in the center of the upper end surface having a circular cross section, and a cutout from the hemispherical recess toward the other surface 37 side. And a notch 40b.

図３（Ａ）に、ランナー溝１６に仕切り部材３０ａが収容された状態の雄型５の斜視図を示す。またランナー溝１６には、仕切り部材３０ａを挟むように一対の絞りピン１６ａが配置される。絞りピン１６ａは、流れてきた樹脂の勢いを抑え、樹脂が仕切り部材３０ａを越えて反対側へ流れ込むことを防ぐ。ランナー溝１６には、仕切り部材３０ａに隣接して、仕切り部材３０ａの一方の面（規制面）３６側のランナー溝１６内に突出し、後述するランナーＲに仕切り部材３０ａの一部を覆う壁部１７ａ１を有する凹形状部１７ａを形成するための突起部１６ｂが配置される。図３（Ｂ）に、雄型５のランナー溝１６に収容された仕切り部材３０ａが、退避位置にある状態を示す。図３（Ｃ）は、仕切り部材３０ａの拡大斜視図を示す。なお、図３（Ａ），図３（Ｂ），図３（Ｃ）は、ランナー溝１６内に樹脂は充填されてない状態を示している。   FIG. 3A is a perspective view of the male mold 5 in a state where the partition member 30 a is accommodated in the runner groove 16. In the runner groove 16, a pair of throttle pins 16a are arranged so as to sandwich the partition member 30a. The squeezing pin 16a suppresses the momentum of the flowing resin and prevents the resin from flowing over the partition member 30a to the opposite side. The runner groove 16 is adjacent to the partition member 30a, protrudes into the runner groove 16 on the one surface (regulation surface) 36 side of the partition member 30a, and covers a part of the partition member 30a on the runner R described later. A protrusion 16b for forming a concave portion 17a having 17a1 is disposed. FIG. 3B shows a state in which the partition member 30a accommodated in the runner groove 16 of the male mold 5 is in the retracted position. FIG. 3C shows an enlarged perspective view of the partition member 30a. 3A, 3B, and 3C show a state where the runner groove 16 is not filled with resin.

＜ランナーＲ＞
図４及び図５を参照して、本実施形態におけるランナーＲについて説明する。図４（Ａ）、図５（Ａ）は、本発明の第一実施形態に係る樹脂成型品の一部を構成するランナーＲの斜視図である。図４（Ｂ）は、図４（Ａ）におけるＩＶ−ＩＶ断面図である。図５（Ｂ）は、図５（Ａ）におけるＶ−Ｖ断面図である。図４（Ａ）に示すように、ランナーＲは、第１樹脂Ａで形成される第１ランナー部Ａ１と、第２樹脂Ｂで形成される第２ランナー部Ｂ１と、第１樹脂Ａと第２樹脂Ｂとが合流するジョイント部１７とを備える。したがってランナーＲは、複数の樹脂から成形される樹脂成形品の一部を形成する。第１ランナー部Ａ１及び第２ランナー部Ｂ１は、ジョイント部１７を介して互いに反対側に配置され、それぞれ絞りピン１６ａによって形成された開口Ａ２及びＢ２を備える。 <Runner R>
With reference to FIG.4 and FIG.5, the runner R in this embodiment is demonstrated. 4 (A) and 5 (A) are perspective views of a runner R constituting a part of the resin molded product according to the first embodiment of the present invention. FIG. 4B is a cross-sectional view taken along the line IV-IV in FIG. FIG. 5B is a VV cross-sectional view in FIG. As shown in FIG. 4A, the runner R includes a first runner part A1 formed of the first resin A, a second runner part B1 formed of the second resin B, the first resin A and the first resin A. 2 joint B where 2 resin B merges is provided. Therefore, the runner R forms a part of a resin molded product molded from a plurality of resins. 1st runner part A1 and 2nd runner part B1 are arrange | positioned on the opposite side through the joint part 17, and are each provided with opening A2 and B2 formed with the throttle pin 16a.

ジョイント部１７は、第１樹脂Ａから成形される第１ジョイント部１７ａと、第２樹脂Ｂから成形される第２ジョイント部１７ｂとを備える。第２ジョイント部１７ｂは、後述する仕切り部材３０ａの退避によってランナー溝１６内に成形されるため、仕切り部材３０ａの段凹部４０の形状を転写した底部と、仕切り部材３０ａの小径部３５と同じ径の円筒部とを備える。   The joint portion 17 includes a first joint portion 17a molded from the first resin A and a second joint portion 17b molded from the second resin B. Since the second joint portion 17b is formed in the runner groove 16 by retracting a partition member 30a, which will be described later, the bottom portion to which the shape of the stepped recess 40 of the partition member 30a is transferred and the same diameter as the small diameter portion 35 of the partition member 30a. A cylindrical portion.

一方第１ジョイント部１７ａは、第２ジョイント部１７ｂの円筒部の側面の一部と接触する壁部１７ａ１と底部（深部）１７ａ２とを有する凹形状に形成される。つまり凹形状は、底部１７ａ２と、底部１７ａ２の周囲に立設された壁部１７ａ１とから構成される。しかしながら凹形状として上記のものに限定されることはなく、例えば底部１７ａ２と側壁１７ａ１とで画定される空間に代えて、上記段凹部４０の凹部４０ａのように、半球状の窪みを採用してもよい。つまり底部を備えていない凹形状としてもよい。こうすることで後述する突起部１６ｂの形状を簡単な形状とすることができる。   On the other hand, the 1st joint part 17a is formed in the concave shape which has wall part 17a1 and bottom (deep part) 17a2 which contact a part of side surface of the cylindrical part of the 2nd joint part 17b. That is, the concave shape is composed of a bottom portion 17a2 and a wall portion 17a1 provided upright around the bottom portion 17a2. However, the concave shape is not limited to the above. For example, instead of the space defined by the bottom portion 17a2 and the side wall 17a1, a hemispherical depression is adopted as in the concave portion 40a of the stepped concave portion 40. Also good. That is, it is good also as a concave shape which does not have a bottom part. By doing so, the shape of the protrusion 16b described later can be made simple.

なお本実施形態においては、底部１７ａ２は、矩形の一辺から第２ジョイント部１７ｂの断面形である円弧を切り取った形状としている。そして底部１７ａ２の円弧状部分に立設された壁部１７ａ１の一部が第２ジョイント部１７ｂの側面を覆うように配置される。また壁部１７ａ１の内周面は、第２ジョイント部１７ｂの一部に沿って形成される。こうすることで、第２ジョイント部１７ｂの側面を薄肉の壁部１７ａ１の一部で覆うことができ、少ない樹脂の容積で効果的に第１ジョイント部１７ａ１と第２ジョイント部１７ａ２との結合力を強固にすることができる（図４（Ｂ）参照）。   In the present embodiment, the bottom portion 17a2 has a shape obtained by cutting an arc that is a cross-sectional shape of the second joint portion 17b from one side of the rectangle. And it arrange | positions so that a part of wall part 17a1 standingly arranged by the circular-arc-shaped part of bottom part 17a2 may cover the side surface of the 2nd joint part 17b. The inner peripheral surface of the wall portion 17a1 is formed along a part of the second joint portion 17b. By doing so, the side surface of the second joint portion 17b can be covered with a part of the thin wall portion 17a1, and the coupling force between the first joint portion 17a1 and the second joint portion 17a2 can be effectively achieved with a small resin volume. Can be strengthened (see FIG. 4B).

一方例えば、第２ジョイント部１７ｂを断面矩形状の角柱とした場合、第１ジョイント部１７ａの壁部１７ａ１は、第２ジョイント部１７ｂの角柱の一側面と接触する一部直線状の壁部１７ａ１とすることもできる。つまり壁部１７ａ１としては、例えば湾曲形状のものに限定されず、直線状で構成されたものであってもよい。   On the other hand, for example, when the second joint portion 17b is a rectangular column having a rectangular cross section, the wall portion 17a1 of the first joint portion 17a is partly linear wall portion 17a1 that is in contact with one side surface of the square column of the second joint portion 17b. It can also be. That is, the wall portion 17a1 is not limited to a curved shape, for example, and may be a linear shape.

図５（Ｂ）に示す断面図を参照して、第１ジョイント部１７ａの詳細について説明する。断面円形の第２ランナー部Ｂ１（第１ランナー部Ａ１も同じ）の直径をＲ１とした場合、第１ジョイント部１７ａの厚さをｔ１とする。このとき厚さｔ１は、直径Ｒ１より小さく設定されている。例えばＲ１として約３．０ｍｍとした場合、厚さｔ１として約１．５ｍｍと設定してもよい。つまり第１ジョイント部１７ａは、第１ランナー部Ａ１または第２ランナー部Ｂ１よりも薄く形成されている。   Details of the first joint portion 17a will be described with reference to a cross-sectional view shown in FIG. When the diameter of the second runner part B1 having the circular cross section (the same applies to the first runner part A1) is R1, the thickness of the first joint part 17a is t1. At this time, the thickness t1 is set smaller than the diameter R1. For example, when R1 is about 3.0 mm, the thickness t1 may be set to about 1.5 mm. That is, the first joint portion 17a is formed thinner than the first runner portion A1 or the second runner portion B1.

さらに、図５（Ｂ）中少なくとも左右方向の壁部１７ａ１は、その内周面１７ａ１ａの少なくとも一部が、凹形状の底部１７ａ２から壁部１７ａ１の頂部に向かうにつれて凹形状の外側に傾斜角度Θ１で傾斜する傾斜面である。また壁部１７ａ１の外周面１７ａ１ｂの少なくとも一部は、壁部１７ａ１の頂部に向かうにつれて凹形状の内側に傾斜角度Θ２で傾斜する傾斜面である。なお傾斜角度Θ１、Θ２としては、約５度を例示することができる。   Furthermore, at least a part of the inner peripheral surface 17a1a of the wall portion 17a1 in the left-right direction in FIG. 5B is inclined outwardly toward the concave shape toward the top of the wall portion 17a1 from the concave bottom portion 17a2. It is an inclined surface inclined at. Further, at least a part of the outer peripheral surface 17a1b of the wall portion 17a1 is an inclined surface that is inclined inwardly at an inclination angle Θ2 toward the top of the wall portion 17a1. As the inclination angles Θ1 and Θ2, about 5 degrees can be exemplified.

壁部１７ａ１は、底部１７ａ２から壁部１７ａ１の頂部に向かうにつれて、水平方向の断面積が漸減するように構成される。つまり壁部１７ａ１の内・外周面を傾斜面とすることで、ランナーＲを金型から抜く際に、第１ジョイント部１７ａに作用する力を低減することができ、第１ジョイント部１７ａと第２ジョイント部１７ｂとの締結箇所に余計な力が作用することを防止できる。したがってランナーＲを金型から抜く際に、第１ジョイント部１７ａと第２ジョイント部１７ｂとの結合が解除され、分離してしまうことを防止できる。また、金型から抜く際に第１ジョイント部１７ａと第２ジョイント部１７ｂとの締結箇所に余計な力が作用することが抑止されていることで、成形完了時点で第１ジョイント部１７ａと第２ジョイント部１７ｂの結合がすでに弱くなっているというようなことを抑止することができる。そのため、本実施形態に係る樹脂成型品をプラスチックモデルキットにおけるプラスチックモデルのパーツとそれを支持するランナーに適用するような場合であっても、プラスチックモデルキットを商品包装箱に入れて運搬している途中で、振動や衝撃により第１ジョイント部１７ａと第２ジョイント部１７ｂとの結合が解除されてしまうというような事態が起きることを抑制することができる。   The wall 17a1 is configured such that the horizontal cross-sectional area gradually decreases from the bottom 17a2 toward the top of the wall 17a1. That is, when the inner and outer peripheral surfaces of the wall portion 17a1 are inclined surfaces, the force acting on the first joint portion 17a when the runner R is removed from the mold can be reduced. It is possible to prevent an excessive force from acting on the fastening portion with the two joint portions 17b. Therefore, when the runner R is removed from the mold, it is possible to prevent the first joint portion 17a and the second joint portion 17b from being disconnected and separated. In addition, since excessive force is prevented from acting on the fastening portion between the first joint portion 17a and the second joint portion 17b when being removed from the mold, the first joint portion 17a and the first joint portion 17a are formed when the molding is completed. It can be prevented that the coupling of the two joint portions 17b is already weak. Therefore, even when the resin molded product according to the present embodiment is applied to a plastic model part in a plastic model kit and a runner supporting the plastic model kit, the plastic model kit is carried in a product packaging box. It is possible to suppress the occurrence of a situation in which the connection between the first joint portion 17a and the second joint portion 17b is released due to vibration or impact.

また本実施形態においては、第１ジョイント部１７ａを構成する壁部１７ａ１及び底部１７ａ２は、それぞれ薄肉の部材で形成されているため、上記ランナーＲを金型から抜く際に、第１ジョイント部１７ａに作用する力をさらに低減することができると共に、後述する第１ジョイント部１７ａの硬化を早めている。例えば上記第１ジョイント部１７ａの厚さｔ１が約１．５ｍｍである場合、底部１７ａ２の厚さは約０．５ｍｍとすることができる。   Moreover, in this embodiment, since the wall part 17a1 and bottom part 17a2 which comprise the 1st joint part 17a are each formed with the thin member, when extracting the said runner R from a metal mold | die, the 1st joint part 17a Can be further reduced, and the hardening of the first joint portion 17a described later is accelerated. For example, when the thickness t1 of the first joint portion 17a is about 1.5 mm, the thickness of the bottom portion 17a2 can be about 0.5 mm.

さらに第１ジョイント部１７ａは、隣接する第１ランナー部Ａ１の第１ジョイント部１７ａと同じ長さにおける容積に対して、小さい容積で成形される。具体的には、図５（Ａ）を参照して、第１ジョイント部１７ａの軸方向長さをｄ１とし、第１ランナー部Ａ１における第１ジョイント部１７ａと同じ軸方向長さをｄ２とする。ｄ１とｄ２とは同じ長さである。このとき、第１ジョイント部１７ａの長さｄ１における容積は、第１ランナー部Ａ１の長さｄ２における容積より小さく設定されている。なお従来は、第１ジョイント部に相当する箇所は、例えば厚さ約２．５ｍｍでムク（中実）で成形されていた。   Furthermore, the 1st joint part 17a is shape | molded with a small volume with respect to the volume in the same length as the 1st joint part 17a of adjacent 1st runner part A1. Specifically, referring to FIG. 5A, the axial length of the first joint portion 17a is d1, and the same axial length as the first joint portion 17a in the first runner portion A1 is d2. . d1 and d2 are the same length. At this time, the volume at the length d1 of the first joint portion 17a is set smaller than the volume at the length d2 of the first runner portion A1. Conventionally, the portion corresponding to the first joint portion is formed with a thickness of about 2.5 mm, for example, with a solid (solid).

つまり上記したように、第１ジョイント部１７ａは、第１ランナー部Ａ１に比べ厚さが薄く設定され、さらに薄肉の壁部１７ａ１と底部１７ａ２とから構成される凹形状としているから、同じ長さの第１ランナー部Ａ１と比べて少ない容積となっている。こうすることで、第１ジョイント部１７ａと隣接する第１ランナー部Ａ１に対して、その容積を小さくすると共に金型との接触面積を広くすることで、後述する成形時に第１ジョイント部１７ａの硬化を早く行わせることができる。   That is, as described above, the first joint portion 17a is set to be thinner than the first runner portion A1, and has a concave shape composed of the thin wall portion 17a1 and the bottom portion 17a2, and therefore has the same length. The first runner part A1 has a smaller volume. In this way, the first runner portion A1 adjacent to the first joint portion 17a is reduced in volume and widened in contact area with the mold, so that the first joint portion 17a can be formed at the time of molding described later. Curing can be performed quickly.

＜成形工程＞
図６（Ａ）及び図６（Ｂ）を参照して、第一実施形態におけるランナーＲの成型工程を説明する。図６（Ａ）及び図６（Ｂ）に示す断面図は、例えば図３（Ａ）におけるＶＩ−ＶＩ線で金型を切断した断面図である。まず図１に示すように雄型５及び雌型５１が閉じられると、図示しない射出装置が、金型に接続され、例えば射出ノズルを連結する凹部１１から成形空間１８及びランナー溝１６にランナー溝の一方から流れる第１樹脂Ａを射出する（第１射出工程）。次いで第１樹脂Ａの射出完了を待たずに、射出装置が、例えば射出ノズルを連結する凹部１２から金型にランナー溝１６の他方から流れる第２樹脂Ｂを射出する（第２射出工程）。 <Molding process>
With reference to FIG. 6 (A) and FIG. 6 (B), the shaping | molding process of the runner R in 1st embodiment is demonstrated. The cross-sectional views shown in FIGS. 6A and 6B are cross-sectional views of the mold taken along line VI-VI in FIG. 3A, for example. First, as shown in FIG. 1, when the male mold 5 and the female mold 51 are closed, an injection device (not shown) is connected to the mold, and, for example, a runner groove is formed from the recess 11 connecting the injection nozzle to the molding space 18 and the runner groove 16. The first resin A flowing from one side is injected (first injection step). Next, without waiting for the completion of the injection of the first resin A, the injection device, for example, injects the second resin B flowing from the other of the runner grooves 16 into the mold from the recess 12 connecting the injection nozzle (second injection step).

第１射出工程において、第１樹脂Ａは、図６（Ａ）に示すように、図中左側から図中右側へと流れ、仕切り部材３０ａの一方の面（規制面）３６側であって、突起部１６ｂが配置されるランナー溝１６内の空間に第１樹脂Ａが充填される。このとき仕切り部材３０ａの規制面側が、ランナー溝１６の一方（図中左側）から流れる第１樹脂Ａの流れを規制する（規制工程）。つまり、仕切り部材３０ａは、一方の面３６が成形樹脂素材の流入方向と略直角となり、この一方の面３６側に流れる成形樹脂素材の流れを阻止することができる。そして第１樹脂Ａは、仕切り部材３０ａの一方の面３６に塞き止められ、流れが停止する。   In the first injection step, as shown in FIG. 6A, the first resin A flows from the left side in the drawing to the right side in the drawing, and is on one side (regulating surface) 36 side of the partition member 30a. The first resin A is filled in the space in the runner groove 16 where the protrusion 16b is disposed. At this time, the regulation surface side of the partition member 30a regulates the flow of the first resin A flowing from one side (left side in the drawing) of the runner groove 16 (regulation step). That is, in the partition member 30a, one surface 36 is substantially perpendicular to the inflow direction of the molded resin material, and the flow of the molded resin material flowing toward the one surface 36 can be prevented. The first resin A is blocked by one surface 36 of the partition member 30a, and the flow stops.

このとき第１樹脂Ａが、一方の面（規制面）３６側のランナー溝１６内に、仕切り部材３０ａの一部を囲む壁部１７ａ１及び底部１７ａ２を備える凹形状の第１ジョイント部（凹形状部）１７ａを成形する（第１成形工程）。ここで図３（Ａ）及び図３（Ｃ）を参照して、ランナー溝１６内の突起部１６ｂは、ランナー溝１６の面１６ｄと対向する第１側面１６ｂ１と仕切り部材３０ａの一方の面と所定距離離間して、仕切り部材３０ａの一部に沿った第２側面１６ｂ２とを備える。図３（Ｃ）に示すように第２側面１６ｂ２は、仕切り部材３０ａの一方の面と所定距離ｄだけ離間する。なお上記したように第１ジョイント部１７ａの壁部１７ａ１は傾斜面を備えているから、少なくとも突起部１６ｂの第１側面１６ｂ１及びランナー溝１６の面１６ｄは傾斜面に形成されている。   At this time, the first resin A has a concave first joint portion (concave shape) including a wall portion 17a1 and a bottom portion 17a2 surrounding a part of the partition member 30a in the runner groove 16 on the one surface (regulating surface) 36 side. Part) 17a is molded (first molding step). 3A and 3C, the protrusion 16b in the runner groove 16 includes a first side surface 16b1 facing the surface 16d of the runner groove 16 and one surface of the partition member 30a. A second side surface 16b2 is provided along a part of the partition member 30a at a predetermined distance. As shown in FIG. 3C, the second side surface 16b2 is separated from one surface of the partition member 30a by a predetermined distance d. As described above, since the wall portion 17a1 of the first joint portion 17a has an inclined surface, at least the first side surface 16b1 of the protrusion 16b and the surface 16d of the runner groove 16 are formed on the inclined surface.

上記したように、凹形状の第１ジョイント部１７ａは薄肉の壁部１７ａ１及び底部１７ａ２で形成されると共に、その容積が小さく設定されているため早く硬化する。つまり第１ジョイント部１７ａは、ランナー溝１６の突起部１６ｂにより、薄肉の底部１７ａ２とその周囲を囲む薄肉の壁部１７ａ１とを備えているから、金型との接触面積が広くなり早く硬化する。   As described above, the concave first joint portion 17a is formed by the thin wall portion 17a1 and the bottom portion 17a2, and is hardened quickly because its volume is set small. That is, the first joint portion 17a is provided with the thin bottom portion 17a2 and the thin wall portion 17a1 surrounding the periphery by the projection portion 16b of the runner groove 16, so that the contact area with the mold becomes wide and hardens quickly. .

例えば、突起部１６ｂが形成されていないランナー溝１６では、第１ジョイント部に該当する箇所に凹形状を有さない中実のランナーが形成されてしまう。こうなると、中実のランナー内部が冷却するまで所定時間を必要とするから、本実施形態のような凹形状の第１ジョイント部１７ａと比較して、硬化するまで所定の時間を費やすことになる。したがって、従来に比べ、第１樹脂Ａにより成形された凹形状の第１ジョイント部１７ａが迅速に硬化される（硬化工程）。   For example, in the runner groove | channel 16 in which the projection part 16b is not formed, the solid runner which does not have a concave shape will be formed in the location applicable to a 1st joint part. In this case, a predetermined time is required until the inside of the solid runner cools, and therefore, a predetermined time is spent until the solid runner is cured as compared with the concave first joint portion 17a as in the present embodiment. . Therefore, the concave first joint portion 17a formed by the first resin A is rapidly cured as compared with the conventional one (curing step).

次いで図６（Ｂ）に示すように、連結凹部５５に連結した射出ノズルにより例えば異なる色の第２樹脂Ｂがランナー溝１６に射出される。第２樹脂Ｂは、ランナー溝１６の他方から（図中右側から左側へ）流入されると、第２樹脂Ｂは仕切り部材３０ａの小径部３５の他方の面３７に一旦塞き止められるが、段凹部４０に流れ込む。この第２樹脂Ｂの流圧によって、段凹部４０の半球状凹部４１ａが矢印Ａ方向へ押圧され、仕切り部材３０ａは弾性部材３１ａの付勢力に抗して押し下げられる。このときの状態を図３（Ｂ）に示す。したがって、仕切り部材３０ａが、ランナー溝１６の他方から流れる第２樹脂Ｂの流れによってランナー溝１６から退避される（退避工程）。こうして、第２樹脂Ｂが、第１成形工程で形成された凹形状部と接合する接合部を成形する（第２形成工程）。   Next, as shown in FIG. 6B, for example, the second resin B having a different color is injected into the runner groove 16 by the injection nozzle connected to the connection recess 55. When the second resin B flows in from the other side of the runner groove 16 (from the right side to the left side in the figure), the second resin B is temporarily blocked by the other surface 37 of the small diameter portion 35 of the partition member 30a. It flows into the stepped recess 40. Due to the flow pressure of the second resin B, the hemispherical concave portion 41a of the stepped concave portion 40 is pressed in the direction of arrow A, and the partition member 30a is pushed down against the biasing force of the elastic member 31a. The state at this time is shown in FIG. Therefore, the partition member 30a is retracted from the runner groove 16 by the flow of the second resin B flowing from the other of the runner grooves 16 (retraction process). Thus, the second resin B molds the joint portion to be joined with the concave portion formed in the first molding step (second forming step).

つまり、第２樹脂Ｂが仕切り部材３０ａに到達する際には、第１ジョイント部１７ａの硬化は完了しているから、第１射出部が第１樹脂Ａを射出した後、第２射出部は第１樹脂Ａの射出完了を待たずに、第２樹脂Ｂを射出することができる。したがって、成形に係る時間が短縮された樹脂成型品を提供することができる。   That is, when the second resin B reaches the partition member 30a, the curing of the first joint portion 17a is completed. Therefore, after the first injection portion injects the first resin A, the second injection portion is The second resin B can be injected without waiting for completion of the injection of the first resin A. Therefore, it is possible to provide a resin molded product in which the time required for molding is shortened.

なお第２樹脂Ｂが仕切り部材３０ａに到達するタイミングは、金型のゲートから本発明の仕切り部材３０ａ及び突起部１６ｂまでの位置によって適宜変更されるが、少なくとも第１ジョイント部１７ａに相当する箇所の硬化が従来より早まることで、射出成型サイクルが短縮されると共に、金型設計（デザイン）の自由度も向上する。成型サイクルとしては、同じ金型のデザインで、本発明を適用したものと、従来のものとを比較すると、例えば３秒短縮される。   The timing at which the second resin B reaches the partition member 30a is appropriately changed depending on the positions from the gate of the mold to the partition member 30a and the protrusion 16b of the present invention, but at least a portion corresponding to the first joint portion 17a. Since the curing of the resin becomes faster than before, the injection molding cycle is shortened and the degree of freedom in designing the mold is improved. The molding cycle is shortened by, for example, 3 seconds when the present invention is applied to the conventional mold with the same mold design.

こうして成形されたランナーＲは、図４に示すように第１ジョイント部１７ａの壁部１７ａ１の一部によって形成された曲面部に仕切り部材３０ａの形状と対応した円筒状の第二ジョイント部１７ｂが嵌められる。つまり第１ジョイント部１７ａは、第二ジョイント部１７ｂの小径部を半分囲むような成形凹部を形成して、この成形凹部で第二ジョイント部１７ｂを包持する形となり、第１樹脂Ａによる第１ジョイント部１７ａと第２樹脂Ｂによる第２ジョイント部１７ｂとの溶着が強固なものになる。そのため、本実施形態に係る樹脂成型品をプラスチックモデルキットにおけるプラスチックモデルのパーツとそれを支持するランナーに適用した場合であっても、プラスチックモデルキットを商品包装箱に入れて運搬している途中で、振動や衝撃により第１ジョイント部１７ａと第２ジョイント部１７ｂとの溶着が解除されてしまうというような事態が起きることを抑制することができる。   As shown in FIG. 4, the runner R formed in this way has a cylindrical second joint portion 17b corresponding to the shape of the partition member 30a on the curved surface portion formed by a part of the wall portion 17a1 of the first joint portion 17a. Fitted. In other words, the first joint portion 17a is formed so as to form a molding recess that surrounds the small-diameter portion of the second joint portion 17b, and the second joint portion 17b is held by the molding recess. The weld between the first joint portion 17a and the second joint portion 17b by the second resin B becomes strong. Therefore, even when the resin molded product according to this embodiment is applied to a plastic model part in a plastic model kit and a runner that supports the plastic model kit, the plastic model kit is being transported in a product packaging box. It is possible to suppress the occurrence of a situation in which the welding between the first joint portion 17a and the second joint portion 17b is released due to vibration or impact.

その後、図１に示す移動金型本体２を固定金型本体３から離し、押圧軸２５を押圧して押し出し板２０を移動させると、押し出し板２０に設けられたノックアウトピン２１・・・が移動金型本体２の雄型５に付着した多色ランナーＲ及び多色成形物を押し出し、これらを取り出すことができる。上記実施例では、仕切り部材３０及び突起部１６ｂを移動金型本体２側に設けたが、固定金型本体３側に設けても構わない。また、仕切り部材３０を付勢する弾性部材としてコイルスプリング３１を使用したが、ゴム、板バネ等の他の弾性を有する部品を利用しても構わない。   Thereafter, when the movable mold body 2 shown in FIG. 1 is moved away from the fixed mold body 3 and the pressing shaft 25 is pressed to move the extrusion plate 20, the knockout pins 21... Provided on the extrusion plate 20 move. The multicolor runner R and the multicolor molded product attached to the male mold 5 of the mold body 2 can be extruded and taken out. In the above embodiment, the partition member 30 and the protruding portion 16b are provided on the movable mold body 2 side, but may be provided on the fixed mold body 3 side. Further, although the coil spring 31 is used as an elastic member for biasing the partition member 30, other elastic parts such as rubber and leaf springs may be used.

＜第二実施形態＞
図７及び図８には、仕切り部材１００が、ランナー溝８５内で突起部１２７を挟むように一対配置され、それぞれの仕切り部材１００の規制面１０６は、突起部１２７と対向して配置される形態を例示する。第一実施形態と異なる箇所は、仕切り部材１００が一対設けられている点であり、その他の構成について第一実施形態と第二実施形態とは同じである。 <Second embodiment>
7 and 8, a pair of partition members 100 are disposed so as to sandwich the protrusions 127 in the runner grooves 85, and the regulation surfaces 106 of the respective partition members 100 are disposed to face the protrusions 127. The form is illustrated. The difference from the first embodiment is that a pair of partition members 100 are provided, and the first embodiment and the second embodiment are the same for other configurations.

仕切り部材１００は、図２に示す仕切り部材３０ａと同様に丸軸状に形成され、先端に段凹部１１０が形成され、下端にフランジ１０２が設けられている。この仕切り部材１００は、後部が前部押し出し板９０に形成された軸孔９９に摺動自在に設けられている。仕切り部材１００のフランジ１０２は、前部押し出し板９０の摺動穴９６に摺動自在に取り付けられ、後部押し出し板９１のスプリング受け穴１０４に設けられたスプリング１０１によって、ランナー溝８５方向に付勢され、摺動穴９６の上壁１０３に係合するようになっている。   The partition member 100 is formed in a round shaft shape like the partition member 30a shown in FIG. 2, has a stepped recess 110 formed at the tip, and a flange 102 provided at the lower end. The partition member 100 has a rear portion slidably provided in a shaft hole 99 formed in the front pushing plate 90. The flange 102 of the partition member 100 is slidably attached to the sliding hole 96 of the front pushing plate 90 and is urged toward the runner groove 85 by the spring 101 provided in the spring receiving hole 104 of the rear pushing plate 91. Thus, the upper wall 103 of the sliding hole 96 is engaged.

またフランジ１０２は、スプリング１０１の弾性に抗して、スプリング受け穴１０４の上部に形成された段部１１７に当接するまで押し下げられるようになっている。さらに摺動穴９６の一側には、係合溝１１６が形成され、この係合溝１１６にフランジ１０２に設けられた係合軸１１５が摺動自在に係合するようになっている。そのため、仕切り部材１００は、回転することがない。   Further, the flange 102 is pushed down until it abuts against a stepped portion 117 formed in the upper portion of the spring receiving hole 104 against the elasticity of the spring 101. Further, an engagement groove 116 is formed on one side of the slide hole 96, and an engagement shaft 115 provided on the flange 102 is slidably engaged with the engagement groove 116. Therefore, the partition member 100 does not rotate.

仕切り部材１００の先端は、コイルスプリング１０１の弾性によって付勢され、ランナー溝８５内に突出し、雌型１２２に押圧する。この仕切り部材１００の一方の面１０６は、ランナー溝８５内を流れる成形樹脂素材の流れる方向と略直角となっている。又他方の面１０７には、仕切り部材１００の上端面１０９まで開放される段凹部１１０が形成されている。この仕切り部材１００は、二つ一組となって、各ランナー溝８５内に突出するようになっている。この二つの仕切り部材１００，１００は、互いに一方の面１０６，１０６が対向するように設けられている。   The tip of the partition member 100 is biased by the elasticity of the coil spring 101, protrudes into the runner groove 85, and presses against the female mold 122. One surface 106 of the partition member 100 is substantially perpendicular to the flow direction of the molding resin material flowing in the runner groove 85. A stepped recess 110 is formed on the other surface 107 so as to open up to the upper end surface 109 of the partition member 100. The partition members 100 are in pairs and project into the runner grooves 85. The two partition members 100 and 100 are provided such that one surfaces 106 and 106 face each other.

射出装置によって、図８（Ａ）に示すように、ランナー溝８５の一方（図中左側）から第１樹脂Ａを流入する。この第１樹脂Ａは、図中左側の仕切り部材１００の他方の面１０７に形成された段凹部１１０に流れ込む。この第１樹脂Ａの流圧によって段凹部１１０の底面１１１が押圧され、図中左側の仕切り部材１００は弾性部材１０１の付勢力に抗して押し下げられる。第１樹脂Ａはそのままランナー溝８５内を流れ、次の仕切り部材１００の一方の面１０６に塞き止められ、流れが停止する。このとき、凹形状の第１ジョイント部２１７ａが形成される。   As shown in FIG. 8 (A), the first resin A flows in from one side (left side in the figure) of the runner groove 85 by the injection device. The first resin A flows into the stepped recess 110 formed on the other surface 107 of the left partition member 100 in the drawing. The bottom surface 111 of the stepped recess 110 is pressed by the flow pressure of the first resin A, and the partition member 100 on the left side in the drawing is pressed down against the urging force of the elastic member 101. The first resin A flows in the runner groove 85 as it is, is blocked by one surface 106 of the next partition member 100, and the flow stops. At this time, a concave first joint portion 217a is formed.

射出装置によって、図８（Ｂ）に示すように、ランナー溝８５の他方（図中右側）から別の色の第２樹脂Ｂを流入すると、この第２樹脂Ｂは図中右側の仕切り部材１００の他方の面１０７に形成された段凹部１１０に流れ込む。この第２樹脂Ｂの流圧によって、段凹部１１０の底面１１１が押圧され、図中右側の仕切り部材１００は弾性部材１０１の付勢力に抗して押し下げられる。別の色の第２樹脂Ｂは、図中右側の仕切り部材１００があった位置に流れ込み、最初の第１樹脂Ａと溶着する。このようにして、ランナー溝８５内において多色のランナー８４が成形される。   As shown in FIG. 8 (B), when the second resin B of another color flows from the other (right side in the drawing) of the runner groove 85 by the injection device, the second resin B is separated from the partition member 100 on the right side in the drawing. It flows into the stepped recess 110 formed on the other surface 107. The bottom surface 111 of the stepped recess 110 is pressed by the flow pressure of the second resin B, and the right partition member 100 in the drawing is pressed down against the urging force of the elastic member 101. The second resin B of another color flows into the position where the partition member 100 on the right side in the drawing was present, and is welded to the first first resin A. In this way, a multicolor runner 84 is formed in the runner groove 85.

以上のように形成されたランナー８４を図１０及び図１１に示す。図１０及び図１１に示すランナー８４は、その参照符号の最初に２を付すことで図５及び図６に示すランナーＲと同じ部材を示している。なおランナー８４は、ランナーＲと第１ジョイント部２１７ａに仕切り部材１００に対応する形状の部分２００が形成されている点が異なる以外は同様の形状である。   The runner 84 formed as described above is shown in FIGS. The runner 84 shown in FIG.10 and FIG.11 has shown the same member as the runner R shown in FIG.5 and FIG.6 by attaching | subjecting 2 to the beginning of the reference symbol. The runner 84 has the same shape except that the runner R and the first joint portion 217a are formed with a portion 200 having a shape corresponding to the partition member 100.

以上の第二実施形態では、例えばランナー溝８５の突起部１２７の両側に仕切り部材１００を配置しているため、各射出ノズルの射出時を調節することなく、例えば同時に射出させることができる。このように、一つのランナー溝内に相対する仕切り部材３０を一対設けることにより、第１樹脂Ａまたは第２樹脂Ｂのどちらか一方が先に突起部１２７に到達すればその樹脂の硬化が早まるため、各射出ノズルの射出時を調節することがなく、同時に射出させることができ、成形効率をさらに向上させることができる。   In the second embodiment described above, for example, since the partition members 100 are arranged on both sides of the protrusion 127 of the runner groove 85, it is possible to inject simultaneously, for example, without adjusting the injection time of each injection nozzle. Thus, by providing a pair of opposing partition members 30 in one runner groove, if either one of the first resin A or the second resin B reaches the projection 127 first, curing of the resin is accelerated. Therefore, it is possible to inject simultaneously without adjusting the injection time of each injection nozzle, and the molding efficiency can be further improved.

以上説明してきたように、本実施形態においては、従来の成形装置のようにジョイント部分の硬化を待つ必要がなく、一つの成形型で、突起部を設けるだけの極めて簡単な機構で多色ランナー又は多色成形物を成形する際の射出時間を短縮することができる。また、機構が単純で、小型化且つ軽量化することができるので、安価に製造することができ、射出装置に取り付けても射出装置の負担が少ないという効果がある。さら各色の成形樹脂素材を順に射出して成形する必要がなく、同時に射出成形することも可能であるため、成形物の成形サイクルが極めて短くなり、生産効率を高め、生産コストを下げることができる。   As described above, in this embodiment, there is no need to wait for the joint portion to be hardened as in the conventional molding apparatus, and the multicolor runner has a very simple mechanism in which only one projection die is provided. Or the injection time at the time of shape | molding a multicolor molded object can be shortened. In addition, since the mechanism is simple and can be reduced in size and weight, it can be manufactured at a low cost, and there is an effect that the burden on the injection device is small even if it is attached to the injection device. Furthermore, it is not necessary to inject and mold the molding resin materials of each color in order, and injection molding is possible at the same time, so the molding cycle of molded products can be extremely shortened, increasing production efficiency and reducing production costs. .

また仕切り部材の一方の面の近傍におけるジョイント部の第１樹脂Ａの量が少なくなるため、従来の成形装置に比べて、仕切り部材の一方の面の近傍における第１樹脂Ａは早く硬化する。このことにより、第２樹脂Ｂを従来の成形装置の場合よりも早く射出できるので、成形効率を向上させることができと共に、金型設計の自由度を向上させることができる。本発明は、例えばプラスチックモデルキット等、成形品とランナーとが分離されていない状態で流通される樹脂成型品に適用可能である。   Further, since the amount of the first resin A in the joint portion in the vicinity of the one surface of the partition member is reduced, the first resin A in the vicinity of the one surface of the partition member is cured faster than in the conventional molding apparatus. Accordingly, the second resin B can be injected faster than in the case of a conventional molding apparatus, so that the molding efficiency can be improved and the degree of freedom in mold design can be improved. The present invention is applicable to a resin molded product such as a plastic model kit that is distributed in a state where the molded product and the runner are not separated.
