ここで、第２の金型８２における成形部８２０のロッド成形部８２０ａの軸方向の長さをＬとし、スライドピン８３の軸方向の長さをｌとすると、長さＬは、少なくとも長さｌよりも大きく（Ｌ＞ｌ）、かつ、長さＬと長さｌとの差（Ｌ－ｌ）は、例えば３ｍｍ以内である。 Here, assuming that the axial length of the rod forming portion 820a of the forming portion 820 of the second mold 82 is L and the axial length of the slide pin 83 is l, the length L is at least the length The difference (L-1) between the length L and the length l is, for example, within 3 mm, which is larger than l (L> l).
第２工程は、図７Ｃに示すように、スライドピン８３が保持部８２１に保持された状態で、第１及び第２の金型８１，８２の成形用空間８１０，８２０に溶融樹脂Ａを射出して充填する工程である。第２工程において、溶融樹脂Ａは成形用空間８１０，８２０の本体成形部８１０ｂ，８２０ｂ側から射出されて、ロッド成形部８１０ａ，８２０ａ側から本体成形部８２０ａ，８２０ｂに向けて充填されていく。この際、スライドピン８３には高圧な樹脂圧が作用する。 In the second step, as shown in FIG. 7C, the molten resin A is injected into the molding spaces 810 and 820 of the first and second molds 81 and 82 while the slide pin 83 is held by the holding portion 821. And filling. In the second step, the molten resin A is injected from the main body molding portions 810b and 820b of the molding spaces 810 and 820, and is filled from the rod molding portions 810a and 820a toward the main body molding portions 820a and 820b. At this time, a high resin pressure acts on the slide pin 83.
第３工程は、溶融樹脂Ａを冷却して固化した後にスライドピン８３を保持部８２１の挿入孔８２１ａから引き抜く工程である。図７Ｄに示すように、溶融樹脂Ａが固化されると、成形用空間８１０，８２０の形状に対応した成形品８００が形成される。成形品８００は、第１の形成部８００ａと第２の形成部８００ｂとを有し、第１の形成部８００ａが移動部材５のロッド部５２に対応し、第２の形成部８００ｂが移動部材５の本体部５１に対応する。 The third step is a step of pulling out the slide pin 83 from the insertion hole 821a of the holding portion 821 after the molten resin A is cooled and solidified. As shown in FIG. 7D, when the molten resin A is solidified, a molded article 800 corresponding to the shape of the molding spaces 810 and 820 is formed. The molded product 800 has a first forming portion 800a and a second forming portion 800b, the first forming portion 800a corresponds to the rod portion 52 of the moving member 5, and the second forming portion 800b is a moving member. This corresponds to the main body 51 of the fifth embodiment.
第３工程では、スライドピン８３を軸方向に沿って移動させ、スライドピン８３を保持部８２１の挿入孔８２１ａから引き抜いて、第２の金型８２からスライドピン８３を離脱させる。これにより、成形品８００の中心部に中空が形成される。すなわち、スライドピン８３が引き抜かれることにより形成された空間が、成形品８００の中空部８０１ａとして形成される。この成形品８００の中空部８０１ａは、ロッド部５２の中心部に形成された中空状の肉抜き部５２０に対応する。 In the third step, the slide pin 83 is moved along the axial direction, the slide pin 83 is pulled out from the insertion hole 821 a of the holding portion 821, and the slide pin 83 is released from the second mold 82. Thus, a hollow is formed at the center of the molded article 800. That is, a space formed by pulling out the slide pin 83 is formed as the hollow portion 801 a of the molded article 800. The hollow portion 801 a of the molded article 800 corresponds to the hollow thin portion 520 formed at the center of the rod portion 52.
以上説明したように、保持部８２１が設けられた第２の金型８２と、スライドピン８３を用いることで、中心部が中空状であるロッド部５２を備えた移動部材５を製造することができる。ここで、例えば保持部８２１がない金型を用いた場合には、溶融樹脂Ａを射出する際の樹脂圧によってスライドピン８３が曲がってしまうという問題がある。さらに、スライドピン８３が曲がった状態で溶融樹脂Ａが冷却、固化されるので、スライドピン８３を引き抜く際にスライドピン８３が折れて破損する可能性がある。 As described above, by using the second mold 82 provided with the holding portion 821 and the slide pin 83, the moving member 5 provided with the rod portion 52 whose central portion is hollow can be manufactured. it can. Here, for example, when a mold without the holding portion 821 is used, there is a problem that the slide pin 83 is bent by the resin pressure when the molten resin A is injected. Furthermore, since the molten resin A is cooled and solidified in a state where the slide pin 83 is bent, the slide pin 83 may be broken and broken when the slide pin 83 is pulled out.
本実施の形態では、スライドピン８３を保持する保持部８２１を第２の金型８２に設けることにより、上述したスライドピン８３の破損を防止することで、ロッド部５２の中心部に中空状の肉抜き部を形成することを可能にしている。 In the present embodiment, the second mold 82 is provided with a holding portion 821 for holding the slide pin 83, thereby preventing breakage of the slide pin 83 described above, whereby a hollow portion is formed at the central portion of the rod portion 52. It is possible to form a lightening.
（実施の形態の作用及び効果）
以上説明した本実施の形態によれば、以下に示す作用及び効果が得られる。 (Operation and effect of the embodiment)
According to the embodiment described above, the following operation and effect can be obtained.
（１）ロッド部５２の製造工程は、第１及び第２の金型８１，８２に充填された溶融樹脂Ａを冷却して固化した後にスライドピン８３を引き抜く第３工程を有し、スライドピン８３が引き抜かれたことにより形成された空間が成形品８００の中空部８０１ａとして形成される。これにより、移動部材５のロッド部５２の中心部に中空状の肉抜き部５２０を設けることができるので、ロッド部５２の肉厚が減ぜられてボイドの発生が抑制されたロッド部５２を製造することが可能である。また、特許文献２，３に記載された金型のように複雑な構成を必要としないので、簡素な方法でボイド率の低減を図ることができるができる。 (1) The manufacturing process of the rod portion 52 has a third step of extracting the slide pin 83 after cooling and solidifying the molten resin A filled in the first and second molds 81 and 82, the slide pin A space formed by drawing 83 is formed as the hollow portion 801 a of the molded article 800. As a result, since the hollow thinned portion 520 can be provided at the center of the rod portion 52 of the moving member 5, the thickness of the rod portion 52 is reduced and the rod portion 52 in which the generation of the void is suppressed is obtained. It is possible to manufacture. In addition, since a complicated configuration as in the molds described in Patent Documents 2 and 3 is not required, the void ratio can be reduced by a simple method.
（２）保持部８２１にはスライドピン８３を挿入する挿入孔８２１ａが形成されているので、溶融樹脂Ａの樹脂圧によってスライドピン８３が破損することが防止される。 (2) Since the insertion hole 821a into which the slide pin 83 is inserted is formed in the holding portion 821, breakage of the slide pin 83 due to the resin pressure of the molten resin A is prevented.
（３）保持部８２１が第１及び第２の金型８１，８２のうち第２の金型８２にのみ設けられているので、第１及び第２の金型８１，８２の両方に保持部を設ける場合に比較して、金型の構成を簡素化することができ、製造コストの低減を図ることができる。 (3) Since the holding portion 821 is provided only for the second mold 82 among the first and second molds 81 and 82, the holding portions for both the first and second molds 81 and 82 As compared with the case where is provided, the configuration of the mold can be simplified, and the manufacturing cost can be reduced.
次に、変形例１について、図８を参照して説明する。図８は、変形例１に係る第１及び第２の金型８１Ａ，８２Ａの構成を示す斜視図である。変形例１は、本実施の形態に係る第１及び第２の金型８１，８２と構成が異なる他は、同様の構成である。なお、図８及び図９において、上記実施の形態について説明したものと共通する機能を有する構成要素については、同一の又は対応する符号及び名称を付してその説明を省略する。 Next, Modified Example 1 will be described with reference to FIG. FIG. 8 is a perspective view showing the configuration of first and second molds 81A and 82A according to the first modification. Modification 1 is the same configuration as the first and second molds 81 and 82 according to the present embodiment, except for the configuration. In FIG. 8 and FIG. 9, the same or corresponding symbols and names are assigned to components having the same functions as those described in the above embodiment, and the description thereof is omitted.
図８に示すように、変形例１に係る第２の金型８２Ａには、スライドピン８３を保持する保持部８２１Ａが設けられている。保持部８２１Ａには、第１の金型８１Ａ側に開口した凹部８２１ｂが形成されている。 As shown in FIG. 8, the second mold 82A according to the first modification is provided with a holding portion 821A for holding the slide pin 83. In the holding portion 821A, a concave portion 821b opened to the side of the first mold 81A is formed.
凹部８２１ｂには、スライドピン８３を保持する保持面８２１ｃがスライドピン８３の外周面に沿った曲率で形成された円弧面である。つまり、保持部８２１Ａの凹部８２１ｂは、スライドピン８３の軸方向に沿って見た場合に円弧状である。 In the recess 821 b, a holding surface 821 c for holding the slide pin 83 is an arc surface formed with a curvature along the outer peripheral surface of the slide pin 83. That is, when viewed in the axial direction of the slide pin 83, the concave portion 821b of the holding portion 821A has an arc shape.
変形例１によれば、溶融樹脂Ａが射出された際にスライドピン８３に対する樹脂圧が第２の金型８２Ａ側に作用した場合に、スライドピン８３が曲がることを防止することができる。なお、樹脂圧によるスライドピン８３が曲がる方向をシミュレーション解析等で予め把握しておけば、本変形例の形態がより有効となる。 According to the first modification, when the resin pressure on the slide pin 83 acts on the second mold 82A side when the molten resin A is injected, it is possible to prevent the slide pin 83 from bending. If the direction in which the slide pin 83 bends due to the resin pressure is grasped in advance by simulation analysis or the like, the form of the present modification becomes more effective.
次に、変形例２について図９～図１０Ｂを参照して説明する。 Next, Modification 2 will be described with reference to FIGS. 9 to 10B.
図９は、変形例２に係る第１及び第２の金型８１Ｂ，８２Ｂの構成例を示す斜視図である。図１０Ａは、変形例２に係る第１及び第２の金型８１Ｂ，８２Ｂを重ねた状態をスライドピン８３の軸方向に沿った見た場合の断面図であり、図１０Ｂは図１０ＡにおけるＤ－Ｄ線に沿った断面図である。なお、図１０ＡのＤ―Ｄ線は、スライドピン８３の中心点を通る平面で切った断面線である。 FIG. 9 is a perspective view showing a configuration example of first and second molds 81B and 82B according to the second modification. FIG. 10A is a cross-sectional view of a state in which the first and second molds 81B and 82B according to the second modification are stacked, as viewed along the axial direction of the slide pin 83. FIG. FIG. 7 is a cross-sectional view taken along the line −D. Note that line DD in FIG. 10A is a cross-sectional line cut by a plane passing through the center point of the slide pin 83.
変形例２に係る第１及び第２の金型８１Ｂ，８２Ｂには、それぞれにスライドピン８３を保持する保持部が設けられている点で本実施の形態に係る第１及び第２の金型８１，８２と構成が異なる。従って、変形例２に係る第１及び第２の金型８１Ｂ，８２Ｂは、保持部を除いたその他の構成は、実施の形態に係る第１及び第２の金型８１，８２と同様の構成である。なお、図９～図１０Ｂにおいて、上記実施の形態について説明したものと共通する機能を有する構成要素については、同一の又は対応する符号及び名称を付してその説明を省略する。 The first and second molds according to the present embodiment are different in that the first and second molds 81B and 82B according to the modification 2 are provided with holding portions for holding the slide pins 83 respectively. The configuration is different from 81, 82. Therefore, the first and second molds 81B and 82B according to the second modification have the same configuration as the first and second molds 81 and 82 according to the embodiment except for the holding portion. It is. 9 to 10B, components having the same functions as those described in the above embodiment are given the same or corresponding reference numerals and names, and the description thereof is omitted.
図９～図１０Ｂに示すように、変形例２に係る第１の金型８１Ｂには第１の保持部８４１が設けられ、第２の金型８２Ｂには第２の保持部８４２が設けられている。第１の保持部８４１は、第１の金型８１Ｂの本体成形部８１０ｂの第１壁面８１０ｃから突出し、第２の保持部８４２は第２の金型８２Ｂの本体成形部８２０ｂの第２壁面８２０ｃから突出している。 As shown in FIG. 9 to FIG. 10B, the first holding part 841 is provided in the first mold 81B according to the second modification, and the second holding part 842 is provided in the second mold 82B. ing. The first holding portion 841 protrudes from the first wall surface 810c of the main body molding portion 810b of the first mold 81B, and the second holding portion 842 is a second wall surface 820c of the main body molding portion 820b of the second mold 82B. Protruding from
図１０Ａに示すように、スライドピン８３の径方向であって、第１及び第２壁面８１０ｃ，８２０ｃと平行な平面に沿った方向の第１及び第２保持部８４１，８４２の長さｗは、スライドピン８３の外径ｄよりも小さい（ｗ＜ｄ）。ここで、例えば第１及び第２保持部８４１，８４２の長さｗがスライドピン８３の外径ｄよりも大きい場合は（ｗ＞ｄ）、保持部のサイズが大きくなる結果、第２肉抜き部５２０ｂの体積も増大してロッド部５２の強度が低下してしまう。これに対して本変形例２に係る第１及び第２の金型８１Ｂ，８２Ｂでは、保持部の体積を小さくできるので、ロッド部５２の強度を向上させることが可能である。 As shown in FIG. 10A, the length w of the first and second holding portions 841 and 842 in the radial direction of the slide pin 83 and along the plane parallel to the first and second wall surfaces 810c and 820c is , Smaller than the outer diameter d of the slide pin 83 (w <d). Here, for example, when the length w of the first and second holding portions 841 and 842 is larger than the outer diameter d of the slide pin 83 (w> d), the size of the holding portion is increased, and as a result, the second thinning is performed. The volume of the portion 520b also increases and the strength of the rod portion 52 decreases. On the other hand, in the first and second molds 81B and 82B according to the second modification, since the volume of the holding portion can be reduced, the strength of the rod portion 52 can be improved.
第１の金型８１Ｂの第１壁面８１０ｃと第２の金型８２Ｂの第２壁面８２０ｃとは対向する。ロッド部５２を製造する際には、第１工程において、第１壁面８１０ｃと第２壁面８２０ｃとの間の隙間をスライドピン８３が移動する。そして、スライドピン８３を第１保持部８４１と第２保持部８４２との間を挿通させて、第１及び第２保持部８４１，８４２に保持させる。 The first wall surface 810c of the first mold 81B and the second wall surface 820c of the second mold 82B face each other. When manufacturing the rod portion 52, the slide pin 83 moves in the gap between the first wall surface 810c and the second wall surface 820c in the first step. Then, the slide pin 83 is inserted between the first holding portion 841 and the second holding portion 842 and held by the first and second holding portions 841 and 842.
第１保持部８４１は第２保持部８４２と対向して所定の曲率で湾曲した円弧状の対向面８４１ａを有している。同様に、第２保持部８４２は第１保持部と対向して所定の曲率で湾曲した円弧状の対向面８４２ａを有している。第１保持部８４１の対向面８４１ａと第２保持部８４２の対向面８４２ａとの間の隙間が最も大きくなる寸法（対向面８４１ａ及び対向面８４２ａの最も凹んだ部位における隙間の距離）をＣとすると、寸法Ｃはスライドピン８３の外径ｄよりわずかに大きい寸法である（Ｃ＞ｄ）。 The first holding portion 841 is opposed to the second holding portion 842 and has an arc-shaped opposite surface 841 a curved with a predetermined curvature. Similarly, the second holding portion 842 has an arc-shaped facing surface 842a which is curved at a predetermined curvature to face the first holding portion. A dimension where the gap between the opposing surface 841a of the first holding portion 841 and the opposing surface 842a of the second holding portion 842 is the largest (the distance of the gap at the most concave portion of the opposing surface 841a and the opposing surface 842a) is C Then, the dimension C is a dimension slightly larger than the outer diameter d of the slide pin 83 (C> d).
変形例２によれば、スライドピン８３を第１保持部８４１及び第２保持部８４２で挟み込んで保持することができるので、溶融樹脂Ａを射出した際の樹脂圧によるスライドピン８３の曲げを防止することができる。 According to the second modification, the slide pin 83 can be held between the first holding portion 841 and the second holding portion 842 so that bending of the slide pin 83 due to resin pressure when the molten resin A is injected can be prevented. can do.
次に、変形例３について図１１を参照して説明する。図１１は、変形例３に係る第２の金型８２Ｃの構成例を示す斜視図である。 Next, a third modification will be described with reference to FIG. FIG. 11 is a perspective view showing a configuration example of a second mold 82C according to the third modification.
変形例３に係る第２の金型８２Ｃは、保持部が形成されていない点で本実施の形態及び上記変形例１，２と異なる。つまり、本変形例に係る第２の金型８２Ｃには、スライドピン８３を保持する保持器８５が備え付けられている。すなわち、本実施の形態では、スライドピン８３を保持する保持部８２１が第２の金型８２に一体に形成されていたが、本変形例では保持部が金型とは別体に設けられている。 The second mold 82C according to the third modification differs from the present embodiment and the first and second modifications in that the holding portion is not formed. That is, the holder 85 for holding the slide pin 83 is provided to the second mold 82C according to the present modification. That is, in the present embodiment, the holding portion 821 for holding the slide pin 83 is formed integrally with the second mold 82, but in the present modification, the holding portion is provided separately from the mold. There is.
保持器８５は、長尺に形成された略直方形状であり、その先端部にスライドピン８３を挿通するための挿通孔８５ａが形成されている。保持器８５は、その延伸方向が第２の金型８２Ｃのロッド成形部８２０ａ及び本体成形部８２０ｂの長手方向と直交するように配置され、第２の金型８２Ｃに形成された配置孔８２０ｅに嵌合している。 The holder 85 has a substantially rectangular shape formed in a long shape, and an insertion hole 85a for inserting the slide pin 83 is formed at the tip thereof. The holder 85 is disposed so that the extending direction is orthogonal to the longitudinal direction of the rod molding portion 820a and the body molding portion 820b of the second mold 82C, and the retainer hole 85e is formed in the second mold 82C. It is fitting.
本変形例によれば、保持器８５がスライドピン８３を挿通する挿通孔８５ａを有しているので、溶融樹脂Ａの樹脂圧によってスライドピン８３が破損することが防止される。また、本変形例では、スライドピン８３を保持する保持部が第２の金型８２Ｃと別体に設けられているので、例えばスライドピン８３の外径を変更したい場合には金型の形状を変更する必要がないので、汎用性が高い。さらに、第２の金型８２Ｃにスライドピン８３を保持する保持部を設ける必要がないので、金型の製造コスト及び運用コストを低減することができる。 According to this modification, since the holder 85 has the insertion hole 85a for inserting the slide pin 83, breakage of the slide pin 83 due to the resin pressure of the molten resin A is prevented. Further, in the present modification, since the holding portion for holding the slide pin 83 is provided separately from the second mold 82C, for example, when it is desired to change the outer diameter of the slide pin 83, the shape of the mold is set. Versatility is high because there is no need to change. Furthermore, since it is not necessary to provide the second mold 82C with a holding portion for holding the slide pin 83, the manufacturing cost and operation cost of the mold can be reduced.
