本発明は、転写面を有する転写部材と基材とを備える成形型に関する。 The present invention relates to a mold having a transfer member having a transfer surface and a substrate.
従来、レンズ、プリズム、ミラー等の光学素子或いはその他の被成形物を成形する際には、例えば上下一対の成形型を用いて、上記の成形型間に光学素子材料等を投入して被成形物を成形している。 Conventionally, when molding optical elements such as lenses, prisms, mirrors, or other objects to be molded, for example, using a pair of upper and lower molds, an optical element material or the like is placed between the molds to be molded. The object is being molded.
成形型としては、被成形物に面形状を転写する転写面を有しガラス等からなる転写部材と、金属材料等からなる基材とが接合されたものが知られている。この成形型を製造（成形）する際には、転写部材を成形温度まで加熱した後、基材に対して加圧することによって転写部材と基材とを接合する手法が採られている（例えば、特許文献１参照）。
ところで、上記特許文献１記載の成形型は、通常、転写部材の線膨張係数と基材の線膨張係数とが異なるため、光学素子の成形時、成形型自体の製造時等の加熱により、主に転写部材に熱応力が発生し、これに起因して転写部材の基材との接合面からクラックが入りやすかった。 By the way, since the linear expansion coefficient of the transfer member and the linear expansion coefficient of the base material are usually different from each other, the molding die described in Patent Document 1 is mainly heated by heating during molding of the optical element, manufacturing of the molding die itself, and the like. As a result, thermal stress was generated in the transfer member, and it was easy for cracks to enter from the joint surface of the transfer member with the base material.
このように転写部材等にクラックが入ると、このクラックが徐々に拡大し、最終的には転写部材等が割れてしまう。更には、転写部材等の割れにより、転写部材と基材との接合が剥がれてしまう。 When cracks are formed in the transfer member or the like in this way, the cracks are gradually expanded, and eventually the transfer member or the like is cracked. Furthermore, the joining between the transfer member and the base material is peeled off due to cracking of the transfer member or the like.
本発明の課題は、上記従来の実情に鑑み、加熱時における成形型の割れを抑える成形型を提供することである。 The subject of this invention is providing the shaping | molding die which suppresses the crack of the shaping | molding die at the time of a heating in view of the said conventional situation.
上記課題を解決するために、本発明の成形型は、被成形物に面形状を転写する転写面を有する転写部材と、少なくともこの転写部材を支持する基材とを備える成形型において、上記転写部材と上記基材とは、直接又はそれらの中間に位置する中間層部材を介して接合され、上記転写部材の接合面、上記基材の接合面、上記中間層部材の上記転写部材との接合面、及び、上記中間層部材の上記基材との接合面、の中の少なくとも１面は、直接接合しない部分である非接合部を有する構成とする。 In order to solve the above-mentioned problems, the molding die of the present invention is a molding die comprising a transfer member having a transfer surface for transferring a surface shape to a molding and at least a base material supporting the transfer member. The member and the base material are joined directly or via an intermediate layer member located between them, and the joining surface of the transfer member, the joining surface of the base material, and the joining of the intermediate layer member to the transfer member At least one of the surface and the bonding surface of the intermediate layer member with the base material has a non-bonded portion that is a portion that is not directly bonded.
また、上記転写部材と上記基材とは、上記中間層部材を介して接合され、この中間層部材は、一端が上記転写部材に接合されると共に他端が上記基材に接合される複数の柱状部材を有し、上記非接合部は、上記柱状部材間の間隙である構成とするとよい。 Further, the transfer member and the base material are joined via the intermediate layer member, and the intermediate layer member has a plurality of one ends joined to the transfer member and the other end joined to the base material. It is good to have a structure which has a columnar member and the said non-joining part is a gap | interval between the said columnar members.
また、上記転写部材と上記基材とは、上記中間層部材を介して接合され、上記中間層部材は、一端が上記転写部材に接合されると共に他端が上記基材に接合される１又は２以上の円筒部材を有し、上記非接合部は、上記円筒部材の内側に形成される間隙である構成とするとよい。 Further, the transfer member and the base material are joined via the intermediate layer member, and the intermediate layer member has one end joined to the transfer member and the other end joined to the base material 1 or It is good to have a structure which has a 2 or more cylindrical member and the said non-joining part is the gap | interval formed inside the said cylindrical member.
また、上記転写部材の接合面、上記基材の接合面、上記中間層部材の上記転写部材との接合面、及び、上記中間層部材の上記基材との接合面、の中の少なくとも１面は、凹凸面に形成され、上記非接合部は、上記凹凸面の凹部である構成とするとよい。 Further, at least one of the bonding surface of the transfer member, the bonding surface of the base material, the bonding surface of the intermediate layer member with the transfer member, and the bonding surface of the intermediate layer member with the base material Is formed on the concavo-convex surface, and the non-joining portion is preferably a concave portion of the concavo-convex surface.
本発明では、転写部材と基材との間のいずれかの接合面に非接合部を設けている。そのため、転写部材の線膨張係数と素材の線膨張係数とが異なることに起因して加熱時に生じる熱応力を弱めて、主に転写部材に生じるクラック、及び接合の剥がれを防止することができる。よって、本発明によれば、加熱時における成形型の割れを抑えることができる。 In the present invention, a non-joining portion is provided on any joint surface between the transfer member and the substrate. Therefore, it is possible to weaken the thermal stress generated during heating due to the difference between the linear expansion coefficient of the transfer member and the linear expansion coefficient of the material, and to prevent cracks mainly generated in the transfer member and peeling of the joint. Therefore, according to this invention, the crack of the shaping | molding die at the time of a heating can be suppressed.
以下、本発明の実施の形態に係る成形型について、図面を参照しながら説明する。
図１は、本発明の第１実施形態に係る成形型を示す断面図である。また、図２は、上記成形型の中間層部材を示す斜視図である。
Hereinafter, a mold according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a mold according to the first embodiment of the present invention. FIG. 2 is a perspective view showing an intermediate layer member of the mold.
図１において、成形型１は、不図示の被成形物に面形状を転写する転写面２ａを有する転写部材２、少なくとも転写部材２（本実施形態では更に中間層部材４）を支持する基材３、並びに、これら転写部材２及び基材３の間に位置する中間層部材４を備えている。 In FIG. 1, a mold 1 is a base material that supports a transfer member 2 having a transfer surface 2a for transferring a surface shape to a workpiece (not shown), and at least a transfer member 2 (in this embodiment, an intermediate layer member 4). 3, and an intermediate layer member 4 positioned between the transfer member 2 and the substrate 3.
本実施形態では、転写部材２としてＳ−ＢＳＬ７（オハラ社製：屈服点温度６２５℃）からなるガラスを、中間層部材４としてＳ−ＮＳＬ５（オハラ社製：屈服点温度５９６℃）からなるガラスを用いる例を説明する。なお、転写部材２及び中間層部材４も含めて材料は限定されないが、基材３としては、強度の観点から、超鋼、ステンレス鋼等の金属部材を用いることが望ましい。 In this embodiment, the transfer member 2 is made of glass made of S-BSL7 (made by OHARA: yield point temperature 625 ° C.), and the intermediate layer member 4 is made of glass made of S-NSL5 (made by OHARA: yield point temperature 596 ° C.). An example of using will be described. The material including the transfer member 2 and the intermediate layer member 4 is not limited, but it is desirable to use a metal member such as super steel or stainless steel as the base material 3 from the viewpoint of strength.
中間層部材４は、図２に示すように、複数の柱状部材としての円柱部材４ａから構成されている。そして、中間層部材４は、各円柱部材４ａの一端である上面の接合面４ｂにおいて転写部材２の接合面２ｂと接合されている。また、中間層部材４は、各円柱部材４ａの他端である下面の接合面４ｃにおいて基材の接合面３ａと接合されている。 As shown in FIG. 2, the intermediate layer member 4 includes a cylindrical member 4 a as a plurality of columnar members. And the intermediate | middle layer member 4 is joined to the joining surface 2b of the transfer member 2 in the joining surface 4b of the upper surface which is one end of each cylindrical member 4a. Moreover, the intermediate | middle layer member 4 is joined to the joint surface 3a of a base material in the joint surface 4c of the lower surface which is the other end of each cylindrical member 4a.
ここで、中間層部材４の転写部材２及び基材３との接合面には、各円柱部材４ａの転写部材２及び基材３との接合面４ｂ，４ｃに加え、各円柱部材４ａ間の間隙からなる非接合部４ｄ，４ｅが含まれているものとする。 Here, the joining surface of the intermediate layer member 4 to the transfer member 2 and the base material 3 includes the joining surfaces 4b and 4c of the cylindrical member 4a to the transfer member 2 and the base material 3, and between the cylindrical members 4a. It is assumed that non-joining portions 4d and 4e made of a gap are included.
なお、円柱部材４ａの個数、各円柱部材４ａ間の間隔、中間層部材４の接合面における各円柱部材４ａの接合面４ｂ，４ｃ（又は非接合部）の面積割合等は、成形される被成形物の性質、中間層部材４の材質等から適宜決定されればよい。また、本実施の形態では、柱状部材として円柱状の円柱部材４ａを用いたが、角柱状の部材を用いてもよい。 The number of cylindrical members 4a, the spacing between the cylindrical members 4a, the area ratio of the joining surfaces 4b and 4c (or non-joined portions) of the cylindrical members 4a in the joining surface of the intermediate layer member 4 and the like are as follows. What is necessary is just to determine suitably from the property of a molded object, the material of the intermediate | middle layer member 4, etc. FIG. In the present embodiment, the columnar member 4a is used as the columnar member, but a prismatic member may be used.
図３は、上記成形型の製造方法を説明するための説明図である。
まず、同図に示すように、基材３の外周面に胴型５を配設すると共に、胴型５の外周面に、円環状のヒータ６ａ，６ｂが埋設された加熱部材６を配設する。そして、基材３上に中間層４を構成する円柱部材４ａを載置する。
FIG. 3 is an explanatory diagram for explaining a method of manufacturing the mold.
First, as shown in the figure, the body mold 5 is disposed on the outer peripheral surface of the substrate 3, and the heating member 6 in which the annular heaters 6 a and 6 b are embedded is disposed on the outer peripheral surface of the body mold 5. To do. Then, the cylindrical member 4 a constituting the intermediate layer 4 is placed on the base material 3.
なお、基材３上には円柱部材４ａに嵌合する穴を形成しておくとよい。このようにすることで、円柱部材４ａの基材３上への載置の安定性、及び円柱部材４ａと基材３との融着性が増す。 In addition, it is good to form the hole fitted to the cylindrical member 4a on the base material 3. FIG. By doing in this way, the stability of mounting the cylindrical member 4a on the base material 3 and the fusion property between the cylindrical member 4a and the base material 3 are increased.
次に、胴型５内を摺動可能な加圧型７を不図示の加圧手段により降下させ、同図に示すように、転写部材２の転写面２ａに当接させる。この状態で、加熱部材６（ヒータ６ａ，６ｂ）により、胴型５を介して転写部材２及び中間層部材４を加熱する。 Next, the pressure die 7 slidable in the body die 5 is lowered by a pressure means (not shown) and brought into contact with the transfer surface 2a of the transfer member 2 as shown in FIG. In this state, the transfer member 2 and the intermediate layer member 4 are heated by the heating member 6 (heaters 6a and 6b) through the body mold 5.
そして、転写部材２が屈服点温度（６２５℃）を超えた後に、加圧型７により加圧を開始する。なお、転写部材２の成形温度において中間層部材４が軟化すると、中間層部材４を構成する各円柱部材４ａが互いに融着しやすいため、中間層部材４には転写部材２の成形温度において軟化しない材料を用いることが望ましい。 Then, after the transfer member 2 exceeds the bending point temperature (625 ° C.), pressurization is started by the pressurization die 7. When the intermediate layer member 4 is softened at the molding temperature of the transfer member 2, the cylindrical members 4 a constituting the intermediate layer member 4 are easily fused to each other. Therefore, the intermediate layer member 4 is softened at the molding temperature of the transfer member 2. It is desirable to use materials that do not.
転写部材２と中間層部材４との接合、基材３と中間層部材４との接合、転写部材２（成形型１）への加圧等が終了した後には、加熱部材６（ヒータ６ａ，６ｂ）による加熱を停止し、冷却を開始する。本実施形態では、自然冷却により転写部材２等を冷却するが、冷風、油等の冷却媒体を用いることで冷却時間を短縮することも可能である。 After the joining of the transfer member 2 and the intermediate layer member 4, the joining of the base material 3 and the intermediate layer member 4, the pressurization to the transfer member 2 (molding die 1), etc., the heating member 6 (heater 6 a, Stop heating according to 6b) and start cooling. In this embodiment, the transfer member 2 and the like are cooled by natural cooling. However, the cooling time can be shortened by using a cooling medium such as cold air or oil.
以上のようにして図１に示す成形型１が製造（成形）される。なお、中間層部材４を円柱部材４ａで構成したため、円柱部材４ａ間の間隙によって各円柱部材４ａがしなり、応力を分散することになる。これによって、加圧型７により形成される転写部材２の転写面２ａが所望の形状と異なる場合があるが、変形を見込んで加圧型７に補正加工をしておけばよい。上記の転写面２ａの変形は、実成形による成形型１を測定して、補正してもよいが、シミュレーションにより予め予測して形状を補正することも可能である。 As described above, the mold 1 shown in FIG. 1 is manufactured (molded). In addition, since the intermediate | middle layer member 4 was comprised by the cylindrical member 4a, each cylindrical member 4a is bent by the gap | interval between the cylindrical members 4a, and a stress is disperse | distributed. As a result, the transfer surface 2a of the transfer member 2 formed by the pressing die 7 may be different from the desired shape, but the pressing die 7 may be corrected in anticipation of deformation. The deformation of the transfer surface 2a may be corrected by measuring the molding die 1 by actual molding, but it is also possible to correct the shape by predicting in advance by simulation.
また、同図では、加圧型７により加圧されて形成される転写部材２の転写面２ａを平面であるかのように図示しているが、転写面２ａの面形状は、凹面、凸面、フレネル面、アレイ面等のその他の面形状であっても何ら問題ない。 In addition, in the drawing, the transfer surface 2a of the transfer member 2 formed by being pressed by the pressing die 7 is illustrated as if it is a plane, but the surface shape of the transfer surface 2a is concave, convex, Other surface shapes such as a Fresnel surface and an array surface are not a problem.
以上説明した第１実施形態では、中間層部材４の転写部材２及び基材３との接合面に、円柱部材４ａ間の間隙からなる非接合部４ｄ，４ｅを設けている。そのため、転写部材２の線膨張係数と基材３の線膨張係数とが異なることに起因して加熱時に生じる熱応力を弱めて、主に転写部材２に生じるクラック、及び接合の剥がれを防止することができる。よって、本実施形態によれば、加熱時における成形型１の割れを抑えることができる。 In the first embodiment described above, the non-joined portions 4d and 4e formed by the gaps between the cylindrical members 4a are provided on the joint surface between the intermediate layer member 4 and the transfer member 2 and the base material 3. For this reason, the thermal stress generated during heating due to the difference between the linear expansion coefficient of the transfer member 2 and the linear expansion coefficient of the base material 3 is weakened, and cracks generated mainly in the transfer member 2 and peeling of the joint are prevented. be able to. Therefore, according to this embodiment, the crack of the shaping | molding die 1 at the time of a heating can be suppressed.
また、本実施形態では、中間層部材４を複数の円柱部材４ａで構成したため、各円柱部材４ａがしなりを持ち応力を分散するので、より有効に熱応力を弱めることができる。したがって、加熱時における成形型１の割れをより一層抑えることができる。 Moreover, in this embodiment, since the intermediate | middle layer member 4 was comprised with the some cylindrical member 4a, since each cylindrical member 4a has bending and disperse | distributes stress, it can weaken a thermal stress more effectively. Accordingly, it is possible to further suppress cracking of the mold 1 during heating.
図４は、本発明の第２実施形態に係る中間層部材を示す斜視図である。
本実施形態は、中間層部材１４の構成のみ上記第１実施形態と相違するため、詳細な説明は省略する。
FIG. 4 is a perspective view showing an intermediate layer member according to the second embodiment of the present invention.
Since this embodiment is different from the first embodiment only in the configuration of the intermediate layer member 14, a detailed description thereof will be omitted.
図４において、中間層部材１４は、１又は２以上の円筒部材としての、２つの円筒部材１４ａ，１４ｂから構成されている。中間層部材１４は、上記第１実施形態において説明したように、図３に示す胴型５、加熱部材６、加圧型７等により、図１に示すように成形型１が製造（成形）される。ここで、本実施形態に係る非接合部は、外側に位置する円筒部材１４ａと内側に位置する円筒部材１４ｂとの間の間隙Ｓ１及び内側に位置する円筒部材１４ｂの内側の間隙Ｓ２からなる。 In FIG. 4, the intermediate | middle layer member 14 is comprised from the two cylindrical members 14a and 14b as one or two or more cylindrical members. As described in the first embodiment, the intermediate layer member 14 is manufactured (molded) as shown in FIG. 1 by the barrel mold 5, the heating member 6, the pressurizing mold 7 and the like shown in FIG. The Here, the non-joining portion according to the present embodiment includes a gap S1 between the cylindrical member 14a located outside and the cylindrical member 14b located inside, and a gap S2 inside the cylindrical member 14b located inside.
なお、円筒部材１４ａ，１４ｂの個数、各円筒部材１４ａ，１４ｂ間の間隔、中間層部材１４の接合面における円筒部材１４ａ，１４ｂの接合面（又は間隙Ｓ１，Ｓ２）の面積割合等は、成形される被成形物の性質、中間層部材１４の材質等から適宜決定されればよい。 The number of cylindrical members 14a and 14b, the distance between the cylindrical members 14a and 14b, the area ratio of the joining surfaces (or gaps S1 and S2) of the cylindrical members 14a and 14b to the joining surface of the intermediate layer member 14, etc. What is necessary is just to determine suitably from the property of the to-be-molded object performed, the material of the intermediate | middle layer member 14, etc.
本実施形態によれば、外側に位置する円筒部材１４ａと内側に位置する円筒部材１４ｂとの間の間隙Ｓ１及び内側に位置する円筒部材１４ｂの内側の間隙Ｓ２からなる非接合部により、上記第１実施形態と同様に、加熱時における成形型の割れを抑えることができる。 According to this embodiment, the non-joint portion including the gap S1 between the outer cylindrical member 14a and the inner cylindrical member 14b and the inner gap S2 of the inner cylindrical member 14b is used to As in the first embodiment, it is possible to suppress cracking of the mold during heating.
また、円筒部材１４ａ，１４ｂにより中間層部材１４を構成するため、円筒部材１４ａ，１４ｂにおける図１に示す転写部材或いは基材との接合面積を増やすことが可能であり、接合強度を高めることができる。したがって、加熱時における成形型の割れをより有効に抑えることができる。 Further, since the intermediate layer member 14 is constituted by the cylindrical members 14a and 14b, it is possible to increase the bonding area of the cylindrical members 14a and 14b with the transfer member or the base material shown in FIG. 1 and increase the bonding strength. it can. Therefore, it is possible to more effectively suppress cracking of the mold during heating.
図５は、本発明の第３実施形態に係る中間層部材を示す斜視図である。
本実施形態は、上記第２実施形態と同様に、中間層部材２４の構成のみ上記第１実施形態と相違するため、詳細な説明は省略する。
FIG. 5 is a perspective view showing an intermediate layer member according to the third embodiment of the present invention.
Similar to the second embodiment, the present embodiment is different from the first embodiment only in the configuration of the intermediate layer member 24, and a detailed description thereof will be omitted.
図５において、中間層部材２４は、図１に示す転写部材２との接合面２４ａ、及び、基材３との接合面２４ｂ（同図では見えない）が凹凸面に形成されている。これら凹凸面は、所望の接合強度を考慮して、例えばエッチング、研削等により形成することが可能である。ここで、本実施形態では、凹凸面（接合面２４ａ，２４ｂ）の凹部が転写部材２或いは基材３に接合されない非接合部となっている。 In FIG. 5, the intermediate layer member 24 is formed with an uneven surface with a joint surface 24 a with the transfer member 2 shown in FIG. 1 and a joint surface 24 b with the base material 3 (not visible in the same figure). These concavo-convex surfaces can be formed by, for example, etching, grinding, or the like in consideration of desired bonding strength. Here, in the present embodiment, the concave portions of the uneven surfaces (joint surfaces 24 a and 24 b) are non-joined portions that are not joined to the transfer member 2 or the base material 3.
なお、凹凸間の間隔（高さ）、中間層部材２４の接合面における凹部の面積の割合等については、図１に示す転写部材２（又は基材３）が接合時に凹部を完全に埋めない範囲で（即ち、非接合部としての凹部を残せる範囲で）、成形される被成形物の性質、中間層部材２４の材質等から適宜決定されればよい。 In addition, about the space | interval (height) between unevenness | corrugations, the ratio of the area of the recessed part in the joining surface of the intermediate | middle layer member 24, etc., the transcription | transfer member 2 (or base material 3) shown in FIG. It may be appropriately determined within the range (that is, within a range in which a concave portion as a non-joining portion can be left) from the properties of the molded article to be molded, the material of the intermediate layer member 24, and the like.
本実施形態によれば、中間層部材２４の接合面２４ａ，２４ｂの凹部が非接合部となっているため、上記第１実施形態と同様に、加熱時における成形型の割れを抑えることができる。 According to the present embodiment, since the concave portions of the joining surfaces 24a and 24b of the intermediate layer member 24 are non-joined portions, cracking of the mold during heating can be suppressed as in the first embodiment. .
また、本実施形態によれば、中間層部材２４を１つの部材から形成したため、成形型の構成が簡略化される。
なお、中間層部材２４の接合面２４ａ，２４ｂを凹凸面としなくとも、溝等の凹部を形成することで、加熱時における成形型の割れを抑えることができる。上記の凹部としては、接合強度を考慮して適宜決定すればよいが、例えば図１に示す転写部材２（成形する光学素子）が回転軸対称である場合には、切削等の手段で同心状の溝を形成するとよい。
Moreover, according to this embodiment, since the intermediate | middle layer member 24 was formed from one member, the structure of a shaping | molding die is simplified.
In addition, even if it does not make the joining surfaces 24a and 24b of the intermediate | middle layer member 24 uneven | corrugated surface, the crack of the shaping | molding die at the time of a heating can be suppressed by forming recessed parts, such as a groove | channel. The concave portion may be appropriately determined in consideration of the bonding strength. For example, when the transfer member 2 (molding optical element) shown in FIG. 1 is rotationally symmetric, it is concentric by means such as cutting. It is preferable to form a groove.
また、本実施形態では、中間層部材２４の両側の接合面２４ａ，２４ｂそれぞれに凹凸面を形成したが、中間層部材２４が図１に示す転写部材２の線膨張係数と近いガラス材料等から構成される場合には、中間層部材２４と転写部材２との間に発生する熱応力は緩和されるので、基材３との接合面２４ｂにのみ応力緩和のための凹部を設ければよい。 Further, in this embodiment, the concave and convex surfaces are formed on the joint surfaces 24a and 24b on both sides of the intermediate layer member 24. However, the intermediate layer member 24 is made of a glass material or the like close to the linear expansion coefficient of the transfer member 2 shown in FIG. In the case of being configured, the thermal stress generated between the intermediate layer member 24 and the transfer member 2 is relieved, and therefore a recess for relieving the stress may be provided only on the joint surface 24b with the base material 3. .
以上説明した第１〜第３実施形態では、中間層部材４，１４，２４側に非接合部を設ける例を説明したが、中間層部材を設けずに、図１に示す転写部材２或いは基材３の接合面２ｂ，３ａに上記の凹部等による非接合部を設けることでも本発明の効果を得ることは可能である。 In the first to third embodiments described above, the example in which the non-joining portion is provided on the intermediate layer members 4, 14, and 24 has been described. However, the transfer member 2 or the base shown in FIG. The effect of the present invention can also be obtained by providing non-joined portions such as the above-described recesses on the joining surfaces 2b and 3a of the material 3.
また、上記第１実施形態及び第２実施形態で説明した、円柱部材４ａから構成される中間層部材４、及び円筒部材１４ａ，１４ｂから構成される中間層部材１４の接合面に、上記第３実施形態で説明した凹部を設けることで、有効に成形型１の割れを抑えることも可能である。 In addition, the third layer described above is connected to the joint surface of the intermediate layer member 4 formed of the columnar member 4a and the intermediate layer member 14 formed of the cylindrical members 14a and 14b described in the first embodiment and the second embodiment. By providing the concave portion described in the embodiment, it is possible to effectively suppress cracking of the mold 1.
