Abstract
Description
本発明は、車両用樹脂部材成形装置に関する。 The present invention relates to a vehicle resin member molding apparatus.
下記特許文献１に開示された成形型装置では、上型に真空吸引孔が形成されている。真空吸引孔は、上型の型面側で開口しており、表皮材が上型の型面に対して対向された状態で真空ポンプが作動されると、表皮材が上型の型面にける真空吸引孔の形成部分に吸着されて保持される。また、この成形型装置では、型締め状態で下型側から合成樹脂材が供給される。下型における合成樹脂材の供給部分は、上型における表皮材の配置部分に対向されており、供給された合成樹脂材の圧力は、表皮材を上型の型面へ押し付ける。これによって、表皮材の位置ずれ等の発生が抑制される。 In the molding apparatus disclosed in Patent Document 1 below, a vacuum suction hole is formed in the upper mold. The vacuum suction hole is opened on the mold surface side of the upper mold, and when the vacuum pump is operated with the skin material facing the mold surface of the upper mold, the skin material becomes the mold surface of the upper mold. It is attracted and held by the formed portion of the vacuum suction hole. Further, in this molding apparatus, the synthetic resin material is supplied from the lower mold side in the molded state. The supply portion of the synthetic resin material in the lower mold faces the arrangement portion of the skin material in the upper mold, and the pressure of the supplied synthetic resin material presses the skin material against the mold surface of the upper mold. As a result, the occurrence of misalignment of the skin material is suppressed.
ところで、このような成形型装置では、下型における合成樹脂材の供給部分と、上型における表皮材の配置部分とが上型と下型との対向方向に対する直交方向にずれていると、成形型装置内で上型と下型との対向方向に対して交差する方向に流れる合成樹脂材によって表皮材が押圧されて表皮材の位置ずれが生じる可能性がある。 By the way, in such a molding apparatus, if the supply portion of the synthetic resin material in the lower mold and the arrangement portion of the skin material in the upper mold are displaced in the direction orthogonal to the facing direction of the upper mold and the lower mold, molding is performed. There is a possibility that the skin material is pressed by the synthetic resin material flowing in the direction intersecting the opposite directions of the upper mold and the lower mold in the mold device, and the position of the skin material is displaced.
本発明は、上記事実を考慮して、第２成形素材の位置ずれの発生を抑制できる車両用樹脂部材成形装置を得ることが目的である。 In consideration of the above facts, an object of the present invention is to obtain a vehicle resin member molding apparatus capable of suppressing the occurrence of misalignment of the second molding material.
請求項１に記載の車両用樹脂部材成形装置は、型締め状態で内側の型面によって第１成形素材を成形すると共に、前記型面で開口する凹部が形成された金型と、前記型面側の面が前記型面に対して前記凹部の深さ方向側にずれた状態で前記凹部の内側に設けられると共に、前記型面側と前記型面側とは異なる側との間で通気可能とされ、前記型面側に第２成形素材が配置される通気型部材と、前記通気型部材における前記型面側とは異なる側から空気を吸引する吸引装置と、を備えている。 The vehicle resin member molding apparatus according to claim 1 has a mold in which a first molding material is molded by an inner mold surface in a mold-clamped state, a mold having a recess opened in the mold surface, and the mold surface. The side surface is provided inside the recess in a state of being displaced from the mold surface toward the depth direction of the recess, and ventilation is possible between the mold surface side and a side different from the mold surface side. It is provided with a ventilation type member in which the second molding material is arranged on the mold surface side, and a suction device for sucking air from a side of the ventilation type member different from the mold surface side.
請求項１に記載の車両用樹脂部材成形装置では、通気型部材における金型の型面側に第２成形素材が配置される。この状態で、金型の内側に第１成形素材が供給され、金型の内側への第１成形素材が供給に前後して金型が型締めされる。これによって第１成形素材と第２成形素材とが一体になり、第１成形素材及び第２成形素材が成形されて車両用樹脂部材が形成される。 In the vehicle resin member molding apparatus according to claim 1, the second molding material is arranged on the mold surface side of the mold in the ventilation mold member. In this state, the first molding material is supplied to the inside of the mold, and the mold is fastened before and after the supply of the first molding material to the inside of the mold. As a result, the first molding material and the second molding material are integrated, and the first molding material and the second molding material are molded to form a resin member for a vehicle.
また、通気型部材における金型の型面側に第２成形素材が配置された状態で吸引装置が作動すると、通気型部材における型面側とは異なる側から空気が吸引装置によって吸引される。通気型部材は、型面側と型面側とは異なる側との間で通気可能とされる。このため、吸引装置が作動されると、通気型部材における型面側から型面側とは異なる側へ空気が吸引される。これによって、通気型部材の型面側で負圧が生じ、第２成形素材が通気型部材に密着するように通気型部材に保持される。 Further, when the suction device is operated with the second molding material arranged on the mold surface side of the mold of the ventilation mold member, air is sucked by the suction device from a side different from the mold surface side of the ventilation mold member. The ventilation type member is made capable of ventilation between the mold surface side and the side different from the mold surface side. Therefore, when the suction device is operated, air is sucked from the mold surface side of the ventilation mold member to a side different from the mold surface side. As a result, a negative pressure is generated on the mold surface side of the ventilation type member, and the second molding material is held by the ventilation type member so as to be in close contact with the ventilation type member.
ここで、通気型部材における型面側の面は、型面に対して金型の凹部の深さ方向側にずれている。このため、通気型部材に保持された第２成形素材の少なくとも一部は、金型の凹部の周面と対向している。このため、通気型部材に保持された第２成形素材が金型の凹部の深さ方向に対して交差する方向側へ移動しようとした場合、このような第２成形素材の移動は、金型の凹部の周面によって制限される。 Here, the surface of the ventilation mold member on the mold surface side is deviated from the mold surface toward the depth direction of the recess of the mold. Therefore, at least a part of the second molding material held by the ventilation mold member faces the peripheral surface of the concave portion of the mold. Therefore, when the second molding material held by the ventilation mold member tries to move in the direction in which it intersects with the depth direction of the concave portion of the mold, such movement of the second molding material is performed on the mold. It is limited by the peripheral surface of the recess.
以上、説明したように、請求項１に記載の車両用樹脂部材成形装置では、吸引装置の吸引による通気型部材の第２成形素材の保持と、金型の凹部の周面による第２成形素材の移動制限とによって、第２成形素材が通気型部材上の所定位置から移動すること、すなわち、第２成形素材の位置ずれの発生を効果的に抑制できる。 As described above, in the vehicle resin member molding apparatus according to claim 1, the holding of the second molding material of the ventilation mold member by the suction of the suction device and the second molding material by the peripheral surface of the concave portion of the mold. By limiting the movement of the second molding material, it is possible to effectively suppress the movement of the second molding material from a predetermined position on the ventilation mold member, that is, the occurrence of misalignment of the second molding material.
次に、本発明の実施の形態を図１から図４の各図に基づいて説明する。 Next, an embodiment of the present invention will be described with reference to the respective drawings of FIGS. 1 to 4.
＜本実施の形態の構成＞
図１に示されるように、本実施の形態に係る車両用樹脂部材成形装置１０は、金型１２を備えている。金型１２は、下型１４及び上型１６を含んで構成されている。下型１４には、上型１６側へ開口した凹形状のキャビティ部１８が形成されており、キャビティ部１８の内側面が金型１２の型面を構成している。これに対して、上型１６には、下型１４側へ向けて凸状のコア部２０が形成されており、コア部２０の表面が金型１２の型面を構成している。金型１２の型締め状態では、上型１６のコア部２０が、下型１４のキャビティ部１８の内側に入る。概ね、コア部２０の表面とキャビティ部１８の内面とによって成形品２２の外形状が形成される。下型１４のキャビティ部１８上には、成形品２２の本体部分を形成するための第１成形素材としての主基材２４が配置される。主基材２４は、例えば、ガラス繊維や炭素繊維等によって形成された連続繊維を含んで構成される繊維強化樹脂材とされている。
<Structure of the present embodiment>
As shown in FIG. 1, the vehicle resin member molding apparatus 10 according to the present embodiment includes a mold 12. The mold 12 is configured to include a lower mold 14 and an upper mold 16. The lower mold 14 is formed with a concave cavity portion 18 that opens toward the upper mold 16 side, and the inner surface surface of the cavity portion 18 constitutes the mold surface of the mold 12. On the other hand, the upper mold 16 is formed with a core portion 20 having a convex shape toward the lower mold 14, and the surface of the core portion 20 constitutes the mold surface of the mold 12. In the mold-fastened state of the mold 12, the core portion 20 of the upper mold 16 enters the inside of the cavity portion 18 of the lower mold 14. Generally, the outer shape of the molded product 22 is formed by the surface of the core portion 20 and the inner surface of the cavity portion 18. A main base material 24 as a first molding material for forming the main body portion of the molded product 22 is arranged on the cavity portion 18 of the lower mold 14. The main base material 24 is, for example, a fiber-reinforced resin material composed of continuous fibers formed of glass fibers, carbon fibers, or the like.
下型１４には、１乃至複数の凹部２６が形成されている。凹部２６は、キャビティ部１８にて開口されている。また、下型１４には、通気部２８が形成されている。通気部２８の一端は、凹部２６の底面で開口されており、通気部２８の他端は、下型１４の外周部で開口されている。通気部２８の他端には、通気パイプ３０が接続されている。通気パイプ３０は、吸引ポンプ３２へ接続されており、吸引ポンプ３２が作動されると、通気パイプ３０及び通気部２８を介して凹部２６の内側の空気が吸引ポンプ３２によって吸引される。 The lower mold 14 is formed with one or more recesses 26. The recess 26 is opened at the cavity 18. Further, the lower mold 14 is formed with a ventilation portion 28. One end of the ventilation portion 28 is opened at the bottom surface of the recess 26, and the other end of the ventilation portion 28 is opened at the outer peripheral portion of the lower mold 14. A ventilation pipe 30 is connected to the other end of the ventilation portion 28. The ventilation pipe 30 is connected to the suction pump 32, and when the suction pump 32 is operated, the air inside the recess 26 is sucked by the suction pump 32 via the ventilation pipe 30 and the ventilation portion 28.
また、凹部２６の内側にはポーラス型３４が設けられている。ポーラス型３４は、多孔質状に形成されている。このため、空気は、ポーラス型３４の外部からポーラス型３４の内部を通ってポーラス型３４の外部へ出ることができる。ポーラス型３４の外周形状は、概ね、凹部２６の内周形状と同じ形状とされており、ポーラス型３４が凹部２６の内側に配置された状態では、ポーラス型３４においてキャビティ部１８側の面であるポーラス型面３６を除いたポーラス型３４の外周面が凹部２６の内側面へ接する。 Further, a porous type 34 is provided inside the recess 26. The porous type 34 is formed in a porous shape. Therefore, air can flow from the outside of the porous type 34 to the outside of the porous type 34 through the inside of the porous type 34. The outer peripheral shape of the porous type 34 is substantially the same as the inner peripheral shape of the concave portion 26, and when the porous type 34 is arranged inside the concave portion 26, the surface of the porous type 34 on the cavity 18 side. The outer peripheral surface of the porous mold 34 excluding a certain porous mold surface 36 is in contact with the inner surface of the recess 26.
一方、ポーラス型３４のポーラス型面３６は、キャビティ部１８の内側面（型面）に対して凹部２６の深さ方向側（凹部２６におけるキャビティ部１８とは反対方向側）へずれている。このため、凹部２６の内周部の一部は、ポーラス型面３６よりもキャビティ部１８側へ位置する。後述するように、ポーラス型面３６上には、第２成形素材としてのシート状の補強パッチ３８が配置される。補強パッチ３８は、例えば、ガラス繊維や炭素繊維等によって形成された短繊維又は長繊維による非連続繊維を含んで構成される繊維強化樹脂材とされている。ここで、凹部２６の深さ方向に沿ったキャビティ部１８の内側面（型面）とポーラス型面３６と間の段差は、補強パッチ３８の厚さ寸法と概ね等しくなるようにポーラス型３４の形状等が設定されている。 On the other hand, the porous mold surface 36 of the porous mold 34 is deviated from the inner surface (mold surface) of the cavity portion 18 toward the depth direction side of the recess 26 (the side opposite to the cavity portion 18 in the recess 26). Therefore, a part of the inner peripheral portion of the recess 26 is located closer to the cavity 18 than the porous mold surface 36. As will be described later, a sheet-shaped reinforcing patch 38 as a second molding material is arranged on the porous mold surface 36. The reinforcing patch 38 is, for example, a fiber-reinforced resin material composed of discontinuous fibers made of short fibers or long fibers formed of glass fibers, carbon fibers, or the like. Here, the step between the inner surface (mold surface) of the cavity portion 18 and the porous mold surface 36 along the depth direction of the recess 26 is substantially equal to the thickness dimension of the reinforcing patch 38 of the porous mold 34. The shape etc. are set.
さらに、図２に示されるように、本車両用樹脂部材成形装置１０は、搬送装置４０を備えている。搬送装置４０は、保持部４２を備えている。保持部４２は、円錐台形状や四角錐台形状等の錐台形状とされている。保持部４２には、噴出孔４４が形成されている。噴出孔４４の一端は、保持部４２の一端の略中央で開口されている。これに対して、噴出孔４４の他端は、空気送給装置（図示省略）へ接続されている。空気供給装置は、例えば、エアコンプレッサ又は標準気圧よりも高い圧力の空気が貯蔵されたタンク等とされており、空気が空気供給装置から保持部４２へ送られると、空気が保持部４２の一端から噴出される。 Further, as shown in FIG. 2, the resin member molding device 10 for this vehicle includes a transport device 40. The transport device 40 includes a holding unit 42. The holding portion 42 has a truncated cone shape such as a truncated cone shape or a quadrangular truncated cone shape. A ejection hole 44 is formed in the holding portion 42. One end of the ejection hole 44 is opened substantially at the center of one end of the holding portion 42. On the other hand, the other end of the ejection hole 44 is connected to an air feeding device (not shown). The air supply device is, for example, an air compressor or a tank in which air having a pressure higher than the standard atmospheric pressure is stored. When air is sent from the air supply device to the holding section 42, air is sent to one end of the holding section 42. Is ejected from.
また、保持部４２には、複数の吸引孔４６が形成されている。吸引孔４６は、保持部４２における噴出孔４４の径方向外側で、保持部４２の周方向に所定の間隔をおいて形成されている。吸引孔４６の一端は、保持部４２の一端で開口されている。これに対して、吸引孔４６の他端は、ポンプ（図示省略）へ接続されている。ポンプが作動されると、吸引孔４６の一端から空気が吸い込まれる。このため、例えば、保持部４２の一端が補強パッチ３８の近傍で補強パッチ３８の厚さ方向に補強パッチ３８と対向された状態でポンプが作動すると、補強パッチ３８が吸引されて、保持部４２の一端で補強パッチ３８の外周部近傍部分が保持部４２によって保持される。 Further, a plurality of suction holes 46 are formed in the holding portion 42. The suction holes 46 are formed on the radial side of the ejection holes 44 in the holding portion 42 at predetermined intervals in the circumferential direction of the holding portion 42. One end of the suction hole 46 is opened at one end of the holding portion 42. On the other hand, the other end of the suction hole 46 is connected to a pump (not shown). When the pump is operated, air is sucked from one end of the suction hole 46. Therefore, for example, when the pump operates with one end of the holding portion 42 facing the reinforcing patch 38 in the thickness direction of the reinforcing patch 38 in the vicinity of the reinforcing patch 38, the reinforcing patch 38 is sucked and the holding portion 42 is sucked. The portion near the outer peripheral portion of the reinforcing patch 38 is held by the holding portion 42 at one end of the reinforcing patch 38.
この保持部４２の他端側は、例えば、アーム（図示省略）に連結されている。アームは、モータの駆動軸（図示省略）に接続されており、モータの駆動力によって三次元的に移動できる。主基材２４や補強パッチ３８の仮置場で主基材２４や補強パッチ３８が保持部４２によって保持される。この状態で、保持部４２が下型１４のキャビティ部１８上での主基材２４や補強パッチ３８の配置位置まで移動される。主基材２４や補強パッチ３８の配置位置で保持部４２による主基材２４や補強パッチ３８の保持が解消されることによって主基材２４や補強パッチ３８が配置位置に配置される。 The other end side of the holding portion 42 is connected to, for example, an arm (not shown). The arm is connected to the drive shaft of the motor (not shown) and can move three-dimensionally by the drive force of the motor. The main base material 24 and the reinforcing patch 38 are held by the holding portion 42 in the temporary storage place of the main base material 24 and the reinforcing patch 38. In this state, the holding portion 42 is moved to the arrangement position of the main base material 24 and the reinforcing patch 38 on the cavity portion 18 of the lower mold 14. The main base material 24 and the reinforcing patch 38 are arranged at the arrangement position by eliminating the holding of the main base material 24 and the reinforcing patch 38 by the holding portion 42 at the arrangement position of the main base material 24 and the reinforcing patch 38.
＜本実施の形態の作用、効果＞
次に、本車両用樹脂部材成形装置１０での成形品２２の成形工程の説明を通して本実施の形態の作用並びに効果について説明する。なお、図１に示されるように、本実施の形態では、下型１４のキャビティ部１８に３箇所の凹部２６が形成され、これらの凹部２６の各々にポーラス型３４が設けられ、ポーラス型３４のポーラス型面３６上に補強パッチ３８が配置される構成である。しかしながら、各凹部２６への補強パッチ３８の配置等については基本的に同様の工程であるため、図２から図４を用いた各工程の説明では、１箇所の凹部２６について説明して、他の凹部２６について説明及び図示は省略する。
<Action and effect of this embodiment>
Next, the actions and effects of the present embodiment will be described through the description of the molding process of the molded product 22 in the resin member molding device 10 for this vehicle. As shown in FIG. 1, in the present embodiment, three recesses 26 are formed in the cavity 18 of the lower mold 14, and a porous mold 34 is provided in each of the recesses 26, and the porous mold 34 is provided. The reinforcing patch 38 is arranged on the porous mold surface 36 of the above. However, since the arrangement of the reinforcing patch 38 in each recess 26 is basically the same step, in the description of each step using FIGS. 2 to 4, one recess 26 will be described and the other recesses 26 will be described. The description and illustration of the recess 26 of the above are omitted.
補強パッチ配置工程では、下型１４の凹部２６に補強パッチ３８が配置される。この補強パッチ配置工程では、搬送装置４０の保持部４２によって補強パッチ３８が搬送される。図２において実線で示されるように、保持部４２の一端が下型１４の凹部２６の近傍で凹部２６と対向されると、保持部４２の吸引孔４６からの空気の吸引が停止される。これによって、保持部４２による補強パッチ３８の保持が解消される。さらに、保持部４２の噴出孔４４から空気が噴き出される。 In the reinforcing patch arranging step, the reinforcing patch 38 is arranged in the recess 26 of the lower mold 14. In this reinforcing patch arrangement step, the reinforcing patch 38 is conveyed by the holding portion 42 of the conveying device 40. As shown by a solid line in FIG. 2, when one end of the holding portion 42 faces the recess 26 in the vicinity of the recess 26 of the lower mold 14, the suction of air from the suction hole 46 of the holding portion 42 is stopped. As a result, the holding of the reinforcing patch 38 by the holding portion 42 is eliminated. Further, air is ejected from the ejection hole 44 of the holding portion 42.
これによって、補強パッチ３８が凹部２６内のポーラス型３４のポーラス型面３６側へ移動される。さらに、この状態では、吸引ポンプ３２（図１参照）が作動される。これによって、凹部２６内の空気が通気パイプ３０を通って吸引ポンプ３２に吸引される。この状態では、ポーラス型３４内を空気が流れ、ポーラス型面３６側で負圧が生じる。このため、上記のように、保持部４２の噴出孔４４からの空気の噴き出しによって凹部２６内のポーラス型面３６側へ移動された補強パッチ３８が凹部２６内に配置されて、補強パッチ３８のポーラス型３４側の面がポーラス型３４のポーラス型面３６に貼り付いて保持される（図３参照）。 As a result, the reinforcing patch 38 is moved to the porous mold surface 36 side of the porous mold 34 in the recess 26. Further, in this state, the suction pump 32 (see FIG. 1) is operated. As a result, the air in the recess 26 is sucked into the suction pump 32 through the ventilation pipe 30. In this state, air flows in the porous mold 34, and a negative pressure is generated on the porous mold surface 36 side. Therefore, as described above, the reinforcing patch 38 that has been moved to the porous mold surface 36 side in the recess 26 by the ejection of air from the ejection hole 44 of the holding portion 42 is arranged in the recess 26, and the reinforcing patch 38 is provided. The surface on the porous mold 34 side is attached to and held on the porous mold surface 36 of the porous mold 34 (see FIG. 3).
次いで、主基材配置工程では、図４に示されるように、下型１４のキャビティ部１８に主基材２４が配置される。この状態で、金型１２が型締めされると、主基材２４が成形品２２の形状にプレスされる。このプレス状態で、例えば、金型１２が加熱されて主基材２４及び補強パッチ３８を形成する合成樹脂材が加熱され、主基材２４及び補強パッチ３８を形成する合成樹脂材が加熱される。これによって、主基材２４及び補強パッチ３８を形成する合成樹脂材が硬化されると共に、主基材２４と補強パッチ３８とが一体にされる。このようにして、成形品２２が形成される。 Next, in the main base material placement step, as shown in FIG. 4, the main base material 24 is placed in the cavity portion 18 of the lower mold 14. When the die 12 is molded in this state, the main base material 24 is pressed into the shape of the molded product 22. In this pressed state, for example, the mold 12 is heated to heat the synthetic resin material forming the main base material 24 and the reinforcing patch 38, and the synthetic resin material forming the main base material 24 and the reinforcing patch 38 is heated. .. As a result, the synthetic resin material forming the main base material 24 and the reinforcing patch 38 is cured, and the main base material 24 and the reinforcing patch 38 are integrated. In this way, the molded product 22 is formed.
ところで、金型１２が型締めされると、下型１４のキャビティ部１８上の主基材２４は、上型１６のコア部２０に押圧される。これによって、主基材２４は、下型１４のキャビティ部１８上で、上型１６と下型１４との対向方向に対して交差する方向へ広がる。このように、主基材２４が広がる際には、主基材２４は、キャビティ部１８の凹部２６上を移動する。このため、主基材２４が凹部２６内に配置された補強パッチ３８へ接触すると、補強パッチ３８は、主基材２４と共に移動しようとする。 By the way, when the mold 12 is molded, the main base material 24 on the cavity portion 18 of the lower mold 14 is pressed against the core portion 20 of the upper mold 16. As a result, the main base material 24 spreads on the cavity portion 18 of the lower mold 14 in a direction intersecting the opposite directions of the upper mold 16 and the lower mold 14. In this way, when the main base material 24 expands, the main base material 24 moves on the recess 26 of the cavity portion 18. Therefore, when the main base material 24 comes into contact with the reinforcing patch 38 arranged in the recess 26, the reinforcing patch 38 tends to move together with the main base material 24.
ここで、補強パッチ３８は、下型１４の凹部２６の内側におけるポーラス型３４のポーラス型面３６上に配置される。金型１２が型締めされる際には、吸引ポンプ３２が作動されており、補強パッチ３８のポーラス型３４側の面は、ポーラス型３４のポーラス型面３６に貼り付いて保持される。これによって、補強パッチ３８の移動が抑制される。 Here, the reinforcing patch 38 is arranged on the porous mold surface 36 of the porous mold 34 inside the recess 26 of the lower mold 14. When the mold 12 is molded, the suction pump 32 is operated, and the surface of the reinforcing patch 38 on the porous mold 34 side is attached to and held on the porous mold surface 36 of the porous mold 34. As a result, the movement of the reinforcing patch 38 is suppressed.
しかも、下型１４のキャビティ部１８の表面と、ポーラス型３４のポーラス型面３６との間には段差が形成されており、補強パッチ３８が凹部２６の内側でポーラス型３４のポーラス型面３６に貼り付いた状態では、補強パッチ３８の外周部と、凹部２６の内周部におけるポーラス型３４のポーラス型面３６よりもキャビティ部１８側の部分とが対向している。このため、下型１４のキャビティ部１８の表面上を移動する主基材２４が、補強パッチ３８のポーラス型面３６とは反対側の面へ接触し、これによって、補強パッチ３８が主基材２４の移動方向側へ引っ張られて移動しようとすると、凹部２６の内周部における補強パッチ３８の外周部との対向部分が、補強パッチ３８の移動を制限する。 Moreover, a step is formed between the surface of the cavity portion 18 of the lower mold 14 and the porous mold surface 36 of the porous mold 34, and the reinforcing patch 38 is inside the recess 26 to form the porous mold surface 36 of the porous mold 34. In the state of being attached to, the outer peripheral portion of the reinforcing patch 38 and the portion on the inner peripheral portion of the recess 26 on the cavity 18 side of the porous mold surface 36 of the porous mold 34 face each other. Therefore, the main base material 24 moving on the surface of the cavity portion 18 of the lower mold 14 comes into contact with the surface of the reinforcing patch 38 opposite to the porous mold surface 36, whereby the reinforcing patch 38 becomes the main base material. When the 24 is pulled toward the moving direction side and tries to move, the portion of the inner peripheral portion of the recess 26 facing the outer peripheral portion of the reinforcing patch 38 limits the movement of the reinforcing patch 38.
このように補強パッチ３８が保持され、補強パッチ３８の移動が制限されることによって、金型１２内における補強パッチ３８の位置ずれを効果的に抑制でき、成形品２２での補強パッチ３８の位置ずれを効果的に抑制できる。このため、成形品２２において剛性を高くしたい部位や機械的強度を高くしたい部位に適切に補強パッチ３８を設けることができる。 By holding the reinforcing patch 38 in this way and restricting the movement of the reinforcing patch 38, it is possible to effectively suppress the displacement of the reinforcing patch 38 in the mold 12, and the position of the reinforcing patch 38 on the molded product 22. The deviation can be effectively suppressed. Therefore, the reinforcing patch 38 can be appropriately provided in the portion of the molded product 22 where the rigidity is desired to be increased or the mechanical strength is desired to be increased.
また、上記のように、金型１２内における補強パッチ３８の位置ずれが効果的に抑制される。このため、下型１４のキャビティ部１８上での主基材２４の配置位置を特に厳格に設定しなくてもよい。これによって、成形品２２の成形工程の作業性を向上できる。 Further, as described above, the displacement of the reinforcing patch 38 in the mold 12 is effectively suppressed. Therefore, it is not necessary to strictly set the arrangement position of the main base material 24 on the cavity portion 18 of the lower mold 14. As a result, the workability of the molding process of the molded product 22 can be improved.
さらに、本実施の形態では、金型１２を型締めする前に下型１４のキャビティ部１８上に主基材２４の配置し、この状態で金型１２を型締めして主基材２４をプレスして成形する構成であった。しかしながら、本車両用樹脂部材成形装置１０は、射出成形等に用いることも可能である。 Further, in the present embodiment, the main base material 24 is arranged on the cavity 18 of the lower mold 14 before the mold 12 is molded, and the mold 12 is molded in this state to form the main base material 24. It was a structure that was pressed and molded. However, the resin member molding apparatus 10 for this vehicle can also be used for injection molding and the like.
この場合、金型１２には、型締め状態で溶融状態の主基材２４を金型１２内に流すためのスプルー、ランナー、ゲートが設定される。ここで、上述したように、金型１２内における補強パッチ３８の位置ずれが効果的に抑制される。したがって、ゲートから金型１２内に流れた主基材２４が、補強パッチ３８を押し流して移動させることを抑制できる。このため、金型１２におけるスプルー、ランナー、ゲートの位置を比較的自由に設定できる。これによって、金型１２のコストの低下を図ることができ、また、金型１２内における主基材２４の流動性を向上でき、成形品２２の品質の向上を図ることができる。 In this case, the mold 12 is set with a sprue, a runner, and a gate for flowing the main base material 24 in the molten state into the mold 12 in the mold-tightened state. Here, as described above, the displacement of the reinforcing patch 38 in the mold 12 is effectively suppressed. Therefore, it is possible to prevent the main base material 24 that has flowed from the gate into the mold 12 from being swept away and moved by the reinforcing patch 38. Therefore, the positions of the sprue, runner, and gate in the mold 12 can be set relatively freely. As a result, the cost of the mold 12 can be reduced, the fluidity of the main base material 24 in the mold 12 can be improved, and the quality of the molded product 22 can be improved.
なお、本実施の形態では、凹部２６は、下型１４に形成され、下型１４のキャビティ部１８の内面で開口された構成であった。しかしながら、凹部２６を上型１６に設け、上型１６のコア部２０の表面で凹部２６が開口する構成であってもよい。 In the present embodiment, the recess 26 is formed in the lower mold 14 and is opened on the inner surface of the cavity portion 18 of the lower mold 14. However, the recess 26 may be provided in the upper mold 16 so that the recess 26 opens on the surface of the core portion 20 of the upper mold 16.
また、本実施の形態では、図１に示されるように、複数の凹部２６が１つの吸引ポンプ３２に繋がった構成であったが、各凹部２６毎に吸引ポンプ３２を設ける構成であってもよい。 Further, in the present embodiment, as shown in FIG. 1, a plurality of recesses 26 are connected to one suction pump 32, but even in a configuration in which a suction pump 32 is provided for each recess 26. Good.
さらに、本実施の形態では、搬送装置４０によって補強パッチ３８や主基材２４を搬送する構成であったが、搬送装置４０を用いずに作業者が補強パッチ３８や主基材２４を直接搬送して金型１２内に配置する構成であってもよい。 Further, in the present embodiment, the reinforcing patch 38 and the main base material 24 are transported by the transport device 40, but the operator directly transports the reinforcing patch 38 and the main base material 24 without using the transport device 40. It may be configured to be arranged in the mold 12.
