Description

本発明は、上型と下型との型締めによって所定の製品をプレス成形するための成形装置に関し、詳しくは、成形後に製品の周縁部をトリミングする成形装置に関する。   The present invention relates to a molding apparatus for press-molding a predetermined product by clamping an upper mold and a lower mold, and more particularly to a molding apparatus for trimming a peripheral portion of a product after molding.

この種の成形装置の製造工程は、成形工程と切断工程とを各々有しており、まずシート部材を成形工程で成形し、その後、成形されたシート部材を切断工程へ移動させて切断して成形品を製造していた。   The manufacturing process of this type of molding apparatus has a molding process and a cutting process. First, the sheet member is molded in the molding process, and then the molded sheet member is moved to the cutting process and cut. A molded product was manufactured.

なお、上記成形装置の製造工程は、従来より一般的であるので、あえて先行技術文献を記載しない。   In addition, since the manufacturing process of the said shaping | molding apparatus is more common than before, prior art literature is not described intentionally.

しかしながら、上記した成形装置では、成形工程後のシート部材を切断工程へ移動させて切断しているため、その移動設備および移動時間が無駄であった。また成形装置も大型となり、装置のコスト高ならびに設置スペースも大型となり無駄であった。
本発明は、このような課題を解決しようとするもので、その目的は、シート部材の成形工程から切断工程までを効率良く実施する成形装置を提供することを課題とする。 However, in the above-described forming apparatus, since the sheet member after the forming process is moved to the cutting process and cut, the moving equipment and moving time are wasted. In addition, the molding apparatus is large, and the cost of the apparatus and the installation space are large, which is useless.
An object of the present invention is to solve such a problem, and an object of the present invention is to provide a molding apparatus that efficiently performs a sheet member molding process to a cutting process.

本発明は、上記の目的を達成するためのものであって、以下のように構成されている。
請求項１に記載の発明は、シート状に押し出し成形された樹脂製のシート部材を上下型に搬送し、前記上型と前記下型との型締めによって所定の製品をプレス成形するための成形装置であって、前記上型と前記下型との型締めによる成形後に、前記上型と前記下型とをさらに型締めすることで前記シート部材を成形品とその外周の非成形品とに切断するトリミング切断刃と、前記成形後のさらなる型締めによって、前記切断後の非成形品を裁断するスクラップ切断刃と、を備えている構成である。そのため成形後にシート部材を移動させることなく、シート部材を成形品と非成形品とに切断することができる。したがって成形から切断に至る工程を効率良く実施できる。
また、前記成形後のさらなる型締めによって、前記切断後の非成形品を細分化するスクラップ切断刃を備えている構成である。そのため非成形品を裁断する粉砕機を必要としない。したがって成形装置の設置スペースを小さくすることができる。
The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is a molding for conveying a resin sheet member extruded into a sheet shape to an upper and lower mold and press-molding a predetermined product by clamping the upper mold and the lower mold. After forming the upper mold and the lower mold by clamping, the sheet member is formed into a molded product and a non-molded product on the outer periphery thereof by further clamping the upper mold and the lower mold. A trimming cutting blade for cutting, and a scrap cutting blade for cutting the non-molded product after cutting by further clamping after the molding . Therefore, the sheet member can be cut into a molded product and a non-molded product without moving the sheet member after molding. Therefore, steps from molding to cutting can be performed efficiently.
Moreover, it is the structure provided with the scrap cutting blade which subdivides the non-molded product after the said cutting by the further mold clamping after the said shaping | molding. Therefore, there is no need for a pulverizer for cutting non-molded products. Therefore, the installation space for the molding apparatus can be reduced.

請求項２に記載の発明は、請求項１に記載の成形装置であって、前記シート部材の外周を上方から吸引する吸引口を備えている構成である。そのため、吸引口の吸引により切断後の非成形品を保持することができ、吸引を解除するとその保持を開放することができる。したがって、保持を開放するタイミングを任意に設定できるため、所望するタイミングで非成形品を取り出すことができる。
Invention of Claim 2 is a shaping | molding apparatus of Claim 1, Comprising: It is the structure provided with the suction port which attracts | sucks the outer periphery of the said sheet | seat member from upper direction. Therefore, the non-molded product after cutting can be held by suction of the suction port, and when the suction is released, the holding can be released. Therefore, since the timing for releasing the holding can be arbitrarily set, the non-molded product can be taken out at a desired timing.

請求項３に記載の発明は、請求項２に記載の成形装置であって、前記吸引口と前記シート部材の非成形品となる部分を介して対向するとともに、前記非成形品となる部分を支持する押し当て部を備えている構成である。そのため、シート部材の非成形品に相当する部分を前記押し当て部によって支持することができるため、シート部材Ｓを略水平状態で型締めすることができる。したがって、成形時に、シート部材の「シワヨリ」を防止できる。
Invention of Claim 3 is a shaping | molding apparatus of Claim 2 , Comprising: While facing the said suction opening and the part used as the non-molding product of the said sheet member, the part used as the said non-molding product is It is the structure provided with the pressing part to support. For this reason, since the portion corresponding to the non-molded product of the sheet member can be supported by the pressing portion, the sheet member S can be clamped in a substantially horizontal state. Therefore, it is possible to prevent the sheet member from being “wrinkled” during molding.

以下、本発明を実施するための最良の形態を、図１〜６を用いて説明する。

FIG. 6 is a schematic configuration longitudinal sectional view showing the molding apparatus 1 of the present invention, and shows a step of discharging the sheet after the mold opening. The “upper trimming cutting blade 17 and lower trimming cutting blade 27” and “upper scrap cutting blade 18 and lower scrap cutting blade 28” described in the examples are the “trimming cutting blade” and “scrap cutting blade” of the present invention, respectively. Equivalent to.

まず図１を参照して成形装置１を説明する。この成形装置１は、上架台である上フレーム１０と下架台である下フレーム２０がフレーム支持部材３０を介して連結してある。そして上フレーム１０の下面には複数（図１に示す例では、２つ）の上型シリンダ１４、１４が配置吊設されており、そのロッド１４ａ、１４ａは上下方向に伸縮できる。また上フレーム１０の下面には複数（図１に示す例では、２つ）の支持部材１５、１５が適宜の間隔をおいてそれぞれ下方向に向けて配置吊設されている。そして、上型シリンダ１４、１４のロッド１４ａ、１４ａは、上ベース１２を上下方向に貫通している貫通孔（図示しない）を貫通しており、そのロッド１４ａ、１４ａの下端は上型１３の上面に連結されている。また支持部材１５、１５の下端は、上ベース１２の上面に連結されている。   First, the molding apparatus 1 will be described with reference to FIG. In the molding apparatus 1, an upper frame 10 that is an upper frame and a lower frame 20 that is a lower frame are connected via a frame support member 30. A plurality (two in the example shown in FIG. 1) of upper cylinders 14 and 14 are arranged and suspended on the lower surface of the upper frame 10, and the rods 14a and 14a can extend and contract in the vertical direction. A plurality of (two in the example shown in FIG. 1) support members 15 and 15 are suspended from the lower surface of the upper frame 10 with an appropriate interval therebetween. The rods 14a and 14a of the upper mold cylinders 14 and 14 pass through through holes (not shown) penetrating the upper base 12 in the vertical direction, and the lower ends of the rods 14a and 14a are Connected to the top surface. The lower ends of the support members 15 and 15 are coupled to the upper surface of the upper base 12.

また上ベース１２の下面には、上型１３を上方から嵌合する凹部１２ａが設けてあり、その凹部１２ａにより上ベース１２と上型１３とは嵌合している。そのためロッド１４ａ、１４ａを伸張して、上型１３の上面と上ベース１２の下面との間に「隙」をつくることができる。   A recess 12a for fitting the upper mold 13 from above is provided on the lower surface of the upper base 12, and the upper base 12 and the upper mold 13 are fitted by the recess 12a. Therefore, the rods 14 a and 14 a can be extended to create a “gap” between the upper surface of the upper mold 13 and the lower surface of the upper base 12.

また同様に、下フレーム２０の上面には下型シリンダ２４配置されており、そのロッド２４ａは上下方向に伸張できる。そして、そのロッド２４ａの上端は下ベース２２の下面に連結されている。   Similarly, a lower die cylinder 24 is disposed on the upper surface of the lower frame 20, and its rod 24a can extend in the vertical direction. The upper end of the rod 24 a is connected to the lower surface of the lower base 22.

また下ベース２２の上面には、下型２３が一体に設けてある。そのためロッド２４ａを伸張（加圧）すると、下ベース２２により下型２３が押し上げられるため、下フレーム２０に対して上方向に移動して型締めすることができる。   A lower mold 23 is integrally provided on the upper surface of the lower base 22. Therefore, when the rod 24a is extended (pressurized), the lower mold 23 is pushed up by the lower base 22, so that the mold can be clamped by moving upward relative to the lower frame 20.

なお、これら上型１３の下面と下型２３の上面には所望する製品の型が成形してあり、上型１３と下型２３との間にシート部材Ｓを挟み込み型締めすることで、シート部材Ｓを所望する製品の型に成形することができる。また、このようにシート部材Ｓを型締めして成形する場合、成形前に下型２３の上に置かれるシート部材Ｓのサイズは下型２３のサイズと比較してひとまわり大きいサイズである。そのため成形後のシート部材Ｓは、成形されて製品となる成形品Ｓａと、その外周部分であり成形されず製品とならない（スクラップとなる）非成形品Ｓｂとに分けられる。   A desired product mold is formed on the lower surface of the upper mold 13 and the upper surface of the lower mold 23. The sheet member S is sandwiched between the upper mold 13 and the lower mold 23, and the sheet is clamped. The member S can be formed into a desired product mold. In addition, when the sheet member S is molded by being clamped in this way, the size of the sheet member S placed on the lower mold 23 before molding is larger than the size of the lower mold 23. Therefore, the molded sheet member S is divided into a molded product Sa that is molded to become a product, and a non-molded product Sb that is an outer peripheral portion of the molded product Sa that is not molded and becomes a product (is scrap).

また上ベース１２に設けた凹部１２ａの側面には周縁状に、シート部材Ｓを切断できる上トリミング刃１７が設けてある。また上ベース１２に設けた凹部１２ａの底面には、非成形品Ｓｂを裁断できる複数（図１に示す例では、手前側と奥側の２つ）の上スクラップ切断刃１８が配置吊設されている。   Further, an upper trimming blade 17 capable of cutting the sheet member S is provided on the side surface of the recess 12a provided in the upper base 12 in a peripheral shape. A plurality of upper scrap cutting blades 18 (two on the front side and the back side in the example shown in FIG. 1) capable of cutting the non-molded product Sb are arranged and suspended on the bottom surface of the recess 12a provided on the upper base 12. ing.

また下型２３の側面には周縁状に、シート部材Ｓを切断できる下トリミング刃２７が設けてある。また下ベース２２の上面には、非成形品Ｓｂを裁断できる複数（図１に示す例では、手前側と奥側の２つ）の下スクラップ切断刃２８が配置されている。   Further, a lower trimming blade 27 capable of cutting the sheet member S is provided on the side surface of the lower mold 23 in a peripheral shape. A plurality of lower scrap cutting blades 28 (two on the front side and the back side in the example shown in FIG. 1) capable of cutting the non-molded product Sb are arranged on the upper surface of the lower base 22.

そして、これら上トリミング刃１７と下トリミング刃２７は互いに上下方向に対応する位置に設けてあるため、（すなわち上型１３と下型２３を型締めすると、上トリミング刃１７と下トリミング刃２７とがかみ合う位置に設けてあるため）シート部材Ｓを上型１３と下型２３に挟み込み成形後に、シート部材Ｓを成形品Ｓａと非成形品Ｓｂとに切断することができる。また、上スクラップ切断刃１８と下スクラップ切断刃２８も同様に対応する位置に設けてあるため、切断された非成形品Ｓｂを同時に裁断することができる。   Since the upper trimming blade 17 and the lower trimming blade 27 are provided at positions corresponding to each other in the vertical direction (that is, when the upper die 13 and the lower die 23 are clamped, the upper trimming blade 17 and the lower trimming blade 27 The sheet member S can be cut into the molded product Sa and the non-molded product Sb after the sheet member S is sandwiched between the upper mold 13 and the lower mold 23 and formed. Moreover, since the upper scrap cutting blade 18 and the lower scrap cutting blade 28 are similarly provided at corresponding positions, the cut non-molded product Sb can be simultaneously cut.

また上ベース１２の上面の両端には、複数（図１に示す例では、２つ）の吸引手段（例えば、吸引ポンプ等）１６、１６が設けてある。そして吸引手段１６、１６の吸い込み口である吸引口１６ｂ、１６ｂは、上ベース１２の下面に設けてあり、それらは吸引ダクト１６ａ、１６ａにより接続してある。   A plurality of (two in the example shown in FIG. 1) suction means (for example, suction pumps) 16 and 16 are provided at both ends of the upper surface of the upper base 12. The suction ports 16b and 16b, which are the suction ports of the suction means 16 and 16, are provided on the lower surface of the upper base 12, and are connected by suction ducts 16a and 16a.

また下ベース２２の上面の両端には、成形時に非成形品Ｓｂに相当するシート部材Ｓを支持する複数（図１に示す例では、２つ）の押し当て部材２６、２６が設けてある。この押し当て部材２６、２６は、例えば直方体状であり、その下面には下方向に向けて軸２６ａを備えている。そして軸２６ａは、弾性部材（例えば、スプリング、ゴム等）２６ｂを介して、図示しない下ベース２２の挿通孔に挿通され、その軸２６ａの先端にはナット２６ｃが螺合されている。そのため押し当て部材２６は、弾性部材２６ｂの付勢力に抗して下方向に加圧されると下方向に押し下げられ、その加圧を解除すると、弾性部材２６ｂの付勢力により加圧前の状態に戻る構成である。   Further, a plurality of (two in the example shown in FIG. 1) pressing members 26 and 26 that support the sheet member S corresponding to the non-molded product Sb at the time of molding are provided at both ends of the upper surface of the lower base 22. The pressing members 26 and 26 have, for example, a rectangular parallelepiped shape, and include a shaft 26a facing downward on the lower surface thereof. The shaft 26a is inserted into an insertion hole of the lower base 22 (not shown) via an elastic member (for example, a spring, rubber, etc.) 26b, and a nut 26c is screwed to the tip of the shaft 26a. Therefore, when the pressing member 26 is pressed downward against the biasing force of the elastic member 26b, the pressing member 26 is pressed downward. When the pressing is released, the pressing member 26 is in a state before being pressed by the biasing force of the elastic member 26b. It is the structure which returns to.

そして、これらの吸引口１６ｂ、１６ｂと押し当て部材２６、２６とは、それぞれ対向する位置に設けてある。そのため吸引手段１６、１６によって吸引しながら成形すると、シート部材Ｓの非成形品Ｓｂは、下方からは押し当て部材２６、２６により支持され上方からは吸引される。このように成形すると、成形前のシート部材Ｓが下型２３のサイズより大きくてもシート部材Ｓの外周部も略水平にして成形できるため、成形時に成形品Ｓａの周縁部に生じる「シワヨリ」を防止することができる。また成形後の型開きにおいても、吸引手段１６、１６の吸引により非成形品Ｓｂを保持し落下を防止する。   The suction ports 16b and 16b and the pressing members 26 and 26 are provided at positions facing each other. Therefore, when molding is performed while suctioning by the suction means 16, 16, the non-molded product Sb of the sheet member S is supported by the pressing members 26, 26 from below and sucked from above. In this way, even if the sheet member S before molding is larger than the size of the lower mold 23, the outer peripheral portion of the sheet member S can be formed substantially horizontally, so that “wrinkles” generated at the peripheral portion of the molded product Sa at the time of molding. Can be prevented. Further, even during mold opening after molding, the non-molded product Sb is held by suction of the suction means 16 and 16 to prevent dropping.

また上型１３および下型２３の内部には図示しない冷却配管が設けてあり、水冷式または空冷式によって成形時に冷却もおこなっている。   Further, cooling pipes (not shown) are provided inside the upper mold 13 and the lower mold 23, and cooling is performed at the time of molding by a water cooling method or an air cooling method.

つづいて、図２〜６を参照してシート部材Ｓを成形する工程を順に説明する。
まず図２に示すように、上型１３と下型２３との間にシート部材Ｓをコンベア（図示しない）により送りこみ挟み込む。そして図３に示すように、下型シリンダ２４のロッド２４ａを上方向に伸張（加圧）して下型２３と下ベース２２を押し上げシート部材Ｓを上型１３へ押し当て成形する。なお下型２３から押圧されても上型１３の上面と上ベース１２の下面との間に隙「Ｌ１」を保持できるように、上型シリンダ１４、１４のロッド１４ａ、１４ａを下方向に加圧しておく。また併せて吸引手段１６、１６からの吸引を開始する。
このようにして上型１３と下型２３とによりシート部材Ｓは成形される。またシート部材Ｓの成形品Ｓａの周縁部に「シワヨリ」が発生しない。なお、押し当て部材２６、２６の下面と下ベース２２の上面との距離を「Ｌ２」とする。 It continues and demonstrates the process of shape | molding the sheet | seat member S with reference to FIGS.
First, as shown in FIG. 2, the sheet member S is fed and sandwiched between the upper mold 13 and the lower mold 23 by a conveyor (not shown). Then, as shown in FIG. 3, the rod 24 a of the lower mold cylinder 24 is extended (pressurized) upward, the lower mold 23 and the lower base 22 are pushed up, and the sheet member S is pressed against the upper mold 13. The rods 14a and 14a of the upper mold cylinders 14 and 14 are added downward so that the gap “L1” can be maintained between the upper surface of the upper mold 13 and the lower surface of the upper base 12 even when pressed from the lower mold 23. Keep pressure. In addition, suction from the suction means 16 and 16 is started.
In this way, the sheet member S is formed by the upper mold 13 and the lower mold 23. Further, “wrinkles” do not occur at the peripheral edge of the molded product Sa of the sheet member S. The distance between the lower surfaces of the pressing members 26 and 26 and the upper surface of the lower base 22 is “L2”.

この成形中（図３）の状態では、シート部材Ｓは未だ成形品Ｓａと非成形品Ｓｂとに切断されていないため、図４に示すトリミング（切断）工程を実施する。図３で説明した成形中の状態で、上型シリンダ１４、１４のロッド１４ａ、１４ａの加圧を解除すると、下型シリンダ２５のロッド２５ａの加圧は継続しているため、下ベース２２はさらに押し上げられる。上型１３の上面と上ベース１２の下面との間には隙「Ｌ１」が生じているため、下型２３は上型１３をその隙「Ｌ１」押し上げることができる。   In this state of molding (FIG. 3), the sheet member S has not yet been cut into the molded product Sa and the non-molded product Sb, so the trimming (cutting) step shown in FIG. 4 is performed. When the pressurization of the rods 14a and 14a of the upper mold cylinders 14 and 14 is released in the state during the molding described with reference to FIG. 3, the pressurization of the rod 25a of the lower mold cylinder 25 is continued. Further pushed up. Since a gap “L1” is generated between the upper surface of the upper mold 13 and the lower surface of the upper base 12, the lower mold 23 can push up the upper mold 13 with the gap “L1”.

一方、押し当て部材２６、２６は下ベース２２により押し上げられても、上ベース１２は上フレーム１０と固定支持されているため、上ベースをさらに押し上げることはできない。そのため下ベース２２を押し上げると押し当て部材２６、２６は相対的に押し下げられる。すなわち下型２３を「Ｌ１」押し上げると、押し当て部材２６、２６は「Ｌ１」押し下げられる。そのため押し当て部材２６、２６の下面と下ベース２２の上面との距離は「Ｌ２−Ｌ１」となる。   On the other hand, even if the pressing members 26 and 26 are pushed up by the lower base 22, the upper base 12 cannot be pushed up further because the upper base 12 is fixedly supported by the upper frame 10. Therefore, when the lower base 22 is pushed up, the pressing members 26 and 26 are pushed down relatively. That is, when the lower mold 23 is pushed up by “L1”, the pressing members 26 and 26 are pushed down by “L1”. Therefore, the distance between the lower surface of the pressing members 26 and 26 and the upper surface of the lower base 22 is “L2−L1”.

このように押し当て部材２６、２６の上面は下型２３の上面より「Ｌ１」高い位置となる。そして、この押し上げ時に上トリミング刃１７と下トリミング刃２７により、シート部材Ｓは成形品Ｓａと非成形品Ｓｂとに切断される。また、この押し上げ時には、上スクラップ切断刃１８と下スクラップ切断刃２８により、切断された非成形品Ｓｂがさらに裁断され小さくなる。   In this way, the upper surfaces of the pressing members 26, 26 are higher than the upper surface of the lower mold 23 by “L1”. The sheet member S is cut into a molded product Sa and a non-molded product Sb by the upper trimming blade 17 and the lower trimming blade 27 at the time of pushing up. Further, at the time of the pushing-up, the cut non-molded product Sb is further cut and reduced by the upper scrap cutting blade 18 and the lower scrap cutting blade 28.

つぎに、上型１３と下型２３との型開きの工程について説明する。図５に示すように、下シリンダ２４のロッド２４ａ、２４ａを縮めるとシート部材Ｓの成形品Ｓａは、その側面と上トリミング刃１７、１７の内面との間に生じる摩擦力により食い込ませた格好で上トリミング刃１７、１７に保持されている。またシート部材Ｓの非成形品Ｓｂも、吸引により落下することなく吸引口１６ｂ、１６ｂに保持されている。   Next, the process of opening the mold between the upper mold 13 and the lower mold 23 will be described. As shown in FIG. 5, when the rods 24 a and 24 a of the lower cylinder 24 are contracted, the molded product Sa of the sheet member S is dressed by the frictional force generated between the side surface and the inner surfaces of the upper trimming blades 17 and 17. Are held by the upper trimming blades 17 and 17. Further, the non-molded product Sb of the sheet member S is also held in the suction ports 16b and 16b without dropping due to suction.

つづいて、成形品Ｓａと非成形品Ｓｂとを、この保持状態から取り出す（払い出す）工程について説明する。まず成形品Ｓａの取り出しについて説明する。上型１３の上面と上ベースの下面との間に隙「Ｌ１」が生じるように、上シリンダ１４、１４のロッド１４ａ、１４ａを伸張して成形前の状態に戻す。すると上トリミング刃１７、１７の摩擦力によって保持されていた成形品Ｓａは、上型１３が押し下げられることによって押し出されるため落下する。このように上型シリンダ１４、１４のロッド１４ａ、１４ａを所望するタイミングで加圧することで、所望するタイミングに成形品Ｓａ取り出すことができる。   Next, a process of taking out (dispensing) the molded product Sa and the non-molded product Sb from this holding state will be described. First, taking out of the molded product Sa will be described. The rods 14a, 14a of the upper cylinders 14, 14 are extended and returned to the state before molding so that a gap "L1" is generated between the upper surface of the upper mold 13 and the lower surface of the upper base. Then, the molded product Sa held by the frictional force of the upper trimming blades 17 and 17 falls because it is pushed out when the upper die 13 is pushed down. Thus, by pressing the rods 14a, 14a of the upper mold cylinders 14, 14 at a desired timing, the molded product Sa can be taken out at the desired timing.

つぎに非成形品Ｓｂの取り出しにについて説明する。非成形品Ｓｂは吸引手段１６、１６の吸引により吸引口１６ｂ、１６ｂに保持されているため、この吸引を解除すると吸引口１６ｂ、１６ｂから落下して取り出すことができる。このように吸引手段１６、１６の吸引を所望するタイミングで解除することで、所望するタイミングに非成形品Ｓｂ取り出すことができる。以降、連続して成形する場合は、図２の工程に戻り繰り返す。   Next, the removal of the non-molded product Sb will be described. Since the non-molded product Sb is held in the suction ports 16b and 16b by the suction of the suction means 16 and 16, when the suction is released, it can be dropped and taken out from the suction ports 16b and 16b. Thus, by canceling the suction of the suction means 16 and 16 at a desired timing, the non-molded product Sb can be taken out at a desired timing. Thereafter, when forming continuously, the process returns to the process of FIG.
