Description
本発明は、射出成形機の加熱筒保護カバーに関する。 The present invention relates to a heating cylinder protective cover for an injection molding machine.
射出成形機の加熱筒には電熱ヒータが設置されており、樹脂を溶融するために必要な熱量を供給している。この熱量の供給は、電熱ヒータと加熱筒の直接接触による熱伝導によって行われて、加熱筒は温められる。このため射出成形機には、高温になる電熱ヒータと加熱筒にオペレータが直接接触することを防止する加熱筒保護カバーが取り付けられている。 An electric heater is installed in the heating cylinder of the injection molding machine, and supplies an amount of heat necessary for melting the resin. This supply of heat is performed by heat conduction by direct contact between the electric heater and the heating cylinder, and the heating cylinder is warmed. For this reason, the injection molding machine is provided with a heating cylinder protective cover that prevents the operator from coming into direct contact with the high-temperature electric heater and the heating cylinder.
特許文献１には、保温カバーとその外側に設けられた遮熱カバーとからなる射出成形機の加熱シリンダの外側を囲む二重カバーが開示されている。この二重カバーは、熱伝達経路の距離を確保するために、加熱シリンダに保温カバーを接合する保温カバー傾斜部に一端が接合された保温カバー取付部よりも、保温カバーに遮熱カバーを接合した遮熱カバー垂直面部に形成した遮熱カバー取付部が低位置に配設されている（段落「００２７、図５参照」）。 Patent Document 1 discloses a double cover that surrounds the outside of a heating cylinder of an injection molding machine, which includes a heat insulating cover and a heat shield cover provided on the outside thereof. In order to ensure the distance of the heat transfer path, this double cover has a heat insulation cover joined to the heat insulation cover rather than a heat insulation cover attachment part in which one end is joined to the heat insulation cover inclined part that joins the heat insulation cover to the heating cylinder. The heat shield cover mounting portion formed on the vertical surface portion of the heat shield cover is disposed at a low position (see paragraph “0027, FIG. 5”).
加熱筒および加熱筒の中のスクリューの分解清掃、点検保守で加熱筒保護カバーを取り外す際に、加熱筒保護カバー取付け用ボルトを射出成形機内に落として紛失することがある。また、加熱筒保護カバーをすべて取り外さなければ、加熱筒の中のスクリューの分解清掃の作業を行うことができないことがあり、加熱筒保護カバーを取り外した場合は、電熱ヒータによって高温になっている加熱筒が露出して危険である。 When the heating cylinder protective cover is removed during disassembly cleaning, inspection and maintenance of the heating cylinder and the heating cylinder, the heating cylinder protection cover mounting bolt may be dropped in the injection molding machine and lost.

It is possible to work, reduce the exposed portion of the heating cylinder that is heated by the electric heater, and drop the heating cylinder protection cover mounting bolt into the injection molding machine when removing the heating cylinder protection cover. It is an object of the present invention to provide a heating cylinder protective cover for an injection molding machine having a structure that prevents the loss of the heating cylinder.
本発明は、加熱筒保護カバーの全てを取り外さなくても、加熱筒保護カバーの一部を取り外すことによって、加熱筒の中のスクリューの分解清掃の作業を行うことが可能である構造の加熱筒保護カバーである。また、加熱筒の中のスクリューの分解清掃、点検保守の際に取り外す加熱筒保護カバーの一部の脱着には、脱落防止ボルトと抜け止め付ボルトを活用する。以下、加熱筒の中のスクリューの分解清掃、点検保守の際に取り外さない加熱筒保護カバーを、第１の加熱筒保護カバー部材として、加熱筒の中のスクリューの分解清掃、点検保守の際に取り外す加熱筒保護カバーの一部を第２の加熱筒保護カバー部材とする。 The present invention provides a heating cylinder having a structure in which it is possible to disassemble and clean the screw in the heating cylinder by removing a part of the heating cylinder protection cover without removing all of the heating cylinder protection cover. It is a protective cover. Also, a drop-off prevention bolt and a retaining bolt are used for part of the heating cylinder protective cover that is removed during disassembly cleaning and inspection / maintenance of the screw in the heating cylinder.

A fifth surface portion 62 having a U-shaped notch 64 which is parallel and can be engaged with the head of the retaining bolt 12 of the first heating cylinder protection cover member 40. A drop-off prevention bolt 63 is inserted into the hole of the fourth surface portion.
図９は脱落防止ボルト６３を詳細に説明する図である。脱落防止ボルト６３は、首部が長い首付ボルトをカバー部材（第４の面部６１）の穴６５に挿通して抜け止めワッシャ６６でカバー部材を挟むように取付けたものである。 FIG. 9 is a diagram illustrating the drop-off prevention bolt 63 in detail. The drop-off prevention bolt 63 is attached by inserting a bolt with a long neck through the hole 65 of the cover member (fourth surface portion 61) and sandwiching the cover member with a retaining washer 66.
第２の加熱筒保護カバー部材６０の取り付け方法は、まず、第１の加熱筒保護カバー部材４０の抜け止め付ボルト１２を緩める。次に、図８の矢印方向６７に第２の加熱筒保護カバー部材６０を移動させて、脱落防止ボルト６３を第２の面部４６の穴４１を通し、第１の面部４４の溶接ナット１６に締め込む。最後にＵ字切欠き６４に通した抜け止め付ボルト１２を締め込む。以上により、第２の加熱筒保護カバー部材６０を第１の加熱筒保護カバー部材４０に固定することができる。 The method for attaching the second heating cylinder protection cover member 60 first loosens the retaining bolt 12 of the first heating cylinder protection cover member 40. Next, the second heating cylinder protective cover member 60 is moved in the direction of the arrow 67 in FIG. 8, and the drop-off prevention bolt 63 is passed through the hole 41 of the second surface portion 46 to the welding nut 16 of the first surface portion 44. Tighten. Finally, the retaining bolt 12 passed through the U-shaped notch 64 is tightened. As described above, the second heating cylinder protection cover member 60 can be fixed to the first heating cylinder protection cover member 40.
本実施形態では、第１の加熱筒保護カバー部材４０の第１の面部４４に平行で外側に位置する第２の面部４６が第２の加熱筒保護カバー部材６０の第４の面部６１と当たることによって、溶接ナット１６を有する第１の面部４４と第４の面部６１との間隔が保持されているので、首部が長い脱落防止ボルト６３の軸方向の移動に自由度がある。これによって複数箇所ある脱落防止ボルト６３を１本ずつ溶接ナット１６から抜き出したとしても、第１の加熱筒保護カバー部材４０の側面を変形させることは無い。 In the present embodiment, the second surface portion 46 that is parallel to the first surface portion 44 of the first heating tube protection cover member 40 and that is located on the outside contacts the fourth surface portion 61 of the second heating tube protection cover member 60. Thus, since the distance between the first surface portion 44 having the welding nut 16 and the fourth surface portion 61 is maintained, there is a degree of freedom in the axial movement of the drop-off preventing bolt 63 having a long neck portion. As a result, even if the plurality of drop-off prevention bolts 63 are pulled out from the welding nut 16 one by one, the side surface of the first heating tube protection cover member 40 is not deformed.
また、図１０に示すように、加熱筒保護カバーの第１の加熱筒保護カバー部材８０と第２の加熱筒保護カバー部材８１は、第２の加熱筒保護カバー部材８１を外すことにより第１の加熱筒保護カバー部材８０を外さなくても最もノズル２に近い加熱筒用電熱ヒータ３を取り外す作業スペースが確保できる構造にしても良い。なお、矢印方向８４に第２の加熱筒保護カバー部材８１を第１の加熱筒保護カバー部材３０に移動させ、第１の加熱筒保護カバー部材８０と第２の加熱筒保護カバー部材８１とを、ボルト（脱落防止ボルト２３，抜け止め付ボルト１２）によって固定する。 Further, as shown in FIG. 10, the first heating tube protection cover member 80 and the second heating tube protection cover member 81 of the heating tube protection cover are removed by removing the second heating tube protection cover member 81. It is also possible to adopt a structure in which a work space for removing the heating cylinder electric heater 3 closest to the nozzle 2 can be secured without removing the heating cylinder protection cover member 80. In addition, the 2nd heating cylinder protection cover member 81 is moved to the 1st heating cylinder protection cover member 30 in the arrow direction 84, and the 1st heating cylinder protection cover member 80 and the 2nd heating cylinder protection cover member 81 are moved. , And are fixed with bolts (fall-off prevention bolts 23, retaining bolts 12).
上述した各実施形態において、加熱筒保護カバーの材料の厚さが脱落防止ボルト２３，６３および抜け止め付ボルト１２のねじピッチに対して充分厚い場合は、溶接ナット１６を使用する代わりに、加熱筒保護カバーに雌ネジ溝を直接加工しても良い。なお、請求項に記載の「ボルト固定部」は、溶接ナット１６を用いる構成、または、加熱筒保護カバーに雌ネジ溝を直接加工した構成を意味する。 In each of the above-described embodiments, when the thickness of the material of the heating cylinder protective cover is sufficiently thick with respect to the thread pitch of the drop-off prevention bolts 23 and 63 and the retaining bolt 12, heating is performed instead of using the welding nut 16. The female thread groove may be directly processed in the cylinder protective cover. In addition, the “bolt fixing | fixed part” as described in a claim means the structure which used the welding nut 16, or the structure which processed the internal thread groove directly in the heating cylinder protective cover.
また、矩形波状の曲げの代わりに曲面または一つの平面または複数の折り曲げ平面の接続部材を用いて第１の面部と第２の面部を接続しても良い。また、第１の面と第３の面とを接続する接続部材に曲面または一つの平面または複数の折り曲げ平面を用いても良い。 Further, the first surface portion and the second surface portion may be connected using a connecting member having a curved surface, one plane, or a plurality of bending planes instead of the rectangular wave-shaped bending. Moreover, you may use a curved surface, one plane, or several bending planes for the connection member which connects a 1st surface and a 3rd surface.
