Description

  The present invention relates to a rail and guide protection member, and a guide device, a drive device, a mold clamping device, and an injection device using the rail and guide.

  Currently, in a processing apparatus such as an injection apparatus or a mold clamping apparatus used in an injection molding machine or a die casting apparatus, a guide apparatus that moves, for example, linearly moves a guide along a rail is used. Further, as such a guide device, a configuration is known in which a rail is provided with a cover in order to prevent an impediment to guidance accuracy due to foreign matter (see, for example, Patent Document 1).

  However, in the guide device described in Patent Document 1, the end surface is formed to be a flat surface, and the guide device that has come into contact with the foreign material moves so as to push out the foreign material along the moving direction. There is a risk of foreign matter being caught in between. If foreign matter is caught between the rail and the guide, the rail and the guide may be damaged.

  In addition, the rail is provided with a fixed object that restricts the movement of the guide at the end portion thereof. For this reason, even if no foreign object is caught between the rail and the guide, if the foreign object is caught between the fixed object and the guide, the movement of the guide is restricted by the foreign object, and the guide moves to the end of the rail. You may not be able to. In addition, if a foreign object is caught between the fixed object and the guide, the guide may be damaged by the foreign object.

  Therefore, in order to prevent foreign matter from being caught and foreign matter from being caught between the fixed object and the guide, a configuration is also known in which the rail is covered with bellows to prevent foreign matter from entering the rail and the guide (for example, , See Patent Document 2).

  Moreover, although it is the structure used for a railway vehicle instead of a processing apparatus, the frontal structure of a railway vehicle provided with the obstruction board which excludes the obstruction near a rail during driving | running | working is known (for example, patent document 3). reference). The baffle plate used in this frontal structure is provided with a lip portion extending in the horizontal direction at the center of the lower end of the central position of the arc-shaped frontal portion extending to the vicinity of the left and right rails, and this lip portion is used to block the obstacle. It is the structure excluded from the rail vicinity.

  The guide device 35 includes a pair of rails 61 fixed to the frame 11, guides 62 that are movably provided on the rails 61, and protective members 63 that are respectively provided at the tips of the guides 62. .

  The rail 61 extends linearly along the movable direction of the toggle link 50, that is, the direction in which the movable platen 31 moves forward and backward (forward and backward direction) with respect to the fixed platen 30. The rail 61 is formed so as to be able to guide the movement of the guide 62. The rail 61 has trapezoidal grooves 61a on both side surfaces thereof. In addition, the groove part 61a is a rolling surface of the rolling bearing of the guide 62 mentioned later, for example.

  The guide 62 is a guide (linear guide) using a pair of linear systems respectively provided on the rail 61. The guide 62 has a groove portion substantially the same as the cross-sectional shape of the rail 61, and has a rolling bearing constituted by a plurality of balls or rollers inside the groove portion.

  The guide 62 is formed to be movable along the rail 61 by a groove and a rolling bearing. As shown in FIG. 2, a pair of guides 62 are fixed to the movable platen 31 according to the width of the pair of rails 61.

  The protection member 63 is provided on the end surface of the guide 62 so as to be movable as the guide 62 moves. Specifically, as shown in FIG. 2, the protection member 63 has an end surface facing the fixed plate 30 of the leg of the movable platen 31, an end surface of the leg of the movable platen 31 facing the link housing 49, or The guide 62 is fixed to the end face of the guide 62 facing the fixed plate 30 or the end face of the guide 62 facing the link housing 49 by a fastening member B such as a bolt. In the present embodiment, the configuration in which the protection member 63 is provided on the end surface of the guide 62 facing the fixed platen 30 will be described. The protection member 63 includes an attachment portion 65 that is fixed to the guide 62 or the movable platen 31, and a protection portion 66 that covers a part of the rail 61.

  The attachment portion 65 is formed so as to be fixed to the guide 62 or the movable plate 31 by the fastening member B, for example. The attachment portion 65 is integrally fixed to the protection portion 66 by welding or a fastening member. The attachment portion 65 is formed so as to open therein so that the rail 61 can be inserted therethrough. In addition, as long as the attachment part 65 is provided in the protection part 66, it may not be fixed to the protection part 66, and may be integrally formed with the protection part 66.

  As shown in FIGS. 2 to 5, the protection part 66 is a plate material that is partially curved or bent and covers a part of the rail 61 along the upper surface and the side surface of the rail 61. Further, when the movable platen 31 moves forward toward the fixed platen 30, the protection unit 66 can move the foreign matter on the rail 61 or in the vicinity of the rail 61 in a direction away from the rail 61 with respect to the longitudinal direction of the rail 61. A side surface having a predetermined angle.

  Specifically, the member covering the outer peripheral shape of the rail 61 of the protection part 66 is arranged so that one of the apex angles is located at the approximate center of the rail 61, and its two surfaces (side surfaces) are on the rail 61. It is a triangular prismatic (mountain) plate-shaped member that is inclined with respect to the portion, and a portion through which the rail 61 is inserted opens close to the outer peripheral shape of the rail 61.

  More specifically, as shown in FIGS. 2 to 5, the protective portion 66 is formed along the outer periphery of the rail 61 so that the rail 61 can be inserted and is close to the upper surface and both side surfaces of the rail 61. A triangular prism-shaped obstruction member 68 having an opening 67 formed therein, a protrusion 69 provided in the opening 67 and adjacent to the groove 61 a of the rail 61, and an upper portion of the attachment portion 65 and the obstruction member 68. And an upper surface protection member 70 that covers the upper surface of the rail 61.

  Further, the protective portion 66 is formed so as to incline so that the obstruction member 68 and the projecting portion 69 which are side surfaces thereof spread outward from the fixed plate 30 toward the movable plate 31.

  The ends of the opening 67 and the protrusion 69 are formed along the outer periphery of the rail 61, and are close to the outer periphery of the rail 61 with a predetermined gap. Here, “adjacent with a predetermined gap” means that a foreign object is separated with a gap so as not to be caught between the rail 61 and the protection portion 66, and the guide device 35 is used. It is preferable that the gap is smaller than the possible foreign matter.

  The upper surface protection member 70 covers the upper opening of the drainage member 68 so that foreign matter can be prevented from entering the rail 61 from the opening of the mounting portion 65 and the upper portion of the triangular prism-shaped drainage member 68. Is a plate-like member formed along the outer edges of the attachment portion 65 and the obstruction member 68.

  The control unit 14 is formed to be able to control a molding operation, a mold clamping operation, and the like. The input unit 15 is formed so as to function as a human machine interface unit. The input unit 15 is, for example, a touch panel display that also serves as a display and input keys.

  In the injection molding machine 1 configured as described above, the control unit 14 drives the opening / closing mechanism 32 or the mold thickness adjusting mechanism 34 based on the command input from the input unit 15 to advance the movable platen 31 or the link housing 49. It reverses and the mold clamping of the mold clamping apparatus 13 or mold thickness adjustment is performed.

  At this time, the movable platen 31 is guided by the opening / closing mechanism 32 or the mold thickness adjusting mechanism 34 via the guide device 35 and linearly moves with respect to the fixed platen 30. When the movable platen 31 moves, when a foreign object (for example, the foreign material X in FIG. 5) enters the vicinity of the rail 61 between the guide 62 and the fixed platen 30, the protective member 63 causes the rail 61 and the guide 62 to move. Protect.

  More specifically, in the guide device 35, the guide 62 moves along the rail 61 along with the movement of the movable platen 31, and the protection member 63 also moves along the rail 61 along with the movement. .

  In the protection part 66 of the protection member 63, the obstruction member 68 and the projecting part 69 are close to each other along the outer periphery of the rail 61, and the protection part 66 moves as the guide 62 moves. For this reason, the protection member 63 can prevent foreign matter from being caught between the rail 61 and the guide 62.

  More specifically, the protection member 63 has a predetermined member so that the obstacle member 68 and the protruding portion 69 protrude outward from the fixed plate 30 toward the movable plate 31 with respect to the moving direction of the guide device 35. Has a slope. For this reason, the protection member 63 removes (bounces off) the foreign matter X abutting against the protective portion 66 due to the inclination from the rail 61 or the vicinity of the rail 61 like the foreign matter X indicated by a two-dot chain line in FIG. In other words, it can be moved away from the rail 61.

  For this reason, the protection member 63 can prevent foreign matter from being caught between the rail 61 and the guide 62, and can prevent damage and breakage of the rail 61 and the guide 62.

  Further, the protective part 66 moves the foreign object X in a direction away from the rail 61 as shown in FIG. 5 when the obstacle member 68 and the projecting part 69 have a predetermined angle with respect to the rail 61. It is possible to prevent foreign matter from being sandwiched between the guide 62 and the stationary platen 30.

  That is, the protection member 63 moves the foreign matter X located on or near the rail 61 in a direction away from the rail 61 without pushing along the movement direction of the guide device 35 by the protection unit 66. For this reason, it can prevent that a foreign material intervenes between the protection member 63 and the stationary platen 30. Further, the presence of foreign matter between the guide device 35 and the fixed plate 30 shortens the movable range of the guide device 35 (movable plate 31), and guides such as the guide 62 and the fixed plate 30 due to the foreign matter. It is possible to prevent the structural member facing 62 from being damaged.

  In addition, the protection unit 66 is configured to be close to the rail 61 with a predetermined interval but not to contact the rail 61. With this configuration, the protection unit 66 can slide with the rail 61. Absent. For this reason, it is possible to prevent an increase in the sliding resistance of the movement of the guide 62.

  Further, the protection member 63 has a simple configuration and is fixed to the guide 62 or the movable platen 31. For this reason, it can be made inexpensive without increasing the manufacturing cost.

  As described above, according to the mold clamping device 13 having the guide device 35 according to the present embodiment, the foreign matter is separated from the rail 61 by the protection portion 66, so that the rail 61, the guide 62, the fixed plate 30 and the like due to the foreign matter. It is possible to prevent the structural member facing the guide 62 from being damaged.

  The attachment portion 65A is formed so as to be fixed to the pair of guides 62 and the movable platen 31. The attachment portion 65A is formed so that the protection portion 66A can be fixed. Further, the attachment portion 65A is formed so as to open therein so that the pair of rails 61 can be inserted therethrough.

  The protection part 66A is fixed to the attachment part 65A. The protection part 66A covers at least a part of the upper surface and the outer surface of the pair of rails 61. Specifically, as shown in FIG. 6, the protection portion 66 </ b> A can be inserted through the pair of rails 61 and has a triangular shape having an opening 67 </ b> A formed close to the upper surface and the outer surface of the pair of rails 61. 68A is provided. 66 A of protection parts are provided in the said opening part 67A, and are provided with the protrusion part 69A which protrudes so that the groove part 61a provided in the outer surface of a pair of rail 61 may be adjoined.

  Further, in the protective part 66A, the obstacle member 68A and the protruding part 69A are spread outward from the fixed plate 30 toward the movable platen 31 in the same manner as the obstacle member 68 and the protruding part 69 of the first embodiment described above. It is formed so as to be inclined. In addition, in FIG. 6, the obstruction member 68A is shown in a partial cross section.

  According to the mold clamping device 13A having the guide device 35A configured as described above, it is possible to obtain the same effect as that of the mold clamping device 13 having the guide device 35 described above. Furthermore, the guide device 35 </ b> A is formed so that the protection member 63 </ b> A covers the pair of rails 61.

  For this reason, in particular, if the foreign object is higher in height than the rail 61, even if it is located between the pair of rails 61, the foreign object is effectively removed by the obstacle member 68 over the rail 61. It is possible to move to.

  The guide device 35A only needs to be provided with one protective member 63A for the pair of rails 61 and guides 62, and the number of parts can be reduced as compared with the guide device 35 according to the first embodiment described above. .

  The present invention is not limited to the embodiments described above. In the above-described example, the guide devices 35 and 35A have been described with a configuration in which the guide device itself does not have a drive portion, but the present invention is not limited to this. For example, the present invention may be applied to a device (drive device) having a drive portion such as a motor for moving the guide 62 along the rail 61 in the guide device itself (drive device) or other drive devices. All the effects described above can be obtained.

  In the example described above, the guide devices 35 and 35A have been described with respect to the configuration provided on the movable platen 31 of the mold clamping devices 13 and 13A and the configuration used for the guide portion 25 of the injection device 12, but the present invention is not limited to this. For example, it may be provided in the opening / closing mechanism 32 (mainly the link housing 49 moved by the mold thickness adjusting mechanism 34) of the mold clamping devices 13 and 13A. Even in such a case, all the above-described effects can be obtained.

  Moreover, although the protective members 63 and 63A mentioned above made the obstruction member 68 and 68A the triangular prism-shaped board | plate material, it is not limited to this. That is, the obstacle members 68 and 68 </ b> A may be configured to move the foreign matter in a direction away from the rail 61. For this reason, for example, the obstruction members 68 and 68A including the protrusions 69 and 69A may be formed by combining a plurality of plate members so as to be spread outward with respect to the movable direction. You may form combining a board | plate material. Even in such a case, all the effects described above can be obtained.

  Further, the obstacle members 68 and 68A of the protective members 63 and 63A described above are arranged so that one of the apex angles is located at the approximate center of the rail 61 or the movable platen 31, as shown in FIGS. However, it is not limited to this. That is, the side surfaces of the obstacle members 68 and 68A only need to be inclined so as to spread outward with respect to the movable direction of the guide 62, and the inclination angles of both side surfaces of the obstacle members 68 and 68A at that time are the same. Or may not be the same. Even in such a case, all the effects described above can be obtained.

  Moreover, although the protection member 63 mentioned above demonstrated the structure provided in the end surface facing the stationary platen 30 of the guide 62, it is not limited to this. That is, the protective member 63 may be provided anywhere as long as it can protect the rail 61 by moving with the movement of the guide 62, for example, the end surface of the movable platen 31 facing the fixed platen 30, or The guide 62 may be provided on an end surface facing the link housing 49. Even in such a case, all the effects described above can be obtained.

  Furthermore, although the guide devices 35 and 35A described above have been described as being used for the mold clamping devices 13 and 13A of the injection molding machine 1, the present invention is not limited to this. The guide devices 35 and 35A may be used for other processing devices, and the mold clamping devices 13 and 13A are not the injection molding machine 1 but a die casting machine, a compression molding machine (press molding machine), or transfer molding. The structure used for a machine etc. may be sufficient. Even in such a case, all the effects described above can be obtained. Moreover, you may provide the guide apparatuses 35 and 35A not only in what is called a linear guide which has a rolling bearing but in the guide which moves another rail. For example, the structure which does not have the groove part 61a as another rail may be sufficient. In this case, what is necessary is just to set it as the protection part 66 which does not have the protrusion parts 69 and 69A adjacent to the groove part 61a. Also in this case, all the above-described effects can be obtained.

In addition, various modifications can be made without departing from the scope of the present invention.
