Fig. 7 is a front view showing an actuator fixing member according to a fifth embodiment.

[0007] A power transmission unit is connected to the rotating shaft of the actuator. When the rotating shaft rotates, vibrations occur in the actuator and the power transmission unit. This tends to increase the load on the actuator fixing member that fixes the actuator. The present disclosure proposes an industrial machine that can increase the rigidity.

[0008] 1 is a schematic diagram showing an industrial machine 10 according to a first embodiment. The industrial machine 10 is an injection device that injects a molding material into a cavity of a mold, but is not limited to this. For example, the industrial machine 10 may be a mold clamping device that applies a mold clamping force to a mold.

[0009] In the following description, the front-rear direction, left-right direction, and up-down direction will be explained according to the directions of the arrows in the drawings, but these directions do not limit the actual arrangement direction.

[0010] The industrial machine 10 includes a front plate 12, a rear plate 14, a plurality of tie bars 16L, 16R, and a pusher plate 18. The front plate 12 is provided in front of the industrial machine 10. The rear plate 14 is provided in the rear of the industrial machine 10. The plurality of tie bars 16L, 16R extend in the front-to-rear direction of the industrial machine 10 and connect the front plate 12 and the rear plate 14. In FIG. 1 , two tie bars 16L are arranged vertically on the left side of the industrial machine 10. Meanwhile, two tie bars 16R are arranged vertically on the right side of the industrial machine 10. The pusher plate 18 is provided between the front plate 12 and the rear plate 14. The pusher plate 18 extends in a direction intersecting (perpendicular to) the axial direction (front-to-rear direction) of the plurality of tie bars 16L, 16R.

[0011] The pusher plate 18 is provided with sliding blocks 20L, 20R through which the tie bars 16L, 16R pass. In FIG. 1 , two sliding blocks 20L pass through each of the two tie bars 16L arranged on the left side of the industrial machine 10. Meanwhile, two sliding blocks 20R pass through each of the two tie bars 16R arranged on the right side of the industrial machine 10. The pusher plate 18 is movable in the axial direction of the tie bars 16L, 16R between the front plate 12 and the rear plate 14 via the sliding blocks 20L, 20R. The tie bars 16L, 16R are sometimes referred to as tie rods.

[0012] The pusher plate 18 rotatably supports a screw (not shown) and prevents the screw from moving in the axial direction (front-rear direction). The axial direction of the screw and the axial direction of the tie bars 16L, 16R are substantially parallel to each other (front-rear direction). Therefore, in the following description, these directions will be referred to as the "axial direction."

[0013] The industrial machine 10 further includes an actuator 22, an actuator fixing member 24, and a power transmission unit 26. The actuator 22 is a motor such as, but not limited to, a servo motor. The actuator 22 is used to inject a molding material. The actuator 22 includes an actuator main body 28 and a bracket 30 fixed to the actuator main body 28. A shaft insertion hole 30H is formed in the bracket 30. A protruding end 32E of a rotating shaft 32 provided on the actuator main body 28 is inserted into the shaft insertion hole 30H. The protruding end 32E of the rotating shaft 32 is an end that protrudes from the actuator main body 28.

[0014] The actuator fixing member 24 is attached to a base. The base is the pusher plate 18. In FIG. 1 , the actuator fixing member 24 is attached to the right side of the pusher plate 18. The actuator 22 is fixed to the actuator fixing member 24. The actuator 22 is disposed behind the actuator fixing member 24 in the axial direction. The configuration of the actuator fixing member 24 will be described in detail later.

[0015] The power transmission unit 26 converts the rotational force of the rotation shaft 32 of the actuator 22 into a linear motion force and transmits it to the pusher plate 18, thereby moving the pusher plate 18 in a direction along the axial direction of the tie bars 16L and 16R (front-to-back direction).

[0016] The power transmission unit 26 includes a drive pulley 34, a driven pulley 36, a belt 38, a ball screw 40, and a ball screw nut 42. The drive pulley 34 is non-rotatably attached to the rotary shaft 32. The driven pulley 36 is rotatably supported by the pusher plate 18 and supported so as to be non-movable in the axial direction. The driven pulley 36 is located on a portion of the pusher plate 18 on the rear plate 14 side along the axial direction. The belt 38 is stretched between the drive pulley 34 and the driven pulley 36. The ball screw 40 extends axially from the driven pulley 36 toward the rear plate 14. The ball screw 40 is coupled to the driven pulley 36 so as to be non-rotatable and non-movable in the axial direction. The ball screw nut 42 threadably engages with the ball screw 40. The ball screw nut 42 is fixed to the rear plate 14 so as to be non-rotatable and non-movable in the axial direction.

[0017] In the power transmission unit 26, when the rotary shaft 32 of the actuator 22 rotates under the control of a control device (not shown), the rotational force is transmitted to the driven pulley 36 via the drive pulley 34 and the belt 38. As a result, the driven pulley 36 and the ball screw 40 rotate together, and the rotational force is converted into a linear motion force along the axial direction. When the driven pulley 36 and the ball screw 40 rotate together, multiple components move together in the axial direction relative to the rear plate 14. The multiple components include a screw, pusher plate 18, sliding block 20R, actuator fixing member 24, actuator 22, sliding block 20L, actuator 44, and actuator fixing member 46 (not shown).

[0018] The industrial machine 10 further includes an actuator 44, an actuator fixing member 46, and a rotation transmission unit 48. The actuator 44 is a motor such as, but not limited to, a servo motor. The actuator 44 is used to rotate a screw (not shown). The actuator 44 includes an actuator body 50 and a bracket 52 fixed to the actuator body 50. The actuator body 50 may be the same as or different from the actuator body 28. A shaft insertion hole 52H is formed in the bracket 52. A protruding end of a rotation shaft (not shown) provided in the actuator body 50 is inserted into the shaft insertion hole 52H.

[0019] The actuator fixing member 46 is attached to the pusher plate 18 (base). The actuator fixing member 46 is attached to a different position on the pusher plate 18 from the actuator fixing member 24. In FIG. 1 , the actuator fixing member 46 is attached to a position on the left side of the pusher plate 18. The actuator 44 is fixed to the actuator fixing member 46. The actuator 44 is disposed behind the actuator fixing member 46 in the axial direction. The configuration of the actuator fixing member 46 is the same as, but is not limited to, the actuator fixing member 24. Details of the configuration of the actuator fixing member 24 will be described later.

[0020] The rotation transmission unit 48 includes a drive pulley (not shown), a driven pulley 54, and a belt 56. The drive pulley (not shown) is non-rotatably attached to a rotation shaft (not shown). The driven pulley 54 is rotatably supported by the pusher plate 18 and supported so as to be non-movable in the axial direction. The driven pulley 54 is located on a portion of the pusher plate 18 that is closer to the front plate 12 in the axial direction. The belt 56 is stretched between the drive pulley (not shown) and the driven pulley 54.

[0021] In the rotation transmission unit 48, when the rotation shaft of the actuator 44 rotates under the control of a control device (not shown), the rotational force is transmitted to the driven pulley 54 via a drive pulley (not shown) and a belt 56. As a result, the driven pulley 54 and a screw (not shown) rotate together.

[0022] Next, the configuration of the actuator fixing member 24 will be described. Fig. 2 is a front view showing the actuator fixing member 24 according to the first embodiment. Fig. 2 schematically shows a portion of the pusher plate 18 (base) and the actuator fixing member 24. As shown in Figs. 1 and 2, the actuator fixing member 24 has a first protrusion 60, a second protrusion 62, and a reinforcing portion 64.

[0023] The first protrusion 60 protrudes from the pusher plate 18 (base). The first protrusion 60 is formed in a plate shape, but is not limited to this. The actuator 22 is fixed to a widthwise end surface 60F ( FIG. 1 ) of the first protrusion 60. The widthwise end surface 60F is an end surface in a direction intersecting (orthogonal to) the protruding direction of the first protrusion 60, and is located behind the first protrusion 60.

[0024] The second protrusion 62 protrudes from the pusher plate 18 (base) in a direction along the protruding direction of the first protrusion 60, with a gap between it and the first protrusion 60. The second protrusion 62 is located below the first protrusion 60. The second protrusion 62 is formed in a plate shape, but is not limited to this. The actuator 22 is fixed to a widthwise end surface 62F ( FIG. 1 ) of the second protrusion 62. The widthwise end surface 62F is an end surface in a direction intersecting (orthogonal to) the protruding direction of the second protrusion 62, and is located rearward of the second protrusion 62. The widthwise end surface 62F is flush with the widthwise end surface 60F of the first protrusion 60, but is not limited to this.

[0025] The first protrusion 60 and the second protrusion 62 may be parallel to each other. That is, the protruding direction of the first protrusion 60 and the protruding direction of the second protrusion 62 may be parallel to each other.

[0026] The reinforcing portion 64 is located between the first protruding portion 60 and the second protruding portion 62, and connects the first protruding portion 60 and the second protruding portion 62. The reinforcing portion 64 includes a first partial reinforcing portion 66 and a second partial reinforcing portion 68. The first partial reinforcing portion 66 and the second partial reinforcing portion 68 are each formed in a plate shape, but are not limited to this.

[0027] 2, the longitudinal direction 66D of the first partial reinforcement portion 66 is inclined with respect to the up-down direction. The longitudinal direction 68D of the second partial reinforcement portion 68 is inclined with respect to the up-down direction. The longitudinal direction 66D of the first partial reinforcement portion 66 and the longitudinal direction 68D of the second partial reinforcement portion 68 are different from each other.

[0028] The first partial reinforcement portion 66 and the second partial reinforcement portion 68 are partially connected. That is, the first partial reinforcement portion 66 and the second partial reinforcement portion 68 are connected at a connecting portion 70. The vertical distance between the connecting portion 70 and the first protrusion 60 is equal to the vertical distance between the connecting portion 70 and the second protrusion 62. The left-right distance between the connecting portion 70 and the tip 60E1 of the first protrusion 60 is greater than the left-right distance between the connecting portion 70 and the base end 60E2 of the first protrusion 60. Similarly, the left-right distance between the connecting portion 70 and the tip 62E1 of the second protrusion 62 is greater than the left-right distance between the connecting portion 70 and the base end 62E2 of the second protrusion 62.

[0029] One end 66E1 of the first partial reinforcement portion 66 is located on the base end 60E2 side of the first protrusion 60, and the other end 66E2 of the first partial reinforcement portion 66 is located on the tip 62E1 side of the second protrusion 62. One end 68E1 of the second partial reinforcement portion 68 is located on the tip 60E1 side of the first protrusion 60, and the other end 68E2 of the second partial reinforcement portion 68 is located on the base end 62E2 side of the second protrusion 62.

[0030] The first partial reinforcement portion 66 and the second partial reinforcement portion 68 are formed in an X shape when viewed from the front. The first partial reinforcement portion 66 and the second partial reinforcement portion 68 may be formed integrally. Alternatively, the first partial reinforcement portion 66 and the second partial reinforcement portion 68 may be separate bodies. In this case, a notch or the like (not shown) is formed in one of the first partial reinforcement portion 66 and the second partial reinforcement portion 68, and the other of the first partial reinforcement portion 66 and the second partial reinforcement portion 68 is combined with the notch or the like.

[0031] FIG. 3 is a side view showing the actuator fixing member 24 according to the first embodiment. The actuator 22 and the actuator fixing member 24 are schematically shown in FIG. 3. The protruding end 32E of the rotating shaft 32 provided on the actuator 22 is located between the first protruding portion 60 and the second protruding portion 62. The distance DT between the protruding end 32E and the reinforcing portion 64 is greater than the dimension DS of the power transmission portion 26 in the axial direction of the rotating shaft 32. This makes it easier to attach and detach the belt 38 and the like to and from the rotating shaft 32.

[0032] As described above, the actuator fixing member 24 of this embodiment includes a first protrusion 60, a second protrusion 62, and a reinforcing portion 64. The first protrusion 60 protrudes from the pusher plate 18 (base portion). The second protrusion 62 protrudes from the pusher plate 18 (base portion) in a direction along the protruding direction of the first protrusion 60, with a gap between them. The reinforcing portion 64 is located between the first protrusion 60 and the second protrusion 62, and connects the first protrusion 60 and the second protrusion 62.

[0033] According to this embodiment, the reinforcing portion 64 can increase the rigidity of the actuator fixing member 24. Furthermore, the reinforcing portion 64 can suppress vibration between the first protrusion 60 and the second protrusion 62. Therefore, the generation of noise due to vibration between the first protrusion 60 and the second protrusion 62 can be suppressed.

[0034] Furthermore, in this embodiment, the reinforcement portion 64 has a first partial reinforcement portion 66 and a second partial reinforcement portion 68, and the first partial reinforcement portion 66 and the second partial reinforcement portion 68 are partially connected. This increases the strength of the reinforcement portion 64. Furthermore, compared to when the first partial reinforcement portion 66 and the second partial reinforcement portion 68 are entirely connected, a gap may be generated. Therefore, it is possible to reduce the reverberation of sound generated from the actuator 22 or the power transmission portion 26 in the space between the first protrusion 60 and the second protrusion 62. As a result, it is possible to suppress the generation of noise.

[0036] The third partial reinforcement portion 72 is formed in a columnar shape, but is not limited to this. The third partial reinforcement portion 72 and the first partial reinforcement portion 66 are arranged spaced apart from each other. The third partial reinforcement portion 72 and the second partial reinforcement portion 68 are arranged spaced apart from each other. The longitudinal direction 72D of the third partial reinforcement portion 72 is aligned with the up-down direction without being inclined with respect to the up-down direction. The third partial reinforcement portion 72 may be in contact with at least one of the first partial reinforcement portion 66 and the second partial reinforcement portion 68. Alternatively, the third partial reinforcement portion 72 may be formed integrally with at least one of the first partial reinforcement portion 66 and the second partial reinforcement portion 68.

The vertical distance between the notch 66OP of the first partial reinforcement portion 66 and the first protruding portion 60 is equal to the vertical distance between the notch 66OP of the first partial reinforcement portion 66 and the second protruding portion 62. The vertical distance between the notch 74OP of the third partial reinforcement portion 74 and the first protruding portion 60 is equal to the vertical distance between the notch 74OP of the third partial reinforcement portion 74 and the second protruding portion 62.

[0041] The second partial reinforcement portion 68 is combined with the notch 66OP of the first partial reinforcement portion 66 and the notch 74OP of the third partial reinforcement portion 74, and is disposed between the first partial reinforcement portion 66 and the third partial reinforcement portion 74.
