Description

  The present invention relates to a mold rotating apparatus that rotates a mold, and more particularly, to a mold rotating apparatus that can easily reverse a mold.

  Conventionally, when the mold is inverted 180 degrees, it has been performed by the following method. First, the wires extending from the two hoists provided in the hoist crane are each attached to the end of the mold. Next, the wire is lifted by one hoist to lift one of the molds. As a result, the mold is rotated 90 degrees. Furthermore, the other hoist is lifted by lifting the wire with the other hoist. As a result, the mold is inverted 180 degrees.

  The above method requires a hoist crane, but since the hoist crane is large, it requires a large area and is fixed to the area. Further, when the mold is inverted 180 degrees by the above method, it takes time to invert the mold 180 degrees. Further, the above work has a problem that it is dangerous unless it is performed by a skilled worker.

  As a conventional technique for solving the above-described problems, a pair of support bases are connected via a reinforcing angle, and a rotary shaft is installed between the support bases. A mold reversing base having at least one hanger part in which a locking pipe for receiving a mold reversing hook is installed between the supporting arms of the mold, and a mold reversing the mold by 180 degrees by the mold reversing hook. There is a mold inversion method (see, for example, Patent Document 1).

In this mold reversal method, after lifting one end of the mold with a crane or the like, the mold reversal hook is attached to the other end of the mold. Thereafter, the mold reversing hook is hooked on the locking pipe in the mold reversing base. From that state, one end of the mold lifted by a crane or the like is lowered. Then, the mold moves downward so that one end of the mold tilts with the locking pipe as a fulcrum. As a result, the mold is inverted 180 degrees.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a mold rotation device 100 according to an embodiment of the present invention. A mold rotating device 100 according to an embodiment of the present invention rotates a mold 200, and includes a main body unit 10, a mold clamp unit 20a, a mold clamp unit 20b, and a mold clamp (not shown). And a rotation unit 30.

  A mold clamp part 20 a and a mold clamp part 20 b and a mold clamp rotating part 30 (not shown) are attached to the main body part 10. As the shape of the main body 10, for example, a U-shape as illustrated in FIG. 1 is assumed, but the shape is not limited thereto, and other shapes may be used.

  Moreover, it is preferable that the main-body part 10 shall be easily movable. In this case, the size and weight of the main body 10 may be set to a size and weight that can be lifted and moved by a small crane or lifted and moved by a forklift truck, for example. is assumed. As a result, even if a plurality of molds 200 are placed at different locations, by moving the mold rotating device 100 with a forklift truck or the like, the respective molds 200 can be rotated and inverted 180 degrees. Can do.

  The mold clamp part 20 a and the mold clamp part 20 b clamp the mold 200 from the side surface side of the mold 200. In the embodiment of the present invention, the mold clamp part is constituted by two mold clamp parts of the mold clamp part 20a and the mold clamp part 20b. However, the present invention is not limited to this, and one mold clamp is provided. You may comprise by a part. In addition, when there are three or more mold clamp portions, the mold rotating device of the present invention has three or more mold clamp portions as a result of rotating three or more mold clamp portions by a mold clamp rotating portion 30 described later. Although it is necessary to make it the structure which can rotate the metal mold | die 200 clamped by the above metal mold clamp part, the metal mold rotation apparatus of such a structure is also contained in the scope of the present invention. .

  The mold clamp part 20a includes a mold clamp main body part 21a, an insertion member 22a, and an insertion member 23a. The insertion member 22a and the insertion member 23a are attached to a predetermined position of the mold clamp main body 21a, and protrude from the predetermined surface of the mold clamp main body 21a to the outside. In the above description, two insert members in the mold clamp portion 20a are attached to the mold clamp body portion 21a. However, the present invention is not limited to this, and at least one insert member is attached to the mold clamp body portion 21a. It only has to be. The shape of the mold clamp main body 21a is assumed to be a rectangular parallelepiped shape as shown in FIG. 1, for example, but is not limited to this, and may be a disk shape or other shapes.

  The insertion member 22a and the insertion member 23a are members inserted into the hole 201a and the hole 202a provided on the side surface of the mold 200, respectively. In order to be able to move the insertion member 22a and the insertion member 23a in the direction of arrow A, for example, the insertion member 22a and the insertion member 23a can be moved in the direction of arrow A inside the mold clamp body 21a (not shown). ) A moving mechanism may be provided. This moving mechanism will be described in detail with reference to FIG.

  For example, a moving mechanism (not shown) that can move the mold clamp main body 21a in the direction of arrow A may be provided inside the main body 10. With such a mechanism, substantially the same operation as moving the insertion member 22a and the insertion member 23a in the direction of arrow A can be realized.

  The mold clamp part 20b has the same structure as the mold clamp part 20a, and the description of the mold clamp part 20a applies to the mold clamp part 20b, and therefore the description of the mold clamp part 20b is omitted.

  In order to clamp the mold 200 with the mold clamp part 20a and the mold clamp part 20b, the mold 200 is positioned between the mold clamp part 20a and the mold clamp part 20b. Then, for example, the insertion member 22a and the insertion member 23a, and the insertion member 22b and the insertion member 23b (not shown) are moved by one of the two moving mechanisms described above, so that the hole 201a provided on the side surface of the mold 200 is provided. The insertion member 22a and the insertion member 23a are inserted into the holes 202a, and the insertion member 22b and the insertion member 23b (not shown) are inserted into the holes 201b and 202b provided in the mold 200. Thereby, the mold 200 is clamped by the force from the side surface direction of the insertion member 22a and the insertion member 23a, the insertion member 22b and the insertion member 23b (not shown), and the fitting force between the insertion member and the hole.

  Note that the shape of the insertion member 22a and the insertion member 23a, and the shape of the insertion member 22b and the insertion member 23b (not shown) may be set to match the shapes of the hole 201a and the hole 202a, and the hole 201b and the hole 202b. Although it is assumed (for example, when the hole is formed in a columnar shape, the shape of the insertion member is also a columnar shape having the same size as the columnar shape), the present invention is not limited to this.

  That is, the shapes of the insertion member 22a and the insertion member 23a, and the insertion member 22b and the insertion member 23b (not shown) are the hole 201a and the hole 202a, and the hole 201b and the hole 202b. Any shape can be used as long as the mold clamping part 20a and the mold clamping part 20b can clamp the mold 200 by inserting the insertion member 23a and the insertion member 22b (not shown) and the insertion member 23b. It may be a simple shape. For example, the shape of the insertion member 22a and the insertion member 23a, and the shape of the insertion member 22b and the insertion member 23b (not shown) is a screw shape, and the shape of the hole 201a and the hole 202a, and the shape of the hole 201b and the hole 202b is a screw hole shape. It is possible.

  Further, in the above, as a method for clamping the mold 200 by the mold clamp part 20a and the mold clamp part 20b, a system for inserting an insertion member into a hole provided on the side surface of the mold 200 is shown. It is not limited to. In other words, any method may be used as long as the mold 200 can be clamped from the side surface side of the mold 200. As a system in which the mold clamp part 20a and the mold clamp part 20b clamp the mold 200, for example, a vise member having a vise structure is provided in the mold clamp body instead of the insertion member, and the vise member Thus, there is a method of clamping so as to sandwich the vicinity of both ends of the mold 200.

  The mold clamp rotating unit 30 (not shown) has a direction substantially perpendicular to the side surface of the mold 200 when the mold 200 is positioned between the mold clamp unit 20a and the mold clamp unit 20b. A predetermined axis in the mold clamp part 20a and the mold clamp part 20b (hereinafter referred to as a side-right-angled rotation axis) is a rotation axis, and the mold clamp part 20a and the mold clamp part 20b in the directions of arrows B and C. Is rotated. For example, a central axis E that passes through the center points D and D ′ of the mold clamp main body portions 21a and 21b and forms a right angle with the side surface of the mold 200 is assumed as the side surface rotation axis. Absent. The mold clamp rotating unit 30 (not shown) will be further described with reference to FIGS.

  When the mold clamp part 20a and the mold clamp part 20b are rotated in the directions of arrows B and C, respectively, the side surface right-angle rotation axes of the mold clamp part 20a and the mold clamp part 20b need to be the same. There is. This is because the mold 200 clamped by the mold clamp part 20a and the mold clamp part 20b cannot be rotated unless the side surface right-angle rotation axes of the mold clamp part 20a and the mold clamp part 20b are the same. It is. For this reason, it is preferable that the mold clamp part 20a and the mold clamp part 20b are attached to the main body part 10 so that the central axis E is a side-right angle rotation axis.

  After the mold 200 is clamped by the mold clamp part 20a and the mold clamp part 20b, the mold clamp part 20a and the mold clamp part 20b are moved to the arrows B and C by the mold clamp rotating part 30 (not shown), respectively. If it is rotated 180 degrees in the direction, the mold 200 can be inverted 180 degrees.

  FIG. 2 is a front internal view of the mold rotation device 100 according to the embodiment of the present invention. As described above, the mold rotating device 100 according to the embodiment of the present invention includes the main body unit 10, the mold clamp unit 20a, the mold clamp unit 20b, and the mold clamp rotating unit 30. Further, in the mold rotating device 100 in FIG. 2, a moving unit 24 is shown as an example of the moving mechanism of the insertion member mentioned in FIG.

  The main body 10 has been described with reference to FIG. The mold clamp part 20a includes a mold clamp main body part 21a, an insertion member 22a, an insertion member 23a, and a moving part 24. The insertion member 22a includes an insertion main member 221a and an insertion assisting member 222a connected to the insertion main member 221a. Note that the insertion member 23a is behind the insertion member 22a, and is hidden in FIG.

  The insertion main member 221a is a member that is straightly connected to the insertion portion 223a to be fitted in the hole 201a of the mold 200, and a part of the insertion main member 221a is embedded in the mold clamp main body portion 21a so as to be movable in the arrow A direction. Yes. The insertion assisting member 222a is inserted into a cylinder 241 described later and serves as a piston.

  The reason why the insertion member 22a is constituted by the insertion main member 221a and the insertion auxiliary member 222a as described above is to make the insertion member 22a sufficiently strong against the weight of the mold 200. If the strength of the insertion member 22a relative to the weight of the mold 200 can be sufficient, the insertion main member 221a may be inserted into the cylinder 241 and the insertion assisting member 222a may be omitted. Since the insertion member 23a can be described in the same manner as the insertion member 22a, the description thereof is omitted.

  The moving part 24 moves the insertion member 22a and the insertion member 23a to the hole 201a and the hole 202a of the mold 200. In FIG. 2, the moving part 24 moves the insertion member 22a and the insertion member 23a, and the insertion member 22b and the insertion member 23b in the arrow A direction. Examples of the moving member 24 that moves the insertion member 22a and the insertion member 23a, and the insertion member 22b and the insertion member 23b in the direction of arrow A include a method of moving by pressure such as a hydraulic method and a pneumatic method. However, it is not limited to this. That is, as the mode of the moving unit 24, other methods such as a method using a ball screw and a stepping motor or a method of manually moving the insertion member and fixing the insertion member with a stopper or the like may be used.

  In FIG. 2, the moving part 24 which employ | adopted the system moved with a pressure especially is shown. The moving unit 24 includes a cylinder 241 and a pressure control unit 242. As described above, the insertion assisting member 222a is inserted into the cylinder 241.

  The pressure control unit 242 controls the pressure in the cylinder 241. When the pressure in the cylinder 241 is controlled by hydraulic pressure, the pressure control unit 242 may be configured by a hydraulic control unit 243 that controls the hydraulic pressure in the cylinder 241 and an oil passage unit 244 as shown in FIG. is assumed. Further, when the pressure in the cylinder 241 is controlled by air pressure, it is assumed that the pressure control unit 242 includes an air pressure control unit that controls the air pressure in the cylinder 241 and an air passage unit. Hereinafter, a case where the pressure in the cylinder 241 is controlled by hydraulic pressure will be described.

  The hydraulic control unit 243 controls the hydraulic pressure in the cylinder 241 according to an instruction from the operation unit 40, for example. For example, when the operation unit 40 instructs to insert the insertion member 22 a into the hole 201 a of the mold 200, the hydraulic control unit 243 supplies a predetermined amount of oil to the cylinder 241 through the oil passage unit 244. Accordingly, the insertion assisting member 222a is pushed out, and the insertion main member 221a straightly connected to the insertion portion 223a is inserted into the hole 201a. On the other hand, for example, when an instruction is given to pull out the insertion member 22 a inserted into the hole 201 a of the mold 200 from the operation unit 40, the hydraulic control unit 243 sucks up the oil in the cylinder 241 through the oil passage unit 244. As a result, the insertion assisting member 222a is attracted to the inside of the cylinder 241, and the insertion main member 221a straightly connected to the insertion portion 223a is pushed out of the hole 201a of the mold 200.

  Note that when the pressure in the cylinder 241 is controlled by air pressure, the oil in the description of the hydraulic pressure can be replaced with air, and thus the description thereof is omitted.

  In addition, since the description of the moving part 24 about the above insertion member 22a can be similarly demonstrated about the insertion member 23a, description is abbreviate | omitted. Moreover, since the description in FIG. 2 can be similarly described for the mold clamp portion 20b, the description of the mold clamp portion 20b is omitted.

  As described with reference to FIG. 1, the mold clamp rotating unit 30 includes the mold clamp unit 20a and the mold clamp unit 20b with the side surface rotation shaft (for example, the central axis E described in FIG. 1) as the rotation axis. For example, the rotating power generation unit 31, the rotation shaft member 32, the rotation members 33 and 34, the mold clamp rotation mechanisms 35 and 36, and the rotation transmission member 37 are provided.

  The rotational power generating unit 31 generates rotational power. The rotational power generated by the rotational power generation unit 31 is transmitted to a rotating shaft member 32 that is a shaft connected to the rotational power generation unit 31. A rotation member 33 is attached to the rotation shaft member 32, and the rotational force transmitted to the rotation shaft member 32 is transmitted to the rotation member 33.

  On the other hand, a mold clamp rotation mechanism 35, which is a rotation mechanism with a side surface rotation axis as a rotation axis, is connected to the mold clamp portion 20b. A rotating member 34 is attached to the mold clamp rotating mechanism 35. Since the rotation transmission member 37 transmits the turning force of the rotation member 33 to the rotation member 34, the turning force in the rotation member 33 is transmitted to the rotation member 34 through the rotation transmission member 37. Since the rotation member 34 is attached to the mold clamp rotation mechanism 35 as described above, the rotational force transmitted to the rotation member 34 is transmitted to the mold clamp rotation mechanism 35. . Then, the mold clamp portion 20 b connected to the mold clamp rotation mechanism 35 is rotated by the rotational force transmitted to the mold clamp rotation mechanism 35.

  On the other hand, a mold clamp rotation mechanism 36 that is a rotation mechanism having a rotation axis about a side surface right angle rotation axis as a rotation axis is connected to the mold clamp portion 20a. When the mold 200 is clamped by the mold clamp part 20a and the mold clamp part 20b, the rotational force is transmitted from the mold clamp part 20b to the mold clamp part 20a through the mold 200. The turning force transmitted to the mold clamp part 20a is transmitted to the mold clamp rotation mechanism 36, and the mold clamp part 20a rotates.

  FIG. 3 is a side view of the mold rotation device 100 according to the embodiment of the present invention. In FIG. 3, the mold rotation device 100 according to the embodiment of the present invention uses a motor 310 as an example of the rotational power generation unit 31, and uses a sprocket 330 and a sprocket 340 as examples of the rotation members 33 and 34. As an example of the clamp rotation mechanism 35, a rotation mechanism 350 including a rotation shaft 351 and a bearing 352 is used, and a chain 370 is used as an example of the rotation transmission member 37. The operation of the mold clamp rotating unit 30 configured as described above will be described below.

  The motor 310 that receives an instruction to rotate from the operation unit 40 (not shown) starts to rotate. When the motor 310 rotates, the sprocket 330 attached in the vicinity of the end of the rotating shaft member 32 connected to the motor rotates. When the sprocket 330 rotates, the chain 370 engaged with the sprocket 330 and the sprocket 340 operates to rotate the sprocket 340 attached in the vicinity of the end of the rotating shaft 351. The rotation shaft 351 supported by the bearing 352 starts to rotate as the sprocket 340 rotates. Then, the mold clamp portion 20 b connected to the other end of the rotation shaft 351 starts to rotate with the rotation of the rotation shaft 351.

  FIG. 4 is a front internal view of a mold rotation device 400 according to another embodiment of the present invention. The mold rotation device 400 according to another embodiment of the present invention is similar to the mold rotation device 100 in that a main body 410, a mold clamp unit 420a and a mold clamp unit 420b, and a mold clamp rotation unit. 430.

  The main body 410, the mold clamp part 420a, and the mold clamp part 420b have the same structure as the main body part 10, the mold clamp part 20a, and the mold clamp part 20b. Since it has already been explained, the explanation is omitted.

  The difference between the mold rotation device 100 and the mold rotation device 400 is the structure of the mold clamp rotation unit. The mold clamp rotating part 30 transmits the rotational force directly to the mold clamp part 20b and transmits the rotational force through the mold 200 to the mold clamp part 20a. That is, it can be seen that the clutch mechanism is configured by the mold clamp part 20a, the mold clamp part 20b, and the mold 200.

  On the other hand, the mold clamp rotating part 430 is configured to transmit the rotational force directly to both the mold clamp part 20a and the mold clamp part 20b. In the mold clamp rotating part 430, the mold clamp part 20a and the mold clamp part 20b can be rotated without the mold 200. Hereinafter, the mold clamp rotating part 430 will be specifically described.

  The mold clamp rotation unit 430 includes a rotational force generation unit 431, a rotation shaft member 432, a rotation member 433a, a rotation member 433b, a rotation member 434a and a rotation member 434b, and a mold clamp rotation mechanism. 435, a mold clamp rotation mechanism 436, a rotation transmission member 437, and a rotation transmission member 438.

  The rotational power generated by the rotational power generation unit 431 is transmitted to a rotation shaft member 432 that is a shaft connected to the rotational power generation unit 431. A rotation member 433a and a rotation member 433b are attached to the rotation shaft member 432, and the rotational force transmitted to the rotation shaft member 432 is transmitted to the rotation member 433a and the rotation member 433b.

  On the other hand, a mold clamp rotation mechanism 436 which is a rotation mechanism having a side surface rotation axis as a rotation axis is connected to the mold clamp portion 420a. In addition, a mold clamp rotation mechanism 435 that is a rotation mechanism having a side surface rotation axis as a rotation axis is connected to the mold clamp portion 420b. In addition, it is assumed that the side surface rotation shaft in the mold clamp rotation mechanism 435 and the side surface rotation shaft in the mold clamp rotation mechanism 436 are the same. A rotation member 434a is attached to the mold clamp rotation mechanism 436, and a rotation member 434b is attached to the mold clamp rotation mechanism 435.

  Since the rotation transmission member 437 and the rotation transmission member 438 transmit the rotational force of the rotation member 433b and the rotation member 433a to the rotation members 434b and 434a, respectively, the rotation member 433b and the rotation member 433a. Is transmitted to the rotation member 434b and the rotation member 434a through the rotation transmission member 437 and the rotation transmission member 438, respectively.

  Since the rotation member 434b and the rotation member 434a are attached to the mold clamp rotation mechanism 435 and the mold clamp rotation mechanism 436, respectively, as described above, they are transmitted to the rotation member 434b and the rotation member 434a. The turning force thus transmitted is transmitted to the mold clamp rotation mechanism 435 and the mold clamp rotation mechanism 436. The mold clamp part 420a connected to the mold clamp rotation mechanism 436 and the mold clamp part 20b connected to the mold clamp rotation mechanism 435 are rotated by the transmitted rotational force.
