The mold in which the casting having the casting and the lug portion is formed is separated from the casting. First, the relative positions of the hanger part of the casting and the hanger hook part are adjusted based on the position of the hanger part of the casting with respect to the mounting surface of the mold, so that the hanger hook part is hooked on the hanger part, and the mounting surface is further rotated so that the angle formed by the mounting surface of the mold and the direction of gravity becomes smaller, whereby the hanger part of the casting is hooked on the hanger hook part and the mold is dropped from the mounting surface.
Description
Technical Field
The invention relates to a demoulding method and a demoulding device applied to a casting production line.
Background
In a casting line, a mold is released after a molten metal poured into a mold is solidified and cooled. In the demolding, the cast product in which the molten metal is solidified and the casting mold in which the molding sand has been dispersed are separated. The casting is a product, and the molding sand is recovered and reused. Examples of the mold release device for releasing the mold include a rotary drum type, a vibration groove type, and a vibration drum type.
Patent document 1, which is an example of a conventional technique, discloses a technique related to mold release using a rotary drum type cooling device.
Fig. 8 is a diagram showing a rotary-drum cooling device 10 according to an example of the related art. The cooling device 10 shown in fig. 8 includes a carrying-in mechanism 11, a rotary drum 12, a carrying-out mechanism 13, a ventilation mechanism 14, a sprinkling mechanism 15, and a sand recovery mechanism 16.
The carrying-in mechanism 11 carries the mold on which the casting is formed into the rotary drum 12. The mold with the casting formed thereon enters the carrying-in mechanism 11 from the direction of the outlined arrow in fig. 8.
The rotary drum 12 rotates as indicated by the solid arrow with a rotation axis in a direction substantially coincident with the moving direction of the casting as a rotation center. In the rotating drum 12, the mold in which the casting is cast is separated from the casting, the mold becomes molding sand, and the casting and the molding sand are cooled. The casting and the molding sand move from the carrying-in mechanism 11 side to the carrying-out mechanism 13 side in the rotary drum 12, the casting is discharged to the carrying-out mechanism 13, and the molding sand is collected by the sand collecting mechanism 16.
The ventilation mechanism 14 includes a ventilation fan, and ventilates the inside of the rotary drum 12. The sprinkling mechanism 15 sprinkles the casting and the molding sand in the rotating drum 12. The sand recovery mechanism 16 is provided between the rotary drum 12 and the carry-out mechanism 13, and recovers sand in the rotary drum 12. Among the above sands, molding sand is included.
According to the cooling device 10 shown in fig. 8, the casting can be efficiently cooled by the rotation of the rotary drum 12. In addition, according to the cooling device 10, the sand at normal temperature, the dried sand at high temperature, and the core sand are mixed in the rotary drum 12, and the sand can be homogenized before being recovered by the sand recovery means 16.
As a device for performing mold release without using a rotating drum, as disclosed in patent document 2, which is one example of the prior art, there is proposed a device for performing mold release by providing a lifting lug on a cast and lifting the cast by a hook portion hooking the lifting lug.

Patent document 2: japanese patent No. 2996283
However, in the cooling device 10 shown in fig. 8, the cast may be damaged in the rotary drum 12. This is because the casting within the rotating drum 12 may contact or collide with other castings or the inner wall of the rotating drum 12. Thus, there is a problem that the damaged cast product has a hitting mark or a crack on the surface. Further, there is a problem that if a hitting mark or a crack is generated on the surface of the casting, the production efficiency is lowered.
In the cooling device 10 shown in fig. 8, the order of carrying in the casting mold formed with the casting and the order of carrying out the casting do not match. That is, the cast in the cast mold that is charged first may be discharged later than the cast in the cast mold that is charged later. Therefore, in the cooling apparatus 10, it is difficult to specify the casting order of each cast product to be discharged, and there is a problem that it is difficult to specify the production conditions of each cast product.
In addition, in the cooling apparatus 10 shown in fig. 8, there is a problem that the contact time between the casting and the sand in the rotary drum 12 is long, and the temperature of the sand increases as a whole. Further, the cooling apparatus 10 shown in fig. 8 has a problem that the amount of work for a person in the post-treatment step is large.
According to the technique disclosed in patent document 2, although the hitting mark, the crack, and the like of the casting can be prevented, the hook portion may not reach the casting due to the position of the ear portion, and the mold release may not be performed reliably.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the explanation of the following embodiments.
< embodiment one >
Fig. 1A is a diagram showing an example of the height of a mold and a casting formed on the mold, which are put into a mold release device according to the present embodiment. The mold 102a shown in fig. 1A includes an upper mold 103a and a lower mold 104a, and a casting 101A is formed between the upper mold 103a and the lower mold 104 a. The casting 101a has a casting 105a as a product and a lug portion 106 a. Fig. 1A illustrates a case where the maximum heights of the upper mold 103a and the lower mold 104a are 130mm, and the height of the mold 102a is 260 mm. Further, the upper mold 103a and the lower mold 104a abut against each other at respective portions having the largest heights, thereby enclosing the casting 101 a. The protrusion 107a and the cast portion 108a will be described later.
Fig. 1B is a view showing another example of the height of a mold and a cast formed on the mold, which are put into the mold release device of the present embodiment. The mold 102B shown in fig. 1B includes an upper mold 103B and a lower mold 104B, and a casting 101B is formed between the upper mold 103B and the lower mold 104B. The casting 101b has a casting 105b as a product and a lug portion 106 b. Fig. 1B illustrates a case where the maximum height of both the upper mold 103B and the lower mold 104B is 225mm, and the height of the mold 102B is 450 mm. Further, the upper mold 103b and the lower mold 104b abut against each other at respective portions having the largest heights, thereby enclosing the casting 101 b. As the projection 107b and the casting 108b, the following description of the projection 107a and the casting 108a is referred to.
Fig. 2 is a plan view showing a positional relationship in the mold 102a of the casting 101A shown in fig. 1A. As shown in fig. 1A and 2, the casting 101A includes a casting 105a and a lug portion 106a, and the casting 105a and the lug portion 106a are integrally formed by including portions that join them. Further, the shackle portion 31 is disposed below the shackle portion 106 a. The projection 107a formed at the portion connecting the casting 105a and the lifting lug 106a is configured to be gripped by the robot arm to the casting 101a, as will be described later. The casting portion 108a is a portion serving as a casting gate during casting.
In fig. 2, the shackle portion 106a is T-shaped, but is not limited thereto. The hanger part 106a may have an H-shape or a cross-shape. In fig. 2, two lifting lugs 106a are provided, and the casting 101a is placed on a pallet carriage and used in a subsequent step.
The positional relationship between the casting 101B and the mold 102B shown in fig. 1B is the same as the positional relationship between the casting 101a and the mold 102a, and therefore, the description thereof will be omitted with reference to fig. 2.
The lifting lug 106a of the mold 102a shown in fig. 1A is located at a height of 130mm from the mounting surface of the mold 102a, whereas the lifting lug 106B of the mold 102B shown in fig. 1B is located at a height of 225mm from the mounting surface of the mold 102B. Therefore, the position of the hooking casting 101B shown in fig. 1B is higher than the position of the hooking casting 101A shown in fig. 1A by 95mm, that is, by about 10cm, with respect to the mounting surface. Therefore, when the casting 101B shown in fig. 1B is hooked, if the hanger hook portion 31 is disposed at the same position as when the casting 101A shown in fig. 1A is hooked, the casting 101B may not hook the hanger hook portion 31. In this way, when there is a difference in the height of the hanger part of the casting in the mold, there is a possibility that the hooking of the hanger hook part fails. Therefore, in the present embodiment, the relative positions of the hanger part and the hanger hook part of the casting are adjusted by adjusting the angle of the mounting surface on which the mold is mounted.
Further, as a method for molding a mold, there are a slip flask molding and a flask molding. The height of the mold manufactured by the flask molding is determined according to the height of a flask (Japanese: jin (tm)). Thus, in the boxed mold, the heights of the molds made from the same flask are approximately the same. On the other hand, in the flask-out molding, since no flask is used for molding the mold, the heights of the molds to be manufactured are different from each other. In the above-described mold for mold release, the height of the mold is different and the height of the lug part is also different. That is, as described above, the present invention can exhibit sufficient effects when applied to the knock-out form having different heights of the mold.
In fig. 1A and 1B, the maximum height of the upper mold is the same as the maximum height of the lower mold, but the present invention is not limited thereto, and the maximum height of the upper mold may be different from the maximum height of the lower mold.
In the following description, the castings 101a and 101b are collectively referred to as a casting 101, the molds 102a and 102b are collectively referred to as a mold 102, the upper mold 103a and the upper mold 103b are collectively referred to as an upper mold 103, the lower mold 104a and the lower mold 104b are collectively referred to as a lower mold 104, the casting 105a and the casting 105b are collectively referred to as a casting 105, and the lug portions 106a and 106b are collectively referred to as lug portions 106.
Fig. 3 is a schematic view showing a casting line including the mold release device of the present embodiment. The casting line 20 shown in fig. 3 includes a mold molding device 21, a pouring device 22, a first conveying unit 23, a second conveying unit 24, and a demolding device 30.
The mold molding device 21 molds the mold 102 by molding the molding sand. Here, the casting 101 formed by the mold is formed to have a shape having a cast product and a lug portion for mold release. The casting device 22 performs casting for injecting molten metal into the mold 102 molded by the mold molding device 21.
The first conveying unit 23 conveys the mold 102, into which the molten metal is poured by the pouring device 22 to form a cast product, to the demolding device 30. The second conveying unit 24 conveys the casting 101 carried out from the demolding device 30 to a position of a next process, not shown. Here, an example of the next process is, for example, an inspection process.
The mold release device 30 separates the mold 102 conveyed by the first conveying unit 23 from the casting 101, releases the mold 102, recovers the generated molding sand, and discharges the casting 101.
Next, the mold release device 30 will be described with reference to fig. 4A and 4B. The ejector 30 has a table 32 adjacent to the forward direction of the first conveying unit 23 indicated by an outlined arrow in fig. 3. The mold 102 having the casting 101 formed thereon is placed on the table 32 by the push rod 33. Since the table 32 is supported such that the first conveying portion 23 side is rotatable about the rotation shaft 34 and the opposite side of the rotation shaft 34 is a free end, the angle of the upper surface of the table 32 can be inclined with respect to the horizontal plane. A rail 35 is disposed above the free end of the table 32 in a direction perpendicular to the paper surface, and a suspension 36 is suspended on the rail 35. A hanger hook 31 is provided at a lower end 37 of the hanger 36, and the hanger hook 31 is configured to be inserted into the mold 102.
The plurality of hangers 36 are disposed on the rail 35, and configured to sequentially advance in a direction perpendicular to the paper surface, for example, toward the inside of the paper surface after the operation of suspending the casting 101 by the hanger hooks 31 and screening out the molding sand is completed.
Next, a step of releasing the mold using the mold releasing device 30 will be described. Fig. 4A is a diagram showing a first step of mold release in the mold release device 30. In the step shown in fig. 4A, the die 102 on the first conveying unit 23 is pushed out by the push rod 33, and the die 102 is placed and set on the table 32 adjacent to the hanger hook 31 of the ejector 30. In the process shown in fig. 4A, the relative positions of the hanger-hooks 31 and the casting 101 are adjusted so that the casting 101 is hooked to the hanger-hooks 31 when the mold 102 is dropped in the subsequent process.
Fig. 5 is a detailed side view of the present embodiment showing the process shown in fig. 4A. The mold 102 shown in fig. 5 is placed on the table 32, and the angle of the table 32 rotatably supported by the rotary shaft 34 can be adjusted by extending and contracting the cylinder 38 provided on the back surface side of the table 32. The cylinder 38 is configured to extend and contract in the direction of the outlined arrow based on the position of the hanger part 106 of the casting 101, thereby tilting the mounting surface of the mold 102, and thereby allowing the hanger part 106 of the casting 101 to hook the fixed hanger part 31. The mold release device 30 acquires manufacturing data including the height of the mold 102 from the mold molding device 21, estimates the height of the lifting lug 106 of the casting 101 from the placement surface, and acquires the position of the lifting lug 106 of the casting 101.
In this way, the angle of the table 32 is adjusted to cause the casting 101 to hook the shackle hook portions 31, and the mold 102 is dropped from the table 32, so that the casting 101 can be obtained without damage. When the mold 102 is dropped from the table 32, the table 32 is rotated about the rotary shaft 34 so that the angle between the placement surface of the mold 102 and the direction of gravity is reduced, the mold 102 is dropped from the free end of the table 32 by its own weight, and the hanger hook portions 31 are hooked to the hanger portions 106 of the casting 101 when the mold 102 is dropped.
Fig. 4B is a diagram showing a second step of mold release in the mold release device 30. In the step shown in fig. 4B, the casting 101 is suspended from the hanger hooks 31, and the vibration of the vibrator 39 is applied to the projections or the casting portions of the casting 101, so that the remaining molding sand falls.
As described above, the mold release device according to the present embodiment includes the table angle adjusting unit that adjusts the angle of the table so that the lug portion hooks the lug hook portion based on the position of the lug portion with respect to the mounting surface of the mold.
As described above, according to the present embodiment, damage such as hitting marks and cracks can be prevented from occurring in the casting. Further, the hook portion can be reliably hooked, and the mold can be reliably released.
< second embodiment >
In the first embodiment, the mode in which the relative positions of the hanger hook portion and the hanger portion of the casting are adjusted by adjusting the angle of the table including the placement surface of the mold has been described, but the present invention is not limited to this, and the table may be moved up and down as described in the first embodiment.
Since the present embodiment is different from the first embodiment only in the adjustment of the relative positions of the hanger hook portion and the hanger portion of the casting, the configuration is the same as that of the first embodiment, and therefore, the description with reference to fig. 1 to 4 is incorporated.
Fig. 6 is a detailed side view of the present embodiment showing the process shown in fig. 4A. The mold 102 shown in fig. 6 is placed on the table 32, and the height of the table 32 that can be raised and lowered can be adjusted by extending and contracting the cylinder 38a provided on the back surface side of the table 32. The cylinder 38a is configured to extend and retract in the direction of the outlined arrow based on the position of the lifting lug 106 of the casting 101, thereby raising and lowering the table 32, and thereby, the lifting lug 106 of the casting 101 can be hooked to the fixed lifting lug hook 31. When the telescopic portion 38a1 indicated by oblique lines moves up and down, the table 32 moves from the position indicated by solid lines to the position indicated by broken lines, or the table 32 moves from the position indicated by broken lines to the position indicated by solid lines. The position of the lifting lug 106 of the casting 101 is obtained as in the embodiment.
In this way, the height of the table 32 is adjusted to cause the casting 101 to hook the shackle hook portions 31, and the mold 102 is dropped from the table 32, so that the casting 101 without damage is obtained. When the mold 102 falls from the table 32, the table 32 is rotated about the rotation axis 34 so that the angle formed by the placement surface of the mold 102 and the direction of gravity is reduced, and the mold 102 can fall from the free end of the table 32 by its own weight
As described above, the mold release device according to the present embodiment includes the table raising and lowering unit that raises and lowers the table based on the position of the lug portion with respect to the placement surface of the mold to adjust the height of the table, thereby causing the lug portion to hook the lug hook portion.
In the present embodiment, the table 32, which is the placement surface of the mold 102, may be raised and lowered, and the method of raising and lowering the table 32 is not limited to the above method.
In the first and second embodiments, the hanger hook portions are fixed, but the present invention is not limited to this, and the casting may be lifted by raising the hanger hook portions after the hanger hook portions are hooked to the hanger portions.
As described above in the present embodiment, the relative positions of the shackle and the table are adjusted without tilting the mounting surface of the mold and raising and lowering the mounting surface of the mold, and the mold can be reliably released without causing damage such as hitting marks and cracks in the cast.
< third embodiment >
In the first embodiment, a mode in which the relative positions of the hanger hook portion and the hanger portion of the casting are adjusted by adjusting the angle of the table has been described, and in the second embodiment, a mode in which the relative positions of the hanger hook portion and the hanger portion of the casting are adjusted by moving the table up and down has been described.
Since this embodiment is the same as the first embodiment except for the difference in the relative position adjustment between the shackle portion and the cast shackle portion as compared with the first and second embodiments, the description with reference to fig. 1 to 4 will be incorporated.
Fig. 7 is a detailed side view of the present embodiment showing the process shown in fig. 4A. A mold 102 shown in fig. 7 is placed on the table 32. The position of the shackle hook 31a may be adjusted by extension and contraction of a cylinder 38b provided to the shackle hook 31 a. The cylinder 38b is configured to extend and contract based on the position of the hanger part 106 of the casting 101 to adjust the position of the hanger hook part 31a, thereby allowing the hanger hook part 31a to hook the hanger part 106 of the casting 101. The position of the lifting lug 106 of the casting 101 is obtained as in the embodiment.
In this way, the casting 101 is hooked to the shackle hooks 31a and the mold 102 is dropped from the table 32, so that the casting 101 without damage can be obtained. When the mold 102 falls from the table 32, the table 32 is rotated about the rotation axis 34 so that the angle formed by the placement surface of the mold 102 and the direction of gravity is reduced, and the mold 102 can fall from the free end of the table 32 by its own weight
In this way, the position of the shackle hook portion 31a is adjusted so that the shackle hook portion 31a hooks the casting 101, and the mold 102 is dropped from the table 32, so that the casting 101 can be obtained without damage.
The mold release device described in the present embodiment includes the position adjusting portion for moving the hook portion of the hanger based on the position of the hook portion with respect to the mounting surface of the mold to adjust the height of the table, thereby allowing the hook portion of the hanger to hook the hook portion.
In the present embodiment, the method of adjusting the position of the shackle portion 31 is not limited to the above method as long as the position of the shackle portion 31 can be adjusted.
In the present embodiment, the hanger hook portion is movable to hook the hanger part, but the casting may be lifted by raising the hanger hook portion after the hanger hook portion is hooked to the hanger part.
As described above in the description of the present embodiment, the relative positions of the hanger hook portions and the table can be adjusted by moving the hanger hook portions without adjusting the placement surface of the mold, and damage such as hitting marks and cracks can be prevented from occurring to the casting.

a step of adjusting the height of a lifting lug hook part based on the position of the lifting lug part which is included in the manufacturing data of the casting mould and takes the carrying surface of the casting mould as a reference so as to enable the lifting lug part to be hooked by the lifting lug part; and
and dropping the casting mold from the table.
4. A demolding device that separates a mold, in which a casting having a casting and a lug portion is formed, from the casting, characterized by comprising:
a rotatable table;
a carrying mechanism that carries the casting mold onto the table;
a lifting lug hook part hooked on the lifting lug part; and
and a table angle adjusting unit that adjusts an angle of the table by extension and contraction of a cylinder provided on a back surface side of the table based on a position of the lug part on a basis of a mounting surface of the die included in the manufacturing data of the die so that the lug part is hooked by the lug hook part.
5. A demolding device that separates a casting mold, in which a casting having a casting and a lug portion is formed, from the casting, characterized by comprising:
a rotatable table;
a carrying mechanism for carrying the casting mold to the workbench;
a lifting lug hook part, which hooks the lifting lug part; and
and a table lifting unit configured to lift and lower the table based on a position of the lug part on the basis of a placement surface of the mold included in the manufacturing data of the mold, to adjust a height of the table, and to hook the lug part with the lug hook part.
6. A demolding device that separates a mold, in which a casting having a casting and a lug portion is formed, from the casting, characterized by comprising:
a rotatable table;
a carrying mechanism that carries the casting mold onto the table;
a lifting lug hook part hooked on the lifting lug part; and
a lifting lug hook position adjusting part which makes the lifting lug hook move to adjust the height of the workbench based on the position of the lifting lug part which is contained in the manufacturing data of the casting mould and takes the carrying surface of the casting mould as the reference, thereby leading the lifting lug hook to hook the lifting lug part.
7. The demolding device as claimed in any one of claims 4 to 6,
