Description

Technical Field

[0001] The present invention relates to a casting forming device, which injects and fills a molten material into a mold cavity formed by combining a fixed mold and a movable mold, cools and solidifies the molten material in the mold cavity, opens the fixed mold and the movable mold, and removes the casting from the mold cavity. Background Art

[0002] The casting process of obtaining a casting product from a molten material such as an aluminum alloy is repeated by implementing the following steps. First, there is a process of closing the casting mold composed of a fixed mold and a movable mold to form a mold cavity. Secondly, there is an injection filling process of injecting and filling the molten material into the mold cavity, and a pressurization process of adjusting the density of the injected and filled molten material. After that, there is a cooling process of cooling and solidifying the filled molten material in the mold cavity, an opening process of opening the casting mold, a moving process of moving the casting product out of the opened mold cavity, and a preparation process of cleaning the mold cavity and applying a release agent. In order to improve the production efficiency of casting, in addition to shortening the action time of each process, there is also a strong desire to shorten the cycle by switching between processes in the shortest time.

[0003] At the same time, in order to avoid the long-term operation stop of casting and forming caused by damage or failure of casting and forming equipment such as casting molds and casting forming devices, it is necessary to quickly carry out high-precision safety monitoring. In particular, if the mold closing process is carried out in a state where all or part of the casting remains in the mold cavity (called mold residual abnormality), the casting mold will be greatly damaged and casting and forming cannot be carried out. Or, the flow of the molten material in the mold cavity is hindered (called poor melt flow), and the quality of the casting becomes unstable. Therefore, for example, by setting up an area for inspecting the castings independently of the casting forming device, and conducting safety monitoring to determine whether there is mold residual abnormality based on the inspection results of the castings, damage to the casting mold, poor melt flow, etc. can be prevented before they happen. However, in this safety monitoring, in order to determine the mold residual abnormality after the casting product removal process, it takes time to determine, the forming cycle becomes longer, and the production efficiency of casting and forming cannot be improved.

[0004] Therefore, for example, a safety monitoring scheme is proposed in which a sensor for detecting the casting is provided on the fixture part of the unloading robot operated in the unloading process as shown in Patent Document 1. Thus, since a mold residue abnormality occurs when the casting cannot be detected, it is possible to determine whether there is a mold residue abnormality at the same time as the unloading process, so the determination time is greatly shortened, and the cycle can be shortened. In addition, a safety monitoring scheme is proposed in which a photographic device is used as a sensor, and the presence or absence of a mold residue abnormality is determined based on an image of the mold cavity taken by the photographic device, as shown in Patent Document 2. Thus, it is possible to determine whether there is a mold residue abnormality at the same time as the mold opening process and the unloading process, and the determination time can be further shortened.

[0008] Patent Document 2: Japanese Patent Application Publication No. 2002-11772 Summary of the invention

[0009] Problems to be solved by the invention

[0010] For example, in casting using a molten aluminum alloy, when a high-temperature molten material of 650 to 720°C is injected and filled, the surface temperature of the mold cavity is heated to 450 to 550°C. In addition, although the holding time of the cooling process varies depending on the setting, when the cycle shortening is prioritized, the temperature of the cast product after removal is mostly 200 to 400°C. Therefore, sensors for detecting mold residual abnormalities need to be protected from high-temperature heat. Here, in Patent Document 1, an extension rod is connected to the sensor to thermally protect the sensor from the high-temperature cast product. However, even if the sensor is separated from the cast product, the sensor will still be damaged by heat because it enters the high-temperature mold cavity after the mold is opened. In addition, the fixture part of the removal robot is larger than the extension rod, so the casting mold needs to be opened significantly, and the operation time of the mold opening process and the mold closing process becomes longer, which inevitably reduces the production efficiency of the casting. Furthermore, there are limitations on the arrangement and number of sensors, and a portion without a sensor cannot be determined, so there is a concern that mold residual abnormalities may be missed.

[0011] In contrast, in Patent Document 2, since the sensor (camera photography device) is arranged at a remote position, thermal damage to the sensor can be avoided. In addition, it is conceivable that the missed detection of mold residue abnormalities can be avoided by taking large-scale images. However, since the mold cavity and the casting are in a high-temperature state, the space portion of the mold cavity after the mold is opened also becomes a high-temperature state, and the air in the space portion is heated and is in a swaying state. In addition, the release agent attached to the surface of the casting and the release agent remaining on the surface of the mold cavity are turned into a smoke state by the high-temperature heat. That is, due to the swaying of the heated air or the smoked release agent, it is difficult to clearly take an image of the mold cavity or the casting, and as a result, the accuracy of determining whether there is a mold residue abnormality is greatly reduced.

[0012] In addition, even if the casting is photographed at a position separated from the mold cavity and the presence or absence of mold residue abnormality is determined, the casting cannot be clearly identified because the fixture of the robot or the surrounding casting forming equipment overlaps with the casting, and it is easy to infer that it is difficult to determine whether there is mold residue abnormality based on the photographic image. Furthermore, the smoke from the release agent attached to the surface of the casting makes it more difficult to identify the photographic image.

[0013] Therefore, an object of the present invention is to provide a casting forming device that can quickly and accurately detect mold residue abnormalities in a casting or a part of a casting in a mold cavity, thereby improving the production efficiency of casting forming by shortening the cycle.

[0043] The following is a description of preferred embodiments for implementing the present invention using the accompanying drawings. In addition, the following embodiments do not limit the invention according to the claims. In addition, all combinations of the features described in the embodiments are not necessarily necessary for the solution means of the invention according to the claims. In addition, in this embodiment, there are cases where the scale or size of each structural element is exaggerated, or a part of the structural element is omitted.

[0044] (First Implementation Method)

[0045] First, use Figure 1 A casting and forming apparatus according to a first embodiment of the present invention will be described. Figure 1 The casting device 100 shown includes an injection unit 10, a mold clamping unit 20, a casting product unloading unit 30, an image capturing and determining unit 40, and a mold release agent applying unit 90. The injection unit 10 and the mold clamping unit 20 are arranged in the horizontal direction (horizontal casting device).

[0046] The injection unit 10 is equipped with: a cylindrical injection sleeve 11 arranged along the horizontal direction, a plunger piece 12 sliding in the front-back direction in the injection sleeve 11, and a pouring port 16 for supplying a molten material such as an aluminum alloy into the injection sleeve 11. The plunger piece 12 and the injection drive unit 14 are connected by a plunger rod 13, and the injection control unit 15 operates the injection drive unit 14 to control the sliding of the plunger piece 12 in the front-back direction. A cooling mechanism not shown in the figure including a flow path for a cooling medium such as cooling water to flow is provided in the injection sleeve 11 and the plunger piece 12 as needed. In addition, in order to prevent wear damage to the plunger piece 2, stabilize the sliding state, and suppress the adhesion of molten residue, it is preferred that a lubricant is applied to the sliding surface of the injection sleeve 11 and the plunger piece 12. In addition, a vacuum suction mechanism not shown in the figure can also be provided in the injection sleeve 11 to form a form in which the vacuum suction of the injection sleeve 11 and the injection filling of the molten material are combined.

[0047] The mold clamping unit 20 is equipped with a fixed platen 21 supporting a fixed mold 25, a movable platen 22 supporting a movable mold 26, and a mold clamping platen 23 supporting a mold clamping driving unit 27 in the horizontal direction. The fixed platen 21 and the mold clamping platen 23 are connected by a plurality of tie rods 24 penetrating the movable platen 22. The mold clamping control unit 28 operates the mold clamping driving unit 27, and controls the sliding of the movable platen 22 in the mold opening and closing direction using the tie rods 24 as guides. The mold clamping driving unit 27 is, for example, a mold clamping mechanism equipped with a hydraulic cylinder driven by a hydraulic pressure, and is in a form in which the rod of the hydraulic cylinder is connected to the movable platen 22. Here, regarding the sliding of the movable platen 22, the sliding close to the fixed platen 21 is defined as a mold clamping action, and the sliding away from the fixed platen 21 is defined as a mold opening action. Through the mold clamping action of the movable platen 22, the fixed mold 25 and the movable mold 26 are clamped to form a space (referred to as a mold cavity CV) when the mold is closed. Alternatively, the operation until the fixed mold 25 and the movable mold 26 are clamped together may be defined as a mold closing operation, and the operation from the clamping of the molds to the formation of the mold cavity CV may be defined as a mold clamping operation.

[0048] The end of the injection sleeve 11 (the side opposite to the pouring gate 16) passes through the fixed plate 21 and the fixed mold 25, and is connected to the entrance (called runner or gate) of the mold cavity CV. Here, regarding the sliding of the plunger piece 12, the direction approaching the gate is defined as the front F, the sliding in the direction of the front F is defined as the forward movement, the direction away from the gate is defined as the rear R, and the sliding in the direction of the rear R is defined as the backward movement. The plunger piece 12 moves backward to the rear R side of the pouring gate 16, and a specified amount of melt is supplied from the pouring gate 16 to the injection sleeve 11 by a melt supply mechanism not shown in the figure. Through the forward movement of the plunger piece 12, the supplied melt in the injection sleeve 11 is injected and filled into the mold cavity CV through the pouring gate. The injection filling of the melt is called an injection action. In addition, a vacuum suction mechanism not shown in the figure can be set in the fixed mold 25 or the movable mold 26, and the vacuum suction and injection action in the mold cavity CV can be combined. In addition, a vacuum suction mechanism may be provided in the injection sleeve 11 so that vacuum suction is performed in the mold cavity CV by vacuum suction from the injection sleeve 11 .

[0049] The fixed mold 25 and the movable mold 26 are heated to high temperatures due to the injection filling of the molten material. For example, when a molten material such as an aluminum alloy maintained at a melting temperature of 650 to 720°C is used, the surface temperature of the mold cavity CV during the mold opening operation becomes a high temperature state of 450 to 550°C. In addition, the casting MP just after being removed from the mold cavity CV is in a high temperature state of 200 to 400°C. Therefore, in order to stabilize the surface temperature of the mold cavity CV and the temperature of the casting MP and shorten the casting cycle, it is preferred that a cooling mechanism including a cooling circuit not shown in the figure is provided in the fixed mold 25 and the movable mold 26.

[0050] The casting unloading section 30 is supported on the upper part of the fixed plate 21, and is equipped with a product arm 21 that moves up and down in the vertical direction, and a product fixture 32 supported at the end of the product arm 31. Simultaneously with the mold opening action, or after the mold opening action, the unloading control section 34 operates the unloading drive section 33 to move the product arm 31, so that the product fixture 32 enters the space 29 surrounded by the fixed mold 25 and the movable mold 26 (referred to as a descending action or an entering action). The casting MP is pushed out from the mold cavity surface CS of the movable mold 26 by means of an ejection mechanism (not shown in the figure) assembled on the movable mold 26 (referred to as an ejection action). In addition, at Figure 1 In the embodiment, during the mold opening operation, the casting MP remains in the movable mold 26, and the casting MP is pushed out from the movable mold 26. However, the present invention is not limited thereto. For example, during the mold opening operation, the casting MP remains in the fixed mold 25, and the casting MP is pushed out from the fixed mold 25. In this case, an ejection mechanism is provided in the fixed mold 25, and the product fixture 32 faces the fixed mold 25 side. In addition, when the ejection operation of ejecting the casting MP from the fixed mold 25 is performed, it is preferred that a reversing mechanism is provided in the product fixture 32, and the product fixture 32 is reversed while holding the casting MP, so as to form a Figure 1 In this embodiment, the ejection of the cast product MP from the movable mold 26 will be described.

[0051] After the push-out action, or simultaneously with the push-out action, the carry-out control unit 34 operates the product fixture 32, and uses the product fixture 32 to grasp the position of the casting MP called the biscuit, and separates the casting MP from the mold cavity CV (called demolding action). The position of this demolding action is defined as the demolding position. The biscuit grasped by the product fixture 32 is a position separated from the product surface of the casting MP, and does not affect the image photography of the casting MP to be described later. After that, the carry-out control unit 34 operates the product arm 31 to carry the casting MP out of the space portion 29 surrounded by the fixed mold 25 and the movable mold 26 (called a rising action or a carry-out action). The position after the carry-out is defined as the carry-out position. Figure 1 Indicates the state of the unloading position. After that, the casting MP is transported to a predetermined position, and subsequent processes such as burr treatment are continued on the casting MP. Therefore, the casting unloading section 30 is equipped with a transport mechanism for transporting the casting MP to the subsequent process, a mechanism for adjusting the position of the descending action or ascending action and the demoulding action, etc.

[0052] The image photography determination unit 40 is equipped with: an image photography unit 41 for photographing an image of the casting MP at a specified photography position; an image data collection unit 42 for collecting image data photographed by the image photography unit 41; a mold residue determination unit 43 for determining whether there is a mold residue abnormality in which all or part of the casting MP remains in the mold cavity CV; and a determination display unit 44 as a notification unit for displaying the determination result of the mold residue determination unit 43.

[0053] Here, if Figure 1 As shown, the prescribed photographing position is the carrying-out position where the product holder 32 of the casting carrying-out part 30 grasps the material handle of the casting MP at a position separated from the product surface and completes the carrying-out action. Due to the high-temperature mold cavity CV or the casting MP, the space 29 surrounded by the fixed mold 25 and the movable mold 26 is in a state that is not suitable for image photography of the casting MP together with the swaying of the heated air and the smoke from the mold release agent. The carrying-out position is set to a position that can avoid this inappropriate state at the shortest distance. As a result, clear image photography of the casting MP can be performed, and the accuracy of determining whether there is an abnormal mold residue can be improved. In addition, since it is the shortest distance, the determination time of whether there is an abnormal mold residue can be shortened, which is very helpful in shortening the casting cycle. In addition, by taking pictures while keeping the casting MP grasped by the product holder 32, the shooting time can be shortened, and then the casting MP can be immediately transported to the prescribed position after shooting, eliminating useless actions. The cycle is reliably shortened.

[0054] The image photographing section 41 is arranged at a position separated from the fixed mold 25 and the movable mold 26 in a high temperature state and capable of photographing the image of the casting MP at the unloading position. Thus, thermal damage can be reliably avoided. In addition, in the case where smoke is generated from the release agent attached to the casting MP and hinders the image photography, air is sprayed toward the casting MP from the first blower mechanism 36 provided in the casting unloading section 30, and after the smoke is blown away, the image photography is performed. By doing so, clear image photography of the casting MP can be performed, and the accuracy of determining whether there is a mold residue abnormality can be improved. In addition, it is also possible to spray air from the second blower mechanism 92 provided in the release agent coating section 90 waiting at a predetermined position to the unloading position, more preferably, to the casting MP at the unloading position to blow it away.

[0055] In addition, it is preferable that the image capturing unit 41 captures the product surface of the casting MP from the front side so that the product clamp 32 holding the material handle is on the back side. Since the material handle is located at a position separated from the product surface of the casting MP, it has no influence on the image capturing of the product surface of the casting MP. However, the product arm 31 of the casting unloading unit 30, the support and other structures, or the peripheral equipment related to the casting forming device 100, etc., may be reflected in a manner overlapping the back side of the casting MP. As a result, the product surface of the casting MP cannot be clearly captured, and there is a risk that the accuracy of determining whether there is a mold residue abnormality is reduced. Therefore, the photography auxiliary plate 35 is provided in the casting unloading unit 30 so as to overlap with the back side of the casting MP, and the image is captured from the front side of the casting MP in a state where the photography auxiliary plate 35 overlaps with the back side of the casting MP. As a result, the back side structures overlapping with the product surface of the casting MP are blocked from sight, and the product surface of the casting MP can be clearly captured, which can improve the accuracy of determining whether there is a mold residue abnormality. Details Figure 2 Provide explanation.

[0056] In addition, Figure 1 In the figure, there is only one image photographing unit 41, but it is not limited to this. For example, multiple image photographing units 41 may be used to photograph the image of the casting MP, and the image data of each image may be edited into one image data by image synthesis or other processing means to determine whether there is a mold residual abnormality. Alternatively, each image data may be determined separately. In addition, since it is assumed that there are multiple mold residual abnormalities, it is also preferable to comprehensively evaluate the determination results when each image data is determined separately. When multiple image photographing units 41 are used, there are no restrictions on the configuration and photography direction of the image photographing units 41.

[0057] Figure 2 An example of image data of the cast product MP imaged by the image capturing unit 41 is shown. Figure 2 (a) shows the image data without mold residue abnormality. Figure 2(b) shows image data in the case of mold residue abnormality. In either case, the photography auxiliary plate 35 is arranged to overlap the inner side of the product surface SM of the casting MP and the material handle BK is grasped by the product clamp 32. The material handle BK and the product surface SM are between the gate YG. In addition, the mold is designed to be provided with a plurality of venting grooves GP on the periphery of the product surface SM, and the venting grooves GP have both the function of discharging the gas in the mold cavity CV and the function of adjusting the filling amount error of the molten material. In addition, for example, when the casting MP can be clearly imaged even without the photography auxiliary plate 35 by using a plurality of image data, and the presence or absence of mold residue abnormality can be clearly determined, the photography auxiliary plate 35 can be omitted.

[0058] Here, if Figure 2 As shown in (a), the image data without mold residue abnormality is used as the reference image data and recorded in advance in the mold residue determination unit 43. The mold residue determination unit 43 compares the image data collected in the image data collection unit 42 with the reference image data to determine whether there is a mold residue abnormality. Figure 2 As shown in (b), when image data showing a portion of the vent groove GP is collected, as shown by the dotted line, it is determined that there is a risk that the defective vent groove GR remains in the mold cavity CV, and the mold remainder determination unit 43 determines that there is a mold remainder abnormality.

[0059] The image photographing unit 41 can use a 3D camera, etc., which can capture image data with a pixel number that can clearly identify the shape and contour of the casting MP. Alternatively, an infrared thermal camera that can photograph the temperature distribution as image data, or a colorimeter that converts the temperature difference into color difference as image data can also be used. In either case, a known image photographing device can be used. In addition, the mold residue determination unit 43 uses a known method of image analysis such as image processing and binary image or image recognition for each image data, compares the image data collected by the image data collection unit 42 with the reference image data recorded in the mold residue determination unit 43, and determines whether there is a mold residue abnormality.

[0060] Here, by using a photography auxiliary plate 35 of a different color tone from the casting MP, the image data of the casting MP becomes clearer, and the accuracy of determining whether there is a mold residue abnormality can be further improved. In addition, for example, when the image capturing unit 41 uses an infrared thermal camera, the temperature difference between the casting MP and the photography auxiliary plate 35 becomes significant, and the thermal image data of the casting MP can be made clear. In addition, the color tone of the photography auxiliary plate 35 can be any color as long as it is a color that makes the casting MP stand out. For example, JIS Z8721-1993 "3. Method of expressing three attributes" Figure 1Any one of RP (purple red), R (red), YR (orange red), Y (yellow), GY (yellow-green), and G (green) in the color wheel, particularly preferably YR (orange red) and Y (yellow).

[0061] The determination result of the mold residue determination unit 43 is as follows: Figure 3 As shown in (a), the judgment display unit 44 displays the image data on the screen. When the mold residue judgment unit 43 judges that there is no mold residue abnormality, the judgment display unit 44 displays the screen as normal. Figure 1 As shown, the release agent coating unit 90 waiting at a predetermined position enters the space 29 surrounded by the fixed mold 25 and the movable mold 26, and sprays air from the second air blowing mechanism 92 to clean the mold cavity CV, and sprays the release agent from the release agent spray nozzle 91 to the surface of the mold cavity CV, and the release agent coating preparation process begins, and the casting operation continues. In this way, by taking an image of the casting MP at the unloading position and determining whether there is an abnormal mold residue, the determination time can be minimized, and the casting production efficiency can be maintained at a high state.

[0062] When the mold residue determination 43 determines that there is a mold residue abnormality, such as Figure 3 As shown in (a), the display unit 44 is judged to be abnormal. At the same time, the image data of the casting MP or the image data of the mold cavity CV of the movable mold 26 (or the fixed mold 25) for demolding the casting MP is displayed on the screen. The image data displayed on the screen is displayed so that the position of the mold residual abnormality can be identified. Figure 3 (a), the defective venting groove GR is displayed as a mold residue abnormality in a black background. In addition, the operation of the casting is stopped, and an alarm is sounded to draw the attention of the forming operator. The forming operator can reliably identify the location where the mold residue abnormality occurs by watching the display screen of the judgment display unit 44, and can quickly remove the mold residue venting groove GR from the mold cavity CV. As a result, the time for stopping the operation of the casting can be minimized, and the production efficiency of the casting can be restored to a high state. In addition, the use of the judgment display unit 44 to visually display the normal and abnormal mold residues is described here, but it is not limited to this. For example, the judgment result can also be notified in the form of an alarm sound or sending an external terminal (for example, a signal for displaying on the screen of the external terminal or vibrating the external terminal so that the operator can perceive it).

[0063] Next, use Figure 3 (b) The entry and exit operations of the cast product unloading section 30 and the release agent applying section 90 will be described. Figure 3 (b) shows the state where the casting MP is released from the movable mold 26. Figure 1As shown in FIG. 1 , when the casting product carrying-out unit 30 is supported on the upper part of the fixed plate 21, the entering action and the carrying-out action of the casting product carrying-out unit 30 become Figure 3 (b) The direction of arrow A shown in FIG. The entry and removal movements of the release agent coating unit 90 are in the direction of arrow B or arrow C so as not to interfere with the various movements of the casting removal unit 30. In addition, when the various movements of the casting removal unit 30 are in the direction of arrow B, the various movements of the release agent coating unit 90 are in the direction of arrow C or arrow A. Similarly, when the various movements of the casting removal unit 30 are in the direction of arrow C, the various movements of the release agent coating unit 90 are in the direction of arrow B or arrow A. In this way, the directions of the various movements of the casting removal unit 30 and the release agent coating unit 90 do not interfere with each other, thereby eliminating the waste of waiting time for the movement, and can make the various movements in unison according to the conditions, which is very helpful to shorten the casting cycle and improve the production efficiency of casting.

[0064] In addition, when the entry and removal actions of the casting unloading unit 30 and the release agent coating unit 90 are arranged in the same direction, the entry and removal actions of the casting unloading unit 30 are performed first, and the entry and removal actions of the release agent coating unit 90 are performed secondly, with a time difference. Thus, interference between the casting unloading unit 30 and the release agent coating unit 90 can be avoided. However, in this case, the casting cycle is longer by an amount equivalent to the time difference. Therefore, in the case where shortening the casting cycle is preferred, it is preferred that the entry and removal actions of the casting unloading unit 30 and the release agent coating unit 90 are arranged non-overlappingly.

[0065] in addition, Figure 1 The injection unit 10 of the casting forming device 100 shown in the figure is a form in which the molten material is supplied from the pouring port 16 to the injection sleeve 11, but it is not limited to this. For example, it can also be a form in which a molten storage furnace not shown in the figure storing the molten material is connected to the injection sleeve 11 by a molten material supply mechanism not shown in the figure, and the molten material is directly supplied from the molten storage furnace to the injection sleeve 11 via the molten material supply mechanism. In addition, the mold clamping unit 20 is a form in which a hydraulic cylinder driven by a hydraulic pressure is used to make the movable plate 22 open and close the mold, but, for example, it can also be a form in which a toggle type mold clamping mechanism is provided instead of a hydraulic cylinder, and it can also be a form in which a power transmission mechanism such as an electric motor and a ball screw is combined instead of a hydraulic drive. In addition, it can also be a form in which the mold clamping drive unit 27 is arranged on the tie rod 24, and the tie rod 24 and the movable plate 22 are connected by a connecting mechanism such as a split nut, so that the movable plate 22 can open and close the mold. In this case, the mold clamping plate 23 can also be omitted.

[0066] (Second Implementation Method)

[0067] Next, use Figure 4 A casting and forming apparatus according to a second embodiment of the present invention will be described. Figure 4 The casting forming device 200 shown in FIG. Figure 1 The casting forming device 100 shown is similarly equipped with an injection unit 10, a mold clamping unit 20, a casting product carrying unit 30, an image photographing and determining unit 40, and a mold release agent applying unit 90, and is a form (horizontal casting forming device) in which the injection unit 10 and the mold clamping unit 20 are arranged in the horizontal direction. The second embodiment is different from the first embodiment in the position of capturing the image of the casting product MP, so the description of the parts repeated with the first embodiment is omitted.

[0068] First, a molten material is injected and filled from the injection unit 10 into the mold cavity CV formed by the clamping action of the fixed mold 25 and the movable mold 26, and the molten material is cooled and solidified in the mold cavity CV to form the casting MP. After that, after the opening action of the fixed mold 25 and the movable mold 26, or simultaneously with the opening action, the product fixture 32 enters the space 29 surrounded by the fixed mold 25 and the movable mold 26. After the ejection action of the casting MP, or simultaneously with the ejection action, a demolding action is performed by grasping the material handle BK separated from the product surface SM of the casting MP using the product fixture 32. The position of this demolding action is defined as the demolding position. In addition, at Figure 4 In the embodiment, the ejection operation of the cast product MP is performed from the movable mold 26 , but, for example, the ejection operation of the cast product MP may be performed from the fixed mold 25 . In this case, the product jig 32 is arranged toward the fixed mold 25 .

[0069] The image photographing section 41 of the image photographing determination section 40 is disposed at a position separated from the space section 29 surrounded by the fixed mold 25 and the movable mold 26 that have performed the mold opening action, and uses the demolding position as the shooting position to perform image photography of the casting MP. Since the image photographing section 41 is away from the high temperature state, thermal damage can be reliably avoided. In addition, when the casting MP is pushed out from the fixed mold 25, the image photographing section 41 is disposed above the fixed plate 21. Alternatively, a reversing mechanism may be provided in the product fixture 32, so that after the demolding action, the casting MP is kept gripped and the product fixture 32 is reversed. Figure 1 In the state shown, the image of the cast product MP is photographed at the demolding position.

[0070] At the same time as the image of the casting MP is photographed, or before the image is photographed, air is sprayed from the second air blowing mechanism 92 provided in the release agent coating unit 90 to the space 29 surrounded by the fixed mold 25 and the movable mold 26, more preferably to the casting MP at the demolding position. As a result, the swaying of the air heated to a high temperature by the fixed mold 25 and the movable mold 26 or the casting MP in a high temperature state and the smoke generated from the attached release agent can be blown away. As a result, a clear image of the casting MP can be photographed even at the demolding position, and the accuracy of determining whether there is an abnormal mold residue can be improved. In addition, by photographing the casting MP at the demolding position and determining whether there is an abnormal mold residue, the time required for determination can be greatly shortened, and the production efficiency of casting molding can be greatly improved by shortening the cycle.

[0071] After the image of the casting MP is photographed at the demolding position, the image data collected in the image data collection unit 42 is compared with the reference image data recorded in the mold residue determination unit 43, and the mold residue determination unit 43 determines whether there is a mold residue abnormality, and the determination display unit 44 displays the determination result on the screen using the image data. When it is determined that there is no mold residue abnormality, after the casting MP is carried out by the casting unloading unit 30, or at the same time as the carrying out action, the mold release agent coating unit 90 performs an entry action, enters the cleaning of the mold cavity CV and the preparation process of the mold release agent coating, and the casting operation continues. When it is determined that there is a mold residue abnormality, after the casting unloading unit 30 carries out the casting MP, the casting operation is stopped, the molding operator handles the mold residue abnormality, and the casting operation is restarted.

[0072] In addition, Figure 4 In the embodiment, there is only one image photographing unit 41, but, as in the first embodiment, a plurality of image photographing units 41 may be used to determine whether there is an abnormal mold residue. In addition, with respect to other aspects, reference may be made to the first embodiment, and the same means may be adopted. For example, in the case where the casting MP can be clearly imaged and whether there is an abnormal mold residue can be clearly determined, the photography auxiliary plate 35 may be omitted. In addition, although it is preferred that the entry and removal actions of the casting unloading unit 30 and the release agent coating unit 90 are arranged at non-overlapping positions, for example, in the case where they are arranged at the same position, a first air blowing mechanism 36 may be provided near the product fixture 32, and air may be sprayed toward the casting MP from the first air blowing mechanism 36.

[0073] (Third Implementation Method)

[0074] Next, use Figure 5 A casting and forming apparatus according to a third embodiment of the present invention will be described. Figure 5 The casting device 300 shown includes an injection unit 50, a mold clamping unit 60, a casting product unloading unit 70, an image capturing and determining unit 80, and a mold release agent applying unit 90. The injection unit 50 and the mold clamping unit 60 are arranged in the vertical direction (vertical casting device).

[0075] The injection unit 50 is equipped with a melt holding furnace 51, which stores the melt M inside and forms a pressurized chamber 52 above the melt M. By introducing the pressurized gas with adjusted pressure and flow rate from the pressurized gas supply unit 55 to the pressurized chamber 52 via the pressurized gas control unit 54, the pressure in the pressurized chamber 52 rises, pushing the melt M. The pushed melt M flows in the melt supply pipe 53 and is injected and filled into the mold cavity CV (referred to as a filling action). The melt M in the melt holding furnace 51 and the melt M flowing in the melt supply pipe 53 are maintained at a specified temperature by a temperature adjustment mechanism not shown in the figure. In addition, the melt M is regularly replenished to the melt holding furnace 51 from the melting mechanism not shown in the figure. In addition, in order to prevent oxidation of the melt M, it is preferred that an inert gas such as argon or nitrogen is used as the pressurized gas.

[0076] in addition, Figure 5 The ejection unit 50 shown in the figure introduces pressurized gas and fills the melt M into the mold cavity CV, but it is not limited to this. For example, it can also be in such a form that a piston-type pressurizing mechanism is connected to the melt supply pipe 53 in the melt M in the melt holding furnace 51, and the melt M is pushed by the piston operation to perform the filling action through the melt supply pipe 53. Alternatively, it can also be in such a form that a conveying mechanism such as an electromagnetic pump is used to perform the filling action from the melt holding furnace 51 through the melt supply pipe 53. In addition, for example, it can also be in such a form that Figure 1 The injection unit 10 shown is vertically arranged below the mold clamping unit 60 for filling. In this case, the injection sleeve 11 is tilted to a predetermined position with the pouring port 16 closed, and the melt M is supplied from the end of the injection sleeve 11. Then, the injection sleeve 11 is combined with the mold cavity CV to perform the filling operation. Figure 1 Similarly, the injection unit 10 is disposed horizontally in a horizontal position, and is connected to the melt supply pipe 53 disposed vertically in the fixed platen 61 or the fixed mold 65 to perform the filling operation.

[0077] The mold clamping unit 60 is located above the injection unit 50, and is provided with a fixed platen 61 supporting a fixed mold 65, a movable platen 62 supporting a movable mold 66, and a mold clamping platen 63 supporting a mold clamping driving unit 67 in the vertical direction. The fixed platen 61 and the mold clamping platen 63 are connected by a plurality of tie rods 64 penetrating the movable platen 62. The mold clamping control unit 68 operates the mold clamping driving unit 67, and controls the sliding of the movable platen 62 in the mold opening and closing direction using the tie rods 64 as guides. Here, regarding the sliding of the movable platen 62, the sliding approaching the fixed platen 61 is defined as a mold clamping action, and the action of separating from the fixed platen 61 is defined as a mold opening action. Through the mold clamping action of the movable platen 62, the fixed mold 65 and the movable mold 66 are clamped to form a mold cavity CV. The end of the melt supply pipe 53 is connected to the gate YG of the mold cavity CV, and the melt M in the melt holding furnace 51 is filled into the mold cavity CV through the melt supply pipe 53 and the gate YG. In addition, the pressurized gas control unit 54 is operated to discharge the pressurized gas from the pressurized chamber 52, thereby reducing the pressure in the pressurized chamber 52, whereby the melt M in the melt supply pipe 53 flows back and is recovered in the melt holding furnace 51. In addition, the vacuum suction of the mold cavity CV and the filling operation can also be combined by using a vacuum suction mechanism not shown in the figure.

[0078] Here, the mold clamping unit 60 is a form in which the movable platen 62 is opened and closed by a hydraulic cylinder driven by hydraulic pressure, as in the first and second embodiments. However, for example, a form in which a toggle mold clamping mechanism is provided instead of a hydraulic cylinder, or a power transmission mechanism such as an electric motor and a ball screw is combined instead of a hydraulic drive. In addition, a form in which the mold clamping drive unit 67 is arranged on the tie rod 64, and a connection mechanism such as a split nut is used between the tie rod 64 and the movable platen 62 to open and close the mold is also possible. In this case, the mold clamping platen 63 can be omitted.

[0079] In addition, the fixed mold 65 and the movable mold 66 are heated to a high temperature by the filling action of the melt M, similarly to the first and second embodiments. For example, when a melt M such as an aluminum alloy maintained at a melting temperature of 650 to 720°C is used, the surface temperature of the mold cavity CV during the mold opening action becomes a high temperature state of 450 to 550°C. In addition, the casting MP just after being removed from the mold cavity CV is in a high temperature state of 200 to 400°C. Therefore, in order to stabilize the surface temperature of the mold cavity CV and the temperature of the casting MP and shorten the casting cycle, it is preferred that a cooling mechanism including a cooling circuit, not shown in the figure, is provided in the fixed mold 65 and the movable mold 66.

[0080] like Figure 3As shown in (b), the casting unloading section 70 is configured to move along the direction of arrow B or arrow C, and is equipped with a product arm 71 that slides in the horizontal direction and a product fixture 72 supported by the product arm 71. Simultaneously with the mold opening action, or after the mold opening action, the unloading control section 74 operates the unloading drive section 73 to move the product arm 71, so that the product fixture 72 enters the space portion 29 surrounded by the fixed mold 65 and the movable mold 66 (referred to as an entry action). The casting MP is pushed out from the mold cavity surface CS of the movable mold 66 by means of an ejection mechanism (not shown in the figure) assembled on the movable mold 66 (referred to as an ejection action). In addition, at Figure 5 In the embodiment, the casting MP remains in the movable mold 66, and the casting MP is pushed out from the movable mold 66. However, for example, the casting MP may remain in the fixed mold 65, and the casting MP may be pushed out from the fixed mold 65. In this case, it is preferable to provide a reversing mechanism in the product fixture 72, and after the demolding action, the product fixture 72 is reversed while holding the casting MP. Figure 5 In the state shown, the image of the cast product MP is photographed at the demolding position. In the present embodiment, the operation of pushing out the cast product MP from the movable mold 66 will be described.

[0081] After the push-out action, or simultaneously with the push-out action, the carry-out control unit 74 operates the product fixture 72, and uses the product fixture 72 to grasp the material handle BK separated from the product surface SM of the casting MP, and separates the casting MP from the mold cavity CV (referred to as a demolding action). The position of this demolding action is defined as the demolding position. By grasping the material handle BK with the product fixture 72, the image photography of the product surface SM of the casting MP is not affected. After that, the carry-out control unit 74 operates the product arm 71 to carry the casting MP out of the space portion 29 surrounded by the fixed mold 65 and the movable mold 66 (referred to as a carry-out action). The position where the carry-out is completed is defined as the carry-out position. Figure 5 Indicates the state of the carry-out position. After that, the casting MP is transported to a predetermined position, and the casting MP continues to undergo subsequent processes such as casting burr treatment. Therefore, the casting carry-out section 70 is equipped with: a transport mechanism for transporting the casting MP in the subsequent process, a mechanism for adjusting the position of the entry action or the carry-out action and the demolding action, etc.

[0082] The image photography determination unit 80 is equipped with: an image photography unit 81, which captures an image of the casting MP at a specified photography position; an image data collection unit 82, which collects image data captured by the image photography unit 81; a mold residue determination unit 83, which determines whether there is a mold residue abnormality in which all or part of the casting MP remains in the mold cavity CV; and a determination display unit 84, which serves as a notification unit for displaying the determination result of the mold residue determination unit 83.

[0083] Here, the space 29 surrounded by the fixed mold 65 and the movable mold 66 is heated by the high-temperature mold cavity CV and the casting MP, and the field of vision is unclear due to air swaying and smoke generated from the attached release agent, which is not suitable for imaging the casting MP. Figure 5 As shown, the imaging unit 81 is configured to be able to perform imaging at a carry-out position separated from the space unit 29 in a high temperature state. Thus, a clear imaging of the casting MP can be performed, and the presence or absence of mold residual abnormality can be accurately determined. In addition, thermal damage to the imaging unit 81 can be reliably avoided.

[0084] In addition, when smoke is generated from the mold release agent attached to the casting MP and hinders image photography, air is sprayed toward the casting MP from the first air blowing mechanism 76 provided in the casting unloading section 70 to blow away the smoke before image photography is performed. As a result, clear image photography of the casting MP can be performed, and the accuracy of determining whether there is a mold residue abnormality can be further improved. In addition, air can be sprayed toward the unloading position, more preferably toward the casting MP at the unloading position, from the second air blowing mechanism 92 provided in the mold release agent coating section 90 waiting at a predetermined position to blow away the smoke.

[0085] In addition, the image photographing section 81 photographs the product surface SM of the casting MP from the front side in such a manner that the product clamp 72 holding the material handle BK is on the back side. Since the material handle BK is located at a position separated from the product surface SM, it has no influence on the image photographing of the product surface SM. However, the product arm 71 of the casting unloading section 70, the support and other structures, or the peripheral equipment related to the casting forming device 300, etc. are sometimes reflected in such a manner as to overlap with the back side of the casting MP. As a result, the product surface SM of the casting MP cannot be clearly imaged, and there is a concern that the accuracy of determining whether there is an abnormal mold residue is reduced. Therefore, a photography auxiliary plate 75 is provided in the casting unloading section 70 in such a manner as to overlap with the back side of the casting MP, and the image is photographed from the front side of the casting MP in a state in which the photography auxiliary plate 75 overlaps with the back side of the casting MP. As a result, the structures on the back side overlapping with the product surface SM of the casting MP are blocked from sight, such as Figure 2 As shown, it is possible to capture a clear image of the product surface SM of the cast product MP, and the accuracy of determining whether or not there is a mold residue abnormality can be improved.

[0086] In addition, Figure 5 In the embodiment, there is only one image capturing unit 81, but as in the first embodiment, a plurality of image capturing units 81 may be used to determine whether there is a mold residue abnormality. In addition, other aspects may be referred to the first embodiment and the same means may be adopted. For example, if the casting MP can be clearly imaged and the mold residue abnormality can be clearly determined, the photography auxiliary plate 75 may be omitted.

[0087] In addition, after the image of the cast product MP is taken by the image taking unit 81, the presence or absence of mold residue abnormality is determined as in the first embodiment. In addition, the image taking mechanism of the image taking unit 81 and the image analysis mechanism of the mold residue determination unit 83 can be the same as in the first embodiment.

[0088] Furthermore, by using the photography auxiliary plate 75 of a different color tone from the casting MP, the image data of the casting MP becomes clearer, and the accuracy of determining whether there is a mold residue abnormality can be further improved. In addition, for example, when an infrared thermal camera is used as the image capturing unit 81, the temperature difference between the casting MP and the photography auxiliary plate 75 becomes significant, and the thermal image data of the casting MP can be made clear.

[0089] like Figure 3 As shown in (a), the determination result of the mold residue determination unit 83 is displayed on the screen as image data by the determination display unit 84. When the mold residue determination unit 83 determines that there is no mold residue abnormality, the determination display unit 84 displays the screen as normal. Figure 5 As shown, the release agent coating unit 90 waiting at a predetermined position enters the space 29 surrounded by the fixed mold 65 and the movable mold 66, and starts the preparation process of spraying air from the second air blowing mechanism 92 to clean the mold cavity CV, and spraying the release agent from the release agent spray nozzle 91 to coat the release agent, and the casting operation continues. By determining whether there is a mold residue abnormality at the shortest distance to carry out the unloading position, the determination time can be minimized, and the production efficiency of the casting can be maintained at a high state.

[0090] In addition, the predetermined position of the release agent coating portion 90 is as follows: Figure 3As shown in (b), when the action position of the casting unloading unit 70 is in the B direction, it is arranged in the C direction, and when the casting unloading unit 70 is in the C direction, it is arranged in the B direction. That is, preferably, the casting unloading unit 70 and the release agent coating unit 90 are arranged at positions where the action directions do not interfere with each other. In addition, when the casting unloading unit 70 and the release agent coating unit 90 are arranged to have the same entry action and unloading action, interference can be avoided by first operating the casting unloading unit 70, setting a time difference, and then operating the release agent coating unit 90. However, since the casting forming cycle will be longer by an amount equivalent to the time difference, when the casting forming cycle is given priority, it is preferred that the casting unloading unit 70 and the release agent coating unit 90 are arranged differently.

[0091] When the mold residue determination unit 83 determines that there is a mold residue abnormality, such as Figure 3 As shown in (a), the screen display of the judgment display unit 84 is abnormal. At the same time, the image data of the casting MP or the image data of the mold cavity CV of the movable mold 66 (or the fixed mold 65) for demolding the casting M is displayed. In the image data displayed on the screen, the position of the mold residual abnormality is displayed in a manner that can identify. Figure 3 In (a), the defective venting groove GR is displayed as a mold residual abnormality. In addition, the operation of the casting is stopped, and an alarm is sounded to draw the attention of the molding operator. The molding operator can accurately identify the position where the mold residual abnormality occurs by looking at the display screen of the judgment display unit 84, and can quickly remove the mold residual venting groove GR from the mold cavity CV. In this way, the operation stop time of the casting can be minimized, and the production efficiency of the casting can be restored to a high state.

[0092] Here, as an application of the third embodiment, a form of performing image photography of the casting MP at the demolding position is described. After the mold opening action or simultaneously with the mold opening action, the casting carrying-out unit 70 is moved in. At the same time, the image photography unit 81 is arranged at a position away from the demolding position so as to be able to photograph at the demolding position. After the ejection action of the casting MP or simultaneously with the ejection action, the demolding action of the casting MP is performed by the product fixture 72. In this state, the image photography is performed to determine whether there is a mold residue abnormality, thereby further shortening the determination time. In this case, the swing of the heated air rising from the fixed mold 65 and the smoke from the mold release agent can be shielded by the photography auxiliary plate 75, and clear image photography of the casting MP can be expected. Furthermore, air is sprayed from the first blowing mechanism 76 or the second blowing mechanism 92 to blow away the swing of the air or the smoke, thereby assisting in clear image photography. As a result, the determination accuracy of the mold residue abnormality can be improved. Furthermore, the time until image capture can be shortened, and the release agent application unit 90 can be moved in simultaneously with the unloading operation of the cast product unloading unit 70, thereby reliably shortening the casting cycle.

[0093] In any of the first to third embodiments, the determination of the presence or absence of mold residue abnormality is performed based on the image photography of the casting MP. However, for example, the image photography unit (41, 81) may also perform image photography of the mold cavity CV to determine the presence or absence of mold residue abnormality after the casting MP is carried out or after the preparatory process such as cleaning and mold release agent coating by the mold release agent coating unit 90. In this case, air is sprayed from the first air blowing mechanism (36, 76) or the second air blowing mechanism 92 to the mold cavity CV, thereby blowing away the sway of the heated air or the smoke from the mold release agent, etc., to ensure a clear field of view, and to perform clear image photography of the mold cavity CV, thereby ensuring the accuracy of the determination of the presence or absence of mold residue abnormality.

[0094] [Effect]

[0095] (1) The casting forming device 100 (200, 300) is equipped with a fixed mold 25, 65 and a movable mold 26, 66, and a mold cavity CV partitioned by them, and a molten material M is filled into the mold cavity CV and cooled and solidified to form a casting MP, wherein the casting forming device 100 (200, 300) is equipped with:

[0096] a release agent coating unit 90 for coating a release agent on a surface of the mold cavity CV;

[0097] The casting MP unloading section 30, 70 is used to unload the casting MP;

[0098] Image photography unit 41, 81;

[0099] An image data collection unit 42, 82, the image data collection unit 42, 82 collects the captured images;

[0100] a mold residue determination unit 43, 83 for determining a mold residue abnormality in which a portion of the cast product MP remains in the mold cavity CV; and

[0101] a notification unit (determination display unit) 44, 84, which displays or notifies the outside whether or not the determined mold residual abnormality exists,

[0102] The image capturing units 41 and 81 capture images of the cast product MP.

[0103] The mold residue determination unit 43, 83 determines whether or not there is a mold residue abnormality by comparing a preset reference image with the captured actual image.

[0104] When detecting mold residue by photographing the mold after casting, the casting MP needs to be moved to a position where it does not become an obstacle to the photographing, which may cause time loss due to the movement and make it difficult to perform rapid photographing and abnormality determination. This problem becomes particularly prominent when mold residue remains inside the mold.

[0105] In this regard, in the present application, the casting MP is photographed instead of the mold, so that even if there is mold residue in a portion inside the mold corresponding to the casting MP, it is possible to quickly determine that the mold residue is abnormal, thereby shortening the casting process time. In addition, the operator can be appropriately notified of the abnormality by means of a display or other notification means.

[0106] (2) After casting, the space formed by separating the fixed mold 25, 65 and the movable mold 26, 66 is referred to as the space portion 29.

[0107] The image capturing units 41 and 81 capture an image of the cast product MP located in the space 29 .

[0108] By performing imaging in the space 29 without greatly moving the cast product MP, the time-shortening effect of the entire casting process including abnormality determination becomes more significant.

[0109] (3) Blowing mechanisms 36, 76, 92 are provided to blow gas toward the casting MP. Smoke and the like due to heat or volatilization of the mold release agent remain around the casting MP immediately after casting, which often obstructs the view optically and is not a good environment for photography. Therefore, by blowing gas such as air toward the casting MP, photography can be performed in a state where the swaying of the ambient atmosphere caused by heat and the influence of smoke and the like are reduced, and image determination with high accuracy can be performed.

[0110] (4) A photography auxiliary plate 35, 75 is provided adjacent to the casting MP.

[0111] The image capturing units 41 and 81 are provided so as to be able to capture an image of the surface of the cast product MP with the photography auxiliary plates 35 and 75 as a background.

[0112] Since a die-casting machine has a plurality of other metal devices disposed in the conveying path of the cast product MP, when photographing the cast product MP, the boundaries with these devices are often unclear, and there is a concern that the judgment of mold residue using the image may become inaccurate. Therefore, by providing the photography auxiliary plates 35 and 75, when photographing the cast product MP, the reflection of other devices can be blocked, and the surface image of the cast product MP, especially the periphery of the cast product MP, becomes clear. Therefore, the judgment accuracy of abnormalities such as mold residue based on the image can be improved.

[0113] Although the preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the above embodiments. Various changes or improvements can be made to the above embodiments.
