<Casting mold wash and application method>
Next, the coating agent and the method of applying the coating agent will be described.
A casting mold wash is a slurry-like material that is applied to the surfaces of molds and cores. The purpose of applying the mold wash is to prevent the molten metal from entering between sand grains, prevent physical or chemical seizure, and prevent the mold from sticking by applying it between the molten metal and the mold material of the casting. By shielding the generated gas, the casting surface is improved by preventing gas defects from occurring in the casting. In addition, in the mold coating application of the disappearing model casting method, which is applied to the disappearing model, when the molten metal is filled in the space after the disappearing model is pyrolyzed by the heat of the molten metal, the gas generated by the thermal decomposition of the model is properly removed. When the mold is filled with molten metal, it is applied to prevent the molten metal from entering the mold.

Methods of applying the coating agent to the mold or the disappearing model include, for example, immersing in the coating agent (dipping method), applying with a brush, spray coating, and pouring the coating agent (Bukkake method). There are other methods. In the present embodiment, a site where a mold coating agent is applied using the Bukkake method will be described as an example, but the present invention is not limited to this. Other methods may be used, and can be selected according to facility environment, casting shape, and the like.

A wash comprises a refractory aggregate, a binder, and a solvent. The wash may further comprise dispersants and surfactants as additives.

Refractory aggregates include, for example, at least one of zircon, silica, talc, alumina, mullite, magnesia, and graphite. The refractory aggregate has an average particle size of about 0.5 μm to 50 μm. The refractory aggregate may also contain a thickening agent, thereby having thixotropic properties.

Examples of binders include water-soluble polymers such as sodium polyacrylate, starch, methylcellulose, polyvinyl alcohol, sodium alginate and gum arabic, and various resin emulsions such as acrylic resin emulsions, urethane resin emulsions and vinyl acetate resin emulsions. Using one or more of natural polymers such as gum arabic and polysaccharides, organic polymers such as phenol resin, furan resin, rosin and petroleum resin, and inorganic binders such as ethyl silicate and sodium silicate. can be done.

Solvents include either alcohols such as methanol, ethanol, propyl alcohol, or water, and are removed from the mold by igniting and drying after applying the coating agent, or by heating and drying with a burner, hot air, etc. be.

<Concentration adjustment of coating agent>
The wash agent is prepared in the form of a high-solids paste or a concentrated dispersion by mixing the above materials, and is diluted with a solvent to form a slurry having a predetermined concentration before use in the coating operation. . The optimum concentration varies depending on factors such as the method of coating the mold, the shape of the mold, the grain size of the sand, the casting material, and the environment of the work site (air temperature, liquid temperature, humidity, etc.). be.

In addition, the concentration of the washing agent may gradually increase during the coating operation due to evaporation of the solvent contained in the washing agent. As the concentration of the wash changes, the viscosity of the wash also changes. The viscosity of the wash affects the surface smoothness and thickness of the resulting coating film, as well as the depth of penetration into the mold, so it is necessary to adjust the concentration of the wash to keep it constant throughout the process. . If the concentration of the washing agent becomes higher than the predetermined value, it is adjusted by diluting with a solvent even during the operation. On the other hand, when the concentration is lower than the predetermined value, paste or concentrated dispersion is added to adjust.

In this embodiment, the Baume degree is used as a value indicating the concentration of the coating agent. The Baume degree is one of the measurement units indicating the specific gravity of a liquid, but it is different from the so-called specific gravity. In general, a Baume meter is directly floated on the coating liquid to measure the Baume degree, but it can be affected not only by the specific gravity but also by the viscosity of the coating liquid.
The Baume degree is a calculated value D2 calculated from the measured value D1 of the sensor 90 (in this embodiment, the specific gravity or a value correlated to the specific gravity). As shown in FIG. 4(b), the relationship between the concentration (calculated value D2) and the specific gravity (measured value D1) of the wash agent has a non-linear relationship.

The relationship between the concentration and the specific gravity of the washing agent varies depending on the components of the washing agent and the temperature. Therefore, the information processing apparatus 100 of the present embodiment has a conversion table 106 (FIG. 4A) as a conversion rule for converting the measured value D1 of the specific gravity of the wash agent into a Baume degree (calculated value D2). . The conversion table 106 associates the concentration (Baume degree) and the specific gravity of the wash agent. For example, the conversion table 106 is prepared for each component composition (by type) of the wash agent. The processing unit 104 calculates at least one of the Baumé degree, the specific gravity, and the viscosity of the casting wash using the conversion table 106 corresponding to the casting wash.

Also, the conversion rule may be a graph created from the conversion table 106 instead of the conversion table 106 . The processing unit 104 may use a graph created from the conversion table 106 to convert the measured value D1 into the calculated value D2.

Furthermore, the information processing apparatus 100 may further include a correction table (not shown) corresponding to temperature as a conversion rule. After calculating the Baume degree of the coating agent from the measured value D1 of the sensor 90 using the conversion table 106, the processing unit 104 further corrects the Baume degree using the correction table to obtain the calculated value D2. good.

In another embodiment, the processing unit 104 may calculate the specific gravity and viscosity of the wash from the measured value D1 of the sensor 90 . When the relationship between the measured value D1 of the sensor 90 and the value indicating the concentration of the wash agent is linear, the conversion table 106 may not be used, and an arithmetic expression may be used for calculation.

A plurality of conversion rules linked to each type of wash agent (by component composition) may be stored in advance in the storage 23 of the controller 20 . Alternatively, it may be stored in the storage 23 each time according to the type of washing agent to be used. The conversion rule may be read from a recording medium and written to the storage 23 or memory 22, or may be downloaded to the storage 23 or memory 22 via a network. When a plurality of conversion rules are held in the storage 23, the setting screen of the controller 20 is configured so that the operator can select the type of wash agent to be used or the conversion rule. When the operator selects the type of wash agent, a conversion rule corresponding to the selected wash agent type is used.

The index related to the physical property value of the casting mold wash, which is the measured value D1 measured by the sensor 90, is, for example, at least one of density, specific gravity, and a value correlated with specific gravity. In this embodiment, the index is specific gravity. The values output from sensor 90 may be either analog output values or digital data values.

<Sensor>
The sensor 90 is, for example, a transmission type density meter using an X-ray or γ-ray source, which can be attached to the outside of the pipe for measurement and can measure the density of the liquid flowing through the pipe without contact. In this embodiment, a transmission-type density meter using a γ-ray source is used as the sensor 90, but the present invention is not limited to this, and a vibration-type density meter may be used. The sensing part is exposed inside the pipe and comes into contact with the mold wash.
Sensor 90 is, for example, a sensor that uses a gamma ray source of 3.7 megabecquerels or less.

FIG. 5 is a cross-sectional view showing an example of attaching the sensor 90 to a pipe. A pipe 94 to which the sensor 90 is attached connects the agitating tank 214 (storage tank) that stores the wash agent and the treatment area where the treatment tank 220 is installed and the wash agent is applied to the mold or the disappearing pattern. This is the flow path during the coating operation of the wash agent. On the other hand, during adjustment of the washing agent, the flow path of the pipe 94 is switched to circulate the washing agent in the adjustment tank 212 .

A gamma ray source 92 and a sensor 90 are attached to sandwich a pipe 94 from both sides. A γ-ray source 92 is arranged on one side of the pipe 94 , and a sensor 90 is arranged on the other side facing the γ-ray source 92 across the pipe 94 .

The piping 94 preferably has an inner diameter in the range of 15 to 100 mm, for example. 20 to 50 mm is more preferable from the viewpoint of easiness in measuring physical properties of the coating agent. The smaller the inner diameter, the smaller the dose of γ-rays. Moreover, the larger the inner diameter, the smaller the measurement error of the sensor 90 .

<Piping example at work site>
At the work site, the flow path of the piping through which the mold wash agent flows is switched during the coating operation and during the concentration adjustment.
Similar to FIG. 1, FIG. 6 is a diagram showing an example of the configuration and piping of a work site for applying a mold wash to a mold. FIG. 1 shows an example in which the washing agent is being applied, and FIG. 6 shows an example in which the washing agent is being adjusted.

A plurality of pumps and a plurality of valves are provided in the piping through which the washing agent or solvent passes, and the flow path of the washing agent is switched by opening/closing the valves and controlling the operation and stop of the pumps. The adjustment tank 212 and the stirring tank 214 are provided with stirring blades 202 for stirring the coating agent in the tanks, and the stirring blades 202 are provided with motors for controlling rotation.

The control panel is provided with operation switches for controlling the opening and closing of valves and controlling the operation and stop of pumps or motors. An operator can control the operation of each valve, each pump, or each motor by operating the operation switch. Alternatively, the control board may be controlled by the controller 20 . The controller 20 may transmit a valve opening/closing instruction or a pump or motor on/off instruction to the control panel for control. Alternatively, the controller 20 may control the valves, pumps, or motors without using the control panel.

During the coating operation in FIG. 1, all the valves Va among the valves in the piping are opened and all the valves Vb are closed. Also, in the example of FIG. 6 during preparation of the wash agent, all valves Va are closed and all valves Vb are opened. Further, in FIGS. 1 and 6, the valve Vc is controlled by an operator or an open/close instruction from the controller 20 .

<Work procedure>
The work procedure at the work site will be explained. FIG. 7 is a flow chart showing an example of the procedure of the coating agent adjustment step ST1 and coating step ST2. In the drawing, steps indicated by solid lines indicate processing procedures of the information processing apparatus 100 , and steps indicated by broken lines indicate work processes or processing procedures other than the processing of the information processing apparatus 100 . The coating agent adjusting step ST1 includes steps S101 to S107, and the coating step ST2 includes steps S111 to S117.

<Washing agent adjustment step ST1>
First, the washing agent adjusting step ST1 will be described with reference to FIGS. 6 and 7. FIG.
In step S<b>101 , a paste or a concentrated dispersion of a wash agent (not shown) is put into the adjusting tank 212 by an operator. A solvent for diluting the washing agent is contained in the solvent bath 210 . Then, the solvent is supplied from the solvent tank 210 to the adjustment tank 212 by a constant amount by operating the pump P1. The amount of solvent input is controlled by the operation of pump P1. The amount of solvent to be added may be controlled automatically by the controller 20 or manually operated by an operator using an operation switch on the control panel.

Then, the rotation of the stirring blade 202 is controlled by the motor M1 to mix the washing agent and the solvent. Furthermore, the pump P2 is operated to discharge the washing agent in the adjusting tank 212 into the pipe, and the washing agent passes through the pipe to which the sensor 90 is attached. Then, the washing agent returns to the adjusting tank 212 via the sensor 90 and circulates.

In step S103, the sensor 90 measures the specific gravity of the coating agent discharged from the adjustment tank 212 and flowing through the pipe. Acquisition unit 102 acquires measured value D<b>1 from sensor 90 . The processing unit 104 uses the conversion table 106 to convert the specific gravity (measured value D1) into Baume degree (calculated value D2).

Until the Baume degree reaches the set value (or within the allowable range of the set value) (NO in step S105), the pump P1 is operated to feed the solvent from the solvent tank 210 to the adjustment tank 212 by a constant amount. The width of the allowable range of error may be further set for the set value of the Baume degree. In step S105, it is determined whether the Baume degree is within the set value by determining whether the Baume degree is within the allowable range of the set value. may be

When the Baume degree reaches the set value (or within the allowable range of the set value) (YES in step S105), the pumps P1 and P2 are stopped, and the process proceeds to step S107. In step S107, the opening and closing of each valve is switched to switch from the flow path shown in FIG. 6 to the flow path shown in FIG.

Further, if it takes a certain amount of time for the change in the concentration of the wash agent due to the addition of the solvent to be reflected in the measured value D1 of the sensor 90, the determination in step S105 is performed in order to stabilize the measured value D1. It is desirable to do this after some time has passed. For example, the acquisition unit 102 acquires the operation signal and the stop signal of the pump P1 from the control panel, receives the operation signal of the pump P1, and after a predetermined time has passed since the stop signal of the pump P1 is received, A measurement value D1 of the sensor 90 is acquired.

In addition, during the adjustment step ST1, when the agitating tank 214 contains the washing agent, the coating operation of pouring the washing agent onto the mold can be performed in the processing tank 220 in the same manner as in the later-described coating step ST2. .

<Washing agent application step ST2>
After the flow path is switched, the coating step ST2 of the coating agent is performed. The coating step ST2 will be described with reference to FIGS. 1 and 7. FIG.
The coating agent whose concentration has been adjusted in the adjustment step ST1 is transferred from the adjustment tank 212 to the stirring tank 214 and stored in the stirring tank 214 (step S111). Further, even during the coating step ST2, when the washing agent in the stirring tank 214 runs out, the pump P2 is operated and the valve Vc is opened to supply the washing agent in the adjusting tank 212 to the stirring tank 214. . When a predetermined amount of the washing agent is contained in the stirring tank 214, the pump P2 is stopped and the valve Vc is also closed.

In addition, the washing agent in the stirring tank 214 is appropriately stirred by the stirring blade 202 whose rotation is controlled by the motor M2 so that the concentration of the washing agent in the container is not uneven during the operation.

Next, the pump P3 is operated to discharge the washing agent in the agitation tank 214 into the piping, and the washing agent is passed through the piping to which the sensor 90 is attached. Then, the washing agent passes through the sensor 90, passes through the filter tank 216, and returns to the stirring tank 214 for circulation.

In step S113, the sensor 90 measures the specific gravity of the washing agent discharged from the stirring tank 214, flowing through the piping, and transferred to the processing tank 220, that is, the washing agent used in the coating operation. Acquisition unit 102 acquires measured value D<b>1 from sensor 90 . The processing unit 104 uses the conversion table 106 to convert the measured value D1 into a Baume degree (calculated value D2).

While the Baume degree is within the set value (or within the allowable range of the set value) (YES in step S117), the coating agent in the stirring tank 214 is used to coat the mold in the processing tank 220 (step S115). ). A coating operation is performed in the processing bath 220 . In the treatment tank 220, the washing agent prepared in the stirring tank 214 flows in and out from a hose by opening and closing a manual valve Vd (a so-called faucet), and the operation of pouring the washing agent onto the mold is performed.

(Fifth embodiment)
FIG. 17 is a functional block diagram showing the logical configuration of the information processing apparatus 100 of this embodiment. The information processing apparatus 100 of this embodiment is the same as any of the above-described embodiments, except that it has a configuration for adjusting the concentration of the washing agent during the coating operation. In the configuration example of FIG. 17, the configuration is combined with the configuration of FIG. The information processing apparatus 100 of the present embodiment can be combined with any of the above embodiments and other embodiments described later within a consistent range.

The information processing apparatus 100 of FIG. 17 includes the same obtaining unit 102 and processing unit 104 as in the above-described embodiment of FIG. 3, and further includes a control unit . The controller 130 uses the calculated value D2 to control the addition amount or flow rate of the solvent or high-concentration wash to adjust the calculated value D2 of the casting wash.

As described above, since the concentration of the wash agent in the stirring tank 214 changes during the coating operation, the concentration may deviate from the set value or the allowable range of the set value. The control unit 130 adds a solvent for dilution to the stirring tank 214 and controls the flow rate of the solvent so that the concentration of the wash agent is within the set value or within the allowable range of the set value. Alternatively, the controller 130 may instruct the operator to manually add the solvent. When the concentration of the washing agent becomes lower than the set value, the washing agent having a higher concentration than the washing agent in the stirring tank 214 may be added to the stirring tank 214 through a pipe from a container (not shown). In addition, the control unit 130 may instruct the operator to manually add the paste of the wash agent. A constant amount of the solvent or high-concentration mold wash may be added at predetermined intervals.

The operator is notified, for example, by the display processing unit 110 causing the display unit 27 to display an adjustment instruction (type and amount of solvent or high-concentration washing agent), or to display that the concentration is high or low. It is done by

FIG. 18 is a flow chart showing an example of the density adjustment process procedure in the information processing apparatus 100 . This flow is started when the Baume degree deviates from the set value or the allowable range of the set value in step S117 of FIG. 7 (NO in step S117).

First, when the calculated value D2 (here, Baume degree) calculated by the processing unit 104 exceeds the set value or the allowable range of the set value (YES in step S201), the control unit 130 instructs the display processing unit 110 to , to display on the display unit 27 a content notifying that the degree of Baume is high (step S203). For example, screen 200 in FIG. 10 is an example.

Then, the control unit 130 opens the valve Va on the pipe leading from the solvent tank 210 to the filtration tank 216, operates the pump P1, and adds the solvent to the stirring tank 214 (step S205).

On the other hand, if the calculated value D2 (here, the Baume degree) calculated by the processing unit 104 does not exceed the set value or the allowable range of the set value (NO in step S201), the Baume degree is set to the set value or the set value. is below the allowable range (step S207). If the Baume degree is below the set value or the allowable range of the set value (YES in step S207), the control unit 130 causes the display processing unit 110 to display on the display unit 27 a content notifying that the Baume degree is low. (Step S209).

Then, the control unit 130 operates the pump on the pipe that flows the high-concentration washing agent from a container (not shown) to the stirring tank 214, opens the valve, and adds the high-concentration washing agent to the stirring tank 214. (Step S211).

If the Baume degree is not below the set value or the allowable range of the set value (NO in step S207), after either step S205 or step S211, in step S213, the control unit 130 determines whether the Baume degree is the set value or Determine whether or not the set value is within the allowable range. If it is within the set range (YES in step S213), the process returns to step S113 in FIG. On the other hand, if it is not within the set range (NO in step S213), the process returns to step S201.

In this embodiment, the control unit 130 monitors the concentration of the wash agent during the coating operation so that it falls within the set value or the allowable range of the set value, and if the set value or the allowable range of the set value is deviated, The concentration can be adjusted by adding a solvent or a high-concentration coating agent to the stirring tank 214 .
According to this configuration, it is possible to maintain a constant value by adjusting the concentration of the coating agent. Therefore, since the concentration of the mold wash agent can be maintained at an appropriate value, the casting surface can be maintained in good condition, and the quality of the mold can be maintained.

In these examples as well, the controller 130 controls the addition amount or flow rate of the solvent or the high-concentration mold wash agent in the same manner as in the above-described embodiments. Also, in the above example, the piping was switched between during coating of the washing agent (FIG. 1) and during preparation of the washing agent (FIG. 6), but in the following examples, switching is unnecessary.

(Configuration example 1)
FIG. 19 shows a configuration example in which concentration adjustment control of the washing agent in the stirring tank 214 is performed by solvent dilution. In the example of FIG. 19, a solvent bath 210, a stirring bath 214, and a processing bath 220 are provided at the work site. That is, in this example, the adjustment tank 212 and the filtration tank 216 of FIG. 1 are not included. The valve Vb is opened during the preparation of the wash and closed during the application of the wash.

During the coating of the coating agent, the pump P3 is operated to allow the coating agent in the stirring tank 214 to flow in and out of the hose by opening and closing the manual valve Vd (a so-called faucet), thereby pouring the coating agent onto the mold. will be The remainder of the wash applied to the mold is discharged through holes in the bottom of treatment vessel 220 and returned to agitation vessel 214 . In addition, the washing agent in the stirring tank 214 is appropriately stirred by the stirring blade 202 whose rotation is controlled by the motor M2 so that the concentration of the washing agent in the container is not uneven during the operation.

In addition, in order to measure the specific gravity of the coating agent used in the coating operation, that is, the coating agent contained in the stirring tank 214, the pump P4 is operated to transfer the coating agent in the stirring tank 214 to the pipe. It is discharged and passed through the piping to which the sensor 90 is attached. Then, the washing agent returns to the stirring tank 214 via the sensor 90 and circulates. A sensor 90 measures the specific gravity of the wash agent flowing through the pipe. The control of the pump P4 may be selected from automatic control by the controller 20 and manual operation of the operation switch on the control panel by the operator.

In order to dilute the concentration of the washing agent in the stirring tank 214, the pump P1 is operated to feed the solvent from the solvent tank 210 into the stirring tank 214 by a constant amount. The amount of solvent input is controlled by the operation of pump P1. The amount of solvent to be added may be controlled automatically by the controller 20 or manually operated by an operator using an operation switch on the control panel.

In this manner, in the example of FIG. 19, the concentration adjustment control is performed by diluting the washing agent in the stirring tank 214 with the solvent.

(Configuration example 2)
FIG. 20 shows a configuration example for performing adjustment control for increasing the concentration of the washing agent. In the example of FIG. 20, a solvent tank 210, an adjustment tank 212, a stirring tank 214, and a treatment tank 220 are provided at the work site. In other words, the adjustment tank 212 is added to the example of FIG. The adjustment tank 212 contains a coating agent having a higher concentration than the coating material in the stirring tank 214 . The valves Vb and Vc are opened during the preparation of the wash and closed during the application of the wash.

Transfer of the washing agent from the stirring tank 214 to the treatment tank 220 during the coating operation of the washing agent and transfer of the washing agent for measuring the concentration of the washing agent in the stirring tank 214 are described above. It is the same as FIG.

Adjustment control for increasing the concentration of the coating agent in the stirring tank 214 is performed by opening and closing the valve Vc to introduce the high-concentration coating agent from the adjusting tank 212 into the stirring tank 214 . Further, adjustment control for thinning the concentration of the washing agent is performed by adding the above solvent. During concentration adjustment, the coating agent in the stirring vessel 214 is appropriately stirred by the stirring blade 202 whose rotation is controlled by the motor M2. In addition, when adjusting the high concentration of the coating agent in the adjustment tank 212, or to prevent the concentration of the coating agent from being uneven in the container, the rotation of the coating agent in the adjustment tank 212 is controlled by the stirring blade 202 whose rotation is controlled by the motor M1. The wash is appropriately agitated.

In this manner, in the example of FIG. 20, the coating agent concentration adjustment control is performed by charging the high-concentration coating agent into the stirring tank 214 .

(Configuration example 3)
FIG. 21 shows a configuration example in which concentration adjustment control of the coating agent is performed in the adjusting tank 212 .

That is, this example does not include the filter tank 216 of FIG. In the example of FIG. 20, the washing agent for the coating operation was prepared in the stirring tank 214, but in this example, the concentration-adjusted washing agent for the coating operation is prepared in the adjustment tank 212, and the washing agent is prepared before application. Alternatively, it is different from the example of FIG. 20 in that the washing agent is put into the stirring tank 214 from the adjusting tank 212 during the coating operation. In addition, in the example of FIG. 1, the concentration of the washing agent in the stirring tank 214 is also measured. differ from The valve Vb is opened during the preparation of the wash and closed during the application of the wash.

Transfer of the washing agent from the stirring tank 214 to the processing tank 220 during the coating operation of the washing agent is the same as in FIG. 19 described above. In addition, concentration measurement is performed not for the washing agent in the stirring tank 214 but for the washing agent in the adjustment tank 212 . The pump P2 is operated to discharge the washing agent in the adjustment tank 212 into the pipe and pass through the pipe to which the sensor 90 is attached. Then, the washing agent returns to the adjusting tank 212 via the sensor 90 and circulates. A sensor 90 measures the specific gravity of the wash agent. The control of the pump P2 may be selected from automatic control by the controller 20 or manual operation of the operation switch on the control panel by the operator.

Next, the concentration of the washing agent is adjusted by putting a solvent or a high-concentration washing agent into the adjustment tank 212 . During the dilution process with the solvent, the solvent is supplied from the solvent tank 210 to the adjustment tank 212 by a constant amount by operating the pump P1. The amount of solvent input is controlled by the operation of pump P1. The amount of solvent to be added may be controlled automatically by the controller 20 or manually operated by an operator using an operation switch on the control panel.

The control for increasing the concentration of the washing agent is performed by the same control as in the above-described fifth embodiment. That is, a high-concentration coating agent is put into the adjusting tank 212 from a container (not shown). When a high-concentration coating agent or solvent is put into the adjustment tank 212, or to prevent uneven concentration of the coating agent in the container, the inside of the adjustment tank 212 is stirred by a stirring blade 202 whose rotation is controlled by a motor M1. is appropriately agitated.
