[0060] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] The present application proposes a pouring automatic control system, which realizes automatic control of material input into the mold cavity through data interaction between the main control unit and the injection control module, temperature control module, vacuum control module, etc., and then monitors the changes in the mold cavity in real time, and adjusts the temperature, vacuum, etc. in a timely and automatic manner when necessary, so that the automatic pouring process of the product is more automatic and accurate, thereby making the qualified rate of the obtained cast products higher.

[0062] The automatic pouring control system is described below in conjunction with some specific embodiments.

[0063] Figure 1A structural schematic diagram of a pouring automatic control system of an embodiment of the present application is shown. Exemplarily, the pouring automatic control system includes a main control cabinet 92, which includes a mold opening / closing control module 10, a parameter control module 20, a vacuum control module 30, an injection control module 40, and a curing control module 50; the pouring process includes a mold closing stage, at least one vacuuming stage, multiple injection stages, and multiple curing stages; when the product is poured, the mold opening / closing control module 10, the vacuum control module 30, the injection control module 40, and the curing control module 50 respectively perform corresponding mold closing operations, vacuuming operations, injection operations, curing operations, and mold opening operations according to different preset parameters in the parameter control module 20.

[0064] In this embodiment, if Figure 2 As shown, the parameter control module 20 includes a plurality of temperature preset units 21, a mold clamping pressure preset unit 22, a pouring pressure preset unit 23, a mold position preset unit 24, an injection position preset unit 25, a holding pressure preset unit 26 and a vacuum preset unit 27; the mold clamping pressure preset unit 22 is used to preset the mold clamping pressure at different stages, the pouring pressure preset unit 23 is used to preset the pouring pressure at the vacuuming stage and each injection stage, the mold position preset unit 24 is used to display the real-time position of the mold 90, the injection position preset unit 25 is used to display the real-time position of the injection nozzle, and the holding pressure preset unit 26 is used to preset the vacuuming stage and the pouring pressure at each injection stage. 6 is used to preset the holding pressure of each curing stage, the vacuum preset unit 27 is used to preset the vacuum degree of each stage, and each temperature preset unit 21 is used to preset the temperature parameters of each stage in the pouring process; each stage of the pouring process includes monitoring parameters; the monitoring parameters include temperature parameters, and the temperature parameters include the upper temperature of the mold, the lower temperature of the mold, the middle temperature of the mold, the injection nozzle temperature, the preset area temperature and the material temperature; among them, the upper temperature of the mold, the lower temperature of the mold, the middle temperature of the mold, the injection nozzle temperature, and the preset area temperature all need to set the minimum temperature, the maximum temperature and the set temperature.

[0065] In this embodiment, according to the pouring process of the pouring product, the mold 90 is divided into multiple parts; and according to the first feature of the pouring product and the stage characteristics of the pouring process, the preset temperature first parameter values ​​of the temperatures of multiple parts of the mold 90 at different stages are determined; for example, according to the characteristics of the pouring product, the feeding, exhaust, curing sequence and other factors are determined as the first feature, and the mold cavity is divided into several parts and regions; secondly, according to the stage characteristics such as the wall thickness of the product and the curing requirements, different temperature values, that is, the preset temperature first parameter values, are preset for each part and region at different stages of the pouring process. Dividing the mold into multiple areas can improve efficiency and product quality on the one hand, and reduce energy consumption. For example, 1-2 temperature sensing probes will be designed for each area to monitor the actual temperature of the mold 90 in real time, and the temperature parameters will be transmitted back to the parameter control module. The parameter control module will issue a heating instruction based on the difference between the preset temperature parameter value and the actual value of the temperature unit, and the heating rod will start working to heat the mold 90. When a higher temperature is required in a certain period of time, the heating power will be increased to control the temperature increase of the mold 90. When it rises to the preset temperature parameter value, the heating power will be reduced or stopped to keep the temperature of different parts of the mold 90 within the preset temperature range.

[0066] In this embodiment, the second parameter value of the preset temperature of the injection nozzle temperature at different stages is determined according to the second characteristic of the cast product and the stage characteristics of the casting process; for example, the second parameter value of the preset temperature of the injection nozzle temperature at different stages is determined according to the second characteristic of the cast product such as the material transfer process and the stage characteristics such as the requirements for the injection nozzle at different stages of the casting process. The third parameter value of the preset temperature of the material temperature at different stages is determined according to the characteristics of the material used for casting and the characteristics of the different stages of the casting process.

[0067] In this embodiment, the initial monitoring parameters of the mold closing stage include temperature parameters, mold position and injection position; the first monitoring parameters of each vacuuming stage include temperature parameters, mold closing pressure, pouring pressure, mold position and injection position; the second monitoring parameters of each injection stage include temperature parameters, mold closing pressure, pouring pressure and vacuum degree; the third monitoring parameters of each curing stage include temperature parameters and mold closing pressure.

[0068] In this embodiment, the parameter control module 20 also includes a detection unit 28 and a control unit 29; the detection unit 28 is used to detect the monitoring parameters of each stage in the pouring process in real time; the control unit 29 is used to control the corresponding structural components in real time so that the monitoring parameters reach the preset parameters of the corresponding stage. For example, in the injection stage, the temperature sensor senses that a certain temperature exceeds the preset value, and starts the heating or cooling control to keep the temperatures of each stage in the injection stage within the preset temperature range.

[0069] In this embodiment, the mold opening / closing control module 10 is used to control the mold 90 to close the mold when the mold closing requirements are met; and is also used to control the mold 90 to open the mold at the end of the curing stage. For example, after clicking the start button, the pouring automatic control system starts to run and enters the mold closing stage. In the mold closing stage, it is detected whether the mold position is in the mold opening state, that is, at 0 position, whether the injection position is in the non-injection state, that is, at 0 position, and whether the upper temperature of the mold, the middle temperature of the mold, the lower temperature of the mold, the injection nozzle temperature and the preset area temperature reach different initial temperature setting values, that is, to judge whether the initial monitoring parameters of the mold closing stage meet the mold closing requirements. If the initial monitoring parameters meet the mold closing requirements, the mold closing operation is performed according to the preset mold closing speed, the preset mold closing sequence (for example, the mold closing sequence of each oil cylinder), the preset mold closing pressure and the preset mold closing time and other preset mold closing parameters. At the end of the curing stage, the mold 90 is controlled to open according to the preset mold opening parameters such as the preset mold opening sequence and the mold opening pressure.

[0070] Generally speaking, the pouring process of all products requires vacuum. For example, a product has some inserts of different materials implanted in a certain area (especially some inserts are coated or wrapped with some special materials on the outer layer, which may prevent the volatilization of bubbles). When the pouring material fills the area, bubbles are likely to be generated, and the vacuum degree needs to be increased; or, when the pouring material is particularly thick, the vacuum degree needs to be increased. When the material is about to fill the mold cavity, the vacuum degree needs to be reduced to reduce the boiling of the material. Therefore, the vacuum degree requirements for multiple injection stages are different; but there will be individual products that perform a vacuum degree throughout the entire pouring process. Therefore, this embodiment does not limit whether the first vacuum degree, the second vacuum degree, etc. described below are the same.

[0071] After executing the mold closing operation, when the first preset requirement is met, the vacuum control module 30 performs a vacuum operation on the mold 90 to make the vacuum degree in the mold cavity reach the preset vacuum value, that is, when the mold 90 is closed and the clamping pressure reaches the preset pressure value, the first monitoring parameter is controlled to achieve the preset vacuum parameter of the vacuum stage; for example, whether the mold position is in the clamping state, that is, in position 1, whether the temperature of different parts of the mold, the material temperature, the injection nozzle temperature and the temperature of the special area reach the first preset temperature parameter and whether the clamping pressure reaches the preset vacuum parameter. When the above-mentioned first monitoring parameter reaches the first preset requirement, start the vacuum pump and perform a vacuum operation on the mold 90 to make the vacuum degree in the mold cavity reach the preset vacuum value.

[0072] In this embodiment, when the second preset requirement of each injection stage is met, the injection control module 40 performs the injection operation according to the preset injection speed and the preset pouring pressure corresponding to each injection stage.

[0073] In the initial injection stage, when the vacuum degree in the mold cavity is maintained at a preset vacuum value for a preset vacuum time, the second monitoring parameter is controlled to reach the preset initial value of the injection parameter in the initial injection stage, and the injection operation is performed according to the preset initial value of the injection speed and the preset initial value of the pouring pressure. For example, when the vacuum degree in the mold cavity is maintained at a preset vacuum value for a preset vacuum time, that is, when the vacuuming stage ends, the initial injection stage is entered, and the second monitoring parameter is controlled to reach the preset initial value of the injection parameter in the initial injection stage; it can be understood that the temperature of different parts of the mold, the material temperature, the injection nozzle temperature and the temperature of the special area, as well as the mold closing pressure, the pouring pressure and the vacuum degree are controlled to reach the preset initial value of the injection parameter, and when the above-mentioned second monitoring parameter reaches the preset initial value of the injection parameter, that is, the second preset requirement corresponding to the initial injection stage, the injection operation is performed according to the preset initial value of the injection speed and the preset initial value of the pouring pressure.

[0074] In each subsequent injection stage, when the injection time of the previous injection stage reaches the corresponding preset injection time, the second monitoring parameter is controlled to reach the preset injection parameter stage value corresponding to each subsequent injection stage, and the injection operation is performed according to the preset injection speed stage value and the preset pouring pressure stage value corresponding to each subsequent injection stage. For example, when the injection time of the initial injection stage reaches the corresponding preset injection time, the second monitoring parameter is controlled to reach the preset injection parameter initial value of the initial injection stage (control the temperature of different parts of the mold, the material temperature, the injection nozzle temperature and the temperature of the special area as well as the mold clamping pressure, the pouring pressure and the vacuum degree to reach the preset injection parameter stage value), if the second monitoring parameter of the subsequent injection stage reaches the corresponding preset injection parameter stage value, that is, the second preset requirement of the subsequent first injection stage, the injection operation is performed according to the preset injection speed first stage value and the preset pouring pressure first stage value; then when the injection time of the subsequent second injection stage reaches the corresponding preset injection time, the second monitoring parameter is controlled to reach the preset injection parameter stage value of the subsequent second injection stage, that is, the second preset requirement of the subsequent second injection stage, and the injection operation is performed according to the preset injection speed second stage value and the preset pouring pressure second stage value, and so on, until all injection stages are completed.

[0075] It should be noted here that: in the injection stage, according to actual control needs, the preset injection speeds in different injection stages are generally different, and the preset pouring pressures in different injection stages can be the same or different.

[0076] In this embodiment, after the injection molding operation is completed, when the third preset requirement of each curing stage is reached, the curing control module 50 performs the curing operation according to the preset holding pressure corresponding to each curing stage. It can be understood that the holding pressure corresponding to the curing stage and the pouring pressure of the injection stage are the same control force in the pouring process, but the pressure definitions at different stages are different.

[0077] In the initial curing stage, when the injection time of the last injection stage reaches the corresponding preset injection time, the third monitoring parameter is controlled to reach the preset initial value of the curing parameter in the initial curing stage, and the curing operation is performed according to the preset initial value of the holding pressure. For example, when the injection time of the last injection stage reaches the corresponding preset injection time, that is, when the injection stage ends, the initial curing stage is entered, and the third monitoring parameter is controlled to reach the preset curing parameter value in the initial curing stage; it can be understood that the temperature of different parts of the mold, the material temperature, the injection nozzle temperature and the temperature of the special area, as well as the mold closing pressure, the pouring pressure and the vacuum degree are controlled to reach the preset initial value of the curing parameter, and when the above-mentioned third monitoring parameter reaches the preset initial value of the curing parameter, that is, the third preset requirement corresponding to the initial curing stage, the curing operation is performed according to the preset initial value of the holding pressure.

[0078] In each subsequent curing stage, when the curing time of the previous curing stage reaches the preset curing time, the third monitoring parameter is controlled to reach the preset curing parameter stage value corresponding to each subsequent curing stage, and the curing operation is performed according to the preset holding pressure stage value corresponding to each subsequent curing stage. For example, when the curing time of the initial curing stage reaches the corresponding preset curing time, the third monitoring parameter is controlled to reach the preset curing parameter initial value of the initial curing stage (control the temperature of different parts of the mold, the material temperature, the injection nozzle temperature and the temperature of the special area, as well as the mold closing pressure, the pouring pressure and the vacuum degree to reach the preset curing parameter stage value), if the third monitoring parameter of the subsequent curing stage reaches the corresponding preset curing parameter stage value, that is, the third preset requirement of the subsequent first curing stage, the curing operation is performed according to the preset holding pressure first stage value; then when the curing time of the subsequent second curing stage reaches the corresponding preset curing time, the third monitoring parameter is controlled to reach the preset curing parameter stage value of the subsequent second curing stage, that is, the third preset requirement of the subsequent second curing stage, and the curing operation is performed according to the preset holding pressure second stage value, and so on, until the curing time of all the last curing stages reaches the preset curing time, and all curing operations are completed.

[0079] The pouring automatic control system in this embodiment is as follows Figure 3 As shown, it also includes a vacuum structure component 60, an injection structure component 70 and a temperature control component 80. The vacuum structure component 60, the injection structure component 70 and the temperature control component 80 respond to the control instructions of the mold opening / closing control module, the vacuum control module, the injection control module and the curing control module, and perform corresponding mold closing operations, vacuuming operations, injection operations, curing operations and mold opening operations according to different preset parameters in the parameter control module.

[0080] In this embodiment, if Figure 4The vacuum structure assembly 60 shown includes a vacuum control valve 61, a vacuum tube 62 and a vacuum pump 63; the vacuum control valve 61 is arranged on the mold 90, the first end of the vacuum tube 62 is connected to the mold 90, and the second end of the vacuum tube 62 is connected to the vacuum pump 63; when the vacuum degree in the mold cavity does not reach the preset vacuum value, the vacuum control valve 61 is controlled to be in the first state and the vacuum pump 63 is operated to adjust the vacuum degree in the mold cavity to reach the preset vacuum value; when the vacuum degree in the mold cavity reaches the preset vacuum value, the vacuum pump 63 is controlled to stop working and the vacuum control valve 61 is in the second state.

[0081] The injection structure assembly 70 in this embodiment includes a compressor (not shown in the figure), a pressure control valve 71, a power pipe 72, a material tank 73, a speed control valve 74, a material delivery pipe 75 and an injection nozzle 76; the first end of the power pipe 72 is connected to the output end of the compressor, and the second end of the power pipe 72 is connected to the input end of the material tank 73; the output end of the material tank 73 is connected to the first end of the material delivery pipe 75, and the second end of the material delivery pipe 75 is connected to the injection nozzle 76 connected to the input end of the mold cavity; the pressure control valve 71 is arranged on the power pipe 72, and is used to control the connectivity state of the power pipe 72; the speed control valve 74 is arranged on the material delivery pipe 75, and is used to control the injection speed in the material delivery pipe 75 to reach the preset injection speed corresponding to each injection stage.

[0082] After entering the injection stage, when the second preset requirement of each injection stage is reached, the injection control module performs the injection operation according to the preset injection speed corresponding to each injection stage. The process of the injection control module performing the injection operation according to the preset injection speed corresponding to each injection stage includes: controlling to open the compressor and controlling the pressure control valve 71, the compressor compresses the air to generate power, and the power outputs the pouring pressure to the material tank 73 through the power pipe 72 under the action of the pressure control valve 71, and the material in the material tank 73 is transferred to the injection nozzle 76 through the material conveying pipe 75 under the driving action of the pouring pressure and injected into the mold cavity. In different injection stages, the opening degree of the speed control valve 74 is adjusted to make the injection speed of the material delivery pipe 75 meet the preset injection speed; and the second monitoring parameter is monitored and adjusted in real time to see whether it meets the second preset requirement; at the same time, the injection time corresponding to each injection stage is recorded, and when the injection time of each injection stage maintains the preset injection time, it directly enters the next injection stage until the material fills the mold cavity; in addition, during the injection process, as the injection pressure in the mold cavity increases, when the pouring pressure does not reach the preset pressure, the opening degree of the control pressure control valve 71 is increased to automatically replenish the pressure, and when the pouring pressure reaches the preset pressure, the control pressure control valve 71 is closed.

[0083] When the material is injected into the mold cavity, the temperature of the mold cavity in contact with the material will begin to drop. The temperature sensor in the corresponding area will sense the temperature drop, and then the temperature control module will heat according to the temperature parameters to achieve the effect of adding heat to the mold.
