[0049] Please refer to Figure 1. This embodiment provides an intelligent production system 100 for core shooting machines, which realizes digital control and thus realizes automated production of core shooting machines, reduces process operation time, improves production efficiency, and reduces production costs.

[0050] The core-shooting machine intelligent production system 100 provided in this embodiment includes a core box identification module 110, a lower computer 130, a PLC control module 150 and an upper computer 170. The core box identification module 110 is used to identify the core box; the lower computer 130 is used to perform lower-level operation actions on the core box according to the initial production parameters and the revised production parameters; the PLC control module 150 is communicated with the core box identification module 110 and the lower computer 130, and is used to collect the actual production parameters of the core box; the upper computer 170 is communicated with the PLC control module 150, and is used to set the initial production parameters and set the revised production parameters according to the actual production parameters; wherein, the PLC control module 150 is also used to transmit the initial production parameters and the revised production parameters to the lower computer 130.

[0051] In this embodiment, the upper computer 170 is a central control computer, which plays a decision-making role, and the lower computer 130 is an actuator, which can be various actuator components in the core shooting machine, such as a heating device, a sandblasting device, and a mold clamping device. This embodiment realizes the automatic operation of the core shooting machine through data control, and uses data judgment to automatically switch the mold loading-production-unloading process, shortening the operation time and thus improving production efficiency.

[0052] In this embodiment, the lower-level operation includes a preheating operation. The initial production parameters include the core box's preheating and curing time, preheating temperature, and preheating times. The upper computer 170 is used to set the core box's curing time, preheating temperature, and preheating times, and issues a preheating end instruction after the preheating times are reached. Specifically, during preheating, the upper computer 170 can set the initial preheating and curing time, preheating temperature, and preheating times, which are then executed by the lower computer 130, thereby preheating the core box. Furthermore, during the preheating process, the PLC control module 150 can collect actual production parameters from the lower computer 130 and the core box, further optimize them, and generate corrected production parameters, which are then transmitted back to the lower computer 130 by the PLC control module 150 to implement feedback control.

[0053] In this embodiment, the lower-level operation can also include a pre-production operation. The initial production parameters include the first curing time, first curing agent dosage, and pre-production times for the core box. The upper computer 170 is used to set the first curing time, first curing agent dosage, and pre-production times for the core box, and issue a pre-production end instruction after the pre-production times are reached. Specifically, after preheating, the pre-production operation can be performed. The initial first curing time, first curing agent dosage, and pre-production times can be set by the upper computer 170 and executed by the lower computer 130, thereby completing the pre-production operation for the core box and performing preliminary core production. In addition, during the pre-production process, the actual production parameters of the lower computer 130 and the core box can be collected and further optimized accordingly by the PLC control module 150. After generating the corrected production parameters, the PLC control module 150 transmits them to the lower computer 130 again to achieve feedback control.

[0054] In this embodiment, the lower-level operation can also include normal production operations. The initial production parameters include the second curing time, second curing agent dosage, and production quantity of the core box. The upper computer 170 is used to set the second curing time, second curing agent dosage, and production quantity of the core box, and issue a production end instruction after the production quantity is reached. Specifically, after pre-production, normal production operations can be performed. The initial second curing time, second curing agent dosage, and production quantity can be set by the upper computer 170 and executed by the lower computer 130, thereby achieving normal production operations for the core box and thus normal core making. In addition, during normal production, the actual production parameters of the lower computer 130 and the core box can be collected by the PLC control module 150, and further optimized accordingly. After generating corrected production parameters, the PLC control module 150 transmits them to the lower computer 130 again to achieve feedback control.

[0055] It should be noted that the purpose of pre-production here is to conduct trial production and evaluate the product, and then enter the normal production process after rationalization and improvement.

[0056] In this embodiment, the core box identification module 110 includes a radio frequency identification unit and a core box communication unit. The radio frequency identification unit is communicatively connected to the core box communication unit, which is in turn communicatively connected to the PLC control module 150. The core box is provided with a radio frequency tag, and the radio frequency identification unit is used to identify the radio frequency tag. Specifically, the radio frequency tag on the core box is an RFID tag. The radio frequency identification unit can contact the RFID tag using a camera or a code scanning sensing device to complete the core box identification.

[0057] It is worth noting that the recognition of the core box here is mainly to identify the corresponding core box on the production line to ensure that the core box is consistent with the subsequent lower-level operation actions.

[0058] In this embodiment, the PLC control module 150 includes a data collection unit and a control unit. The data collection unit is in communication with the slave computer 130 and is used to collect actual production parameters of the core box. The control unit is in communication with the slave computer 130 and the host computer 170 and is used to transmit initial production parameters and revised production parameters to the slave computer 130. Specifically, the data collection unit can collect data using various sensors installed on the slave computer 130 or the core box, and the control unit can obtain relevant actual production parameters from the host computer 170 and apply them to the slave computer 130.

[0059] 2 , an embodiment of the present invention further provides a core-shooting machine intelligent production method, which is applicable to the aforementioned core-shooting machine intelligent production system 100. The method includes the following steps:

[0060] S1: Identify the core box.

[0061] Specifically, the core box identification module 110 may identify the mark on the core box, thereby comparing it with the core box on the core shooter. If the comparison is successful, the subsequent step S2 is performed; if the comparison is unsuccessful, the operator is notified to replace it.

[0062] S2: Perform lower-level operation on the core box with initial production parameters.

[0063] Specifically, the initial production parameters are set by the upper computer 170 , and then the lower computer 130 performs lower-level operation actions on the core box.

[0064] S3: Obtain actual production parameters of the core box.

[0065] Specifically, the actual production parameters of the core box can be obtained through the PLC control module 150, and specifically, the actual production parameters can be collected through the data collection unit of the PLC control module 150, wherein the data collection unit can collect data through various sensors set on the lower computer 130 or the core box, and transmit the data to the upper computer 170. The control unit of the PLC control module 150 can obtain the relevant parameters set by the upper computer 170 and apply them to the lower computer 130.

[0066] S4: Modify the production parameters according to the actual production parameter settings.

[0067] Specifically, the upper computer 170 will first set the initial production parameters and execute them through the PLC control module 150 and the lower computer 130. Then, the actual production parameters will be obtained through the PLC control module 150, and the corrected production parameters will be obtained after calculation and optimization based on the actual production parameters. They will also be executed through the PLC control module 150 and the lower computer 130.

[0068] S5: End of production.

[0069] Specifically, when executing steps S2 to S5, when performing lower-level operation actions, a preheating action can be performed first, first obtaining the preheating and curing time, preheating temperature and preheating times of the core box set by the upper computer 170; then preheating the core box according to the preheating and curing time, preheating temperature and preheating times; finally, a preheating end instruction is issued after the preheating times are reached.

[0070] After the preheating action is completed, the pre-production action can be performed. First, the first curing time, the first curing dosage and the number of pre-production times of the core box set by the upper computer 170 are obtained; then the pre-production action is performed on the core box according to the first curing time, the first curing dosage and the number of pre-production times; finally, the pre-production end instruction is issued after the number of pre-production times is reached.

[0071] After the pre-production action is completed, normal production action can be carried out. First, the second curing time, second curing dosage and production quantity of the core box are obtained; then, normal production action is performed on the core box based on the second curing time, second curing dosage and production quantity; and after the production quantity is reached, the production end instruction is issued; finally, the supply of auxiliary materials is stopped.

[0072] In summary, the core shooting machine intelligent production system 100 and method provided in this embodiment uses the core box identification module 110 to identify the core box, and uses the lower computer 130 to perform lower-level operation actions based on the core box. The PLC control module 150 is simultaneously connected to the core box identification module 110 and the lower computer 130, and can collect the actual production parameters of the core box. The upper computer 170 can communicate with the PLC control module 150 and can set initial production parameters and set and modify production parameters based on actual production parameters. The PLC control module 150 is also used to transmit the output production parameters and modify production parameters to the lower computer 130. Since the setting and transmission of production parameters are both automatic, digital control is achieved. Compared with the prior art, the core shooting machine intelligent production system 100 and method provided in the embodiment of the present invention uses the PLC control module 150 to collect and transmit data parameters, and the upper computer 170 to set parameters, achieving digital control, thereby realizing automated production of the core shooting machine, reducing process operation time, improving production efficiency, and reducing production costs.
