DETAILED DESCRIPTION

[0027] The following will be combined with the attached Figure 1 -Attached Figure 5 The present invention is further illustrated by the following embodiments.

[0028] Embodiment 1

[0029] This embodiment discloses an automated mold signal detection device.

[0030] Reference Figure 1The automated mold signal detection device is used to detect whether the electrical signal of the electrical signal interaction system of the die-casting mold is transmitted normally. The electrical signal interaction system of the die-casting mold includes electrical components such as detection switches, surface sensors, thermocouples, temperature sensors, and pressure sensors. Among them, the detection switch is used to control the circuit closure of the electrical signal interaction system, the surface sensor is used to detect whether the slider or core puller of the die-casting mold has reached the specified position, the temperature sensor and thermocouple are used to detect the temperature of the key position of the die-casting mold, and the pressure sensor is used to detect the vacuum pressure or casting pressure at the key position of the die-casting mold.

[0031] Reference Figure 2 The automated mold signal detection device is equipped with an electrical signal detection platform, which includes a data acquisition unit 11, a data search unit 12, a judgment unit 13 and an alarm unit 14 connected in sequence. The data acquisition unit 11 is connected to the electrical signal interaction system, and each electrical component of the electrical signal interaction system is configured with a unique identifier. Among them, the data acquisition unit 11 collects data and identifiers of each electrical component in the electrical signal interaction system, the data search unit 12 searches the abnormal data table of the corresponding electrical component according to the identifier, and the judgment unit 13 compares and judges the collected data with the abnormal data table. If the data is in the abnormal data table, the judgment unit 13 judges that the data is abnormal, and the alarm unit 14 alarms after receiving the abnormal signal. In this embodiment, the data acquisition unit 11 collects the current data of each electrical component. In other embodiments, the data acquisition unit 11 can also detect by collecting the voltage data of each electrical. The automated mold signal detection device of the present invention can facilitate the electrical signal detection of the electrical signal interaction system of the die-casting mold, reduce errors and omissions, and realize real-time detection, which is conducive to the automated production of the die-casting mold.

[0032] Reference Figure 3 and Figure 4 The automated mold signal detection device also includes a mounting plate 2, which is inserted into the die-casting mold, and the electrical signal detection platform is mounted on the mounting plate 2, so that the electrical signal detection platform is finally embedded in the die-casting mold. Specifically, the mounting plate 2 is an L-shaped plate, and the mounting plate 2 includes a vertical plate 21 and a horizontal plate 22. The horizontal plate 22 is used to be horizontally inserted into the die-casting mold, and the vertical plate 21 is vertically connected to the top of the outer end of the horizontal plate 22. An installation space is formed between the top surface of the horizontal plate 22 and the inner side surface of the vertical plate 21. The data acquisition unit 11, the data search unit 12, the judgment unit 13 and the alarm unit 14 of the electrical signal detection platform are all mounted on the top surface of the horizontal plate 22 of the mounting plate 2. A power supply 10 is also provided on the horizontal plate 22 of the mounting plate 2, and the power supply 10, the data acquisition unit 11, the data search unit 12, the judgment unit 13 and the alarm unit 14 form a detection circuit.

[0033] If the electrical signal detection platform is powered off, it will cause the electrical signal detection platform to fail, thereby resulting in the inability to detect the electrical signal transmission of the electrical signal interaction system in real time. In order to be able to promptly detect the power outage of the electrical signal detection platform, the present invention further makes the following improvements.

[0034] Reference Figure 3 and Figure 4 , an iron core 31 is mounted on the top surface of the horizontal plate 22 of the mounting plate 2, and part of the circuit of the detection circuit is wound on the iron core 31 to form a coil 32, and the coil 32 and the iron core 31 are combined to form an electromagnet 3, and one end of the electromagnet 3 faces the inner side of the vertical plate 21 of the mounting plate 2. A control rod 4 is horizontally penetrated through the vertical plate 21 of the mounting plate 2, and the control rod 4 is movably arranged on the vertical plate 21 in an inward and outward telescopic manner. The inner end of the control rod 4 is connected to a magnetic metal block 5, and the magnetic metal block 5 is arranged opposite to one end of the electromagnet 3. Furthermore, a spring 6 is connected between the magnetic metal block 5 and the horizontal plate 22 of the mounting plate 2, and the spring 6 makes the magnetic metal block 5 have a tendency to automatically leave the electromagnet 3. Through the above arrangement, when the electric signal detection platform can be powered on smoothly, the magnetic metal block 5 will be adsorbed on one end of the electromagnet 3, so that the outer end of the control rod 4 is shortened. When the electric signal detection platform is powered off, the magnetic metal block 5 will leave the electromagnet 3 under the action of the spring 6, so that the outer end of the control rod 4 is extended. Finally, by observing the state of the outer end of the control rod 4, the staff can timely discover the abnormal power failure of the electric signal detection platform, and avoid the electric signal transmission of the electric signal interaction system cannot be detected in real time. It should be noted that when the magnetic metal block 5 is adsorbed on one end of the electromagnet 3, the magnetic attraction force of the magnetic metal block 5 must be greater than the elastic force of the spring 6, so that the magnetic metal block 5 can be stably adsorbed by the electromagnet 3. Furthermore, in order to facilitate the staff to judge whether the electric signal detection platform is broken, a bright color sticker 41 is attached to the outer end of the control rod 4. When the control rod 4 is shortened inward, the bright color sticker 41 is hidden in the vertical plate 21 of the mounting plate 2. When the control rod 4 is extended outward, the bright color sticker 41 is displayed at the outer end of the control rod 4. At this time, by observing whether the bright color sticker 41 appears, it is possible to observe whether the electric signal detection platform is broken, thereby achieving the effect of convenient observation. In addition, in this embodiment, the magnetic metal block 5 is an iron block.

[0035] Reference Figure 3 and Figure 4, a lamp bead 7 is arranged on the outside of the vertical plate 21 of the mounting plate 2, and the lamp bead 7 is connected with the power supply 10 to form a light-emitting circuit, and the light-emitting circuit is connected in parallel with the detection circuit. The purpose of setting the lamp bead 7 and forming the light-emitting circuit is that when the electric signal detection platform is powered off, further troubleshooting can be conveniently performed by judging the light-emitting condition of the lamp bead 7. If the lamp bead 7 is emitting light at this time, the surface power supply 10 is normal, and if the lamp bead 7 is extinguished at this time, the surface power supply 10 is abnormal, so as to quickly check whether the power failure of the electric signal detection platform is related to the power supply 10. In addition, when the die-casting mold is idle, the electric signal detection platform is usually powered off and idle to protect the data acquisition unit 11, the data search unit 12, the judgment unit 13 and the alarm unit 14. However, if it is idle for a long time, the power supply 10 will not discharge for a long time, thereby causing the natural decay and aging of the electromagnetic internal chemical substances, and finally reducing the effective capacity and life of the power supply 10. At this time, the use of the lamp bead 7 and the light-emitting circuit can ensure that the power supply 10 remains discharged after the electric signal detection platform is powered off, avoiding the above-mentioned adverse consequences.

[0036] Embodiment 2

[0037] This embodiment also discloses an automated mold signal detection device.

[0038] Reference Figure 3 and Figure 5, which is different from the first embodiment in that: a single-pole double-throw switch is provided on the top surface of the horizontal plate 22 of the mounting plate 2, and the single-pole double-throw switch includes an input terminal 8 and two output terminals. In this embodiment, the only input terminal 8 is insulated and connected to the magnetic metal block 5, so that the input terminal 8 can be moved under the active control of the control rod 4 or the passive control of the magnetic metal block 5, and the input terminal 8 is electrically connected to one pole of the power supply 10. The output terminal includes a first output terminal 81 and a second output terminal 82, the first output terminal 81 is electrically connected to the detection circuit, and the second output terminal 82 is electrically connected to the light-emitting circuit. The two output terminals are respectively arranged at the two ends of the moving direction of the input terminal 8, and the first output terminal 81 is located on the inner side, and the second output terminal 82 is located on the outer side. Through the above arrangement, the switch of the detection circuit can be actively controlled by pushing and pulling the control rod 4, thereby controlling the opening and closing of the electric signal detection platform, that is, when the control rod 4 is pushed inward, the input end 8 of the single-pole double-throw switch is connected to the first output end 81, thereby connecting the detection circuit, so that the magnetic metal block 5 is adsorbed on one end of the electromagnet 3, and when the control rod 4 is pulled outward, the input end 8 of the single-pole double-throw switch is connected to the second output end 82, thereby disconnecting the detection circuit and connecting the light-emitting circuit, and finally, the control rod 4 can not only be used by the staff to judge whether the electric signal detection platform is abnormally powered off, but also can be used by the staff to manually actively power off, so as to achieve the effect of making full use of the control rod 4. In addition, this also makes the lamp bead 7 light up only when the electric signal detection platform is powered off, so that the lamp bead 7 is only turned on in the two necessary situations of troubleshooting the power supply 10 and idle discharge, reducing unnecessary lighting states, which is beneficial to extending the service life of the lamp bead 7.

[0039] Reference Figures 3 to 5 Compared with the first embodiment, the second embodiment also has the following different effects. In the first embodiment, even if the die-casting mold causes the magnetic metal block 5 to suddenly separate from the electromagnet 3 due to a large vibration, the magnetic metal block 5 will still be adsorbed on the electromagnet 3 again because the detection circuit is continuously powered on. In the second embodiment, if the die-casting mold causes the magnetic metal block 5 to suddenly separate from the electromagnet 3 due to a large vibration, the input end 8 and the first output end 81 are separated at the same time, so that the detection circuit is powered off, and the magnetic metal block 5 cannot be adsorbed on the electromagnet 3 again, resulting in the abnormal extension of the outer end of the control rod 4, which will force the staff to check this situation. If the cause of the abnormality of the electrical signal detection platform is excluded during the inspection, it can be judged that the die-casting mold has abnormal vibration during the production process, so that the die-casting mold is further inspected to improve the safety production effect of the die-casting mold. In summary, by observing the state of the outer end of the control rod 4, the staff can not only timely discover the abnormal circuit break of the electrical signal detection platform, but also timely discover the abnormal vibration of the die-casting mold after eliminating the abnormal circuit break of the electrical signal detection platform.

[0040] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
