[0002] Mold manufacturing plays a vital role in modern industrial production, and the quality of its products directly affects the performance and safety of downstream products.

[0003] However, in traditional mold manufacturing processes, defect detection often relies on manual inspection or a single sensor. This approach suffers from low inspection efficiency, insufficient data accuracy, and the risk of missed detections and misjudgments. Existing single-inspection methods are insufficient to comprehensively acquire information about the mold's surface and interior, making it difficult to accurately identify potential defects. Furthermore, traditional inspection equipment is cumbersome to operate, has a low level of automation, and is complex in structure and difficult to maintain, which to some extent limits the improvement of inspection accuracy and production efficiency.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-3 As shown, this utility model provides a testing device for mold manufacturing, including a main body 1, a lifting plate 2, a lifting column 3, a fixing block 4, and related control units.

[0024] The upper part of the lifting plate 2 is equipped with a coupling agent storage tank 201, which contains a miniature water pump for delivering the coupling agent to the spray nozzle 202. The bottom of the lifting plate 2 is equipped with a distance sensor 204, the spray nozzle 202, and an ultrasonic probe 203. The spray nozzles 202 are arranged in a ring array, and each spray nozzle 202 is connected to the miniature water pump in the storage tank through an independent pipe. The pipe is equipped with a solenoid valve to control the flow rate and range of the sprayed coupling agent.

[0025] The main body of the equipment 1 is equipped with four electrically driven lifting columns 3, which are fixedly installed at the four corners of the lifting plate 2. Each lifting column 3 is equipped with a drive motor, which enables precise lifting and lowering of the lifting plate 2 and ensures a stable gap between the inspection working surface and the workpiece.

[0026] The fixing block 4 is installed at the bottom of each lifting column 3, and its top surface forms the detection working surface. A magnetic attraction component is embedded in the detection working surface. This component includes an iron core 402 and a coil 403, and the magnetic attraction force can be adjusted by adjusting the current of the coil 403. The surface of the magnetic fixing surface 401 is textured with anti-slip material or has a replaceable flexible adsorption layer such as silicone or polyurethane material to enhance the adhesion between the magnetic fixing surface 401 and the workpiece being inspected.

[0027] An infrared beam sensor is installed at the edge of the magnetic fixing surface 401 to detect whether the workpiece completely covers the magnetic area. When the workpiece is not completely covered, the sensor detects an interruption signal, the system triggers an alarm, and automatically prevents the lifting plate 2 from descending, ensuring the safety and reliability of the detection process.

[0028] Furthermore, the spray nozzles 202 are arranged in a ring array and connected to a micro water pump through an independent pipeline. The control logic of the solenoid valve can realize various spraying modes such as pulse spraying and continuous spraying according to the detection requirements, so as to adapt to the requirements of different mold materials and detection environments.

[0029] Furthermore, the array-type ultrasonic probe 203 supports at least three-frequency detection units. Through dynamic configuration of the control system, it can perform targeted detection for different mold structures, thereby improving the sensitivity and accuracy of the detection.

[0030] Specifically, before testing, the workpiece is placed on the testing surface of the fixed block 4. After the magnetic suction assembly is activated, it makes close contact with the workpiece through the magnetic fixing surface 401. At the same time, the infrared beam sensor monitors the coverage of the workpiece to ensure that the workpiece is completely spread in the testing area. After the control system detects that the workpiece is in normal condition, it instructs the micro water pump to start, spraying the coupling agent from the storage tank through an independent pipeline and controlled by a solenoid valve evenly to the spray nozzle 202 at the bottom of the lifting plate 2. The opening time and flow rate of the solenoid valve are dynamically adjusted according to different testing requirements to ensure the best coupling effect of ultrasonic testing.

[0031] The ultrasonic probe 203 at the bottom of the lifting plate 2 is an array probe, containing at least three detection units with different frequencies, covering a frequency range of 1MHz to 15MHz. After the coupling agent is sprayed, the probe emits and receives ultrasonic signals through each detection unit. After amplification and signal processing, the detection signals are dynamically configured by the control system to analyze potential defects inside or on the surface of the workpiece in real time. Simultaneously, a distance sensor 204 installed on the bottom surface of the lifting plate 2 monitors the relative distance between the lifting plate 2 and the workpiece in real time, ensuring that the gap remains within the design requirements during the detection process. If an abnormality occurs in the gap during the detection process, the control system will immediately adjust the electric drive mechanism of the lifting column 3 to ensure detection accuracy and safety.

[0032] After the inspection is completed, the system automatically resets, stops the coupling agent spraying, shuts down the micro water pump, and adjusts the lifting plate 2 back to its initial height. The equipment enters standby mode, ready to accept the inspection task of the next workpiece.

[0033] This invention relates to a testing device for mold manufacturing. It employs a combination of multiple sensors and control methods, achieving high-precision detection of surface and internal defects in mold workpieces. Furthermore, it demonstrates strong practicality and reliability in workpiece fixation, coupling agent spraying, lifting control, and safety protection. The coordinated operation of each module ensures the accuracy of the test data and improves the automation level of the testing process.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
