Description

Technical Field

[0001] The utility model relates to the technical field of bottom plug installation quality detection, in particular to a vacuum casting mold bottom plug installation quality detection device. Background Art

[0002] Currently, molds used in vacuum induction furnace castings come in sets of 48, 36, or 20 molds. These are secured by closely packed steel tubes, without any other fixtures between the tubes. Therefore, after all tubes are in place, it is necessary to inspect the gaps between the tubes and the bottom plug (such as those caused by rust, bumps and dents on the interface between the tubes and the bottom plug, hard impurities, or other compression). Gaps can cause molten alloy to leak through these gaps during casting, resulting in incomplete or completely empty mold tubes. In severe cases, leaking mold tubes earlier in the casting sequence can prevent subsequent mold tubes from being fully filled, severely impacting casting yield. The current conventional inspection method involves probing the steel tube with a light source, illuminating the gap between the bottom plug and the tube, and determining the presence of a gap based on the halo pattern. However, conventional light sources are unsuitable for detecting gaps between vacuum casting molds, exhibit poor detection results, are inconvenient to use, and have low durability, making them unsuitable for inspecting the installation quality of the gap between the vacuum casting mold and the bottom plug.

[0027] The detection method and principle of the vacuum casting mold bottom plug installation quality detection device are as follows:

[0028] After the vacuum casting mold bottom plug and mold tube are installed in the mold frame, the vacuum casting mold bottom plug installation quality inspection device is bent according to the different mold tube length specifications to make it suitable for the corresponding specifications; then, the light source mechanism of the vacuum casting mold bottom plug installation quality inspection device is downward and inserted into the gap between the two mold tubes until the transparent protective cover at the end of the top light source touches the bottom plug surface and the side light source is level with the bottom end of the mold tube; turn on the side light source, move the device, fine-tune the position of the side light source, and horizontally illuminate each position of the joint between the bottom plug and the bottom end of the mold tube. The detection diagram is shown as follows Figure 2 (a) Observe the inside of the mold tube. If light leakage can be observed inside the mold tube (such as Figure 3 ), indicating that the gap between the bottom plug and the mold tube is large and the installation is not in place, then the vacuum casting mold bottom plug installation quality inspection device is adsorbed to the nearby steel pipe by the magnetic suction part, freeing up both hands to adjust the mold tube, and reinstall or replace the bottom plug and mold tube; if no light leakage can be observed inside the mold tube, it means that the right-angle bottom plug and the mold tube are well connected and can be used for vacuum casting; in addition, for the situation where the gap between the two mold tubes is inconvenient to observe, the light source mechanism of the vacuum casting mold bottom plug installation quality inspection device is downward and probed into the inner diameter of the mold tube to be inspected until the transparent protective cover at the end of the top light source touches the surface of the bottom plug; turn on the top light source to illuminate each position of the joint between the bottom plug and the bottom end of the mold tube, as shown in the detection diagram. Figure 2As shown in (b); observe the outside of the mold tube. If a halo can be observed outside the mold tube, it means that the gap between the bottom plug and the mold tube is large and the installation is not in place. Then, the vacuum casting mold bottom plug installation quality inspection device is adsorbed to the nearby steel pipe through the magnetic suction part, freeing up both hands to adjust the mold tube, and reinstall or replace the bottom plug and mold tube. If no halo can be observed outside the mold tube, it means that the right-angle bottom plug is well connected to the mold tube and can be used for vacuum casting.
