Description

Technical Field

[0001] The utility model relates to the field of mold detection, in particular to a mold detection device. Background Art

[0002] Moulds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the material being formed. It is known as the "mother of industry".

[0003] In the prior art, there is a method of testing the sealing of a mold by injecting water into the mold. For example, Chinese patent publication number CN218674089U discloses a mold production inspection tool. This solution transports water between the movable mold and the fixed mold through a connecting pipe, fills the space between the fixed mold and the movable mold with water, and observes whether there is water seepage at the connection between the movable mold and the fixed mold. If water seeps out, it indicates that the mold is unqualified. If no water seeps out, the mold is qualified. This solution requires continuous observation of the mold, and the detection time is long. After the mold is tested, the water inside needs to be cleaned before the next set of tests can be carried out, which is inconvenient. Utility Model Content

[0031] A plurality of rotating handles are fixedly connected to the nut 6 in the circumferential direction. The plurality of rotating handles facilitates the rotation of the nut 6.

[0032] The fixing member 3 includes a horizontal plate 31 and auxiliary plates 32 distributed on both sides of the horizontal plate 31.
