The invention discloses a portable mold hardness measurement device. The portable mold hardness measurement device comprises a hardness gauge body and a measurement device, wherein the measurement device comprises a measurement pipe which is vertically arranged on the side surface of the hardness gauge body and is connected with the hardness gauge body; a hardness display meter is arranged on the front surface of the hardness gauge body; an energy storage spring is arranged inside the measurement pipe; a movable rod connected with the energy storage spring is arranged at one end, extending into the hardness gauge body, of the measurement pipe; a measurement probe is arranged at one end, far from the hardness gauge body, of the measurement pipe; the measurement probe penetrates out of the measurement pipe in a free state of the energy storage spring; the movable rod and the measurement probe are arranged at two ends of the measurement pipe along the center axis of the measurement pipe; the movable rod is arranged in a guide tank of the hardness gauge body. The portable mold hardness measurement device is simple in structure and convenient to use; the hardness and the strength of deep grooves or holes of molds can be detected; the measurement accuracy and the measurement efficiency are improved.
Description
technical field [0001] The invention relates to the technical field of hardness test equipment, in particular to a portable mold hardness measurement device. Background technique [0002] A hardness tester is a testing device used to measure the hardness of a material. Hardness testers are divided into two types: desktop hardness testers and portable hardness testers. The desktop hardness testers are mainly used in laboratories and have the advantages of high precision. The portable hardness testers are used for installed Brinell or permanent assembly parts and are easy to carry. Mainly divided into portable Leeb hardness tester, portable Rockwell hardness tester, portable Brinell hardness tester. [0003] In the actual measurement process, such as when inspecting the mold, if there are grooves or holes on the surface of the mold, due to the heat generated during the drilling or milling process, thermal stress changes will occur in the hole or the groove, so The hardness o...
