The invention discloses a digital display-type mold hardness measuring device. The measuring device comprises a measuring tube vertically arranged on the side surface of a mainframe and connected with the mainframe, wherein a digital display screen is arranged on the mainframe; a hardness sensor is arranged in the mainframe and connected with the digital display screen through a first A / D conversion circuit; an energy storage spring is arranged in the measuring tube; the hardness sensor connected with the energy storage spring is arranged at the end, extending into the mainframe, of the measuring tube; a measuring probe is arranged in the end, away from the mainframe, of the measuring tube and penetrates out of the measuring tube when the energy storage spring is in a free state; a guide groove coaxial with the energy storage spring is formed in the mainframe; the hardness sensor is fixed in the guide groove; the measuring probe is propped against a groove / hole to be tested to drive the energy storage spring to upwardly extrude the hardness sensor. The digital display-type mold hardness measuring device is simple in structure and convenient to use, and not only meets the requirement for measuring the hardness and the strength of the deep groove / hole of a mold but also improves the measuring accuracy and the measuring efficiency.
Description
technical field [0001] The invention relates to the technical field of hardness test equipment, in particular to a digital display 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 har...
