Adjustable mould clamping force detection device capable of continuously monitoring

Abstract

The invention discloses an adjustable mould clamping force detection device capable of continuously monitoring. A deep hole for accommodating a force measuring rod is arranged along an axial direction of a tie bar; the force measuring rod is of a reducing structure and comprises a large-diameter section and a small-diameter section; the big-diameter section is arranged in the deep hole; the small-diameter section is sleeved with a spring; a fixed seat is mounted on the tie bar; the small-diameter section passes through a through hole of the fixed seat and protrudes out of the through hole; one end of the spring is pressed against the inner lateral surface of the fixed seat, and the other end of the spring is pressed against a step of the force measuring rod; a mould clamping force sensor is mounted on the fixed seat by a fixing pipe clamp; the sensing end of the mould clamping force sensor is in close contact with the end part of the force measuring rod. In the pressurization process, a generated expansion force (back pressure) enables the tie bar to generate a certain deformation so as to push the force measuring rod to generate displacement, and then data is read by the mould clamping force sensor; after a mould is opened, the pressure is reduced, and the force measuring rod is reset by the spring; the size of a mould clamping force and a stress condition of the tie bar each time are well monitored so as to prevent insufficiency / overload of the mould clamping force or breakage of the tie bar is prevented.

Description

technical field [0001] The invention relates to a continuously monitoring and adjustable clamping force detection device. Background technique [0002] With the rapid development of the national economy, especially the development of the automobile industry and 3C industry, the demand for large-scale die-casting machines has increased. For example, the current die-casting machines are mainly composed of machine bases, molding mechanisms, injection mechanisms, and hydraulic control systems. , electrical control system, lubrication system, cooling and protective door mechanism, there are multiple Corinthian pillars on the fitting mechanism, but the connection and fixing method of the existing Corinthian pillars is fixed on the frame by four bolts , It is fixed by bolts, it is inconvenient to adjust the pressure when locking, and it is not easy to find the joint pressure point of the bolts, which makes the adjustment difficult. [0003] When choosing a die-casting machine, you...
