Description

Oil pipe joint structure of integrative die-casting injection chamber Technical Field The utility model relates to the technical field of die-casting oil pipes, in particular to an oil pipe joint structure of an integrated die-casting injection chamber. Background In the practical application of the integral die casting technology, the injection chamber is used as a core component, the performance of the oil pipe joint is directly related to the running stability and the production efficiency of equipment, and along with the development of the integral die casting technology to large-scale and precise, higher requirements are put forward on the functions of sealing, filtering, visual monitoring and the like of the oil pipe joint. The common oil pipe joint in the market at present has a plurality of defects in structural design, firstly, a sealing structure adopts a single sealing ring or a simple gasket, sealing is realized only by means of static extrusion, and under the working conditions of high-frequency impact load and severe vibration of an injection chamber, the sealing ring is easy to loosen and deform, so that hydraulic oil leaks, resource waste is caused, equipment failure is possibly caused due to unstable pressure of a hydraulic system, and shutdown maintenance cost is increased; Secondly, the existing oil pipe joint is generally lack of visual observation design, so that workers are difficult to intuitively grasp the real-time flow state and flow change of hydraulic oil, and when the problems of abnormal pressure, fluctuation of flow speed and the like occur in a hydraulic system, failure points cannot be quickly positioned, so that failure detection efficiency is low, and production continuity is seriously affected; In addition, in the working process of the die casting machine, a large amount of impurities such as metal scraps, oxides and the like can be generated by factors such as die abrasion, high-temperature oxidation and the like, the impurities are very easy to enter a hydraulic system through an oil pipe joint, a filtering device is not arranged in the traditional oil pipe joint, abrasion of precise components such as a hydraulic pump and a valve bank can be accelerated by hydraulic oil mixed with the impurities, system pressure loss and control precision are reduced, equipment paralysis is even caused, the service life of the equipment is greatly shortened, and maintenance cost and production safety hidden danger are increased.
