技术领域Technical field

各种型材和制件在热挤压生产过程中，模具的工作环境非常恶劣，除了要承受较大的负荷以及坯料与模壁的接触应力之外，还要受到交变温度的影响。所以，生产过程中，不仅要考虑模具的润滑，也必须充分考虑模具的冷却。目前生产过程中，是在挤压机间歇期间，多是由人工手动分别向左右模腔内喷洒石墨乳，进行冷却和润滑。该方法操作不便，而且每次取放喷头过程干扰较大，效率太低；而且由石墨乳的特性决定了喷头会出现喷射不顺或堵塞的情况。During the hot extrusion production process of various profiles and parts, the working environment of the mold is very harsh. In addition to bearing a large load and the contact stress between the blank and the die wall, it is also affected by alternating temperatures. Therefore, during the production process, not only the lubrication of the mold must be considered, but also the cooling of the mold must be fully considered. In the current production process, during the intermittent period of the extruder, graphite emulsion is usually manually sprayed into the left and right mold cavities for cooling and lubrication.

It is easy to retract and retract without affecting the processing work; the lifting and lowering of the nozzle 1 is controlled by the cylinder, the position is accurate, and it can comprehensively and without omissions To lubricate and cool the mold, the setting of the stirring blade 21 can play a disturbing role to avoid the deposition of graphite emulsion on the side wall of the inner casing 13. The setting of the dredging structure can prevent the nozzle 1 from being moved by pressing the front end of the inner casing 13. It is clogged after being left unused for a long time or after coarse particles appear in the graphite emulsion.
除说明书所述技术特征外，均为本专业技术人员已知技术。Except for the technical features described in the manual, all are technologies known to those skilled in the art.
