The invention discloses a valve swinging mechanism for a die hot runner, and technically aims to provide the valve swinging mechanism for the die hot runner, wherein the valve swinging mechanism is arranged on one side of a flow distribution plate, normal application cannot be influenced when the valve swinging mechanism is heated during the using process, the thickness of a die can be thinner, and more material for the die can be saved. The valve swinging mechanism comprises a hot runner valve, wherein the hot runner valve is connected with one end of a lever; the other end of the lever is connected with a driving shaft of a hydraulic cylinder; the lever is connected with a pivot; the pivot is arranged on a lever seat; and the lever seat is arranged on an outer housing of the hydraulic cylinder. The valve swinging mechanism reduces the heat transmission, the hydraulic cylinder can operate normally, the material cost of the die is saved, and the exhaust velocity can be adjusted; in addition, the valve swinging mechanism is suitable for being applied in the hot runner technology.
Description
technical field [0001] The invention relates to a hot runner structure, more specifically, to a valve swing mechanism on the hot runner. Background technique [0002] In the prior art, during the use of the hot runner structure, a valve needs to be installed for exhausting. The exhaust device of the current hot runner structure is installed above the hot runner. During the application process, due to the thermal effect of the mold , heating the exhaust device above, causing the oil temperature to heat and affecting the normal use of the exhaust device, and due to the thickening of the mold, the material cost is increased; the technical defects in the current structure of the hot runner of the mold have become urgent for those skilled in the art. technical issues to be resolved. Contents of the invention [0003] The technical purpose of the present invention is to overcome the technical problems that the hot runner valve structure in the prior art is easy to be heated, in...
