Abstract
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
The present invention relates to a kind of hot runner structure, in particular, relate to the valve swing mechanism on a kind of hot flow path.
Background technology
In the prior art, hot runner structure in use, need that a valve is installed to be exhausted, the exhaust apparatus of current hot runner structure is installed on above hot flow path, in application process, due to the thermodynamic activity of mould, the exhaust apparatus of top is heated, cause oil temperature to heat and affect the normal use of exhaust apparatus, and thickening due to mould, adding material cost; The technological deficiency of the structure existence of current mold hot flow, becomes the technical problem that those skilled in the art are anxious to be resolved.
Summary of the invention
Technical purpose of the present invention overcomes hot runner valve door in prior art to also exist and easily heated and add mold thickness, add the technical problem of mold materials cost; Thering is provided one to be located at flow distribution plate side, normal use can not be affected by heating in use, and mold thickness can be made thinner, more save the valve swing mechanism of the mold hot flow of mold materials.
For realizing above technical purpose, technical scheme of the present invention is
The valve swing mechanism of mold hot flow, include a hot runner valve, described hot runner valve is connected with one end of lever, the other end of lever is connected with the driving shaft of hydraulic jack, described lever is connected with a fulcrum, described fulcrum be located on lever seat, lever seat is located on hydraulic jack shell.
Further, heat insulating mattress is provided with between described lever seat and hydraulic jack shell.
Further, described is located on the fulcrum draw-in groove on lever seat, equidistantly on described lever seat is provided with some fulcrum draw-in grooves, and fulcrum slides on the fulcrum chute of lever, is provided with firm screw between described fulcrum and lever.
Further, the other end of described lever seat is located on die shunting plate, is provided with heat insulating mattress between described lever seat and die shunting plate.
In an application of the invention, lever seat one end is located on hydraulic jack shell, the other end of lever seat is located on die shunting plate, hot flow path is provided with in die shunting plate, hot flow path outlet is provided with hot runner valve, by the heat insulating mattress between lever seat and hydraulic jack shell and the heat insulating mattress between lever seat and die shunting plate, the heat that the heat on die shunting plate is delivered on hydraulic jack is few, can not have influence on the normal use of hydraulic jack; Hydraulic jack is by hydraulic principle, and activation lever moves up and down, and forms opening or closing of hot runner valve, be exhausted at the other end of lever; Because lever seat is provided with multiple fulcrum draw-in groove, fulcrum can need to regulate fulcrum to be positioned at fulcrum on lever seat according to the stroke of hot runner valve, fulcrum chute on lever is free to slide fulcrum, the holding screw above chute when fulcrum slides into required position, by tight for fulcrum because of on lever.Exhaust velocity is determined according to the Lift of hot runner valve, and hot runner valve is opened higher, and exhaust velocity is faster, otherwise then exhaust velocity is slower.
Advantageous Effects of the present invention is: by the design of lever, and heat trnasfer reduces, and hydraulic jack can normally work, and lever is the side at mould, saves the material cost of mould, adjustable exhaust velocity; Those skilled in the art can not obtain the technology enlightenment adopting lever from prior art, the technology enlightenment that the valve stroke of fulcrum draw-in groove adjustment (adjusting) lever one end is set at lever can not be obtained from lever principle, thus technological improvement of the present invention for a person skilled in the art, there is unobviousness, compared with prior art, there is the technological improvement of outstanding substantive distinguishing features and remarkable technological progress.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's specific embodiment.
Detailed description of the invention
Composition graphs 1, describes the specific embodiment of the present invention in detail, but is not limited in any way claim.
In the structure of the valve swing mechanism of mold hot flow, include a hot runner valve, described hot runner valve is connected with one end of lever 100, the other end of lever 100 is connected with the driving shaft of hydraulic jack 101, described lever 100 is connected with a fulcrum 102, described fulcrum 102 be located on lever seat 200, lever seat 200 is located on hydraulic jack 101 shell.Heat insulating mattress is provided with between described lever seat 200 and hydraulic jack 101 shell.In force, fulcrum 102 is located on the fulcrum draw-in groove on lever seat 200, equidistantly on lever seat 200 is provided with some fulcrum draw-in grooves, and fulcrum 102 slides on the fulcrum chute of lever 100, is provided with firm screw between described fulcrum 102 and lever 100.The other end of lever seat 200 is located on die shunting plate, is provided with heat insulating mattress between lever seat 200 and die shunting plate.
In an application of the invention, lever seat 200 one end is located on hydraulic jack 101 shell, the other end of lever seat 200 is located on die shunting plate, hot flow path is provided with in die shunting plate, hot flow path outlet is provided with hot runner valve, by the heat insulating mattress between lever seat 200 and hydraulic jack shell and the heat insulating mattress between lever seat 200 and die shunting plate, the heat that the heat on die shunting plate is delivered on hydraulic jack 101 is few, can not have influence on the normal use of hydraulic jack 101; Hydraulic jack 101 is by hydraulic principle, and activation lever 100 moves up and down, and forms opening or closing of hot runner valve, be exhausted at the other end of lever 100; Because lever seat 200 is provided with multiple fulcrum draw-in groove, fulcrum 102 can need to regulate fulcrum 102 to be positioned at fulcrum on lever seat 200 according to the stroke of hot runner valve, fulcrum 102 is free to slide the fulcrum chute on lever 100, holding screw above fulcrum chute when fulcrum 102 slides into required position, by tight for fulcrum 102 because of on lever 100.Exhaust velocity is determined according to the Lift of hot runner valve, and hot runner valve is opened higher, and exhaust velocity is faster, otherwise then exhaust velocity is slower.
In a word, the material cost saving mould of the present invention, adjustable exhaust velocity; There is unobviousness, compared with prior art, there is the technological improvement of outstanding substantive distinguishing features and remarkable technological progress.
