Abstract
The utility model provides a positioning guide post structure of a die. The structure ensures precision fit of a guide post and a guide sleeve, and is simple, low in machining difficulty and machining precision and low in machining cost. The positioning guide post structure comprises a front template, a rear template, the guide post and the guide sleeve, wherein the guide sleeve is positioned in a through hole of the front template, and the guide post passes through a through hole of the rear template. The positioning guide post structure is characterized in that: the part of the guide post positioned in the front template comprises a lower upward closed cone frustum part and an upper cylindrical part; the inner hole of the guide sleeve comprises an upper circular through hole and a lower downward expanded part; and the inner edge face of the guide sleeve is tightly attached to the outer edge face of the part of the guide post extending into the front template.
Description
Technical field
The utility model relates to the technical field of structures of injection mold, is specially a kind of positioning guide column structure of mould.
Background technology
The accurate location of front mould, back mould is to be difficult to the perfect a difficult problem that solves in the precision die structural design always.The precision-fit that particularly between front template, the rear pattern plate is the guide pillars and bushes on the pattern frame positions; Guiding.Because guide pillars and bushes is the accurate matched in clearance that belongs to less, monolateral about 0.01 ~ 0.02 gap is unallowable for precision die.So we are by every means preceding; The gap between mould upper guide post guide pin bushing is eliminated by the various auxiliary fine positioning of design mechanism on the die joint of back mould, but this type of designs often complex structure, and structure is more complicated, and difficulty of processing and machining accuracy are also just high more, the processing cost height.
Summary of the invention
To the problems referred to above, the utility model provides a kind of positioning guide column structure of mould, and it guarantees the precision-fit of guide pillar, guide pin bushing, and simple in structure, difficulty of processing and machining accuracy is low, processing cost is little.
A kind of positioning guide column structure of mould; Its technical scheme is such: it comprises front template, rear pattern plate, guide pillar, guide pin bushing; Said guide pin bushing is positioned at the through hole of said front template; Said guide pillar runs through the through hole of said rear pattern plate; It is characterized in that: said guide pillar is positioned at the inner part of said front template and comprises bottom upwards close up frustum of a cone part, top column part, and the endoporus of said guide pin bushing comprises top round tube hole, the downward flared part in bottom, and the inner edge surface of said guide pin bushing fits tightly the outer edge surface that said guide pillar stretches into the inner part of said front template.
It is further characterized in that: the outer edge surface that said guide pillar stretches into the inner part of said front template has oil guide groove.
After adopting the said structure of the utility model; Cooperating of taper seat on guide pillar paniculidine bit position and the guide pin bushing, fit clearance is zero, reaches the locating effect of accurate zero clearance; It guarantees the precision-fit of guide pillar, guide pin bushing, and simple in structure, difficulty of processing and machining accuracy is low, processing cost is little.
Description of drawings
Fig. 1 is the front view structural representation of the utility model.
The specific embodiment
See Fig. 1; It comprises front template 1, rear pattern plate 2, guide pillar 3, guide pin bushing 4; Guide pin bushing 4 is positioned at the through hole 5 of front template; Guide pillar 3 runs through the through hole 6 of rear pattern plate 2, and guide pillar 3 is positioned at the inner part of front template 1 and comprises bottom upwards close up frustum of a cone part 7, top column part 8, and the endoporus of guide pin bushing 4 comprises top round tube hole 9, the downward flared part 10 in bottom; The inner edge surface of guide pin bushing 4 fits tightly the outer edge surface that guide pillar 3 stretches into the part of front template 1 inside, and the outer edge surface that guide pillar 3 stretches into the part of front template 1 inside has oil guide groove 11.
