Abstract
The utility model discloses a kind of injection molds of the gradient sprue bushing of band, including upper die and lower die, the gradient sprue bushing mounted on upper mold, gradient sprue bushing to be embedded into upper mold；Gradient sprue bushing include pedestal, with pedestal is at an angle is obliquely installed the bar portion connecting, the bottom surface of pedestal is opened up there are one arc groove, and bar portion is equipped with a straight slot in an axial direction, which is connected with arc groove；The die cavity for product shaping is offered in lower die.The utility model is simple in structure, reasonable design, is increased without mold base size, and while can effectively ensure that the unloading position bias 20mm of sprue bushing due to the use of the design of gradient sprue bushing using above structure, it is also ensured that the when balance of discharging.
Description
Technical field
The utility model is related to a kind of injection mold, the injection mold of specifically a kind of gradient sprue bushing of band.
Background technology
Sprue bushing is the necessary component in injection mold.Current most injection molds, mostly use normal ranking, i.e. mold
Sprue bushing in tool wants eccentric 20mm or so, and to coordinate with sprue bushing, so mold base needs are processed, this is again so that after increasing
Mold base and the injection molding machine of bigger specification coordinate, and just increase the cost of injection molding quickly.Further, since sprue bushing is eccentric,
Because of balance when eccentric and mould ejection when causing mould ejection.
Utility model content
The purpose of the utility model is to overcome deficiencies of the prior art, provide a kind of note of the gradient sprue bushing of band
Mould.
To achieve the above object, technical solution used by the utility model is：A kind of injection mould of the gradient sprue bushing of band
Tool, including upper die and lower die, the gradient sprue bushing mounted on upper mold, gradient sprue bushing are embedded into upper mold；Gradient sprue bushing include pedestal,
With pedestal is at an angle is obliquely installed the bar portion connecting, the bottom surface of pedestal is opened up there are one arc groove, and bar portion is equipped with one in an axial direction
Straight slot, the straight slot are connected with arc groove；The die cavity for product shaping is offered in lower die；The front end of the bar portion of gradient sprue bushing
It is connected with die cavity, is molded so that flowable materials can enter in die cavity through gradient sprue bushing.The utility model is simple in structure, if
Meter is reasonable, and mold base size is increased without while can effectively ensure that the unloading position bias 20mm of sprue bushing using above structure,
And due to the use of the design of gradient sprue bushing, it is also ensured that the when balance of discharging.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model, and abstract figure.
Specific implementation mode
For convenience of being further understood to the utility model, embodiment is enumerated in conjunction with attached drawing, the utility model is made
Further instruction.
Embodiment：
As shown in Figure 1, the utility model includes upper mold 1, lower die 2, the gradient sprue bushing 3 mounted on upper mold 1, gradient sprue bushing is embedding
In 3 embedment upper molds；Gradient sprue bushing 3 include pedestal, with pedestal is at an angle is obliquely installed the bar portion connecting, the bottom surface of pedestal opens up
There are one arc groove, bar portion is equipped with a straight slot in an axial direction, which is connected with arc groove；It is offered for product in lower die 2
The die cavity of forming；The front end of the bar portion of gradient sprue bushing 3 is connected with die cavity, so that flowable materials can be into through gradient sprue bushing 3
Enter in die cavity and is molded.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, any person skilled in the art is changed or is modified to possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation, but it is all without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model
To any simple modification, equivalent change and modification made by above example, the model of technical solutions of the utility model is still fallen within
In enclosing.
