Technical field
The utility model relates to a kind of injection mold.
Background technology
During design injection mold, if when master mold has barb, also accordingly there is barb the same with male model, need to have two ejector retainner plates to coordinate oblique top to take off barb.The principle of this structure is: in the time of the die sinking of male and female die, master mold needle plate due to excellent power collagen because of, start to move down, in master mold, oblique top also moves thereupon simultaneously, until barb is wherein also provided with the guide pillar that runs through upper bolster, stripper plate, upper ejector retainner plate, lower ejector retainner plate and caster, guide pillar is responsible for the needle plate that leads, prevent oblique top offset, card breaks.
This type of solves barb mode need to, at the inner two boards that increases of template, go up ejector retainner plate and lower ejector retainner plate, so corresponding mould bases just needs increasing, waste material and resource.
Utility model content
The utility model is intended at least solve one of technical problem existing in prior art.
For addressing the above problem, the utility model proposes a kind of injection mold, comprising: caster and male model plate; Mother module core and male die core, described mother module core is located at the below of described caster, and described male die core is located at the below of described mother module core, and described male model plate is positioned at the below of described mother module core, forms the die cavity for the treatment of injecting products between mother module core and male die core; And oblique top, the upper end of described oblique top is provided with top platform, and the lower end of oblique top is tiltedly passed down through described mother module core and matches with master mold barb position; Cavity, described cavity is positioned at the below of described top platform; Spring, described spring is positioned at the upper end of oblique top, and oblique top is applied to downward pressure; Reset pin, described reset pin upper end connects described top platform, and down sliding is through described mother module core, and its lower end is concordant with the lower surface of mother module core when matched moulds.
According to injection mold of the present utility model, when the matched moulds, the lower end of reset pin is moved by using of male die core, upwards withstands the top platform of oblique top, in oblique top, moves, and the lower end of oblique top arrives product barb position.Injection moulding is complete, and during die sinking, oblique top is owing to there being spring to apply downward elastic force to oblique top below, and oblique top moves down, and sets stroke according to barb size, i.e. the height of cavity, thereby barb.With respect to adding at mould the structure of ejector retainner plate and lower ejector retainner plate in prior art, the utlity model has easy for installation, processing is simple, master mold barb mode is ingenious, demand space is little, the feature cutting the waste.
In addition, according to injection mold of the present utility model, also there is following additional technical feature:
Preferably, the upper end of described oblique top and the upper surface of described mother module core are concordant.
Preferably, described spring is positioned at spring groove, and described spring groove is located at the inside, upper end of oblique top, the upper end open of spring groove.
Preferably, described spring fitting direction is consistent with the oblique direction of oblique top.
Additional aspect of the present utility model and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present utility model.
