Specific embodiment
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific embodiment with reference to attached drawing.
Referring to figs. 1 to Fig. 3.
The utility model embodiment discloses a kind of inclined ejector pin mechanism, including oblique top 1, preceding mould 2, rear mold 3, top plate 4, preceding mould
Through the oriented slot 6 for passing through and being slidably matched for oblique top 1 of setting on the cavity 5 that is formed between 2 and rear mold 3, rear mold 3,
One end of oblique top 1 is hinged with top plate 4, and the other end of oblique top 1 offsets across oriented slot 6 with cavity 5, runs through setting in oblique top 1
Ejector pin component 7 is equipped with, ejector pin component 7 includes the thimble 71 with boss, elastic component 72, jacking block 73, and jacking block 73 is provided with inclination side
To the inclined outside faces 731 identical with 1 glide direction of oblique top, the boss both ends of thimble 71 are respectively with jacking block 73 far from inclined outer side
731 one end of face and 72 one end of elastic component abut, and are provided with recess on 73 contact surface of jacking block on oriented slot 6 and hang down with thimble 71
0 ° of straight face 61,71 both ends of thimble offset respectively with 0 ° of face 61 and cavity 5.
By the articulated connection of 1 bottom of oblique top on the top plate 4, by toward applying thrust on top plate 4, since oblique top 1 is led with inclination
It being slidably matched to slot 6, oblique top 1 is slided along oriented slot 6, in 1 sliding process of oblique top, drives thimble 71 by 0 ° of face 61,
After thimble 71 skids off 0 ° of face 61, the contact of incline plane of thimble 71 and oriented slot 6, since thimble 71 is by the bullet of elastic component 72
Power acts on, at this time thimble 71 by oriented slot 6 reaction force, wherein driving oblique top 1 upward containing a upward component
Continue to slide along oriented slot 6, until after thimble 71 resets under the active force of elastic component 72, oblique top 1 stops sliding, and pushes away
Dynamic process is completed.
In order to which oblique top 1 is allowed smoothly to skid off and can reset, 0 ° of face, 61 top is located at based on above-described embodiment, in rear mold 3 and is set
Be equipped with fillet surface 31, fillet surface 31 and the distance between the intersecting lens that horizontal plane is formed and oriented slot 6 are c, thimble 71 and
The distance between the contact point and oriented slot 6 in 0 ° of face 61 are b, b ＜ c；It is located at 31 top of fillet surface in rear mold 3 to be provided with again
Position inclined-plane 32,1 glide direction angle with horizontal plane of oblique top are α °, and reset 32 angle with horizontal plane of inclined-plane is+2 ° of ＞ α °.It is pushing up
After needle 71 is by 0 ° of face 61, thimble 71 continues to be connected on 6 inclined-plane of oriented slot under being acted on by 72 elastic force of elastic component to be slided,
When thimble 71 slides into fillet surface 31, oblique top 1 can be turned round along fillet surface 31 so that oblique top 1 can be more greatly
Plastic is ejected, plastic ejection process is completed at this time.Will reset 32 angle with horizontal plane of inclined-plane be set to than 1 glide direction of oblique top with
This differential seat angle can be set as 5 ° by big 2 ° of horizontal plane angle or more, and after the turn of oblique top 1, oblique top 1 can obtain more activities
Space enters oriented slot 6 so as to oblique top 1 under the pulling force of top plate 4, and then oblique top 1 is restored to and inclines under 4 pulling force of top plate
Glide direction that oblique guide groove 6 matches simultaneously finally resets.
In order to enhance the fluency that thimble 71 slides, based on above-described embodiment, thimble 71 contacts one end with 0 ° of face 61 as half
Sphere.Hemispheroidal needle point enhances the fluency that thimble 71 slides on 6 surface of oriented slot, and prevent thimble 71 with
The card of fillet surface 31, which relates to, to be obstructed.
In order to ensure stability that ejector pin component 7 slides together with oblique top 1, based on above-described embodiment, jacking block 73 and oblique top 1
It is fixed by screws.Jacking block 73 is fixedly connected in oblique top 1 by screw, avoid in 7 taxiing procedures of ejector pin component with
The collision of oriented slot 6 generates interference, prevents damage thimble 71.
Based on above-described embodiment, elastic component 72 is spring.Selecting spring, can simplify structure can simultaneously provide as elastic component 72
One reliable and stable elastic force is to thimble 71.
Above example only expresses a kind of embodiment of the utility model, and description is more specific and detailed, but not
Can the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill people for this field
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With novel protection domain.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
