Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for this
For the those of ordinary skill of field, without creative efforts, others are can also be obtained according to these attached drawings
Attached drawing.Wherein：
Fig. 1 is the structural schematic diagram before the penetration type crowded teeth mold of the present invention squeezes；
Fig. 2 is the structural schematic diagram after the penetration type crowded teeth mold of the present invention squeezes；
Fig. 3 is that going out for the present invention and goes out the installation diagram of charge bar pressing plate at charge bar.
Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1 to Figure 3, in a specific embodiment, penetration type crowded teeth mold provided by the invention includes one kind
Penetration type crowded teeth mold comprising：The annular punch 3 being connected on upper die holder；Activity is threaded through the core in the annular punch 3
Stick punch 2；Elastomeric element 1 between the core rod punches 2 and the upper die holder, the elastomeric element 1 is in pressure direction
On can occur elastic deformation, after the ends of the core rod punches 2 is oppressed, top will oppress the elastomeric element 1 with
Make 1 elastic shrinkage of the elastomeric element, after the compressing disappearance of the end of core rod punches 2, the elastomeric element 1 restores original length
Degree, the shrinkage degree of the elastomeric element 1 is bigger, and the size that the core rod punches 2 expose the annular punch 3 is shorter；Connection
Cavity plate 3 on lower die holder is formed with the die cavity to match with the tooth form forging 100 in the cavity plate 3；Positioned at the die cavity
Lower section and with the discharging chamber 10 of die cavity perforation connection, be equipped in the discharging chamber 10 coaxial with the core rod punches 2
What is be arranged goes out charge bar 5, it is described go out charge bar 5 lower end be detachably connected on the lower die holder, it is described go out charge bar 5 upper end and institute
The end for stating core rod punches 2 is inconsistent, it is described go out charge bar 5 outer diameter be less than the tooth form forging 100 endoporus aperture.
Using the penetration type crowded teeth mold of the present invention, tooth form forging 100 can be inserted in automatically after being extruded it is described go out
On charge bar 5, after going out on charge bar 5 the tooth form forging 100 for covering full extrusion molding, charge bar 5 can be easily removed out, and will squeeze
The tooth form forging 100 of forming is placed in transport box.The penetration type crowded teeth mold of the present invention, can effectively prevent tooth form forging 100 to exist
It is bruised during discharging, reduces the scrappage of tooth form product in process of production.
When the elastomeric element 1 keeps original length, the core rod punches 2 expose it is described state annular punch 3, when described
When the shrinkage degree of elastomeric element 1 reaches maximum, the core rod punches 2 are fully retracted into the inside of the annular punch 3.It is above-mentioned
Setting so that tooth form forging 100 can be easily transferred to from core rod punches 2 after being extruded it is described go out charge bar 5 on.
Refer to Fig. 3, it is described go out charge bar 5 lower end be arranged with it is jaggy go out charge bar pressing plate 6, the size of the notch
More than it is described go out charge bar 5 outer diameter.Based on the notch, it is described go out charge bar 5 can easily install to lower die holder and from lower die
It is removed on seat.
It is described go out charge bar pressing plate 6 upper surface be covered with rubber layer 7, the tooth form forging 100 can be effectively prevent to fall
It is bruised in falling.
In the present embodiment, the elastomeric element 1 is polyurethane elastomer, and the rubber layer 7 is polyurethane rubber layer.
In the present embodiment, the upper end position for going out charge bar 5 on the inner wall of the discharging chamber 10 described in is equipped with inductive probe
8, the inductive probe 8 is electrically connected with the control system of the extrusion die.When it is described go out charge bar 5 upper end position at there are teeth
When shape Forging 100, the inductive probe 8 generates inductive signal and sends the signal to the control system of penetration type crowded teeth mold,
Control system disconnects the travel switch of upper die holder, and upper die holder can not continue to push.
It is equipped with reclaiming plate 9 at the upper end opening of the discharging chamber 10, opens reclaiming plate 9, charge bar can be easily removed out
5。
The operation principle of penetration type crowded teeth mold in the present embodiment is as follows：
Original state, elastomeric element 1 keep original length, the lower end of annular punch 3 to be located in the die cavity of cavity plate 4, plug
Punch 2 and the upper-end contact for going out charge bar 5,
Upper die holder moves up, and annular punch 3 leaves the die cavity of cavity plate 4, and core rod punches 2 are separated with charge bar 5 is gone out, and at this time will
Tooth form forging 100 to be extruded is placed in the die cavity of cavity plate 4.
Upper die holder moves down, and annular punch 3 and core rod punches 2 move downward simultaneously, and core rod punches 2 pass through tooth form forging
100 endoporus and with it is described go out charge bar 5 upper-end contact, annular punch 3 contacts with the tooth form forging 100.At this point, this implementation
The penetration type crowded teeth mould of example shows configuration state as shown in Fig. 1.
Upper die holder continues to be pressed down against, and annular punch 3 starts to squeeze tooth form forging 100 to complete to the tooth form forging
100 extrusion molding.Meanwhile elastomeric element 1 generates elastic shrinkage under the extruding of core rod punches 2, core rod punches 2 are relative to ring
Shape punch 3 moves upwards.Attached drawing 2 is referred to, when the shrinkage degree of elastomeric element 1 reaches maximum value, the core rod punches 2 are complete
Portion is retracted to inside the annular punch 3, and the tooth form forging 100 of extrusion molding completely disengages core rod punches 2 and is nested into discharging
On stick 5.Outer diameter due to going out charge bar 5 is less than the aperture of the endoporus of tooth form forging 100, under the effect of gravity, 100 edge of tooth form forging
Go out charge bar 5 described in fall downwards.Due to going out on charge bar pressing plate 6 to be covered with the rubber layer 7 of polyurethane material, tooth form forging can be reduced
The shock of a fall of part 100 prevents tooth form forging 100 to be bruised.
It after the extrusion molding for completing current tooth form forging 100, repeats the above steps, carries out next tooth form forging 100
Extrusion molding.When going out set completely tooth form forging 100 on charge bar 5, that is to say, that the upper end position for going out charge bar 5 is also cased with tooth form forging
When part 100, the inductive probe 8 being arranged on the inner wall of the discharging chamber 10 generates inductive signal and inductive signal is sent to institute
The control system of penetration type crowded teeth mold is stated, control system disconnects the travel switch of upper die holder, and upper die holder can not push.
At this point, the reclaiming plate 9 at the upper end opening of the discharging chamber 10 is opened, by the tooth form forging of the full extrusion molding of set
100 go out the taking-up of charge bar 5, change it is new go out charge bar 5, control system reconnects the travel switch of upper die holder, upper die holder starts
The extruding flow of next round.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in fields
Personnel are it should be understood that the description in embodiment is only exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change should all belong to the scope of protection of the present invention.Scope of the present invention is by the power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
