Description
Technical field
It the utility model is related to the improved structure in extrusion die field, specifically die head runner.
Background technology
Extrusion flat-mould head used now, conventional is rack-style manifold structure, as shown in figure 1, the knot in the prior art
The die head tightening platform matched moulds screw 6 of structure is arranged situation, middle matched moulds screw 6 apart from die lip discharging opening farther out, two side matched moulds
Screw 6 is nearer apart from die lip discharging opening, and such a structure causes the torque of middle and two side matched moulds screws 6 locking upper/lower die not
Equally, die lip lip spreading phenomenon easily occurs, and then is unfavorable for sealing, it is also difficult to produces the higher product of thickness requirement.
Utility model content
The purpose of this utility model is that the torque for being directed to screw lock upper/lower die in the prior art is different, easily hair
The situation of raw die lip lip spreading, there is provided the improved structure of die head runner, it is ensured that die head matched moulds flat seal.
The utility model is that solve above-mentioned technical problem by following technical proposals：The improved structure of die head runner,
Characterized in that, it includes upper die body 1 and lower mold body 2, the upper die body 1 is fixed by some matched moulds screws 6 and lower mold body 2 to be connected
Connect, the middle part that the matched moulds screw 6 is through to lower mold body 2 by the upper surface of upper die body 1 is set, the upper die body 1 and lower mold body 2
Between form triangular facet gap 3, the opening in the triangular facet gap 3 gradually subtracts from the front portion of upper die body 1 and lower mold body 2 to rear portion
Small, the rear end in the triangular facet gap 3 is provided with some screw tightening platforms 4, the size and triangular facet of the screw tightening platform 4
The size of the rear end of gap 3 is consistent, and screw mounting hole 5 is provided with the center of the screw tightening platform 4, and part matched moulds screw 6 passes through
The screw mounting hole 5 is worn to set.
Further, the triangular facet gap 3 is provided with manifold runner 7, and the manifold runner 7 is in the front end of triangular facet gap 3
Center be provided with tunnel inlets 8.
Further, the manifold runner 7 is rack-style structure, two die body 1 and lower moulds on the side of the manifold runner 7
The rear portion extension of body 2.
Further, the cross sectional shape up and down of the screw tightening platform 4 is circular or ellipse.
Positive effect of the present utility model is：, can be with using the improved structure of die head runner of the present utility model
So that the distance of die body tightening platform matched moulds screw is more nearly die lip discharging opening, obtain above and below middle and two side screw locks
The torque of mould is the same, to ensure die lip middle lip not spreading, can so obtain the uniform melt of flowing, it is ensured that product
Thickness quality.

Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but reality of the present utility model
The mode of applying is not limited only to this.
The utility model aims to provide the improved structure of die head runner, it is characterised in that it includes upper die body 1 and lower mold body
2, the upper die body 1 is fixedly connected by some matched moulds screws 6 with lower mold body 2, fastening structure, and the matched moulds screw 6 is by upper mould
The middle part that the upper surface of body 1 is through to lower mold body 2 is set, and triangular facet gap 3, institute are formed between the upper die body 1 and lower mold body 2
The opening for stating triangular facet gap 3 is gradually reduced from the front portion of upper die body 1 and lower mold body 2 to rear portion, behind the triangular facet gap 3
End is provided with some screw tightening platforms 4, and the size of the screw tightening platform 4 is consistent with the size of the rear end of triangular facet gap 3, institute
State and screw mounting hole 5 is provided with the center of screw tightening platform 4, part matched moulds screw 6 is set through the screw mounting hole 5.
When it is implemented, the triangular facet gap 3 is provided with manifold runner 7, the manifold runner 7 is before triangular facet gap 3
The center at end is provided with tunnel inlets 8.
When it is implemented, the manifold runner 7 is rack-style structure, the manifold runner 7 two on the side die body 1 and under
The rear portion extension of die body 2, rack-style structure is smaller compared to T-type structure branch pipe, and melt is shorter in the entrance residence time, avoids material
It is rotten；It is larger compared to the fish tail structure angle of flare, long die body is not had.
When it is implemented, the cross sectional shape up and down of the screw tightening platform 4 is circular or ellipse, it is easy to attachment screw
Shape.
When it is implemented, die head is made up of upper die body 1 and lower mold body 2, the end of triangular facet gap 3 between upper and lower die body 1,2
Screw tightening platform 4 is set, and the size of screw tightening platform 4 is consistent with the size of triangular facet gap tail end, screw tightening platform 4
Center at be provided with screw mounting hole 5, can cause the matched moulds screw 6 in tightening platform distance be more nearly die lip discharging
Mouthful, solve the matched moulds screw 6 of centre apart from die lip discharging opening farther out, the matched moulds screws 6 of two sides apart from die lip discharging opening compared with
The problem of near, the final middle torque that upper/lower die is locked with the matched moulds screw 6 of both sides is the same, to ensure interlabium in die lip
Mouth not spreading, it is achieved in that the uniform melt of flowing, it is ensured that product thickness quality.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
