Description
Technical field
The present invention relates to a kind of fireworks paper tube molding die, especially a kind of paper tube band self-styled concave bottom molding die of lead.
Background technique
In fireworks production, several procedures are that soil or the scraps of paper is first used to seal paper tube one end as paper tube bottom, are then inserted
Enter lead, then just can enter next procedure after solid flashing composition is dry with solid flashing composition anchor leg.It is cumbersome, it is time-consuming and laborious,
Production efficiency is low, and product quality is difficult to ensure.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of paper tube band self-styled concave bottom molding dies of lead.
The present invention adopts the following technical scheme that.
A kind of paper tube band self-styled concave bottom molding die of lead, have the self-styled sunken bottom external mold of band lead, self-styled concave bottom external mold and from
Seal concave bottom internal model:
The self-styled sunken bottom external mold of band lead has an inner hole, at least 2 forming blocks on inner hole wall, forming blocks have front, at
Type face and back, each forming surface be at one on the surfaces of revolution in the crest curve of female coaxial, a line of front and
The a line of forming surface is overlapped, and the another a line of subsequent a line and forming surface is overlapped, and the another a line of above and below exists
On inner hole wall, there is a centre bore on the top of the surfaces of revolution in crest curve；
The self-styled concave bottom external mold has an inner hole, and there is a boss in inner hole bottom surface, and there is a circular hole in the end face of boss, boss
At least 2 assistant formation blocks, assistant formation block have preceding secondary surface and rear secondary surface, preceding auxiliary between side and inner hole inner peripheral surface
The intersection of face and rear secondary surface is assistant formation rib；
The self-styled concave bottom internal model has traveller, and traveller is inserted in the hole of outer bar, and the elongated slot sold across outer bar periphery is fixed on cunning
In column, there is a pressure spring between the bottom surface in the hole of outer bar and the inner end of traveller, there is a flange on outer bar periphery.
The surfaces of revolution is internal conical surface in the crest curve.
The assistant formation rib has arc section or straightway.
It is simple and reliable that compared with the prior art, the advantages of the present invention are as follows mould structures, disposably just produces paper tube band
The self-styled concave bottom of lead, simplifies process, substantially increases production efficiency, ensure that product quality.

Specific embodiment
Below in conjunction with drawings and examples, present invention is further described in detail.
As shown in Fig. 1-6, a kind of paper tube band self-styled concave bottom molding die of lead has the self-styled cone bottom external mold of band lead, self-styled
Concave bottom external mold and self-styled concave bottom internal model:
The self-styled cone bottom external mold of band lead has an inner hole 5, there is 4 forming blocks on 5 wall of inner hole, and forming blocks have front 1, molding
Face 3 and below 4, each forming surface 3 be at one on the internal conical surface of female coaxial, before 1 a line and forming surface 3
A line be overlapped, behind 4 a line and forming surface 3 another a line be overlapped, before 1 and below 4 another a line including
On 5 wall of hole, there is a centre bore 2 on internal conical surface top.
The self-styled concave bottom external mold has an inner hole 8, and there is a boss 7 in 8 bottom surface of inner hole, and the end face of boss 7 is plane, convex
There is a circular hole 6 in the end face of platform 7, there is 3 assistant formation blocks, assistant formation block between the side of boss 7 and the inner peripheral surface of inner hole 8
There are preceding secondary surface 9 and a rear secondary surface 10, the intersection of preceding secondary surface 9 and rear secondary surface 10 is assistant formation rib 11, assistant formation rib
11 be circular arc.
The self-styled concave bottom internal model has traveller 18, and traveller 18 is inserted in the hole of outer bar 13, and pin 16 passes through 13 periphery of outer bar
Elongated slot 15 be fixed in traveller 18, have a pressure spring 14,13 circumference of outer bar between the bottom hole of outer bar 13 and the inner end of traveller 18
There is a flange 12 on face.
Paper tube works in this way with the self-styled concave bottom molding die of lead: drawing first as shown in fig. 7, lead 20 is inserted into band
In the centre bore 2 of the self-styled cone bottom external mold of line, the band self-styled cone bottom outer die casing of lead with lead is opened at fixed both ends
One end of the paper tube cylinder 19 of mouth, and rotary squeezing is carried out to cylinder 19, make original a part of cylinder to a direction of rotation
Deformable folding becomes the cone bottom 21 with lead, and it is solid to squeeze lead 20 to a direction of rotation deformable folding by the paper at cone bottom 21
It is fixed.Self-styled concave bottom internal model is inserted in the paper tube with lead cone bottom 21 again, the cone bottom 21 with lead is revolved with self-styled concave bottom external mold
Turn to be squeezed into the concave bottom 22(with lead as shown in Fig. 8).
