Abstract
The utility model discloses a firework powder column compression mould, which comprises an upper substrate, an upper compression column, a powder filling plate provided with a powder filling hole, a lower compression column, a lower substrate and a mould core, wherein the mould core with an upward head is arranged on the top of the lower compression column. By means of the technical scheme, distribution of powder in a lower mould cavity is adjusted when the powder is filled, a powder layer positioned at the head of the mould core is thinner while a powder layer positioned at the tail of the mould core is thicker, each portion of powder bears approximately same force when the compression columns are compressed downwards, so that a formed powder column is even in density of each portion.
Description
Technical field
The utility model relates to a kind of fireworks powder column compacting tool set, especially is provided with the compacting tool set of the fireworks powder column of inner chamber.
Background technology
In the production of display shell, combined firework etc., some gunpowder medicine need adopt hydraulic press to be pressed into the cylindrical grain of hollow, wherein the blast medicine is put in the vacancy, after powder column is lighted and is transmitted in the air, the blast medicine is detonated, the powder column of burning is split into polylith, form the peculiar view that a luminous point becomes a plurality of luminous points on the high-level curtain of night.This series products is referred to as " handle " in the industry usually visually.
The concrete shape of powder column is referring to the example of Fig. 1, the cross sectional shape of its hollow cavity is four sections integral body that identical circular arc is spliced to form outward, splicing place of four arcs, i.e. A point 1, B point 2, C point 3 and D point 4, the powder column wall is thinner, and the explosion time powder column resolves into four along this weak spot.Certainly, the cross sectional shape of powder column hollow cavity also can be square or other can form the shape of similar effect.
The compacting tool set structure of this kind powder column is referring to Fig. 3, the mold of comprise upper substrate 51, go up compression leg 52, core rod 53 being formed, also comprise infrabasal plate 61, be provided with the powder charge plate 64 in powder charge hole 62, the following bed die formed of compression leg 63,62 bottoms, powder charge hole are by following compression leg 63 top seals, core rod 53 afterbodys connect goes up compression leg 52, and core rod 53 heads down.An amount of gunpowder medicine of filling in the powder charge hole 62, the upper substrate 51 that is connected with driving mechanism such as hydraulic press drives compression legs 52, core rod 53 is descending, the gunpowder compression moulding that powder charge hole 62 is interior, horizontal reset on the upper substrate 51 then, core rod 53 is deviate from the moulding powder column.Powder charge plate 64 descending shaped charges in powder charge hole 62 all expose, and collect behind the powder column horizontal reset on the powder charge plate 64, load the gunpowder medicine in the powder charge hole 62 again and suppress once more, successively circulation.
Existing mold defective be, when last compression leg 52 presses down, various piece on the core rod 53 presses down the stop difference, the medicine of device is because the present position difference in the powder charge hole 62, the pressure that medicine bore of different piece differs bigger, is far longer than the medicine at F point 8 places as its pressure that bears of medicine at E point 7 places; Powdered drug is mobile relatively poor simultaneously, causes the each several part density unevenness of shaped charge even, influences firework display effect.
Still not above-mentioned " handle " fireworks powder column, so long as be provided with the fireworks powder column of inner chamber, " meteor " fireworks powder column as shown in Figure 2 is though its mold insert structure difference adopts prior art to suppress and all has above-mentioned drawback.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, a kind of fireworks powder column compacting tool set is provided, and the fireworks powder column each several part density of its compacting is even.In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is, a kind of fireworks powder column compacting tool set, comprise upper substrate, go up compression leg, be provided with the powder charge plate in powder charge hole, following compression leg, infrabasal plate and core rod, it is characterized in that, described core rod device is pressing down the column top, and the head of described core rod up.
Adopt technique scheme, during filling, the gunpowder medicine in described powder charge hole distribution adjusted by core rod, the gunpowder medicine layer that is in the core rod head position is thinner, the gunpowder medicine layer that is in the core rod tail position is thicker, the each several part medicine was stressed roughly the same when last compression leg pressed down, and the each several part density of shaped charge is even.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Fig. 1 is " handle " fireworks powder column structural representation;
Fig. 2 is " meteor " fireworks powder column structural representation;
Fig. 3 is the existing mold structural representation;
Fig. 4 is the utility model specific embodiment structural representation.
The specific embodiment
Referring to Fig. 4, reflect a kind of concrete structure of the present utility model, described fireworks powder column compacting tool set comprises upper substrate 51, last compression leg 52, core rod 53, infrabasal plate 61, following compression leg 63, is provided with the powder charge plate 64 in powder charge hole 62, described core rod 53 devices are descending compression leg 63 tops, be positioned at 62 bottoms, powder charge hole, the head of described core rod 53 up.An amount of gunpowder medicine of filling in the powder charge hole 62, the upper substrate 51 that is connected with driving mechanism such as hydraulic press drive that to go up compression leg 52 descending, the gunpowder compression moulding that powder charge hole 62 is interior, horizontal reset on the upper substrate 51 then.Powder charge plate 64 drives the up certain distance of shaped charge, core rod 53 is deviate from the moulding powder column simultaneously, upper substrate 51 presses down once more then, shaped charge in the powder charge hole 62 is released downwards, horizontal reset on the upper substrate 51 then, collect 64 times horizontal resets of powder charge plate behind the powder column, load the gunpowder medicine in the powder charge hole 62 again and suppress once more, according to this circulation.
As a kind of improvement, described powder charge hole 62 inner chambers are embedded with anti-explosion set 65, can be made of copper material, avoid compression leg 52 and powder charge hole 62 inner chamber frictional impacts to produce spark, cause security incident.As further preferred, described anti-explosion set 65 is outer to be provided with positioning convex ring 66, and positioning convex ring 66 is embedded on 62 internal chamber walls of powder charge hole, prevents the anti-explosion set 65 generation displacement that is hit.
