Abstract

The utility model discloses spraying decoration and a manufacturing mould thereof; the spraying decoration comprises an outer cylinder, an igniter, effect medicine, an upper mud plug and a muddy bottom; the upper end of the outer cylinder is provided with the upper mud plug; an inner cylinder is arranged below the upper mud plug; the lower end of the outer cylinder is sealed by a bottom plug; an effect medicine layer is arranged in the inner cylinder, with the lower end open and the lower end sealed by the bottom plug; the middle hole of the upper mud plug is a trumpet shape with small upper part and large lower part. In the spraying decoration made by the technical proposal, a burning chamber is arranged between the upper mud plug and the effect medicine layer; the effect medicine is fully burned in the cylinder; meanwhile, the trumpet shape of the middle hole of the upper mud plug also greatly reduces the resistance to the spraying of the effect medicine. The utility model provides a spraying decoration product without dreg dropping at all for the market.

Description

A kind of spraying decoration and mfg. moulding die thereof

Technical field

The utility model relates to spraying decoration class fireworks field, is a kind of internal structure of spraying decoration class fireworks specifically.

Background technology

Spraying decoration class fireworks are a kind of traditional firework products, and the structure of traditional product is referring to Fig. 1, establish at the bottom of the last bod 1 in hole and the mud 5 by cylindrical tube 3, lead-in wire 2, effect medicine layer 4, centre and form.It makes flow process: cylindrical shell 3 is inverted is inserted in mould, build the bod 1 earlier, build effect medicine layer 4 on the last bod 1, then at the bottom of building mud on the effect medicine layer 45.Owing to tamp layer by layer between mud layer and the effect medicine layer, lack the structure of similar combustion chamber, part effect medicine can not fully burn in tube; The corner angle of going up simultaneously the bod 4 mesopores 6 lower port have sprayed inhibition to the effect medicine.There is the defective of falling slag easily in the spraying decoration product of this structure, promptly just lands at the effect of combustion medicine on a small quantity, causes potential safety hazard easily, particularly at stage, when the contour shunting yard in hotel is seted off, fall slag and may cause bigger infringement and cause claiming damages.

Summary of the invention

In order to address the above problem, a kind of spraying decoration product that does not fall the slag phenomenon fully is provided, the technical scheme that the utility model is taked is, a kind of spraying decoration, comprise urceolus, igniter, effect medicine, go up at the bottom of the bod, the mud, it is characterized in that: the bod has been built in described urceolus upper end, and the last bod is arranged with inner core, and the urceolus lower end is with bottom plug one shutoff; Build effect medicine layer in the described inner core, the upper end is open, and the lower end is with bottom plug two shutoff; Described upward bod mesopore is up-small and down-big horn shape.Described bottom plug can be materials such as shale or papery.

Adopt the spraying decoration of such scheme, constituted a combustion chamber between the last bod and effect medicine layer, the effect medicine is fully burning in tube; The horn shape of going up simultaneously bod mesopore has also reduced inhibition that the effect medicine is sprayed greatly.

As a kind of embodiment of the present utility model, described igniter adopts the lead-in wire igniting, and the mesopore of going up the bod certainly causes effect medicine layer.

As another kind of embodiment of the present utility model, described igniter adopts electric duration and degree of heating igniting, for fear of the lead of electric duration and degree of heating the injection of effect medicine is produced inhibition, lead can not introduced from last bod mesopore, optimal way be its lead from bottom plug one insertion, between inside and outside cylindrical shell, cause effect medicine layer.Certainly, also there is multiple known distortion in the introducing mode of lead, as from cylindrical shell side perforate introducing etc., does not repeat them here.

As a kind of optimal way of the present utility model, the described maximum open diameter of going up bod mesopore lower port equals the internal diameter of inner core.

According to the traditional fabrication mode, realize that the chamber structure in the tube is extremely difficult.The utility model adopts the design of inner core, be the convenience in order to make, its making flow process is: mould shown in Figure 4 is inserted the cylindrical shell appropriate location build the bod, build in inner core into the effect medicine and with bottom plug two shutoff, the urceolus of then inner core being packed into is with bottom plug one capping urceolus bottom nozzle.

Mould shown in Figure 4 aims at making spraying decoration product of the present utility model and designs, in order to adapt to the up-small and down-big horn shape of bod mesopore.Described mould head also is up-small and down-big horn shape.

Below in conjunction with the drawings and specific embodiments the utility model is introduced.

Description of drawings

Fig. 1 is an existing product vertical section structure schematic diagram;

Fig. 2 is embodiment one a vertical section structure schematic diagram;

Fig. 3 is embodiment two vertical section structure schematic diagrames;

Fig. 4 is a mould vertical section structure schematic diagram.

The specific embodiment

Referring to Fig. 2, the bod 12 has been built in urceolus 13 upper ends of described spraying decoration, and the last bod 12 is arranged with inner core 14, and urceolus 13 lower port are with bottom plug one 17 shutoff; Build effect medicine layer 15 in the inner core 14, the upper end is open, and the lower end is with bottom plug 2 16 shutoff; The described upward bod 12 mesopores 18 lower port are up-small and down-big horn shapes, and its vertical section is " eight " font; Igniter adopts lead-in wire 11 igniting, and the mesopore 18 of going up the bod 12 certainly causes effect medicine layer 15.

Referring to Fig. 3, different with such scheme is, igniter adopts electric duration and degree of heating 19 igniting in this scheme, and its lead 20 inserts from bottom plug 1, causes effect medicine layer 15 between inner core 14, outer cylinder body 13.

The vertical section of mould is made up of base 31, die body 32, mould head 33 as shown in Figure 4, and mould head 33 is up-small and down-big horn shapes, and its vertical section is " eight " font.Its size and material depend on the needs.

The above, only be embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model to any simple modification that above embodiment did, be equal to and replace and modify, all fall in the scope of technical solutions of the utility model.

Claims
