Abstract
The utility model discloses a kind of optimization structure of compression molding combined firework shortening forming time, some launch holes are uniformly distributed on combined firework body, launch hole bottom sets flash hole, the side of the combined firework body is distributed some grooves, groove is along the axially arranged of launch hole, groove is arranged on fireworks this body sidewall between two launch holes, and groove runs through the side wall of fireworks body.Using the compression molding combined firework of above-mentioned technical proposal, its compression molding, the time of drying can shorten to 300 seconds or so, relative to existing product shortening forming time 1/3rd, substantially increase production efficiency；The structural strength of product can effectively ensure that the transmitting of fireworks uses simultaneously；It is convenient in demoulding；And the phenomenon for having prevented partial carbonization and side chip occurs.
Description
Technical field
It the utility model is related to a kind of amusement pyrotechnics product, especially a kind of combined firework.
Background technology
Compression molding combined firework is the combined firework that a kind of slurry is molded by molding, drying mode overall time.
Possession face fireworks display class firework product, is commonly called as potted flower.The shape and structure of its formed body are similar with conventional combination fireworks, formed body
The overall appearance shape of body is mainly four prisms cylinder, also there is hexagonal prism or cylinder etc..If main is uniformly distributed on body
Shape cavity, the effect of tubular housing is similar with the transmitting outer barrel of conventional combination fireworks, launching fireworks medicine built in launch hole and
Effect part is, it is necessary to which that bears pyrotechnic composition fires pressure, it is necessary to higher structural strength, commonly referred to as launch hole；Launch hole bottom
End sets flash hole.Flash hole is used to connect the lead positioned at fireworks bottom surface.
The major drawbacks of present compression molding combined firework are that the daily output of present fireworks enterprise is substantially all
It is to be calculated with million hairs, and slurry compression molding drying time is longer now, at least needs 480 seconds, influences production efficiency；Fireworks
After body global formation is dried, easily there is carbonization phenomenon in subregion, and this body side surface of fireworks is easily cracking (to be referred to as in the industry
For chip) phenomenon, it have impact on product quality.
Utility model content
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is to provide a kind of group of compression molding
The structural improvement of fireworks is closed, the formed product time can be shortened on the basis of product structure intensity is ensured.It is above-mentioned in order to solve
Technical problem, the technical solution adopted in the utility model are a kind of optimization knots of compression molding combined firework shortening forming time
Structure, some launch holes are uniformly distributed on the combined firework body, and launch hole bottom sets flash hole, it is characterised in that described
The side of combined firework body is distributed some grooves, groove along the axially arranged of launch hole, groove be arranged at two launch holes it
Between fireworks this body sidewalls on, groove runs through the side wall of fireworks body.
The beneficial effects of the utility model are that, using the compression molding combined firework of above-mentioned technical proposal, it is molded into
Type, the time of drying can shorten to 300 seconds or so, relative to existing product shortening forming time 1/3rd, greatly improve
Production efficiency；The structural strength of product can effectively ensure that the transmitting of fireworks uses simultaneously；It is convenient in demoulding；And office is prevented
Portion is carbonized and the phenomenon of side chip occurs.
Preferably, the groove is arranged at the center between two launch holes.Improve the uniformity of product configurations.
Preferably, the spacing of the groove and launch hole is not less than the pitch of holes between each launch hole.Improve product configurations
The uniformity, ensure structural strength.
Preferably, the base angle of the groove is fillet.Ensure the structural strength of launch hole.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the overall structure diagram of compression molding combined firework；
Fig. 2 is the mplifying structure schematic diagram of part A shown in Fig. 1.
Embodiment
Referring to accompanying drawing, some launch holes 1 are uniformly distributed on the compression molding combined firework body, the bottom of launch hole 1 is set
Flash hole is put, each side of the combined firework body is distributed eight grooves 2, and groove 2 is axially arranged along launch hole 1, recessed
Groove 2 is arranged on fireworks this body sidewall between two launch holes 1, and groove 2 runs through the side wall of fireworks body.The groove 2 is set
The center being placed between two launch holes 1.The spacing H of the groove 2 and launch hole 1 is not less than between each launch hole 1
Pitch of holes L.The base angle 201 of the groove 2 is fillet.
Above-mentioned implementation is merely to clearly illustrate the utility model, and it is not intended that to the utility model
Make any restrictions.The utility model has known a variety of replacements or deformation in the art, is not departing from this practicality
On the premise of new essential meaning, the scope of protection of the utility model is each fallen within.
