Description

The bright pearl fixed die of technology display shell

Technical field

The utility model relates to a kind of fixed die, particularly relates to a kind of fixed die that is used for fixing the bright pearl in the technology display shell.

Background technology

In display shell, in order to reach desirable firework display effect, between the shell case of display shell and unpacking propellant, be provided with the bright pearl of technology, the bright pearl of technology requires need to be fixed on certain location between the shell case of display shell and the unpacking propellant as figure, font etc. according to firework display effect, like this, the technology bullet is aloft seted off after bag is opened in emission and is produced as effects such as figure, fonts.But, the display shell of this structure, the position of the bright pearl of technology bullet is difficult to control in manufacture process, it is long to shoot the time, and production efficiency is low, and the bright pearl of technology bullet is in case dislocation, just do not reach desirable firework display effect, and display shell is in handling process, and the bright pearl that produces in the technology bullet owing to collision, vibration is shifted, and makes the not good or unfruitful phenomenon of product firework display effect.

The utility model content

Technical problem to be solved in the utility model provides and a kind ofly can be installed in the bright pearl of technology bullet in the display shell quickly and easily and the bright pearl fixed die of the technology display shell that can keep bright pearl can not be shifted in display shell.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: be provided with the bright pearl installing hole of technology bullet by the firework display effect design on bowl-shape die body.

Adopt the bright pearl fixed die of technology display shell of technique scheme, be provided with the required bright pearl installing hole of technology bullet at bowl-shape die body by the firework display effect requirement, when making display shell, two bowl-shape die bodys are buckled into an orbicule relatively envelope unpacking propellant, only need the technology bullet is pressed in the bright pearl installing hole of technology bullet on the bowl-shape die body just gently, improved manufacturing production efficiency, the bright integument of technology bullet is fixed in the bright pearl installing hole of technology bullet, in handling process, can not guarantee firework display effect because of collision, vibration produce the bright pearl displacement of technology bullet.The utility model can adopt the original foaming manufacturing of polyphenyl foamed plastic to form, and is with low cost.

In sum, the utility model is a kind ofly can be installed in the bright pearl of technology bullet in the display shell quickly and easily, can keep bright pearl can not be shifted in display shell and the bright pearl fixed die of technology display shell simple in structure, easily manufactured, with low cost, that performance is feasible.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that the utility model uses schematic diagram.

The specific embodiment

Referring to Fig. 1, on the bowl-shape die body 1 that original foaming manufacturing forms with the polyphenyl foamed plastic, be provided with the bright pearl installing hole 2 of technology bullet by the firework display effect design.

Referring to Fig. 1 and Fig. 2, when making display shell, two bowl-shape die bodys 1 are buckled into an orbicule relatively envelope unpacking propellant 5, only need the bright pearl 4 of technology bullet is pressed in the bright pearl installing hole 2 of technology bullet on the bowl-shape die body 1 just gently, improved manufacturing production efficiency, be provided with shell case 3 and propellant powder 7 and fuse cord 6 at bowl-shape die body 1 skin, the bright pearl 4 of technology bullet is fixed in the bright pearl installing hole 2 of technology bullet, in handling process, can not guarantee firework display effect because of collision, vibration produce the bright pearl displacement of technology bullet.

When setting off, propellant powder 7 is overhead with shell case 3 and unpacking propellant 5,1 emission of bowl-shape die body, fuse cord 6 unpacking propellant 5 that ignites aloft, and the bright pearl 4 of technology bullet is penetrated in unpacking propellant 5 blasts, the bright pearl 4 of technology bullet is aloft seted off by the figure or the font of designing requirement, produces bright and colourful firework display effect.

Claims (1)

1. The bright pearl fixed die of a kind of technology display shell is characterized in that: be provided with the bright pearl installing hole of technology bullet (2) by the firework display effect design on bowl-shape die body (1).
