Firework launching device, and manufacturing method and die thereof

Abstract

The invention discloses a firework launching device, and a manufacturing method and a die thereof. The device has the advantages that the use of the device is safer and more environment-friendly, the structure is simple and reasonable, and the manufacturing technology is simple. The firework launching device comprises launching cylinders each of which is provided with a plurality of launching holes, and corresponding bases thereof, wherein lead grooves and gunpowder concave parts are formed in the bases, the lead grooves and the gunpowder concave parts correspond to the launching holes of the launching cylinders, and separating hole plates each of which is provided with conduction holes are arranged between the launching cylinders and the bases thereof. For the manufacturing method, the launching cylinders are manufactured by compression molding in a discharge type and / or an over stroke type compression molding manner. The manufacturing die comprises die casings and die cores, wherein the die cores comprise core bases and hollow hole manufacturing rods, and overpressure holes corresponding to the hollow hole manufacturing rods are respectively formed in base plates of the die casings.

Description

technical field [0001] The invention relates to a firework launching device used for launching and setting off fireworks, a manufacturing method and a mold thereof. Background technique [0002] In the current production process of fireworks and firecrackers, fireworks shells and launching devices are generally integrated. When the fireworks are set off, the bulky fireworks packaging and launching devices will also become a pile of garbage along with the setting off of the fireworks. This will greatly increase the on-site sanitation cleaning work after setting off. What's more, it wastes a lot of resources and increases manufacturing and transportation costs. And its manufacturing process is relatively complicated. And this one-piece firework effect ball is inconvenient to set off, and the lead wire is exposed, so there is a potential safety hazard. However, in the prior art, the launching device is made into a single launching tube, and the launching tubes are bundled to...

What's more, it wastes a lot of resources and increases manufacturing and transportation costs

And its production process is relatively complex

And this one-piece firework effect ball is inconvenient to set off, and the lead wire is exposed, so there is a potential safety hazard

However, in the prior art, the launching device is made into a single launching tube, and the launching tubes are bundled together with a binding piece, and then relatively independent effect balls are respectively arranged and prepared for each launching tube, and several effect balls need to be connected in series with lead wires. On the one hand, the structural method is not safe to use, and it is very inconvenient. The lead wire and the effect ball are assembled and connected separately. The process is not only troublesome, but also particularly unsafe.

The common defect of the above two methods is that not only the manufacturing process is particularly cumbersome and complicated, but also the cost of manufacturing and discharging is relatively high.

In particular, the existing fireworks launching devices of this type are basically made of paper materials. The overall structure of the cylinder is not reliable, the strength is poor, and it is easy to be damp. After the launching cylinder is completed, it needs to be manually ground with yellow mud. , After the launching tube is formed, it is necessary to manually open the fuze eye. The production quality of the launching tube cannot guarantee the most basic mechanical strength, and it is easy to be affected by moisture, which makes the overall safety performance poor. life safety

In addition, due to the defects in the single and integrated structures of the existing launching devices, as well as the unreasonable way of launching and igniting, etc., it is impossible to truly realize the intermittent (intermittent) continuous launching of several tubes of fireworks. Obtain a satisfactory discharge effect
