Pressing die device for manufacturing fireworks outer cylinder and process method thereof

Abstract

The invention provides a die pressing device for manufacturing a fireworks outer cylinder with novel structure and material characteristics as well as improved good properties, and a using method thereof. The die pressing device comprises an upper die, a middle die and a bottom die, wherein the upper die comprises a first template, a second template, a third template and a plurality of column pipes with sealed ends and opened ends; and heating channels which are used for heating and dewatering a material and are formed by curing in a die pressing process are arranged on the upper die, a lower die and the bottom die. Compared with the traditional process, the die pressing device and an operation technology provided by the invention have the advantages of simple process, convenience in operation, high industrialization, easiness of automatic control, stable and reliable product quality and the like.

Description

technical field [0001] The invention relates to the manufacturing technology of fireworks salutes, in particular to a molding device for making a fireworks outer cylinder with novel structure and material characteristics and improved excellent performance characteristics and a use method thereof. Background technique [0002] Setting off fireworks and firecrackers, especially in my country, is a traditional way for people to add atmosphere to various festivals and celebrations. Fireworks and firecrackers have been set off among the people in my country for more than 1,300 years, and the production and sales of fireworks and firecrackers and salutes have reached billions of yuan nationwide. [0003] Yet fireworks and firecrackers, salute are to adopt traditional craft method and adopt traditional material preparation usually. As far as the production process of ordinary salutes is concerned, according to the traditional method, the barrel base with multiple barrels is compos...

Problems solved by technology

[0004] In addition, due to the limitation of the material strength and toughness of the paper gun barrel, the expansion force generated by the gunpowder at the moment of firing the gunpowder will cause the phenomenon of blasting, loosening and reversing the barrel, which poses a safety hazard

Furthermore, the papery gun barrel is easily soaked by rainwater, causing the gun barrel and the lead wire to be damp, so that the salute can not be used or the gunpowder therein burns insufficiently to produce harmful gas, which is neither safe nor environmentally friendly.
