Combined firework emitter cold pressing combined die

Abstract

The invention discloses a combined firework emitter cold pressing combined die which comprises a cover plate, shaft rods, outer dies and a box body. The cover plate is connected with the box body, andthe shaft rod penetrates through the box body and an inner cavity of the outer die. The combined firework emitter cold pressing combined die is characterized in that the shaft rods comprise the multiple driven shaft rods and one driving shaft rod, the outer dies comprise the right outer die and the left outer die, the upper portions of the multiple driven shaft rods and one driving shaft rod areeach provided with a rotating device used for being mutually engaged and connected for rotation, the top end of the driving shaft rod is provided with a transmission device, and the top ends of the right outer die and the left outer die are connected with a die removal device used for removal and separation of a forming barrel. The multiple driven shaft rods and the driving shaft rod are movably connected with a bottom plate of an inner cavity of the box body and the top of the cover plate through cooperation of an upper bearing and a lower bearing, the right outer die and the left outer die are in buckled connection through a lock catch device, and the shaft rods are of a three-stage circular truncated cone step structure. The combined firework emitter cold pressing combined die has the advantages of being easy to assemble, high in production efficiency, low in cost and the like.

Description

technical field [0001] The invention relates to a device for forming a fireworks cylinder, in particular to a combined firework launcher cold-pressing combination mold. Background technique [0002] In the prior art, the one-time molded combined fireworks barrel is molded by a hot-pressed barrel structure mold, that is, the forming shaft is hollow and straight, and the outer mold is an integral barrel. This hot-pressed tubular barrel There are the following disadvantages in the cylinder formed by the construction mold: first, the hot pressing time is long, because it is closed, the heat dissipation is slow, and the hardening time is long. It takes 30 minutes for each hot pressing to release the mold; second, the surface of the processed cylinder is If it is rough, the wall of the cylinder cavity is easy to be rough and not smooth; third, it consumes a lot of power, has low production efficiency and high cost. For this reason, it is very necessary and promising to develop an...
