Abstract

The invention discloses a manufacturing method of a lighter nozzle and a mold used for the method. The manufacturing method uses low-carbon steel pipes as raw materials, and includes the steps of cutting, cold heading, drilling transverse holes, turning springboard grooves, and the like. The mold includes a support, a first mold, a return spring, a first lock, a second mold, a third mold and a fourth mold. The first mold is assembled in the through hole of the support, and there is a nozzle in it that is compatible with the finished product. The outer diameter of the front part is the same as the first through hole, the second mold is provided with the second thimble matching the first through hole, so as to form the front part of the nozzle, and the outer diameter of the rear part of the finished nozzle is set in the fourth mold Consistent bore into which a fourth ejector pin fits to shape the rear of the nozzle and the shoulder ring. The method of the invention has the advantages of simple process, high production efficiency, low raw material cost and processing cost, low material loss, etc. The mold has the advantages of simple structure and convenient use, and is especially suitable for manufacturing lighter nozzles.

Description

technical field

[0001] The invention relates to lighter parts, in particular to a manufacturing method of a lighter nozzle and a mold used in the method. Background technique

[0002] At present, the competition in the lighter market is very fierce, and price reduction is usually one of the main means of competition for manufacturers. Therefore, how to control or reduce even a little production cost of lighters is of great importance to manufacturers. The nozzle is one of the parts of the lighter, and it is installed at the outlet of the gas storage chamber. When the lighter is in use, the gas in the gas storage chamber is sprayed out through the nozzle and ignited by the ignition mechanism. The manufacturing method of existing lighter nozzle generally has following several: 1, is raw material with copper bar, adopts modes processing moldings such as lathe turning and drilling machine punching. Its shortcomings are: high raw material prices, large material loss, many proce...
