Pressing die for continuous pattern on surface of thin-walled metal shell of cup or kettle

Abstract

The invention discloses a pressing die for the continuous pattern on the surface of a thin-walled metal shell of a cup or a kettle. The pressing die comprises an upper die force applying positioning assembly, a lower die positioning assembly, a female die assembly and a male die assembly. The upper die force applying positioning assembly comprises a die closing ring. The lower die positioning assembly comprises a positioning cavity. The female die assembly comprises a female die defined by a plurality of female die blocks. An inclined face in sliding fit with the inclined inner wall of the dieclosing ring is arranged at the outer end of a die closing push block. The male die assembly comprises a male die defined by a plurality of male die blocks and a male die core. In the die closing state, the continuous groove pattern surrounding the inner wall of the female die corresponds to the continuous protruding edge pattern surrounding the outer wall of the male die. By the adoption of thepressing die for the continuous pattern on the surface of the thin-walled metal shell of the cup or the kettle, it can be guaranteed that the pressed continuous pattern on the surface of the thin-walled metal shell of the cup or the kettle is high in definition and free of deviation and can ensure that the thin-walled metal shell is not lost and cracked, the yield is greatly increased, and the production efficiency is greatly improved.

Description

technical field [0001] The present invention relates to cups and jugs, and in particular to integral one-piece molds for continuous patterns of thin-walled metal casings surrounding cups or jugs. Background technique [0002] The surface patterns of current cups and pots with metal shells are basically made by techniques such as printing and dyeing, laser marking, or small-area pressed patterns. In the industry, there is no product that surrounds the thin-walled metal shell of the cup or kettle or even 360° integrally presses the pattern. It is now known that the production process of the pressed pattern is to use rolling. The mold is composed of a concave die and a punch. The inner wall has a groove pattern corresponding to the rib pattern or a rib pattern corresponding to the groove pattern. The metal shell of the cup or pot is set on the punch, and the corresponding ribs are formed by the rotation of the punch and the die. and grooves extrude small local patterns that s...

Problems solved by technology

However, the mold of this rolling process is easy to cause the deviation of the pattern, the pattern definition is not high, and the metal shell is seriously out of round after rolling, and even cracked. The technology is very immature and cannot be mass-produced
