Die used for bottle molding and stamping assembly

Abstract

The invention discloses a die used for a bottle molding and stamping assembly. The die is composed of two semi-rings. A first through hole is arranged in the die to allow a punch to enter and exit; positioning loops used for connection with holding clamps are projected at the periphery of the die; and a plurality of air discharge ducts are arranged at the bottom of the die. According to the invention, since the plurality of air discharge ducts are arranged at the bottom of the die, air can be discharged when the punch rapidly travels, so the pressure of the punch is reduced, and the die is effectively protected.

Description

technical field [0001] The invention relates to a bottle forming stamping assembly, in particular to a die for the bottle forming stamping assembly. Background technique [0002] The processing of the rough bottle is generally divided into two methods: blow blowing and pressure blowing. The pressure blowing method is to press the bottle through the stamping assembly once, and blow it again to form the rough bottle; the existing stamping assembly is made of The die, the mouth ring and the punch are composed of three parts, but the existing stamping assembly will cause many problems due to the unreasonable structural design, which will affect the processing quality of the bottle. [0003] For example, because the punch moves faster in the die, it will generate a larger air pressure, which will increase the pressure of the punch and cause damage to the die over time. Contents of the invention [0004] The invention overcomes the disadvantages in the above-mentioned prior art...

The pressure blowing method is to press the bottle through the stamping assembly once, and blow it again to form the rough bottle; the existing stamping assembly is made of The die, the mouth ring and the punch are composed of three parts, but the existing stamping assembly will cause many problems due to the unreasonable structural design, which will affect the processing quality of the bottle

[0003] For example, because the punch moves faster in the die, it will generate a larger air pressure, which will increase the pressure of the punch and cause damage to the die over time.
