Stamping assembly of bottle moulding

Abstract

The invention discloses a stamping assembly of bottle moulding. The stamping assembly comprises a die and a ring, wherein a first through-hole and a second through-hole used for moving in and out for a punch are respectively arranged in the die and the ring, the ring is arranged in the die and is integrally composed of a retainer ring and a supporting ring, a diameter of the supporting ring is less than that of the retainer ring, the retainer ring clamps the die, the punch is sleeved in the first through-hole and the second through-hole, and a head of the punch exposes out of the die. Periphery of the die is projected with a positioning ring for connecting a hold plier, the positioning ring is provided with a plurality of heat dissipating grooves along a circumferential direction, and the heat dissipating grooves are arranged along a moving direction of the punch. According to the invention, the positioning ring of the die is provided with the plurality of heat dissipating grooves along the circumferential direction, and the heat dissipating grooves are arranged along the moving direction of the punch, so that the stamping assembly can rapidly sending out the heat, and thus improve mouth moulding of the bottle and increase processing quality.

Description

technical field [0001] The invention relates to a bottle blank processing accessory, in particular to a 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, it was found that due to the impact force of the punch, the temperature of the upper part of the mouth die was high, which was not conducive to the forming of the mouth of the bottle and would cause mouth swelling. Contents of the invention [0004] The present invention overcomes the sh...
