Description

Technical Field

[0001] The utility model relates to the technical field of injection-blowing molds, in particular to an injection-blowing integrated bottle mold structure. Background Art

[0002] Injection blow molding is a plastic product processing technology. Its principle is to blow the heated and melted plastic into the mold through high-pressure air, and then quickly cool it into shape. The plastic products manufactured by this method are of high quality and thin wall, and are suitable for manufacturing hollow containers such as bottles and barrels. Traditional injection blow molding uses extruded embryo tubes in the bottle blowing machine. The weight deviation is relatively large and then transferred to the bottle blowing mold cavity. The bottle is blown into shape with a blowing pen. After molding, subsequent processes are required to cut off the excess corners of the edges. Due to equipment limitations, 2-cavity or 4-cavity synchronous production is mostly used, the daily output is relatively low, and a lot of scraps will be generated, which is difficult to recycle and has a large loss. For this reason, we propose an injection-blowing integrated bottle mold structure. Utility Model Content
