The utility model relates to an improved adjustable
plastic bottle blowing mold. The improved adjustable
plastic bottle blowing mold comprises a bottom plate, a base, a mold cylinder, a material injection
pipe and an adjusting
assembly, the mold
barrel is installed on the bottom plate through the base, the feeding end of the mold
barrel is sleeved with the material injection
pipe, the material injection
pipe is communicated with the mold
barrel, and the adjusting
assembly is arranged on the bottom plate; an injection molding cavity is formed in the mold cylinder in the transverse direction, the adjusting
assembly comprises at least two supporting plates, and the at least two supporting plates are both perpendicularly installed on the bottom plate. According to the improved adjustable
plastic bottle blowing mold, the output end of the air cylinder stretches out and draws back to drive the adjusting plate connected with the output end of the air cylinder to extend into the mold barrel, when the depth of the adjusting plate extending into the mold barrel is deeper, the length of an injection-molded plastic
bottle is shorter, and meanwhile the air cylinder is electrically connected with
control equipment in the outside, so that the plastic
bottle is more stable in injection molding. And the extending length of the output end of the air cylinder can be effectively and accurately adjusted, so that the length of an injection-molded plastic
bottle is adjusted.
