Capacity adjustment device of rotary bottle blowing die

Abstract

The invention discloses a capacity adjustment device of a rotary bottle blowing die, which comprises the bottle blowing die, wherein the bottle blowing die is divided into a left die and a right die; and a bottle-shaped die cavity is reserved in the bottle blowing die, and is divided into an upper part, a middle part and a lower part. The capacity adjustment device of the rotary bottle blowing die is characterized in that: a capacity adjustment groove is formed on the wall of the middle part of the bottle-shaped die cavity; fixing holes are reserved in the capacity adjustment groove, and are communicated with the outer wall of the die; and a capacity adjustment block is arranged in the capacity adjustment groove, and is fixed with the capacity adjustment groove by bolts. The capacity adjustment device can realize the processing of plastic bottles with different capacities by the same die, and conveniently realizes adjustment without reopening the die so as to greatly save the cost; and patterns also can be engraved on the outer wall of the capacity adjustment block, and are convenient to change.

Description

technical field [0001] The invention relates to a bottle blowing mold of a rotary bottle blowing machine, in particular to a capacity adjustment device for a rotary bottle blowing mold. Background technique [0002] Most of the mold cavity structure of the existing rotary blow molding machine blowing mold is fixed and cannot be changed, especially the capacity of the blown bottle cannot be changed, but because the shrinkage rate of the bottle is different in summer and winter, the weather in summer The extreme heat causes the bottle to expand, making the beverage of the same volume in the bottle appear less, while the weather is cold in winter, causing the bottle to shrink, making the beverage of the same volume in the bottle full, so it is usually refilled according to the different weather in summer and winter. Open the mold and slightly adjust the capacity of the bottle, but the cost of re-opening the mold is very high, and it is time-consuming and laborious. Contents o...
