In order to achieve the above object, the utility model is by the following technical solutions: a kind of end, is to bottom blowing bottle mould, comprise mould bases, the mould bases upper end is last bottleneck mold insert, last bottleneck mold insert is upper impression down, it under the upper impression last bottle end mold insert, mold insert at the bottom of last bottle end mold insert is following bottle down, following bottle end mold insert is lower impressions down, bottleneck mold insert under under the lower impressions being, the folding part that has elastic bumps when having one to make the demoulding between last bottle end mold insert and the mold insert at the bottom of following bottle, the tensile elongation of folding part is more than or equal to the degree of depth sum that caves inward bottom the degree of depth that caves inward bottom the upper impression and the lower impressions.
Preferably, described folding part tensile elongation equals the degree of depth sum that the degree of depth that the upper impression bottom caves inward caves inward bottom lower impressions.
Preferably, described folding part is " V " or " M " shape structure, specifically according to the Design of length that stretches.
A kind of end, may further comprise the steps the manufacture method of bottom blowing bottle mould:
(1), according to designing requirement, offer the bottleneck mold insert in mould bases upper end, last bottleneck mold insert is upper impression down, be last bottle end mold insert under the upper impression, last bottle end mold insert for mold insert at the bottom of following bottle, is a lower impressions under the following bottle of end mold insert down, under the lower impressions be under the bottleneck mold insert;
(2), the degree of depth sum that bottom lower impressions, caves inward of the degree of depth that caves inward more than or equal to upper impression bottom according to the folding part tensile elongation, mould is offered the folding part;
(3), mould shape.
Folding part tensile elongation in the described step (2) equals the degree of depth sum that the degree of depth that upper impression bottom caves inward caves inward bottom lower impressions.
" V " or " M " shape structure is selected according to tensile elongation in folding part in the described step (2).
The utility model has following advantage and effect with respect to prior art:
1, the utility model adopts and comprises mould bases, the mould bases upper end is last bottleneck mold insert, last bottleneck mold insert is upper impression down, it under the upper impression last bottle end mold insert, mold insert at the bottom of last bottle end mold insert is following bottle down, following bottle end mold insert is lower impressions down, bottleneck mold insert under under the lower impressions being, the folding part that has elastic bumps when having one to make the demoulding between the mold insert at the bottom of last bottle end mold insert and following bottle, the degree of depth sum that the degree of depth that the tensile elongation of folding part caves inward more than or equal to upper impression bottom caves inward bottom lower impressions has solved the bottleneck problem of the end to bottom die targetedly.This structure makes the end come true to mould bases tool volume production, and energy consumption is constant, and output doubles, and that the design has is simple in structure, make easily, operating flexibility, saving is artificial, production capacity is high, production efficiency is high and characteristics such as qualification rate height.
2, the folding part in the utility model, resilient projection between expect on bottle base material and following bottle of base on the product of producing, corresponding length can stretch, this position is stretched during product stripping, product is deviate from from die cavity smoothly, and transfers to secondary mould, carries out back-end crop in secondary mould, qualification rate is from original 40%, brings up to present more than 95%.
3, the product produced of the utility model, positioner are not found loosening phenomenon, need not to arrange 2 people to check on the quality behind the back-end crop.
4, the utility model qualification rate height can be stopped to shut down and adjust mould clip position, enhances productivity.
