Problems solved by technology

However, if the gap X is large, it will cause blowing air leakage as described above, and the blowing performance will be reduced
Additionally, product specifications will not be met
In other words, if the gap X is made small to improve blow molding performance, mold bite will occur; and if the gap X is made large to prevent mold bite, blow molding performance will be reduced

Embodiment 1

[0051] refer to Figures 1 to 4 A description is given of the mold for blow molding according to the embodiment. The blow molding mold 10 according to the present embodiment is a mold for blowing a parison 20 to mold an article 30 .

[0052] First, an explanation of the constant velocity joint is given. The constant velocity joint is configured to engage an input shaft and an output shaft arranged to change the angle of intersection between them in such a manner that a constant velocity rotation can be transmitted from the input shaft to the output shaft, and within one of these shafts a There is a housing (bell housing) that accommodates the support. In order to seal the lubricant (usually grease) inside the joint and prevent water, muddy water, etc. from invading the inside of the joint, a constant velocity joint dust cover is installed.

[0053] Next refer to figure 2 and 3 A description is given of a constant velocity joint boot, an article corresponding to an interm...

Abstract

A mold for blow molding with which a molded thermoplastic-elastomer article having a stable shape can be molded by preventing a parison from being caught in the mold while maintaining suitability for blowing. The mold (10) for blow molding has an annular loosely surrounding part (12) for loosely surrounding an end part (22) of a parison (20), and is characterized in that after mold clamping, the clearance between the outer circumferential surface of the end part (22) and the inner circumferential surface of the loosely surrounding part (12) as measured at the parting lines (P) of the mold is larger than the clearance as measured in any part other than the parting lines (P).

Description

technical field [0001] The present invention relates to a (metal) mold / mold (gold mold) for blow molding, and more particularly to a tool for blow molding elastomeric objects for use as constant velocity joint boots mold. Background technique [0002] The constant velocity joint is configured to engage an input shaft and an output shaft, the input shaft and the output shaft are arranged to change the angle of intersection between them in such a manner that a constant velocity rotation can be transmitted from the input shaft to the output shaft, and a housing is provided in one shaft. Housing of the support / bearing (bell housing). In order to seal the lubricant (usually grease) inside the joint and prevent water, muddy water, etc. from invading the inside of the joint, a constant velocity joint dust cover is installed. The constant velocity joint boot has an elastically deformable corrugated portion, a large-diameter cylindrical portion formed at one axial end of the corrug...
