Production of glass bottle solve profiling mould cracks

Die

root cause analysis:

1. ； Mouth mold joint surface wear that fall outside the bottle blowing;

　　2。 ； Blow QiTou too shallow, touching the bottle; Blow QiTou too deep, cause material blown QiTou cone up; Mouth mold size is too large; Type at the beginning of a mould cavity volume is not enough; Early in the mold cavity shape is not appropriate, need stamping pressure is higher; Stamping mouth too small; Core tip is too long; Change the mouth mould; Check the blow QiTou, modify the depth to the appropriate; Check the blow QiTou, modify the depth to the appropriate; Switch to smaller mouth mould; Increasing volume type at the beginning of a mould cavity; Modification in the mold cavity at the beginning of design, and make it easy to stamping; Increasing the stamping mouth size; Shorter tip.

note: in the early type mold side fracture in the form of cracks are neat vertical cracks generated in a forming die side mostly with broken

traces. For the solution of two ways, 1. For cooling; 2 for the vibration of the mechanical movement caused by the unreasonable!
