Radial quick release sealing unit of blow molding machine and quick release method

Abstract

The invention discloses a radial-direction quickly-disassembled sealing unit for a blow molding forming machine. The unit is arranged on a gas-blowing apparatus and can be split and assembled; the gas-blowing apparatus possesses a pedestal, and a telescopic rod is arranged on the pedestal; the radial-direction quickly-disassembling sealing unit comprises a sleeving member, a sealing end member and a radial-direction operation member. The invention also discloses a quickly-disassembling method of the radial-direction quickly-disassembled sealing unit of the blow molding forming machine. The telescopic rod is sleeved by the sleeving member possessing the sealing end member, and the sleeving member clamps or get loose from the telescopic rod by cooperating with the operation member in a linear shift way, and the method mainly comprises enabling the radial-direction operation member to have a radial-direction shift for finishing a disassembling and changing motion, and the method does not need time-consuming screw-lock rotating motion. The method is low in operation difficulty, actually helps to improve the disassembling and changing efficiency and improves convenience for disassembling and changing.

Description

technical field [0001] The invention relates to a sealing device in a blow molding process, in particular to a radial quick-release sealing unit and a quick-release method of a blow molding machine. Background technique [0002] In the general blow molding process, when performing mold closing and blow molding, multiple sealing mechanisms of the sealing unit must be fitted onto the teeth of the preform to be formed one by one to ensure that the shape of the teeth of the preform is not damaged. And it can prevent the abnormal phenomenon of gas leakage during blow molding, while the common sealing device 10 such as figure 1 As shown, the sealing device 10 includes a telescopic displacement displacement member 11 and a sealing end member 12, the outer peripheral edge of the end of the displacement member 11 has an external thread portion 111, and the inner peripheral edge of the sealing end member 12 has a Internal threaded part 121, the sealing end piece 12 is screwed and arr...

[0002] In the general blow molding process, when performing mold closing and blow molding, multiple sealing mechanisms of the sealing unit must be fitted onto the teeth of the preform to be formed one by one to ensure that the shape of the teeth of the preform is not damaged. And it can prevent the abnormal phenomenon of gas leakage during blow molding, while the common sealing device 10 such as figure 1 As shown, the sealing device 10 includes a telescopic displacement displacement member 11 and a sealing end member 12, the outer peripheral edge of the end of the displacement member 11 has an external thread portion 111, and the inner peripheral edge of the sealing end member 12 has a Internal threaded part 121, the sealing end piece 12 is screwed and arranged on the external threaded part 111 at the end of the displacement member 11 through the internal threaded part 121, and the sealing device 10 is sealed through the sealing end piece 12 However, when the size of the blow-molded preform changes, the operator must unscrew the sealing end piece 12 one by one and then tighten and replace the sealing end piece 12 of the corresponding size, which is very inconvenient in operation, and once the When the number of sealing devices 10 of the sealing unit is huge, the difficulty in operation will be added.
