Abstract
The utility model relates to the once shaped mandrel that a kind of glass blows machine, it comprises tight head, ventilation nut, spring, gland, packing, gland nut and ventpipe, in tight head inner chamber, be provided with a stripper loop inner chamber of tight head is separated into venting cavity and annular seal space, the annular seal space that ventpipe passes tight head extend in venting cavity, ventilation nut thread is connected to the end of the ventpipe extend in venting cavity, and the ventpipe in the annular seal space of tight head is set with spring, gland, packing and gland nut successively; Wherein, gland nut is threaded with the chamber wall of annular seal space, and packing is heat resistant rubber circle.The utility model adopts heat resistant rubber circle as packing, and its wear resisting property is good, long service life; Elastic deformation is strong, and sealing is reliable, and it is convenient to change, and production efficiency is higher.
Description
Technical field
The utility model relate to a kind of manufacture glasswork blow machine component, especially a kind of glass blows the once shaped mandrel of machine.
Background technology
We know, in the one-shot forming technique of glasswork, are the plasticity-utilizing glass metal, glass metal are formed the gob of setting weight and shape through feeding machine, cut in parison mo(u)ld and blow out or be pressed into just type, then proceed in shaping mould and blow out goods.When the blowing to glasswork, blow head extend in glass metal, the high pressure gas blown out by blow head are by glass metal blow molding, and high pressure gas are ventpipe supplies of mandrel, blow head turnover glass metal causes the change of stroke then to need the ventpipe of mandrel to move up and down to compensate, therefore, the sealing effectiveness of the ventpipe of mandrel plays an important role to the quality of product, output.
At present, glass blows the mandrel that machine uses and comprises tight head, ventilation nut, spring, gland, packing, gland nut and ventpipe, ventpipe extend into tight head inside, between tight head and ventpipe, axially spring, gland, packing and gland nut are housed successively.Existing packing all adopts oil immersion asbestos packing, and wear resisting property is poor, and the life-span is short; When changing, need special tool to take, the scope of application is little, maintenance trouble; Will shear oil immersion asbestos packing ring and check in installation process, constantly its parameter of adjustment, waste time and energy, production efficiency be lower.
Summary of the invention
In order to the packing employing oil immersion asbestos packing overcoming mandrel in prior art exists the deficiency that the life-span is short, the scope of application is little, maintenance bothers, production efficiency is lower, the utility model provides a kind of long service life, seals reliable, that replacing is convenient, production efficiency is high once shaped mandrel.
The utility model solves the technical scheme that its technical problem adopts: a kind of glass blows the once shaped mandrel of machine, it comprises tight head, ventilation nut, spring, gland, packing, gland nut and ventpipe, it is characterized in that: in described tight head, be provided with through inner chamber, in tight head inner chamber, be provided with a stripper loop inner chamber of tight head is separated into venting cavity and annular seal space, the annular seal space that described ventpipe passes tight head extend in venting cavity, described ventilation nut thread is connected to the end of the ventpipe extend in venting cavity, ventpipe in the annular seal space of tight head is set with spring successively, gland, packing and gland nut, wherein, described gland nut is threaded with the chamber wall of annular seal space, and described packing is heat resistant rubber circle.
The utility model adopts heat resistant rubber circle as packing, with existing employing oil immersion asbestos as compared with packing, and the heat resistant rubber circle that the utility model uses, wear resisting property is good, long service life; The squeezing action of the chamber wall of ventpipe and annular seal space can make the elastic deformation of heat resistant rubber circle, and to reach good sealing function, its sealing, use are reliably; In Renewal process, utilize the elasticity of rubber ring by large for the support of its internal diameter, unclamp after being sleeved on the corresponding position of ventpipe, make its lock ring at the outer wall of ventpipe, do not need use instrument, applied widely, production efficiency is higher.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the main sectional view of a kind of structure of the present utility model.
Mark in figure: 1. tight head, 101. stripper loops, 102. venting cavities, 103. annular seal spaces, 2. ventilate nut, 3. spring, 4. gland, 5. packing, 6. gland nut, 7. ventpipe.
Embodiment
In FIG, a kind of glass blows the once shaped mandrel of machine, and it comprises tight head 1, ventilation nut 2, spring 3, gland 4, packing 5, gland nut 6 and ventpipe 7.
As shown in Figure 1, in tight head 1, be provided with through inner chamber, in tight head 1 inner chamber, be provided with a stripper loop 101 inner chamber of tight head 1 is separated into venting cavity 102 and annular seal space 103.
The annular seal space 103 that ventpipe 7 passes tight head 1 extend in venting cavity 102.
In FIG, ventilation nut 2 is threaded in the end of the ventpipe 7 extend in venting cavity 102, and ventpipe 7 is in the process of moving up and down, and ventilation nut 2 coordinates with stripper loop 101 and plays position-limiting action to ventpipe 7.
As shown in Figure 1, the ventpipe 7 in the annular seal space 103 of tight head 1 is set with successively spring 3, gland 4, packing 5 and gland nut 6.Wherein, packing 5 is heat resistant rubber circle.
Gland nut 6 is threaded with the chamber wall of annular seal space 103, by the pretension of gland nut 6, the axial compression of gland nut 6 and spring 3 makes heat resistant rubber circle produce deformation, thus is adjacent to ventpipe 7 and the chamber wall of annular seal space 103 more closely, reaches better sealing purpose.
In use, ventpipe 7 realizes moving up and down through External Force Acting, and high pressure gas can flow through through the venting cavity 102 of tight head 1 and be arranged in the ventpipe 7 that this one end, chamber is fixed with ventilation nut 2, realize the output of gas in ventpipe 7.Meanwhile, ventpipe 7 and the chamber wall of annular seal space 103 are close in the elastic deformation of heat resistant rubber circle, better solve the sealing problem between ventpipe 7 and tight head 1.
The utility model long service life, sealing are reliably, replacing is convenient, production efficiency is high.
