Abstract
The utility model relates to an anti-off sprue bush of a sealing ring. The anti-off sprue bush of the sealing ring comprises a sprue bush body, wherein a hot nozzle mounting cavity is formed in the sprue bush body, a flowing glue through hole is formed in the front end part of the sprue bush, a mounting step is arranged at the rear end part of the sprue bush, an annular sealing ring groove is formed in the shoulder part of the mounting step, a sealing ring is arranged in the annular sealing ring groove, and an anti-off inverted buckle is arranged at the opening part of the sealing ring groove. The anti-off sprue bush has a simple structure and is reasonable in design, the inverted buckle is additionally arranged at the opening part of the sealing ring groove to invertedly buckle and clamp the sealing ring, the sealing ring cannot drop off during installation, and the problem that the sealing ring drops off and is crushed is effectively solved.
Description
Technical field
The utility model relates to the hot runner mould of injection mo(u)lding, particularly the special sealing ring anticreep sprue bush of hot mouth in a kind of needle valve type hot runner system.
Background technology
At present, in the application of injection mo(u)lding Hot runner Technology, most TOP-TIPs all adopt the hot mouth structure with sprue bush.The described hot mouth structure with sprue bush: instant heating mouth leading section carries a sprue bush, refills and is fitted on mold integral.As the TOP-TIP of needle valve; owing to being provided with sprue bush, its needle just can directly not contact with the cast gate of mould, and plastic rubber material has acid or corrosive a bit in addition; sprue bush just can be protected the gate portions of mould effectively, increases the service life of system.
The sprue bush designing routinely at present, as described in Fig. 1,2, oral area for seal groove 5 that sealing ring 6 is installed on sprue bush body 1 is flat mouth, in the time that sprue bush body is fit into mould, sealing ring 6 easily comes off out, bad by sprue bush and mould extruding, cause losing sealing, the system that affects is normally worked.
Utility model content
The utility model object is that a kind of sealing ring anticreep sprue bush is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sealing ring anticreep sprue bush, comprise sprue bush body, and in described sprue bush body, be provided with hot mouth installation cavity; The leading section of described sprue bush body is provided with gummosis through hole, rearward end is provided with installation step, the shoulder of described installation step is provided with annular seal groove, in described seal groove, is provided with sealing ring, and the oral area of described seal groove is provided with the back-off of slip-off preventing.
Preferably, described back-off is arranged on from the side close to O-ring seal groove center.
Preferably, described back-off is arranged on from the side away from O-ring seal groove center.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of sealing ring anticreep sprue bush of the utility model scheme, owing to having increased back-off structure at the oral area of ring packing ring recess, sealing ring is blocked by back-off, in installation process, can guarantee that sealing ring does not come off, effectively solve the sealing ring problem of being damaged by pressure that comes off, also guaranteed good sealing property.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of sprue bush in prior art;
Accompanying drawing 2 is the local enlarged diagram of sprue bush in prior art;
Accompanying drawing 3 is the structural representation of a kind of sealing ring anticreep sprue bush of the present utility model;
Accompanying drawing 4 is the local enlarged diagram of a kind of sealing ring anticreep sprue bush of the present utility model;
Wherein: 1, sprue bush body; 2, hot mouth installation cavity; 3, gummosis through hole; 4, installation step; 5, seal groove; 6, sealing ring; 7, back-off.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 3,4 is a kind of sealing ring anticreep sprue bush described in the utility model, comprises sprue bush body 1, is provided with hot mouth installation cavity 2 in described sprue bush body 1; The leading section of described sprue bush body 1 is provided with gummosis through hole 3, rearward end is provided with installation step 4, the shoulder of described installation step 4 is provided with seal groove 5, in described seal groove 5, is provided with sealing ring 6, and the oral area of described seal groove 5 is provided with the back-off 7 of slip-off preventing; In the present embodiment, described back-off 7 is arranged on from the side close to the center of ring packing ring recess 5, and certainly, described back-off 7 also can be arranged on from the side away from the center of ring packing ring recess 5.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of sealing ring anticreep sprue bush of the utility model scheme, because the oral area at seal groove has increased back-off structure, sealing ring is blocked by back-off, in installation process, can guarantee that sealing ring does not come off, effectively solve the sealing ring problem of being damaged by pressure that comes off, also guaranteed good sealing property.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
