Abstract
The invention discloses a falling-prevention seal ring sprue sleeve. The falling-prevention seal ring sprue sleeve comprises a sprue sleeve body; the sprue sleeve body is internally provided with a hot nozzle installation cavity; the front end part of the sprue sleeve is provided with a gum flow through hole, and the rear end part of the sprue sleeve is provided with an installation step; the shoulder part of the installation step is provided with an annular seal ring groove which is internally provided with a seal ring; the opening part of the seal ring groove is provided with an inverted buckle for preventing falling. The sprue sleeve provided by the invention is simple in structure, is reasonable in design, enables the seal ring to be clamped by the inverted buckle by adding the inverted buckle at the opening part of the seal ring groove, can guarantee that the seal ring cannot fall off in installation, and effectively solves the problem that the seal ring falls off to be damaged by pressing.
Description
Technical field
The present invention relates to the hot runner mould of injection mo(u)lding, particularly the sealing ring anticreep sprue bush of hot mouth special use 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 mould.TOP-TIP as 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 designed 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, when the sprue bush body is fit into mould, sealing ring 6 easily comes off out, bad by sprue bush and mould extruding, cause losing sealing, affect the system normal operation.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of sealing ring anticreep sprue bush.
Technical solution of the present invention is achieved in that a kind of sealing ring anticreep sprue bush, comprises the sprue bush body, is provided with hot mouth installation cavity in described sprue bush body; The leading section of described sprue bush body is provided with the 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 the O-ring seal groove center.
Preferably, described back-off is arranged on from the side away from the O-ring seal groove center.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of sealing ring anticreep sprue bush of the present invention, because the oral area at the ring packing ring recess has increased back-off structure, make sealing ring be blocked by back-off, can guarantee that in installation process sealing ring does not come off, effectively solve the problem that sealing ring comes off and damaged by pressure, also guaranteed good sealing property.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation that accompanying drawing 1 is sprue bush in prior art;
The local enlarged diagram that accompanying drawing 2 is sprue bush in prior art;
The structural representation that accompanying drawing 3 is a kind of sealing ring anticreep sprue bush of the present invention;
The local enlarged diagram that accompanying drawing 4 is a kind of sealing ring anticreep sprue bush of the present invention;
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 accompanying drawing, the present invention is described.
Accompanying drawing 3,4 is a kind of sealing ring anticreep sprue bush of the present invention, 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 present invention compared with prior art has following advantages:
A kind of sealing ring anticreep sprue bush of the present invention, because the oral area at seal groove has increased back-off structure, make sealing ring be blocked by back-off, can guarantee that in installation process sealing ring does not come off, effectively solve the problem that sealing ring comes off and damaged by pressure, also guaranteed good sealing property.
Above-described embodiment is only explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
