Abstract
The utility model relates to a compensation air seal ring which comprises an annular seal ring body made of an elastic material, wherein cross sections of the seal ring body are U-shaped, and all the U-shaped openings face the center of the seal ring. The compensation air seal ring adopts the U-shaped cross sections, therefore, the compensation range is larger, and the seal ring is not prone to aging when the seal ring is in a compression state all along, the elasticity can be guaranteed, and the reliability of the compensation air is guaranteed.
Description
Technical field
The utility model relates to a kind of complemental air seal ring for bottle blowing machine.
Background technique
in bottle blowing machine, involutory left mould and right mould all is arranged in support mutually, the left and right sides of support is respectively arranged with screw, screw passes support and is threaded mutually with left mould and right mould respectively, be provided with spring on screw between screw afterbody and support, the inner left wall of support and right side inwall are respectively arranged with the complemental air seal ring, the outer wall of the complemental air seal ring on the left of being positioned at and the inner left wall of support and left mould encloses an airtight left cavity, be positioned at the right side inwall of the complemental air seal ring on right side and support and the outer wall of right mould and enclose an airtight right cavity, be provided with left air inlet/outlet in the left side wall of support, the end of left air inlet/outlet is extended down to left cavity place, be provided with right air inlet/outlet in the right side wall of support, the end of right air inlet/outlet is extended down to right cavity place.During use, by left air inlet/outlet and right air inlet/outlet place are inflated, make left mould and right mould move to the support center, thereby realize matched moulds, this moment, the space of left cavity and right cavity became large, by the expansion of complemental air seal ring, realized the sealing of cavity surrounding.The complemental air seal ring that uses at present is as O type circle, and due to the restriction of O type coil structures, its compensation range is less, and O type circle is as be in compressive state always, easily deterioration phenomenon occurs and follows the string.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of compensation range greatly and be difficult for aging complemental air seal ring.
For addressing the above problem, the technical solution adopted in the utility model is: the complemental air seal ring, comprise the seal ring body of an annular, and described seal ring body is made by elastic material, the cross section of seal ring body is U-shaped, and its U-shaped mouth is all towards the center of seal ring.
Described seal ring body is made of a base portion and two lobe sections, and two lobe sections are with the symmetrical setting of the central axis of base portion, and under the state of pressurized not, the outer rim of lobe section is the protrusion state with respect to the side of base portion.
The beneficial effects of the utility model are: above-mentioned complemental air seal ring, and it adopts U-shaped cross section, and compensation range is larger, and when being in compressive state, is not prone to deterioration phenomenon always, can guarantee elasticity, has guaranteed the reliability of complemental air.

Embodiment
Below by specific embodiment, the utility model complemental air seal ring is described in further detail.
As shown in Figure 1 and Figure 2, the complemental air seal ring comprises the seal ring body 1 of an annular, and described seal ring body 1 is made by elastic material, and the cross section of seal ring body 1 is U-shaped, and its U-shaped mouth is all towards the center of seal ring.
Described seal ring body 1 is made of a base portion 2 and two lobe sections 3, and two lobe sections 3 are with the symmetrical setting of the central axis of base portion 2, and under the state of pressurized not, the outer rim of lobe section 3 is the protrusion state with respect to the side of base portion 2.
as shown in Figure 3, in use, two above-mentioned complemental air seal rings are separately positioned in the inner left wall and right side inwall of support 4, this moment, seal ring body 1 was subject to the extruding of mould and modification, the outer wall of the complemental air seal ring on the left of being positioned at and the inner left wall of support 4 and left mould 5 encloses an airtight left cavity 6, be positioned at the right side inwall of the complemental air seal ring on right side and support 4 and the outer wall of right mould 7 and enclose an airtight right cavity 8, be provided with left air inlet/outlet 9 in the left side wall of support 4, the end of left air inlet/outlet 9 is extended down to left cavity 6 places, be provided with right air inlet/outlet 10 in the right side wall of support 4, the end of right air inlet/outlet 10 is extended down to right cavity 8 places.During use, by left air inlet/outlet 9 and right air inlet/outlet 10 places are inflated, make left mould 5 and right mould 7 move to support 4 centers, thereby realize matched moulds, this moment state as shown in Figure 4, this moment, the space of left cavity 6 and right cavity 8 became large, seal ring body 1 this moment pressurized no longer, its lobe section 3 expands outwardly and the outer rim of lobe section 3 still fits with the outer wall of mould, realizes the sealing of cavity surrounding.Because above-mentioned complemental air seal ring adopts U-shaped cross section, compensation range is larger, and when being in compressive state, is not prone to deterioration phenomenon always, can guarantee elasticity, has guaranteed the reliability of complemental air.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
