Abstract

The utility model relates to an X-shaped seal ring mould, wherein the entire mould forms a cylindrical structure; the mould comprises an upper die, a lower die, an inner die, and an outer die, wherein the inner die and the outer die are arranged between the upper die and the lower die; taper bumps are respectively arranged at the insertion ends of the upper die, the lower die, the inner die and the outer die, and an X-shaped ring is formed among the taper bumps. By adopting the scheme disclosed by the utility model, the demoulding and mould cleaning operations are rapider and more convenient by a combined structure design of the upper die, the lower die, the inner die and the outer die; a scrap rubber is not easily generated at the parting part by the structure design of the taper bumps; the precision of the finished product is ensured; and the qualified rate of the product is improved. Thus, the manufacturing cost is reduced.

Description

A kind of X-shaped sealing ring mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of for the manufacture of X-shaped sealing ring mould.

Background technology

The X-shaped sealing ring claims again the star sealing ring, is a kind of both can being installed in for reducing friction in the less groove of special-purpose compression ratio, but also can be used in the same specification O shape circle groove.The X-shaped sealing ring has lower frictional force, can better overcome and reverse, can obtain better to lubricate; Both can be used as the motion potted component that under lower speed, uses, and also be fit to do simultaneously static seal and use; The X-shaped sealing ring mould of prior art is comprised of upper and lower mould, adopts the positioning core axle docking between the upper and lower mould, forms the X-shaped die cavity between the upper and lower mould.Because upper and lower mould adopts the positioning core axle docking, the demoulding, clear mould bother very much, need to insert two mould collar extension places with instrument and pry open, and mold damage has reduced the mold use life-span easily; And the somatotype place of present upper and lower mould easily produces overlap, causes the precision of goods lower, and qualification rate is lower, thereby has increased manufacturing cost.

The utility model content

The utility model purpose is to provide a kind of easy demoulding, clear mould and somatotype place to be difficult for producing overlap in order to overcome the deficiencies in the prior art, guarantees the X-shaped sealing ring mould of goods precision.

For achieving the above object, the technical solution adopted in the utility model is: a kind of X-shaped sealing ring mould, and the cylindrical structure of described mold integral comprises upper die and lower die, internal mold, external mold; Described internal mold, external mold are arranged between patrix and the counterdie; Described upper die and lower die, internal mold, external mold inserted terminal are respectively equipped with tapered protrusion; Form X-shaped circle die cavity between the described tapered protrusion.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

A kind of X-shaped sealing ring mould of the utility model scheme by upper die and lower die, internal mold, the design of external mold fabricated structure, makes the demoulding and clear modulo operation convenient, quick; The structural design of tapered protrusion makes its somatotype place be difficult for producing overlap, guarantees the goods finished product accuracy, improves job efficiency, thereby reduces manufacturing cost.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the structure chart of a kind of X-shaped sealing ring mould of the present utility model;

Wherein: 1, patrix; 2, counterdie; 3, internal mold; 4, external mold; 5, tapered protrusion; 6, X-shaped circle die cavity.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Accompanying drawing 1 is a kind of X-shaped sealing ring mould described in the utility model, and the cylindrical structure of described mold integral comprises patrix 1, counterdie 2, internal mold 3, external mold 4; Described internal mold 3, external mold 4 are arranged between patrix 1 and the counterdie 2; Described patrix 1, counterdie 2, internal mold 3, external mold 4 inserted terminals are respectively equipped with tapered protrusion 5; Form X-shaped circle die cavity 6 between the described tapered protrusion 5.

Below only be 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, all drop within the utility model rights protection scope.

Claims

1. X-shaped sealing ring mould, it is characterized in that: the cylindrical structure of described mold integral comprises upper die and lower die, internal mold, external mold; Described internal mold, external mold are arranged between patrix and the counterdie; Described upper die and lower die, internal mold, external mold inserted terminal are respectively equipped with tapered protrusion; Form X-shaped circle die cavity between the described tapered protrusion.
