Abstract

The utility model relates to a toughening forming die for automotive glass, comprising a forming ring; the forming ring comprises a forming ring body (1) and a stainless steel fiber belt that is wrapped on the forming ring body (1); the forming ring body (1) is provided with a die surface (10) that is contacted with a piece of glass; a plurality of air holes (101) are arranged in the die surface; and the air holes (101) are through holes. In the toughening forming die for the automotive glass, as the plurality of air holes are arranged in the die surface of the forming ring body, the top and the bottom of the forming ring are breathable. As the die surface does not have gaps and is smoothly transitioned, the upper surface and the lower surface of the glass can be uniformly quenched, the stress difference is not generated, and the quality and the safety of the automotive glass can be improved.

Description

A kind of automobile glass changes into type die

Technical field

The utility model relates to the vehicle glass processing mold, more particularly, relates to a kind of automobile glass and changes into type die.

Background technology

Tempered glass of automobile is a kind of shatter proof glass, and it is a kind of prestressed glass in fact, forms stress at glass surface, at first offsets skin stress when glass bears external force, thereby has improved supporting capacity, reinforcing glass self anti-wind pressure, cold and heat property, impact etc.As depicted in figs. 1 and 2, for existing a kind of automobile glass changes into type die, the softening back of glass relies on self gravitation moulding on the moulding ring of mould; The moulding ring comprises moulding ring body 1, is coated with stainless (steel) wire and Stainless Steel Fibre band on the moulding ring body 1 successively, is provided with a plurality of U-shaped breach 11 in the inboard of moulding ring body 1; Form mould tooth 12 between the U-shaped breach, this kind structure causes moulding ring full communication between the higher and lower levels property poor, and mould tooth 12 causes stress concentration easily; In vehicle glass moulding quenching process; Cause down stress distribution on glass inhomogeneous easily, very easily damaged in the polishing test, and have the hidden danger of self-destruction.

The utility model content

The technical problem that the utility model will solve is, changes into the above-mentioned defective of type die to the automobile glass of prior art, provides a kind of automobile glass to change into type die, can not produce stress-difference when making automobile glass change into type.

The utility model solves the technical scheme that its technical problem adopted: construct a kind of automobile glass and change into type die; Comprise the moulding ring; Said moulding ring comprises moulding ring body, and is coated on the Stainless Steel Fibre band on the moulding ring body, and said moulding ring body has the die face with glass contact; Said die face is distributed with a plurality of breather holes, and said breather hole is a through hole.

Change in the type die at the described automobile glass of the utility model, said breather hole is distributed on the inboard of said moulding ring body.

Change in the type die at the described automobile glass of the utility model, the diameter of said a plurality of breather holes is identical.

Change in the type die at the described automobile glass of the utility model, the diameter of said a plurality of breather holes is different.

Change in the type die at the described automobile glass of the utility model, said breather hole is circular hole or elliptical aperture.

Change in the type die at the described automobile glass of the utility model, said breather hole is a polygonal hole.

The automobile glass of implementing the utility model changes into type die, and have following beneficial effect: the automobile glass at the utility model changes in the type die, because the die face of moulding ring body is provided with a plurality of breather holes; Make the moulding ring ventilative up and down; Because there is not breach in die face, transitions smooth can be avoided lower surface on glass uniform quenching up and down when moulding; Can not produce stress-difference, improve the quality and the security of vehicle glass.And make burning glass have wave to produce, in the polishing process of the test, anti-pressure ability is high, can effectively avoid glass in installation process because of the self-destruction that causes under improper or the external force effect is installed.

Description of drawings

To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:

Fig. 1 is the synoptic diagram that the automobile glass of prior art changes into the moulding ring body of type die;

Fig. 2 is an A portion enlarged view among Fig. 1;

Fig. 3 is the synoptic diagram that the automobile glass of the utility model changes into moulding ring body in the preferred embodiment of type die;

Fig. 4 is a B portion enlarged view among Fig. 3.

Embodiment

Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the embodiment that accompanying drawing specifies the utility model at present.

Like Fig. 3 and shown in Figure 4; Change into the synoptic diagram of the moulding ring body in the preferred embodiment of type die for the automobile glass of the utility model; This automobile glass changes into type die and comprises a moulding ring, and wherein the moulding ring comprises moulding ring body 1, and is coated on the Stainless Steel Fibre band (for illustrating) on the moulding ring body 1; This Stainless Steel Fibre band is conventional Stainless Steel Fibre band, is formed by the Stainless Steel Fibre braiding.Referring to Fig. 3 and Fig. 4, moulding ring body 1 has the die face 10 with glass contact, and die face 10 distributes by a plurality of breather holes 101; Breather hole 101 is a through hole, gathers on die face 10, when glass ware forming quenches; Moulding ring body 1 is ventilative up and down, avoids like this producing stress-difference owing to temperature head causes lower surface on glass, because die face 10 still is the plane on the whole; Transitions smooth can avoid occurring stress concentration.Because moulding ring body 1 and glassy phase contact part mainly are positioned at the inboard of moulding ring body 1, so breather hole 101 also is distributed in the inboard of moulding ring body 1 accordingly.

In the present embodiment, the diameter of breather hole 101 is unsuitable excessive, and the diameter of breather hole 101 can be identical, also can be inequality.The shape of breather hole 101 can be various, for example can be circular, oval or Polygons, is advisable with easy to process.

Automobile glass at the utility model changes in the type die; Because the die face of moulding ring body is provided with a plurality of breather holes, make the moulding ring ventilative up and down, because there is not breach in die face; Transitions smooth; Can avoid lower surface on glass uniform quenching up and down when moulding, can not produce stress-difference, improve the quality and the security of vehicle glass.And make burning glass have wave to produce, in the polishing process of the test, anti-pressure ability is high, can effectively avoid glass in installation process because of the self-destruction that causes under improper or the external force effect is installed.

Combine accompanying drawing that the embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the utility model.
