Abstract

The utility model discloses a glass tube forming die which relates to the field of production equipment of glass tubes. The glass tube forming die comprises a die body which is similar to a circular truncated cone, wherein a step hole is formed in the middle of the die body, a boss is arranged at the upper end of the die body, a platinum layer is coated on the outer surface of the die body, and a platinum wire outwards extends from the upper surface of the platinum layer. According to the glass tube forming die disclosed by the utility model, the platinum layer is coated on the surface of the original glass tube forming die, so that the service life of the die is greatly prolonged, the platinum wire is led out from the upper surface of the platinum layer of the die, static electricity on the die is eliminated, the generation of bubbles due to the static electricity when the glass tube is formed is further solved, and the product quality is also improved.

Description

A kind of Glass tubing forming mould

Technical field:

The utility model relates to the Production of Glass apparatus field, is specifically related to a kind of Glass tubing forming mould.

Background technology:

Glass is a kind of comparatively transparent solid matter, when fusion, forms the contiguous network structure, and the process of cooling medium viscosity increases and sclerosis and non crystallized silicates non-metallic material gradually.Glasswork is that employing glass is daily necessities or the industrial goods that main raw material processes.

Glass tubing at first drops into the raw material of quartz glass glass sand in the continuous induction melting furnace in the production and the course of processing, and through the electrically heated fusion, the silica glass liquid after the fusion is drawn into large diameter transparent quartz glass tube through forming mould, material platform and tube drawing bench.

In the prior art, the Glass tubing forming mould all adopts alloy material to process, and is shorter following work-ing life in hot environment, and work the time also can produce static, possibly produce bubble when causing the Glass tubing moulding, influences the quality product of Glass tubing.

The utility model content:

The utility model technical problem to be solved is to provide a kind of long service life, and can eliminate static, the Glass tubing forming mould that improves the quality of products.

The utility model technical problem to be solved adopts following technical scheme to realize,

A kind of Glass tubing forming mould comprises the die body of the frustum of a cone, has stepped hole in the middle of the die body; The die body upper end is shaped on boss; It is characterized in that: said die body outside surface is enclosed with the platinum layer, to being projected with a platinum wire, eliminates the static on the mould through platinum wire on the platinum layer.

Said die body adopts the high temperature alloy material to process.

The utility model is parcel one deck platinum on original Glass tubing forming mould surface; Prolong the work-ing life of mould greatly, on mould platinum layer, drawn a platinum wire, eliminated the static on the mould; Thereby produce bubble because of static when having solved the Glass tubing moulding, improved quality product.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the sectional view of the utility model.

Embodiment:

For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.

Like Fig. 1, shown in Figure 2, a kind of Glass tubing forming mould comprises the die body 3 of the frustum of a cone; Die body 3 adopts the high temperature alloy material to process; Have stepped hole 5 in the middle of the die body 3, die body 3 upper ends are shaped on boss 1, and die body 3 outside surfaces have one deck platinum layer 4; On the platinum layer 4 to being projected with a platinum wire 2, the static of eliminating on the moulds through platinum wire 2.

More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

Claims
