Abstract
The invention provides a glass pipe shaping mold, relating to the field of glass pipe production equipment. The mold comprises a cone-frustum-similar mold body, wherein a step hole is formed in the middle of the mold body, a convex platform is arranged at the upper end of the mold body, a platinum layer is coated on the external surface of the mold body, and a platinum wire is extended outwards from the platinum layer. The invention has the characteristics that the platinum layer is coated on the surface of an original glass pipe shaping mold, so that the service life of the mold is greatly prolonged; and the platinum wire is extended from the platinum layer of the mold so that the static electricity on the mold is eliminated, thereby solving the problem of bubble generation caused by static electricity during glass pipe shaping, and improving the product quality.
Description
Technical field:
The present invention relates to the Production of Glass apparatus field, be 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.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of long service life, and can eliminate static, the Glass tubing forming mould that improves the quality of products.
Technical problem to be solved by this invention adopts following technical scheme to realize,
A kind of Glass tubing forming mould comprises the die body of approximate circle frustum, 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 present invention 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 a structural representation of the present invention;
Fig. 2 is a sectional view of the present invention.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with specific embodiment and diagram, further set forth the present invention.
Like Fig. 1, shown in Figure 2, a kind of Glass tubing forming mould comprises the die body 3 of approximate circle frustum; 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 present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
