Abstract

A viscosity optical glass modeling plug of the utility model changes a modeling plane into a curved surface, replaces the cast iron which conducts unevenly and tends to adhere films with aluminum bronze, which solves the problem that fringe is difficult to be controlled and eliminated during the modeling of viscosity optical glass, avoids the disadvantages in the prior art and creates the precondition for the large scale production of viscosity optical glass.

Description

Rare viscosity opticglass moulding plug

The utility model relates to a kind of rare viscosity opticglass moulding plug.

At present, the glass ware forming plug all adopts cast iron planar shaping plug in the opticglass melting field, and this is little to the influence of ordinary optical glass, and single control to rare viscosity glass ware forming striped then is difficult to.Plain cast iron plane plug one be conduct heat inhomogeneous, easy mucous membrane, the 2nd, wash away when excessive, plug moulding striped in plane is difficult to eliminate.In use, the general employing does more glass size, cuts the way of corner by the striped part, leaves and takes remaining salable product.The both sides that inferior measure cuts have sometimes accounted for about half of monolithic glass unexpectedly, and many one cutting actions, both waste materials, effort when good again.

In view of the problem that exists in above-mentioned rare viscosity opticglass production, the purpose of this utility model is a kind of moulding plug that can eliminate the moulding striped to greatest extent of design.

The technical solution of the utility model has reached above-mentioned purpose of design: this rare viscosity glass ware forming plug is characterized in that the contact surface with feed liquid is the smooth surface of indent.After taking this scheme, scouring force is excessive when having solved rare viscosity opticglass and flowing out from leak the material pipe, causes glass ware forming inhomogeneous and produce the problem of striped, makes the quality of rare viscosity moulding opticglass that essential raising arranged.

In order further to improve the good article rate of rare viscosity opticglass, thoroughly overcome the uneven problem of moulding, the utility model is conceived to the selection of plug material.Because it is inhomogeneous that plain cast iron plane plug conducts heat, the generation of striped in the time of can causing moulding equally, thus select for use the good xantal material of heat transfer property to do plug, thus the effect of generation striped when eliminating rare viscosity opticglass moulding further strengthened.

By the design of above-mentioned two aspects, produce the problem of striped when successfully having solved the group of the lanthanides glass ware forming, not only improve the good article rate of rare viscosity opticglass greatly, and solved the key issue of suitability for industrialized production.

Further specify the utility model below in conjunction with accompanying drawing:

Fig. 1 plain cast iron plane plug Fig. 2 xantal curved surface plug Fig. 3 adopts xantal curved surface plug production process synoptic diagram

Among Fig. 3, glass precursor solution flows out from leaking material mouth 2 through leaking material pipe 1, contacts with xantal curved surface plug 3, and uncured glass metal 4 flows forward along bed die 6 and Bian Mo 7, and by the draw hook 9 on traction calculon 8 and the transmission mesh bag to front haulage, forming solidified does not have the rare viscosity opticglass 5 of striped.

It is tapered planes that plain cast iron plug shown in Figure 1 is met material face 10, and during with its traction glass ware forming, it is inhomogeneous to conduct heat, easy mucous membrane, and when rare viscosity glass scouring force was excessive, glass ware forming easily played striped.

Xantal inner sunken face plug shown in Figure 2, meeting material face 10 is inner sunken faces, owing to adopt curvature according to the hydromeehanics design, and adopt the good xantal of heat transfer property to make, make rare viscosity opticglass liquid flow following time, the inner sunken face plug conducts heat evenly, the curvature of its inner sunken face can satisfy the needs that hydromeehanics distributes, produce striped when having avoided glass ware forming, thereby broken through the key that rare viscosity opticglass is produced, improve the product good article rate greatly, successfully solved the difficult problem that rare viscosity opticglass produces striped in producing in batches during moulding.

Claims

1, a kind of sliminess opticglass moulding plug is characterized in that its molding surface is the indent smooth surface.

2, such as claim 1 the moulding plug stated of book, it is characterized in that adopting the xantal material to make.
