Abstract

This invention relates to glass forming devices. The purpose of the invention is to increase the service life and utilization rate of the glass mass, as well as to increase the range of diffusers. A detachable form for centrifugal molding, predominantly seamless diffusers, is provided with a disk false. Falsely loosely rests on the bottom of the liner. The bottom parts are cylindrical. It is advisable to falsify in the form of a rolling bearing with a raised pattern on the top. 1 hp f-ly, 3 ill. (L

The invention relates to devices for forming a molten glass by the blower method and can be used for the manufacture of seamless spin-shaped diffusers.

The purpose of the invention is to increase the service life and utilization of glass mass, as well as to increase the range of diffusers.

FIG. Figure 1 shows the device at the moment of blowing the diffuser, a general view; fig. 2 - the same, at the time of removal of the finished product; in fig. 3 shows an embodiment of the device.

The detachable form for glass diffusers contains a plug-in 1, forming a cavity, which are located on horizontal axes x 2, and

howl form (and finally in the throat). bullet glass. The sleeve 8 rises up through the spindle 4 and closes through the spindle 4, through the rim 9, the rim 9 and the hinges 7, Flanger 5, sliding along the turning cylindrical parts of the insert 1, coaxially forming the cavity, closing it from the bottom. The base plate 3 by the spindle 4 is rotated relative to the glass mass bullet fixed by the throat ring 11. Air is blown through the hole in it to force the product. The pellet, swelling, facilitates the sliding walls of the molding cavity, taking its shape. The rotation of the form is terminated. The elements of its structure are shifted in

The latter are fixed on the base plate 20 to the initial initial state, open- | 3, seated on the spindle 4 having the ability to rotate from the drive. The bottom of the cavity is a false-shaped disk 5, resting at the bottom of the cylindrical parts of the inserts 1. At 25 In this case, the radius of the cylindrical part is equal to the distance from the axis 2 to the innermost lower horizontal surface of the liners 1, which are the support of the false-bottom 5. To form products with a relief end, falsely 5 is designed as a support bearing, the upper plate of which EET required drawing, and the bottom is able to rotate relative to the upper. The inserts opening mechanism consists of angles 6, hingedly connected with wells 7, rigidly fixed on hoods 1, and with sleeve 8, having the ability to move back and forth on spindle 4 of support | 3, and also to rotate together with Nim. The rim 9 of the matrix is hinged together for- wards in the midpoints of the angular grids 6 and occasionally (whale for them as a fulcrum. The throat of the diffuser 10 is tightly covered by a detachable throat ring 11 during the molding process.

The form works as follows.

In the initial state, the elements of the configuration of a detachable form are in the following positions. The inserts 1 a wasp x 2 are folded back (the molding cavity is open) with the sleeve B lowered down into ||: the device of tg 6, rim 9 and loops 7. 1 pindle 4 of the base plate 3 sub- ijceH. A ring 11 is fed from above into the open forming cavity of the Orlovina and is preformed in black.

va forming cavity for extracting the finished diffuser 10.

In the second embodiment, the false bottom plate, false plate 5, rotates synchronously with the finishing form in the process of spinning, and the upper plate is fixed, as it is kept from rotation by the throat ring 11 by means of blown glass.

The use of the proposed form for making seamless light diffusers from glass ensures the stability and immobility of the diffuser when the mold is opened, which, in turn, creates conditions for the automatic extraction of the finished product from the forming cavity, a decrease in the twisting. due to the absence of bottom in the bottom of the forming cavity, as well as an increase in the service life in the event of a defect in the bottom of the forming cavity (including due to the eroded seam of the chemically active eklomassoy) due to the rapid replacement of false, and in the well-known will have to change the whole form.

In addition, the introduction of the relief false into the finishing form provides conditions for a fundamentally new direction in the creation of new highly artistic types of seamless diffusers with a relief end. This eliminates the time-consuming operation of trimming the aesthetic cap (bottom) of the diffusers, increases the utilization rate of the glass melt, increases the yield of useful products
