Abstract

A glass pressing mold is formed from a split block, a ring, and a punch, with at least one side of the punch flush with the inner wall of the block. In this way, glass products can be formed without some side walls.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass mold for molding glass articles with side walls without at least one side wall.

So far, a mold with a centered punch is used to manufacture glass articles, square or rectangular articles with side walls, including the bottom, whereby after molding the side walls are formed according to the shape and type of article. If a product is required, for example without two side walls, to produce a U-shaped profile, a tetrahedron must be pressed and two walls cut. Due to the appearance and penetration of the light, the cut must be abraded and polished, especially in the case of ornamental glass illuminators. Finishing operations are very costly, despite the possibility of injury.

The disadvantages of the hitherto known methods are eliminated by the press glass mold according to the invention, in which the space for the glass necessary to form the bottom and at least one wall is provided.

The mold is formed by a split block, a ring and a punch, the essence of the invention being that at least one side of the punch is flush with the inner wall of the block.

The top of the side walls of the article is shaped by a removable ring as used in conventional manufacture.

The glass mold according to the invention has the advantage over the prior art in that it is possible to produce glass articles without some side walls in a single operation without the need for further

235 260 processing. The punch is flush with at least one of the side walls of the mold (whereby only the remaining space is formed during molding of the glass filler), thereby forming only some of the walls. In this way, it is possible to produce products with at least one page.

Products manufactured in this way may have adjacent or opposed walls.

The molding die according to the invention is schematically illustrated in the accompanying drawing _of Fig. 1 showing the mold in a front view where the punch is flush with the mold wall, and Fig. 2 shows a cross-sectional side view of the mold.

Pressing glass mold consisting of at least three parts, i.e. a die 4, and a two-part block 2 which is closed by means of pin 5 6 exentrickým key _Z is e.g. formed _from the base plate 1 / including the crown is placed on the plate of the press, not shown. A lock 2 is formed on the base plate 1 including the base 2, which is identical to the lower part of the two-part block g _z serving to connect both parts of the block 1, after its closing. A shoulder 1 is provided on the upper part of the block 2, in which a ring 1 is inserted, which closes the upper part of the block 2 and thus forms the upper edge of the glass article. After the glass has been dispensed into the block 2 by holding the ring 1 with an unmarked center, the two parts are joined and the glass is prevented from escaping from the block 2. only the space between the punch £ and the space in the block 2 «

Pressing glass molds can advantageously be used in shaping hollow square products without at least one wall.
