Abstract

The invention relates to the manufacture of a molding tool for the production of glass containers on rotary type machines with air cooling. SUMMARY OF THE INVENTION: The mold comprises a housing placed in a housing. The body is made with longitudinal ribs on the outer side surface. The annular rib is located at a distance of 1 / 3-1 / 2 of the height of the body from its bottom. Diffusers for air supply are installed in the casing at the level of the annular rib. 2 hp f-ly, 1 ill.

Description

The invention relates to building materials, in particular, to equipment for glass engineering, and can be used in the manufacture of a molding tool for the production of glass containers on rotary machines with air cooling.

The aim of the invention is to increase productivity and improve the quality of glassware by intensifying cooling and creating an isothermal temperature range on the working surface of the mold.

The drawing shows a mold for making glassware. The body of the form 1 with the ring edge 2 and the longitudinal edges 3 is located in the casing 4. The ring edge 2 is located in the middle part of the body at a distance (h) (1 / 3-1 / 2) ero height. The shape of the profile of the rib is made in the form of an involute, which is coupled with a hull with a radius r of fillet equal to 1 / 2-1 / 3 of the height of the rib. The longitudinal ribs 3 are located around the entire circumference of the body of the form, and their number is taken depending on the diameter of glassware and the amount of heat removed (four, six, eight).

The longitudinal ribs 3 are located from the annular ribs at a distance of 1.5-2.0 heights of the annular ribs. The height of the annular and longitudinal ribs is assumed to be the same. In the casing 4, at the height of the annular rib, two diffusers 5 are installed symmetrically relative to the shape. The casing 4 is made, for example, of sheet steel, and the housing 1 is made of high-strength cast iron or alloyed steel.

During operation, the cooling fan air from the cooling column nozzles (not shown) flows through the diffusers 5 into the cavity of the casing 4 and the annular edge 2 is distributed into the channels between the longitudinal edges along the shape up and down. Due to the adopted design arrangement of the edges and the proposed configuration of the annular rib, the cooling air is evenly distributed over the entire surface of the housing. This allows the mold body to be more efficiently cooled and to obtain isothermal

Claims (3)

Example. The shape has a height of 267 mm. The ring rib is located at a height of 133.5 mm from the bottom of the form. The height of the annular and longitudinal ribs - 12 mm; the number of longitudinal ribs is 8. The radius of the fillet is 4 mm {1/3 of the height of the annular rib). The ribs © of the rib are located from the middle of the annular rib at a distance of 13.5 mm (1.13 of the height of the annular rib). Claims 1. Form for making glassware. containing a detachable housing with an annular edge on the outer side surface and diffusers for inlet 0 five air, characterized in that, in order to increase productivity and improve the quality of glassware due to the intensification of cooling and create an isothermal temperature range on the working surface of the mold, the body is made with longitudinal ribs on the outer side surface and the annular edge is located at a distance of 1/3 -1/2 of the height of the body from its bottom. 2. The form according to claim 1, characterized in that it is made with a casing. 3. Form on PP. 1 and 2, differing in that the diffusers for air supply are installed in the casing at the level of the annular npfir.
