Glass Products Forming Machine

Abstract

In a glass product forming machine having molds 1A and 1B each composed of a pair of split molds 11 and 12, and a mold cooling device X for cooling the molds 1A and 1B to control the temperatures thereof, in order to prevent the occurrence of a defect such as deformation or cracks in a formed article due to a temperature difference between the split molds 11 and 12, the mold cooling device X is configured to include: cooling mechanisms 3R and 3L provided to the respective split molds, the cooling mechanisms each individually applying cooling air to each of the split molds 11 and 12 of the molds 1A and 1B; valve mechanisms 30R and 30L for individually opening and closing each of paths for introducing cooling air to the respective cooling mechanisms 3R and 3L; temperature detection means for detecting the temperature of at least one of the split molds; and a temperature control device 9 for generating and outputting control signals for controlling the opening and closing operations of the respective valve mechanisms 30R and 30L on the basis of the detected temperature value by the temperature detection means.

Description

technical field [0001] The present invention relates to a glass product forming machine for forming glass products such as bottles, and more particularly, the present invention relates to a glass product forming machine provided with a mold cooling device for controlling the temperature of the mold by applying cooling air to the mold is the target value. Background technique [0002] As a bottle making machine generally called an "IS machine", there is a bottle making machine divided into a plurality of sections (Japanese: セクシヨン), and bottles are formed continuously using molds in each section. The molds installed in each section include: the initial mold (Japanese: coarse type), which introduces a molten glass block called "clot (Japanese: ゴブ)" to form a parison in an intermediate shape; the forming mold (Japanese: Shishang type), which introduces the parison delivered from the initial mold and finally processes the parison into a bottle in the final form. In addition, in...

Problems solved by technology

Bottles formed by molds with inappropriate temperatures have differences in form such as expansion compared with qualified products, and defects such as cracks and wrinkles occur on the bottle
