Machine blowing molding technology for glass lamp shade

Abstract

The invention relates to a machine blowing molding technology for a glass lamp shade. The process feature lies in the following steps: a, melting frit; b, pre-heating a die to 400-600 DEG C; c, starting up an air compressor to enable compressed air to enter a working system; d, gathering materials in the way that a gatherer picks the cooked frit out of a crucible according to a proper weight and places the cooked frit in the bottom die center of a stamping die of a flat-plate aerostatic press; e, using the flat-plate aerostatic press to press glass cakes; f, forming a semi-finished product through a tread table; g, blowing to form a finished product in the way that a molding worker places a blowing molding die at the opening part of the semi-finished product in a back-off manner, starts up a compressed air switch of the molding tread table to blow the semi-finished product into the finished product and then starts up the blowing molding die; h, annealing in the way that a shade taking worker takes the finished product out of a tread table shaping die and gives the finished product to a shade delivery worker and the shade delivery worker feeds the finished product into an annealing furnace for annealing; and i, drilling in the way that a drilling worker performs drilling on the bottom of a lamp shade. The machine blowing molding technology has the advantages that fire finishing is not required, so that the energy consumption is reduced; counterfeit bubbles are not needed, so that the frit usage rate is high; the production cost is low; and the molding time is shortened.

Description

technical field [0001] The invention relates to a molding technology of a machine-pressed blown glass lampshade, which belongs to the technical field of glass lampshade molding. Background technique [0002] At present, the commonly used production method (prior art) of glass lampshade is the blowing process, which is to start the material with a manual blowing rod, form it in the blowing mold, then stick the bottom to remove the false bubbles of the product, and then burn the mouth and shape it. This production method produces false bubbles, which leads to low glass frit utilization rate; requires burners, consumes more diesel oil; and has high production costs. Contents of the invention [0003] The object of the present invention is to provide a glass lampshade molding process that does not need a burner, saves energy consumption, has no false bubbles, has a high utilization rate of glass frit, and has low production costs. [0004] The technical scheme of the present ...
