[0050] Example

[0051]For T3, a best-selling model of the French symbol Citroen (PSA) for the global market, this model inherits PSA’s consistent tenet of high safety and high performance, and all indicators of the high safety factor T3 front windshield Very strict, with large arcs on both sides and flat in the middle. General bake-bending molds cannot meet its molding requirements. The present invention can improve this situation well by using the two-time forming and bending mold: when the flat glass is placed on the mold, the movable inner frame is at the lowest point. As the trolley enters the bending furnace, the temperature gradually rises, and the flat glass is due to Under the action of gravity, the glass gradually deforms as the glass is heated. At this time, the middle of the glass is basically completed. When heated to about 500℃, the glass is in a softened state and the molding temperature is the best. At this time, under the action of the ejector, the inner frame ris...

Abstract

The invention discloses a post-forming bent die for the front windshield of a vehicle. The die is composed of an inner frame, an outer frame, a push rod mechanism, an antigravity mechanism and a bottom frame, wherein, the outer frame is connected with the bottom frame into a whole by welding; the antigravity mechanism is connected with the outer frame through a hinge; the push rod mechanism is supported by push rod supporting balls on the bottom frame; and the inner frame drops onto a push rod at the lowest position. The invention has the advantages that the defects of novel products in the prior art, such as long debugging time, large quality fluctuation and unstable quality are overcome; the operation is simple, the repeatability is good, the stability is high, the efficiency is high, the consistency among the glass is good, and the production efficiency is greatly improved; and the rate of spoiled products is reduced, the yield is greatly improved, the cost of production is decreased, and the economic benefits are obvious.

Description

technical field [0001] The invention relates to an automobile windshield mould, which is suitable for the baking and bending of the front windshield of the automobile, and improves the shortcomings of the traditional baking and bending mould. Excellent quality and yield, greatly improving the production efficiency of the front windshield. Background technique [0002] In the past, the front windshield of automobiles was formed by using traditional baking and bending molds. After the temperature was raised in the furnace, it was formed by gravity at one time. The requirements for process parameters, environment, and equipment capabilities were quite high. For the debugging of new products, it often required It takes a long time, the quality fluctuates greatly, and is unstable. Before mass production, it needs to be debugged many times to achieve a stable process state, which affects the development progress of new products and affects production efficiency. Contents of the ...
