Post forming bending mould of automobile front wind screen glass

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 ...

[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 more debugging to achieve a stable process state, which affects the development progress of new products and affects production efficiency.
