Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

A multi-point press forming structure specifically refers to fig. 1 to 4, and comprises an upper heating plate 1 for a hot pressing die, an abutting member 2 moving in a direction perpendicular to the upper heating plate 1, a first driving member 3 driving the abutting member 2 to be in contact with and press the central point of the upper surface of the upper heating plate 1, and second driving members 4 symmetrically installed on two sides of the abutting member 2 and used for abutting against the die.

This kind of repressing forming structure contacts the butt in last hot plate 1 through the descending point of first driving piece 3 drive butt 2, and then to the glass hot pressing in the mould, and drive butt axle 5 descends is installed to 2 both sides of butt, so 5 butt moulds of butt axle of both sides exert the pressure of the same size, have the pressure of balanced mould both sides, guarantee that the level of product both sides is unanimous, improve the product precision and then improve the advantage of product percent of pass.
