Embodiment Construction

[0024] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0025] Refer to attached figure 1 , 2 , the internal corner structure of the groove is extruded by the slit die at one time, and the inner part of the traditional corner is dug out. As shown in the accompanying drawing (2), the inner rubber strip at the corner is dug out, and then the The corner mold is filled with materials to fill the excavated inner rubber strips, and the corners are formed and bent. In this way, the R corner of the trough conforms to the change of the sheet metal surface of the side door, and the cloak of the cloak fits the sheet metal better, so as to achieve the structure and function in use.

[0026] It can be seen from the accompanying drawings that the traditional joint angle is the figure 1 The front section (1) of the middle woolen groove and the upper sect...

Abstract

The invention relates to a method for producing an internal connection angle of an automobile slot and a slot internal connection angle structure produced by the same. The method comprises the following steps of: performing one-time extrusion molding on a slot piece by using a first die, wherein the slot piece comprises a slot front section, a slot upper section and a connection angle part which is arranged between the slot front section and the slot upper section; digging out the inside part of the connection angle part; and putting the slot piece after the inside part is dug out into a second die to perform molding and bending treatment of the connection angle part; and forming the slot internal connection angle structure after the treatment.

Description

technical field [0001] The invention relates to a window frame sealing device of a vehicle, in particular to a method for producing an inner corner of an automobile woolen groove and the inner angle structure of the woolen groove produced therefor. Background technique [0002] In the prior art, the sealing strip structure used for the guide groove of the automobile window frame is molded by hot rubber injection molding, and there are obvious corner indentations at the corner joints, and the material difference is obvious. Moreover, it is easy to deform during installation and use, has poor appearance, and poor consistency of finished products. Contents of the invention [0003] The object of the present invention is to provide a method for producing the inner corner of the automobile furnish and the inner corner structure of the woolen groove produced, so that the manufacturing cost of the existing corner can be reduced, the qualified rate of the product can be improved, ...
