Door-window group-corner connection profile and glue injection method thereof

Abstract

The invention relates to the field of glue coating processes, in particular to a door-window group-corner connection profile and a glue injection method thereof. Flow guide plates are arranged on the inner side and the outer side of a corner connector. A first glue injection layer and a second glue injection layer are formed on the flow guide plates located on the inner side and the outer side of the profile and the wall of an inner cavity of a profile structure. Four group corner knife points are pressed on a left side plate and a right side plate, all of which are located on the connection end, of a vertical frame and a transverse frame located on the same plane as a first glue injection hole and a second glue injection hole through group corner knifes. Glue is injected into the glue injection layers through the glue injection holes. The angle connector is connected with the profile through the glue injection layers. The uniformity and consistency of smearing of sealant can be guaranteed, and the intensity of group corners is enhanced; it is avoided that water leaks at corners, and the utilization rate of the group corner glue is increased as well; and the door-window group-corner connection profile has the beneficial effects of being good in gluing effect among profiles, easy and convenient to operate and the like.

Description

technical field [0001] The invention relates to the field of gluing technology, in particular to a door and window corner connection profile with high utilization rate of sizing material, good gluing effect between profiles and easy operation and a glue injection method thereof. Background technique [0002] At this stage, the connection method of building exterior door and window products is generally to cut the connection ends of profiles at 45 degrees, and the connection ends of adjacent profiles can also be perpendicular to each other, and the profiles are extruded and connected by corner codes, corner pieces, etc., and adjacent profiles After the section is glued, it is connected.

Problems solved by technology

Due to the characteristics of thermal expansion of metal materials, during the use of aluminum alloy doors and windows, with the change of temperature in different seasons, the profiles will have different degrees of expansion and contraction deformation, resulting in cracking and water seepage at the corners; at the same time, in actual production During the process, when the aluminum profile is assembled with corners, the operator needs to pre-coat a large amount of glue on the end face of the aluminum profile and the cavity, and then insert the corner code into the profile, the utilization rate of the glue in the cavity is low, It causes a lot of waste of rubber, the corners of the group are uneven, and there are obvious dislocations and steps, which not only affects the aesthetics of the product, but also needs to be strengthened.

In addition, because the uniformity and consistency of the glue on the end face of the corner of the aluminum profile cannot be guaranteed when the glue is applied by hand, the assembled product with the corner will leak during use, which seriously affects the service life of the product
