However, post-correction is forced correction by external force, which can easily cause damage to the narrow frame. At the same time, the corrected narrow frame is easy to recover after being placed for a period of time.
Moreover, some narrow face frames are too deformed to be corrected

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as Figure 1 to Figure 5 As shown, the deformation control method of the flat panel TV face frame injection molding process of the present invention comprises a face frame body, the face frame body includes an upper edge, a lower edge, a left side and a right side, and each side includes a front panel and a side wall, and the face frame body and Determine the deformed edges compared to the standard part:
[0018] When the deformed side protrudes toward the outer side of its corresponding front panel 1 and / or protrudes toward its opposite side, the thickness S of the side wall 2 corresponding to the deformed side is reduced through mold repair. The above includes three situations: one is that the deformed side protrudes toward the outside of its corresponding front panel 1, for example figure 1 shown; the second is that the deform...

Abstract
The invention discloses a deformation degree control method of a flat-screen television panel injection molding process, which is favorable for controlling the panel deformation degree so as to produce a panel in accordance with design standard. The method comprises the following steps of: comparing a panel body with a standard element and determining a deformed edge; reducing the thickness of a side wall corresponding to the deformed edge by repairing a die when the deformed edge protrudes towards the outer side of a front plate corresponding to the deformed edge and / or protrudes towards an opposite edge; and increasing the thickness of the side wall corresponding to the deformed edge by repairing the die when the deformed edge protrudes towards the inner side of the front plate corresponding to the deformed edge and / or protrudes away from the opposite edge. The deformation degree of a panel is controlled by repairing the die, when the die is changed until the produced panel meets the application requirement, stable and continuous production can be realized, so that the deformation mode of the panel can be controlled better, the finished product rate of the produced panel is obviously improved, and quality is effectively guaranteed.
Description
technical field [0001] The invention relates to the field of molding, in particular to a method for controlling the degree of deformation of the injection molding process of a flat panel TV surface frame. Background technique [0002] In the prior art, when the face frame of a flat-panel TV is produced through an injection molding process, a certain edge of the produced face frame body is often deformed, for example Figure 1 to Figure 4 As shown, the deformed edge protrudes toward the opposite edge, away from the opposite edge, toward the inside of its front panel, or toward the outside of its front panel. The inner side of the front panel is the side where its corresponding side wall is located, such as figure 2 As shown, the deformed side protrudes toward the inner side of the front panel; the outer side of the front panel is the other side opposite to the inner side, as shown in figure 1 As shown in , the deformed edge protrudes toward the outside of the front panel. ...
