Description

Automobile door mold and use method

Technical Field

The invention relates to the field of automobile molds, in particular to an automobile door mold and a using method thereof.

Background

The vehicle door provides a passage for a driver and passengers to enter and exit the vehicle, isolates the interference outside the vehicle, reduces side impact to a certain extent, and protects the passengers. The aesthetic appearance of an automobile is also related to the shape of the door. The quality of the vehicle door is mainly characterized by the anti-collision performance of the vehicle door, the sealing performance of the vehicle door, the opening and closing convenience of the vehicle door, and other indexes of using functions. The anti-collision performance is particularly important, because the buffer distance is short when the vehicle collides laterally, and people in the vehicle are easily injured.

In the prior art, when the automobile door is demolded, because the molded automobile door panel frame is weaker, the frame is clamped and fastened, if the automobile door panel is ejected too fast to be damaged easily during demolding, if the demolding direction is introduced to cause uneven force when manual demolding is adopted, the frame structure can be damaged to a certain extent, and thus the whole automobile door panel is influenced in anti-collision performance when in use, and therefore, the demolding mechanism adopting a proper force is very important.
