Problems solved by technology

[0004] At present, there are many drawing dies used for auto parts that have roughening phenomenon in mass production, which leads to cracking, dark cracking and wrinkling during parts production, high scrap rate, and may also cause parts with dark cracks to fail due to lack of inspection. Installed on the automobile assembly, resulting in the scrapping of the whole body and affecting the quality image of the product

Embodiment Construction

[0039] refer to Figure 1 to Figure 10 Further explanation of the automotive side wall forming mold.

[0040] A car side wall forming mold, such as figure 1 , figure 2 and Figure 10 As shown, it includes base 1, front pressing core 2, side pressing core 3, fixed mold pressing core 4 fixedly arranged on base 1, fixedly arranged on base 1 and used to drive side pressing core 3 to tilt downward The first drive assembly 5 moving towards the direction of the fixed die pressing core 4 and the second drive assembly 6 arranged on the base 1 for driving the front pressing core 2 to slide in the direction of the front pressing core 2 on the base 1; When the core 4, the side binder core 3 and the front binder core 2 are closed, a shaping cavity 7 for drawing and forming the side wall is formed, and the side binder core 3 and the front binder core 2 are set to be equal in length, and the fixed mold is pressed. The length of the material core 4 is longer than that of the side pressur...

Abstract

The invention discloses a side body forming mould for an automobile. The mould comprises a base, a front surface material pressing core, a side surface material pressing core, a fixed mould material pressing core fixedly arranged on the base, a first driving assembly arranged on the base and connected to the side surface material pressing core and a second driving assembly connected to the front surface material pressing core. The fixed mould material pressing core, the side surface material pressing core and the front surface material pressing core are closed to form a setting cavity which draws and forms the side body, the side surface material pressing core is slidably arranged on the base, a limiting piece for limiting the side surface material pressing core to slide toward the front surface material pressing core is arranged on the base, and a guiding assembly for guiding the side surface material pressing core to slide on the base is further arranged between the base and the side surface material pressing core; the side body is compressed and drawn on the fixed mould material pressing core by virtue of the side surface material pressing core, and is then further drawn by virtue of the front surface material pressing core, so that the mould has an effect of improving the forming quality of an automobile part.

Description

technical field [0001] The present invention relates to auto parts forming equipment, more specifically, it relates to an automobile side wall forming mold. Background technique [0002] The side wall is the main component of the car frame and an important structural component in terms of car safety performance. It mainly plays the role of carrying, supporting, protecting and installing side doors in the car body; stamping die is an important link in car production At present, body stamping parts are mainly realized by cold stamping. The forming process mainly includes drawing, trimming, flanging, shaping and other work contents. The drawing die is usually composed of three major parts: punch, die, and blank holder. Partial composition, during stamping production, the ejector rod of the machine tool acts on the blank holder to lift it up, and then the upper die and the blank holder press the blank together and move downward for drawing forming. [0003] Drawing is a process...
