Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a combined high-strength automotive front door anti-collision beam molding mold. Background Technology

[0002] The front door anti-collision beam is an important part of the passive safety of automobiles. It is mainly used to absorb and mitigate the impact force of external forces when a vehicle is involved in a collision, so as to reduce the damage to the vehicle and its occupants. In the production of front door anti-collision beams, a molding die is generally used to stamp the anti-collision beams in large quantities. Because the stamping of the anti-collision beam will form a concave structure, the inside of the anti-collision beam will form a semi-closed state, which makes unloading relatively troublesome and requires manual removal of the anti-collision beam from the molding die.

[0003] Chinese Patent Publication No. CN202321409752.4 discloses a molding die for a crash beam. After the crash beam is formed, a motor is activated to drive one of the double-headed screws to rotate. In conjunction with a belt pulley transmission group, the other double-headed screw is driven to rotate synchronously, thereby driving the two supporting base plates on both sides to slide back and forth in the corresponding inner sliding frame. The formed crash beam loses support and automatically and effectively demolds itself by its own gravity, detaching from the inner support mold. However, after long-term use, the inner wall of the mold may wear and deform, requiring the replacement of the entire mold, which is costly.

[0004] Therefore, it is necessary to provide a combined high-strength automotive front door anti-collision beam molding die to solve the above-mentioned technical problems. Utility Model Content

The fixed mold 2 includes a base 201, a U-shaped groove is provided at the top of the base 201, a movable mold 202 is installed inside the U-shaped groove and is adapted to the U-shaped groove, and an ejector template 204 is installed at both the left and right ends of the base 201. The ejector template 204 is detachably connected to the movable mold 202, and a positioning frame 203 is installed at the outer end of the base 201. The inner wall of the positioning frame 203 is provided with symmetrical slots, which are adapted to the ejector template 204 and the movable mold 202.

[0023] The moving mold 3 and the fixed mold 2 are supported by the bracket 1. The car front door anti-collision beam to be stamped is placed on the moving mold 202. The moving mold 3 is operated, and it descends and presses the moving mold 202. The moving mold 202 descends through the ejector plate 204 and cooperates with the fixed mold 2 to stamp the car front door anti-collision beam. The base 201 cooperates with the moving mold 202 to facilitate the stamping of the car front door anti-collision beam by the moving mold 3. At the same time, during the stamping, the car front door anti-collision beam is located inside the positioning frame 203, which can prevent the displacement of the car front door anti-collision beam from affecting the stamping effect. After stamping, the moving mold 3 moves away from the fixed mold 202. When the movable mold 202 is opened, the ejector plate 204 pushes the movable mold 202 upward, causing the stamped front door anti-collision beam to leave the base 201 and positioning frame 203. At this time, a new front door anti-collision beam is pushed onto the movable mold 202. Simultaneously, the previously stamped front door anti-collision beam can be pushed out of the movable mold 202, achieving a rapid demolding effect. The movable mold 202 is connected to the base 201 through the ejector plate 204.
