[0004] However, the above device still has the following problems during implementation:

[0005] For example, the forging mold currently used for automobile headlight brackets is not convenient for punching holes during die-casting of the brackets. The brackets need to be disassembled and installed on another set of molds before punching holes, which affects the production efficiency of the automobile headlight brackets and increases their production costs. Utility Model Content

[0006] The purpose of the utility model is to provide a molding die for an automobile headlight bracket to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For example, see Figure 1-5 , the utility model provides a technical solution:

[0027] The automobile headlight bracket forming mold comprises a frame 9, a hydraulic cylinder 1 is fixedly connected to the top of the frame 9, and the output shaft of the hydraulic cylinder 1 passes through the top of the frame 9 and is fixedly connected to a pressing plate 2, a plurality of punching columns 3 are fixedly connected to the bottom of the pressing plate 2, and a punching mechanism 4 is arranged on the outer wall of the punching column 3;

[0028] Further, the punching mechanism 4 includes an upper mold 401, and a first through hole 408 is opened in the upper mold 401 at a position corresponding to the punch column 3, a second slide groove 403 is opened in the upper mold 401, and the inner walls on both sides of the second slide groove 403 are slidably connected to the limit rod 404, and a circular groove 301 is opened on the outer wall of the punch column 3, and a plurality of grooves 407 are opened on the side corresponding to the circular groove 301 where the two limit rods 404 are close to each other;

[0029] More specifically, in this embodiment, the sheet is placed in the processing area of ​​the lower mold 6, and the pressure plate 2 is pressed down by the output of the hydraulic cylinder 1. At this time, the pressure plate 2 will slide downward in contact with the outer wall of the slide rod 5, ensuring that the pressure plate 2 will not deviate while pressing down. Because the limiting rod 404 slides in the circular groove 301 to limit the punch column 3, the pressure plate 2 will drive the stamping mechanism 4 to press down synchronously through the punch column 3. After the stamping mechanism 4 is pressed down to a certain position, the sheet can be stamped. Then, when the stamping mechanism 4 continues to descend, the inclined surface set on the side rod 405 makes the side rod 405 slide into the first slide groove 402, and at the same time drives the limiting rod 404 in the second slide groove 40 3, after sliding to a certain position, the groove 407 will correspond to the first through hole 408, and the punching mechanism 4 will no longer continue to press down, and the punching column 3 will no longer be limited and continue to press down to complete the punching of the sheet, and the waste sheet dropped by the punching will fall out of the waste hole 10. After the punching is completed, the output shaft of the hydraulic cylinder 1 is used to shrink, which drives the punching column 3 to move upward. When the circular groove 301 corresponds to the second sliding groove 403, the limiting rod 404 will slide outward due to the compression force of the first spring 406. At this time, the side wall of the limiting rod 404 will slide to the inner wall of the circular groove 301, realizing the limiting effect of the punching column 3, so that the punching column 3 will drive the stamping mechanism 4 to move upward synchronously.

[0030] Embodiment 2:

[0031] On the basis of the above embodiment, the pressing plate 2 is slidably connected to a slide bar 5, and the bottom of the slide bar 5 is fixedly connected to a lower mold 6, an inner groove 601 is provided inside the lower mold 6, and a material taking mechanism 8 is provided on the inner wall of the inner groove 601;

[0032] Further, the material taking mechanism 8 includes a rotary rod 801, and one end of the rotary rod 801 is rotatably connected to the inner wall of the inner groove 601, one end of the outer wall of the rotary rod 801 is fixedly connected to a gear 802, the bottom of the inner groove 601 is fixedly connected to a second spring 804, and the top of the second spring 804 is fixedly connected to a tooth block 803, the tooth block 803 is provided with a tooth groove on one side facing the gear 802, and the inner wall of the tooth groove of the tooth block 803 is meshed and matched with the gear teeth of the gear 802, and the other end of the rotary rod 801 is fixedly connected to a knob 805;

[0033] More specifically, in this embodiment, after the punching and forming of the sheet is completed, the sheet will be pressed and adhered to the surface of the lower mold 6 due to the punching, and it may be difficult to take it out. At this time, the rotating knob 805 drives the gear 802 to rotate through the rotating rod 801. The gear 802 drives the tooth block 803 to press downward when rotating. When the smooth surface of the gear 802 rotates to a side close to the tooth block 803, the tooth block 803 will pop up due to the compression force of the second spring 804, so that the sheet The bottom is loosened and easy to remove due to the force of the tooth block 803, which prevents the sheet from being squeezed and attached to the surface of the lower mold 6 and difficult to remove. The knob 805 is continued to be rotated to compress the tooth block 803 into the inner groove 601 to complete the contraction of the tooth block 803. The rubber ring 806 is arranged to squeeze and fit the inner wall of the lower mold 6, and a damping effect is generated due to friction, which prevents the tooth block 803 from popping up due to the compression force of the second spring 804 after the knob 805 is released.

[0034] Working principle: place the sheet into the processing area of ​​the lower mold 6, and drive the pressure plate 2 to press down through the output of the hydraulic cylinder 1. At this time, the pressure plate 2 will slide downward in accordance with the outer wall of the slide rod 5, ensuring that the pressure plate 2 will not deviate while pressing down. Because the limit rod 404 slides in the circular groove 301 to limit the punch column 3, the pressure plate 2 will drive the stamping mechanism 4 to press down synchronously through the punch column 3. After the stamping mechanism 4 is pressed down to a certain position, the stamping of the sheet can be achieved. Then, when the stamping mechanism 4 continues to descend, the inclined surface set by the side rod 405 makes the side rod 405 slide into the first slide groove 402, and at the same time drives the limit rod 404 to slide in the second slide groove 403. After sliding to a certain position, the groove 407 will correspond to the first through hole 408. At this time, the stamping mechanism 4 will no longer continue to press down, and the punch column 3 is no longer limited and continues to press down to complete the punching of the sheet, thereby completing the punching and forming process of the sheet.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
