The first embodiment is as follows:

a multi-function window hinge mold comprising:

the lower die 1 comprises a bottom plate 11, a vertical plate 12 and a transverse plate 13, wherein the vertical plate 12 is arranged on the side of the bottom plate 11, the transverse plate 13 is arranged above the vertical plate 12, one side of the transverse plate 13, which is far away from the center of the bottom plate 11, is connected with the vertical plate 12, and the bottom plate 11, the vertical plate 12 and the transverse plate 13 enclose a forming groove 14;

the punch 2 is transversely arranged on one side, far away from the vertical plate 12, above the lower die 1, of the punch 2, a bending groove 21 is formed in the lower side of the punch 2, a bending head 22 is arranged on the lower portion, close to the vertical plate 12, of the punch 2, the bending head 22 is matched with the forming groove 14, and the side, far away from the bending head 22, in the bending groove 21 is a first inclined surface 211 which is obliquely arranged;

and the pressing plate 3 is arranged above the bottom plate.

Specifically, before the slide rail workpiece is punched, two sides of the slide rail workpiece are pre-bent into right-angle bent edges, so that the section of the slide rail workpiece is U-shaped. When the die is used for bending the punched slide rail workpiece, the slide rail workpiece is placed on a bottom plate 11, a U-shaped opening of a slide rail is upward, a right vertical part of the slide rail workpiece is abutted against the end surface of a transverse plate 12, a punch 2 and a pressing plate 3 are driven by an oil cylinder, the pressing plate 3 descends to abut against the bottom of the slide rail workpiece, the left side of the pressing plate 3 is attached to the left vertical part of the slide rail workpiece, a bending head 22 is firstly matched with the pressing plate 3 to extrude the upper half part of the left vertical part of the slide rail workpiece to have a rightward bending angle, then the pressing plate moves upwards to withdraw the slide rail workpiece, the punch 2 moves above the slide rail workpiece, an inclined plane I211 is aligned to the left part of the inclined slide rail workpiece, the punch 2 presses downwards, the inclined plane I211 and the upper side surface of a bending groove 21 enable the left side part of the slide rail workpiece to be bent into a right-angle shape, at the moment, the bending head 22 is attached to the inner side surface of the right side part of the slide rail workpiece, the punch 2 moves leftwards, and the bending head 22 is matched with the forming groove 14 to ensure that the right side of the sliding rail workpiece is also bent into a right-angle shape, so that the bending of two side edges of the sliding rail workpiece is completed. Compared with the common die for integrally stamping the sliding rail workpiece, the die directly stamps the side edge of the sliding rail workpiece, and avoids deformation caused by uneven stress at the punching position of the sliding rail workpiece.

Example two:

the difference between the second embodiment and the first embodiment is that the side surface of the bending groove 21 close to the bending head 22 is a second inclined surface 212 which is obliquely arranged.

Specifically, the second inclined surface 212 is arranged, so that the slide rail workpiece can smoothly fall off the punch 2 after the die is punched, the slide rail workpiece rotates around the bending head 22, the second inclined surface 212 does not interfere with the bent part on the left side of the slide rail workpiece, and the slide rail workpiece falls off the punch.

Example three:

the difference between the third embodiment and the first embodiment is that an electromagnet 213 is disposed above the curved groove 21.

Specifically, the material is discharged after punching, when the punch 2 is removed from the lower die 1, the electromagnet 213 is electrified and magnetized, the electromagnet 213 adsorbs the left side of the slide rail workpiece, so that the slide rail workpiece cannot fall off the punch 2, when the punch 2 moves to the position above the blanking position, the electromagnet 213 is powered off and loses magnetism, and the slide rail workpiece falls off the punch and is discharged.

Example four:

the fourth embodiment is different from the first embodiment in that the bottom plate 11 is provided with a stop rod 111 on the side away from the riser 12, and the lower part of the first inclined surface 211 is provided with a through groove 214 matched with the stop rod 111.

Specifically, the position of the slide rail workpiece on the lower die 1 can be limited by the limiting rod 111, and interference between the limiting rod 111 and the punch 2 when the punch 2 moves transversely can be avoided through the groove 214.

Example five:

the difference between the fifth embodiment and the first embodiment is that a reset push rod 121 is arranged in the middle of the vertical plate 12, and the thin air cylinder 15 is connected to the reset push rod 121.

Specifically, after the sliding rail workpiece is subjected to punch forming, the reset push rod 121 is pushed out leftwards by the thin cylinder 15, and the right side of the sliding rail workpiece is separated from the forming groove 14 by matching with the left movement of the punch 2, so that the phenomenon that the sliding rail workpiece is blocked and cannot be discharged is avoided.

What has been described herein is merely a preferred embodiment of the utility model, and the scope of the utility model is not limited thereto. Modifications, additions, or substitutions by those skilled in the art to the specific embodiments described herein are intended to be within the scope of the utility model.
