Technical Field

[0001] The utility model belongs to the technical field of lock tongue processing, and relates to a lock tongue processing mold, in particular to a pressing molding mold for lock tongue processing. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping and other methods. They mainly realize the processing of the shape of the object by changing the physical state of the molded material. The lock tongue on the car seat belt is often processed by pressing iron sheets through molds. The stamping die is a process equipment that processes metal iron sheets into lock tongues during stamping.

[0003] After searching, it is found that a Chinese patent document discloses a special lock tongue processing mold for refrigerators [Application No.: CN202222174234.0; Publication No.: CN218535287U]. This tongue processing mold is composed of a connecting rod, a connecting bolt, a translation threaded rod and a clamping rod. After the clamping rod is clamped with the connecting bolt, the translation threaded rod can drive the movable mold to translate to one side.

[0004] The patent discloses that the connecting rod is used to prevent the lifted movable mold from hindering the removal of the molded items in the fixed mold. However, when the mold is used to press the lock tongue, it cannot achieve efficient stamping of metal materials, has poor accuracy, and requires external auxiliary devices to perform active stamping on the movable mold, which is complicated to operate and affects the processing efficiency of the lock tongue.

Both sides are slidably connected with side panels 5, and the inner sides of the two groups of side panels 5 are provided with slide grooves, and the inner walls of the slide grooves are slidably connected with sliders, and the sliders are fixedly connected to the left and right sides of the upper seat plate 4. By arranging sliders on both sides of the upper seat plate 4, under the sliding action of the sliders and the slide grooves, the upper seat plate 4 can be stably and balanced between the two groups of side panels 5, ensuring the accuracy and activity effect of the upper seat plate 4 driving the bottom stamping die 3. At the same time, the side panels 5 are fixedly installed on the surface of the bottom plate 1, so that the two groups of side panels 5 and the bottom plate 1 are fixed as a whole;

[0035] A top plate 6 is fixedly connected to the top of the two groups of side plates 5, and movable plates 7 are provided on both the left and right sides of the top plate 6, and the bottom end of the movable plate 7 is fixedly connected to the upper seat plate 4, and two groups of movable plates 7 are provided in parallel on the surface of the upper seat plate 4, and the movable plates 7 are vertically distributed with the upper seat plate 4, and the upper seat plate 4 is parallel to the bottom plate 1. Through such a structural setting, the two groups of movable plates 7 can drive the upper seat plate 4 to move in a balanced manner, and ensure the accuracy of the upper seat plate 4 moving up and down;

[0036] like Figure 1-Figure 4 As shown;

[0037] Considering the moving effect of the movable plate 7, a rack 8 is fixedly connected to the inner wall of one side of the movable plate 7, and the inner wall of the rack 8 is meshed with a gear 9, and the gear 9 is fixedly installed on the outer wall of the rotating rod 14. Under the action of the two groups of movable plates 7, two groups of gears 9 are correspondingly arranged. By synchronously arranging the two groups of gears 9 on the outside of the rotating rod 14, the rotating rod 14 can synchronously drive the two groups of parallel gears 9 to rotate synchronously, thereby realizing the stable lifting and lowering of the two groups of movable plates 7. Specifically, considering the working effect of the rotating rod 14, the rotating rod 14 is rotatably connected to the inside of the two groups of side plates 5 through bearings, and the rotating rod 14 The outer end is fixedly connected with an operating disk 15, and the operating disk 15 is arranged outside the side plate 5.

[0039] like Figure 1-Figure 4 As shown;

[0040] Four groups of fixed rods 16 are fixedly connected to the surface of the base plate 1. Specifically, the fixed rods 16 are arranged around the fixed mold 2. A guide rod 17 is telescopically arranged inside the fixed rod 16. A telescopic spring is embedded between the fixed rod 16 and the guide rod 17 to ensure the telescopic effect of the guide rod 17 inside the fixed rod 16.
