Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a forming blanking mold for processing a power battery case cover. Background Art

[0002] A mold is a tool used to make molded objects. It mainly realizes the processing of the object's appearance by changing the physical state of the molded material. Under the action of external force, the blank is made into a product with a specific shape and size. In industrial production, there are molds such as injection molding, blow molding, extrusion, die casting and forging. The production of some physical products requires die casting molds. In the prior art, most traditional die casting molds are just a female mold and a male mold that squeeze each other to fill the mold chamber between the two molds with materials. After cooling, the material solidifies and the production is completed. Since it is produced by inlaying and extruding the material, the material is often embedded in the female mold after extrusion. When discharging the material, it is necessary to manually pry the material out of the mold slot. Due to the short cold extraction time, the material is not completely cooled and has a certain flexibility, which is easy to cause damage to the material when prying.

[0003] To this end, a forming mold with announcement number "CN210877481U" is provided, which is convenient for unloading, including a mold base, both sides of the mold base are fixedly connected with sliding rods, the tops of the two sliding rods are fixedly connected with support plates, a male mold is fixedly connected between the two support plates, a female mold is provided between the male mold and the mold base, both ends of the female mold are fixedly connected with sliding blocks, the two sliding blocks are respectively slidably connected to the two sliding rods, the two sliding blocks are located between the sliding rods and the female mold and are threadedly connected with screw rods, the bottom of the screw rod is fixedly connected with a limiting block, a removable discharge top plate is provided at the bottom of the mold groove of the female mold, which can be removed after the mold is stamped, and the formed material can be taken away from the mold groove, which can quickly unload the material and improve the production efficiency, one side of the discharge top plate is connected to the outside of the male mold by a connecting rope, and when the female mold descends, the discharge top plate is pulled out of the mold groove by the connecting rope to complete the discharge, without the need to pry out the material, which is convenient and quick.

[0004] However, for the above-mentioned forming mold which is easy to unload, although the female mold descends, when the connecting rope is stretched to the limit, the slide plate is pulled to pull the material of the discharge top plate out of the mold groove to facilitate unloading, there are still the following obvious defects during use: when the female mold unloads the material by pulling the discharge top plate through the connecting rope, the discharge top plate is suspended in the air because of the inertia of the upward pull, which will cause the discharge plate to tilt under the swing of the connecting rope, causing the molded part to fall.
