The term "a" should not be understood as a limitation on the quantity. Embodiment

[0032] Please refer to Figures 1-4 , a forming die for the lower section of an automotive inner panel, comprising: an upper die 1 and a lower die 101. The upper die 1 and the lower die 101 are buckled with each other, and the two are buckled with each other to form a complete die cavity. A blanking plate 102 is arranged on one side of the lower die 101 for conveying and taking out parts after the die is opened. Its working process is that during the injection molding or stamping process, the upper die 1 and the lower die 101 are buckled with each other to form a closed cavity. The raw material is injected or pressed into the cavity through an injection molding machine or a stamping machine. After a certain holding pressure and cooling time, the part is formed. Subsequently, the die is opened, and the part is taken out through the blanking plate 102;

[0033] Furthermore, a forming die for the lower section of an automotive inner panel further comprises: a fixed shaft 2. The fixed shaft 2 is symmetrically arranged at the top of the blanking plate 102. A buffer assembly is rotatably connected to the fixed shaft 2 for buffering the blanking of materials on the blanking plate 102. The fixed shaft 2 is symmetrically arranged at the top of the blanking plate 102. This layout helps to maintain the stability and symmetry of the die, ensuring that the materials are evenly stressed during the blanking process. Through the buffering effect, it can also protect the materials from being damaged during the blanking process, ensuring the quality of the finished product;

[0034] Even further, a forming die for the lower section of an automotive inner panel further comprises: a fixed seat 3. The fixed seat 3 is arranged on the lower die 101. A downward pressing assembly linked to the buffer assembly is arranged on the fixed seat 3. The burrs on the outer surface of the die can be scraped off during the downward pressing process by the downward pressing assembly, which can automatically complete the burr cleaning work during the production process, avoiding the quality problems caused by burrs on the outer surface of the formed part when the dies are squeezed and collided with each other.

[0035] Among them, both the upper die 1 and the lower die 101 are provided with bottom plates, which are located on the opposite sides of the upper die 1 and the lower die 101. The fixed seat 3 is fixedly arranged on the bottom plate of the lower die 101. A conveyor belt 103 for intermittently conveying materials is further arranged on the bottom plate of the lower die 101. Partition blocks 104 are evenly and equidistantly arranged on the conveyor belt 103. The partition blocks 104 evenly and equidistantly arranged on the conveyor belt 103 play a role in positioning and separating materials. The partition blocks 104 ensure that each material can maintain a fixed position and spacing during the conveying process, which not only facilitates the accurate blanking of materials, but also helps to improve the consistency and quality stability of the finished product.

[0036] It should be noted that the buffer assembly includes a swing rod 201 and a torsion spring 202. The swing rod 201 is symmetrically and rotatably connected to the outer surface of the fixed shaft 2. A torsion spring 202 is sleeved in the middle of the fixed shaft 2. The two ends of the torsion spring 202 are respectively limited on the swing rod 201. When the workpiece is discharged through the blanking plate 102, the gravity factor will squeeze the swing rod 201, causing the swing rod 201 to gradually tend to be parallel to the side wall of the blanking plate 102. The torsion force of the torsion spring 202 is less than the gravity of the workpiece when it falls, so as to avoid the obstruction of the workpiece falling. By setting two groups of buffer assemblies to buffer the workpiece blanking process, during the rotation of the swing rod 201, the torsion spring 202 begins to release the energy it stores and generates a resistance to the rotation of the swing rod 201. This resistance opposes the gravity of the workpiece when it falls, thereby slowing down the falling speed of the workpiece and realizing the buffering of the blanking process. Since the torsion force of the torsion spring 202 is designed to be less than the gravity of the workpiece when it falls, the workpiece can fall smoothly without being blocked, and at the same time, the damage to the mold caused by excessive impact is avoided.

[0037] It is worth mentioning that a contact point one 203 is provided on the swing rod 201 on the side close to the conveyor belt 103. The contact point one 203 is electrically connected to a contact point two 204. The contact point two 204 is located on the side wall of the blanking plate 102. After the contact point one 203 and the contact point two 204 are electrically connected, they control the opening and closing of the pressing component. When the workpiece is transported above the blanking plate 102 and starts to fall, its gravity will squeeze the swing rod 201, causing the swing rod 201 to rotate around the fixed shaft 2. As the swing rod 201 rotates, the contact point one 203 gradually approaches the contact point two 204. When the workpiece is transported to a certain position and the swing rod 201 rotates to a sufficient angle, the contact point one 203 contacts the contact point two 204 to form an electrical connection. The electrical connection will trigger a signal, and this signal is transmitted to the control unit of the pressing component through the circuit. After receiving the signal, the control unit will start the pressing component to work. At this time, the pressing component starts to press down to scrape off the burrs on the outer surface of the mold.

[0038] It should be noted that the pressing component includes a connecting rod 301, and the connecting rod 301 is fixedly arranged on the fixed seat 3. A fixing plate 302 is arranged on the connecting rod 301, and a gear 303 is rotatably connected to the fixing plate 302. The pressing component further includes a sliding rod 304, and the sliding rod 304 is slidably arranged through the connecting rod 301. A plurality of teeth 305 are arranged on the sliding rod 304, and the teeth 305 are meshed with the gear 303. A pressing block 308 is arranged at the bottom end of the sliding rod 304, and the pressing block 308 can be adjusted according to the shape of the workpiece. When the swing rod 201 rotates to a sufficient angle and the contact point one 203 contacts the contact point two 204 to form an electrical connection, the gear 303 starts to rotate and drives the sliding rod 304 to slide downwards, so that the pressing block 308 at the bottom of the sliding rod 304 squeezes and removes the burrs on the outer surface of the workpiece on the conveyor belt 103.

[0039] Wherein, an elastic member 306 and a limiting block 307 are sleeved on the outer surface of the sliding rod 304. The elastic member 306 is located below the connecting rod 301 and its end is fixedly connected to the connecting rod 301. The limiting block 307 is located below the elastic member 306 and is fixedly connected to the sliding rod 304. When there is no external force, the sliding rod 304 is kept at a higher position under the action of the elastic member 306. At this time, the pressing block 308 is kept at a certain distance from the workpiece on the conveyor belt 103. As the gear 303 rotates, its tooth part meshes with the tooth 305 on the sliding rod 304, pushing the sliding rod 304 to slide downward along the connecting rod 301. During this process, the pressing block 308 at the bottom end of the sliding rod 304 gradually approaches and contacts the outer surface of the workpiece. After the deburring operation is completed, the control unit stops driving the gear 303 to rotate. At this time, the elastic member 306 starts to function, pushing the sliding rod 304 to slide upward along the connecting rod 301 to reset, preparing for the next pressing action.
