Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for automotive parts. Background Technology

[0002] Automotive parts stamping dies are specialized process equipment used for the mass production of automotive metal parts with high efficiency. Their core principle is to use a powerful press to force metal sheets (such as steel sheets and aluminum sheets) to undergo plastic deformation or separation within a precisely designed die cavity, thereby obtaining parts with the required shape, size and performance.

[0003] In the existing technology, the stamping process for automotive parts is relatively cumbersome, which affects the stamping efficiency for workers.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN222659898U) discloses an automotive parts stamping die. This automotive parts stamping die includes: a fixed base; a support component disposed on the fixed base; a stamping component disposed on the support component; an upper die disposed on the support component; a lower die fixedly connected to the top of the fixed base by bolts; and a positioning mechanism. The positioning mechanism includes a power component and two sets of adjusting components, each set of adjusting components being disposed on the fixed base, and the power component being disposed on both the adjusting components and the fixed base. This automotive parts stamping die, through the rotation of a fixed motor driving a fixed bevel gear to rotate, can cause two threaded rods to rotate via transmission. The two positioning plates can be moved by the limiting rods, thereby limiting the stamping material. Fine-tuning can be made according to the size of the material, increasing the accuracy of the stamping.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, after the stamping of automotive parts, the formed parts fall into the mold groove. Removing the automotive parts that have fallen into the mold groove is cumbersome and not conducive to the workers taking out the stamped parts. Utility Model Content

[0006] The purpose of this utility model is to provide a stamping die for automotive parts, so as to solve the problem mentioned in the background art that after the automotive parts are stamped, the formed parts fall into the mold groove, and it is cumbersome to take out the automotive parts that have fallen into the mold groove, which is not conducive to the workers taking out the stamped parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for automotive parts, including a lower die and an upper die correspondingly disposed on the upper end of the lower die, wherein the upper end of the upper die is bolted to the power output end, the lower die is provided with a demolding mechanism for ejecting automotive parts, and sleeves are fixedly installed at the four corners of the lower die, and positioning rods are sleeved inside the sleeves, wherein the upper end of the positioning rods is fixedly installed on the lower end of the upper die, and an auxiliary release mechanism is provided between the positioning rods and the sleeves.

[0008] Furthermore, the demolding mechanism is provided with a bonding plate, the outer side of which is bonded to the inner wall of the upper groove of the lower mold, and the lower end of the bonding plate penetrates through the lower mold. A lifting plate is fixedly installed at the lower end of the bonding plate.

[0009] Furthermore, the outer side of the lifting plate is attached to the inner wall of the lower mold, and a return spring is provided at the lower end of the lifting plate, with the lower end of the return spring fixedly installed inside the lower mold.

[0010] Furthermore, a damper is provided inside the lower mold, and the upper end of the damper is fixedly installed on the lower end of the lifting plate. An opening groove is provided on the surface of the lower mold, and the upper end of the opening groove is inclined. A traction rope is inserted through the opening groove, and the upper end of the traction rope is fixedly installed on the lower end of the upper mold. The lower end of the traction rope is fixedly installed on the upper end of the lifting plate.

[0011] Furthermore, the auxiliary disengagement mechanism is provided with a piston ring, and the upper end of the piston ring is fixedly installed on the lower end of the positioning rod. The upper end of the sleeve is provided with a sealing sleeve, and the inner side of the sealing sleeve is in contact with the surface of the positioning rod.

[0012] Furthermore, the upper inner side of the sleeve is connected to a guide pipe, and the lower end of the guide pipe is connected to the mold groove of the lower mold, and the upper end of the guide pipe corresponds to the lower end of the bonding plate.

[0013] Furthermore, the outer side of the sleeve is connected to a one-way air inlet, and a one-way valve is provided inside the one-way air inlet, and the one-way air inlet is located above the piston ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. When the upper mold descends to stamp, the positioning rod slides along the inside of the sleeve to position it. The stamped car parts fall into the product groove at the upper end of the lower mold, causing the positioning rod to retract into the product groove inside the lower mold. After the upper mold finishes stamping, the traction rope is pulled to slide along the inside of the opening groove and pull the lifting plate, causing the lifting plate to rise and drive the bonding plate to rise along the inside of the product groove, thereby causing the stamped car parts to detach from the product groove, thus achieving the effect of easy demolding. Furthermore, as the upper mold descends, the traction rope is pulled and retracted into the inclined position at the upper end of the opening slot to avoid the traction rope being damaged by the stamping.

[0015] 2. When the positioning rod rises, it can further improve the demolding effect with the assistance of airflow while pushing the product upward and detaching, thus promoting demolding efficiency. This allows the gas to pass through the gap between the positioning rod and the product groove, pushing the automotive parts and improving the demolding effect. Furthermore, when the upper mold descends for stamping, the positioning rod and piston ring descend and draw air through the one-way air inlet. The one-way valve inside the one-way air inlet allows air to enter but not exit, thus enabling repeated use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As Figure 1 - Figure 4 The technical solution shown is a stamping die for automotive parts. To solve the problem of inconvenient demolding and removal of automotive parts, it discloses: a lower die 1 and an upper die 2 correspondingly arranged on the upper end of the lower die 1, with the upper end of the upper die 2 bolted to the power output end 3; a demolding mechanism for ejecting automotive parts is provided inside the lower die 1; sleeves 4 are fixedly installed at the four corners of the lower die 1, and positioning rods 5 are sleeved inside the sleeves 4; the upper end of the positioning rods 5 is fixedly installed on the lower end of the upper die 2; the demolding mechanism is provided with a bonding plate 9, the outer side of the bonding plate 9 is bonded to the inner wall of the upper groove of the lower die 1, and the lower end of the bonding plate 9 penetrates through the lower die 1. The lower end of the bonding plate 9 is fixedly installed with a lifting plate 6. The outer side of the lifting plate 6 is attached to the inner wall of the lower mold 1. The lower end of the lifting plate 6 is provided with a return spring 8, and the lower end of the return spring 8 is fixedly installed inside the lower mold 1. The lower mold 1 is provided with a damper 7, and the upper end of the damper 7 is fixedly installed at the lower end of the lifting plate 6. The surface of the lower mold 1 is provided with an opening groove 10, and the upper end of the opening groove 10 is inclined. A traction rope 11 is passed through the opening groove 10, and the upper end of the traction rope 11 is fixedly installed at the lower end of the upper mold 2. The lower end of the traction rope 11 is fixedly installed at the upper end of the lifting plate 6.

[0026] The upper die 2 is lowered by the power output terminal 3 to stamp the automotive part stamping material placed on the lower die 1, such as... Figure 1 and Figure 2 As shown, when the upper die 2 descends for stamping, the positioning rod 5 slides along the inside of the sleeve 4 for positioning. Then... Figure 3 As shown, when the upper mold 2 descends to stamp, the stamped automotive parts fall into the product groove at the upper end of the lower mold 1, and the descending mold presses down the bonding plate 9, causing the bonding plate 9 to descend and push the lifting plate 6 to descend. Simultaneously, the descending lifting plate 6 presses down the return spring 8. Through the damper 7, the return spring 8 is prevented from reciprocating, causing the positioning rod 5 to retract into the product groove inside the lower mold 1. After the upper mold 2 finishes stamping, as the power output end 3 rises, it pulls the traction rope 11. The traction rope 11 is pulled to slide along the opening groove 10 and pull the lifting plate 6, causing the lifting plate 6 to rise and drive the bonding plate 9 to rise along the product groove, thus removing the stamped automotive parts from the product groove. This achieves convenient demolding. Meanwhile, as... Figure 4 As shown, as the upper mold 2 descends, the traction rope 11 is pulled and retracted into the inclined position at the upper end of the opening groove 10 to avoid the traction rope 11 being crushed by the punch.

[0027] Example 2: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of excessive demolding pressure easily damaging automotive parts: an auxiliary release mechanism is provided between the positioning rod 5 and the sleeve 4. The auxiliary release mechanism is equipped with a piston ring 12, and the upper end of the piston ring 12 is fixedly installed on the lower end of the positioning rod 5. A sealing sleeve 13 is provided on the upper end of the sleeve 4, and the inner side of the sealing sleeve 13 is attached to the surface of the positioning rod 5. A guide pipe 14 is connected to the inner side of the upper end of the sleeve 4, and the lower end of the guide pipe 14 is connected to the mold groove of the lower mold 1. The upper end of the guide pipe 14 corresponds to the lower end of the bonding plate 9. A one-way air inlet 15 is connected to the outer side of the sleeve 4, and a one-way valve is provided inside the one-way air inlet 15. The one-way air inlet 15 is located above the piston ring 12.

[0028] After the positioning rod 5 is inserted into the sleeve 4, when the upper mold 2 rises, the upper mold 2 drives the positioning rod 5 to rise. When the positioning rod 5 rises, it adheres to the inner wall of the sleeve 4 through the piston ring 12. When the piston ring 12 rises, as... Figure 6 As shown, under the action of the sealing sleeve 13, the piston ring 12 rises and compresses the air inside the sleeve 4, causing the air inside the sleeve 4 to be sent into the guide pipe 14, as... Figure 7 As shown, the air entering the guide pipe 14 is sent into the product slot, so that when the positioning rod 5 pushes the product to rise and detach, it can further improve the demolding effect with the assistance of the airflow, and promote the demolding efficiency. The gas passes through the gap between the positioning rod 5 and the product slot to push the automotive parts and improve the demolding effect. At the same time, when the upper mold 2 descends for stamping, the positioning rod 5 and the piston ring 12 descend and draw air through the one-way air inlet 15. The one-way valve set inside the one-way air inlet 15 makes the one-way air inlet 15 only able to take in air and not out air, so that it can be used repeatedly.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
