Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an integrated stamping die for automotive parts. Background Technology

[0002] With the rapid development of the automotive industry, the market demand for personalized and diversified automobiles is growing. Automotive parts are generally formed by stamping. Traditional automotive parts stamping dies are mostly single-function designs, meaning that a die can usually only complete one stamping process, such as blanking, bending, and deep drawing. This means that producing a complex automotive part often requires multiple dies to work in sequence. This decentralized production mode has many drawbacks, such as long production cycles. Frequent die changes not only consume time but also require professional technicians, increasing labor costs. Therefore, an integrated automotive parts stamping die is needed.

[0003] Traditional stamping dies can typically only complete one stamping process. In the production of automotive parts, the same part needs to be stamped multiple times, which is time-consuming and labor-intensive, resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an integrated stamping die for automotive parts, in order to solve the problem that the existing stamping dies for automotive parts have relatively limited stamping functions.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated automotive parts stamping die, including a lower die base;

[0006] A cavity mold structure is fixedly installed at the middle position of the top of the lower mold base, and guide posts are fixed at the corner positions of the top of the lower mold base. A movable plate is provided above the lower mold base, and the top of the guide post passes through the movable plate and is fixed to the upper mold base.

[0007] A punch structure is fixedly installed at the middle position of the bottom end of the movable plate;

[0008] The die structure includes a die base fixedly installed at the middle position of the top of the lower die base. The die base has a mold cavity inside. Both sides of the top of the die base have moving grooves. Each moving groove has a return spring inside. Each end of the return spring away from the die base has a pressing block.

[0009] Preferably, the guide post and the movable plate are slidably connected, the upper mold base is located directly above the lower mold base, a mold handle passes through the middle position inside the upper mold base, and the bottom end of the mold handle is fixedly connected to the top end of the movable plate.

[0010] Preferably, the punch structure includes a punch seat, a transmission block, and a punch module. The punch seat is fixedly installed at the middle position of the bottom end of the movable plate. The punch module is fixed at the middle position of the bottom end of the punch seat. Transmission blocks are fixed on both sides of the bottom end of the punch seat.

[0011] Preferably, the main view cross-section of the transmission block is triangular, and the main view cross-section of the convex module is T-shaped.

[0012] Preferably, the interior of the die holders on both sides of the extrusion block is provided with a sliding groove, and the two ends of the sliding groove are provided with a slider.

[0013] Preferably, the top view cross-sectional area of ​​the mold cavity is equal to the bottom end surface area of ​​the convex module, and the concave mold base and the extrusion block form a telescopic structure through a return spring.

[0014] Preferably, one end of the slider extends to the outside of the groove and is fixedly connected to one side of the extrusion block, and the slider and the die holder form a sliding structure through the groove.

[0015] The integrated stamping die for automotive parts provided by this utility model has the following advantages:

[0016] By setting up a die structure, during the stamping process, the metal sheet is subjected to pressure and enters the interior of the die cavity. As the punch continues to press down, the transmission block pushes the extrusion block to move into the interior of the die holder. One end of the extrusion block will extrude the metal sheet and cause secondary deformation. After stamping is completed, as the transmission block moves up, the return spring will pop out the extrusion block, so that the part can move to the outside of the die cavity along with the punch. This realizes the function of facilitating multiple forming, thereby improving the working efficiency in the production of automotive parts.

[0017] By setting up a punch structure, the punch seat drives the punch module to move into the inside of the die cavity. The die cavity will cause the metal sheet to deform inside the die cavity. Under the guiding and squeezing action of the transmission block, it will undergo secondary deformation, thereby improving production efficiency. Attached Figure Description
