AI Technical Summary
Existing stamping dies are prone to tilting or jamming when the ejector plate moves, which affects the normal ejection of stamped parts and may cause surface scratches.
A hydraulic lifting rod is used to push the mounting plate, which in turn drives the upper push cylinder in the demolding assembly to lift the stamped part under the action of the contraction spring. Combined with the servo motor driving the connecting rod, the material is pushed out, ensuring uniform force during the demolding process. Hard springs and rubber top blocks are used to improve stability.
It improves the stability and reliability of demolding, reduces production interruptions, and increases production efficiency and product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping die that facilitates material cutting. Background Technology
[0002] Stamping dies are special tools used in stamping processes. Mounted on a press, they utilize the pressure applied by the press to separate or deform sheet metal or strip within the die cavity or between the dies, thereby obtaining parts with the desired shape, size, and properties. The structure and precision of stamping dies directly affect the quality and production efficiency of stamped parts, and they are widely used in industrial production, such as in the automotive, home appliance, and electronics industries.
[0003] A search revealed an existing patent (publication number: CN222268421U) that discloses a stamping die for easy material unloading. An upper die is fixedly connected to the telescopic end of a hydraulic cylinder, and a material-pushing mechanism is connected to the lower die for easy unloading. The material-pushing mechanism includes connecting rods. A first groove is formed at the upper end of the lower die, and connecting rods are slidably inserted into both sides of the first groove. A push plate is fixedly connected to one end of each connecting rod, and a fixing block is fixedly connected to the other end of each connecting rod. A spring is fixedly connected to each fixing block, and one end of each spring is fixedly connected to the lower die. This invention, after stamping, uses a hydraulic cylinder to move the upper die upwards to reset. After the upper die separates from the stamped part, the spring force causes the fixing blocks to move upwards to reset. The fixing blocks push the push plate upwards via connecting rods, and the push plate pushes the stamped part upwards, causing the push plate to move upwards to reset. This misaligns the stamped part with the lower die, facilitating the removal of the stamped part.
[0004] The push plate and the fixed block are connected by a connecting rod, and the spring force is used to reset and push the stamped part. However, in actual operation, the spring force is difficult to be uniform, and the sliding of the connecting rod is also prone to being unsmooth. This may cause the push plate to tilt or get stuck when it moves, affecting the normal ejection of the stamped part, and may even scratch the surface of the stamped part. Utility Model Content
