Core-embedded mold facilitating ejection-out of forging

Abstract

The invention relates to a core-embedded mold facilitating ejection-out of a forging. The core-embedded mold facilitating ejection-out of the forging comprises a mold body. A first mold cavity face is arranged on the surface of the mold body. A material ejection-out rod for ejecting out the forging is arranged in the mold body in a movable fit manner. An embedding cavity is formed in the mold body. An embedding core is embedded into the embedding cavity. The surface, exposed from the embedding cavity, of the embedding core is provided with a second mold cavity face. The second mold cavity face and the first mold cavity face are spliced into a preset mold cavity. The embedding cavity is in movable fit with the embedding core. The embedding core is located on the ejection-out path of the material ejection-out rod. The end, close to the ejection-out end of the material ejection-out rod, of the embedding core is smaller than the opposite end in size. The embedding core is formed by splicing at least two embedding core sections, and a splicing seam is matched with the second mold cavity face in shape. By the adoption of the core-embedded mold, the embedding core can be ejected out by the material ejection-out rod along with the forging, the embedding core can be easily separated along the splicing seam after being disengaged from the embedding cavity, the forging is subject to demolding smoothly, and damage and production interruption caused by the fact that the mold is stuck by the forging can be avoided.

Description

technical field [0001] The invention relates to a forging die, in particular to a core-embedded die which facilitates ejection of forgings and demoulding. Background technique [0002] The forging process can be divided into die forging and free forging, in which die forging is to squeeze and deform the blank in the cavity of the mold to obtain the required forging shape. [0003] After the forging is deformed in the die cavity, it needs to be demolded. The current molds are usually equipped with ejection mechanisms for demoulding. For example, in the mold, there is an ejector hole, and a sliding-fit ejector rod is arranged in the ejector hole, and a cam mechanism or a hydraulic device is used to push the ejector rod to eject the forging from the cavity. [0004] The above-mentioned demolding method is suitable for most forgings, but for some long-sized high-ribbed and thin-walled parts, because the ribs are deeply embedded in the mold cavity, the bonding force is strong, a...

Problems solved by technology

[0004] The above-mentioned demolding method is suitable for most forgings, but for some long-sized high-ribbed and thin-walled parts, because the ribs are deeply embedded in the mold cavity, the bonding force is strong, and the forging has a long extension distance. For demoulding, the middle part of the forging is often lifted by the ejector rod, and the two ends of the forging are still stuck in the mold, which leads to deformation and damage of the forging, and it takes a lot of time to clean the mold, resulting in a decrease in the efficiency of the enterprise
