Technical Field

[0001] This utility model relates to the field of product demolding technology, and in particular to a product demolding mechanism with secondary ejection. Background Technology

[0002] The demolding device is an important component of mold design. It is mainly used to smoothly remove the molded product from the mold. The design of the demolding device directly affects the product quality and production efficiency. In the existing technology, the ejector base plate and ejector plate move forward, which drives the ejector pins and angled ejectors to move forward, ejecting the product and causing it to fall out.

[0003] In existing technologies, when ejecting products, they are easily jammed by the angled ejector, preventing them from falling naturally and posing a risk of mold damage. This necessitates manual removal of the jammed product, resulting in longer production cycles, lower efficiency, and increased labor costs. Utility Model Content

When demolding is required, the ejector base plate and ejector panel can be moved downwards, causing the ejector assembly to move through the base and eject the product from the mold groove. If the product is stuck in the mold groove and cannot be moved out, as the ejector base plate moves forward, the lower pressure block moves along the second groove. When the lower pressure block contacts the stop block, the lower pressure block rotates, causing the ejector panel to gradually separate from the ejector base plate, and then causing the ejector assembly to push the product out and disengage from the mold groove. Compared with the prior art, this device, through the design of the lower pressure block and the stop block, can cause the ejector panel to gradually separate from the ejector base plate, causing the ejector assembly to push the product out and disengage from the mold groove, preventing the product from getting stuck, avoiding the inability to demold, reducing the risk of mold pressing, shortening the production cycle, saving labor, and achieving cost reduction and efficiency improvement. It solves the problem in the prior art that when the product is stuck, it needs to be manually removed, which leads to a long production cycle, low efficiency, and increased labor costs.

If the product is stuck in the mold groove 2 and cannot be moved out, as the ejector base plate 6 moves forward, the lower pressure block 10 moves along the second groove 11. After the lower pressure block 10 contacts the stop block 12, the lower pressure block 10 rotates, causing the ejector panel 7 to gradually separate from the ejector base plate 6, and then causing the ejector assembly to push the product out and separate it from the mold groove 2. Compared with the prior art, this device, through the setting of the lower pressure block 10 and the stop block 12, can drive the ejector panel 7 to gradually separate from the ejector base plate 6, drive the ejector assembly to push out the product and separate it from the mold groove 2, prevent the product from getting stuck, avoid the product being unable to be demolded, reduce the risk of mold pressing, shorten the production cycle, save labor, and achieve cost reduction and efficiency improvement. It solves the problem in the prior art that when the product is stuck, it is necessary to manually remove the product, which leads to a long production cycle, low efficiency, and increased labor costs.
