In this embodiment, the present invention provides a male mold slanted ejecting block demolding mechanism 100 for ejecting a product 10, which includes:
the core insert 110 is disposed in a core mold, and the core insert 110 has a first groove;
a first wear-resistant block 120 disposed in the first recess of the core insert 110;
the inclined ejecting block 130 is arranged above the core insert 110, a plurality of inclined holes 131 and a plurality of through holes 132 are arranged in the inclined ejecting block 130, and the friction loss between the inclined ejecting block 130 and the core insert 110 is reduced through the first wear-resistant block 120, so that the service life of the inclined ejecting block 130 is prolonged;
a plurality of locking members 140 respectively disposed in the plurality of through holes 132 in the lifter block 130, the plurality of locking members 140 respectively moving in the plurality of through holes 132;
the tops of the ejector rods 150 respectively penetrate through the core insert 110 and the first wear-resistant block 120 and abut against the bottoms of the locking pieces 140, the locking pieces 140 respectively lock the tops of the ejector rods 150 and the inclined ejector block 130 together, and when the inclined ejector block 130 is worn and needs to be replaced, the purpose of quickly replacing the inclined ejector block 130 can be achieved by disassembling the locking pieces 140;
a plurality of inclined guide posts 160 respectively disposed in the inclined holes 131 of the inclined top block 130, wherein bottoms of the inclined guide posts 160 are fixedly disposed on the core insert 110, and an inclination angle is formed between the inclined guide posts 160 and the core insert 110, so that the inclined top block 130 can be inclined along the inclined guide posts 160 by the inclination angle, and the product 10 can be demolded;
the second wear-resistant block 170 is arranged on one side of the slanted ejecting block 130, and the slanted ejecting block 130 reduces the friction loss with a male die through the second wear-resistant block 170, so that the service life of the slanted ejecting block 130 is prolonged.
