Internal conditioning treatment HRC30°±2°
Inclined rods (straight rods) are mainly suitable for large molds. Due to the large difficulty of molding the inclined top of the large mold side and the high cost, it can be divided into diagonal top blocks (straight top blocks) and inclined top bars (straight top bars) for forming, and the screws, pins, and wedges can be used when used. The connection is made by means of tight blocks and the like, and the bottom is equipped with an inclined top slide (the straight top rod is directly assembled to the thimble plate) for forming and ejecting the side core. Due to the fact that the two sides of the inclined top rod are subject to lateral forces, they require high strength and toughness of the top rod. Our top mandrel materials are all made by well-known domestic companies. After internal conditioning, the surface is treated with high frequency and stress relief, which greatly improves the strength, toughness and stability of the products. The mandrel is twice as hot. After several times of grinding, the surface of the ejector rod can reach 0.01mm in size, and can be processed to 1.5m in length. The straightness of 1m is guaranteed within 0.1mm. Common specifications are Φ16, Φ20, Φ25, Φ30, Φ35, Φ40, Φ50. The specific dimensions can be processed according to customer requirements.
