More Information
Summary:The utility model belongs to the technical field of plunger casting, and particularly relates to a chamfering hollow plunger mold and an anti-fracture hollow plunger. The die for the hollow plunger with the chamfer comprises a bottom die, an upper die and a lower die, and the insertion end of the forming core body is provided with a chamfer, so that a corresponding slope surface is formed in the molten iron cooling process after the forming core body is inserted into the molten iron accommodating cavity. The chamfer is formed at the insertion end of the forming core body, so that a corresponding slope surface can be formed in the cooling process of molten iron, the root part of the hollow plunger is reinforced, and the service life of the hollow plunger is prolonged. 本实用新型属于柱塞铸造技术领域，具体涉及一种带倒角空心柱塞模具及防断裂空心柱塞。本带倒角空心柱塞模具，包括：底模，其内部开有铁水容纳腔；成型芯体，其插入端开有倒角，以在插入所述铁水容纳腔后使铁水冷却过程中形成相应坡面。通过在成型芯体的插入端开设倒角，可以使铁水冷却过程中形成相应坡面，对空心柱塞的根部进行加强，延长空心柱塞的使用寿命。
