中文摘要：介绍了实际生产中利用滑块作齿条带动环形齿轮抽出弧形芯的弯管弧形抽芯压铸模，其抽芯机构设计简单、新颖，制造方便，降低了弧形抽芯压铸模的设计难度和制造成本，而且使用方便。
英文摘要：The die-casting die with arch core-pulling mechanism using slide block as rack to drive the ring gear pulling out from the arch core was introduced. The design of the core-pulling mechanism is simple and novel, the core-pulling mechanism is easily manufactured. The core-pulling mechanism makes the design of the die easy and reduces the manufacturing cost of the die. Furthermore, the die is convenient to use.
