Abstract
PURPOSE:To reduce manufacturing man-hour by providing a screw part in the dipping range of a die casting pin in molten casting in a die casting forming, turning the die casting pin and separating from the solidified casting part. CONSTITUTION:The die casting pin 3 providing the screw part 6 is inserted into the die 1 and protruded into the dipping part 5 in the molten casting surrounded with the die 1 and after filling up and solidifying the casting, the die casting pin 3 is constituted by turning this with a rotating device 4 so that this is separated from the casting 2 and can be taken out. Then, before separating the casting 2 from the die 1 after solidifying the casting, the rotating device 4 is rotated in the condition of fixing the position of the casting 2 and the die 1, only the die casting pin 3 is retreated. By this method, after forming the man-hour for screw machining can be reduced.

ダイカストピン。[Claims] 1. In the die-casting technology, a threaded portion is provided in the range where the die-casting pin used to perforate the casting during the forming step is immersed in the casting, the base of the die-casting pin is connected to a rotating device, and the die-casting pin is rotated. A threaded die-cast pin that can be separated from the solidified casting by rotating it. 2. When separating the die-cast pin according to claim 1 from the solidified casting part, a draft angle is provided in the immersed part of the casting in order to reduce the load applied to the die-cast pin due to the clamping force of the solidified and shrunken casting part. Die-cast pin with screw. 3. A threaded die-cast pin according to claims 1 and 2, in which the surface of the cast immersion part is coated with a hard material such as TiC, TiN, or SiC to improve wear resistance. 4. The die-cast pin according to claims 1, 2, and 3 is characterized by using high-speed steel such as SKH57, which has high high-temperature strength and high resistance to breakage, maraging steel, or a material that satisfies these properties. Die-cast pin with screw.
