具有典型内螺纹铸件的压铸模设计

Design of Die Casting Mold with Inner Screw Thread

压铸模设计过程中,具有内螺纹铸件的脱模一直是设计难点。针对该问题,设计了一种斜滑块内置的脱模机构。探究压铸工艺,对模具结构进行设计;分析了模具的工作机制,给出了主要的压铸工艺参数。实际生产表明,该模具生产稳定,工件成型品质高。

When designing the die casting mold, the demould is difficult to castings which with inner screw thread. To solve this problem, a demould mechanism with inner inclined sliding block was developed, and the die casting process was explored thoroughly to design the structure of mold; the mold working mechanism was analyzed, and the main die casting parameters were given. Actual production show that the mold is stably and reliably, the products get high quality.
