中文摘要：根据零件的结构，确定了压铸件的分型面，设计了浇注系统；选用的卧式冷室压铸机，进行了压铸模具总体结构设计。该模具用卸料板推出机构的模架，开模后，推杆将卸料板沿分型面推开；通过卸料板推出铸件，受力均衡，不易发生变形。采用了侧向抽芯机构、活动型芯的新型定位方式，保证了孔的位置精度，可生产合格的产品。
英文摘要：According to the structure of oil pump, the parting line of the die castings was determined, the gating system was designed; based on selecting die-casting machine with horizontal cold chamber, the overall structure of die-casting die was designed. Using the stripper plate pushes out the die-frame in the die, after opening the die, the push-bar pushes out the stripper plate along the parting line；the castings were pushed out by the stripper plate, the forcing was balanced, less prone to distortion. Using the side core-pulling mechanism and new orientation style of activity core to ensure the accuracy of hole locations, the qualified products can be produced.
