[CN 201820575676.7] Multi-extrusion head extrusion casting die frame for single-action hydraulic press


[CN 201820575676.7] Title of multi-extrusion head extrusion casting die frame for single-acting hydraulic press: Application number of multi-extrusion head extrusion casting die frame for single-acting hydraulic press: CN 201820575676.7 Applicant: Guangdong Hongte Precision Technology Zhaoqing Co., Ltd. Application Date: 2018-4-20 Patent Type: Utility Model The utility model discloses a multi-extrusion head casting die frame for single-acting hydraulic press, the upper formwork, which moves linearly up and down with the movable beam of the single-acting hydraulic extruder, is fixed on the bottom surface of the movable beam of the single-acting hydraulic press through the connecting frame. The upper surface of the upper die connecting plate is equipped with a backing plate, the backing plate is equipped with an upper seat top plate, the center of the upper seat top plate is fixedly equipped with a unloading oil cylinder, and a number of extrusion pressure oil cylinders corresponding to the hot joint positions are distributed around the unloading cylinder. The utility model specially designs a multi-extrusion head extrusion casting mold frame for a single-action hydraulic press, which realizes the secondary local extrusion of the single-action hydraulic press at multiple positions in the vertical direction. The casting defects such as shrinkage porosity and shrinkage cavity of complex castings are effectively eliminated, and the finished product rate and quality of castings are improved. The utility model has a simple and reasonable structure, reliable operation, easy control and easy application in the industry.
