Abstract

The invention discloses an extrusion casting device. The extrusion casting device comprises a support. A lower die is arranged on the inner side of the support. An upper die is arranged on the top ofthe lower die. First springs are arranged at the bottom of the lower die. A bottom plate is arranged at the bottoms of the first springs. Lower clamping rods are arranged on the outer sides of the first springs. Upper clamping rods are arranged on the tops of the lower clamping rods. Protruding rods are arranged at the bottom of the bottom plate. Support blocks are arranged on the two sides of thetop of the bottom plate. Pull frames are arranged on one sides of the support blocks. Moving devices are arranged on the inner sides of the pull frames. A connecting device is arranged on the top ofthe upper die. A telescopic rod is arranged on the top of the connecting device. Through the arrangement of the moving devices, an air cylinder works and drives the telescopic rod and the upper die tomove downwards, accordingly, the upper die and the lower die achieve the object extrusion effect, and after extrusion is complete, rotation rods are rotated and then drive movable blocks to move downwards through support plates, the movable blocks pull the support blocks to disengage from the lower die through the pull frames, the lower die pressure reduction effect is achieved, accordingly, thelower die is protected, and lower die damage is avoided.

Description

technical field [0001] The invention relates to the technical field of casting molding, in particular to a squeeze casting device. Background technique [0002] Squeeze casting, also known as liquid die forging, is to inject molten metal or semi-solid alloy directly into the open mold, and then close the mold to generate filling flow to reach the outer shape of the workpiece, and then apply high pressure to make the solidified The metal (shell) undergoes plastic deformation, the unsolidified metal is subjected to isostatic pressure, and high-pressure solidification occurs at the same time, and finally the method of obtaining the workpiece or blank. [0003] When extrusion casting an object, it is necessary to protect the casting mold, because excessive pressure will cause damage to the mold, thereby damaging the casting object. [0004] Therefore, it is necessary to invent a squeeze casting device to solve the above problems. Contents of the invention [0005] The object...
