Embodiment Construction

[0007] Below in conjunction with accompanying drawing, invention is described in further detail.

[0008] Such as figure 1 Shown, a kind of device that is used for the movable exhaust of extrusion casting mold, comprises movable mold and fixed mold, and the extruded product that is respectively provided with between movable mold and fixed mold. The overlapping part of the movable mold and the fixed mold is the parting line. There is an exhaust pin on the fixed mold on one side of the extruded product, and a return spring is installed on the exhaust pin. Similar corners.

[0009] In application, after the mold has been produced for a period of time, if the exhaust inside the mold cavity is not smooth, you can use an iron rod to knock on the space at the rear end of the exhaust device, the exhaust pin will move forward, and the sundries in the gap will be removed. The gap is vented with the movement of the vent pin, which then returns to its original position with the return o...

Abstract

The invention discloses a device for movable exhausting of an extrusion casting die. The device comprises a movable die, a fixed die and an extrusion forming product arranged between and on the movable die and the fixed die. The coinciding positions of the movable die and the fixed die are provided with parting lines. An exhaust pin is arranged at the position, on one side of the extrusion forming product, on the fixed die. A reset spring is arranged on the exhaust pin, and the rear end portion of the exhaust pin is provided with an air forcing position communicating with the outside. By means of the device, the problem that gas at partial positions in a cavity is not likely to be exhausted is solved on the basis of not affecting the extrusion casting technology.

Description

technical field [0001] The invention relates to the technical field of mold design and manufacture, in particular to a device for active exhaust of extrusion casting molds. Background technique [0002] Squeeze casting is a forming technology that fills and solidifies liquid or semi-solid metal under high pressure. Due to the simultaneous existence of high pressure solidification and plastic deformation in squeeze casting, the parts have no shrinkage cavity, shrinkage porosity and other defects, the structure is fine and dense, and the mechanical properties are higher than those of die casting and low pressure casting. However, the biggest advantage of squeeze casting is that its products can be processed T6 heat treatment, after T6 heat treatment, its mechanical properties can be greatly improved. Squeeze castings can be heat-treated by T6 because liquid aluminum is filled into the cavity at an ultra-low speed during squeeze casting, which reduces the entrainment of gas in...
