Metal pressure casting die swing hook dual-division swage die mechanism

Abstract

A metal pressure casting die swing hook dual-division swage die mechanism comprises a die fixed clamping plate, a fixed die plate, a moving die plate, a moving die base plate, a moving clamping plate, a push plate arranged inside the die and a venting pin, a swing hook (6) is movably connected onto the outer side face of the fixed die plate(4) through screws, a pulling hook (7) is fastened onto the outer side face of the fixed clamping plate (5), a limited block (2) is fastened onto the outer side face of the moving die plate (11), the swing hook (6) and the limited block (2) are in buckled fitting, and a roller on the swing hook (6) and a roller on the pulling hook (7) are in sliding fitting. The action of the swing hook and the action of the pulling hook are adopted in the die, so that when the die is opened, a sprue of a gating system is automatically cut off, the problem that a sprue cannot be cut off automatically in a metal pressure casting die is solved, meanwhile, the design is optimized, it is achieved that the structure is simple, the sprue is cut off by utilizing the time of die opening, clotted materials fall out of the die as a result of the self weight, the motion is firm and reliable, and the demoulding is conducted smoothly.

Description

technical field [0001] The invention relates to metal die-casting molding, which is a metal die-casting mold pendulum hook double-parting mold mechanism. Background technique [0002] Metal die-casting mold is a mold composed of metal parts with different functions. It consists of two parts to allow the casting to be removed from the cavity after cooling. The molten metal fills the cavity through runners, sprues, and gates, and exhausts gas through overflow exhaust. In die casting, the pressure generally acting on the metal is in the range of 20-200MPa, the initial filling speed is 0.570m / s, and the filling time is only 0.01-0.03s. The filling and solidification methods of die casting make it have the following advantages. It can pressurize castings with complex shapes. The castings have high precision, stable size, good consistency, less machining allowance, smooth surface, dense casting structure and good mechanical properties. At present, there are many structural typ...

Problems solved by technology

Therefore, the gate of the casting and the gate of the gating system cannot be automatically cut off in the mold. At the same time, the material at the junction of the gate and the casting is thick, which is not easy to cut outside the mold. In addition, after cutting, there is a large gap on the surface of the casting. Removal marks, which affect the appearance of the casting
