Rapid mold opening and closing expansion system

Abstract

The invention provides a rapid energy-saving and high-efficiency die opening and closing expansion system. The expansion system comprises an alloy steel seat, wherein one ends of a second crankshaft and a first crankshaft are separately in rotating connection with the alloy steel seat; a die closing cylinder is located in the central position of the back surface of the alloy steel seat; a die closing rod is arranged in the die closing cylinder, penetrates through the alloy steel seat, and is fixedly connected with the first crankshaft through a connecting block; the other end of the first crankshaft is fixedly connected with a rotating shaft on a base through a first connecting rod; the base is located between the alloy steel seat and a movable die plate and is close to the movable die plate; the two ends of the rotating shaft are connected with the second crankshaft through vertical rods; and the second crankshaft is fixedly connected with the movable die plate through a second connecting rod. By omitting the traditional two-step locating and assembly of the movable die plate, the alloy steel seat, a high bracket and a low bracket, the high bracket, the low bracket and the die plate are directly combined into a whole in the casting process, the assembly is simple, the tolerance is zero, and the failure is zero. At the same time, the expansion system is compact in structure, stable in action, low in energy consumption, great in rigidity and great in reliability.

Description

[0001] Technical field: [0002] The invention relates to the technical field of die-casting machines, in particular to a rapid mold opening and closing expansion system. [0003] Background technique: [0004] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form it, and obtain solid metal castings after the mold is opened. It was originally used for die-casting characters. With the advancement of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, die-casting technology has developed extremely rapidly. [0005] The opening and closing mold expansion system is an important part that determines the performance of the die-casting product of the die-casting machine. At present, the traditional die-casting machine basically adopts the steel belt type and high and low support mold ope...

AI Technical Summary

Problems solved by technology

[0007] What the present invention aims to solve is that the opening and closing speed of the traditional die-casting machine is slow, and it is easy to cause problems such as broken shafts, broken green columns, broken steel sleeves, broken elbows, and broken templates during the operation of the machine.
