Abstract

The invention discloses a method and system for acquiring the positional relation of a crank arm injection molding machine thrust seat and a movable template. An articulated mechanism model is established according to a crank arm articulated mechanism of a crank arm injection molding machine, wherein the articulated mechanism model consists of a first connecting rod, a second connecting rod and atriangular member capable of rotating around a first vertex of itself, and the positional relation of the thrust seat and the movable template can be acquired according to the lengths of all components and the mutual angular relationship as well as the angle and spacing relation of horizontal and vertical lines. According to the positional relation, the movement characteristics of the thrust seatcan be acquired, and conversion of the positions of the thrust seat and the movable template under different states can be realized, high precision and rapid adjustment can be realized, thus improvingthe product control precision, shortening the debugging time, simplifying the operation and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of crank arm injection molding machines, in particular to a method and system for obtaining the positional relationship between a thrust seat and a movable platen of a crank arm injection molding machine. Background technique [0002] The crank arm hinge structure of the crank arm injection molding machine can make the force on the mold more even and increase the mold opening stroke, thereby improving the low pressure protection of the mold. Among them, the crank arm hinge mechanism (such as figure 1 As shown), it is mainly composed of oil cylinder 1, short connecting elbow 2, long connecting elbow 3, movable template 4, fixed template 5, cross connecting elbow and horizontal top plate. The whole shape is similar to a human arm, and the long connecting elbow 3 is connected to the dynamic Formwork 4, the horizontal top plate is connected to the piston of the oil cylinder. When the oil cylinder 1 stretches, i...
