Description

Technical Field

[0001] The present application relates to a lever pendulum block propulsion mechanism. Background Art

[0002] In automatic machines or mold equipment, it is often necessary to convert movement in one direction into movement in another direction, such as converting vertical movement into horizontal movement, in order to achieve certain special actuation requirements. The conventional design is to use a vertical punch that moves in the vertical direction and a horizontal punch that moves in the horizontal direction. The vertical punch contacts the inclined surface on the corresponding horizontal punch through an inclined surface, thereby converting the vertical movement into horizontal movement. However, in this conversion method, the displacement of the vertical punch and the displacement of the horizontal punch are converted equidistantly, and the horizontal punch cannot be designed with a larger stroke. Otherwise, the volume of the vertical punch or the horizontal punch needs to be designed to be very large, which will increase the volume and weight of the entire equipment, and the cost will also increase, which needs to be improved.
