Double-speed sliding block mechanism

Abstract

The invention discloses a double-speed sliding block mechanism, comprising a support base provided with baffles on two sides, a sliding block capable of sliding on the support base, and a driving block capable of driving the sliding block to move, wherein the driving block comprises a moving head matched with the sliding block in a sliding manner; the end part of the moving head is an included angle end formed by two tangent planes; a baffle can be in surface contact with the sliding block; on a contact surface, the baffles and the sliding block are provided with an unfilled-corner inclined surface respectively so as to form an included angle including the included angle end of the moving head. According to the invention, the driving block capable of driving the sliding block to move comprises a moving head including the two tangent planes; when the driving block moves vertically, the moving head also can move left and right on a horizontal surface by dint of elastic force of an elastic component in a vertical movement procedure; when the moving head moves vertically, the two tangent planes also can make the sliding block process quick double-stroke movement simultaneously and can quickly avoid working pieces which move vertically to a sliding movement direction; and the double-speed sliding block mechanism is suitable to provide quick movement to the sliding block in a plurality of fields.

Description

technical field [0001] The invention relates to a mold, in particular to a fast-moving double-speed slider mechanism. Background technique [0002] Use the mold to fold the workpiece into a shape similar to a U-shaped groove with two folded surfaces, such as figure 1 As shown, the workpiece 1 needs to be lifted and demolded, and the mold must avoid the folded edge 11 of the workpiece. Therefore, a slide block 2 suitable for demoulding is usually arranged in the mold. The slide block 2 includes an inclined surface 21, and the slide block 2 gradually moves toward When avoiding movement in a direction away from the workpiece 1, the inclined surface 21 can avoid the workpiece, so that the workpiece 1 can be lifted and demolded at the same time, which is beneficial to save time. [0003] However, the slider mechanism in the prior art is a single-stroke movement mode, that is, the speed of the slider mechanism is constant. For workpieces with a small bending avoidance distance an...

Problems solved by technology

[0003] However, the slider mechanism in the prior art is a single-stroke movement mode, that is, the speed of the slider mechanism is constant. For workpieces with a small bending avoidance distance and a large avoidance depth, the avoidance of the slider mechanism cannot avoid the rising of the workpiece in time.
