Cylinder driven returning mechanism for side flanging and side reshaping of automobile mold

Abstract

The invention discloses a cylinder driven returning mechanism for side flanging and side reshaping of an automobile mold. The cylinder driven returning mechanism consists of a driving cylinder part and an auxiliary cylinder part, wherein the driving cylinder part comprises a driving cylinder, a clamp ring, a cylinder connector, and two guide cover plates; the driving cylinder is arranged on a lower mold body; the clamp ring is a rectangular block and fixed on the bottom surface of a pulley; the cylinder connector is a convex cylinder with rectangular end surfaces and fixed with the driving cylinder; the auxiliary cylinder comprises two auxiliary cylinders and two inclined wedge guide plates; the two auxiliary cylinders are arranged on the lower mold body; the inclined wedge guide plates, of which the side surfaces are inclined wedge surfaces, are lump; the two inclined wedge guide plates are fixed with the two auxiliary cylinders respectively. The invention has the advantages that: the returning mechanism is driven by a cylinder, driving force provided by an upper mold is not required and all components of the returning mechanism are arranged on the lower mold body, so the components are independent of the upper mold during movement, and manufacturing, processing and debugging are facilitated, and the returning mechanism is simple in structure, low in construction cost, and convenient to apply.

Description

technical field [0001] The invention relates to a return mechanism for shaping the side flanging of an automobile mold, in particular to a cylinder-driven return mechanism for shaping the side flanging of an automobile mold. Background technique [0002] In the shaping and stamping process of the side flanging side of the automobile mold, a return mechanism must be set up. The so-called return trip means that because the profile of the pulley has a negative angle, it is inconvenient to take and place the workpiece after the flanging side is reshaped. Pick and place parts. At present, the flanging side shaping return mechanism used in automobile molds includes a driving leg type return mechanism and a roller type return mechanism. The driving leg type return mechanism realizes the return movement of the pulley through the driving legs placed on the upper mold body and requires the upper mold to provide driving force, but the application of the driving leg return mechanism i...

Problems solved by technology

The driving leg return mechanism realizes the return movement of the block through the driving leg placed on the upper die body and needs the upper die to provide the driving force, but the application of the driving leg return mechanism is limited to the horizontal direction of the return movement of the block. In the non-horizontal direction, multi-stage drives are required, which increases the complexity of the automotive mold structure, and makes processing and debugging difficult, greatly increasing the cost
