Abstract

The invention discloses a hydraulic type mould pressure system. The hydraulic type mould pressure system comprises an upper mould base and a lower mould base; a hydraulic rod and a cooperatively used piston rod are arranged between the upper mould base and the lower mould base; a hydraulic mechanism is arranged below the upper mould base; transmission air cylinders are symmetrically arranged below the hydraulic mechanism; each transmission air cylinder is connected with a synchronous module; a mould punch is arranged on the synchronous module; a material popping device connected with the hydraulic mechanism is arranged at the middle part of each mould punch; a lower mould used cooperatively with the mould punch is arranged on the lower mould base. The hydraulic type mould pressure system is simple in structure, realizes constant, adjustable and quantitative management of pressure, simplifies the mould adjusting difficulty, and meets the actual use requirement.

Description

technical field [0001] The invention relates to a hydraulic mold pressure system, which belongs to the technical field of mold pressure systems. Background technique [0002] There are many stamping products of auto parts drawing, and the shape of the product is usually more complicated. At the same time, due to the specific matching relationship, the dimensional tolerance of the workpiece is very small. Between), put forward high requirements on the mold. Since the raw material is a flat material and the shape of the final product is a three-dimensional shape, the material will undergo a series of changes such as extension, flow, elastic deformation, and plastic deformation during the forming process. In order to prevent the material from being unstable and wrinkling during the stretching process, At the same time, the shape of the product meets the tolerance requirements. The mold must first be supported by the lower ejector cylinder to complete the forming of the parting...
