A core pulling formwork

Abstract

The invention provides a core-pulling mold frame, belongs to the technical field of molds, and solves the problem that the core-pulling effect is non-ideal due to long-time use of a conventional core-pulling mold frame. The core-pulling mold frame comprises a base and a connecting base which is arranged on the upper side of the base and can perform reciprocated lifting movement relative to the base, wherein a mounting part which can be used for mounting a lower mold is arranged on the upper side of the connecting base; a core-pulling mechanism is arranged at the side part of the mounting part and comprises a first slide block movably connected onto the connecting base; a linkage mechanism hinged with the connecting base is further arranged between the connecting base and the first slide block; and the linkage mechanism can drive the first slide block to perform horizontal reciprocated movement relative to the mounting part when the connecting base performs lifting movement. According to the core-pulling mold frame, the core pulling of the mold can be performed smoothly, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a mold base, in particular to a core-pulling mold base. Background technique [0002] At present, the known cold stamping is a processing method that uses the die installed on the press to apply pressure to the material to cause separation or plastic deformation to obtain the required parts. The forming process is the plasticity of the material without cracking. Deformation, so as to obtain parts with certain shape, size and precision requirements, such as bending, deep drawing, bulging, flanging, cutting, fine blanking, etc. Although they have different characteristics, hemming is to roll the edge of the process part into a close closed The circular shape is used to process similar parts. Blanking is to separate the closed contour of the material, and the separated part is mostly flat-shaped parts into process parts, while punching is to separate the waste from the material or proc...

Problems solved by technology

However, because the stamping mold uses the inclined wedge to squeeze the inclined surface of the slider to make the slider move back and forth horizontally to achieve the purpose of core pulling, after a long time of use, the inclined surface between the inclined wedge and the slider is easy to wear, so the core pulling effect not ideal
