Rotary opening type precision die structure capable of achieving fixed-point disassembly and maintenance

Abstract

The invention relates to the technical field of precision dies, and discloses a rotary opening type precision die structure capable of achieving fixed-point disassembly and maintenance. The rotary opening type precision die structure comprises a base and a lower die, the lower die is fixed to the surface of the base, and three middle dies and an upper die are sequentially arranged on the lower die. A clamping structure and supporting structures are arranged between the lower die, the middle dies and the upper die, and the clamping structure comprises a first bolt, a second bolt, inserting holes, a first screw groove, a second screw groove, first screw heads and springs. Transverse grooves are transversely formed in the lower portions of the left sides of the upper die and the middle dies,vertical grooves are formed in the lower sides of the transverse grooves, and under the action that abutting bolts cooperate with oblique blocks, supporting rods and universal ball wheels which are arranged inside the vertical grooves can be controlled to move downwards in the vertical grooves to abut against the surfaces of the middle dies or the lower die where the universal ball wheels abut against on the lower side. After the upper die or the middle dies are supported, the rotation is labor-saving, and the abrasion is reduced.

Description

technical field [0001] The invention relates to the technical field of precision molds, in particular to a rotating and open precision mold structure capable of fixed-point disassembly and maintenance. Background technique [0002] At present, molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, molds are used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] When repairing precision molds, it is generally to remove all the bolts on the precision molds, and then remove the spliced ​​mold plates one by one, and then repair the inner cavity of the precision mold. This maintenance method It is more complicated...

Problems solved by technology

[0003] When repairing precision molds, it is generally to remove all the bolts on the precision molds, and then remove the spliced ​​mold plates one by one, and then repair the inner cavity of the precision mold. This maintenance method It is more complicated, and some molds can be rotated and opened at the specified position. However, due to the gravity of the mold when opening, the pressure between adjacent molds is relatively high, it is not easy to rotate and open, and the friction is easy to damage the mold when opening.
