A kind of mechanical material preparation mold

Abstract

The invention relates to a mechanical material preparation mold. The mold comprises a seat body, supporting columns are arranged at four corners of the upper surface of the seat body correspondingly,damping devices are arranged inside the supporting columns, and first connecting plates are arranged at the upper ends of the supporting columns; a female mold is arranged on the upper surfaces of thefirst connecting plates, a plurality of evenly-distributed mounting holes I are formed in the female mold, and filling bodies matched with the mounting holes I are arranged in the mounting holes I; and second connecting plates are arranged at the lower ends of the filling bodies, and lifting devices are arranged below the second connecting plates. According to the mold, the female mold is small in thermal expansion coefficient, high in specific strength and light in weight, the surface machining precision is high, the overall structure is reasonable, the stability is good, the machining period of the mold is short, the machining economic cost is low, the stress is uniform during demolding, the operation is convenient, the damage is not easy to occur, labor is saved, working efficiency isimproved, practicability is high, and popularization is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical molds, and in particular relates to a mold prepared from mechanical materials. Background technique [0002] Due to the needs of modern warfare, military electronic equipment is constantly developing in the direction of miniaturization, light weight, and multi-functionality. Reducing costs and improving cost performance have become the pursuit goals of various equipment development and production units. A large-scale millimeter-wave antenna needs to divide the panel into plates during processing, and then manufacture each plate into a mold first, then make the panel on the mold, and then splicing after the completion of the production, but due to the plate division, the divided The number of plates is large, so the processing molds have corresponding requirements.

Problems solved by technology

A large-scale millimeter-wave antenna needs to divide the panel into plates during processing, and then manufacture each plate into a mold first, then make the panel on the mold, and then splicing after the completion of the production, but due to the plate division, the divided The number of plates is large, so the processing molds have corresponding requirements. The conventional method is to use casting to produce the base, and then process the mold surface, but the cost of this processing is very high, and the processing cycle is long, resulting in the processing cycle of the entire antenna. Long, high cost, heavy weight, affected by the resilience of metal processing, its surface accuracy is difficult to control, the highest is only 0.09mm, which makes the dimensional stability of the metal antenna poor during use, and it is very inconvenient to remove the mold , the labor intensity of workers is high and it is easy to affect the surface processing accuracy
