Problems solved by technology

For the flexible manufacturing of small-sized three-dimensional curved surface parts, because of its small size, it is impossible to set one axis input and one axis output for each basic unit body. At the same time, due to the size of the basic unit body, the total number of mold units is limited. The flexible mold The basic unit body is relatively sparse, and the flexible mold cannot realize the forming of complex curved surfaces

Abstract

Provided are small dense multi-point flexible molds. One set of small dense multi-point flexible mold is connected with a slide block of a pressure machine, and the other set of small dense multi-point flexible mold is connected with a base of the pressure machine. The small dense multi-point flexible molds finish shape adjustment through a shape adjusting device. Each small dense multi-point flexible mold comprises a bottom board, an upper pressing board and a mold board which are connected through four first guide columns, wherein multiple unit body layers are arranged between the bottom board and the upper pressing board; a partition board is arranged between every two unit body layers; each unit body layer is provided with a plurality of basic unit bodies; the intervals among the basicunit bodies are the same; springs are installed on the first guide columns between the bottom board and the partition boards, between the two partition boards as well as between the partition boardsand the upper pressing board; and the upper pressing board is connected with an output shaft of a hydraulic cylinder fixed to the mold board. The small dense multi-point flexible molds can achieve anysmall-size three-dimensional flexible injection molding through the flexible injection molding molds, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of flexible manufacturing, in particular to a small dense multi-point flexible mold. Background technique [0002] Flexible manufacturing is the development trend of the processing industry, among which "dieless multi-point forming technology" is an advanced manufacturing technology that integrates flexible forming technology and computer technology, and is a three-dimensional surface digital forming technology for sheet metal. For the flexible manufacturing of small-sized three-dimensional curved surface parts, because of its small size, it is impossible to set one axis input and one axis output for each basic unit body. At the same time, due to the size of the basic unit body, the total number of mold units is limited. The flexible mold The basic unit body is relatively sparse, and the flexible mold cannot realize the forming of complex curved surfaces. The traditional multi-point mold considers the arran...
