Embodiment Construction

[0021] Such as figure 2 and image 3 As shown, the structure of the combination mold for long and narrow composite material molding parts is as follows: the lower long and narrow splint I7, the lower long and narrow splint II9 and the lower long and narrow splint III10 are respectively placed above the lower bottom plate 6, and the lower long and narrow splint The cross-section in the width direction of II9 is ​​a trapezoidal structure with a narrow top and a wide bottom. One side of the lower long and narrow splint I7 and one side of the lower long and narrow splint III10 are respectively closely matched with the side of the lower long and narrow splint II9; Place the upper long and narrow splint Ⅰ2, the upper long and narrow splint Ⅱ3 and the upper long and narrow splint Ⅲ4. One side of the long and narrow splint III4 is closely matched with the side of the lower long and narrow splint II9; The combined profiles of the narrow splint I2, the upper long narrow splint II3 an...

Abstract

The invention relates to a processing method of a long-narrow composite material molding part assembling mould. The processing method of the long-narrow composite material molding part assembling mould comprises the following steps of: (1) processing an upper bottom plate and a lower bottom plate; (2) processing a long-narrow clamp plate: (2.1) reserving the margin of 3mm for the thickness and the width; (2.2) carrying out thermal treatment; (2.3) leveling by a bench worker, planning and milling the upper and lower surfaces to be parallel, and reserving a margin of 1mm; and (2.4) numerically processing a matching profile in the width direction and reserving a margin of 1mm; (3) carrying out overall processing on the assembled upper and lower long-narrow clamp plates: (3.1) trimming the involution gaps between three clamp plates respectively; (3.2) grinding two planes in the thickness direction of the overall grinding; and (3.3) numerically processing the upper and lower profiles to meet the dimensional requirement, and then polishing the profiles by bench workers. By using the processing method, the problems that the long-narrow composite material assembling part deforms and the connection of the contact surfaces is poor, the processing precision of the long-narrow assembling mould is improved, and the production efficiency is greatly enhanced.

Description

technical field [0001] The invention relates to a processing method for a combination mold of long and narrow composite material forming parts, which belongs to the field of mechanical processing. Background technique [0002] Such as figure 1 As shown, the long and narrow composite material molded part has an opening and closing angle after the part is formed by the tooling. If the mold is processed as a whole, the part cannot be taken out, so the mold tooling of the part is composed of several long and narrow parts. Since each part is long and narrow, the deformation of a single piece is relatively large, and after a single piece is processed, several parts need to be combined together, so that there will be a gap in the width direction and a gap in the height direction at the joint of the parts. . Because the tooling is used for composite material molding, the composite application has high requirements on the surface quality and precision of the molding mold, so the ga...
