Embodiment Construction

[0021] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0022] Such as Figures 1 to 4 As shown, a method for manufacturing a vacuum port of a composite material mold in this embodiment includes the following steps: S100: placing the embedded part 1 on the master mold 2; S200: after the support part 3 of the composite material mold is prepared, remove the Embedded part 1, put the vacuum port base 4 into the original embedded part position; S300: open the support part 3, and screw the connecting end 5 into the vacuum port base through the fastener 6. In the above technical solution, one end 51 of the connecting end 5 is located in the base of the vacuum port, and the other end 52 communicates with the vacuum system. When communicating with the vacuum system, it can be connected by a quick connector or by a clamp or the like. Thus, th...

Abstract

The invention relates to a manufacturing method for a vacuum port of a composite material mould. The manufacturing method comprises the following steps: placing a pre-embedded part onto a female mould; removing the pre-embedded part after a supporting part of the composite material mould is manufactured, and putting a vacuum port base into the original pre-embedded part position; and breaking through the supporting part, and enabling a connecting end head to pass through a fastening part to screw into the vacuum port base. The manufacturing method for the vacuum port of the composite materialmould can form a split type vacuum port, is low in manufacturing cost, is simple in later-stage maintenance, can be locally replaced, reduces maintenance cost and shortens a maintenance period; precise positioning is realized through the pre-embedded part with a bulge, and the metal vacuum port base is adhered with glue and is bonded with a glass fibre reinforced plastic supporting part, so that the vacuum port base is not easily dropped by pulling; and if threads of a through hole of the vacuum port base have problems, only a through hole lining needs to replace, and the whole base does not need to replace.

Description

technical field [0001] The invention relates to the technical field of composite material molds, in particular to a method for manufacturing a vacuum port of a composite material mold. Background technique [0002] With the gradual development of composite material molding technology, many shapes are complex, and even require later assembly. It is difficult for composite material parts prepared by using traditional material molds to meet the tolerance requirements, but composite material molds can. Composite molds need to install a vacuum port to connect to the vacuum system for power. Metal molds can be welded to achieve the purpose, but composite material molds can only be pre-embedded for one-time molding or secondary bonding. Therefore, it is difficult to process the vacuum port, and the stability and quality of the vacuum port need to be improved. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a manu...
