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 method for manufacturing a vacuum port of a composite material mold, comprising the following steps: placing an embedded part on a master mold; The position of the embedded part; the support part is opened, and the connecting end is screwed into the vacuum port base through the fastener. The manufacturing method of a vacuum port of a composite material mold according to the present invention can form a split-type vacuum port, which has low manufacturing cost, simple maintenance in the later stage, partial replacement, and reduced maintenance cost and cycle; precise positioning is realized through embedded parts with protrusions, The base of the metal vacuum port is glued and bonded to the glass fiber reinforced plastic support, so the base of the vacuum port is not easy to be pulled off; if there is a problem with the thread of the through hole of the vacuum port base, only the through hole bushing needs to be replaced, and there is no need to replace the entire base.

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...
