Problems solved by technology

For structures that require a continuous sealant, this open injection method is no problem, however, for the case where a sealant with a special shape or structure is required to be formed in a localized area of ​​the groove , it becomes very difficult, for example, when it is necessary to form a sealant with a notch of a predetermined shape, it is very difficult
Because, in open glue injection, the liquid sealant injected into the groove is unconstrained, it will flow freely in the groove, and its shaping is very difficult, so it cannot form a seal with a predetermined shape of the groove glue
In order to obtain a sealant with a predetermined shape of the notch, after the open glue injection, it is necessary to perform cutting, grinding and other processes to remove the spilled or excess sealant, so it is very time-consuming and wastes a lot of sealing Glue, resulting in increased costs

Abstract

A method of injecting a sealing gel into a recess (8) of a work piece to form a predetermined structure defined by sealing gel at a local region (9) of the recess, comprising steps of: providing a molding tool (2) having an insertion structure complementary to the predetermined structure; enclosing the local region of the recess with the molding tool, and injecting a fluid sealing gel into the molding tool; and after the sealing gel has been cooled and solidified, dismantling the molding tool so that the predetermined structure defined by sealing gel is formed at the local region of the recess.

Description

technical field [0001] The invention relates to a method for injecting sealant in a groove, in particular to a method capable of forming a sealant with a predetermined structure in a local area of ​​the groove. Background technique [0002] At present, the method of injecting the sealant into the groove is generally: directly injecting the liquid sealant into the opening of the groove. For structures that require a continuous sealant, this open injection method is no problem, however, for the case where a sealant with a special shape or structure is required to be formed in a localized area of ​​the groove , it becomes very difficult, for example, when it is necessary to form a sealant having a notch of a predetermined shape, it is very difficult. Because, in open glue injection, the liquid sealant injected into the groove is unconstrained, it will flow freely in the groove, and its shaping is very difficult, so it cannot form a seal with a predetermined shape of the groove...
