Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile parts, and specifically relates to a cavity sound insulation rubber block double -color injection molding slider direction lock glue structure. BACKGROUND

[0002] The EVA foamed glue of the cavity sound insulation rubber block horizontally downward (or in the opposite direction of the main body EVA) will sag during the baking process without the lock glue structure, finally affecting the performance, the product formed by the traditional secondary injection molding process can increase the lock glue column under the premise of keeping the product profile unchanged, and improve the performance of the cavity sound insulation rubber block, but the degree of automation is low, and the production efficiency is low.

[0003] At present, the product formed by the double -color injection molding process is high in automation and production efficiency, but the EVA foamed glue part horizontally downward (or in the opposite direction of the main body EVA) cannot be formed as the same structure by the slider structure, so if the product needs the EVA foamed glue part horizontally downward (or in the opposite direction of the main body EVA), the double -color injection molding process needs to be abandoned, and the secondary injection molding process with low automation degree is selected. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is that the cavity sound insulation rubber block with the EVA foamed glue part horizontally downward (or in the opposite direction of the main body EVA) can only adopt the secondary injection molding process, and the production efficiency is low.

[0005] In order to solve the above problems, the technical scheme of the utility model is as follows: a cavity sound insulation rubber block double -color injection molding slider direction lock glue structure, comprising a framework, the framework is provided with a buckle, and a cavity is formed below the buckle in the interior of the framework, a second EVA foamed glue is arranged in the cavity, a plurality of lock glue columns are fixedly connected to the top of the cavity of the framework, a plurality of positioning holes are formed in the bottom of the cavity, and an EVA column extending into the interior of the positioning hole is fixedly connected to the bottom of the second EVA foamed glue.

[0006] Further, grooves are formed in the top surface of the framework on both sides of the buckle, and the two ends of the cavity are communicated with the two grooves respectively.

[0007] Further, the first EVA foamed glue is arranged in the groove.

[0008] Further, the first EVA foamed glue, the second EVA foamed glue and the EVA column are integrally formed.

[0009] Compared with the prior art, the utility model has the advantages that the EVA foamed glue part of the first EVA foamed glue and the second EVA foamed glue increases the lock glue column and the EVA column, and is formed as the slider structure, so that it can be applied to the double -color injection molding process with high automation degree, thereby guaranteeing the performance of the cavity sound insulation rubber block and improving the production efficiency.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS
