Description

Technical Field

[0001] The utility model relates to the technical field of rubber injection molds, in particular to a rubber injection thin-type glue-injection multi-cavity mold. Background Art

[0002] When the rubber injection molding mold is in use, the rubber will be processed into a solution state, and then the liquid rubber will be injected along the injection port of the rubber injection molding mold through an injection machine. After that, it will be cooled and molded along the cavity of the rubber injection molding mold to obtain a rubber product of an ideal shape.

[0003] In today's rubber injection molding molds, it is often found that the mold body is adhered to the product itself during use, which makes it difficult to demold later. In order to solve this problem, a release agent is usually applied between the upper mold and the lower mold to facilitate the separation of the mold and the product later. Therefore, a rubber injection thin-type glue-injection multi-cavity mold is proposed.

[0004] A rubber tube injection mold disclosed in announcement number CN220661562U, although, the rubber tube injection mold includes: a base, a top plate, a lower mold, an upper mold and a bottom plate, the top of the base is provided with a top plate, the lower mold is fixedly installed equidistantly on the surface of the base, the bottom of the top plate is fixedly installed equidistantly on the bottom end of the top plate, the bottom end of the bottom plate is located at the top of the lower mold and the upper mold is slidably installed. Compared with the traditional rubber tube injection mold, the equipment can quickly replace and repair the upper mold that needs to be replaced and repaired regularly during use, making the installation and disassembly of the components themselves simpler, and no additional tools are needed for assistance, reducing the work pressure of the staff themselves, improving the overall work efficiency, and ensuring the stability of the connection between the upper mold and the lower mold, which is convenient for the subsequent material to be plasticized inside the lower mold and the upper mold, making the work quality of the equipment itself more perfect and improving the overall work quality.

[0005] Although the above patent can quickly replace and repair the upper mold that needs to be replaced and repaired regularly, making the installation and disassembly of the components themselves simpler and no longer requiring the use of additional tools for assistance, reducing the work pressure of the staff themselves and improving the overall work efficiency, it can ensure the stability of the connection between the upper mold and the lower mold, making it easier for subsequent materials to be plasticized inside the lower mold and the upper mold, making the work quality of the equipment itself more perfect and improving the overall work quality; however, the device lacks a quick demolding function and requires staff to manually demold, affecting work efficiency.

[0006] Therefore, it is necessary to invent a rubber injection thin-type multi-cavity mold to solve the above problems. Utility Model Content
