Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a rubber sealing ring mold which is easy to demould. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Among them, injection molds are required in the molding process of rubber sealing rings.

[0003] There is a close relationship with all kinds of molds, which are used in our daily production and life. The various tools and products, which are as large as the base of the machine tool and the body shell, are as small as the first embryo screws, buttons, as well as the shell of various household appliances.

[0004] For example, the prior art Chinese patent publication number "CN219726922U" provides a rubber sealing ring mold that is easy to demold, including a square plate and a cover plate, the square plate is provided with a circular groove, a round block is installed on the cover plate, an annular plastic sheet is placed in the circular groove, the round block is covered with an annular plastic film, and a cooling device is installed on the square plate.

[0005] The device lays an annular plastic sheet on the bottom of the circular groove in advance, and covers the annular plastic film on the round block. After the rubber sealing ring is formed, when the cover plate is removed, the inner ring of the formed rubber sealing ring contacts the annular plastic film, and the bottom contacts the annular plastic sheet, so that the formed rubber sealing ring is easy to demould from the mold; the water pump sucks water out of the water tank and fills the annular water pool through the water inlet pipe, so that the raw materials in the rubber sealing ring mold between the round block and the circular groove are cooled and quickly formed. After cooling is completed, the valve is opened, and the water in the annular water pool flows back to the water tank through the reflux pipe, which is convenient for secondary utilization.

[0006] The existing rubber sealing ring mold which is easy to demould is easy to stick to the inside of the mold after the rubber sealing ring is injected. The stuck rubber sealing ring cannot be pushed to separate from the mold, which makes it inconvenient to take out the rubber sealing ring. Moreover, when injecting rubber sealing rings of different diameters, different molds need to be replaced, which is quite troublesome.
