Description

Technical Field

[0001] This utility model relates to the field of rubber product manufacturing technology, specifically to a disassembly and assembly mechanism for a rubber pressing mold. Background Technology

[0002] Molds are tools used to make shaped items. When producing rubber products with complex structures or that need to meet the requirements of sealing and compressive strength, such as sealing rings and rubber gaskets, they are often formed by high-temperature extrusion using hot press molds. Among them, O-ring compression molds are composed of an upper template and a lower template, and the upper and lower templates are respectively provided with annular cavities with a semi-circular cross section.

[0003] In existing technologies, the space available for forming O-rings in molds is relatively small, and each forming structure can only press out one O-ring, resulting in a low O-ring yield. To solve the problems existing in the prior art, utility model with publication number CN218139416U discloses a high-capacity O-ring production mold (hereinafter referred to as Prior Art 1), including a first module, in which a mold cavity is recessed on the mold mating surface of the first module, and a first retaining ring is protruding in the mold cavity, the first retaining ring surrounding a sheet cavity for forming the mold piece within the mold cavity, and a plurality of first forming parts protruding within the sheet cavity, each of the first forming parts including a plurality of first annular cavities; a second module, in which a plurality of second forming parts are protruding on the mold mating surface of the second module, each of the second forming parts including a plurality of second annular cavities; wherein, the first annular cavity and the second annular cavity correspond one-to-one, and the corresponding first annular cavity and the corresponding second annular cavity are configured to form an O-ring on the mold piece.

[0004] Although the production rate of O-rings is improved by the cooperation of the first forming part and the second forming part in the prior art 1, the surface temperature of the sealing ring after high temperature extrusion molding is too high, which makes it difficult to remove and affects the subsequent processing efficiency of the sealing ring.
