Injection mold and demolding mechanism thereof

Abstract

The invention discloses an injection mold. The injection mold comprises an upper mold base, a lower mold base, a top plate fixedly connected to the top of the upper mold base, a bottom plate fixedly connected to the bottom of the lower mold base and a groove formed in the top of the lower mold base, a sleeve is movably connected to the inner part of the groove, a limiting mechanism is movably connected to the inner part of the sleeve; the limiting mechanism comprises a fixing column, a through hole is formed in the inner part of the fixing column, a lifting rod is movably connected in the inner part of the through hole, and through grooves are formed in the positions, located on the periphery of the through hole, of the inner part of the fixing column. According to the injection mold and ademolding mechanism thereof, limiting and fixing sleeves with different diameter specifications are carried out, the sleeves which need the corresponding diameter specifications are arranged on the fixing column in a sleeving mode, the fact that plastic circular rings with different hole diameters can be machined on the injection mold in an injection molding mode can be realized, and molds with other sizes do not need to be additionally used, so that the application range of the injection mold is widened, and meanwhile certain economic cost is reduced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold and a demoulding mechanism thereof. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products. In short, molds are tools used to make shaped objects , This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object through the change of the physical state of the formed material, known as the "mother of industry". [0003] Referring to the injection mold with the Chinese Patent Publication No. CN210161531U, this patent document can facilitate the up and down operation of the first piston plate by using the jacking column, and by setting a plurality of first mold columns, and surrounding the centra...

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides an injection mold and its demoulding mechanism, which solves the problem that the injection molding work of different aperture sizes of plastic rings cannot be realized on a single mold, which leads to poor application range of the mold and the existing The demoulding method is easy to cause damage to the surface of the product to a certain extent, making it difficult for the quality of the product after injection molding to meet the actual processing needs
