Structure of arc-shaped gasket forming die

Abstract

The arc-shaped gasket forming mold structure comprises a middle mold plate with a conical through hole in the middle, two spliced half blocks are installed in the conical through hole of the middle mold plate, and the half blocks are detachably spliced to form a conical whole to be installed in the conical through hole of the middle mold plate; and the mold core extends into the middle parts of the two half blocks to form a two-section interval space for accommodating the two arc-shaped gaskets. The two arc-shaped gaskets are formed in the interval space between the two half blocks and the mold core, so that the arc-shaped gaskets are separated from the middle mold plate between the half blocks and the mold core, then the half blocks are separated from the radial peripheries of the arc-shaped gaskets, and the situation that the arc-shaped gaskets are pulled out in the axial direction and are cracked and deformed is avoided; the problem that the arc-shaped gasket is cracked and deformed when being axially pulled out is solved.

Description

Technical Field

[0001] The utility model relates to a structure of an arc gasket forming die, belonging to the technical field of dies. Background Art

[0002] When making an arc gasket from rubber material, in the prior art, a core 1 is installed in a middle template 2 to form two arc-shaped spaced spaces, and the rubber material cures in the arc-shaped spaced spaces to form two arc gaskets 3, as Figures 3 to 4 shown. When taking out the arc gasket 3, since the arc gasket 3 is made of rubber material, it will generate an adsorption force with the core 1 and the middle template 2. Directly pulling out the arc gasket 3 axially will cause problems of cracking and deformation. Content of the Utility Model
