Interface retaining ring limit demoulding structure

Abstract

The invention discloses an interface baffle ring limiting and demoulding structure. The structure comprises a mold core, wherein the mold core is provided with a convex ring, a hollow annular baffle ring and sliding block components; the convex ring is used for forming the opening end of a pipe fitting; the outer wall of the hollow annular baffle ring is fixedly provided with a plurality of guide rail blocks which are uniformly distributed along the radial direction; the sliding block components slides on the guide rail blocks; return springs are arranged between the sliding block components and the baffle ring; the plurality of sliding block components move along the radial direction under the action of the return springs and then are closed to form a through hole which is matched with the diameter of the mold core; and the plurality of sliding block components move along the radial direction and then are opened to form a through hole which is matched with the diameter of the mold core and the height of the convex ring. By the structure, the structure of a pipe fitting mold is simplified, the production efficiency of the pipe fitting mold is improved, the production cost of a product is reduced, and suitable equipment is provided for the automation and the simplification of the pipe fitting mold.

Description

technical field [0001] The invention relates to the field of pipe fitting moulds, in particular to a structure or device for pulling out a ferrule of a pipe fitting mould, Background technique [0002] The pipes used to transport liquids in the construction or chemical industry often require a large number of pipe fittings, and the connection of these pipe fittings also requires a large number of pipe fittings such as tees and crosses; taking tee pipe fittings as an example, the opening of the tee in one direction A protruding ring is provided at the end of the tee, which is used for matching and docking with the connecting pipe fittings, and strengthens the mechanical strength of the opening end; due to the protruding ring, the mold structure of the tee is relatively complicated in the existing mold design, and the volume of the mold It is also relatively large, thus increasing the production cost, which is not conducive to energy saving and environmental protection, so it ...

[0002]Pipes used to transport liquids in the construction or chemical industry often require a large number of pipe fittings, and the connection of these pipe fittings also requires a large number of pipe fittings such as tees and crosses; Taking the tee pipe fitting as an example, a protruding ring is provided at the opening end of the tee in one direction, which is used for matching and docking with the connecting pipe fitting, and strengthens the mechanical strength of the opening end; due to the protruding ring, the tee is When designing existing molds, the structure of the mold is relatively complex, and the volume of the mold is relatively large, which increases the production cost and is not conducive to energy saving and environmental protection. Therefore, it is necessary to improve on this basis
