Interface retainer ring limiting stripping structure as above, is characterized in that: described way block and be 4 with the slide block assembly quantity that way block is equipped with, in quartering circle distribution.
Interface retainer ring limiting stripping structure as above, is characterized in that: be provided with a storage tank in the middle part of described way block, has the head of a slide rail block to be placed in storage tank; Described core is provided with projection with corresponding section, slide rail block position.
Interface retainer ring limiting stripping structure as above, it is characterized in that: described projection longitudinal section is isosceles trapezoid, described slide rail block is sequentially provided with the first inclined-plane coordinated with the first central plane of projection longitudinal section, the first plane coordinated with the upper bottom surface of projection longitudinal section, described first plane length equals the horizontal range of bulge loop to projection, the second inclined-plane coordinated with the second central plane of projection longitudinal section, the second plane coordinated with the upper bottom surface of projection longitudinal section, described second plane length is more than or equal to the upper bottom surface length of projection longitudinal section, the 3rd inclined-plane be arranged in parallel with the first inclined-plane, the 3rd plane on the same face is positioned at the first plane.
Interface retainer ring limiting stripping structure as above, is characterized in that: described slide block assembly is provided with spring eye.
When inserting core, first central plane of projection longitudinal section and the first contact of incline plane changing of the relative positions of way block, stir slide block assembly gradually until the upper bottom surface of projection longitudinal section and way block first plane are placed on same plane, the through hole of back-up ring is opened to maximum gradually and is convenient to pass through bulge loop, core continues to put in, the translation of projection upper bottom surface is until the second central plane of projection longitudinal section and the second contact of incline plane changing of the relative positions of way block, described slide block assembly produces closed action under action of reset spring, until projection upper bottom surface is attached in guide rail pole second plane move to predetermined station; After injection moulding completes, when extracting core out, between projection and slide rail block, inverse said process moves and the initial position that resets to when inserting core; When producing pipe fitting, move in circles according to this.
This invention simplifies the structure of pipe fitting mold, improve the production efficiency of pipe fitting mold, reduce production cost, be a kind ofly suitable for equipment for the automation of pipe fitting mold and simplification provide.
