Utility model content
The purpose of this utility model is to provide a kind of core be shaped for tubular injection moulding piece endoporus, and this core can not only ensure tubular injection moulding piece endoporus two axiality, and manufactures easy, with low cost.
The technical scheme realizing the utility model object is: the utility model comprises mold core body and slide block assembly; Described mold core body comprises the first core and the second core, and the outer circumference surface of the first core and the second core is provided with shaping periphery; Described slide block assembly comprises the first slide block and the second slide block that are oppositely arranged, and the first slide block is fixedly connected with one end of the first core, and the second slide block is fixedly connected with one end of the second core; After the free end of described first core and the free end of the second core dock, the first core and the second core form mold core body; The free end of described first core is provided with the groove coaxial with the shaping periphery of the first core; The free end face of described second core is provided with the boss coaxial with the shaping periphery of the second core; Described boss and groove corresponding matching and the first core and the second core butting rear boss embed in groove completely.
Above-mentioned first core is connected with the first slide block and the second slide block by pin respectively with the second core; Described first slide block and the second slide block are fixed with respectively the briquetting for compressing the first core and the second core; Described briquetting is provided with the suit hole walked for the first core or the second core; The one end in described suit hole is provided with the coupling part be connected with the first slide block or the second slide block, and the aperture of the other end is provided with the annular edge-pressing strip extended radially inwardly; Described first core and the link of the first slide block are provided with the annular lug coordinated with the edge-pressing strip of briquetting; Described second core and the link of the second slide block are provided with the annular lug coordinated with the edge-pressing strip of briquetting.
Above-mentioned groove and boss are cylindrical.
Above-mentioned groove and boss are circular cone shape; The small end face of described boss is free end.
The utility model has positive effect: (1) the utility model is coordinated by coaxial groove and boss, realizes the axiality of the first core and the second core, thus ensure that the axiality at tubular injection moulding piece endoporus two; (2) mold core body is assembled on slide block assembly by briquetting and pin by the utility model, installs simple and convenient, decreases manufacturing cost; (3) boss of the present utility model and groove adopt circular cone shape, can reduce the friction of projection and groove, increase the service life of mold core body.
