专利说明:
The invention relates to the processing of thermoplastic polymeric materials and can be used to make tubular articles with undercuts from them, for example fittings and pipe fittings having at least one annular groove. A known mold for the manufacture of thermoplastic materials of tubular products with half-rim, containing the outer half-mold with a movable part, installed inside the outer platform with the possibility of axial movement of the forming core with placed on it with the possibility of reciprocating axial movement of the sleeve with the annular edge, to form an undercut 1, An annular rib of known shape includes ring sectors interacting with a wedge mechanism, which complicates the design of the mold, reduces the reliability of its operation, and does not eliminate the flow of material between the ring sectors, and this reduces the quality of the products. . The closest to the technical essence and the achieved effect to the proposed is a casting mold for the manufacture of thermoplastic materials for tubular products with undercuts, containing an outer split half-mold with an installed side with a reciprocating axial movement of the core and concentrically placed on it a sleeve for decorating the site the inner surface of the product, made with an annular protrusion, and a sleeve for decorating a section of the outer surface of the product, the latter being etc. from outside wife ioy split mold half on the side of the end surfaces .i However, the known arrangement | br for1 quite complicated, since it .in provided for sequentially moving the sleeves clearance portions inside and outside surfaces of articles, which have for yu sustained fit exactly these sleeves. In addition, elements are necessary to ensure that the sequence of displacement of the sleeves, The purpose of the invention is to simplify the form design. This goal is achieved by the fact that in the mold for the manufacture of thermoplastic materials tubular products with an undercut containing the outer split half with installed in it with the possibility of reciprocating axial movement of the core and concentrically dispersed) a sleeve for shaping a portion of the inner surface of the product, made with an annular protrusion, and a sleeve for shaping a portion of the outer surface of the product, the latter mating with the outer detachable half-form along the side and end surfaces, a sleeve for shaping the inner surface of the product and a sleeve for shaping the outer portion product surfaces are rigidly connected to each other and to the core. In addition, the sleeve for shaping the outer surface of the product is made with an inclined end surface, and the outer detachable half-form is made with a corresponding resistant surface. Such a constructive solution allows, by using the elastic deformation of the thermoplastic material, to reduce the number of interacting design elements and eliminate the need for their sequential movement, with the possible formation of undercuts in the products to a depth equal to about 10% of the internal diameter of the product. Along with this, making the sleeves mated with the end surface for shaping a portion of the outer surface of the product and the corresponding thrust surface of the outer split half-form oblique reduces, due to the wedge effect, compressing the servo-drive force and preventing the formation of overburden. FIG. 1 shows the upper part of the mold, a longitudinal section j in FIG. 2 — the mold at one of the points of its opening j in FIG. 3, the section of the product. The casting mold for the manufacture of thermoplastic materials for tubular products with undercuts contains an outer split half mold 1 with a core 2 installed on it with the possibility of reciprocating axial movement and having a sleeve 3 concentrically biased on it 1 to design a portion of the inner surface of the product made with an annular a protrusion 4 for molding an undercut 5 on the product, and a sleeve 6 for shaping the outer surface of the product, the sleeves being rigidly connected to each other and with the core 2. The sleeve 6 for shaping the outer surface of the product is mated with the outer half-form along the side 7 and end 8 surfaces, the end surface 8 being inclined and the outer detachable half-form 1 with the corresponding stop surface 9.
