Abstract
The utility model relates to production equipment of a heavy-caliber plastic connecting flange. The production equipment comprises a housing, a mold core and an upper cover, wherein the upper cover is arranged on the housing, an injection hole for feeding is formed at the center of the upper cover, the mold core is arranged on the bottom surface inside the housing, a guide groove corresponding to the injection hole is formed in the upper surface of the mold cover, and a cooling water cavity is formed inside the housing. The production equipment is characterized in that a plurality of ring-shaped bosses are arranged on the inner surface of the upper cover, and the inner surface of the upper cover between the two adjacent bosses is of a concave arc shape. The production equipment of the heavy-caliber plastic connecting flange has the advantages of ensuring the flatness of the upper surface of a connecting ring of the connecting flange and improving the tightness of the upper surface of the connecting ring.
Description
Technical field
The utility model relates to a kind of process units of adpting flange, relates in particular to a kind of process units of large-bore plastics adpting flange.
Background technology
At present, the heavy caliber adpting flange comprises connecting ring and tube connector, the large-bore plastics adpting flange is generally manufactured by injection molding way, the process units of large-bore plastics adpting flange comprises housing, core rod and loam cake, loam cake is arranged on the housing, is provided with a hand-hole that is used for charging in the middle of the loam cake, and core rod is connected on the enclosure interior bottom surface, be provided with a guiding gutter in the upper surface of the core rod position corresponding, in housing, be provided with cooling water cavity with hand-hole.Because the inner surface of loam cake is smooth plane, relative aperture owing to adpting flange is bigger when cooling off after the injection mo(u)lding of heavy caliber adpting flange in the process units of large-bore plastics adpting flange, depression can appear in the connecting ring upper surface, have a strong impact on the quality of production of adpting flange, and greatly reduced the sealing property of connecting ring upper surface.
Summary of the invention
At above shortcoming, the purpose of this utility model is to provide a kind of can guarantee that the connecting ring upper surface is smooth, the process units of the large-bore plastics adpting flange of raising connecting ring upper surface sealing property.
Technology contents of the present utility model is: a kind of process units of large-bore plastics adpting flange, it comprises housing, core rod and loam cake, loam cake is arranged on the housing, be provided with a hand-hole that is used for charging in the middle of the loam cake, core rod is arranged on the enclosure interior bottom surface, be provided with a guiding gutter in the upper surface of the core rod position corresponding, in housing, be provided with a cooling water cavity with hand-hole; The inner surface that it is characterized in that loam cake is provided with some annular boss, and the inner surface of the loam cake between adjacent two annular boss is an arcs of recesses.
The advantage that the utility model is compared with prior art had is: because the inner surface of loam cake has increased the material injection rate inwardly for arcs of recesses, make that adpting flange connecting ring upper surface when cooling forming is smooth; Again because the existence of a plurality of annular boss makes the connecting ring upper surface be provided with some annular grooves, sealing ring is placed on behind the connecting ring upper surface when being connected with other pipe fitting, can improve the sealing property of adpting flange.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
