Abstract
The utility model provides a positioning structure of a sprue bushing. The positioning structure of the sprue bushing guarantees that the sprue bushing cannot rotate during the working process of a mold and then guarantees that air impurities cannot be mixed, so that the flow velocity is uniform, and the product quality after injection moulding is ensured. The positioning structure comprises the sprue bushing, an upper gland, a panel and a flow passage, wherein the sprue bushing is placed in a mounting cavity of the panel; the lower end of the sprue bushing is communicated with the flow passage; and the upper gland is mounted on the upper end surface of the sprue bushing in a covering manner and is fastened and connected with the panel. The positioning structure is characterized in that a bulged positioning screw is fastened at the side part of the sprue bushing, a positioning groove is formed in the upper end surface of the mounting cavity of the panel, and the bulged part of the positioning screw is arranged in the positioning groove.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of location structure of sprue bush.
Background technology
Existing sprue bush is all cylinder or circular cone structure, it is in mold work process, easily rotate, make runner loosening, entrained air impurity or flow velocity are inhomogeneous, thereby make the of poor quality of product after injection mo(u)lding, and because sprue bush is generally placed in mould inside, sprue bush rotates generally cannot be realized.
Summary of the invention
The utility model provides a kind of location structure of sprue bush, and it guarantees mould in the course of the work, and sprue bush can not rotate, and then guarantee not can entrained air impurity, makes flow velocity even, guarantees the product quality after injection mo(u)lding.
A kind of location structure of sprue bush, its technical scheme is such: it comprises sprue bush, top gland, panel, runner, described sprue bush is placed in the installation cavity of described panel, the lower end of described sprue bush is communicated with described runner, described top gland mounts cover the upper surface in described sprue bush, described top gland is fastenedly connected described panel, it is characterized in that: the fastening dog screw that protrusion is housed of sidepiece of described sprue bush, the upper surface of the installation cavity of described panel has locating slot, and the projection of described dog screw is placed in described locating slot.
Adopt after structure of the present utility model, the fastening dog screw that protrusion is housed of sidepiece due to sprue bush, the upper surface of the installation cavity of panel has locating slot, the projection of dog screw is placed in locating slot, and it makes the circumferential fixing of sprue bush, and it guarantees that mould in the course of the work, sprue bush can not rotate, and then guarantee not can entrained air impurity, make flow velocity even, guarantee the product quality after injection mo(u)lding.
