Abstract
The utility model provides a positioning structure of a sprue bushing of an injection mold. The positioning structure ensures that the sprue bushing does not rotate during operation of the mold and then ensures that air imputes are not mixed, so that the flow velocity is uniform, and the quality of products subjected to injection molding is guaranteed. The positioning structure comprises the sprue bushing, an upper press cover, a panel and a flow channel, wherein the sprue bushing is arranged inside an installation cavity of the panel, the lower end of the sprue bushing is communicated with the flow channel, the upper press cover covers the upper end surface of the sprue bushing, and the upper press cover is fixedly connected with the panel. The positioning structure is characterized in that a limiting groove is formed in the upper part of one side of the sprue bushing, a positioning groove is formed in the upper end surface of the installation cavity of the panel, the limiting groove and the positioning groove form a linear groove structure, and a positioning column is embedded in the linear groove structure formed by the limiting groove and 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 of injection mould.
Background technology
The sprue bush of existing injection mould 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 of injection mould, 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 of injection mould, 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 sidepiece top of described sprue bush has stopper slot, the upper surface of the installation cavity of described panel has locating slot, described stopper slot, locating slot forms straight-line groove structure, locating dowel is flush-mounted in described stopper slot, in the straight-line groove structure that locating slot forms.
Adopt after structure of the present utility model, above sidepiece due to sprue bush, have stopper slot, the upper surface of the installation cavity of panel has locating slot, and stopper slot, locating slot form straight-line groove structure, in locating dowel is flush-mounted in the straight-line groove structure that stopper slot, locating slot form, it makes the circumferential fixing of sprue bush, it guarantees mould in the course of the work, and 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.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
