Abstract
The invention provides a sprue bush structure which can solve the problems in the prior art. The sprue bush structure comprises an upper fixed plate, a positioning ring and a sprue bush, wherein the positioning ring and the sprue bush are sequentially mounted on the upper fixed plate, and the body of the sprue bush comprises an upper sprue opening. The sprue bush structure is characterized in that the upper fixed plate is in interference-fit connection with the positioning ring and the sprue bush respectively.
Description
Technical field
The present invention relates to the technical field of die casting, be specially a kind of sprue bush structure.
Background technology
In the design of die casting system, usually the design sprue bush shortens the length of runner, existing sprue bush structure as shown in Figure 1, sprue bush 4 is made split type, comprise standard component centring ring 2 and sprue bush 3, centring ring 2 and sprue bush 3 are installed on the upper mounted plate 1 by screw 8, screw 7 orders respectively, and this split type sprue bush structure has dwindled the volume of whole sprue bush.But because overall structure is little, the setting of a plurality of screws, so that complexity is installed, and the limited space of screw is set, the outer rim of screw is got close in outer wall, and is not painstaking in causing installing, easy damaged lid.
Summary of the invention
For the problems referred to above, the invention provides a kind of sprue bush structure, can solve the problem that prior art exists.
Its technical scheme is such, it comprises upper mounted plate, centring ring and sprue bush sequentially are installed on upper mounted plate, and the body of described sprue bush comprises running-on, it is characterized in that: the fixed plate respectively with described centring ring, described sprue bush between interference fit be connected.
It is further characterized in that: be provided with cannelure, lower cannelure at the fixed plate, and described lower cannelure and the same center of circle of described upper cannelure, and be positioned at the inner ring of described upper cannelure;
The bottom of the body of described centring ring is provided with round platform, and described round platform is installed in described upper cannelure, and with described upper cannelure interference fit;
The bottom of the body of described upper running-on is provided with round platform, and described round platform is installed in described lower cannelure, and with described lower cannelure interference fit.
In the said structure of the present invention, upper mounted plate adopts interference fit respectively and between the centring ring, sprue bush, has saved too much screw setting, and is easy for installation simple, solved the problem of prior art.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention.
The specific embodiment
See Fig. 2, the present invention includes upper mounted plate 1, upper mounted plate 1 is provided with cannelure 1-1, lower cannelure 1-2, lower cannelure 1-2 and the same center of circle of upper cannelure 1-1, and be positioned at the inner ring of cannelure 1-1; Split type sprue bush 4 comprises centring ring 2 and sprue bush 3, centring ring 2 and sprue bush 3 orders are installed on the upper mounted plate 1, the bottom of the body of centring ring 2 is provided with round platform 2-1, and the body of sprue bush 3 comprises running-on 3-1, and the bottom of the body of upper running-on 3-1 is provided with round platform 3-2; Round platform 2-1 is installed in cannelure 1-1, and with upper cannelure 1-1 interference fit, round platform 3-2 is installed in lower cannelure 1-2, and with lower cannelure 1-2 interference fit, 5 is mouth of a river stripper plate among the figure.
During installation, first sprue bush 3 is buckled in the installation opening 6 between upper mounted plate 1 and the mouth of a river stripper plate 5, be interference fit therebetween, the bottom round platform 3-2 of the upper running-on 3-1 of sprue bush 3 bodies is installed on lower cannelure 1-2, be interference fit therebetween, the bottom round platform 2-1 with the body of centring ring 2 is installed on upper cannelure 1-1 again, is interference fit therebetween, so just finish the installation of whole split type sprue bush 4, convenient and simple.
