DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] The present application providesFigures 1-4 As shown, an immersion-type sprue forming mold includes a mold connecting body 1 and a mold connecting cover 2 disposed at the upper end of the mold connecting body 1; an upper side connecting ring post 3 is disposed at the middle position of the upper end of the mold connecting cover 2, a connecting rotating threaded post 4 is disposed at the middle position of the upper side connecting ring post 3, a connecting groove 10 is disposed on the side position of the connecting rotating threaded post 4, a compression fastening slope post 9 is disposed on the inner side position of the upper side connecting ring post 3, and an internal connecting contact spring 8 is disposed on the side position of the compression fastening slope post 9, the compression fastening slope post 9 being elastically connected to the upper side connecting ring post 3 through the internal connecting contact spring 8. A pressing contact arc surface block 11 is provided at the bottom of the connecting rotating threaded column 4. The pressing contact arc surface block 11 is connected to the connecting rotating threaded column 4 through a rotating shaft. When the connecting rotating threaded column 4 rotates, it will press the pressing contact arc surface block 11. At the same time, when the pressing contact arc surface block 11 rotates, it will alternately press the pressing buckling slope column 9 inward and press it into the connecting groove 10. When the pressing buckling slope column 9 is pressed into the connecting groove 10, it will knock due to the action of the built-in connecting contact spring 8. Through pressing and slight knocking, the product can be slowly separated from the mold. Its operation is simple and safe, thereby effectively improving the practicality of the immersion sprue forming mold.

[0025] like Figure 4 As shown, the connecting groove 10 is formed by drilling holes on the connecting rotating threaded column 4. The connecting grooves 10 on both sides are staggered at the horizontal position of the connecting rotating threaded column 4. The staggered arrangement of the connecting grooves 10 will not have a significant impact on the thread, and at the same time, it can make the knocking vibration continuous.

[0026] like Figure 1 As shown, the upper part of the connecting rotating threaded column 4 is a non-threaded structure. A threaded groove is provided on the side of the upper part of the connecting rotating threaded column 4. A rotating handle 5 is provided on the side of the connecting rotating threaded column 4 near the upper side. A threaded column is provided on the side of the rotating handle 5. The rotating handle 5 is installed and connected to the connecting rotating threaded column 4 by rotating the threaded column. The rotating handle 5 provides a grip position for the user to easily perform the rotation operation.

[0027] like Figure 2 As shown, the bottom center of the inner side of the mold connecting to the cover 2 is an arc-shaped structure, and a threaded structure is provided at the inner side of the mold connecting to the cover 2. The arc-shaped structure, relative to the flat structure, allows the arc head of the product to be formed directly, which reduces the subsequent grinding process, reduces dust generation, and saves labor and consumables.

[0028] like Figure 3As shown, the upper side of the mold connecting upper cover body 2 is provided with an upper connecting threaded column 6 at the upper part of the mold connecting body 1, the mold connecting upper cover body 2 is installed and connected with the mold connecting body 1 through the upper connecting threaded column 6, and the inner part of the mold connecting body 1 is provided with an inner built-in molding finished product 7, which is a product structure after molding. The mold connecting upper cover body 2 is connected with the mold connecting body 1 through the threaded structure, and the operation is simple and fast, and the sealing property is relatively good.

[0029] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
