Generally, the utility model provides an one-way disk seat mould mainly includes mould unit, lower mould unit and waters the unit.

Among them, reference may be made to fig. 1, which shows the arrangement relationship of the upper die unit, the lower die unit, and the runner unit:

the lower die unit is correspondingly arranged below the upper die unit, a pouring gate inlet is arranged on the same side of the upper die unit and the lower die unit, an outlet of the pouring gate unit is connected to the pouring gate inlet, and the pouring gate unit is arranged to be in a structure formed by combining an upper pouring gate 4 and a lower pouring gate 5 for preventing aluminum water from splashing and obtaining a stable flowing liquid state; in addition, for convenience of installation, disassembly, maintenance and no damage to the quality of a product during demolding, for this purpose, the upper runner 4 is installed on the side wall of the upper die unit through bolts, and the lower runner 5 is installed on the side wall of the lower die unit through bolts and is positioned below the upper runner 4; furthermore, an inclined inlet flow channel 6 is formed between the lower runner 5 and the upper runner 4.

It should be specifically noted that the feeding runner 6 can be divided into a top feeding port 601, a transition runner 602 and a bottom feeding port 603 which are integrally arranged from top to bottom, wherein the top feeding port 601 is arranged at one side far away from the upper die assembly and is positioned at the top, and the bottom feeding port 603 is overlapped with an inlet positioned at one side of the top of the lower die 9 to complete the conveying of the molten aluminum; furthermore, in order to match with an inclined feeding runner, in production, the upper pouring gate 4 is set to be of an inverted triangle structure, and the sharp angle of the bottom of the inverted triangle is suitable for 30 degrees; on the other hand, in order to facilitate the aluminum water to enter the feeding runner 6, the width of the top feeding port 601 is larger than the inner diameter of the transition runner 602; furthermore, considering that the aluminum water at the bottom of the feeding runner 6 is accumulated most to prevent vortex or blockage, the bottom feeding port 603 is obliquely arranged with an angle smaller than 2 degrees.

As described above, when molten aluminum enters the casting cavity 3 formed by inwardly recessing the top of the lower mold 9 from the outside, in order to avoid the influence of the internal and external temperature difference on the overall strength, for this reason, at least four sets of upper mold heating pipes 2 and lower mold heating pipes 12 are respectively arranged in the upper mold 1 and the lower mold 9, the area of the casting cavity 3 can be completely covered by the area formed by the plurality of heating pipes 2, and generally, in order to obtain a long service life, the upper mold heating pipes 2 and the lower mold heating pipes 12 are seamless stainless steel pipes.

In use, the following workflow is included:

1. the upper die descends under the action of the equipment, the upper die and the lower die are closed, and molten aluminum enters a casting cavity 3 through a top feeding port 601;

2. the upper die heating pipe 2 and the lower die heating pipe 12 are electrified to ensure that the interior of the die is at a balanced temperature;

3. after the casting is solidified, the equipment drives the upper die 1 to be separated from the lower die 9, and the casting 13 moves upwards along with the upper die 1;

4. after the upper die 1 moves along with the position of the equipment ejection plate 17, the upper die 1 continues to move upwards, the ejection structure is blocked and limited by the equipment ejection plate 17 which is fixed in position, the equipment ejection plate 17 and the ejector rod cover plate 16 drive the ejector rod 14 to eject the casting 13 downwards out of the upper die 1, and the casting 13 is separated from the die;

5. the casting enters the next procedure after being inspected;

6. the equipment drives the upper die to move downwards and the lower die to be combined, the whole casting process is completed, and the next casting is waited.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention.
