The molten metal is cooled and formed in the casting cavity to obtain a workpiece of a predetermined shape and size.

[0003] At present, in the process of producing pouring cups, it is usually necessary to produce a pouring cup blank, and then dry and sinter the pouring cup blank to obtain the pouring cup; and the pouring cup blank is usually formed by a traditional press or by casting using a casting mold. For the pouring cup blank formed by a traditional press, due to long-term use of steel molds, severe wear and tear, and the introduction of impurities on the mold and other equipment reasons, the quality of the pouring cup blank is seriously reduced; in addition, the cost of producing the pouring cup blank using traditional press pressing equipment is relatively high.

The molding body 1, core 3, lower blocking block 2 and upper blocking block 4 are all subjected to hydraulic pressure to produce elastic deformation toward the pouring cup molding cavity, and the high-temperature resistant dry powder in the pouring cup molding cavity is squeezed from the circumferential direction and the up and down directions respectively, thereby improving the uniformity and sufficiency of the extrusion of the high-temperature resistant dry powder in the pouring cup molding cavity, which is beneficial to improving the quality of the extruded pouring cup blank.

[0087] An embodiment of the present application, such as Figures 2 to 4 As shown, the pouring cup molding device also includes:

[0088] The centering positioning structure is installed in the cavity and is used to limit the vertical center line of the core 3 placed in the cavity to coincide with the vertical center line of the cavity in the vertical direction.

[0089] In this embodiment, if Figures 2 to 4 As shown, in this embodiment, the vertical center line of the core 3 placed in the cavity is limited to coincide with the vertical center line of the cavity by the centering positioning structure in the vertical direction, which is conducive to quickly placing the core 3 in the center of the cavity, so that at the same height position in the vertical direction, the distance between the outer wall of the core 3 and the inner wall of the cavity is consistent, so that the thickness of the high-temperature resistant dry powder filled at the same height position of the pouring cup molding cavity is the same, which is convenient for the subsequent extruded pouring cup blank to have the same thickness at the same height position, thereby improving the quality of the extruded pouring cup blank.

[0090] In this embodiment, if Figures 2 to 4As shown, the centering and positioning structure in this embodiment includes a centering and positioning ring 5. An annular mounting groove is provided between the cavity and the upper opening in this embodiment. The centering and positioning ring 5 is installed in the annular mounting groove.

For example, the centering positioning structure is set on the upper side of the lower blocking block 2, and a limiting groove 1 for limiting the core 3 is set on the upper side of the lower blocking block 2, and the vertical center of the limiting groove 1 coincides with the vertical center line of the cavity, and the core 3 is placed in the limiting groove 1, so that the vertical center of the core 3 coincides with the vertical center line of the cavity. Similarly, the centering positioning structure can also be set on the lower side of the upper blocking block 4, and a limiting groove 2 for limiting the core 3 is set on the lower side of the upper blocking block 4, the vertical center of the limiting groove 2 coincides with the vertical center line of the cavity, and the core 3 is placed in the limiting groove 2, so that the vertical center of the core 3 coincides with the vertical center line of the cavity. It should be noted that when the core 3 is limited by setting the limiting groove 2 on the upper blocking block 4 so that the vertical center of the core 3 coincides with the vertical center line of the cavity, it is necessary to install the upper blocking block 4 first, and fill the high-temperature resistant dry powder into the pouring cup molding cavity from the lower opening, and install the lower blocking block 2 after the high-temperature resistant dry powder is filled.

[0092] Furthermore, in the absence of a centering positioning structure, the vertical center line of the core 3 placed in the cavity can be manually or in other ways to ensure that it coincides with the vertical center line of the cavity in the vertical direction.
