Embodiment Construction
[0050] The casting mold has a simple structure, and the specific structure has been introduced before, and the specific implementation will be described in conjunction with the operation process below.
[0051] The operating process of the present invention comprises the following steps:
[0052] a. Preparatory work, including molten metal, preheating casting molds, coating, assembling casting molds, etc.;
[0053] b. Hook the fixed lifting ring (3) with a sling, slowly immerse the casting mold in the molten metal (8), the lower pressure plug (9) will leave the gate (6) due to its own weight, and the molten metal (8) will The lower feeding cavity (5), the mold cavity (12), the upper feeding cavity (13) and part of the opening (2) are filled sequentially through the gate (6) until the fixed lifting ring (3) rests on the molten pool ( 11) On the edge or on the special shelf, complete the pouring work, remove the spreader, such as figure 1 with figure 2 shown;
