Example (b):
the utility model provides a sealed effectual reel casting system, as shown in fig. 1 and 2, includes open case 4, reel model 1, waters model 2, vacuum suction pipe 6, molding sand 3, plastic film 5 and pouring basin 7, plastic film 5 downside be equipped with support ring 8, support ring 8 one side be equipped with the taper sleeve 9 of being connected with plastic film 5, pouring basin 7 one end pass taper sleeve 9.
As shown in fig. 4, the tapered sleeve 9 is provided with four gaps 10, and the four gaps 10 are uniformly distributed on the tapered sleeve 9. This configuration enables the cone-shaped sleeves 9 to be brought together at one end and to cooperate with the cone-shaped configuration of the upper portion of the pouring cup 7.
As shown in fig. 2 and 3, the tapered sleeve 9 is provided with a locking sleeve 11, the locking sleeve 11 comprises a balance part and a locking part for tightening the tapered sleeve 9, and the balance part is matched with the support ring 8 for use, so that impact on the pouring cup 7 during molten metal pouring can be resisted, and the use stability is ensured.
