Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 and 2, this embodiment provides a casting model for preventing casting gas pocket is produced to V method, including parting plate 1, is equipped with reference column 2 on the parting plate 1, is equipped with model 4 on the parting plate 1, is equipped with on the parting plate 1 and directly waters pole 3 and a plurality of pole 5 of giving vent to anger, directly waters pole 3 and sets up the one side at model 4. Set up the model respectively on the match plate 1, during the drawing die, can avoid appearing the gas pocket in the die joint department, and with the intensity height of the model of match plate 1 even as an organic whole, can effectively improve the life of loose piece, the loose piece that prevents some positions when the model drawing from drops automatically, the qualification rate when improving production has also guaranteed the stability and the uniformity of product, the utility model discloses simple structure, practicality are strong, have very big spreading value.
As shown in fig. 3, the mold comprises an upper mold 4 and a lower mold, and an air outlet rod 5 is arranged on the upper mold 4. The parting plate 1 is arranged between the upper model 4 and the lower model, and the cope flask 8 and the drag flask 7 can simultaneously press the film, so that the film pressing time is reduced.
As shown in fig. 4 and 5, embodiment 2, the utility model provides a prevent casting model of V method production foundry goods gas pocket, including parting plate 1, be equipped with reference column 2 on the parting plate 1, the middle part of parting plate 1 is equipped with the model. Still include cope flask 8 and drag flask 7, parting plate 1 sets up in the parting surface department of cope flask and drag flask 7. The processed model is respectively arranged on the parting plate 1 according to an upper model and a lower model, the parting plate 1 provided with the upper model 4 is provided with a ventilation rod, and one side of the model is provided with a direct pouring rod 3.
