Embodiment Construction
[0014] Now in conjunction with accompanying drawing, the present invention will be further described.
[0015] Such as Figure 1-5 As shown, the foundry casting die device includes a mounting base, a base plate 6, an upper die mechanism, a lower die mechanism, and a vibration mechanism. The mounting seat includes the lower mounting seat 1 and the upper mounting seat 5. The upper die mechanism includes a support 14, a rotating frame 1401, an upper cylinder 15, and a pressing plate 13. The lower die mechanism includes a lower cylinder 3 and a push plate 7. The vibration mechanism includes a motor 2. , transmission belt 4, pulley 10, rotating shaft 9. The specific structure is as follows: an inner cavity is formed inside the upper mounting base 5, and the four raised positioning seats 101 distributed in a rectangular shape in the lower mounting base 1 are positioned by using the inner cavity and the four raised positioning seats 101, and are fixed by fasteners (screws, bolts). ...

The invention relates to a foundry casting die pressing device which comprises a mounting seat, a base plate and an upper die pressing mechanism. The upper die pressing mechanism comprises a support, an upper air cylinder and a pressing plate. The mounting seat comprises a lower mounting seat body and an upper mounting seat body, and a mounting cavity for mounting a vibration mechanism and lower die pressing mechanism therein is formed between the two mounting seat bodies. The vibration mechanism comprises a motor and two or more rotating shafts, the motor is fixed to the lower mounting seat body and in transmission connection with all the rotating shafts through belt wheels and a transmission belt, one end of each rotating shaft is rotatably positioned to the lower mounting seat body, and the other end of each rotating shaft is provided with one-piece tooth discs A with ends provided with tooth-shaped faces. The base plate is located on the upper surface of the upper mounting seat body, the bottom of the base plate is provided with tooth discs B meshed with the tooth-shaped faces of the tooth discs A, and both the tooth discs A and the tooth discs B are movably arranged in through holes formed in the upper mounting seat body; the lower die pressing mechanism comprises a lower air cylinder, and a pushing plate, the lower air cylinder is fixed to the lower mounting seat body and connected with the pushing plate, and the upper mounting seat body is provided with a hole allowing the pushing plate to stretch out. By means of the foundry casting die pressing device, the die pressing pressure can be guaranteed, and die pressing efficiency and efficiency are improved.
Description
technical field [0001] The invention relates to sand foundry casting equipment, which is a sand foundry die casting device. Background technique [0002] The manufacturing process of foundry casting is generally to manufacture the sand mold for casting first, then inject the liquid casting material into the sand mold, take out the casting after cooling, arrange (remove the attached sand, arrange the injection hole) or clean, and the casting is completed. The casting method in the prior art is to place the sand box with the sand mold on the machine table, and then use the air pressure pressing machine to squeeze the sand mold downward. Although this method is simple, it can only be used for For smaller castings, for larger and heavy castings, there is insufficient pressure, and the density of the sand box is not good, so it needs more manual assistance to complete, which is not only time-consuming and laborious, but also has low casting efficiency and is difficult to guarante...
