Embodiment
The present invention is described in further details below in conjunction with the accompanying drawings：
Principle：After molten metal is full of casting die cavity, seals piston A and seal piston B synchronous interaction, can either close
Casting die cavity, it can make to fill the molten metal backflow in type passage again.
Using：The present apparatus can be used for after filling type, to being sealed at casting die cavity cast gate.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of improved hub extrusion casting mould closing device of the utility model,
Including sealing oil cylinder 2 and piston cylinder 9, the sealing piston A4 being arranged in piston cylinder 9 and sealing piston B7, piston cylinder 9 is arranged on
The cast gate 5 that casting cavity bottom is connected with the neighbouring upper ends of sealing piston A4 on top, be arranged on the top of piston cylinder 9 with sealing
Intercommunicating pore 6 neighbouring piston B7, the lower end between cast gate 5 and intercommunicating pore 6 of the bottom of piston cylinder 9 is arranged in molten metal
Stalk 10；Also include connecting rod A3 and connecting rod B8, connecting rod A3 one end is rigidly connected with sealing piston A4, the other end and flange A11
It is rigidly connected, connecting rod B8 one end is rigidly connected with sealing piston B7, and the other end is rigidly connected with flange B12, flange A11 flanges
B12 shape adaptations simultaneously connect, and sealing oil cylinder 2 in the middle part of connecting rod A3 with being rigidly connected so as to seal works of the piston A4 in sealing oil cylinder 2
With lower movement, sealing piston B7 is also rigidly connected with sealing oil cylinder 2 by connecting rod B8 and connecting rod A3 and sealed so as to seal piston B7
Moved in the presence of mouth oil cylinder 2；Pressure chamber 14 wraps up stalk 10, intercommunicating pore 6, and pressure chamber 14 has also wrapped up the lower half of cast gate 5
With a part for piston cylinder 9, intercommunicating pore 6 and the air communication in pressure chamber 14, the left end of piston cylinder 9 pass through the wall and pressure of pressure chamber 14
The outside connection of room 14, the right-hand member of piston cylinder 9 connect also through the wall of pressure chamber 14 with the outside of pressure chamber 14；Such as Fig. 1 and Fig. 2 institutes
Show, during device original state, seal the unclosed cast gates 5 of piston A4, sealing piston B7 closed communications hole 6, as shown in Figure 3 and Figure 4,
After molten metal is full of die cavity, sealing piston A4 closing cast gates 5, the unclosed intercommunicating pores 6 of piston B7 are sealed.
In the utility model device, because sealing piston A4 can be extruded after sealing by molten metal, therefore to sealing piston A
Material require higher, as preferred embodiment of the present utility model, consider from heat-resisting, pressure-resistant and high-abrasive material manufacture envelope
Mouth piston A, such as the steel that the trade mark is 2Cr25Ni20.
As preferred embodiment of the present utility model, the sealing oil cylinder 2 and piston cylinder 9 are each attached on workbench 1.
As preferred embodiment of the present utility model, the flange A11 and flange B12 is rigidly connected by bolt 13.
Operation principle of the present utility model is divided into following four step：
Step 1：Matched moulds.Before filling type, initial positions of the sealing piston A (4) in left end.Ensure cast gate (5) and stalk
(10) passage between is unimpeded, as shown in Figure 1.
Step 2：To the air pressurized in pressure chamber (14), the molten metal in crucible passes through stalk under pressure
(10) and cast gate (5), into casting die cavity.
Step 3：After molten metal is full of die cavity, sealing piston A (4) is moved from left to right in the presence of sealing oil cylinder (2)
It is dynamic.At the same time, it is rigidly connected due to sealing piston B (7) by connecting rod B (8) and connecting rod A (3) and sealing oil cylinder (2)；Therefore seal
Mouthful piston B (7) is synchronous with sealing piston A (4) holding also in the presence of sealing oil cylinder (2), moves from left to right.Work as sealing
When piston B (7) left side is moved to intercommunicating pore (6) inner left wall, air and molten metal contacts in pressure chamber (14), such as Fig. 3
It is shown.And now, the molten metal in casting die cavity is sealed piston A (4) and is enclosed in casting mold.Therefore, in stalk (10)
Molten metal is back in the crucible for containing molten metal under gravity.
Step 4：To casting pressurize, treat that casting solidification finishes.Die sinking, and eject casting.Finally, oil cylinder (2) is sealed to drive
Sealing piston A (4) and sealing piston B (7) is moved to the initial position in left side.
