[0053] The air intake assembly 33 is connected to the sand storage 32. By providing the air intake assembly 33, the sand shooting operation can be performed in a manner of airflow suspension sand shooting, so that the sand mold has a certain pre-tightening force and forms a good sand mold structure;

[0054] The material level meter is arranged inside the sand storage 32, and the sand height inside the sand storage 32 can be detected by the material level meter. When the requirement is reached, the sand feeding component 31 is controlled to stop feeding sand, and then the subsequent sand shooting operation can be carried out.

[0055] As an optional embodiment, the sand inlet assembly 31 includes a sand inlet hopper 311, a sand inlet gate valve 312 and a sand inlet gate valve cylinder 313, the sand inlet gate valve 312 is connected between the sand inlet hopper 311 and the sand reservoir 32, and the sand inlet gate valve cylinder 313 is transmission-connected to the sand inlet gate valve 312;

After the sand inlet gate valve 312 is opened, the external sand supply device can be connected to the sand storage 32;

[0057] When the molding machine is in operation, it is necessary to first control the sand inlet gate valve 312 to open through the sand inlet gate valve cylinder 313, so that the external sand supply device is connected to the sand storage 32, and the sand transported by the external sand supply device enters the sand storage 32 after passing through the sand inlet hopper 311.

The multiple air inlets and the switch valves cooperate together to form an airflow suspended sand shooting operation state, so that the sand shooting effect is better.

[0060] In addition, the upper air passage can be used not only for boiling sand shooting, but also for removing the residual air inside the sand storage 32 after the sand shooting is completed.

[0061] As an optional embodiment, the position adjustment mechanism 5 includes a double-rod oil cylinder, which includes a guide cylinder body 51 and a piston rod 52 movably connected to the guide cylinder body 51. The guide cylinder bodies 51 on several double-rod oil cylinders are connected to the upper frame 1 and are symmetrically located on both sides of the sand shooting mechanism 3. All piston rods 52 are connected to the auxiliary sand box 6 after passing through the upper frame 1. The double-rod oil cylinder can drive the auxiliary sand box 6 to move relative to the upper frame 1.

[0062] The guide cylinder body 51 can guide and position the piston rod 52, reduce the deviation of the piston rod 52, and the double-rod oil cylinder can integrate the oil cylinder structure and the guide structure into one, which plays a guiding role while driving the auxiliary sand box 6 to move. It has a simple structure, stable performance, is not affected by the environment and external forces, and has a long service life.

[0063] Moreover, the arrangement of the plug cavity with a rod in the oil cylinder also reduces the area of ​​the plug cavity. When a large force is not required, the flow rate of the oil cylinder also becomes smaller, and the speed of the oil cylinder is increased when the motor and the pump remain unchanged.

[0064] The auxiliary sand box 6 can be driven by the double-rod cylinder to descend to a set initial height at the beginning of each cycle. At the same time, the relative position of the auxiliary sand box 6 can be adjusted according to different product requirements to achieve adjustable sand volume.

[0065] As an optional embodiment, the transmission mechanism 9 includes a support frame 91, a support rail 92 and an auxiliary wheel 93. The two support rails 92 are connected to the top of the support frame 91 and are arranged in parallel. A number of auxiliary wheels 93 are evenly spaced and symmetrically connected on the two support rails 92. The upper sand box 7 and the lower sand box 8 are placed on the several auxiliary wheels 93. The auxiliary wheels 93 can allow the upper sand box 7 and the lower sand box 8 to move. The upper sand box 7 and the lower sand box 8 arranged alternately in sequence can move along the length direction of the support rail 92 under the push of external force. When they move to the bottom of the compaction support frame 4 and the auxiliary sand box 6, the sand shooting operation of the corresponding sand mold can be started.

[0066] As an optional embodiment, the mold seat rotating mechanism 10 includes a rotating shaft 101, a rotating table 102 and a rotating cylinder 103. The top of the rotating shaft 101 is connected to the upper frame 1, and the bottom of the rotating shaft 101 is movably connected to the rotating table 102.

The rotating cylinder 103 is connected to the lower frame 2 and is connected to the bottom of the rotating table 102. After the rotating cylinder 103 is started, it can drive the rotating table 102 to rotate relative to the rotating cylinder 103. During the rotation process, the upper mold seat 20 and the lower mold seat 30 can be alternately replaced, so as to correspond to the upper sand box 7 or the lower sand box 8 respectively.

[0067] As an optional embodiment, the compaction mechanism 40 includes a lower compaction support plate 401, a compaction cylinder 402 and a guide rod 403. The compaction cylinder 402 is connected to the lower frame 2, the lower compaction support plate 401 is connected to the top of the compaction cylinder 402 and forms a guiding connection with a plurality of guide rods 403. The compaction cylinder 402 can drive the lower compaction support plate 401 to move in the vertical direction.

[0068] As an optional embodiment, it further includes a guide light axis 50, the upper frame 1 is connected to the top of all the guide light axes 50, and the lower frame 2 is connected to the bottom of all the guide light axes 50;

[0069] The guide optical axis 50 can play a fixing role on the upper frame 1 and the lower frame 2;

[0070] In addition, the two guide light axes 50 preferably pass through the lower compaction support plate 401 , and when the lower compaction support plate 401 moves, the guide light axes 50 can play a role in guiding and positioning.

[0071] As an optional embodiment, it also includes a locking box mechanism 60, which is connected to the lower frame 2. When the lower compaction support plate 401 rises to contact the upper mold seat 20 or the lower mold seat 30, the locking box mechanism 60 can lock the lower compaction support plate 401 and the upper mold seat 20 or the lower mold seat 30. This arrangement is mainly to ensure that when the lower compaction support plate 401 descends, the lower compaction support plate 401 and the upper mold seat 20 or the lower mold seat 30 can move synchronously. When the upper mold seat 20 or the lower mold seat 30 descends to the set extreme position, that is, returns to the placement position of the rotating table 102, the locking box mechanism 60 can release the lock.

[0072] As an optional embodiment, it also includes a multi-contact oil cylinder mechanism 70, which is arranged inside the compaction support frame 4. The multi-contact oil cylinder mechanism 70 preferably includes a plurality of oil cylinder monomers 701. During the compaction operation of the molding machine, the bottoms of all the oil cylinder monomers 701 can contact the sand mold, so that the oil cylinder monomers 701 can cooperate with the compaction mechanism 40 to further improve the compaction operation effect.

[0073] Furthermore, all the cylinder units 701 can be concentrated on one oil circuit or on several different oil circuits, so that all the cylinder units 701 are integrated together for centralized control. When concentrated on one oil circuit, unified control can be achieved, and when concentrated on several different oil circuits, multi-channel control can be achieved. Under the drive of an external hydraulic station, the extension and retraction actions of all the cylinder units 701 can be controlled.

[0074] The working principle of the fully automatic static pressure molding machine is as follows: in the initial state, the auxiliary sand box 6 is driven by the double-rod oil cylinder of the position adjustment mechanism 5 to descend and move to the calculated initial position for sand injection molding;

[0075] According to whether the flask moved to the bottom of the compaction support frame 4 and the auxiliary flask 6 is the upper flask 7 or the lower flask 8, the rotating cylinder 103 of the mold seat rotating mechanism 10 is started, driving the rotating table 102 to rotate, thereby driving the upper mold seat 20 or the lower mold seat 30 to move to the bottom of the upper flask 7 or the lower flask 8;

[0076] Taking the lower sand box 8 and the lower mold seat 30 as an example, the compacting cylinder 402 of the compacting mechanism 40 is started, driving the lower compacting support plate 401 to move upward. During the movement, it first contacts the lower mold seat 30, and drives the lower mold seat 30 to separate from the rotating table 102, so that the lower mold seat 30 moves upward synchronously, and then the top of the lower mold seat 30 contacts the bottom of the lower sand box 8, so that the lower sand box 8 also moves upward synchronously, until the upper surface of the lower sand box 8 moves to be flush with the lower surface of the auxiliary sand box 6, and the compacting cylinder 402 temporarily stops working;

[0077] Then the sand shooting mechanism 3 is started, and the sand delivered by the external sand supply device can be delivered to the sand storage 32 through the sand feeding component 31, and then the sand in the sand storage 32 is blown into the lower sand box 8 and the auxiliary sand box 6 through the air intake component 33 to fill the two.

[0078] Then the compaction cylinder 402 continues to lift upward to perform compaction operation, or the compaction cylinder 402 cooperates with the multi-contact cylinder mechanism 70 to perform compaction operation together. During the compaction operation, the double-rod cylinder of the position adjustment mechanism 5 releases the pressure, so that the auxiliary sand box 6 can gradually move upward during the compaction process;

[0079] After the compaction operation is completed, the auxiliary sand box 6 moves to the top limit position, and the compaction oil cylinder 402 starts to move downward. At the same time, the lower sand box 8 and the lower mold seat 30 move downward synchronously. During the movement, the lower sand box 8 returns to the transmission mechanism 9, and the lower mold seat 30 returns to the rotating table 102, completing the single operation of the lower sand box 8;

[0080] Since the lower sand box 8 and the upper sand box 7 are placed alternately on the transmission mechanism 9, after completing a single operation of a lower sand box 8, the next one that needs a single operation is the upper sand box 7, so the above steps can be repeated to perform a single operation on the upper sand box 7. In this process, it is necessary to drive an upper sand box 7 to move to the bottom of the compaction support frame 4 and the auxiliary sand box 6 through the transmission mechanism 9, and the rotating cylinder 103 of the mold seat rotating mechanism 10 is started to drive the rotating table 102 to rotate, thereby driving the upper mold seat 20 to move to the bottom of the upper sand box 7, and then the above steps can be repeated;

[0081] Repeat the above steps to alternately operate the lower flask 8 and the upper flask 7 on the transmission mechanism 9, thereby realizing automated assembly line production.

[0082] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
