Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sand casting, more particularly, to a sand casting post-molding shakeout device. BACKGROUND

[0002] When processing alloy or casting, the solidified alloy needs to be taken out of the sand mold with the help of a shakeout device, and the sand attached to its surface needs to be removed. The device can effectively separate the casting from the sand through a specific working mechanism, providing convenient conditions for subsequent cleaning and processing procedures. During the shakeout process, the separated sand needs to be systematically collected and processed again. After such processing, the sand can be reused in the subsequent alloy and casting processing steps, thereby reducing production costs and improving resource utilization.

[0003] Chinese patent document (CN115194131B) discloses a sand casting shakeout device, which proposes in the specification that "it includes a feed inlet, the lower surface of the feed inlet is fixedly connected with an outer cover, the lower surface of the outer cover is fixedly connected with a base, and the inner part of the outer cover is rotatably connected with a crusher. The present application relates to the technical field of sand casting. When the device is in use, the raw materials fall from the gap on both sides of the top block. When the device stops using, the adjusting rod is pushed down. Since the bottom block is fixed, the lower surface of the side plate contacts the upper surface of the bottom block. The bottom of the controller is closed. Then rotate the screw. Under the action of thread connection, the top block slides down along the inner surface of the feed inlet until its lower surface contacts and fits the outer surface of the side plate. The top of the controller is closed. Through multi-stage sealing, the sealing performance of the device is improved while reducing noise propagation, preventing dust from scattering, and solving the problem of poor protection effect of traditional shakeout devices when crushing raw materials", but it still has the problem of poor screening effect in actual use. When crushing large sand blocks, the internal structure may be damaged, thereby affecting the service life of the processing device.

[0004] Traditional sand casting equipment lacks an effective sand crushing and screening step before the shakeout step, which leads to untreated sand being directly filled into the casting, and large particle sand raw materials mixed therein often block the internal structure of the casting, thereby causing internal jamming and damage of the equipment. Such problems not only seriously hinder the smooth progress of the subsequent shakeout process, but also greatly shorten the service life of the equipment and pose a safety hazard during use. In view of this, we propose a sand casting post-molding shakeout device. SUMMARY

[0005] The present application aims to provide a sand casting forming post-molding shakeout processing device to solve the technical problem of lack of crushing and screening before shakeout in traditional sand casting equipment, which causes large particle sand to easily block the casting parts, resulting in equipment jamming and damage, affecting the service life and safety.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. This invention, through the design of a two-stage crushing component and a compression component, allows raw materials to enter the processing tank through the inlet and be directly isolated inside the tank, sealing the inlet. A motor drives the drive shaft, and the sand and gravel impact the baffles along with the primary crushing blades, falling into the secondary crushing component. Medium-sized sand and gravel are ground by the secondary crushing component before falling, while small sand and gravel fall directly. Large sand and gravel are subjected to pressure within the secondary crushing component. This allows the device to accelerate the discharge of sand and gravel through a combination of gas pushing and gravity, and can quickly process sand and gravel of different volumes, avoiding resource waste caused by repeatedly processing small and medium-sized sand and gravel. This ensures the safety and processing quality of the device. Furthermore, by processing the fallen sand multiple times, it reduces the risk of uneven sand volume clogging inside alloy castings during subsequent secondary use, thus ensuring the processing quality of the alloy castings.

[0021] 2. This invention also incorporates a compression component. During drive shaft operation, medium and large sand and gravel are located within the crushing shell. The crushed blocks continuously rub against the medium and large sand and gravel as the drive shaft moves. Large sand and gravel struggle to enter the space between the crushed blocks and the crushing shell, resulting in low crushing efficiency. As the drive shaft continues to move, the compression block contacts the guide baffle and is pressed downwards. This compresses the large sand and gravel, increasing friction between them and the crushing shell, thus crushing the large sand and gravel. When the compression block detaches from the guide baffle, it quickly resets under the force of a first spring. This process repeats, preventing the compression block from affecting the downward movement of the sand and gravel, allowing the sand and gravel to stably enter the space between the crushing shells. Furthermore, after entering the crushing shell, the sand and gravel undergo secondary crushing. For large sand and gravel, the device can perform tertiary processing, ensuring both efficiency and quality in sand and gravel processing. Multiple processing steps ensure the uniformity of the collected sand volume, preventing blockage within the casting during subsequent casting processing and guaranteeing casting quality.

[0022] 3. This invention also incorporates a pressure component. When the blower is running, it draws air from the isolation cylinder and the processing tank, creating a vacuum between them. The drawn gas is then continuously injected into the sealing sleeve, increasing the pressure inside and pushing the slide rod outward. This causes a large amount of gas to be discharged and discharged downward along the isolation cylinder, reducing the time the processed sand and gravel remain in the device. This ensures the efficiency of the device in processing sand and gravel and prevents sand and gravel residue from affecting subsequent processing, thus ensuring the service life of the device.
