Description

Technical Field

[0001] The present application relates to the technical field of waste recovery devices, and in particular to a waste recovery device for the production and processing of casting molds. Background Art

[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity, and after the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.

[0003] The structure of the casting mold is complex, so a large amount of waste is usually generated during the production and processing of the casting mold. A recovery device is needed to collect and process the waste of the casting mold to ensure the recovery speed of the casting mold waste. For example, the Chinese patent with publication number CN220836616U in the related technology proposes a solid waste management and recovery device, which has the advantage of making the sieve plate slide in the groove on the inner wall of the screening tank by moving the tooth nails at the outer end of the gear to contact the convex nails at the bottom end of the sieve plate, so that the sieve plate vibrates repeatedly to discharge the stone particles that meet the aperture from the sieve hole of the sieve plate. The apertures of the three groups of sieve plates are different, so that three different particle sizes of particles can be screened out, and each layer of the sieve plate can collect stones of different particle sizes, thereby improving the stone screening efficiency.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: when recycling casting mold waste, it is necessary to first crush the casting mold waste, but the waste recovery device of this design has the disadvantage of poor crushing effect, resulting in the mold waste having different volumes during the recycling and collection process, which is not convenient for subsequent processing of the mold waste. Furthermore, the staff are required to screen and clean the mold waste, which not only increases the labor intensity of the staff, but also affects the effect of the recycling device on the recycling of mold waste. It is inconvenient to use, cannot meet the actual use needs, and reduces the use efficiency and effect of the recycling device. Utility Model Content

[0005] In order to solve the problem that the existing waste recovery device for casting mold production and processing has a shortcoming of poor crushing effect, which causes the mold waste to have different sizes during the recycling and collection process, making it inconvenient to process the mold waste in the subsequent process, and further requires staff to screen and clean the mold waste, affecting the recycling effect of the recovery device on the mold waste, the present application provides a waste recovery device for casting mold production and processing.

[0051] The implementation principle of a waste recovery device for casting mold production and processing in the embodiment of the present application is as follows:

[0052] By opening the movable cover, the mold waste that needs to be recycled can be poured into the inner side of the recycling box 1. The mold waste can be dropped between the two crushing rollers 8 by the limitation of the two limiting plates 21. The movable shaft 4, the first gear 5 and the driving wheel 9 can be driven to rotate in sequence by the motor 3. Because the first gear 5 is meshed with the second gear 6, the second gear 6 and the connecting shaft 7 will be driven to rotate in sequence during the rotation of the first gear 5. During the rotation of the movable shaft 4 and the connecting shaft 7, the two crushing rollers 8 will be driven to rotate relative to each other. When the two crushing rollers 8 rotate relative to each other, the mold waste can be crushed, and the crushed mold waste will fall to the bottom of the crushing chamber, thereby achieving the purpose of crushing the mold waste.

[0053] Because the driving wheel 9 and the driven wheel 11 are both connected to the transmission belt 10, the driving wheel 9 rotates, which in turn drives the transmission belt 10, the driven wheel 11, the driving shaft 12 and the first bevel gear 13 to rotate. Because the first bevel gear 13 is meshed with the second bevel gear 14, the first bevel gear 13 rotates, which in turn drives the second bevel gear 14, the supporting shaft 15 and the sixteen crushing blades 16 to rotate. Therefore, when the crushed mold waste falls downward, the mold waste can be crushed for the second time through the rotation of the sixteen crushing blades 16, which can enhance the effect of the mold waste crushing and can crush the mold waste into small pieces.

[0054] After the mold waste is crushed, the discharging frame 20 can be opened by the electromagnetic valve 24, so that the crushed mold waste inside the crushing chamber can be placed into the inner side of the collecting box 19 through the discharging frame 20 for collection. The movable pressing block 18 can be driven by the electric push rod 17 to move up and down. During the up and down movement of the movable pressing block 18, the mold waste inside the collecting box 19 can be flattened, thereby increasing the quantity and effect of the collecting box 19 on the mold waste collection. The collecting box 19 can be limited by the fixed square groove to avoid shaking or deviation of the collecting box 19 during the process of collecting the mold waste, thereby ensuring the effect of the collecting box 19 on the mold waste collection.

[0055] Compared with the prior art, the overall structure is simple and easy to use, and the purpose of good mold waste crushing effect is achieved, and the volume of mold waste is avoided to be different during the recycling and collection process, so as to facilitate the subsequent processing of the mold waste. There is no need for staff to screen and clean the mold waste, which reduces the labor intensity of the staff, improves the effect of the recycling device on the recycling and processing of mold waste, meets the actual use needs, and improves the use efficiency and effect of the recycling device.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
