Description

Technical Field

[0001] This utility model relates to the field of casting, and in particular to a casting device for machine tool base casting blanks. Background Technology

[0002] As a core load-bearing component of mechanical equipment, the forming quality of the machine tool base directly determines the overall machine's operational accuracy and service life. Currently, the industry generally adopts gravity casting technology for production, and the specific operation process is as follows: The process implementation stage exhibits significant technical characteristics: the casting system configuration requirements are such that, due to the large size of the machine tool base, the casting mold needs to be equipped with multiple pouring points, and the cavity is filled by synchronously injecting molten metal.

[0003] If a single-point sequential pouring method is used, the molten metal will cool down in the far-end area, causing a decrease in fluidity and leading to forming defects such as under-casting and cold shuts, which seriously affects the yield of finished products. Therefore, in order to ensure synchronous pouring at multiple points, a dedicated operator needs to be assigned to each pouring station to transfer the molten metal by controlling the tilting angle of the storage ladle. This requires a large amount of manual labor, which increases production costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a casting device for machine tool base casting blanks.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A casting device for machine tool base blanks includes: a support bracket, which is composed of an upper support plate and a lower support column welded together; a collection groove for collecting casting liquid is formed at the top of the support bracket; and an injection pipe is welded and fixed to the bottom of the collection groove to facilitate direct entry of the casting liquid into the injection hole of the mold. A diversion groove is formed at the center of the top of the support bracket, and the top side of the diversion groove is flush with the top side of the collection groove. Thus, when the casting liquid is guided into the diversion groove by a guiding mechanism, it is diverted into the collection groove through the diversion groove, and then injected into the injection hole of the mold through the injection pipe.

[0006] Preferably, the bottom of the bracket is fixed with casters by bolts. In order to facilitate the movement and fixation of the casters, the casters are provided with a locking mechanism (not shown in the figure) for fixing the casters.

[0007] Preferably, a guiding mechanism for guiding the flow of the casting liquid is fixedly installed on the top of the bracket.

[0008] Preferably, the guiding mechanism includes a guide plate, and a discharge pipe is welded and fixed to the bottom of the guide plate near the end of the diversion channel, the discharge pipe being located at the top center of the diversion channel. A support frame for supporting the guide plate is welded and fixed to the outside of the discharge pipe, the bottom of the support frame being welded and fixed to the top of the bracket.

[0009] Preferably, the bottom of the guide plate is inclined toward the diversion channel, which facilitates the rapid passage of the casting liquid through the guide plate under the action of gravity and reduces the amount of casting liquid residue on the guide plate.

[0010] Preferably, a heating assembly for heating the guide plate is also installed at the bottom end of the guide plate.

[0011] Preferably, the heating assembly includes a housing welded and fixed to the bottom of the guide plate. An inner housing is welded and fixed to the bottom end of the guide plate, the inner housing being located inside the outer housing, and a vacuum gap exists between the outer side of the inner housing and the inner side of the outer housing for heat preservation. An electric heating element for heating is bolted to the inner side of the inner housing. A conduit is embedded and fixed to the upper part of the inner housing.

[0012] Preferably, the conduit is fixedly inserted through the outer shell and extends to the outside of the outer shell for threading wires, facilitating the connection of the heating element to the power supply.

[0013] Compared with the prior art, the beneficial effects of this utility model include: 1. Under the diversion effect of the guide plate, the pouring liquid flows into the collection tank through the diversion tank, and then into the pouring port through the injection pipe at the bottom of the collection tank. This achieves multi-point synchronous pouring, which can be operated by one group of people, eliminating the need for multiple groups of people to perform multi-point pouring operations, thus greatly saving labor.

[0014] 2. The heating element heats the bottom of the guide plate. When the pouring liquid is directly injected into the guide plate, the temperature difference between the pouring liquid and the guide plate is reduced by heating, thereby reducing the temperature loss of the pouring liquid, ensuring the quality of subsequent pouring, ensuring the fluidity of the pouring liquid, and preventing the pouring liquid from remaining on the guide plate.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0018] A casting device for machine tool base blanks includes: a support bracket 1, which is composed of an upper support plate and a lower support column welded together; a collection groove 4 for collecting the casting liquid is provided at the top of the support bracket 1; and an injection pipe 5 is welded and fixed to the bottom of the collection groove 4 to facilitate the direct entry of the casting liquid into the injection hole of the mold. A diversion groove 3 is provided at the center of the top of the support bracket 1, and the top side of the diversion groove 3 is flush with the top side of the collection groove 4. Thus, when the casting liquid is guided into the diversion groove 3 by a guiding mechanism, it is diverted into the collection groove 4 through the diversion groove 3, and then injected into the injection hole of the mold through the injection pipe 5.

[0019] In this embodiment, the bottom of the bracket 1 is fixed with a caster wheel 6 by bolts. In order to facilitate the movement and fixation of the caster wheel 6, the caster wheel 6 has a locking mechanism for fixing the caster wheel 6 (not shown in the figure).

[0020] In this embodiment, a guiding mechanism for guiding the flow of the casting liquid is fixedly installed on the top of the bracket 1.

[0021] Specifically, the guiding mechanism includes a guide plate 7, the bottom of which is inclined towards the distribution channel 3 to facilitate the rapid passage of the casting liquid through the guide plate 7 under gravity and reduce casting liquid residue on the guide plate 7. A discharge pipe 8 is welded and fixed to the bottom of the guide plate 7 near the distribution channel 3, and the discharge pipe 8 is located at the top center of the distribution channel 3. A support frame 2 for supporting the guide plate 7 is welded and fixed to the outside of the discharge pipe 8, and the bottom of the support frame 2 is welded and fixed to the top of the bracket 1.

[0022] In this embodiment, a heating component for heating the guide plate 7 is also installed at the bottom of the guide plate 7.

[0023] In this embodiment, the heating assembly includes a housing 9 welded and fixed to the bottom of a guide plate 7. An inner housing 10 is welded and fixed to the bottom end of the guide plate 7. The inner housing 10 is located inside the housing 9, and a vacuum gap exists between the outer side of the inner housing 10 and the inner side of the housing 9 for heat preservation. An electric heating element 12 for heating is fixed to the inner side of the inner housing 10 by bolts. A conduit 11 is embedded and fixed on the upper part of the inner housing 10. The conduit 11 extends through the housing 9 to the outer side of the housing 9 for threading wires, facilitating the connection of the electric heating element 12 to a power source.

[0024] Working principle: During use, the bracket 1 is moved to the top of the mold to be poured by the caster 6, and the injection pipe 5 is located directly above the pouring port of the mold. The caster 6 is then locked by the locking mechanism (the locking of the caster 6 is existing technology, so the structure of the locking mechanism will not be described in detail). The pouring liquid is then moved to the side of the guide plate 7 through the storage tank and then poured out, so that the pouring liquid passes through the guide plate 7 and then is discharged into the diversion tank 3 through the discharge pipe 8. Under the diversion effect of the diversion tank 3, the casting liquid flows into the inside of the collection tank 4, and then into the pouring port through the injection pipe 5 at the bottom of the collection tank 4, thus realizing multi-point synchronous casting. Before the pouring work is carried out, the electric heating tube 12 is turned on to heat the bottom of the guide plate 7. When the pouring liquid is directly injected into the guide plate 7, the temperature difference between the pouring liquid and the guide plate 7 is reduced by heating, thereby reducing the amount of temperature loss of the pouring liquid and ensuring the quality of subsequent pouring.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
