DETAILED DESCRIPTION

[0026] As Figures 1 to 7 Indicated, the utility model relates to a kind of metal casting sand mould casting device, including microvibration compaction molding machine 1, sand frame 2 is placed on the vibration platform of microvibration compaction molding machine 1, the top of the vibration platform of microvibration compaction molding machine 1 is symmetrically arranged with support control structure 3, and two groups of support control structure 3 are arranged with combined clamping cover 4 between, combined clamping cover 4;

[0027] When sand frame 2 is placed to the vibration platform of microvibration compaction molding machine 1 and carries out sand mould casting, it can be driven combined clamping cover 4 to descend by support control structure 3, make it clamping in sand frame 2 top, realize the butt joint with sand frame 2, then under the cooperation of combined clamping cover 4, the addition amount of red sand can be greatly increased, so when microvibration compaction molding machine 1 is vibrated and compacted to red sand, red sand is always higher than sand frame 2, then red sand higher than sand frame 2 is scraped and removed, thus, without repeatedly adding sand into sand frame 2 and vibrating and compacting, the casting of sand mould can be completed at one time.

[0028] Specifically, the support control structure 3 comprises a support frame 5 and a driving structure 6, the support frame 5 comprises two groups of mounting plates 501, two groups of equidistant mounting rods 502 are arranged between the two groups of mounting plates 501, the mounting plate 501 and the mounting rod 502 are combined to form a rectangular frame structure, a limiting block 503 is arranged on the mounting rod 502 in a sliding mode, the limiting block 503 is connected with the combined clamping cover 4; the driving structure 6 comprises a motor 601, the motor 601 is arranged on the mounting plate 501 at the bottom of the support frame 5, a lead screw 602 is arranged on the output end of the motor 601 through a rotating shaft, and the top end of the lead screw 602 is rotatably connected with the mounting plate 501 at the top of the support frame 5; a driving block 603 is arranged on the lead screw 602, and the driving block 603 is connected with the combined clamping cover 4; the mounting plate 501 and the mounting rod 502 are combined to form a rectangular frame structure fixed on the vibration platform of the micro-vibration compaction molding machine 1, then the limiting block 503 cooperates with the mounting rod 502 to realize the up-down movable installation of the combined clamping cover 4, the motor 601 drives the lead screw 602 to rotate, then the driving block 603 on the lead screw 602 drives the combined clamping cover 4 to move up and down, so that the combined clamping cover 4 is connected with the sand frame 2 and separated from the sand frame 2.

[0029] Further, a rectangular slot 401 is arranged at the bottom of the combined clamping cover 4, the length and width of the inner cavity of the combined clamping cover 4 are same as the length and width of the inner cavity of the sand frame 2, the length and width of the rectangular slot 401 are same as the length and width of the sand frame 2, the combined clamping cover 4 can be inserted into the sand frame 2 through the rectangular slot 401, so that the combined clamping cover 4 is stably connected with the sand frame 2.

[0030] In the embodiment of the utility model, the combined clamping cover 4 is movably arranged with a separation structure 7; a rectangular socket 402 is formed at the back side of the combined clamping cover 4, mounting sleeves 405 are arranged at the two sides of the combined clamping cover 4, the separation structure 7 comprises a mounting frame 701, the mounting frame 701 penetrates through the mounting sleeve 405, a separation plate 702 is arranged at the inside back side of the mounting frame 701, the separation plate 702 is inserted into the rectangular socket 402, limiting grooves 403 are arranged at the two sides of the inside of the combined clamping cover 4, and a shovel groove 706 is arranged at one side of the rectangular socket 402;

[0031] The displacement of the separation plate 702 can be driven by pulling the mounting frame 701. When the mounting frame 701 is pulled forward, the separation plate 702 moves into the combined cover 4 at this time, and the separation plate 702 will move stably along the limiting groove 403. When the mounting frame 701 moves backward, the separation plate 702 is separated from the inside of the combined cover 4, so that the mounting frame 701 and the separation plate 702 can realize the closing and opening effect of the bottom of the combined cover 4. Therefore, after sand casting is completed, the separation plate 702 can be directly moved into the combined cover 4, and at this time the shovel groove 706 tightly abuts the top of the sand frame 2 to separate the red sand that protrudes from the sand frame 2, so that the excess red sand can be better removed, thereby further improving the convenience of one-time sand casting of the combined cover 4.

[0032] When the separation plate 702 moves into the combined cover 4, the mounting strip 703 and the conical block 704 cooperate to crush the red sand scraped off above the sand frame 2, so that it is in a loose state, facilitating subsequent use and further improving the use performance of the combined cover 4.

[0033] Specifically, one side of the shovel groove 706 is an inclined surface, both ends of one side of the shovel groove 706 are inclined surfaces, and the inclined surface of one side of the shovel groove 706 can ensure that the separation plate 702 tightly abuts the top of the sand frame 2 to scrape off the excess red sand. The inclined surfaces at both ends of the shovel groove 706 can push the red sand in the limiting groove 403 to the outside, so that the separation plate 702 cannot move when it moves into the combined cover 4 due to the influence of the red sand in the limiting groove 403.

[0034] Working principle: the embodiment provides a metal casting sand casting device. First, when the sand frame 2 is placed on the vibration platform of the micro-vibration compaction molding machine 1 for sand casting, the combined cover 4 can be lowered by the support control structure 3 to be clamped on the top of the sand frame 2, and the interface with the sand frame 2 is realized. Then, under the cooperation of the combined cover 4, the addition amount of red sand can be greatly increased, so that when the micro-vibration compaction molding machine 1 vibrates and compacts the red sand, the red sand is always higher than the sand frame 2. Then, the red sand higher than the sand frame 2 can be scraped off, so that repeated sanding and vibration compaction into the sand frame 2 is not required, and the casting of the sand mold can be completed at one time.

[0035] Secondly, by pulling the mounting bracket 701, the separation plate 702 can be moved. When the mounting bracket 701 is pulled forward, the separation plate 702 moves into the combined cover 4 and moves stably along the limiting groove 403. When the mounting bracket 701 moves backward, the separation plate 702 disengages from the combined cover 4. Thus, the mounting bracket 701 and the separation plate 702 can achieve the sealing and opening / closing effect of the bottom of the combined cover 4. Therefore, after the sand casting is completed, the separation plate 702 can be moved directly into the combined cover 4. At this time, the shovel groove 706 moves close to the top of the sand frame 2 to separate the red sand that is higher than the sand frame 2, so as to better remove the excess red sand. This can further improve the convenience of one-time sand casting in conjunction with the combined cover 4.

[0036] Finally, as the separation plate 702 moves into the combined cover 4, the mounting strip 703 and the conical block 704 work together to break up the red sand removed from the top of the sand frame 2, making it loose and easier to use later, thus further improving the performance of the combined cover 4.

[0037] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
