At the same time, the pouring material is wasted, which increases unnecessary production costs and is inconvenient for production operations.

[0031] As an improvement, Figures 1 to 5 As shown, the preferred embodiments of the present application are:

[0032] A gravity casting mold for a thermostat comprises a lower mold 1 and an upper mold 2.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the ejection mechanism 5 includes a double-axis motor 56 fixedly connected to one side of the lower mold 1, a circular hole 51 is opened on one side of the lower mold 1, and the inner wall of the circular hole 51 is rotatably connected to a first rotating rod 55 fixedly connected to the double-axis motor 56, a rectangular groove 53 is opened on the inner wall of the circular hole 51, and a rectangular hole 54 connected to the rectangular groove 53 is opened on the inner wall of the thermostat casting groove 3, a gear 57 is fixedly connected to the outer surface of the first rotating rod 55, and a rack 58 meshing with the gear 57 is slidably connected to the inner wall of the rectangular groove 53, a first inclined surface block 511 is fixedly connected to one side of the rack 58, and a rectangular block 59 is slidably connected to the inner wall of the rectangular hole 54, a second inclined surface block 512 is fixedly connected to the bottom of the rectangular block 59, and a first spring 510 is fixedly connected to the top of the second inclined surface block 512, and one end of the second inclined surface block 512 is fixedly connected to the inner wall of the rectangular groove 53.

[0034] Specifically, the first rotating rod 55 is rotated through the transmission of the dual-axis motor 56, and under the cooperation of the gear 57 and the rack 58, the first inclined block 511 squeezes the second inclined block 512, and then the rectangular block 59 is pushed out to separate the cast model from the lower mold 1, and manual removal is no longer required, thereby improving the casting efficiency, reducing the workload of the staff, and avoiding the problem of the staff being easily scalded by the lower mold 1 during the process of taking it, thereby facilitating use by users.

[0036] Specifically, the position of the rack 58 is limited by sliding the limit block 514 on the inner wall of the limit groove 513 as the rack 58 moves, thereby preventing the rack 58 from deviating from the moving position during the movement. The rack 58 can then always be meshed with the gear 57, thereby improving the operating stability of the rack 58.

[0037] like Figure 4 As shown, in this embodiment, the size and shape of the outer surface of the first bevel block 511 are consistent with the size and shape of the outer surface of the second bevel block 512 , and the first bevel block 511 is located below the second bevel block 512 .

[0038] Specifically, the first inclined surface block 511 will gradually squeeze the second inclined surface block 512 during the movement with the rack 58, so that the second inclined surface block 512 gradually moves upward, and then the second inclined surface block 512 can push the rectangular block 59 to slide on the inner wall of the rectangular hole 54, so that the rectangular block 59 can push the cast model, and then the cast model can be ejected from the lower mold 1.

[0039] like Figure 3 and Figure 5 As shown, in this embodiment, the vibration mechanism 6 includes a transmission shaft 64 fixedly connected to one side of the dual-axis motor 56, and the outer surface of the transmission shaft 64 is fixedly connected to a pulley group 63. A circular groove 61 is provided on the inner wall of the lower mold 1. The inner wall of the circular groove 61 penetrates and extends to one side of the lower mold 1 and is rotatably connected to a second rotating rod 62. The outer surface of the second rotating rod 62 is fixedly connected to the pulley group 63. The outer surface of the second rotating rod 62 is located in the inner cavity of the circular groove 61 and is fixedly connected to a second spring 65. The end of the second spring 65 away from the second rotating rod 62 is fixedly connected to a semicircular block 66.

A telescopic rod 67 is arranged inside the second spring 65, and the two ends of the telescopic rod 67 are respectively fixedly connected to the outer surface of the second rotating rod 62 and one side of the semicircular block 66.

[0040] Specifically, the second rotating rod 62 can be rotated through the transmission of the pulley group 63, and the telescopic rod 67 is driven to rotate during the rotation, so that the semicircular block 66 on the telescopic rod 67 can intermittently impact the impact groove 68 under the reaction force of the second spring 65, thereby generating vibrations on the lower mold 1, so that the pouring material in the pouring process can accelerate the flow rate. At the same time, the bubbles in the pouring material can be removed, so that the cast model is not easy to be missing, thereby improving the quality of the cast model and avoiding the waste of pouring materials.

[0041] The working principle of this application is:

[0042] Ejection mechanism steps:

[0043] When in use, the upper mold 2 is molded together with the lower mold 1, and the material to be poured is placed into the space formed by the upper mold 2 and the lower mold 1 through the pouring hole 4. When the poured material is formed, the upper mold 2 is moved away from the lower mold 1, and the dual-axis motor 56 is started, so that the first rotating rod 55 rotates on the inner wall of the circular hole 51, thereby driving the gear 57 to rotate. Since the gear 57 is meshed with the rack 58, the rotation of the gear 57 drives the rack 58 to move, and the limit block 514 slides on the inner wall of the limit groove 513 to limit it. During the movement, the rack 58 continuously pushes the first inclined surface block 511 to squeeze the second inclined surface block 512, so that the second inclined surface block 512 squeezes the rectangular block 59 to move upward, and squeezes the first spring 510 to be in a compressed state. As the rectangular block 59 moves upward, the cast model can be separated from the lower mold 1;

[0044] Due to the transmission of the dual-axis motor 56, the first rotating rod 55 rotates, and under the cooperation of the gear 57 and the rack 58, the first inclined surface block 511 squeezes the second inclined surface block 512, and then the rectangular block 59 is pushed out to separate the cast model from the lower mold 1, and no manual removal is required, thereby improving the casting work efficiency, reducing the workload of the staff, and avoiding the problem that the staff is easily burned by the lower mold 1 during the process of taking it, so as to facilitate the use of the user;

[0045] Since the limiting block 514 slides on the inner wall of the limiting groove 513 as the rack 58 moves, the position of the rack 58 is limited to prevent the rack 58 from deviating from the moving position during the movement, so that the rack 58 can always be meshed with the gear 57, thereby improving the running stability of the rack 58;

[0046] The first inclined surface block 511 gradually squeezes the second inclined surface block 512 during the movement with the rack 58, so that the second inclined surface block 512 gradually moves upward, and then the second inclined surface block 512 can push the rectangular block 59 to slide on the inner wall of the rectangular hole 54, so that the rectangular block 59 can push the cast model, and then the cast model can be ejected from the lower mold 1;

[0047] Vibration mechanism steps:

[0048] After the upper mold 2 and the lower mold 1 are molded together and the material is poured, the dual-axis motor 56 is started to drive the transmission shaft 64 to rotate. Under the transmission action of the pulley group 63, the second rotating rod 62 is driven to rotate, so that the telescopic rod 67 on the second rotating rod 62 rotates in the inner cavity of the circular groove 61. Under the reaction of the second spring 65, the semicircular block 66 can intermittently impact the impact groove 68 to generate vibration, thereby accelerating the flow rate of the poured material. The second rotating rod 62 can be rotated through the transmission of the pulley group 63, and the telescopic rod 67 is driven to rotate during the rotation process, so that the semicircular block 66 on the telescopic rod 67 can intermittently impact the impact groove 68 under the reaction force of the second spring 65, thereby generating vibration on the lower mold 1, so that the pouring material in the pouring process can accelerate the flow rate. At the same time, the bubbles in the pouring material can be removed, so that the poured model is not easy to be missing, the quality of the poured model is improved, and the pouring material is avoided. Waste.
