Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to a bridging casting equipment for M-shaped castings. Background Technology

[0002] Because of the significant height difference between the internal and external structures of M-type castings, during the normal pouring process using traditional methods, the large structural height difference causes the molten metal to roll downwards along with the casting structure when it reaches the highest point. During this downward roll, air and sand are easily trapped, ultimately leading to casting defects such as porosity or sand loss, or even scrapping the casting, thus affecting the casting yield and production efficiency. Utility Model Content

[0003] In view of the problems existing in the bridging casting equipment for the above-mentioned M-type castings, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a bridging casting device for M-type castings, which solves the problem that the existing bridging casting device for M-type castings is prone to casting defects such as porosity or sand loss, and may even cause the castings to be scrapped, affecting the casting yield and production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bridging casting device for an M-shaped casting includes a casting shell and a partition plate. The casting shell has a cavity in its center, and through slots are formed on both sides of the cavity's center. The partition plate is slidably disposed within the corresponding through slot. One end of the partition plate has an inclined surface with the same inclination as the side of the cavity near the through slot. One end of the partition plate abuts against the inner wall of the cavity. A fixed shell is provided on one side of the casting shell, and a sliding plate is provided on another side. Insert rods are fixedly mounted at both ends of the sliding plate on the side near the casting shell. Insertion holes are formed on both sides of one end of the partition plate, and one end of each insertion rod is inserted into a corresponding insertion hole. A limiting mechanism restricting the movement of the sliding plate is provided inside the fixed shell.

[0007] Preferably, the limiting mechanism includes sliders and stops. The two sliders are slidably disposed on both sides of the temporal portion of the fixed shell, and the two stops are fixedly disposed on the opposite side of the two sliders. One end of each of the two stops extends to the outside of the cavity, and the outer end of each of the two stops abuts against the side of the slide away from the casting shell.

[0008] Preferably, a sliding rod is fixedly provided on one side of the inner side of the fixed shell, and one end of each of the two sliders is movably sleeved with the wall of the sliding rod.

[0009] Preferably, a spring is movably sleeved on the wall of the slide rod, and the two ends of the spring are respectively fixedly connected to the corresponding slider.

[0010] Preferably, the thickness of the partition is the same as the depth of the cavity.

[0011] Preferably, the cross-section of the fixed shell is rectangular.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This invention, by setting baffles on both sides of the middle part of the mold cavity, enables the molten metal to fill the mold smoothly during the pouring process. After half of the mold cavity is poured, the stop block is pushed into the fixed shell, and then the slide is pulled away from the pouring shell to separate the insert rod from the insertion hole, so that the baffle can be pulled out. Then, the other end of the baffle is inserted into the through groove so that the inclined surface of the baffle is aligned with the inclined surface of the mold cavity. Then the baffle is fixed, and the pouring work of the other half of the mold cavity can continue. This invention can effectively solve the casting defects of M-type castings and improve the product yield and production efficiency. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a bridging casting device for M-shaped castings.

[0022] Reference Figure 1-3 A bridging casting device for M-shaped castings includes a casting shell 1 and a partition plate 2. A cavity 9 is formed in the middle of the casting shell 1, and through grooves are formed on both sides of the middle end of the cavity 9. The partition plate 2 is slidably disposed inside the corresponding through groove. One end of the partition plate 2 abuts against the inner wall of the cavity 9. The thickness of the partition plate 2 is the same as the depth of the cavity 9, which can effectively block the molten metal. One end of the partition plate 2 is provided with a slope, and the slope is the same as the inclination of the side of the cavity 9 near the through groove. A fixed shell 4 is provided on one side of the casting shell 1. A sliding plate 3 is provided on one side of the casting shell 1. Insert rods 10 are fixedly provided at both ends of the sliding plate 3 near the side of the casting shell 1. Insertion holes are formed on both sides of one end of the partition plate 2, and one end of the insertion rod 10 is inserted into the corresponding insertion hole.

[0023] Reference Figure 1-3 The fixed shell 4 is provided with a limiting mechanism to restrict the movement of the slide plate 3. The limiting mechanism includes a slider 5 and a stop 8. The two sliders 5 are slidably disposed on both sides of the temporal part of the fixed shell 4. The two stops 8 are fixedly disposed on the opposite side of the two sliders 5. One end of each stop 8 extends to the outside of the cavity. The outer end of each stop 8 abuts against the side of the slide plate 3 away from the casting shell 1.

[0024] Reference Figure 1-3 A sliding rod 6 is fixedly installed on one side of the inner side of the fixed shell 4. One end of each of the two sliders 5 is movably connected to the wall of the sliding rod 6, so that the sliders 5 cannot rotate, that is, they can slide stably. A spring 7 is movably connected to the wall of the sliding rod 6. The two ends of the spring 7 are fixedly connected to the corresponding sliders 5, so that the sliders 5 can be reset. The cross-section of the fixed shell 4 is rectangular, so that the sliding plate 3 cannot rotate, that is, it can slide stably.

[0025] In this invention, during use, partition plates 2 are provided on both sides of the middle part of the cavity 9, which can make the molten metal fill the mold smoothly during the pouring process. After completing half of the pouring work of the cavity 9, the stop block 8 is pushed into the fixed shell 4, and then the slide plate 3 is pulled away from the pouring shell 1, so that the insert rod 10 is separated from the insertion hole, and the partition plate 2 can be pulled out. Then, the other end of the partition plate 2 is inserted into the through groove, so that the inclined surface of the partition plate 2 is aligned with the inclined surface of the cavity 9. Then the partition plate 2 is fixed, and the other half of the cavity 9 can continue to be poured. This can effectively solve the casting defects of M-type castings and improve the product yield and production efficiency.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
