Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 In this embodiment of the present invention, a multi-cavity casting precision mold includes an upper mold mechanism and a lower mold mechanism; wherein the upper mold mechanism includes a top mold base 1 with a casting port 14 at the top, and an upper main mold 2 is fixed to the bottom of the top mold base 1 by bolts; a rectangular cavity is provided in the middle of the upper main mold 2, and a casting inner mold 15 is installed in the cavity; upper mold cores 16 are fixed at the four corners of the bottom of the casting inner mold 15; the upper mold cores 16 are embedded in the upper fixed mold base 3 and the upper cavity mold 4; the fixed mold base 3 and the upper cavity mold 4 are fixed by bolts; the casting port 14 is fitted and connected to the mold opening of the casting inner mold 15;

[0027] The lower mold mechanism includes a lower mold 5 that is closed with the upper mold 4. A lower mold base 18 is fixed to the bottom of the lower mold 5. Four lower mold cores 20 corresponding to the upper mold core 16 are embedded in the lower mold base 18 and the lower mold 5.

[0028] By adopting the above technical solution, during use, the upper mold mechanism and the lower mold mechanism are closed, and when closed, the upper mold core 16 and the lower mold core 20 form a closed cavity. Molten metal is poured in from the casting port 14, and the molten metal enters the cavity formed by the upper mold core 16 and the lower mold core 20 along the inner casting mold 15. Since there are four sets of mold cores 16 and lower mold cores 20, four products can be formed simultaneously during casting. This effectively improves the company's production efficiency and saves the company's production costs.

[0029] In this embodiment, the lower mold base 18 and the lower cavity mold 5 are slidably connected to the guide post 19 at their four corners; the guide post 19 is fixed to the pad 6; and springs 9 are also provided at the four bottom corners of the lower mold base 18.

[0030] By adopting the above technical solution, the spring 9 has a certain buffering effect during the mold closing process, which can avoid the situation of mold damage caused by hard contact.

[0031] Furthermore, the pad 6 is provided in two sets, which are respectively fixed to the two sides of the upper end of the base 7 by countersunk bolts. Multiple sliding pillars are provided above the base 7, wherein the lower mold base 18 is slidably connected to the sliding pillars, and the spring 9 is sleeved on the sliding pillars.

[0032] The sliding column can guide the lower mold base 18, ensuring that it does not deflect during the buffering process and ensuring the stability of the mold operation.

[0033] In this embodiment, two rectangular slots are provided on both sides of the lower mold base 18, and two guide frames 10 are fixed in the rectangular slots; two T-shaped sliders 11 are fixed on both sides of the upper cavity mold 4 and the lower cavity mold 5; the sliders 11 are slidably connected in the slide grooves in the guide frames 10.

[0034] By adopting the above technical solution, since the requirements for precision molds are very strict during the casting process, we set the slider 11 to slide along the guide frame 10 to guide and limit the movement of the upper mold mechanism, so as to avoid misalignment or misalignment of the upper mold mechanism and the lower mold mechanism during the mold opening or closing process. This can effectively ensure the accuracy of the upper mold mechanism and the lower mold mechanism when closing, thereby ensuring that the dimensions of the cast product are more accurate.

[0035] In this embodiment, an electromagnet 12 is fixed to one side of the upper main mold 2 by bolts.

[0036] During the casting process, some impurities or foreign objects may be mixed into the liquid metal. If these impurities or foreign objects enter the mold cavity, they will affect the quality of the cast product.

[0037] By adopting the above technical solution, the electromagnet 12 is set in the upper mold main mold 2, so that the upper mold main mold 2 and the casting inner mold 15 have a certain magnetism; the electromagnet 12 can be energized before or during casting to generate magnetic force to adsorb ferromagnetic impurities or foreign objects in the liquid metal, thereby purifying the liquid metal and reducing defects and flaws in the product.

[0038] In this embodiment, after the upper mold mechanism and the lower mold mechanism are closed, a magnet 13 is provided on one side of the upper fixed mold base 3, the upper cavity mold 4, the lower cavity mold 5 and the lower mold base 18.

[0039] By adopting the above technical solution, in order to further ensure the accuracy of the upper fixed mold base 3, upper cavity mold 4, lower cavity mold 5 and lower mold base 18 when the mold is closed, the closing effect of the upper fixed mold base 3, upper cavity mold 4, lower cavity mold 5 and lower mold base 18 is enhanced by setting the magnet 13.

[0040] The upper main mold 2, upper fixed mold base 3, upper cavity mold 4, lower cavity mold 5, and lower mold base 18 are all equipped with cooling pipes 17. The mold can be cooled through the cooling pipes 17. After casting is completed, cold water is introduced into the cooling pipes 17 to cool the product, thereby enabling rapid molding of the product.

[0041] The working principle of this utility model is as follows: During use, the upper mold mechanism and the lower mold mechanism are closed. The slider 11 slides along the guide frame 10 to guide and limit the movement of the upper mold mechanism, preventing misalignment or misfitting during mold opening or closing. This effectively ensures the accuracy of the upper and lower mold mechanisms when closing, thus guaranteeing more precise dimensions of the cast product. When closed, the upper mold core 16 and the lower mold core 20 form a closed cavity. Iron 12 can be energized before or during casting to generate magnetic force that adsorbs ferromagnetic impurities or foreign objects in the liquid metal, thus purifying the liquid metal and reducing defects and flaws in the product. The molten metal is poured into the casting port 14 and flows along the inner casting mold 15 into the cavity formed by the upper mold core 16 and the lower mold core 20. Since there are four sets of mold cores 16 and 20, four products can be formed simultaneously during casting, effectively improving the company's production efficiency and saving production costs.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
