[0001] The utility model relates to the technical field of casting devices, in particular to a casting device with an anti-deformation function. Background Art

[0002] Casting is the process of pouring liquid metal into a casting cavity that matches the shape of the part. After it cools and solidifies, a metal part blank with a certain shape, size and performance is obtained. The raw materials for casting can be monomers, slurries that have undergone preliminary polymerization or condensation, or solutions of polymers and monomers.

[0003] In the prior art, the prepared casting raw materials are injected into the upper and lower molds which are tightly closed, and solidified to obtain a product similar to the mold cavity;

[0004] Although the existing technical solution performs casting by closing the upper and lower molds, when the metal casting casting mold is actually closed, the mold closing tightness is general, and shaking or deviation may occur, causing deformation of the cast metal parts. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution:

[0026] See also Figures 1 to 3 A casting device with an anti-deformation function comprises a cooling shell 1, a lower mold 2 is arranged at the lower part of the cooling shell 1, an upper mold 3 is arranged above the lower mold 2, and fastening mechanisms 4 are arranged on both sides of the outer wall of the cooling shell 1; the fastening mechanism 4 comprises a fixed shell 401, the fixed shell 401 is embedded on both sides of the outer wall of the cooling shell 1, an electromagnet 402 is fixed on one side of the inner part of the fixed shell 401, a spring 403 is fixed on the outer wall of the electromagnet 402, and a permanent magnet block 404 is connected to the end of the spring 403 away from the electromagnet 402, and the fixed shell 40 A penetration groove 405 is provided on the outer wall corresponding to the position of the permanent magnet block 404, and a conical block 406 is connected to one end of the permanent magnet block 404 away from the spring 403. Limiting grooves 407 are provided on both sides of the outer wall of the upper mold 3 corresponding to the positions of the conical block 406. The permanent magnet block 404 forms an elastic structure with the electromagnet 402 through the spring 403, and the permanent magnet block 404 forms a sliding structure with the fixed shell 401 through the spring 403. The four corners of the bottom end of the upper mold 3 are fixed with penetration rods 5, and a limiting hole 6 is provided at the top end of the lower mold 2 corresponding to the position of the penetration rod 5.

[0027] By adopting the above technical scheme, first, when the lower mold 2 and the upper mold 3 are closed, the insertion rod 5 is inserted into the limiting hole 6 to perform preliminary limiting to avoid deviation and deformation of the material. Then, when the lower mold 2 and the upper mold 3 slide down along the cooling shell 1, the spring 403 elastically pushes the permanent magnet block 404 to pass through the fixing shell 401 through the passing groove 405 and enter the limiting groove 407 to limit the upper mold 3 to avoid shaking, which causes deformation of the casting material. The conical block 406 facilitates the sliding of the lower mold 2 and the upper mold 3. When demolding, the permanent magnet block 404 is magnetically attracted by the electromagnet 402, thereby compressing the spring 403 to allow the permanent magnet block 404 to disengage from the limiting groove 407, so that the upper mold 3 can be disassembled and assembled.

[0028] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a refrigeration plate 7 is embedded below the outer wall fixed shell 401 of the cooling shell 1, a mounting shell 8 is fixed to the bottom end of the cooling shell 1, a driving mechanism 9 is arranged inside the mounting shell 8, and the driving mechanism 9 includes a motor 901, and the motor 901 is mounted on one side of the inside of the mounting shell 8, a worm 902 is connected to the power output end of the motor 901, and a worm wheel 903 is connected to one side of the outer wall of the worm 902, and the driving mechanism 9 also includes a threaded rod 904, and the threaded rod 904 is fixed inside the worm wheel 903, and a support rod 905 is fixed on one side of the threaded rod 904 at the bottom end of the lower mold 2, and the threaded rod 904 is threadedly connected to the lower mold 2, and a sliding structure is formed between the threaded rod 904 and the lower mold 2.

[0029] By adopting the above technical solution, the motor 901 drives the worm 902 to drive the worm wheel 903 to rotate, so that the threaded rod 904 rotates, and the motor 901 controls the lower mold 2 to slide along the cooling shell 1, so that the lower mold 2 and the upper mold 3 enter the interior of the cooling shell 1, and the permanent magnet block 404 penetrates the limiting groove 407, so that the coolant whose temperature is reduced by the refrigeration plate 7 can cool the lower mold 2 and the upper mold 3, thereby improving the solidification efficiency of the material. At the same time, when the permanent magnet block 404 penetrates the limiting groove 407, the motor 901 drives the lower mold 2 to rise and form a clamping force with the permanent magnet block 404, so as to achieve stability, and cooperate with the support rod 905 to facilitate the sliding of the lower mold 2.

[0030] Working principle: When the lower mold 2 and the upper mold 3 are closed by the insertion rod 5 and the limiting hole 6, shaking and deviation are avoided. At the same time, the permanent magnet block 404 is elastically pushed by the spring 403, passes through the fixed shell 401 through the penetration groove 405, and enters the limiting groove 407 to limit the upper mold 3 to avoid loosening and separation. After the electromagnet 402 is started, the permanent magnet block 404 is magnetically attracted to compress the spring 403, which is convenient for the upper mold 3 to be separated, and the permanent magnet block 404 is convenient for the lower mold 2 and the upper mold 3 to be attached to the tapered block 406. The mold 3 slides, and the motor 901 embedded in the mounting shell 8 drives the worm 902, thereby pushing the worm wheel 903 to drive the threaded rod 904 to rotate, thereby pushing the lower mold 2 to rise and cooperate with the permanent magnet block 404, so that the lower mold 2 and the upper mold 3 are clamped to avoid loosening and causing deformation of the material, and cooperate with the support rod 905 to keep the lower mold 2 stable when moving. When the lower mold 2 and the upper mold 3 enter the cooling shell 1, the temperature of the coolant inside the cooling shell 1 is reduced by the refrigeration plate 7, so that the material can be quickly formed and easy to demold.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
