Description

Technical Field

[0001] This utility model relates to the field of aluminum die casting technology, and in particular to a rapid cooling aluminum die casting mold. Background Technology

[0002] Die casting is a type of pressure-cast part. It is made by using a pressure casting machine equipped with a casting mold. Molten metals such as copper, zinc, aluminum, or aluminum alloys are poured into the feed port of the die casting machine and then die-cast to produce copper, zinc, aluminum, or aluminum alloy parts with shapes and sizes limited by the mold. Such parts are usually called die castings. For aluminum die casting, the mold has a customized shape cavity, and the die casting machine injects molten aluminum into it under high pressure.

[0003] To this end, patent No. 201920657749.1 discloses a forming mold for large flat aluminum die castings, including an upper mold and a lower mold. The upper mold includes an upper mold fixing plate and an upper mold base located below the upper mold fixing plate. An upper mold base plate is installed below the upper mold base. A first waist-shaped hole is opened in the middle of the upper mold base plate. Multiple upper modules are installed on the lower surface of the upper mold base plate at intervals. The lower mold includes a lower mold fixing plate and a lower mold base located above the lower mold fixing plate. A connecting plate is provided between the lower mold fixing plate and the lower mold base. A lower template is installed above the lower mold base. Multiple lower modules, each matching the upper modules, are installed on the upper surface of the lower template. The multiple upper modules and multiple lower modules cooperate to form a forming mold. This utility model provides a forming mold for large flat aluminum die castings, which has advantages such as accurate positioning, high forming efficiency, and long mold service life.

[0004] The existing technical solutions described above have the following drawbacks: Although the positioning holes at both ends of the upper mold fixing plate, and the positioning sleeves on the positioning holes that match the positioning guide pillars, improve positioning accuracy, shape efficiency, and mold life, traditional aluminum die casting mold cooling technology mainly relies on conventional cooling water channel design and uses room temperature water as the cooling medium. This cooling method has many disadvantages: On the one hand, the cooling water channel layout is difficult to completely fit the complex shape of the casting contour, resulting in uneven local cooling of the mold, which can easily cause defects such as shrinkage cavities and deformation in the casting; on the other hand, room temperature water has limited cooling efficiency and a long cooling time, which prolongs the die casting cycle and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a fast-cooling aluminum die-casting mold to solve the problem that existing fast-cooling aluminum die-casting molds mainly rely on conventional cooling water channel designs, resulting in low production efficiency and uneven cooling.

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.

[0035] Please see Figures 4-5 This utility model provides a rapid cooling aluminum die-casting mold, comprising:

[0036] Main components: The main components include a lower mold 11, an upper mold 12, and an injection port 13;

[0037] The upper mold 12 is installed above the lower mold 11, and the injection port 13 is opened at the top of the upper mold 12;

[0038] The main components also include template 14;

[0040] The lower mold 11 and the upper mold 12 are used to provide space for the installation and replacement of the template 14, and the upper mold 12 is used to open the injection port 13;

[0041] In this process, the cast metal is melted in a separate furnace before being fed into the cold chamber machine. Then, the machine uses a pressurized plunger to press the molten metal into the mold body through the injection port 13.

[0042] All of the above parts are existing technologies;

[0043] Cooling assembly: The cooling assembly includes a connection slot 21, a mounting bracket 22, and a water storage tank 23;

[0044] The connecting groove 21 is opened on both sides of the outer wall of the upper mold 12, the mounting bracket 22 is slidably connected to both sides of the outer wall of the upper mold 12, and the water storage tank 23 is fixedly connected to the outside of the mounting bracket 22;

[0045] The cooling assembly also includes a water sprayer 24 and a connecting block 25;

[0046] The water sprayer 24 is fixedly connected to the front end of the water storage tank 23, and the connecting block 25 is fixedly connected to both sides of the inner wall of the mounting bracket 22.

[0047] The connecting groove 21 provides space for the connecting block 25 to slide. The water pump in the sprayer 24 draws water from the water storage tank 23 and uses pressure to spray the water out through the nozzle, forming fine water droplets or mist.

[0048] With the auxiliary cooperation between the water storage tank 23 and the water sprayer 24, the water spray range of the water sprayer 24 can be adjusted by sliding the connecting block 25 along the trajectory of the connecting groove 21.

[0049] Working principle: When the operator cools the mold;

[0050] First, by starting the water sprayer 24, the water pump in the water sprayer 24 can draw water from the water storage tank 23 and use pressure to spray the water out through the nozzle, so that the formed mist water droplets are sprayed on the upper mold 12, and the rapid cooling is achieved by absorbing heat through the evaporation of the mist droplets.

[0051] Next, by sliding the mounting bracket 22 upward, the connecting block 25 installed inside the mounting bracket 22 can slide along the trajectory of the connecting groove 21. When the connecting block 25 slides to the turning point of the connecting groove 21, the mounting bracket 22 can be flipped horizontally downward while the mounting bracket 22 is slid horizontally to adjust the spraying range of the water sprayer 24.

[0052] This step allows for rapid cooling of the mold, making it easier for workers to remove the formed aluminum die castings and improving the efficiency of aluminum die casting production.

[0053] Please see Figure 2-3 As shown, this embodiment, based on the above embodiment, also includes a replacement component;

[0054] The replacement components include a slide 31, a spring clip 32, and a protective plate 33;

[0055] The slide groove 31 is formed on the outer side of the lower mold 11, the spring buckle 32 is fixedly connected to the outer side wall of the lower mold 11, and the protective plate 33 is slidably connected to the inside of the slide groove 31.

[0056] The replacement components also include mounting slot 34, movable block 35, and limiting hole 36;

[0057] Mounting grooves 34 are formed on both sides of the outer wall of the protective plate 33, movable blocks 35 are slidably connected to the inside of mounting grooves 34, and limiting holes 36 are formed on the inner wall of mounting grooves 34.

[0058] The slide groove 31 is used to provide sliding space for the protective plate 33. The spring buckle 32 and the limiting hole 36 are engaged. The protective plate 33 is used to open the mounting groove 34. The mounting groove 34 is used to open the limiting hole 36. The mounting groove 34 is used to provide sliding space for the movable block 35.

[0059] With the auxiliary cooperation between the slide 31 and the spring buckle 32, the two sets of templates 14 can be picked up and replaced while the protective plate 33 is slid upward;

[0060] Working principle: When the staff uses the mold;

[0061] First, by sliding the movable block 35 inside the sliding mounting groove 34, the movable block 35 can slide upward and press the spring buckle 32 that is engaged in the limiting hole 36, thereby releasing the limiting between the spring buckle 32 and the lower mold 11.

[0062] Next, by sliding the protective plate 33 downwards, the protective plate 33 can slide down along the track of the slide groove 31, which can remove the obstruction formed on one end of the lower mold 11 and the upper mold 12, thereby allowing the template 14 installed in the lower mold 11 and the upper mold 12 to be removed and replaced.

[0063] This step can help workers replace the molded template 14 according to the actual casting specifications.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
