Description

Technical Field

[0001] The utility model relates to the field of die-casting equipment, in particular to a die-casting equipment capable of rapid cooling. Background Art

[0002] Die casting is a processing technology that injects molten metal into a metal mold and then quickly cools it under high pressure to form it. This method can produce complex geometric shapes and can quickly manufacture a large number of precise parts. Die casting is often used to produce various industrial parts such as automotive accessories, electronic equipment parts, and household appliances. In the specific die-casting process, the molten metal is injected into the mold through a nozzle or a gate, and then cooled and formed under high pressure. At present, in the die-casting process, cooling water is usually continuously injected into the inner cavity of the mold. After the mold is closed, the metal liquid injected into the mold is cooled to accelerate the cooling and forming of the workpiece. The existing cooling water is continuously infused into the inner cavity of the mold. Since no cooling is required in the open mold state, but the cooling water is still supplied uninterruptedly, it will cause a waste of cooling water and is not environmentally friendly. Utility Model Content

[0003] The purpose of the utility model is to provide a die-casting device that can be cooled quickly in order to solve the above-mentioned problem. A sealing component for controlling the opening and closing state of the bottom opening of the cooling chamber is arranged inside the fixed mold base, and a transfer box connected to the fixed mold base is arranged below the sealing component. The cooling water supply channel is automatically closed when the mold is opened to save coolant when cooling is not required, and the bottom opening of the cooling chamber is automatically opened after the mold is closed, which is more environmentally friendly. See the following description for details.

[0014] Preferably, a longitudinally extending mounting plate is fixed to the outer side of the guide rod, and a die-casting cylinder for supporting and driving the movable die base to move laterally is fixed to the outer side of the mounting plate.

[0015] The beneficial effect is that: the utility model arranges a sealing component for controlling the opening and closing state of the bottom opening of the cooling cavity inside the fixed mold base, and arranges a transfer box connected to the fixed mold base below the sealing component, so that the cooling water supply channel is automatically closed when the mold is opened, so as to save coolant when cooling is not required, and automatically opens the bottom opening of the cooling cavity after the mold is closed, which is more environmentally friendly;

[0016] In addition, when the bottom of the cooling chamber is closed, the transfer chamber can be used to temporarily store cooling water, and by continuously injecting water into the transfer chamber to compress the compression spring, the cooling chamber can be quickly filled with cooling water by pushing the piston plate through the compression spring when the cooling chamber is opened by closing the mold, thereby improving the cooling efficiency and ensuring the consistency of the cooling speed of the upper and lower parts of the cooling chamber, and having strong practicality.
