Description

Technical Field

[0001] The utility model relates to the technical field of die-casting dies suitable for producing shell products with complex structures, and in particular to a die-casting dies suitable for producing shell products with complex structures. Background Art

[0002] In the die-casting process, it is usually necessary to heat the mold after opening it. After the mold is opened, the aluminum alloy or other metal materials in the mold will quickly cool and solidify. If no heating treatment is performed, the mold may be damaged or deformed when the mold is closed again due to the increased hardness of the metal material, affecting the quality of the product and production efficiency. Therefore, the mold usually needs to be heated after opening the mold to return the mold to a working temperature suitable for die-casting again, to ensure that the mold can operate normally and ensure the quality of product molding. However, when the existing die-casting molds for complex structure shell products are in use, when the mold is opened, the cooling water is always in a flowing state, the heat escapes, and it needs to be heated again later, which increases the production cost. For example, a Chinese patent discloses "a kind of automobile transmission The invention discloses a "die-casting mold structure for a device shell", and its application number is: "CN201420190949.8", which includes a movable mold frame, a fixed mold frame, a fixed mold core and a movable mold core. The mold cavity includes a deep cavity and a shallow cavity. The pouring port is aligned with the deep cavity. An integral melting cup and a small melting cup are arranged in the pouring port. The small melting cup is connected with the deep cavity. A fixed mold core is arranged on the fixed mold frame. An angle is formed between the fixed mold core and the vertical surface of the pouring port. The stretching direction of the mold cavity is consistent with the length direction of the fixed mold core. The above structure is convenient for use, but it is not convenient to reduce the dissipation of heat when in use. It needs to be heated again when the mold is closed again, which increases the production cost and has limitations when used. Utility Model Content
