Problems solved by technology

The feeding method of the traditional die-casting process is from one side of the product to the other. This feeding method is suitable for parts with simple structure and small size, but for parts with complex structure and large size, due to the casting process flow The long side is long, the material properties of the near-end and far-end products are significantly different, and the far-end usually does not meet the design requirements

Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] see Figure 1-7 , this embodiment provides a center-feed die-casting mold suitable for large-sized parts, including a movable mold 10, a fixed mold 11 and a mold core 12, and the mold core 12 is arranged between the movable mold 10 and the fixed mold 11. The mold also includes: a runner module 13, which is arranged on the fixed die 11, and includes a plurality of runners opened on the fixed die and the die core, so that the pouring liquid can be fed from multiple points; the cutting module 14 is arranged on the fixed die. Above the runner, used to extrude and cut the formed product; the cooling module 15 is arranged in the runner and used to cool the runner; wherein, the runner on the fixed die starts from the center of the fixed die along a straight line Spaced or circumferentially spaced.

[0021] Specifically, the runner mod...

Abstract

The center feeding die-casting die comprises a movable die body, a fixed die body and a die core, the die core is arranged between the movable die body and the fixed die body, the center feeding die-casting die further comprises a runner module arranged on the fixed die body, and the runner module is arranged between the movable die body and the fixed die body. Comprising a plurality of runners formed in a fixed mold and a mold core, so that pouring liquid can be fed from multiple points; the cut-off module is arranged above the runner of the fixed mold and is used for extruding and cutting off the formed product and the runner; the cooling module is arranged in the flow channel and is used for cooling the flow channel; and the runners on the fixed mold are linearly formed at intervals or circumferentially formed at intervals from the center position of the fixed mold. By adopting a central feeding mode, the flow length of products is reduced, the performance requirement for large-size die castings is met, and the consistency of the products is improved.

Description

technical field [0001] The invention relates to the technical field of die-casting equipment, in particular to a center-feed die-casting mold suitable for large-sized parts. Background technique [0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal by using the inner cavity of the mold. It is suitable for mass production of light metal castings. Die casting is the most widely used process in various casting processes. The feeding method of the traditional die-casting process is fed from one side of the product to the other end. This feeding method is suitable for parts with simple structure and small size, but for parts with complex structure and large size, due to the flow of the casting process. The long side is long, the material properties of the proximal and distal products are significantly different, and the distal end usually does not meet the design requirements.
