Existing die-casting molds use a method of pouring and filling the cavity on one side, while providing a slag bag and exhaust duct on the other. This results in poor filling quality and mold temperature balance. The uneven distribution of the runner and slag bag also leads to product deformation during mold opening and ejection.

[0015] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0016] A kind of Figure 1-3 The die-casting mold for a deformable frame shown includes a fixed mold 1 and a movable mold 2, with a product cavity 8 defined between the movable mold 2 and the fixed mold 1. A sprue bushing 3 is provided on the fixed mold 1, a diverter cone 4 is provided on the movable mold 2, and a sprue 5 and a runner 6 are provided on one side of the fixed mold 1. A horizontally movable slider 13 is provided on the movable mold 2, with the diverter cone 4 positioned on the slider 13, and the runner 6 is positioned above the slider 13. The runner 6 extends to the center of the core of the movable mold 2. A branch runner 7 is provided on the core of the movable mold 2, connecting to the runner 6. The branch runner 7 radiates outwardly to the product cavity 8, filling the product cavity by radiating outward from the periphery of the intermediate phase. This reduces the path of molten metal in the cavity, thereby improving die-casting quality. Multiple first slag lumps 9 are provided on the core of the movable mold 2, distributed outside the product cavity 8. The outer sides of the first slag lumps 9 are connected to an exhaust channel 11 for slag collection and exhaust. Inside the product cavity 8, a second slag bag 10 is located. The first slag bag 9 corresponds to the branch runner 7 or the second slag bag 10. This second slag bag 10 is a balancing slag bag. It is primarily cylindrical, with a diameter of approximately 10 mm, a thickness of approximately 20 mm, and a draft angle of 10°-15°. The purpose of this balancing slag bag is to ensure that the forces on both sides of the product are equalized during mold opening, thereby reducing product deformation.

[0017] Furthermore, the product cavity 8 has a concave portion on the side of the movable mold 2, and a first slag bag 9 and a second slag bag 10 are distributed on both sides of the concave portion. This structure makes the product less likely to deform when ejected from the mold and has good die-casting quality.

[0018] In order to ensure smooth demoulding of the product and prevent it from being deformed during demoulding, a plurality of elastic ejector rods 12 are provided on one side of the fixed mold 1 of this embodiment. The elastic ejector rods 12 are evenly distributed at the four corners of the product cavity 8, and at least one-half of the front end surface of the elastic ejector rods 12 is in contact with the mold core surface of the movable mold 2. When the mold is closed, the elastic ejector rods 12 are retracted into the static mold under the action of the clamping force of the movable mold core. When the mold is opened, the elastic ejector rods are automatically ejected due to the action of the spring, helping the product to be demoulded from the static mold.

[0019] The movable mold 2 is equipped with multiple ejector pins, which are evenly distributed on the bottom surfaces of the branch runner 7, the product cavity 8, the first slag bag 9, and the second slag bag 10. This structure ensures uniform ejection force on the product, minimizes product deformation, and increases product yield.

[0020] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
