Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold capable of absorbing inserts. Background Art

[0002] A die-casting mold is a tool used in the die-casting process. It is crucial for manufacturing metal parts with complex shapes and high precision requirements. Molten metal is quickly injected into the die-casting mold cavity under high pressure, and the finished product is removed after it cools and solidifies. In the case of a die-casting part with an insert, existing die-casting molds set the insert on the movable mold assembly, then use the die-casting machine to drive the mold closed and inject molten metal into the cavity so that the molten metal wraps around the insert. After cooling, the molten metal and the insert are combined into one, completing the product molding. However, when designing a die-casting mold, the insert may be set on the fixed mold assembly. During the feeding process, the insert cannot be fixed to the side wall of the mold, so the insert is flushed out of its fixed position by the molten material, resulting in the inability to produce the product normally. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a die-casting mold capable of absorbing inserts in view of the current status of the existing technology.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figures 1 to 4 As shown, the utility model is a die-casting mold capable of adsorbing inserts, comprising:

[0025] Fixed mold assembly 1; movable mold assembly 2, movable mold assembly 2 and fixed mold assembly 1 are movably abutted against each other; product cavity 3, product cavity 3 is formed when the fixed mold assembly 1 and movable mold assembly 2 are abutted against each other, and product cavity 3 is used to provide space for product molding; positioning rod 4, positioning rod 4 is movably inserted into the fixed mold assembly 1, and can move between an extended state and a retracted state on the fixed mold assembly 1, and the moving direction is perpendicular to the opening direction of the die-casting mold.

[0026] Positioning rod 4 attracts and secures the insert. When the die-casting machine drives the movable mold assembly 2 and the fixed mold assembly 1 to close, positioning rod 4 extends into the product cavity 3, driving the insert fixed to the end of positioning rod 4 into the product cavity 3. The die-casting machine injects molten metal into the cavity. After cooling, the molten metal and the insert are tightly integrated, completing the product molding. Subsequently, positioning rod 4 switches from the extended state to the retracted state. The clamping force between the insert and the product is greater than the adsorption force between positioning rod 4 and the insert, causing positioning rod 4 to separate from the insert. The die-casting machine ejects the product from the die-casting mold, ensuring that the insert can be firmly installed on the side of the product.

[0027] The fixed mold assembly 1 of this solution is provided with a driving member 5, the output end of the driving member 5 is connected to the positioning rod 4, and the driving member 5 is used to drive the positioning rod 4 to move between the extended state and the retracted state.

[0028] The positioning rod 4 absorbs the insert and fixes it. The die-casting machine drives the movable mold assembly 2 and the fixed mold assembly 1 to close the mold. The driving member 5 drives the positioning rod 4 to move, and the positioning rod 4 drives the insert to extend into the product cavity 3.

[0029] After the product is formed, the driving member 5 drives the positioning rod 4 to switch from the extended state to the retracted state, and the positioning rod 4 moves and separates from the insert.

[0030] The positioning rod 4 of this solution is provided with an adsorption portion 410, and the adsorption portion 410 is provided with a magnet 6, which is used to fix the insert. The positioning rod 4 adsorbs the insert and fixes it. Subsequently, the die-casting machine drives the movable mold assembly 2 and the fixed mold assembly 1 to close the mold. The driving member 5 drives the positioning rod 4 to move, so that the positioning rod 4 drives the insert to extend into the product cavity 3. The die-casting machine injects molten metal into the product cavity 3, and the molten metal contacts the insert and applies a thrust to the insert. In order to prevent the insert from moving, the magnet 6 magnetically attracts the insert to ensure that the insert is firmly fixed on the positioning rod 4, thereby ensuring that the product can be smoothly formed and avoiding product scrapping due to insert displacement.

[0031] The magnets 6 of this embodiment are cylindrical and are provided in four numbers. The axes of the four magnets 6 are distributed in a rectangular shape on the adsorption portion 410. The rectangular distribution of the axes of the four magnets 6 on the adsorption portion 410 allows the magnets 6 to evenly apply force to each part of the insert when fixing the insert, thereby making the magnets 6 more stable when fixing the insert.

[0032] The adsorption portion 410 of this embodiment is provided with through slots 411 for accommodating magnets 6. Four through slots 411 are provided, and the axes of these four through slots 411 are distributed in a rectangular shape on the adsorption portion 410. Four magnets 6 are respectively disposed in these four through slots 411, enabling the adsorption portion 410 to secure the insert.

[0033] The positioning rod 4 of this embodiment is provided with a connecting portion 420, one end of which is connected to the output end of the driver 5, and the end of the connecting portion 420 away from the driver 5 is threadedly connected to the adsorption portion 410. The end of the connecting portion 420 abuts against the magnet 6 to limit the position of the magnet 6. When the magnet 6 is installed on the positioning rod 4, if the through-slot 411 is long, the suction force on the magnet 6 during installation will increase, making it more difficult to install the magnet 6 in place. In order to avoid the problem that the magnet 6 is difficult to install due to the through slot 411 being too long, the positioning rod 4 is designed to be composed of two parts: a connecting part 420 and an adsorption part 410. The magnet 6 is installed in the through slot 411. Since the through slot 411 is only provided on the adsorption part 410 and is shorter than the entire positioning rod 4, the magnet 6 is subjected to a smaller suction force when being installed into the through slot 411, so that the magnet 6 can be more easily installed into the through slot 411. At the same time, the connecting part 420 is responsible for connecting the adsorption part 410 and the driving part 5. The end of the connecting part 420 abuts against the magnet 6 and acts as a limiter for the magnet 6 to prevent the magnet 6 from being misplaced during installation.

[0034] The driving part 5 of this solution is set as a cylinder 510, the positioning rod 4 absorbs the insert and fixes it, the die-casting machine drives the movable mold assembly 2 and the fixed mold assembly 1 to close the mold, the cylinder 510 drives the positioning rod 4 to move, and the positioning rod 4 drives the insert to extend into the product cavity 3.

[0035] After the product is formed, the oil cylinder 510 drives the positioning rod 4 to move from the extended state to the retracted state, and the positioning rod 4 moves and separates from the insert. The oil cylinder 510 can accurately control the movement of the positioning rod 4 and make its movement more stable.

[0036] The insert is held in place by positioning rods 4, located on the side of the fixed die assembly 1. When the die-casting machine closes the movable die assembly 2 and the fixed die assembly 1, the positioning rods 4 extend into the product cavity 3, and the die-casting machine injects molten metal into the product cavity 3, enveloping the insert. After cooling, the molten metal and the insert are tightly integrated, completing the product. The positioning rods 4 then retract, and the die-casting machine ejects the product from the die-casting mold, ensuring the insert is securely installed in the side of the product.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature.
