Description

Technical Field

[0001] The utility model relates to the technical field of die casting molds, in particular to a die casting mold. 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. Existing die-casting molds are used to form products with holes by setting core pullers. When the fixed mold assembly is separated from the movable mold assembly, a cylinder is required to drive the core puller out of the hole. However, due to the large clamping force between the core puller and the hole, a cylinder with larger tonnage and volume must be used to drive the core puller. The larger the cylinder volume, the larger the volume of the die-casting mold required, which increases the cost. Utility Model Content

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

[0004] The technical solution adopted by the present invention to solve the above technical problems is: to propose a die-casting mold, comprising:

[0005] Fixed mold assembly;

[0010] A core pulling rod, which is arranged on the slider and is used to form a hole on the workpiece;

[0012] When the inclined guide pillar is separated from the slider, the driving member drives the slider to move so as to drive the core pulling rod to move out of the hole on the workpiece.

[0013] In the above-mentioned die-casting mold, the slider is provided with a sliding hole, and the inclined guide column is movably inserted into the sliding hole.

[0014] In the above-mentioned die-casting mold, the core-pulling rod is provided with a draft angle, and the draft angle facilitates the separation of the core-pulling rod from the hole.

[0016] In the above-mentioned die-casting mold, the output end of the driving member is provided with a first abutting surface and a second abutting surface;

[0017] When the inclined guide post is separated from the slider, the second abutting surface abuts against the outer end surface of the slider;

[0018] When the driving member drives the slider, the first abutting surface abuts against the side wall of the groove.

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figures 1 to 6 As shown, a die-casting mold of the utility model includes:

[0031] Fixed mold assembly 1; movable mold assembly 2, movable mold assembly 2 and fixed mold assembly 1 are movably abutted against each other; driving member 3, driving member 3 is arranged on movable mold assembly 2; slider 4, slider 4 is movably arranged on movable mold assembly 2, and slider 4 is movably connected to the output end of driving member 3; inclined guide column 5, inclined guide column 5 is arranged on fixed mold assembly 1, and inclined guide column 5 is movably inserted on slider 4; core pulling rod 6, core pulling rod 6 is arranged on slider 4, and is used to form holes on the workpiece.

[0032] During operation, the die-casting mold is connected to the die-casting machine, the fixed mold assembly 1 is connected to the fixed part of the die-casting machine, and the movable mold assembly 2 is connected to the movable part of the die-casting machine. The movable mold assembly 2 is driven by the movable part of the die-casting machine to open or close the die-casting mold. When the movable mold assembly 2 and the fixed mold assembly 1 open the mold, the movable mold assembly 2 drives the slider 4 to move in the vertical direction. At the same time, the inclined guide column 5 pushes the slider 4 to move in the horizontal direction, causing the slider 4 to move in the oblique direction. The slider 4 then drives the core pulling rod 6 to move, ultimately achieving the separation of the core pulling rod 6 from the hole position, overcoming the clamping force between the two. After the inclined guide column 5 is separated from the slider 4, the driving member 3 further drives the slider 4 to move, causing the slider 4 to drive the core pulling rod 6 to completely move out of the hole position.

[0033] The slider 4 of this embodiment is provided with a sliding hole 410, and the inclined guide post 5 is movably inserted into the sliding hole 410. When the movable mold assembly 2 and the fixed mold assembly 1 are opened, the movable mold assembly 2 drives the slider 4 to move in the vertical direction. At the same time, the inclined guide post 5 applies a thrust to the sidewall of the sliding hole 410, pushing the slider 4 in the horizontal direction, causing the slider 4 to move in the diagonal direction. The slider 4 then drives the core pulling rod 6 to move, ultimately separating the core pulling rod 6 from the hole, overcoming the clamping force between the two.

[0034] The core pulling rod 6 of this solution is provided with a draft angle, which facilitates the separation of the core pulling rod 6 from the hole. The movable mold assembly 2 and the fixed mold assembly 1 are separated, and the inclined guide column 5 pushes the slider 4 to move, and the slider 4 then drives the core pulling rod 6 to move, finally realizing the separation of the core pulling rod 6 from the hole and overcoming the clamping force between the two. Since the core pulling rod 6 is designed with a draft angle, after the core pulling rod 6 is separated from the hole, there is no longer a clamping force between the two. Therefore, when the driving member 3 drives the slider 4, it only needs to overcome the friction between the slider 4 and the movable mold assembly 2, which makes the tonnage and volume of the driving member 3 required for the mold smaller, thereby reducing the specific volume of the die-casting mold and reducing the overall cost.

[0035] In this embodiment, the slider 4 is provided with a groove 420, and the output end of the driver 3 is movably mounted on the groove 420. The output end of the driver 3 is provided with a first abutment surface 310 and a second abutment surface 320. The inclined guide post 5 pushes the slider 4 until the second abutment surface 320 abuts the outer end face of the slider 4, at which point the inclined guide post 5 separates from the slider 4. The driver 3 then drives its output end along the groove 420 until the first abutment surface 310 abuts the sidewall of the groove 420. The driver 3 then continues to drive the slider 4, which then removes the core puller 6 from the hole in the workpiece.

[0036] In this embodiment, the driving member 3 is configured as a cylinder 330. After the inclined guide post 5 separates from the slider 4, the cylinder 330 drives its output end to move on the groove 420 until the first abutment surface 310 abuts against the sidewall of the groove 420. Subsequently, the cylinder 330 continues to drive the slider 4, which then drives the core puller 6 out of the hole in the workpiece. The cylinder 330 can precisely control the movement of the slider 4 and make its movement more stable.

[0037] The slider 4 of this embodiment includes a first sliding portion 430 and a second sliding portion 440. The second sliding portion 440 is detachably connected to the first sliding portion 430. The first sliding portion 430 is connected to the mounting bracket of the core-pulling rod 6, and the second sliding portion 440 abuts against one end of the core-pulling rod 6. Because the first sliding portion 430 is connected to the core-pulling rod 6 via the mounting bracket, when the inclined guide post 5 pushes the slider 4 to move, the slider 4 also moves the core-pulling rod 6. At this time, the force exerted by the first sliding portion 430 on the core-pulling rod 6 is greater than the clamping force between the core-pulling rod 6 and the hole, allowing the core-pulling rod 6 to be smoothly separated from the hole.

[0038] By setting the mold opening of the movable mold assembly 2 and the fixed mold assembly 1, the inclined guide column 5 pushes the slider 4 to move, and the slider 4 then drives the core pulling rod 6 to move, finally realizing the separation of the core pulling rod 6 from the hole position, overcoming the clamping force between the two. When the inclined guide column 5 is separated from the slider 4, the driving member 3 further drives the slider 4 to move, so that the slider 4 drives the core pulling rod 6 to completely move out of the hole position. This design can reduce the tonnage and volume of the required driving member 3, thereby reducing the specific volume of the die-casting mold to reduce costs.
