DETAILED DESCRIPTION

[0022] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0023] As shown in Figures 1 to 5 The present application discloses a die-casting die with a material head removing function in the mold, which comprises a fixed die assembly 1, a movable plate 2 movably arranged on the fixed die assembly 1 and having an abutting position and a separation position thereon, the movable plate 2 can be in the abutting position when the die-casting die is closed and in the separation position when the die-casting die is opened, a movable die assembly 3 movably abutting with the movable plate 2 for forming a product cavity, and a material channel, the movable plate 2 and the fixed die assembly 1 abut to form the material channel, the material channel has a feeding end 4 communicating with the product cavity, the diameter of the feeding end 4 gradually decreases at a position close to the cavity, and the feeding end 4 has a first part 5 arranged on the fixed die assembly 1 and a second part 6 arranged on the movable plate 2, the first part 5 can be separated from the second part 6 when the movable plate 2 is converted from the abutting position to the separation position, so as to make the material head formed in the feeding end 4 stay in the first part 5 and disconnect with the product formed in the product cavity.

[0024] In this design, when the die-casting mold closes, the movable plate 2 is in the clamping position, and it fits tightly with the fixed mold assembly 1 to form a material channel. Simultaneously, the movable plate 2 and the moving mold assembly 3 also fit tightly together to form the product cavity. Subsequently, the high-temperature molten metal flows into the product cavity through the material channel. Inside the product cavity, the molten metal cools and solidifies, forming the desired casting. After the product is formed, the die-casting mold opens, and the moving mold assembly 3 separates from the fixed mold assembly 1. Due to the bonding force between the movable plate 2 and the product inside the cavity, the movable plate 2 is driven to separate from the fixed mold assembly 1 during the mold opening process, changing from the clamping position to the separated position. The second part 6 then separates from the first part 5 on the fixed mold assembly 1. Since the diameter of the feed end 4 gradually decreases near the cavity, not only does the sprue formed in the feed end 4 remain on the first part 5, but the cross-section at the connection between the sprue and the product is also minimized. Therefore, driven by the movable plate 2, the sprue formed in the feed end 4 is more easily disconnected from the molded product in the cavity. At this point, the sprue has completely detached from the product and can be easily removed between the fixed mold assembly 1 and the movable plate 2 without the need for an additional process to clean the sprue. Through the automated separation and cleaning process, the time and cost of manual intervention are reduced, and production efficiency is improved.

[0025] Specifically, a fixing block 7 is fixed on the fixed mold assembly 1. The fixing block 7 is firmly installed on the fixed mold assembly 1 by welding, bolt connection or other reliable fixing methods. This ensures that the fixing block 7 remains stable under high pressure and high temperature working environment and will not be displaced or loosened. The fixing block 7 and the first part 5 are manufactured by integral molding. This means that the fixing block 7 and the first part 5 are processed as a whole component during the manufacturing process, ensuring a high degree of integration and tight connection between the two. This integral molding design not only improves the strength and durability of the component, but also reduces the error in the assembly process and ensures the accuracy and reliability of the mold.

[0026] In order to connect the movable plate 2 and the fixed mold assembly 1, the movable plate 2 is provided with a sliding groove 8, and the fixed mold assembly 1 is provided with a connecting rod 9, with the end of the connecting rod 9 away from the fixed mold assembly 1 being movably disposed in the sliding groove 8.

[0027] Specifically, the end of the connecting rod 9 furthest from the fixed mold assembly 1 is provided with an undercut structure 10. During the die-casting mold opening process in this scheme, due to the certain bonding force between the movable plate 2 and the product in the cavity, the movable plate 2 is driven to separate from the fixed mold assembly 1 during the mold opening process, changing from the clamping position to the separation position. At this time, the sliding groove 8 moves along the connecting rod 9 until the undercut structure 10 abuts against the inner wall of one end of the sliding groove 8, ensuring that the connecting rod 9 can firmly grasp the movable plate 2 and prevent the movable plate 2 from falling off or shifting during the movement. This mechanism not only ensures the reliable separation of the movable plate 2 from the fixed mold assembly 1, but also ensures that the movable plate 2 can smoothly change from the clamping position to the separation position.

[0028] Furthermore, a feed sleeve 11 is also provided on the fixed mold assembly 1. The feed sleeve 11 is firmly installed on the fixed mold assembly 1 by threaded connection, welding or other reliable fixing methods. This can ensure that the feed sleeve 11 remains stable under high pressure and high temperature working environment and will not be displaced or loosened. One end of the feed sleeve 11 is connected to the external molten metal supply system, and the other end is connected to the end of the material channel away from the product cavity. This design ensures that the molten metal can smoothly enter the material channel from the external supply system through the feed sleeve 11 and finally flow into the product cavity.

[0029] Furthermore, a guide post 12 is provided on the fixed mold assembly 1, and a guide sleeve 13 is provided on the moving mold assembly 3. The guide post 12 is movably inserted into the guide sleeve 13. When the die-casting mold in this solution is closed, the guide sleeve 13 is sleeved on the guide post 12 under the drive of the moving mold assembly 3 and moves along the guide post 12 until the moving mold assembly 3 and the fixed mold assembly 1 are pressed together. During this process, the guide sleeve 13 moves along the guide post 12, providing precise guidance for the movement of the moving mold assembly 3.
