Description

Technical Field

[0001] The utility model relates to the field of die-casting technology, in particular to an integrated die-casting die for new energy vehicles with a removable head in the die. Background Art

[0002] Die casting is a precision casting method mainly used to produce metal parts with complex shapes and high precision requirements. The basic principle of this process is to quickly inject molten metal into a metal mold (also called a die casting mold) under high pressure, and then cool and solidify inside the mold to finally form the desired part shape. The die casting process is widely used in many industries such as automobiles, aviation, and electronics because of its high efficiency and ability to produce parts with complex structures.

[0003] In the die casting process, the sprue (also called "gate" or "overfill") refers to the solidified product of the remaining metal material in the additional channels designed to ensure the smooth flow of molten metal into the mold cavity during the casting process. These channels include the main channel, branch channel and gate in the casting system. After the casting is formed, these additional metal materials usually adhere to the finished casting. In the existing technology, additional mechanical removal, or manual shearing, sawing or grinding is generally used, which not only reduces work efficiency, but also increases production costs.

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figures 1 to 5 As shown, the utility model is an integrated die-casting mold for new energy vehicles with a removable material head in the mold, comprising: a fixed mold component 1, on which a feed sleeve 2, a first template 3 and a second template 4 are arranged, the first template 3 and the second template 4 are movably abutted to form a flow channel, the flow channel has a plurality of flow grooves 5, and the flow grooves 5 are connected to the feed sleeve 2; a movable mold component 6, which abuts against the second template 4 to form a product cavity, and the product cavity is connected to the flow channel; a pushing component 7, which has a pushing member 8 movably arranged in the flow groove 5, the pushing member 8 has an initial position and a working position on the flow groove 5, the pushing member 8 can be in the initial position due to the abutment of the first template 3 and the second template 4, for letting the flow groove 5, and is in the working position due to the separation of the first template 3 and the second template 4, for pushing the material head formed in the flow groove 5; a rejecting component 9, which has a rejecting member 10 movably arranged on the second template 4, for rejecting the material head from the molded casting.

[0029] When the die-casting mold in this scheme is closed, the first template 3 and the second template 4 are pressed against each other to form a flow channel. At the same time, the second template 4 and the movable mold assembly 6 are pressed against each other to form a product cavity. Subsequently, the molten metal flows into the flow channel from the feed sleeve 2 and flows into the product cavity through the flow channel. After the casting in the product cavity is formed, the movable mold assembly 6 moves relative to the first template 3. The second template 4 is driven by the movable mold assembly 6 due to the bonding force between the second template 4 and the molded casting in the cavity, and moves away from the first template 3 synchronously. At this time, the flow channel between the first template 3 and the second template 4 is exposed. At the same time, the push mold assembly 6 is pushed away from the first template 3. The moving component 7 drives the pushing member 8 to be converted from the initial position to the working position, and pushes the material head formed in the flow groove 5 away from the flow groove 5. The setting of the pushing member 8 prevents the material head from being stuck in the flow groove 5 when the first template 3 is separated from the second template 4. Subsequently, the rejecting member 10, driven by the rejecting component 9, rejects the material head on the second template 4 from the casting formed in the product cavity. This method of removing the material head does not require an additional process to clean the material head on the casting. Through the automated separation and cleaning process, the time and cost of manual intervention are reduced, thereby improving production efficiency.

[0030] Furthermore, the pushing member 8 is movably abutted against the second template 4. When the die-casting mold in this scheme is closed, the first template 3 is abutted against the second template 4. At this time, the pushing member 8 is moved to the initial position in the flow groove 5 under the push of the second template 4, ensuring that the flow groove 5 is unobstructed, thereby not affecting the normal flow of the metal solution in the flow groove 5.

[0031] Specifically, the pushing assembly 7 includes: a support frame 11, which is arranged on the first template 3, and the pushing member 8 is connected to the support frame 11; an elastic member 12, which is sleeved on the support frame 11, and one end of the elastic member 12 is against the first template 3, and the other end is against the support frame 11; when the first template 3 is against the second template 4, the pushing member 8 is pushed by the second template 4 to move to the initial position in the flow groove 5, at this time, the support frame 11 is driven by the pushing member 8 to move synchronously, and at the same time, the elastic member 12 is compressed and is in an elastic deformation state and stores potential energy; when the first template 3 is separated from the second template 4, the force pushing the pushing member 8 disappears, and at the same time, the force of compressing the elastic member 12 disappears, and the elastic member 12 recovers from the elastic deformation state, and drives the pushing member 8 to move from the initial position to the working position through the support frame 11. At this time, the material head formed in the flow groove 5 is pushed away from the flow groove 5 by the pushing member 8, thereby avoiding the situation that the molded material head is stuck in the flow groove 5 and cannot be cleaned when the first template 3 is separated from the second template 4. The elastic member 12 is preferably a spring.

[0032] Specifically, the rejection component 9 also includes a driving member 13, which is arranged on one side of the second template 4. The output end of the driving member 13 is provided with a stepped shaft, and the rejection member 10 is provided with a T-shaped slot. The large end of the stepped shaft is connected to the large end of the T-shaped slot. This connection method ensures that the driving member 13 can effectively transmit power to the rejection member 10, so that it can accurately perform the rejection action; when the first template 3 is separated from the second template 4, the molding slug in the flow channel will also be pushed to the second template 4 by the pushing component 7 at the same time, and then the driving member 13 is immediately started, driving the rejection member 10 to apply a thrust to the slug to disconnect it from the molded casting in the cavity. Through this approach, the slug is removed from the molded casting when the mold is opened in the present scheme, and there is no need to add an additional process to clean the slug on the casting, thereby improving the work efficiency of the die-casting work. The driving member 13 is preferably a cylinder.

[0033] In order to provide guidance for the movement of the rejection member 10, a guide portion 14 is provided on the second template 4, and first sliding grooves 15 are provided on both sides of the guide portion 14. Two protrusions extending outward are provided at the bottom of the rejection member 10, and the two protrusions respectively abut against the two first sliding grooves 15. When the driving member 13 drives the rejection member 10 to move, the protrusions move along the first sliding grooves 15, ensuring that the movement trajectory of the rejection member 10 is stable and precise, thereby ensuring that the rejection member 10 can accurately apply thrust to the material head.

[0034] In order to connect the first template 3 with the second template 4, a connecting rod 16 is provided on the first template 3, and a second sliding groove 17 is provided on the connecting rod 16. A connecting block 18 is provided on the second template 4, and the connecting block 18 is slidably set in the second sliding groove 17. The second sliding groove 17 is set along the length direction of the connecting rod 16.

[0035] Furthermore, the connecting block 18 has a first connecting position and a second connecting position in the second sliding groove 17. When the first template 3 and the second template 4 are abutted, the connecting block 18 is located at the first connecting position of the second sliding groove 17 to ensure that the first template 3 and the second template 4 are tightly fitted. When the first template 3 and the second template 4 are separated, the connecting block 18 moves along the second sliding groove 17 to the second connecting position. At this time, the connecting rod 16 drives the second template 4 and the first template 3 to move synchronously through the connecting block 18, so that the second template 4 is separated from the movable mold assembly 6 and the molded casting in the cavity.

[0036] Furthermore, a guide column 19 is provided on the fixed mold assembly 1, and a guide hole is provided on the movable mold assembly 6. The guide column 19 is movably inserted in the guide hole. When the die-casting mold in this scheme is closed, the movable mold assembly 6 approaches the fixed mold assembly 1. During this process, the guide hole gradually approaches and is sleeved on the guide column 19. Subsequently, the guide hole moves along the guide column 19 until the closing process is completed; when the mold in this scheme is opened, the movable mold assembly 6 moves along the guide column 19 through the guide hole in a direction away from the fixed mold assembly 1. The setting of the guide column 19 and the guide hole ensures that the movement trajectory of the movable mold assembly 6 is stable and precise. This design not only reduces the shaking and deviation of the movable mold assembly 6 during the movement, but also improves the closing accuracy and stability of the die-casting mold.

[0037] Furthermore, a through hole 20 is provided on the second template 4, and one end of the guide column 19 away from the movable mold assembly 6 passes through the through hole 20 and is connected to the first template 3. The second template 4 is movably sleeved on the guide column 19 through the through hole 20. When the second template 4 moves relative to the first template 3, the second template 4 moves along the guide column 19 through the through hole 20. In this way, the cooperation between the guide column 19 and the through hole 20 ensures the smooth movement of the second template 4 during the mold closing and opening process, reduces wear, and extends the service life of the mold. At the same time, this guide design also improves the efficiency and reliability of production, and ensures the quality and consistency of the casting.
