Description

Technical Field

[0001] The utility model relates to the technical field of die-casting technology, in particular to a die-casting die with a compacting structure. Background Art

[0002] In a die-casting mold, there are usually three main components: a fixed die assembly, a movable die assembly, and a slider assembly. These components work together to ensure that the die-casting can be accurately formed according to the design requirements. During the mold closing process, the movable die assembly and the fixed die assembly are tightly closed, and the slider is movably connected to the fixed die assembly to form the lateral features of the product, such as holes or flanges; when the mold completes die-casting and is ready to open the mold, the movable die assembly is separated from the fixed die assembly. In this process, if the slider is small in size, the contact area between it and the fixed die assembly may also be relatively small, resulting in a strong bonding force between the slider and the fixed die assembly. Therefore, when the mold is opened, the slider may be driven by the fixed die assembly due to this strong bonding force, resulting in a warping phenomenon relative to the movable die assembly. The occurrence of this situation will cause the connection between the slider and other related components on the movable die assembly to bear additional stress, thereby increasing the risk of deformation of these connection parts. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a die-casting mold with a pressing structure 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 with a compacting structure, comprising:

[0005] Fixed mold assembly;

[0006] A movable mold assembly, which movably abuts against the fixed mold assembly;

[0007] A slider assembly is provided on the movable mold assembly, the slider assembly having a movable slider, the slider being movable and engaging with the fixed mold assembly due to the abutment between the movable mold assembly and the fixed mold assembly, so as to form lateral features of the product;

[0008] A clamping assembly is arranged on the fixed mold assembly, and the clamping assembly has a movably arranged push rod, and the push rod has an initial position and a maximum extension position on the fixed mold assembly. The push rod can be located in the initial position due to the abutment between the fixed mold assembly and the movable mold assembly, and is used to abut against the slider, and is switched to the maximum extension position due to the separation of the movable mold assembly from the fixed mold assembly, and is used to push the slider to abut against the movable mold assembly.

[0009] In the above-mentioned die-casting mold with a clamping structure, a first cavity block is provided on the fixed mold assembly, and a second cavity block is provided on the movable mold assembly. The first cavity block and the second cavity block are movably abutted against each other to form a product cavity.

[0010] In the above-mentioned die-casting mold with a clamping structure, a clamping groove is provided on the first cavity block, one end of the push rod is movably inserted into the clamping groove, and the slider can be movably clamped in the clamping groove due to the abutment between the fixed mold assembly and the movable mold assembly.

[0011] In the above-mentioned die-casting mold with a clamping structure, the clamping assembly also includes an elastic member, which is arranged in the fixed mold assembly, one end of the elastic member is pressed against the fixed mold assembly, and the other end is pressed against one end of the push rod. The elastic member can be compressed and elastically deformed because the push rod is in an initial position, and the elastic deformation is restored because the movable mold assembly is separated from the fixed mold assembly, so as to push the push rod to switch to the maximum extension position.

[0012] In the above-mentioned die-casting mold with a clamping structure, the slider assembly also includes a slider seat, a guide groove is provided on the movable mold assembly, the bottom end of the slider seat has two protrusions extending outward, the protrusions are movably inserted in the guide groove, and the slider seat is used to drive the slider to move.

[0013] In the above-mentioned die-casting mold with a clamping structure, a guide column is obliquely provided on the fixed mold assembly, an oblique hole is provided on the slider seat, and the guide column is movably inserted in the oblique hole to drive the slider seat to move.

[0014] In the above-mentioned die-casting mold with a clamping structure, the movable mold assembly is further provided with an avoidance groove, which is located below the guide groove and is used to prevent the guide column from interfering with the movable mold assembly.

[0015] Compared with the prior art, the advantage of the present invention is that, by arranging a clamping assembly on the fixed mold assembly, when the movable mold assembly and the fixed mold assembly are pressed against each other, the push rod in the clamping assembly is in the initial position and pressed against the slider movably connected to the fixed mold assembly; when the movable mold assembly and the fixed mold assembly are separated, the push rod in the clamping assembly switches from the initial position to the maximum extended position, thereby pushing the slider to press against the movable mold assembly. Through the arrangement of the clamping assembly, the slider is effectively avoided from tilting due to the binding force between the fixed mold assembly and the slider during the mold opening process, thereby ensuring that the slider can maintain stable contact with the movable mold assembly during the mold opening. In this way, not only the additional stress at the connection between the slider and other components is reduced, but also the risk of deformation of these connection parts is avoided, thereby improving the precision and production efficiency of the die-casting parts.

DETAILED DESCRIPTION

[0022] 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.

[0023] like Figures 1 to 5 As shown, the utility model is a die-casting mold with a clamping structure, comprising: a fixed mold assembly 1; a movable mold assembly 2, which is movably abutted against the fixed mold assembly 1; a slider assembly 3, which is arranged on the movable mold assembly 2, and the slider assembly 3 has a movably arranged slider 4, and the slider 4 can be movably clamped on the fixed mold assembly 1 due to the abutment between the movable mold assembly 2 and the fixed mold assembly 1, so as to form the lateral features of the product; a clamping assembly 5, which is arranged on the fixed mold assembly 1, and the clamping assembly 5 has a movably arranged push rod 6, and the push rod 6 has an initial position and a maximum extension position on the fixed mold assembly 1, and the push rod 6 can be located in the initial position due to the abutment between the fixed mold assembly 1 and the movable mold assembly 2, and is used to abut against the slider 4, and is switched to the maximum extension position due to the separation of the movable mold assembly 2 from the fixed mold assembly 1, so as to push the slider 4 to abut against the movable mold assembly 2.

[0024] The working process of the die-casting mold in this scheme is as follows: first, the movable mold assembly 2 is abutted against the fixed mold assembly 1, and the slider 4 is movably engaged with the fixed mold assembly 1. At this time, the push rod 6 is in the initial position and abuts against the slider 4. This structure ensures that the slider 4 can stably form the lateral features of the product, such as holes or flanges, in the mold closing state, and the die-casting work begins. After the die-casting of the workpiece is completed, the movable mold assembly 2 is separated from the fixed mold assembly 1, and the slider 4 is disengaged from the fixed mold assembly 1. At the same time, the clamping assembly 5 drives the push rod 6 to switch from the initial position to the maximum extension position, thereby pushing the slider 4 to abut against the movable mold assembly 2, preventing the slider 4 from tilting relative to the movable mold assembly 2 due to the binding force between the fixed mold assembly 1 and the slider 4, thereby avoiding the connection between the slider 4 and other related components on the movable mold assembly 2 from being subjected to additional stress, and also avoiding the risk of deformation of these connection parts; then, the slider 4 is separated from the push rod 6 under the drive of the movable mold assembly 2, and the molded workpiece is ejected from the movable mold assembly 2, and the die-casting work is completed.

[0025] Specifically, the fixed mold assembly 1 is provided with a first cavity block 7, and the movable mold assembly 2 is provided with a second cavity block. The first cavity block 7 and the second cavity block are movably abutted against each other to jointly form a product cavity.

[0026] Furthermore, a snap-fit ​​groove 8 is provided on the first cavity block 7, and one end of the push rod 6 is movably inserted in the snap-fit ​​groove 8. The slider 4 can be movably snap-fitted in the snap-fit ​​groove 8 due to the abutment between the fixed mold assembly 1 and the movable mold assembly 2; when the movable mold assembly 2 abuts against the fixed mold assembly 1, the slider 4 is movably snap-fitted in the snap-fit ​​groove 8. At the same time, the push rod 6 is in the initial position and one end thereof is tightly abutted against the slider 4 in the snap-fit ​​groove 8.

[0027] Specifically, the clamping assembly 5 also includes an elastic member 9, which is arranged in the fixed mold assembly 1. One end of the elastic member 9 is pressed against the fixed mold assembly 1, and the other end is pressed against one end of the push rod 6. The elastic member 9 can be compressed and elastically deformed because the push rod 6 is in the initial position, and the elastic deformation is restored because the movable mold assembly 2 is separated from the fixed mold assembly 1, so as to push the push rod 6 to switch to the maximum extension position.

[0028] When the movable mold assembly 2 is against the fixed mold assembly 1, the slider 4 is movably engaged in the engaging groove 8, and the slider 4 is pressed against one end of the push rod 6. At this time, the elastic member 9 is compressed and elastically deformed; when the movable mold assembly 2 is separated from the fixed mold assembly 1, the slider 4 is disengaged from the engaging groove 8 under the drive of the movable mold assembly 2. However, if the binding force between the engaging groove 8 and the slider 4 is too large, it may cause the slider 4 to tilt relative to the movable mold assembly 2. At the same time as the slider 4 is disengaged from the engaging groove 8, the force that compresses the elastic member 9 to cause elastic deformation disappears, and the elastic member 9 restores the elastic deformation, driving the push rod 6 to switch from the initial position to the maximum extended position. At this time, the push rod 6 pushes the slider 4 to press against the movable mold assembly 2. Since the force of the push rod 6 pushing the slider 4 is greater than the binding force between the engaging groove 8 and the slider 4, the slider 4 will not tilt. The elastic member 9 is preferably a spring.

[0029] In the present embodiment, the driving member can also drive the push rod 6 to convert from the initial position to the maximum extended position. The driving member is arranged in the fixed mold assembly 1. One end of the push rod 6 is connected to the output end of the driving member, and the other end is movably inserted in the clamping groove 8. When the movable mold assembly 2 and the fixed mold assembly 1 are abutted, the push rod 6 is in the initial position and is tightly pressed against the slider 4 movably clamped in the clamping groove 8. When the movable mold assembly 2 and the fixed mold assembly 1 are separated, the driving member is started, driving the push rod 6 to push the slider 4, so as to avoid the slider 4 from tilting relative to the movable mold assembly 2 due to excessive binding force between the slider 4 and the clamping groove 8. The driving member can be an oil cylinder or an air cylinder.

[0030] Specifically, the slider assembly 3 also includes a slider seat 10, and a guide groove 11 is provided on the movable mold assembly 2. The bottom end of the slider seat 10 has two protrusions extending outward, and the protrusions are movably inserted in the guide groove 11. The slider seat 10 is used to drive the slider 4 to move, and the guide groove 11 is used to provide guidance for the movement of the slider seat 10 on the movable mold assembly 2.

[0031] Furthermore, a guide column 12 is obliquely provided on the fixed mold assembly 1, and an oblique hole 13 is provided on the slider seat 10. The guide column 12 is movably inserted into the oblique hole 13 to drive the slider seat 10 to move in the guide groove.

[0032] In the process of the movable mold assembly 2 approaching the fixed mold assembly 1, one end of the guide column 12 is inserted into the inclined hole 13 on the slider seat 10. As the movable mold assembly 2 gradually approaches the fixed mold assembly 1, the guide column 12 moves along the inclined hole 13, thereby driving the slider seat 10 to move in the guide groove. The movement of the slider seat 10 drives the slider 4 to approach the product cavity. This process continues until the movable mold assembly 2 and the fixed mold assembly 1 are completely pressed against each other. At this time, one end of the slider 4 is inserted into the product cavity to form lateral features of the product, such as holes or flanges. When the movable mold assembly 2 is separated from the fixed mold assembly 1, the guide column 12 drives the slider seat 10 to move in the guide groove away from the product cavity as the movable mold assembly 2 moves in the opposite direction. At the same time, the slider 4 is driven by the slider seat 10 to move away from the product cavity, completing the demolding action.

[0033] Furthermore, the movable mold assembly 2 is provided with an avoidance groove 14 , which is located below the guide groove 11 and is used to prevent the guide column 12 from interfering with the movable mold assembly 2 .
