Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor packaging, in particular to a cemented carbide type die head structure. Background Technique

[0002] A typical cemented carbide type die head structure includes a die head body, which is made of cemented carbide material. The head of the die head body usually includes a central pattern and a peripheral die wall. There are circumferential grooves on four sides of the central pattern, and an external ring groove is arranged between the circumferential grooves and the peripheral die wall. In order to improve the service life of the die head and the uniformity of the die soldering tin distribution and thickness, a layer of nano-diamond coating may be provided on the surface of these structures.

[0003] However, the existing technology generally uses an integrated die head. When the bottom of the die head is damaged, the entire die head needs to be replaced, which is actually a waste of resources. Because except for the damaged part, other parts of the die head may still be in good condition. The waste of resources not only increases the production cost of the enterprise, but also does not conform to the concept of sustainable development.

[0004] Therefore, it is necessary to provide a new cemented carbide type die head structure to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a cemented carbide type die head structure.

[0006] The cemented carbide type die head structure provided by the utility model includes: a die module, four insertion posts are fixedly connected to the top of the die module, a groove is opened at the center of the top of the die module, through holes are opened on both side walls of the groove, a connecting column passes through the through holes, a connecting block is sleeved at the position of the connecting column in the groove, a connecting seat is fixedly connected to the top surface of the connecting block, and four slots adapted to the insertion posts are opened on the bottom surface of the connecting seat.

[0007] Preferably, both sides of the connecting column extend out of the die module.

[0008] Preferably, external threads are opened at both ends of the connecting column where it extends out of the die module, and mounting blocks are threadedly connected to the external threads.

[0009] Preferably, the bottom edge of the connecting block is smoothly arranged.

[0010] Preferably, a connecting rod is fixedly connected to the top surface of the connecting seat.

[0011] Preferably, the connecting rod is of a hexagonal prism structure.

[0012] Compared with the related technology, the cemented carbide type die head structure provided by the utility model has the following beneficial effects:

[0013] The utility model provides a cemented carbide type die head structure. The die head is a split structure, and the part in contact with the material at the bottom and the part for installing instruments at the top are two separate units. When in use, the two are spliced together. The design of the four insertion posts fixedly connected to the top of the die block and the four slots on the bottom surface of the connecting seat ensures a stable connection between the die block and the connecting seat. This design can effectively prevent displacement or loosening during use and ensure the stability of the overall structure. The matching design of the insertion posts and the slots makes the assembly process simple and fast, without the need for complex tools or techniques. At the same time, this design also makes subsequent maintenance and replacement work more convenient. Through reasonable structural design and material selection, the die block and its related components can withstand a certain amount of pressure and load, which ensures the stability and safety of the equipment under normal working conditions. The design of the groove at the center of the top of the die block and the connecting column not only improves the stability of the structure but also adds a certain degree of aesthetics to the equipment. This design makes the equipment look neater and more generous in appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following further describes the utility model in conjunction with the drawings and embodiments.

[0020] Please refer to Figures 1-4 , wherein, Figure 1 is the overall structural schematic diagram of the cemented carbide type die head structure provided by the utility model; Figure 2 is the split structural schematic diagram of the cemented carbide type die head structure provided by the utility model; Figure 3 is the overall structural schematic diagram of the die head area provided by the utility model; Figure 4 is the overall structural schematic diagram of the connecting column provided by the utility model.

[0021] In the specific implementation process, Figures 1-4 As shown, a carbide die head structure includes a die block 1, four plug posts 2 are fixedly connected to the top of the die block 1, a groove 3 is provided at the center of the top of the die block 1, through holes 4 are provided on both side walls of the groove 3, connecting posts 5 are passed through the through holes 4, the connecting posts 5 are located at the groove 3 and sleeved with a connecting block 6, a connecting seat 7 is fixedly connected to the top surface of the connecting block 6, four slots 8 adapted to the plug posts 2 are provided on the bottom surface of the connecting seat 7, the four plug posts 2 on the top of the die block 1 are adapted to the four slots 8 on the bottom surface of the connecting seat 7, and this design ensures that the connecting seat 7 and the die are in good contact with each other. To improve the stability between the blocks 1 and prevent dislocation or looseness when subjected to force, the connecting column 5 extends out of the pressing module 1 on both sides, and external threads 9 are provided at the ends of the connecting column 5 extending out of the pressing module 1. The external threads 9 are threadedly connected with mounting blocks. The mounting blocks can be nuts or other fasteners to fix the position of the connecting column 5, which increases the stability of the structure. At the same time, compared with direct connection through threaded columns, the smooth connecting column 5 can provide a smoother contact surface for the pressure during the die-casting process, ensuring that the pressure can be transmitted more evenly during the die-casting process. Compared with the threaded column, the smooth connecting column 5 does not have the unevenness of the thread, thereby reducing the pressure concentration caused by the uneven contact surface. When the threaded part of the threaded column is subjected to pressure, stress concentration is prone to occur, resulting in material fatigue or even fracture in this area. The smooth connecting column 5 does not have such structural characteristics, so it can significantly reduce the risk of stress concentration and improve the durability and reliability of the connecting parts. The bottom edge of the connecting block 6 is set to be smooth. The smooth edge reduces the friction and collision with the pressing module 1, reduces the damage to the connecting block 6 and the pressing module 1 caused by extrusion during the film pressing process, and extends the service life of the connecting block and the pressing module 1. The top surface of the connecting seat 7 is fixedly connected to a connecting rod 10, and the connecting rod 10 is a hexagonal prism structure. The connecting rod 10 with a hexagonal prism structure is convenient to operate and fix with tools such as wrenches and screwdrivers, thereby improving work efficiency. The hexagonal prism structure has higher stability than the cylindrical structure and is not prone to rotation or shaking when subjected to force.

[0022] The working principle provided by the utility model is as follows: when the split die head is installed, the plug post 2 on the top of the pressing module 1 is inserted into the groove 3 opened on the bottom surface of the connecting seat 7. At this time, the through hole 4 on the side wall of the pressing module 1 and the axis of the through hole 4 on the connecting block 6 are all in a straight line. The connecting column 5 is inserted into the through hole 4 until the external threads 9 opened on both sides are exposed to the outside of the pressing module 1, and nuts are threadedly connected at the two external threads 9 of the connecting column 5 for fixing.

[0023] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0024] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
