Description

Technical Field

[0001] This utility model relates to the field of die casting mold demolding technology, and in particular to a die casting mold with a butt-joint buffer structure. Background Technology

[0002] Die casting molds are tools used to cast metal parts, primarily for completing the die casting process on specialized die casting and forging machines. The basic die casting process includes: injecting molten metal into the cavity of a mold at low or high speed. The mold has movable cavity surfaces. As the molten metal cools, pressure is applied to eliminate shrinkage cavities and porosity defects in the blank, allowing the internal structure of the blank to achieve a forged, fragmented grain structure, ultimately significantly improving the overall mechanical properties of the blank.

[0003] Controlling the surface temperature of the die-casting mold is crucial for producing high-quality die-cast parts. Uneven or inappropriate mold temperatures can lead to dimensional instability in the castings, deformation during ejection, and defects such as thermal stress, sticking, surface depressions, shrinkage cavities, and hot bubbles. Significant mold temperature variations can also affect variables in the production cycle, such as filling time, cooling time, and coating time, to varying degrees.

[0004] During die casting, the mold is subjected to a large force when it is joined together, which makes the spring used for cushioning prone to deformation after multiple die castings. The deformed spring is difficult to remove from the cushioning groove for replacement, which causes inconvenience to subsequent die casting. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a die-casting mold with a docking buffer structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A die-casting mold with a docking buffer structure includes a mounting platform, wherein the die-casting mold is disposed at the top center of the mounting platform, and guide columns are disposed around the top of the mounting platform.

[0008] The die-casting mold has a buffer groove around its top, and a mounting base is installed inside the buffer groove. A limit groove is horizontally opened on the outer side of the mounting base, and a connecting shaft is inserted through the limit groove. A rotating shaft is fitted on one side of the connecting shaft that extends out of the limit groove, and a limit block is provided on one side of the rotating shaft.

[0009] The buffer groove has an internal plate, and the internal plate has a bearing, which is rotatably connected to the connecting shaft.

[0010] In addition, a preferred structure is that the top of the guide column is provided with a top plate, and the bottom of the top plate is provided with a die-casting module.

[0011] In addition, a preferred structure is that pressure blocks are provided on both sides of the die-casting module, and a locking block is provided at the bottom of the pressure blocks, and the die-casting module is located directly above the die-casting mold on the top of the mounting platform.

[0012] Furthermore, in a preferred configuration, the die-casting mold has a die-casting groove in the middle, a die-casting port is provided in the middle of the die-casting groove, a buffer spring is provided on the top of the mounting base, a placement plate is provided on the top of the buffer spring, the pressure block and the buffer groove are adapted to each other, and the diameter of the clamping block is larger than the diameter of the buffer spring.

[0013] Furthermore, in a preferred configuration, the shape and size of the limiting block are consistent with the limiting groove, and the limiting block is in a vertical position when locked.

[0014] In addition, a preferred structure is that one side of the limiting block is connected to the connecting shaft, and a magnetic block is provided at the end of the connecting shaft.

[0015] The beneficial effects of this utility model are as follows: Firstly, the buffer spring set on the die-casting mold can provide a certain buffer for the die-casting forging during die-casting. Furthermore, the rotation of the upper limit block on the side of the mounting seat set inside the buffer groove allows the mounting seat to be quickly disassembled, and the buffer spring can be quickly replaced after damage.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 A die-casting mold with a docking buffer structure includes a mounting platform 1, a die-casting mold 2 is provided at the top center of the mounting platform 1, and guide columns 6 are provided around the top of the mounting platform 1.

[0026] The top of the die-casting mold 2 is provided with a buffer groove 23 around the top, and a mounting base 24 is installed inside the buffer groove 23. A limiting groove 26 is horizontally provided on the outer side of the mounting base 24, and a connecting shaft 2703 is provided through the limiting groove 26. A rotating shaft 2701 is sleeved on one side of the connecting shaft 2703 that extends out of the limiting groove 26, and a limiting block 27 is provided on one side of the rotating shaft 2701.

[0027] The buffer groove 23 has an internal plate 5, and the internal plate 5 has a bearing 51, which is rotatably connected to the connecting shaft 2703.

[0028] The top of the guide column 6 is provided with a top plate 3, and the bottom of the top plate 3 is provided with a die-casting module 4.

[0029] In addition, pressure blocks 41 are provided on both sides of the die-casting module 4, and a locking block is provided at the bottom of the pressure blocks 41. The die-casting module 4 is located directly above the die-casting mold 2 on the top of the mounting platform 1.

[0030] Meanwhile, a die-casting groove 21 is opened in the middle of the die-casting mold 2, and a die-casting port 22 is opened in the middle of the die-casting groove 21. A buffer spring 25 is provided on the top of the mounting base 24, and a placement plate is provided on the top of the buffer spring 25. The pressure block 41 and the buffer groove 23 are adapted to each other, and the diameter of the clamping block is larger than the diameter of the buffer spring 25.

[0031] Furthermore, the shape and size of the limiting block 27 are consistent with the limiting groove 26, and the limiting block 27 is in a vertical state when locked.

[0032] Furthermore, one side of the limiting block 27 is connected to the connecting shaft 2703, and a magnetic block 2702 is provided at the end of the connecting shaft 2703.

[0033] In this embodiment, if the extrusion pressure of the die-casting module 4 on the die-casting equipment is too large, the buffer spring 25 used for buffering may get stuck in the buffer groove 23 opened on the die-casting mold 2, making it difficult to remove the buffer spring 25 after it has been squeezed and deformed from the die-casting mold 2, and making it difficult to perform the next die-casting process when it is stuck inside the die-casting mold 2 for a long time.

[0034] At this point, using an external wrench, the limiting block 27 on one side of the mounting base 24 inside the buffer groove 23 drives the rotating shaft 2701 to rotate to a horizontal state, so that the limiting block 27 coincides with the limiting groove 26, and the magnetic block 2702 at the end of the connecting shaft 2703 at the end of the limiting block 27 magnetically attracts the built-in plate 5. At this point, the mounting base 24 can be removed along the direction of the limiting groove 26, and the mounting base 24 and the buffer spring 25 connected to its top can be removed. Then, the new and compatible mounting base 24 and buffer spring 25 are placed in the same way as described above. Then, the limiting block 27 is placed horizontally in the limiting groove 26, and then the limiting sleeve 27 is rotated to a vertical state, so that the mounting base 24 is fixed again, making it easy to disassemble and replace the buffer spring 25 at the top of the mounting base 24.

[0035] In this utility model, the buffer spring 25 provided on the die-casting mold 2 can firstly provide a certain buffer to the die-cast forging during the die-casting process. Then, by utilizing the rotation of the upper limit block 27 on the side of the mounting seat 24 provided inside the buffer groove 23, the mounting seat 24 can be quickly disassembled, and the buffer spring 25 can be quickly replaced after being damaged.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
