Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a combined metal forging mold structure. Background Technology
[0002] Forging dies are tools that shape blanks into forgings. They are essential and critical process equipment in forging production, used in every stroke of the equipment, and play a crucial role in the process. Modular metal forging dies are multi-functional forging structures achieved through modular design. They consist mainly of multiple detachable components, suitable for different forging stages. They typically include components such as punches, dies, intermediate dies, and ejector pins. The punch and die are connected via the intermediate die, forming a combination of pre-forging and final forging functions. The die contains a forging cavity, which can be switched to a pre-forging cavity or a final forging cavity according to process requirements.
[0003] Chinese patent document CN218395776U discloses a precision forging die for metal parts, including a moving die, a fixed die below the moving die, an outer ring base below the fixed die, a punch mounted at the bottom of the moving die, a slot at the top of the fixed die, a forging placed inside the slot, unloading components symmetrically arranged on both sides of the bottom of the punch, a water storage mounting groove at the center of the top of the outer ring base, a stabilizing frame welded to the bottom of the inner wall of the water storage mounting groove, multiple mounting holes at the bottom of the fixed die, and mounting posts welded to the bottom of the inner wall of the water storage mounting groove at positions opposite to the mounting holes. This patent document uses both air cooling and water cooling to reduce the temperature inside the slot, improving the cooling speed and effect of the die, preventing the forging from sticking to the slot, and allowing for the removal of forgings stuck on the punch without manual removal, thus improving production efficiency.
[0004] The aforementioned patent documents can reduce the temperature inside the punch groove through both air cooling and water cooling during implementation, thereby improving the speed and effect of mold cooling. However, they cannot effectively guarantee the precision of mold forging, resulting in dimensions that do not meet the drawing requirements, affecting the assembly precision and functional realization of the parts.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1As shown, a combined metal forging die structure includes a lower pad 1. A limiting mechanism 2 is symmetrically fixedly connected to the upper left and right sides of the outer surface of the lower pad 1, which can limit the movement of several guiding mechanisms 10. A cavity 3 is fixedly connected to the middle of the upper part of the outer surface of the lower pad 1. A bearing mechanism 4 is fixedly connected to the upper part of the outer surface of the cavity 3, which can bear the load of two buffer mechanisms 5. Buffer mechanisms 5 are symmetrically fixedly connected to the left and right sides inside the bearing mechanism 4, which can buffer the collision force generated by the upper die assembly 6. The upper die assembly 6 is movably connected to the upper side of the bearing mechanism 4, which can cooperate with the cavity 3 to forge metal parts. Positioning mechanisms 7 are fixedly connected to the four corners of the upper die assembly 6, which can lock the position of the upper die assembly 6. An upper pad 8 is fixedly connected to the upper part of the outer surface of the upper die assembly 6. A filling port 9 is fixedly connected to the middle of the upper pad 8. Guide mechanisms 10 are symmetrically fixedly connected to the left and right sides of the lower end of the upper pad 8, which can guide the movement of the upper die assembly 6.
[0024] To achieve the purpose of limiting the movement of several guide mechanisms 10, see [reference] Figure 2 The limiting mechanism 2 includes a fixed base 21, and a limiting sleeve 22 is symmetrically fixedly connected to the upper part of the fixed base 21, which can guide and limit the movement of the guide rod 102.
[0025] To achieve the purpose of supporting the two buffer mechanisms 5, refer to... Figure 2 The supporting mechanism 4 includes a rectangular frame 41. Threaded holes 42 are provided at the four corners of the upper part of the outer surface of the rectangular frame 41, which can accommodate and fasten the corresponding fastening screws 72.
[0026] To buffer the impact force generated by the upper mold assembly 6, please refer to... Figure 3 The buffer mechanism 5 includes a spring sheet 51, with a support plate 52 fixedly connected to the upper end of the outer surface of the spring sheet 51, and the lower end of the outer surface of the spring sheet 51 fixedly connected to the bottom wall of the inner cavity on one side of the rectangular frame 41.
[0027] During the process of inserting the core 61 into the cavity 3, the core 61 is prone to collide with the upper part of the cavity 3 due to the weight of the upper pad 8 and the core 61 itself. At this time, the spring plate 51 can push the support plate 52 upward to move upward, thereby buffering the collision force generated when the core 61 descends and avoiding excessive impact force from damaging the cavity 3 and the core 61.
[0028] To achieve the purpose of forging metal parts in conjunction with cavity 3, refer to Figure 4The upper mold assembly 6 includes a core 61. Limiting plates 62 are symmetrically fixedly connected to the left and right ends of the outer surface of the core 61, which can connect the transmission block 71. The upper end of the outer surface of the core 61 is fixedly connected to the middle of the lower end of the upper pad 8.
[0029] To achieve the purpose of locking the position of the upper mold component 6, refer to... Figure 4 The positioning mechanism 7 includes a transmission block 71, and a fastening screw 72 is threadedly connected to the middle of the inner cavity of the transmission block 71, which can lock the limiting plate 62 on the upper end of the outer surface of the rectangular frame 41. The left end of the outer surface of the transmission block 71 is fixedly connected to the right end of the corresponding outer surface of the limiting plate 62.
[0030] To guide the movement of the upper mold assembly 6, see [reference needed]. Figure 4 The guide mechanism 10 includes a limiting rod 101, and a guide rod 102 is fixedly connected to the lower end of the outer surface of the limiting rod 101. The guide rod 102 is movably connected to the inner cavity of the corresponding limiting sleeve 22.
[0031] When the core 61 is placed on the upper part of the cavity 3, several guide rods 102 move slowly downward along the inner cavity of the corresponding limiting sleeve 22, so that the core 61 can be tightly and accurately locked in the inner cavity of the cavity 3.
[0032] The working principle of this utility model is as follows: When metal forging is required, the core 61 is first slowly inserted into the cavity 3 by holding the upper pad plate 8. During this process, several guide rods 102 slide downward along the inner cavity of the limiting sleeve 22, which is aligned with the guide rod. When the core 61 slides to the lower part of the cavity 3 under its own weight, the upper pad plate 8 is pressed down to make the two limiting plates 62 fully contact the upper surface of the rectangular frame 41. Then, several fastening screws 72 are rotated to lock them into the corresponding threaded holes 42, so that the core 61 can be fully inserted into the cavity 3. Then, a sufficient amount of forging solution is injected into the cavity 3 through the injection port 9. After shaping, the fastening screws 72 are rotated and removed. At this time, the rebound force of the two spring plates 51 will push the corresponding support plate 52 upward, so that the demolding of the core 61 can be completed more easily under the upward pushing force of the two support plates 52.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
