Description

Technical Field

[0001] This utility model relates to the technical field of forging dies, specifically to an isothermal forging die for titanium alloy forgings with a warped thin plate structure. Background Technology

[0002] Isothermal forging dies for titanium alloys are dies specifically designed for isothermal forging processes of titanium alloys. Their core feature is that they heat the die and the titanium alloy billet to the same optimal temperature and forge under isothermal conditions. They are mainly used to process titanium alloy materials to obtain high-precision, high-performance forgings. Some titanium alloy forgings have warped thin plate structures, which require specific dies for production.

[0003] Existing titanium alloy forging molds generally use one-piece molding molds. After the upper and lower molds are closed, the raw material is injected and heated and temperature controlled before production. However, the shapes of forgings are diverse and need to be adjusted according to production requirements. Therefore, there is no standardized universal mold and custom molds are required. In addition, the molds also need to take into account the heating function. If the one-piece mold is damaged, the whole thing needs to be replaced, which is costly. Moreover, the existing molds use single-hole injection during the filling process, which can easily lead to uneven flow, especially in thin plate parts, affecting product quality. Utility Model Content

[0004] This invention provides an isothermal forging die for titanium alloy forgings with a warped thin plate structure, which has the advantages of modular installation and replacement, low die cost, and uniform material injection, thus solving the problems of high cost and uneven flow of raw materials injected into the die cavity of existing one-piece forging dies.

The positioning pins are movably connected to and fit into the positioning grooves.

[0011] As a preferred technical solution of this utility model, the first heating plate is provided with upper and lower layers, and the two layers of the first heating plate are connected in parallel and can be controlled independently.

[0012] As a preferred technical solution of this utility model, the top surface of the thin plate groove is provided with multiple assembly holes, and multiple assembly pins are symmetrically installed at the four corners of the bottom of the thin plate template. The assembly pins are movably connected to and fit into the assembly holes.

The injection tube is perpendicular to the connection port and the main body cavity. The bottom surface with the highest vertical height on one side of the upper mold plate is provided with multiple injection holes arranged at equal intervals. The injection holes are connected to the distribution cavity.

[0016] Compared with the prior art, this utility model provides an isothermal forging die for titanium alloy forgings with a warped thin plate structure, which has the following beneficial effects:

[0017] 1. This utility model separates the titanium alloy forging mold with a thin plate structure into two parts: the main body and the thin plate. The two parts can be independently assembled in a heating mounting base. They can be freely assembled to facilitate the replacement of the bottom mold to produce different titanium alloy forgings.

[0032] The upper mold plate 22 is movably connected to and fits the thin plate cavity 135.

[0033] Please refer to the appendix. Figure 3 , Figure 4 The main template 12 has symmetrical positioning grooves 126 at the four corners of the bottom. Multiple positioning pins 115 are installed on the bottom surface of the main groove 113. The positioning pins 115 are movably connected to and fit the positioning grooves 126.

[0034] Specifically, the positioning pin 115 and the positioning groove 126 can be used to quickly position the template 12 during assembly, thus preventing template offset.

[0035] Furthermore, the first heating plate 114 is provided with upper and lower layers, and the two layers of the first heating plate 114 are connected in parallel and can be controlled independently.

[0036] Specifically, when using the main template 12 with a shallow main mold cavity, only the first heating plate 114 of the higher second layer can be activated to work, avoiding energy waste and saving production costs.

[0037] Please refer to the appendix. Figure 3 , Figure 5 The top surface of the thin plate groove 116 is provided with multiple assembly holes 117, and multiple assembly pins 131 are symmetrically installed at the four corners of the bottom of the thin plate template 13. The assembly pins 131 are movably connected to and fit the assembly holes 117.

[0038] Specifically, the assembly pin 131 and the assembly hole 117 can be used to quickly position the thin plate template 13 during assembly, thus preventing the thin plate template 13 from shifting.

[0039] Furthermore, the upper end of the main template 12 is provided with a sealing groove 125 surrounding the main mold cavity, and the bottom of the thin plate template 13 is equipped with a rectangular closed sealing strip 133. The bottom of the thin plate template 13 is precisely fitted with the top of the main template 12, and the sealing strip 133 is movably connected and cooperates with the sealing groove 125.

[0040] Specifically, the sealing strip 133 and the sealing groove 125 can improve the sealing performance of the connection between the thin plate template 13 and the main template 12, and prevent external air from affecting the bonding between the two.

[0041] Furthermore, the main template 12 is provided with multiple operating slots 123, and an operating ring 124 is installed in the operating slot 123. The thin plate template 13 is provided with symmetrical picking slots 134 on both sides. The main template 12 and the thin plate template 13 are all heat-conducting plates 122 on all four sides.

[0043] Based on the above embodiment 1, please refer to the appendix. Figure 6 , Figure 7 The upper mold plate 22 is fixed to the bottom of the fixed plate 21. An injection pipe 23 is installed at the center of the bottom of the upper mold plate 22. The injection pipe 23 is perpendicular to the connection port 132 and the main body cavity 121. The bottom surface of the upper mold plate 22 with the highest vertical height on one side is provided with multiple injection holes 24 arranged at equal intervals. The injection holes 24 are connected to the distribution cavity 25 connected to the external material supply equipment.

[0044] In this embodiment, the injection tube 23 directly injects material into the main body cavity 121, and the injection hole 24 injects material from the highest point of the thin plate mold cavity. After the main body mold cavity is filled, multiple injection holes 24 arranged in a row inject material evenly into the thin plate mold cavity, so that the raw material flows evenly in the thin plate mold cavity and avoids local thin gaps in the thin plate mold cavity.

[0045] The working principle and usage process of this utility model: The fixed plate 21 is connected to the external lifting drive device. After the fixed plate 21 drives the upper mold plate 22 to move downward and close with the thin plate template 13, the injection pipe 23 and the injection hole 24 feed the material into the main mold cavity and the thin plate mold cavity. After the feeding is completed, the first heating plate 114 and the second heating plate 118 are activated, and the heat is transferred through the heat conduction plate 122 of the thin plate template 13 and the main template 12 to the raw material in the main mold cavity and the thin plate mold cavity for heating and assisting in the forming of the forging.

[0046] When it is necessary to replace the template with another shape or size or when the template is damaged, the thin plate template 13 is lifted upwards from the thin plate groove 116 by taking out the groove 134. Then, the fingers are inserted into the operating groove 123 to hook the operating ring 124 and lift the main template 12 upwards from the main plate groove 113. Then, the new main plate template 12 is placed into the main plate groove 113, so that the positioning pin 115 in the main plate groove 113 is inserted into the positioning groove 126 at the bottom of the main plate template 12. Then, the new thin plate template 13 is placed in the thin plate groove 116, so that the assembly pin 131 at the bottom of the thin plate template 13 is inserted into the assembly hole 117 in the thin plate groove 116, and the sealing strip 133 at the bottom of the thin plate template 13 is inserted into the sealing groove 125 at the top of the main plate template 12, so that the thin plate template 13 and the main plate template 12 fit tightly together, and the replacement is completed.
