Description

Technical Field

[0001] This utility model relates to a forging die, and more particularly to a high-efficiency homogeneous forging die, belonging to the field of mechanical equipment die technology. Background Technology

[0002] In the prior art, such as the utility model with application number 202322046094.3, a new type of automotive crankshaft forging die is disclosed. In order to solve the problem that automatic cleaning of the die cannot be achieved, and that sweeping cleaning cannot completely remove adhesive residues and debris, the first nozzle is set below the forging die body by adjusting the first bellows, and the second nozzle is set above the forging die body by adjusting the second bellows. The air pump is started so that the gas is compressed and passes through the first and second bellows, and then sprays out from the first and second nozzles, thereby blowing away the residues and debris inside the forging die body, and at the same time blowing away the residues and debris inside the slot.

[0003] The above-mentioned applications still have shortcomings:

[0004] During the process of removing dust from the mold surface by compressed gas, the mold will be cooled to a certain extent, resulting in a large temperature gradient between the mold and the casting. This causes thermal stress in the casting, which may cause cracks in the casting.

[0005] To address this issue, a high-efficiency homogeneous forging die was designed. Utility Model Content

[0006] The main objective of this invention is to provide a high-efficiency homogeneous forging die to solve the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A high-efficiency homogeneous forging die includes a lower die and a base located at the bottom of the lower die and fixed in position to the lower die. A preheating mechanism is provided on the outside of the base. The preheating mechanism includes a heating chamber, which is opened on the outside of the base. An air inlet pipe communicating with the inside of the heating chamber is installed on the outside of the base. A heating plate is installed inside the heating chamber.

[0009] A dust removal mechanism is provided on one side of the top of the base. The dust removal mechanism includes a slide plate, which is vertically slidably disposed on the side of the base. A second air vent is opened inside the slide plate, and the bottom end of the second air vent is connected to the interior of the heating chamber. A reset component for controlling the raising and lowering of the slide plate is provided on the side of the base.

[0010] Preferably, a spiral conduit is provided inside the base and outside the heating chamber. The top end of the spiral conduit is connected to the air inlet pipe, and the bottom end of the spiral conduit is connected to the inside of the heating chamber at the position below the slide plate.

[0011] Preferably, the top of the heating chamber is provided with a first exhaust vent, and the first exhaust vent extends to the top of the base.

[0012] Preferably, a sealing gasket is fixed at the bottom end of the slide plate near the air intake pipe, and the diameter of the sealing gasket is larger than the diameter of the connection between the spiral duct and the heating chamber.

[0013] Preferably, the second air outlet is L-shaped, and the top of the second air outlet is inclined towards the inside of the lower mold.

[0014] Preferably, the reset assembly includes a first positioning plate, a second positioning plate, and a reset spring. The first positioning plate is horizontally fixed to the outside of the slide plate, the second positioning plate is parallel to the first positioning plate and fixed to the side of the base, and a reset spring is provided between the second positioning plate and the first positioning plate.

[0015] Preferably, a sliding rod is vertically fixed to the bottom of the first positioning plate, the sliding rod passes through the inside of the return spring and is slidably connected between the second positioning plate and the first positioning plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model has a preheating mechanism consisting of a heating chamber, a heating plate, a spiral conduit, an air inlet pipe, and a first exhaust port inside the base. This mechanism can preheat the mold during the forging process, so that the cooling rate of the casting is more uniform during solidification, reducing the generation of thermal stress, improving the quality of the casting, and reducing the scrap rate.

[0018] 2. This utility model features a sliding plate on the side of the base, with a second air vent on the plate that communicates with the interior of the heating chamber. After forging, hot air can be discharged from the second air vent to clean the interior of the mold without accelerating its cooling. When used in conjunction with a reset assembly consisting of a first positioning plate, a second positioning plate, a sliding rod, and a reset spring, the sliding plate can automatically control its retraction during mold closing to ensure stable forging. Furthermore, after the sliding plate is inserted into the heating chamber, the air inlet of the heating chamber can be blocked with a sealing gasket to stop dust removal, making it more energy-efficient.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a high-efficiency homogeneous forging die, including a lower die 1 and a base 2 located at the bottom of the lower die 1 and fixed in position to the lower die 1. A preheating mechanism 3 is provided on the outside of the base 2. The preheating mechanism 3 includes a heating chamber 301, which is opened on the outside of the inside of the base 2. An air inlet pipe 304 communicating with the inside of the heating chamber 301 is installed on the outside of the base 2. A heating plate 302 is installed inside the heating chamber 301. The use of the heating plate 302 can preheat the die during the forging process to reduce the temperature difference between the die and the casting.

[0034] A dust removal mechanism 4 is provided on one side of the top of the base 2. The dust removal mechanism 4 includes a slide plate 401, which is vertically slidably disposed on the side of the base 2. A second air vent 402 is provided inside the slide plate 401. The bottom end of the second air vent 402 is connected to the inside of the heating chamber 301. A reset component for controlling the lifting and lowering of the slide plate 401 is provided on the side of the base 2. During the dust removal process, the slide plate 401 is lifted by the reset component, and the second air vent 402 is located at the top of the lower mold 1. At this time, the high-pressure gas from the air pump enters the inside of the heating chamber 301 through the air inlet pipe 304, is heated, and is discharged from the second air vent 402 to clean the mold.

[0035] Example 2

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, a spiral conduit 303 is further provided inside the base 2 and outside the heating chamber 301. The top end of the spiral conduit 303 is connected to the air inlet pipe 304, and the bottom end of the spiral conduit 303 is connected to the inside of the heating chamber 301 at the position below the slide plate 401. The use of the spiral conduit 303 can increase the residence time of the outside cold air inside the base 2 to ensure the heating effect of the air.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the top of the heating chamber 301 is further provided with a first exhaust port 305, and the first exhaust port 305 extends to the top of the base 2. After the mold is opened, compressed air enters the heating chamber 301, and hot air is discharged upward through the first exhaust port 305, which can preheat the upper mold.

[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, a sealing gasket 403 is further fixed at the bottom end of the slide plate 401 near the air inlet pipe 304. The diameter of the sealing gasket 403 is larger than the diameter of the connection between the spiral conduit 303 and the heating chamber 301. After the slide plate 401 is moved down by the upper mold into the interior of the heating chamber 301, the sealing gasket 403 will block the opening at the bottom of the spiral conduit 303, thus preventing the release of gas and stopping the dust removal operation, which is more energy-efficient.

[0040] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the second exhaust vent 402 is further L-shaped, and the top of the second exhaust vent 402 is inclined toward the inside of the lower mold 1. The hot air discharged from the second exhaust vent 402 is inclined toward the lower mold 1 to ensure the dust removal effect.

[0041] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the reset assembly further includes a first positioning plate 404, a second positioning plate 405, and a reset spring 407. The first positioning plate 404 is horizontally fixed to the outside of the slide plate 401, and the second positioning plate 405 is parallel to the first positioning plate 404 and fixed to the side of the base 2. A reset spring 407 is provided between the second positioning plate 405 and the first positioning plate 404. When the upper mold is pressed down, it controls the downward movement of the slide plate 401 to squeeze the reset spring 407. When the mold is opened, the reset spring 407 automatically resets and controls the upward movement of the slide plate 401, making it more convenient to use.

[0042] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a sliding rod 406 is vertically fixed to the bottom of the first positioning plate 404. The sliding rod 406 passes through the inside of the return spring 407 and is slidably connected between the second positioning plate 405. The use of the sliding rod 406 can prevent the return spring 407 from deforming outward, thus ensuring the reset effect of the slide plate 401.

[0043] Example 3

[0044] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0045] During use, the lower mold 1 is fixed inside the base 2. The heating plate 302 is kept energized to heat the interior of the heating chamber 301. The lower mold 1 is preheated directly through contact transmission. The air inlet pipe 304 is connected to the air pump to continuously supply gas to the interior of the heating chamber 301. External gas enters the interior of the heating chamber 301 through the spiral conduit 303 for heating. The spiral conduit 303 prolongs the residence time of the external gas inside the base 2, ensuring the heating effect of the gas. After being heated, the gas is discharged upward from the first exhaust port 305 to preheat the upper mold. At the same time, the gas is also discharged from the second exhaust port 402 to clean the lower mold 1. When the mold is closed, the upper mold is pressed down to close the gap with the lower mold 1. At the same time, the sliding plate 401 is pressed into the interior of the heating chamber 301. The sealing gasket 403 seals the port of the spiral conduit 303 to stop the dust removal operation. After the mold is opened, the return spring 407 automatically resets the sliding plate 401, allowing the gas to be discharged, and simultaneously performing dust removal and preheating operations.

[0046] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
