Abstract
Description
A high-pressure constant-temperature mold for forging Technical Field
[0001] This utility model relates to the field of mold equipment technology, specifically a high-pressure constant-temperature mold for forging. Background Technology
[0002] In the mold industry, molds are various molds and tools used to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded.
[0003] The prior art patent document CN218109232U provides a high-pressure constant temperature mold for forgings. A fan blows hot air from the heating chamber into the lower mold through a pipe. A baffle increases the heating time and range of the hot air, and a constant temperature plate helps maintain a constant temperature in the lower mold. The hot air re-enters the heating chamber through the air outlet, which improves heating efficiency and makes full use of residual heat. If the temperature is too high, simply close the heating chamber, turn the valve assembly to block the first air inlet pipe, and the fan will work normally. At this time, the hot air in the lower mold will be pushed by the exhaust pipe to open a gap in the limiting ball, allowing the hot air to be discharged and the cold air to enter, thus accelerating the cooling effect.
[0004] The existing technology described above can heat the lower mold to maintain a constant temperature, but when cold air is discharged, the air inside the lower mold cannot be quickly exchanged with the outside air due to the obstruction of the internal partition of the lower mold, resulting in low cooling efficiency of the lower mold, which cannot meet people's needs. Therefore, we need a high-pressure constant temperature mold for forging. Summary of the Invention
[0005] The purpose of this invention is to provide a high-pressure constant-temperature mold for forgings, in order to solve the problem mentioned in the background art that the air inside the lower mold cannot be quickly exchanged with the outside air, resulting in low cooling efficiency of the lower mold.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-pressure constant temperature mold for forging, including a base, a lower mold fixedly connected to the top of the base, and an upper mold provided on the top of the lower mold, an inner cavity opened inside the lower mold, a heating component provided on the outer wall of the base, and a cooling component provided on the outer wall of the base.
[0007] The heating assembly includes a mounting shell, and a heater is provided on the inner wall of the mounting shell. A first fan is installed on the inner wall of the mounting shell, and an exhaust pipe is fixedly connected to the outer wall of the mounting shell. A first electrically controlled valve is provided at one end of the exhaust pipe, and an air supply pipe is fixedly connected to the outer wall of the mounting shell. A second electrically controlled valve is provided at one end of the air supply pipe.
[0008] The cooling assembly includes a fan housing, and a second fan is installed on the inner wall of the fan housing. A filter screen is detachably connected to the outer wall of the fan housing, and a fixing bolt is provided on the outer wall of the filter screen. A fixing pipe is fixedly connected to the outer wall of the fan housing, and a third electrically controlled valve is provided at one end of the fixing pipe. An exhaust pipe is fixedly connected to the outer wall of the lower mold, and a fourth electrically controlled valve is provided at one end of the exhaust pipe.
[0009] Preferably, the inner wall shape and size of the mounting shell match the outer wall shape and size of the first fan, and the inner wall of the mounting shell fits snugly against the outer wall of the first fan.
[0010] Preferably, the suction pipe is fixed to the delivery pipe by means of a mounting shell, and the mounting shell is disposed between the suction pipe and the delivery pipe.
[0011] Preferably, the inner wall shape and size of the fan housing match the outer wall shape and size of the second fan, and the inner wall of the fan housing fits into the outer wall of the second fan.

[0014] Preferably, one end of the air supply pipe extends into the lower mold for connection.
[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0016] First, this utility model includes a fan housing, a second fan, a filter screen, fixing bolts, a fixing pipe, a third electrically controlled valve, an exhaust pipe, and a fourth electrically controlled valve. When the first and second electrically controlled valves are closed, the second fan operates to draw in outside air. The filter screen filters and blocks impurities in the air. The second fan blows air into the inner cavity of the lower mold, and the air in the inner cavity is discharged from the exhaust pipe. This accelerates the exchange speed between the air inside the lower mold and the outside air, thereby improving the cooling efficiency of the lower mold and meeting the need for rapid cooling during the production process.
[0017] Secondly, this utility model is equipped with an installation shell, a heater, a first fan, an exhaust pipe, a first electrically controlled valve, an air supply pipe, and a second electrically controlled valve. When the heater and the first fan are working, the first fan blows air to remove the heat generated by the heater, forming hot air. The hot air enters the inner cavity of the lower mold through the air supply pipe, and the air is drawn out through the exhaust pipe to circulate it. During this circulation process, the hot air can continuously and efficiently provide heat to the lower mold, avoiding local overheating or overcooling, and thus accurately maintaining the lower mold at the set constant temperature state.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] As shown in Figures 1-4, a high-pressure constant-temperature mold for forging includes a base 1, a lower mold 2 fixedly connected to the top of the base 1, and an upper mold 3 disposed on the top of the lower mold 2. The lower mold 2 has an inner cavity 4. A heating assembly 5 and a cooling assembly 6 are disposed on the outer wall of the base 1. The heating assembly 5 includes a mounting shell 501, a heater 502 disposed on the inner wall of the mounting shell 501, a first fan 503 mounted on the inner wall of the mounting shell 501, and an exhaust pipe 504 fixedly connected to the outer wall of the mounting shell 501. A first electrically controlled valve 505 is disposed at one end of the exhaust pipe 504. An air supply pipe 506 is fixedly connected to the outer wall of the cooling assembly 6, and a second electrically controlled valve 507 is provided at one end of the air supply pipe 506. The cooling assembly 6 includes a fan housing 601, and a second fan 602 is installed on the inner wall of the fan housing 601. A filter screen 603 is detachably connected to the outer wall of the fan housing 601, and a fixing bolt 604 is provided on the outer wall of the filter screen 603. A fixing pipe 605 is fixedly connected to the outer wall of the fan housing 601, and a third electrically controlled valve 606 is provided at one end of the fixing pipe 605. An exhaust pipe 607 is fixedly connected to the outer wall of the lower mold 2, and a fourth electrically controlled valve 608 is provided at one end of the exhaust pipe 607.
[0025] Through the above technical solution, by closing the first electrically controlled valve 505 and the second electrically controlled valve 507, the second fan 602 operates to draw in outside air. The filter screen 603 filters and blocks impurities in the air. The second fan 602 blows air into the inner cavity 4 of the lower mold 2, and the air in the inner cavity 4 is discharged from the exhaust pipe 607, which accelerates the exchange speed between the air in the inner cavity 4 of the lower mold 2 and the outside air, thereby improving the cooling efficiency of the lower mold 2 and meeting the need for rapid cooling in the production process. By operating the heater 502 and the first fan 503, the first fan 503 blows away the heat generated by the heater 502 to form hot air. The hot air enters the inner cavity 4 of the lower mold 2 through the air supply pipe 506, and is drawn out and circulated through the air extraction pipe 504. In this circulation process, the hot air can continuously and efficiently provide heat to the lower mold 2, avoiding local overheating or overcooling, and thus accurately maintaining the lower mold 2 at the set constant temperature state.
[0026] Specifically, the inner wall shape and size of the mounting shell 501 match the outer wall shape and size of the first fan 503, and the inner wall of the mounting shell 501 fits into the outer wall of the first fan 503.
[0027] The above technical solution enhances the connection between the mounting shell 501 and the first fan 503, facilitating the installation of the first fan 503 within the mounting shell 501. The mounting shell 501 consists of a shell body and a shell cover, making installation convenient. A controller is installed on the outer wall of the mounting shell 501, and a temperature sensor and a pressure sensor are installed in the inner cavity 4 of the lower mold 2. When the pressure sensor detects that the pressure in the inner cavity 4 is close to or exceeds a preset safety threshold, the controller operates to reduce the rotational speed of the first fan 503, thereby reducing the amount of air entering and exiting per unit time. The fourth electrically controlled valve 608 is opened to allow some gas to be discharged, effectively relieving the pressure in the inner cavity 4 and ensuring that the entire heating process is carried out within a safe and stable pressure range. The mounting shell 501 is fixed to the base 1, and the fan shell 601 is fixed to the base 1.
[0028] Specifically, the suction pipe 504 is fixed to the air supply pipe 506 by means of the mounting shell 501, and the mounting shell 501 is located between the suction pipe 504 and the air supply pipe 506.
[0029] The above technical solution enhances the connection between the extraction pipe 504, the mounting housing 501, and the air supply pipe 506, facilitating air circulation between the extraction pipe 504 and the mounting housing 501 and the air supply pipe 506.
[0030] Specifically, the inner wall shape and size of the fan housing 601 match the outer wall shape and size of the second fan 602, and the inner wall of the fan housing 601 fits into the outer wall of the second fan 602.
[0031] The above technical solution enhances the connection between the fan housing 601 and the second fan 602, making it easier to install the second fan 602 inside the fan housing 601.
[0032] Specifically, the fan housing 601 is fixed to the filter screen 603 by fixing bolts 604, and one end of the fixing bolts 604 is threaded through the filter screen 603 and extends into the fan housing 601 for connection.
[0033] Through the above technical solution, there are multiple fixing bolts 604. By using multiple fixing bolts 604, the filter screen 603 can be well fixed on the fan housing 601, which is convenient for installation and disassembly. Operators can regularly remove the filter screen 603 for cleaning.
[0034] Specifically, one end of the air extraction pipe 504 extends into the lower mold 2 for connection.
[0035] The above technical solution facilitates the entry of air from the lower mold 2 into the extraction pipe 504.
[0036] Specifically, one end of the air supply pipe 506 extends into the lower mold 2 for connection.
[0037] The above technical solution facilitates the entry of air from the air supply pipe 506 into the lower mold 2.
[0038] In use, first connect the device to an external power supply. When heating the lower mold 2 is required, close the third and fourth electrically controlled valves 606 and 608, and open the first and second electrically controlled valves 505 and 507. Heat is generated by the heater 502, and blown by the first fan 503. The air passes through the heater 502, carrying away the heat to form hot air. The hot air enters the inner cavity 4 of the lower mold 2 through the air supply pipe 506. The first fan 503 then extracts air from the inner cavity 4 of the lower mold 2 through the air extraction pipe 504 for reheating. This air circulation heating allows for rapid temperature rise, reaching the temperature required for mold constant temperature. When heating is needed... When cooling the lower mold 2, the first and second electrically controlled valves 505 and 507 are closed, while the third and fourth electrically controlled valves 606 and 608 are opened. The second fan 602 operates to draw in outside air. The filter screen 603 blocks dust and impurities from the outside air. The second fan 602 draws in clean air and delivers it into the inner cavity 4 of the lower mold 2. The air is discharged from the exhaust pipe 607, which accelerates the exchange rate between the air in the inner cavity 4 of the lower mold 2 and the outside air, thereby improving the cooling efficiency of the lower mold 2 and meeting the need for rapid cooling during the production process. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
