Description

Technical Field

[0001] This utility model relates to the field of vacuum pumping technology, and in particular to a vacuum pump for heat treatment and quenching of metal molds. Background Technology

[0002] Currently, when evacuating air during the hot quenching of metal molds, the air pump is usually directly connected to the vacuum furnace. Furthermore, the pump does not have the function of filtering the gas during evacuation. Since the quenching process generates a large amount of dust, when the vacuum pump is extracting gas, a large amount of dust will enter the vacuum pump. This not only easily causes blockage of the vacuum pump's pipeline, but also the direct discharge of dust-laden exhaust gas will pollute the environment, which is not conducive to environmental protection and emission reduction.

[0003] The prior art CN219409804U discloses a vacuum pumping device for heat treatment and quenching of metal molds, including a processing barrel, which is vertically installed at the other end of the top of a support. The processing barrel has an opening on one side and a cover plate is hinged to it. A hollow cylinder is rotatably arranged inside the processing barrel, and multiple through holes are opened on the arc-shaped surface of the hollow cylinder and are evenly distributed at equal intervals on the surface of the hollow cylinder. A communication mechanism for connecting with a vacuum pump is provided on the hollow cylinder. A rotating mechanism for rotating the hollow cylinder is provided inside the processing barrel, and an automatic cleaning mechanism for cleaning the multiple through holes is also provided inside the processing barrel. An air inlet pipe is connected to one end of the processing barrel. Through the arrangement of the processing barrel and the hollow cylinder, the gas extracted from the vacuum furnace can be filtered before being discharged, which not only avoids the blockage of the vacuum pump pipeline, but also ensures that the discharged gas is clean and environmentally friendly.

[0004] However, using the above method, it is not convenient to adjust the height of the vacuum pump during the heat treatment of the metal mold, which makes it inconvenient to use as the height cannot be adjusted according to the actual situation. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum pump for heat treatment and quenching of metal molds, which allows for easy adjustment of the height of the vacuum pump during the heat treatment process of the metal molds, making it convenient to use as the height can be adjusted according to the actual situation.

[0006] To achieve the above objectives, this utility model provides a vacuum pump for heat treatment and quenching of metal molds, including a support, a treatment barrel, a pump, and a connecting pipe. The treatment barrel is fixedly connected to the support and located on one side of the support. The pump is mounted on the support. One end of the connecting pipe is connected to the pump, and the other end of the connecting pipe is connected to the treatment barrel. The model also includes a height adjustment device.

[0007] The height adjustment device includes a base, a support column, an adjustment column, a drive assembly, and an engagement assembly.

[0009] The drive assembly further includes a bushing, which is fixedly connected to the support column and rotatably connected to the drive rod.

[0010] The meshing assembly includes a meshing plate and a limiting plate. The meshing plate is fixedly connected to the adjusting column and meshes with the driving rod. The limiting plate is fixedly connected to the adjusting column and is located on one side of the adjusting column.

[0011] The support column is provided with a plug rod, which is detachably connected to the support column and detachably connected to the adjustment column.

[0012] This utility model discloses a vacuum pump for heat treatment and quenching of metal molds, comprising a support, a treatment tank, a vacuum pump, a connecting pipe, and a height adjustment device. The height adjustment device includes a base, a support column, an adjustment column, a drive assembly, and a meshing assembly.

[0020] The first embodiment of this application is as follows:

[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of a vacuum pump for heat treatment and quenching of metal molds. Figure 2 This is a front view of the overall vacuum pump used for heat treatment and quenching of metal molds. Figure 3 This is a schematic diagram of the height adjustment device.

The height adjustment device includes a base 105, a support column 106, an adjusting column 107, a drive assembly, and a meshing assembly. The drive assembly includes a drive motor 108, a drive rod 109, and a bushing 110. The meshing assembly includes a meshing plate 111 and a limiting plate 112. A plug-in rod 113 is provided on the support column 106. The aforementioned solution solves the problem of inconvenient height adjustment of the vacuum pump during the heat treatment of metal molds, which prevents height adjustment according to actual conditions and makes use inconvenient. It is understood that the aforementioned solution can facilitate height adjustment of the vacuum pump during the heat treatment of metal molds, allowing for height adjustment according to actual conditions, making it more convenient to use. It can also maintain a stable state after the adjusting column 107 is moved.

[0022] In this specific embodiment, the processing tank 102 is fixedly connected to the support 101 and located on one side of the support 101. The vacuum pump 103 is mounted on the support 101. One end of the connecting pipe 104 is connected to the vacuum pump 103, and the other end of the connecting pipe 104 is connected to the processing tank 102. The processing tank 102 is vertically installed on the top right side of the support 101, and an opening with a hinged cover is provided on one side of the processing tank 102. A hollow cylinder is rotatably disposed inside the processing tank 102, and multiple through holes are provided on the arc-shaped surface of the hollow cylinder, evenly distributed at equal intervals on the surface of the hollow cylinder.

The processing tank 102 is also equipped with an automatic cleaning mechanism for cleaning multiple through holes. An air inlet pipe is connected to one end of the processing tank 102. The air pump 103 is located on the top left side of the support 101. The air pump 103 is connected to the processing tank 102 through the connecting pipe 104. Through the arrangement of the processing tank 102 and the hollow cylinder, the gas extracted from the vacuum furnace can be filtered before being discharged. This not only avoids the air pump 103 pipe from being blocked, but also ensures that the discharged gas is clean and environmentally friendly. All of the above are existing technologies, so this application does not describe them in detail.

[0023] The adjusting column 107 is fixedly connected to the support 101 and located on one side of the support column. The supporting column 106 is slidably connected to the adjusting column 107 and located on one side of the adjusting column 107. The base 105 is fixedly connected to the supporting column 106 and located on one side of the supporting column 106. The driving assembly is disposed on the supporting column 106, and the engaging assembly is disposed on the adjusting column 107. The adjusting column 107 is welded to the bottom center of the support 101. The top of the supporting column 106 has a rectangular opening that extends downward to form a through groove. The adjusting column 107 is located inside the supporting column 106. The bottom end of the supporting column 106 is fixed with the base 105, which supports the supporting column 106, thereby supporting the support 101. The support 101 and the base 105 are parallel to each other. The driving assembly is disposed on the supporting column 106, and the engaging assembly is disposed on the adjusting column 107. Located within the support column 106, the drive assembly is connected to the engagement assembly. When the drive assembly is activated, it drives the adjusting column 107 to move on the support column 106 via the engagement assembly, thereby adjusting the distance between the adjusting column 107 and the support column 106, and consequently adjusting the height of the support 101. This allows the support 101 to adjust the height of the processing tank 102, enabling height adjustment according to actual conditions. The operation is simple. During the heat treatment of metal molds, the equipment is placed horizontally via the support 101. Activating the drive assembly drives the engagement assembly to move the adjusting column 107 on the support column 106, adjusting the distance between the adjusting column 107 and the support column 106, thereby adjusting the height of the support 101, and consequently adjusting the height of the vacuum pump. This allows for height adjustment according to actual conditions, making it convenient to use.

[0024] Secondly, the drive motor 108 is fixedly connected to the support column 106 and located on one side of the support column 106; the drive rod 109 is rotatably connected to the adjusting column 107, and the drive rod 109 is fixedly connected to the output end of the drive motor 108; the bushing 110 is fixedly connected to the support column 106 and rotatably connected to the drive rod 109; the drive motor 108 is fixed to the top right side of the support column 106; the output end of the drive motor 108 is fixed to the right side of the drive rod 109; the drive rod 109 is located inside the support column 106; the bushing 110 is fixed to the left side of the outer surface of the support column 106; the left side of the drive rod 109 passes through the support column 106 into the bushing 110, so that when the drive motor 108 starts, it drives the drive rod 109 to rotate inside the bushing 110.

[0025] Simultaneously, the meshing plate 111 is fixedly connected to the adjusting column 107, and the meshing plate 111 meshes with the driving rod 109; the limiting plate 112 is fixedly connected to the adjusting column 107 and located on one side of the adjusting column 107, the meshing plate 111 is fixed to the rear side of the adjusting column 107, the outer surface of the driving rod 109 has driving teeth, and the side of the meshing plate 111 facing the driving rod 109 has meshing teeth that are adapted to the driving teeth. The driving teeth mesh with the meshing teeth, so that when the drive motor 108 starts, it drives the driving rod 109 to rotate, so that the meshing plate 111 rotates the driving rod 109. Under the meshing action, the plate moves in the direction of rotation of the drive rod 109, thereby causing the meshing plate 111 to drive the adjusting column 107 to move, thereby adjusting the distance between the adjusting column 107 and the support column 106, and thus adjusting the height of the support 101. The bottom end of the adjusting column 107 is welded with the limiting plate 112. The setting of the limiting plate 112 restricts the movement of the adjusting column 107, so that when the adjusting column 107 moves to the uppermost end of the support column 106, the limiting plate 112 prevents the adjusting column 107 from disengaging from the support column 106.

[0026] In addition, the plug-in rod 113 is detachably connected to the support column 106 and the adjusting column 107. The front sides of the adjusting column 107 and the support column 106 are provided with corresponding through holes, which are evenly distributed on the adjusting column 107 and the support column 106. The cross-sectional dimensions of the plug-in rod 113 are adapted to the cross-sectional dimensions of the through holes, so that after the position of the adjusting column 107 is adjusted, the plug-in rod 113 can be inserted from the through hole of the positioning column into the through hole of the adjusting column 107 to fix the adjusting column 107. This allows the adjusting column 107 to maintain a stable state after moving the support 101, which is convenient for subsequent heat treatment of the metal.

[0027] When using the vacuum pump for heat treatment and quenching of a metal mold according to this embodiment, during the heat treatment of the metal mold, the equipment is placed in a horizontal position via the support 101. The drive assembly is then activated, and the drive assembly drives the engagement assembly to move the adjusting column 107 on the support column 106, thereby adjusting the distance between the adjusting column 107 and the support column 106, thus adjusting the height of the support 101, and consequently adjusting the height of the vacuum pump. This allows for height adjustment according to actual conditions, making it convenient to use.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
