Description

Technical Field

[0001] The utility model relates to the field of vacuum technology, in particular to a sub-control box with hydraulic mechanical valve control. Background Art

[0002] Currently, in plastic injection molding, metal casting molding or other related industrial fields, there is a growing demand for vacuuming inside the mold cavity, which helps to improve product quality and reduce defects such as bubbles and dents. Traditional vacuum control solutions often use a single control method, such as pure mechanical control or pure hydraulic control, which have their own limitations:

[0003] Limitations of a single control mode: Traditional vacuum control units mostly rely on only one control method. For example, pure mechanical control has a simple structure and low cost, but has a slow response speed, limited control accuracy, and is difficult to achieve remote or automated control. Pure hydraulic control can provide fast and accurate control, but the system is complex, costly, and requires a high level of maintenance, increasing the risk of leakage and failure.

[0004] Size and installation flexibility issues: Previous vacuum control devices are often large in size and not easy to integrate into compact production lines. Especially when the production line needs to frequently adjust the layout or change the mold, the bulky control box becomes one of the limiting factors.

[0005] Difficulty of maintenance and repair: Due to the complex structure or low integration of some traditional designs, once a failure occurs, it takes a long time to locate the problem, and the repair process may involve the disassembly and assembly of multiple components, increasing downtime and maintenance costs.

[0006] Single function: Many vacuum control units in existing technologies cannot flexibly adapt to different production needs, especially when it is necessary to quickly switch production modes or product types, and lack sufficient flexibility to optimize vacuum control strategies.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0031] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0032] In order to solve the problems of single control mode, large volume and difficult maintenance of vacuum valves in sub-control boxes in the prior art, the utility model provides a sub-control box with hydraulic mechanical valve control.

[0033] like Figure 1-3 As shown, the utility model provides a sub-control box with hydraulic mechanical valve control, including a box body 1, a filter assembly 2, a mechanical valve 3, a hydraulic valve 4 and a vacuum exhaust valve 5 arranged in series.

[0034] Specifically, the box body 1 is provided with a vacuum suction interface 11 and an internal flow channel 12. The internal flow channel is located inside the box body 1. The internal flow channel 12 has a first end connected to the vacuum suction interface 11 and a second end passing through the box body.

[0035] The filter assembly 2 is arranged on the housing 1 and has an access port 21 communicating with the interior of the filter assembly 2 and the interior of the mold cavity, and a connecting channel 22 communicating with the interior of the filter assembly 2 and the second end.

[0036] It can be understood that when it is necessary to extract air from the inside of the mold cavity, the extracted air enters the filter assembly 2 through the inlet 21, where it can be filtered to remove foreign matter, impurities, etc.; then, it enters the internal flow channel 12 of the box body 1 through the connecting channel 22, and finally flows out from the vacuum suction interface 11 connected to the internal flow channel 12 and communicates with the negative pressure system.

[0037] Further, the vacuum exhaust valve 5 is arranged on the vacuum suction interface 11 to open and close the vacuum suction interface 11, and the mechanical valve 3 and the hydraulic valve 4 are arranged on the internal flow channel 11 to open and close the internal flow channel 11, wherein the mechanical valve 3 is arranged close to the connecting channel 22, and the sub-control box with hydraulic mechanical valve control has a first state and a second state, in the first state, the mechanical valve 3, the hydraulic valve 4 and the vacuum exhaust valve 5 can be driven to open at the same time, so that the flow channel from the inside of the mold cavity to the vacuum suction interface 11 is in an open state, so that the inside of the mold cavity can be vacuumed; in the second state, at least one of the mechanical valve, the hydraulic valve and the vacuum exhaust valve can be driven to close. It can be understood that after the vacuuming is completed, any one of the mechanical valve 3, the hydraulic valve 4 and the vacuum exhaust valve 5 can be closed to cut off the flow channel leading to the vacuum suction interface 11, so as to maintain the inside of the mold cavity in a closed state.

[0038] Among them, the mechanical valve 3 is arranged close to the connecting channel 22. The mechanical valve 3 has a simple structure, low cost, easy operation, and slow response speed. Therefore, the mechanical valve 3 can be closed when the molten metal liquid enters a certain position in the mold cavity, thereby achieving the expected sealing effect; the hydraulic valve 4 has high precision and can adapt to the operation settings under high precision conditions; the vacuum exhaust valve 5 has good remote operability and fast responsiveness, and can effectively protect the negative pressure system connected to the vacuum suction interface 11.

[0039] Through the above settings, the sub-control box can switch between multiple modes and achieve the effects of small size and flexible installation.

[0040] Further, refer to Figure 1 As shown in FIG. 3 , the sub-control box with hydraulic mechanical valve control also includes a purging system, which includes a compressed gas inlet 61 provided on the box body 1, a purging channel 62 connecting the compressed gas inlet 61 and the internal flow channel 11, and a purging control valve 63 provided on the purging channel, wherein the purging control valve 63 is used to control the opening and closing of the purging channel 62. When the inside of the mold cavity is not in a non-vacuum state, that is, the mold is not in the processing process, the mechanical valve 3 and the hydraulic valve 4 can be opened at the same time, the vacuum exhaust valve 5 can be closed, and the purging control valve 63 can be opened, so that the inside of the internal flow channel 11, the inside of the filter assembly 2 and the inside of the mold cavity can be purged by high-pressure gas, and the flow path of the high-pressure gas is, in sequence, the compressed gas inlet 61, the purging channel 62, the internal flow channel 11, the inside of the filter assembly 2 and the inside of the mold cavity.

[0041] Preferably, the purging system also includes a connecting pipe 64, the purging channel 62 includes a main channel 621 and a branch channel 622, the main channel 621 connects the compressed gas inlet 61 and the internal channel 11, the purging control valve 63 is arranged on the main channel 621, one end of the branch channel 622 is connected to the main channel 621, and the other end is connected to the interior of the filter assembly 2 through the connecting pipe 64, and the purging control valve 63 can be driven to simultaneously control the main channel 621 and the branch channel 622 to open or close.

[0042] It can be understood that high-pressure gas can be directly connected to the interior of the filter assembly 2 through the branch channel 622 and the connecting pipe 64, which reduces the mileage of the high-pressure gas. Combined with the high-pressure gas flowing into the interior of the filter assembly 2 through the internal flow channel 11, the interior of the filter assembly 2 can be cleaned at different angles and intensities, thereby achieving a better cleaning effect.

[0043] Optionally, the compressed gas inlet 61 is also connected to a gas source (not shown in the figure), and the gas source is set to be compressed gas.

[0044] Optionally, the vacuum suction interface 12 is also connected to a negative pressure system (not shown in the figure), and the negative pressure system can be configured as a vacuum pump.

[0045] Further, refer to Figure 1 As shown in FIG. 2 , the sub-control box with hydraulic mechanical valve control also includes an electrical control unit electrically connected to the vacuum exhaust valve 5 , and the electrical control unit includes a ten-core heavy-duty connector 51 and a sixteen-core heavy-duty connector 51 .

[0046] Correspondingly, the sub-control box with hydraulic mechanical valve control also includes a hydraulic valve control unit for controlling the opening and closing of the hydraulic valve 4. The hydraulic valve control unit includes a hydraulic accumulator 41, a hydraulic reversing valve group 42 and a hydraulic valve control valve block 43 that are arranged in coordination with each other.

[0047] Furthermore, the sub-control box with hydraulic mechanical valve control further includes a mechanical valve control interface 31 and a mechanical valve control unit (not shown in the figure), and the mechanical valve control unit is arranged on the mechanical valve control interface 31 .

[0048] In summary, the embodiments of the present invention achieve the following technical effects:

[0049] The mechanical valve 3 is arranged close to the connecting channel 22. The mechanical valve 3 has a simple structure, low cost, is easy to operate, and has a slow response speed. Therefore, the mechanical valve 3 can be closed when the molten metal liquid enters a certain position in the mold cavity, thereby achieving the expected sealing effect; the hydraulic valve 4 has high precision and can adapt to the operation settings under high precision conditions; the vacuum exhaust valve 5 has good remote operability and fast responsiveness, and can effectively protect the negative pressure system connected to the vacuum suction interface 11.
