Description

Technical Field

[0001] This invention relates to the field of foaming technology for the housing of refrigeration and freezing equipment, and in particular to a foaming mold for the housing of refrigeration and freezing equipment and its control system. Background Technology

[0002] In the production of refrigeration and freezing equipment, to improve the internal insulation of the unit's interior, foam material is typically injected into the cabinet. This foam fills the internal space, achieving good insulation. To achieve even better insulation, a mold core matching the internal structure of the cabinet is usually designed for precise foaming. However, some technologies suffer from issues where the weight of the cabinet's central beams causes depressions, leading to poor fit between the cabinet and doors, resulting in condensation and cold leakage.

[0003] Existing technologies typically address this issue by adding support rods inside the beam of the foaming mold. However, this method increases the number of processes and raises costs. Furthermore, during the actual foaming process, the expansion of the foaming material often leads to poor connection of the support rods and easily results in unevenness in the foamed beam. Summary of the Invention

[0025] The second end plate is located on the outer side of the other end of the housing; a second punch core is provided on the inner side of the second end plate.

[0026] Two side panels are respectively disposed on both sides of the box body; and

[0034] Furthermore, the foaming mold for the cabinet of the refrigeration and freezing device provided in this embodiment of the invention uses multiple distance detection devices. By combining the distances between the corresponding center beams detected by different distance detection devices and the corresponding distance detection devices, the concavity degree of the center beams can be analyzed, resulting in a more accurate result.

[0035] Furthermore, after moving the movable suction part to the appropriate position, it is fixed by a locking mechanism or a self-locking mechanism, and then the center beam is targeted for suction correction.

[0051] Figure 1 This is a schematic structural diagram of a foaming mold for a refrigerator / freezer housing according to an embodiment of the present invention, as shown below. Figure 1 As shown and referenced Figures 2 to 7 This invention provides a foaming mold for a refrigerator / freezer housing. The foaming mold includes an upper side plate 100 and suction devices 200. The upper side plate 100 is disposed on the upper side of the refrigerator / freezer housing 300 to be foamed. The housing 300 is horizontally positioned with its opening facing upwards during foaming. At least one suction device 200 is provided, and each suction device 200 is mounted on the upper side plate 100. Each suction device 200 is configured to suction upwards a central beam 400 of the housing 300, such that at least one location on the central beam 400 is at a predetermined distance from the upper side plate 100.

[0052] In the foaming mold for the housing 300 of the refrigeration and freezing device provided in this embodiment of the invention, an upper side plate 100 is provided on the upper side of the housing 300 to be foamed in the refrigeration and freezing device. A suction device 200 is installed on the upper side plate 100. The suction device 200 attracts the central beam 400 of the housing 300 upward, thereby overcoming the weight of the central beam 400 itself, effectively solving problems such as concavity and gaps in the central beam 400 of the housing. This avoids leakage problems and poor assembly problems in the refrigeration and freezing device.

[0053] In some embodiments of the present invention, each suction device 200 includes at least one suction part 210, each suction part 210 being configured to suction a corresponding position on the center beam 400. The suction force of each suction part 210 is adjustable. Preferably, each suction part 210 is a suction cup device, which can be an electromagnetic suction cup device or a pneumatic suction cup device. Specifically, the suction force of the suction part 210 provided in the embodiments of the present invention can be precisely adjusted according to the degree of concavity of the center beam 400. The electromagnetic suction cup device can adjust the suction force by changing the voltage and / or current; the pneumatic suction cup can adjust the suction force by changing the vacuum level within the suction cup. This embodiment provides a variety of suction cup devices, which can be selected according to the needs of different refrigeration and freezing devices to meet the requirements of different types of center beam 400 components when solving the problem of concavity in the center beam 400. More solutions are provided to address the problem of concavity in the center beam 400.

[0054] In some embodiments of the invention, at least one suction part 210 includes at least one movable suction part, each movable suction part being movably mounted to the upper side plate 100 along the length direction of the corresponding center beam 400. In some alternative embodiments, at least one suction part 210 includes at least one fixed suction part, each fixed suction part being fixedly mounted to the upper side plate 100.

[0055] In some alternative embodiments, at least one suction part 210 includes at least one movable suction part and at least one fixed suction part. When suctioning the center beam 400, the movable and fixed suction parts cooperate to select several severely concave areas of the center beam 400 for suction, and match an appropriate suction force to solve the concavity problem of the center beam 400. In particular, due to the use of suction parts with adjustable suction force and precise selection of suction position 200, the solution to the concavity problem of the center beam 400 is more precise and professional.

[0056] In some embodiments of the present invention, the foaming mold further includes at least one center beam concavity detection device 500, each center beam concavity detection device 500 being configured to detect the concavity of the center beam to determine the suction position and / or suction force of the center beam 400 by the suction device based on the concavity of the center beam 400.

[0057] When applied, the foaming mold provided in this embodiment of the invention can accurately detect the degree of concavity of the central beam 400 through the central beam concavity detection device 500. Combined with the aforementioned suction part 210, it can precisely select severely concave areas for suction and adjust the suction force to an appropriate level to accurately suction the central beam 400. In particular, because the central beam concavity detection device 500 is used, it can effectively detect the degree of concavity in different parts of the central beam 400 for targeted suction correction and match an appropriate suction force. This prevents insufficient suction from causing failure to suction and also prevents defects such as marks or deformation on the central beam due to excessive suction, making it more efficient.

[0058] In some embodiments of the present invention, see Figure 3 As shown, at least one guide rail 600 is provided on the upper side plate 100, and each guide rail 600 is correspondingly provided with one center beam 400. Each movable engaging part is installed on the guide rail 600. Alternatively, at least one mounting groove is provided on the upper side plate 100, and each mounting groove is aligned with one center beam 400. Further, each guide rail 600 is installed in one mounting groove.

[0059] Specifically, a movable suction part is installed on the upper side plate via a guide rail 600. During application, the movable suction part can be moved to the appropriate position on the guide rail 600 to perform targeted suction correction on the center beam 400, resulting in more precise correction of the concave shape of the center beam 400.

[0060] In some embodiments of the present invention, each guide rail 600 is provided with a plurality of guide rail holes 630 perpendicular to the upper side plate 100. Each center beam recess detection device 500 includes a plurality of distance detection devices 510, each distance detection device 510 being mounted in one guide rail hole 630 and configured to detect the distance between the corresponding center beam 400 and the distance detection device 510. Alternatively, each distance detection device 510 is disposed on the front side of the guide rail 600 and configured to detect the distance between the corresponding center beam 400 and the distance detection device 510 through one guide rail hole 630. Each distance detection device 510 is a laser detection device, an infrared detection device, or radar.

[0061] In application, the foaming mold provided in this embodiment of the invention employs multiple distance detection devices 510. By combining the distances between the corresponding center beam 400 and the detection device 510 detected by different distance detection devices 510, the degree of concavity of the center beam 400 can be analyzed, resulting in more accurate results and more precise correction of the center beam 400 through suction. Specifically, this embodiment provides multiple distance detection devices 510, which can be selected according to the needs of different refrigeration and freezing devices to meet the requirements of different types of center beam components when solving the problem of center beam 400 concavity. This provides more solutions to the problem of center beam 400 concavity.

[0062] In some embodiments of the present invention, each movable engaging part is mounted on the guide rail 600 via a slider 700. Each slider 700 engages with a lead screw parallel to the guide rail 600, so that the lead screw, when rotated, drives the slider 700 to move along the guide rail 600. Each slider 700 is fixed to the corresponding guide rail 600 after moving to the corresponding position via a locking mechanism or a self-locking mechanism. Further, the locking mechanism or self-locking mechanism may be two spring plates that clamp the guide rail 600 when not moving, but can be pulled without affecting movement; or the locking mechanism may be a friction mechanism that only moves after overcoming sufficient friction, and can stop at any position.

[0063] In application, the foaming mold provided in this embodiment of the invention, after the movable suction part moves to the appropriate position, is fixed by a locking mechanism or a self-locking mechanism, and then the central beam 400 is targeted for suction correction. Because a locking mechanism or self-locking mechanism is used for fixation, instability and shaking of the movable suction part during the suction process are avoided, resulting in a better suction effect.

[0064] In some embodiments of the present invention, see Figure 5 , Figure 6 As shown, the foaming mold also includes a first punch core 800, a first end plate 910, a second end plate 920, a side plate 930, and a bottom plate 940. Multiple first punch cores 800 are disposed on the lower side of the upper side plate 100. The first end plate 910 is disposed on the outer side of one end of the housing 300. The second end plate 920 is disposed on the outer side of the other end of the housing 300. A second punch core is disposed on the inner side of the second end plate. Two side plates 930 are disposed on both sides of the housing. The bottom plate 940 is disposed on the lower side of the housing 300. The first punch cores 800 are used to cooperate with the internal space of the inner liner of the housing, and the second punch cores are used to cooperate with the compressor compartment of the housing.

[0065] In some embodiments of the present invention, preferably, there are two center beams, namely a horizontal center beam and a vertical center beam, then there are two corresponding suction devices 200, two center beam concavity detection devices 500, and two guide rails 600, namely a horizontal guide rail 610 and a vertical guide rail 620.

[0066] The present invention also provides a control system, including a lower-level machine 1010, a mold opening and closing instruction module 1030, and a higher-level machine 1020.

[0067] The mold opening / closing instruction module 1030 is configured to send a mold closing signal to the lower-level computer 1010. The foaming box is pushed into the foaming mold along the conveyor chain, and the foaming mold will close inwards. This state is the pre-foaming preparation stage; the next stage will be foaming. Then, the mold opening / closing instruction module 1030 sends a mold closing signal to the lower-level computer 1010, indicating that mold closing is complete.

[0068] After receiving the mold closing signal, the lower computer 1010 controls the middle beam concavity detection device 500 to start. The middle beam concavity detection device 500 sends the detection result to the lower computer 1010 through the data transmission line 520, and the lower computer 1010 transmits the data to the upper computer 1020.

[0069] The host computer 1020 is configured to receive the detection results from the center beam concavity detection device 500 sent by the slave computer 1010, and obtain the suction position and / or suction force of each center beam by the corresponding suction device 200 based on the detection results of the center beam concavity detection device 500, and send control commands to the slave computer. The slave computer 1010, according to the control commands, moves the suction device 200 to the corresponding suction position and / or generates the corresponding suction force. The suction device 200 feeds back the corresponding suction position and / or the generated corresponding suction force to the slave computer 1010, which then feeds back to the host computer 1020. The slave computer 1010 and the host computer 1020 can communicate via RS-485 or UART.

[0070] Specifically, because a control system is used to control the entire suction process, effective data analysis, fault alarms, data troubleshooting, and data statistics can be performed. This allows for precise detection of the degree of concavity in different parts of the central beam, enabling targeted suction correction and resulting in greater accuracy. In some embodiments of this invention, the control system also includes a terminal that communicates with a host computer via a cloud platform. The terminal can be a mobile device or a computer.

[0071] In some embodiments of the present invention, the control system is also connected to a terminal and a host computer module via a cloud platform, enabling the management of the entire work process through mobile and / or computer terminals. This includes functions such as controlling operating permissions, statistically analyzing, organizing, investigating, and examining data from the entire control module, outputting daily reports, and issuing alarms for abnormal situations. This achieves visualization, automation, and systematization in mold operation.

[0072] Specifically, such as Figure 7As shown, after the foaming mold is closed and the pre-foaming preparation stage is completed, the mold opening / closing signal module inputs a mold closing signal to the lower-level computer 1010. Upon receiving the mold closing signal, the lower-level computer 1010 controls multiple infrared or laser detection devices within the foaming mold to activate a pre-set automatic ranging mode. After measurement, the measurement results are fed back to the lower-level computer 1010 via the data transmission line 520. The lower-level computer 1010 then uploads the measurement data to the upper-level computer 1020 for rapid analysis. Simultaneously, technicians use a terminal connected to the upper-level computer 1020 to check for any abnormal data and save all data to the terminal for statistical recording.

[0073] The host computer 1020 analyzes and identifies several reasonable correction points for deformation. It then converts this analysis data into control commands and sends them to the slave computer 1010. The slave computer 1010, following these commands, first moves the movable suction unit to the designated correction point, then engages it, simultaneously adjusting the suction force to effectively counteract the gravity of the central beam. At the same time, the movable suction unit feeds back the suction force data to the slave computer 1010. The foaming mold then begins foaming via the injection gun. By setting a suitable foaming time for the slave computer 1010, after foaming is complete, the slave computer 1010 automatically initiates a command to disengage the movable suction unit and then resets it. Finally, the mold is opened via a command opening / closing signal module, and the foamed refrigeration unit exits the mold, completing the entire foaming process.

[0074] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
