Description

Technical Field

[0001] The invention belongs to the technical field of refrigerator box foaming, and in particular relates to a mold and a system for filling a foaming material into a refrigerator box. Background Art

[0002] A refrigerator is a household appliance that keeps food or other items in a constant low-temperature state. It needs to maintain a stable temperature for a long time, so it must have a good insulation effect. In order to ensure that the refrigerator has a good insulation effect, the refrigerator needs to use a double-layer cabinet (i.e., a double-layer cabinet) and fill the double-layer cabinet with foam material to improve its insulation effect.

[0003] The existing refrigerator includes a double-layer cabinet with a refrigeration chamber and a suspended beam arranged in the refrigeration chamber and connected to the inner wall of the double-layer cabinet. During the foaming process, the double-layer cabinet needs to be inverted on the mold core of the mold, and the mold core is used to support the double-layer cabinet and the suspended beam to prevent it from deforming during the foaming process. In order to facilitate the safe removal of the double-layer cabinet carrying the suspended beam after foaming, the existing mold core is forced to consist of a left module, a right module and a middle module, wherein the left module and the right module are respectively located on the left and right sides of the suspended beam, the middle module is located between the left module and the right module and can cover the suspended beam together with the mold base, the left module and the right module, so that when the double-layer cabinet is taken away, the middle module can be taken away through the suspended beam, and the double-layer cabinet is prevented from being blocked by the mold core when it is separated from the mold core. Although the existing mold core can effectively support the double-layer cabinet and the suspended beam during the foaming process, it is necessary to manually take and place the middle module during the foaming process, which not only increases the labor intensity of the operator, but also reduces the efficiency of the refrigerator body foaming process. Summary of the invention

[0004] In order to solve all or part of the above problems, the purpose of the present invention is to provide a mold and a system for filling foaming material into a refrigerator body, so as to solve the problem of low automation level of the foaming process, thereby not only reducing the labor intensity of the operator, but also improving the quality and efficiency of the refrigerator body foaming process.

[0010] Furthermore, a first group of comb teeth is provided on the upper end of the front beam, a second group of comb teeth is provided on the upper end of the rear beam, a third group of comb teeth that intersect with the first group of comb teeth is provided on the front end of the upper beam, and a fourth group of comb teeth that intersect with the second group of comb teeth is provided on the rear end of the upper beam.

[0011] Furthermore, the first driving mechanism includes a driven body arranged in the frame and connected to the upper sliding rod, a front connecting rod passing through the front beam of the frame and hinged to the front beam column and the driven body, and a rear connecting rod passing through the rear beam of the frame and hinged to the rear beam column and the driven body, and a second linear driving component arranged on the sliding platform and connected to the driven body, the second linear driving component can drive the driven body to move from bottom to top, and respectively drive the front beam column, upper beam column and rear beam column through the upper sliding rod, the front connecting rod and the rear connecting rod so that the front beam column, upper beam column and rear beam column are moved away from the frame together, and can also drive the driven body to move from top to bottom, and respectively drive the front beam column, upper beam column and rear beam column through the upper sliding rod, the front connecting rod and the rear connecting rod so that the front beam column, upper beam column and rear beam column are moved close to the frame together.

[0012] Furthermore, the second linear drive assembly includes a hydraulic cylinder, a pneumatic cylinder or a linear motor.

[0013] Further, the mold also includes a sensing component and a control module connected to the first linear drive component and / or the second linear drive component, the sensing component includes: a first sensing module connected to the control module for sensing whether the expansion module is in place and is used to sense whether the expansion module is in place and the control module, wherein the control module can stop the first linear drive component when the first sensing module senses that the expansion module is in place; a second sensing module connected to the control module for sensing whether the expansion module is in place and is used to sense whether the contraction module is in place and the control module, wherein the control module can stop the first linear drive component when the second sensing module senses that the contraction module is in place; a third sensing module connected to the control module for sensing whether the expansion module has completely entered the right module and is used to sense whether the expansion module has completely entered the right module, wherein the control module can stop the second linear drive component when the third sensing module senses that the expansion module has completely entered the right module; and / or a fourth sensing module connected to the control module for sensing whether the expansion module has completely entered between the left module and the right module, wherein the control module can stop the second linear drive component when the fourth sensing module senses that the expansion module has completely entered between the left module and the right module.

[0014] According to a second aspect of the present invention, a system for filling foaming material into a refrigerator cabinet is provided, comprising a mold capable of allowing a refrigerator cabinet to be inverted thereon and a foaming machine capable of filling foaming material into the refrigerator cabinet, wherein the mold is the mold provided by the first aspect of the present invention.

[0015] It can be seen from the above technical scheme that the mold and the system for filling the refrigerator box with foaming material provided by the present invention change the existing middle module into an expansion and contraction module, and add a first driving mechanism that can drive the expansion and contraction module to expand and contract between the left module and the right module and a second driving mechanism that can drive the contracted expansion and contraction module to enter and exit the right module. Before the formal implementation of foaming, the double-layer box with the suspended beam needs to be inverted onto the mold core of the mold. At this time, the expansion and contraction module is in a contracted state and has entered the right module, and the space between the left module and the right module is vacated for the suspended beam to enter, so as to ensure that the double-layer cabinet can be smoothly inverted onto the mold core of the mold. Then, the second driving mechanism needs to move the contracted expansion and contraction module from the right module to between the left and right modules, and the first driving mechanism needs to drive the expansion and contraction module to expand between the left and right modules, so that the expanded expansion and contraction module can not only wrap the suspended beam together with the mold base, the left module and the right module, but also can support the inner wall of the double-layer cabinet together with the left module and the right module, thereby ensuring that the mold core can effectively support the inner wall and the suspended beam of the double-layer cabinet during the foaming process, and avoid deformation of the double-layer cabinet during the foaming process. After the foaming is completed, the first driving mechanism needs to drive the expansion and contraction module to contract between the left and right modules, and the second driving mechanism needs to move the contracted expansion and contraction module from the space between the left and right modules into the right module, and once again vacate the space between the left and right modules for the suspended beam to exit, so as to ensure that the double-layer cabinet can be smoothly removed and safely separated from the mold core of the mold. Compared with the existing molds, the mold has a higher degree of automation, greatly reducing its dependence on manual labor during use, which not only effectively reduces the labor intensity of the operator, but also improves the quality and efficiency of the refrigerator body foaming process. In addition, the mold of the present invention has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a mold 100, which is used to prevent the refrigerator cabinet from deforming when the foaming machine fills the foaming material therein. The refrigerator cabinet includes a double-layer cabinet with a refrigeration chamber and a cantilever beam arranged in the refrigeration chamber and connected to the inner wall of the double-layer cabinet. The mold 100 includes a mold base 20 and a mold core 10 arranged on the mold base 20, and the mold core 10 includes a left module 13, a right module 12 and an expansion and contraction module 11, as well as a first driving mechanism 14 that can drive the expansion and contraction module 11 to expand and contract between the left module 13 and the right module 12 and a second driving mechanism 15 that can drive the contracted expansion and contraction module 11 to enter and exit the right module 12 (see Figure 3 ). When the first driving mechanism 14 moves the contracted expansion and contraction module 11 from the right module 12 into between the left module 13 and the right module 12, the first driving mechanism 14 can drive the expansion and contraction module 11 to expand between the left module 13 and the right module 12, and the expanded expansion and contraction module 11 can not only wrap the suspended beam together with the mold base 20, the left module 13 and the right module 12, but also can support the inner wall of the double-layer cabinet together with the left module 13 and the right module 12.

[0023] According to the embodiment of the present invention, the mold 100 changes the existing middle module into an expansion and contraction module 11, and adds a first drive mechanism 14 that can drive the expansion and contraction module 11 to expand and contract between the left module 13 and the right module 12, and a second drive mechanism 15 that can drive the contracted expansion and contraction module 11 to enter and exit the right module 12. Before the formal implementation of foaming, the double-layer box body with the suspended beam needs to be inverted onto the core 10 of the mold 100. At this time, the expansion and contraction module 11 is in a contracted state and has entered the right module 12, and the space between the left module 13 and the right module 12 is vacated for the suspended beam to enter, so as to ensure that the double-layer cabinet body can be smoothly inverted onto the core 10 of the mold 100. Then, the second driving mechanism 15 needs to move the shrunk expansion and contraction module 11 from the right module 12 into between the left module 13 and the right module 12, and the first driving mechanism 14 needs to drive the expansion and contraction module 11 to expand between the left module 13 and the right module 12, so that the expanded expansion and contraction module 11 can not only wrap the suspended beam together with the mold base 20, the left module 13 and the right module 12, but also can support the inner wall of the double-layer cabinet together with the left module 13 and the right module 12, thereby ensuring that the core 10 can effectively support the inner wall and the suspended beam of the double-layer cabinet during the foaming process, and avoid deformation of the double-layer cabinet during the foaming process. After the foaming is completed, the first driving mechanism 14 needs to drive the expansion and contraction module 11 to contract between the left module 13 and the right module 12, and the second driving mechanism 15 needs to move the contracted expansion and contraction module 11 from the space between the left module 13 and the right module 12 into the right module 12, and once again vacate the space between the left module 13 and the right module 12 for the cantilever beam to exit, so as to ensure that the double-layer cabinet can be smoothly taken away and safely separated from the mold core 10 of the mold 100. Compared with the existing molds, the mold 100 has a higher degree of automation, greatly reducing its dependence on manual labor during use, which not only effectively reduces the labor intensity of the operator, but also improves the quality and efficiency of the refrigerator body foaming process.

[0024] In this embodiment, the second driving mechanism 15 includes a sliding table 151 provided on the mold base 20 and used to carry the expansion and contraction module 11 and the first driving mechanism 14, and a first linear driving component 152 provided on the mold base 20 and used to drive the sliding table 151 to enter and exit the right module 12. In other words, the first linear driving component 152 can drive the sliding table 151 to slide, and the sliding table 151 drives the expansion and contraction module 11 and the first driving mechanism 14 to move together, so that the expansion and contraction module 11 can freely enter and exit the right module 12. The sliding table 151 and the mold base 20 are preferably detachably connected, and the connection method can be bolts or clamping. Among them, the first linear driving component 152 includes a hydraulic cylinder, a pneumatic cylinder or a linear motor. Among them, the first linear driving component 152 is preferably a pneumatic cylinder, which has the advantages of simple structure, reliable operation and smooth movement. In order to enable the sliding table 151 to slide smoothly on the mold base 20, the second driving mechanism 15 may include a sliding guide rail 153 arranged between the mold base 20 and the sliding table 151, and the sliding guide rail 153 can guide the sliding table 151 to slide along the left and right directions and reduce the friction resistance during the sliding process.

When the front beam 111, the upper beam 112 and the rear beam 113 move away from the frame 114, the expansion module 11 is in an expansion state; when the front beam 111, the upper beam 112 and the rear beam 113 move closer to the frame 114, the expansion module 11 is in a contraction state. The front sliding rod 115 of the front beam vertically connected to the front beam column 111 and vertically penetrating the frame 114, the upper sliding rod 116 of the upper beam vertically connected to the upper beam column 112 and vertically penetrating the frame 114, and the rear sliding rod 117 of the rear beam vertically connected to the rear beam column 113 and vertically penetrating the frame 114 can provide guidance for the movement of the front beam column 111, the upper beam column 112 and the rear beam column 113, so that they can move away from the frame 114 or approach the frame 114 together in the corresponding directions.

Through this cross-comb tooth matching, on the one hand, it can be ensured that the expansion and contraction module 11 has a larger area to support the inner wall of the double-layer cabinet after expansion, and more safely prevent the inner wall from deforming during the foaming process, and on the other hand, it can be ensured that the expansion and contraction module 11 has a smaller volume after contraction, so that it is easier and safer to enter the right module 12.

[0027] In this embodiment, the first driving mechanism 14 includes a driven body 141 arranged in the frame 114 and connected to the upper sliding rod 116, a front connecting rod 142 passing through the front beam of the frame 114 and hinged to the front beam column 111 and the driven body 141, and a rear connecting rod 143 passing through the rear beam of the frame 114 and hinged to the rear beam column 113 and the driven body 141, and a second linear driving component 144 arranged on the sliding table 151 and connected to the driven body 141.

The sensing component includes a first sensing module, a second sensing module 31, a third sensing module and / or a fourth sensing module 32, see Figure 4The first sensing module is used to sense whether the expansion module 11 is fully expanded and connected to the control module, so that the control module can stop the first linear drive assembly 152 when the first sensing module senses that the expansion module 11 is fully expanded. The second sensing module 31 is used to sense whether the expansion module 11 is fully contracted and connected to the control module, so that the control module can stop the first linear drive assembly 152 when the second sensing module 31 senses that the contraction of the expansion module 11 is fully contracted.

The control module can be an industrial computer or a PLC controller. Since the PLC controller has the advantages of low cost and high reliability, the PLC controller is selected as the preferred one. The first sensing module, the second sensing module 31, the third sensing module and the fourth sensing module 32 can all be selected as travel switches. The travel switch has the advantages of simple structure, practical function and low price, so the travel switch is the best choice for each sensing module.
