Description

Technical Field

[0001] This invention relates to the field of foaming mold opening device technology, specifically to a foaming device for refrigerator processing. Background Technology

[0002] The refrigerator door consists of upper and lower side clips, a door shell, a door liner, and foaming liquid. The upper and lower side clips have slots that are inserted into both ends of the door shell. The installation of the door liner and foaming liquid requires a mold. The assembled side clips and door shell are placed in the upper mold, and the door liner is placed in the lower mold. When the mold is opened, the foaming machine injects the prepared foaming liquid into the door liner. When the mold is closed, the foaming liquid expands and contracts to solidify, combining the door liner, side clips, and door shell into a complete refrigerator door.

[0003] In this production process, the upper mold needs to be opened and closed manually repeatedly. Due to the large number of molds and their heavy weight, the repeated manual operation not only increases physical exertion but also reduces production efficiency.

[0004] Referring to Chinese Patent Application No. CN201822030209.9, a mold opening device for a refrigerator door foaming mold is disclosed. This patent uses a motor as a drive mechanism to move the upper mold plate up and down, thereby opening and closing the mold, so as to reduce the workload of workers. The limiting post provided on the lower surface of the upper mold plate and the limiting groove provided on the upper surface of the lower mold plate can ensure that the upper and lower mold plates can be accurately aligned when the mold is closed, thus ensuring the quality of the product.

[0005] Regarding the aforementioned related technologies, the inventors discovered that after the mold is formed, the mold may stick together between the upper and lower mold plates. Therefore, manually removing the mold during the mold removal process is too physically demanding and detrimental to mold production. Summary of the Invention

[0006] In view of this, the present invention provides a foaming device for refrigerator processing, which reduces the workload of workers and facilitates mold production.

[0007] To solve the above technical problems, the present invention provides a foaming device for refrigerator processing, comprising: a frame, a connecting plate fixedly connected to one side of the top of the frame, an upper mold fixedly connected to one end of the connecting plate and the frame, and a lower mold hinged to the bottom of the upper mold on the side away from the connecting plate; a first connecting rod disposed on the side of the lower mold away from the hinge point of the upper mold and fixedly connected to two side walls along the length direction of the lower mold; a first linear actuator fixedly mounted on the two ends of the first connecting rod away from the lower mold, the output shaft of the first linear actuator being hinged to a second connecting rod fixedly connected to the frame; and a release plate hinged to the connecting plate near the lower mold. The upper mold has a bottom wall; a connecting block, fixedly connected to the bottom wall of the connecting plate away from the demolding template, the connecting block being hinged to an mounting block, and a second linear actuator being fixedly mounted on one end of the mounting block away from the connecting block, and two second linear actuators are provided, the output shafts of the two second linear actuators being fixedly connected to push-pull rods hinged to the demolding template; a filling mechanism, located below the upper mold, for filling the upper mold and the lower mold; and a cleaning mechanism, located at the connection between the connecting plate and the upper mold, for cleaning the demolding template; wherein, the filling mechanism enables the refrigerator door to be demolded and cleans the upper mold and the lower mold.

[0008] By adopting the above technical solution, foaming liquid is first filled between the upper and lower molds by the filling mechanism. After filling is completed, the first linear drive is activated to move the lower mold downwards. Then, the second linear drive is activated to rotate the demolding template to facilitate mold release. The filling mechanism is then activated to increase the probability of mold release. After the mold is released, it falls onto the lower mold. Finally, the mold is transported to the next processing site. The upper and lower molds are then cleaned by the filling mechanism, and the demolding template is cleaned by the cleaning mechanism to facilitate the production of the next mold. This device does not require manual demolding, thereby reducing the workload of workers.

[0009] The filling mechanism facilitates mold demolding after the foaming liquid is filled, and also allows for the cleaning of the upper and lower molds. This not only saves energy and space but also improves work efficiency.

[0010] Optionally, the filling mechanism includes: a third linear actuator, fixedly installed on the bottom wall of the upper mold away from the demolding plate, the output shaft of the third linear actuator being fixedly connected to an arc-shaped spade; and multiple foam guns, fixedly installed on the arc-shaped spade, for filling foaming liquid between the upper mold and the lower mold; wherein, when the arc-shaped spade moves, it abuts against the upper mold and the lower mold and cleans the upper mold and the lower mold.

[0011] By adopting the above technical solution, when foaming liquid needs to be filled, the third linear actuator is first activated to drive the arc-shaped shovel plate to move horizontally. Then, during the movement of the arc-shaped shovel plate, foaming liquid is filled between the upper and lower molds through the foam gun. The foam gun fills while moving and keeps the filling space under negative pressure, which is conducive to the uniform expansion of the foaming liquid. When the filling is completed, the third linear actuator is activated to drive the arc-shaped shovel plate to move, which can scrape the mold, thus facilitating mold demolding. After the mold is demolded, the third linear actuator is activated to drive the arc-shaped shovel plate to move. Since the arc-shaped shovel plate abuts against the upper and lower molds, it can clean the upper and lower molds.

[0012] The curved spade plate allows the mold to be demolded after molding, and also allows for cleaning of the upper and lower molds after demolding, thus improving work efficiency.

[0013] Optionally, the cleaning mechanism includes: a third connecting rod, fixedly connected to the vertical side wall of the upper mold; a fourth linear actuator, fixedly installed at the end of the third connecting rod away from the upper mold; and a cleaning plate, fixedly connected to the output shaft of the fourth linear actuator and abutting against the stripping plate.

[0014] By adopting the above technical solution, when it is necessary to clean the stripping template, the fourth linear driver is first started. Then, the output shaft of the fourth linear driver drives the cleaning plate to move. Then, the cleaning plate comes into contact with the stripping template during the movement, thereby cleaning the stripping template to facilitate the next processing of the mold.

[0015] The cleaning plate and the arc-shaped shovel work together to clean the device, facilitating the production of the next mold and thus improving work efficiency.

[0016] Optionally, the top of the upper mold is provided with a cutting mechanism for dividing the mold.

[0017] By adopting the above technical solution, the cutting mechanism can cut the formed mold, thereby enabling the production of two molds at once, which in turn improves work efficiency.

[0018] Optionally, the cutting mechanism includes: a support frame, fixedly connected to the top of the upper mold; a fifth linear drive, fixedly mounted on the support frame and having multiple drives; and a cutter, fixedly connected to the output shaft of the fifth linear drive and passing through the upper mold.

[0019] By adopting the above technical solution, when it is necessary to cut the mold, the fifth linear driver is started first, and then the output shaft of the fifth linear driver drives the cutter to cut the mold, so that two molds can be produced at one time, which is conducive to improving work efficiency.

[0020] Optionally, a demolding mechanism for demolding the mold is provided at the connection between the connecting plate and the upper mold.

[0021] By adopting the above technical solution, the demolding mechanism can facilitate demolding after the mold is formed, thereby reducing the workload of workers.

[0022] Optionally, the demolding mechanism includes: a groove formed on the bottom wall of the upper mold near the connecting plate, with a connecting column fixedly connected to the top of the groove; a return spring sleeved on the connecting column; and a push plate hinged to the upper mold, with the return spring fixedly connected between the upper mold and the push plate, the push plate abutting against the demolding template; wherein, there are two demolding mechanisms and they are located on both sides of the bottom of the lower mold.

[0023] By adopting the above technical solution, when it is necessary to demold the mold, the demolding plate rotates first, and the reset spring drives the push plate to move, thereby pushing the mold after molding, and then demolding the mold.

[0024] The push plate and the arc-shaped shovel plate work together to demold the mold after molding, which helps to reduce the workload of the workers.

[0025] Optionally, the cleaning mechanism is configured as two and is located on both sides of the lower mold.

[0026] By adopting the above technical solution, two cleaning mechanisms are set up to clean the template simultaneously, thereby reducing cleaning time and improving work efficiency.

[0027] Optionally, the cutting mechanism may be configured as multiple.

[0028] By adopting the above technical solution, the setting of multiple cutting mechanisms can process multiple molds simultaneously, thereby improving work efficiency.

[0029] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0030] 1. The filling mechanism facilitates mold demolding after filling with foaming liquid, and also allows for cleaning of the upper and lower molds. This not only saves energy and space but also improves work efficiency.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-4 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0040] Reference Figure 1 and Figure 2A foaming device for refrigerator processing includes a frame 1 erected on a horizontal plane. A connecting plate 12 is fixedly connected to one side of the top of the frame 1. An upper mold 2 is fixedly connected between one end of the connecting plate 12 and the frame 1. The upper mold 2 is a cuboid plate, and two cuboid plates are fixedly connected to its two bottom walls along its length. A lower mold 3 is hinged to the bottom of the upper mold 2 away from the connecting plate 12. A first connecting rod 31 is provided on the side of the lower mold 3 away from the hinge point of the upper mold 2 and the lower mold 3, and the first connecting rod 31 is fixedly connected to two side walls along the length of the lower mold 3. The two first connecting rods 31 are located away from the two side walls along the length of the lower mold 3. A first linear actuator 32 is fixedly installed at one end of the lower mold 3. The output shaft of the first linear actuator 32 is hinged to a second connecting rod 33 fixedly connected to the frame 1. A stripping template 4 is hinged to the bottom wall of the connecting plate 12 near the upper mold 2. A connecting block 5 is fixedly connected to the bottom wall of the connecting plate 12 away from the stripping template 4. An installation block 51 is hinged to the end of the connecting block 5 away from the stripping template 4. A second linear actuator 52 is fixedly installed at the end of the installation block 51 away from the connecting block 5. There are two second linear actuators 52. The output shafts of the two second linear actuators 52 are fixedly connected to push-pull rods 53 hinged to the stripping template 4.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A filling mechanism 6 is provided below the upper mold 2 for filling the upper mold 2 and the lower mold 3. Cleaning mechanisms 7 are provided on both sides of the connection between the connecting plate 12 and the upper mold 2 for cleaning the demolding template 4. Multiple cutting mechanisms 8 are provided on the top of the upper mold 2 for dividing the mold. Demolding mechanisms 9 are provided on both sides of the connection between the connecting plate 12 and the upper mold 2 for demolding the mold. Among them, the filling mechanism 6 can demold the refrigerator door and clean the upper mold 2 and the lower mold 3.

[0042] When mold production is required, foaming liquid is first filled between the upper mold 2 and the lower mold 3 by the filling mechanism 6. After filling, the first linear drive 32 is activated to move the lower mold 3 downward. Then, the second linear drive 52 is activated to rotate the demolding template 4 to facilitate mold release. The filling mechanism 6 and the demolding mechanism 9 are then activated to increase the probability of mold release. After release, the mold falls onto the lower mold 3 and is then transported to the next processing area. The filling mechanism 6 cleans the upper mold 2 and the lower mold 3, and the cleaning mechanism 7 cleans the demolding template 4 to facilitate the production of the next mold. This device does not require manual demolding, thus reducing the workload of workers. If multiple molds need to be produced simultaneously, multiple cutting mechanisms 8 can be used to cut the molds after molding, thereby improving work efficiency.

[0043] Reference Figure 1 and Figure 2The filling mechanism 6 includes a third linear actuator 61 fixedly installed on the bottom wall of the upper mold 2 away from the demolding template 4. The output shaft of the third linear actuator 61 is fixedly connected to an arc-shaped spade 62. Multiple foaming guns 63 for filling foaming liquid between the upper mold 2 and the lower mold 3 are fixedly installed on the arc-shaped spade 62. When the arc-shaped spade 62 moves, it abuts against the upper mold 2 and the lower mold 3 and cleans the upper mold 2 and the lower mold 3.

[0044] When foaming liquid needs to be filled, the third linear actuator 61 is first activated to move the arc-shaped shovel 62 horizontally. Then, during the movement, the arc-shaped shovel 62 fills the space between the upper mold 2 and the lower mold 3 with foaming liquid through the foam gun 63. The foam gun 63 fills the space while moving and keeps the filling space under negative pressure, which is conducive to the uniform expansion of the foaming liquid. When the filling is completed, the third linear actuator 61 is activated to move the arc-shaped shovel 62, which can scrape the mold, thus facilitating mold demolding. After the mold is demolded, the third linear actuator 61 is activated to move the arc-shaped shovel 62. Since the arc-shaped shovel 62 abuts against the upper mold 2 and the lower mold 3, it can clean the upper mold 2 and the lower mold 3.

[0045] Reference Figure 1 and Figure 2 The cleaning mechanism 7 includes a third connecting rod 71 fixedly connected to the vertical side wall of the upper mold 2. A fourth linear actuator 72 is fixedly installed at the end of the third connecting rod 71 away from the upper mold 2. The output shaft of the fourth linear actuator 72 is fixedly connected to a cleaning plate 73 that abuts against the ejector plate 4. When it is necessary to clean the ejector plate 4, the fourth linear actuator 72 is first activated. Then, the output shaft of the fourth linear actuator 72 drives the cleaning plate 73 to move. During the movement, the cleaning plate 73 abuts against the ejector plate 4, thereby cleaning the ejector plate 4 to facilitate the next processing of the mold.

[0046] Reference Figure 1 The cutting mechanism 8 includes a support frame 81 fixedly connected to the top of the upper mold 2. The support frame 81 is U-shaped, and multiple fifth linear actuators 82 are fixedly mounted on the support frame 81. The output shafts of the fifth linear actuators 82 are fixedly connected to cutters 83, and the cutters 83 pass through the upper mold 2. When cutting the mold is required, the fifth linear actuators 82 are first activated, and then the output shafts of the fifth linear actuators 82 drive the cutters 83 to cut the mold, thereby enabling the production of two molds at once, which improves work efficiency.

[0047] Reference Figure 3 and Figure 4The demolding mechanism 9 includes a groove 91 formed on the bottom wall of the upper mold 2 near the connecting plate 12. A connecting column 92 is fixedly connected to the top wall of the groove 91, and a return spring 93 is sleeved on the connecting column 92. The upper mold 2 is hinged to a push plate 94 that abuts against the demolding template 4, and the return spring 93 is fixedly connected between the upper mold 2 and the push plate 94. Two demolding mechanisms 9 are provided and located on both sides of the bottom of the lower mold 3. When demolding is required, the demolding template 4 rotates first, and the return spring 93 drives the push plate 94 to move, thereby pushing the mold after molding and demolding.

[0048] The implementation principle of a foaming device for refrigerator processing according to an embodiment of this application is as follows: First, the third linear actuator 61 is activated to move the arc-shaped shovel plate 62 horizontally. Then, during the movement of the arc-shaped shovel plate 62, foaming liquid is filled between the upper mold 2 and the lower mold 3 through the foaming gun 63. After the mold is formed, the third linear actuator 61 is activated to move the arc-shaped shovel plate 62 and shovel the mold. Then, the second linear actuator 52 is activated to rotate the demolding plate 4. Then, the reset spring 93 moves the push plate 94 and pushes the formed mold. Then, the first linear actuator 32 is activated to move the lower mold 3 downward. The mold follows the lower mold 3 and slides to the next working step. When multiple products need to be produced simultaneously... When molding, multiple cutting mechanisms 8 can be set up. Then, the fifth linear driver 82 is started, and the output shaft of the fifth linear driver 82 drives the cutter 83 to cut the mold. When it is necessary to clean the device, the fourth linear driver 72 is started, and the output shaft of the fourth linear driver 72 drives the cleaning plate 73 to move. Then, the cleaning plate 73 abuts against the stripper plate 4 and cleans the stripper plate 4 during the movement. Then, the third linear driver 61 is started to drive the arc-shaped shovel plate 62 to move. Since the arc-shaped shovel plate 62 abuts against the upper mold 2 and the lower mold 3, it can clean the upper mold 2 and the lower mold 3 to facilitate the next processing. Then, the above working steps are repeated to produce the mold.
