[0002] During the production and maintenance of an injection mold, the cleaning operation of the cooling pipeline system is a key process to ensure the heat conduction efficiency of the mold.

[0003] Since the mold cooling pipelines generally adopt a multi-loop layout, the number of inlet and outlet interfaces of the pipelines is relatively large. In the related art, manually connecting the inlet pipe and the outlet pipe to the corresponding inlet and outlet interfaces of the cooling pipeline takes a long time, and it is easy to cause cleaning blind spots or form an ineffective circulation loop (such as connecting the inlet and outlet ports wrongly), seriously affecting the dirt removal effect.

[0004] Therefore, how to avoid the reduction of the dirt removal effect caused by wrong connection of interfaces is a technical problem that needs to be solved urgently at present.

Detailed implementation manners

[0064] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0065] It has been found through research that when cleaning the cooling pipeline of the injection mold in the prior art, the water inlet pipe and the water outlet pipe are manually connected to the corresponding water inlet and outlet interfaces of the injection mold. On the one hand, due to the complexity of the loop of the cooling pipeline, the number of water inlet and outlet interfaces is excessive, resulting in a high manual labor intensity and a low docking efficiency, thus affecting the cleaning efficiency of the injection mold. On the other hand, manual operation is prone to reversely connect the water inlet and the water outlet or miss some interfaces, causing cleaning blind spots or forming an ineffective circulation loop, seriously affecting the dirt removal effect.

[0066] Based on the above research, embodiments of the present disclosure provide an injection mold 400 cleaning device and a cleaning process. By grouping the cooling pipelines 420 according to the water flow connectivity between interfaces, the method of simultaneously docking the inlet and outlet interfaces 410 in the related art is abandoned. It is only necessary to connect the cleaning head 320 to the joints of the corresponding grouped cooling pipelines 420. At the same time, for the connection of the cleaning head 320, there is no need to adopt the manual docking method. The cleaning head 320 is directly pushed by water pressure to insert it into the joints of the cooling pipelines 420.

[0067] Regarding the defects existing in the above solutions, they are all the results obtained by the inventors through practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article for the above problems should all be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0068] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0069] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0070] Please refer to Figure 1 and Figure 2 , at least one embodiment provides an injection mold 400 cleaning device, including the following structures:

[0071] A cleaning tank 100 for collecting the liquid for cleaning the injection mold 400.

[0072] A suspension assembly 200, which is arranged above the cleaning tank 100 and is used for suspending the injection mold 400.

[0073] The suspension assembly 200 includes a suspension rod 210 and a connecting rod 220. The suspension rod 210 is suspended at the top of the cleaning tank 100, and the injection mold 400 is connected to the suspension rod 210 through the connecting rod 220.

[0074] A cleaning assembly 300, which is arranged in the cleaning tank 100 and is used for cleaning the cooling pipelines 420 of the injection mold 400.

[0075] Please refer to Figures 3 - 5, the cleaning component 300 includes: a cleaning frame 310 which is arranged on the hanging component 200, and the injection mold 400 after being hung is located inside the cleaning frame 310; a plurality of cleaning heads 320 which are arranged on the inner side of the cleaning frame 310 and are oppositely arranged with respect to the interfaces 410 of the cooling pipelines 420 of the injection mold 400.

[0076] Wherein, the cleaning frame 310 is in an inverted "U" shape; the plurality of cleaning heads 320 are divided into two groups, and the two groups of cleaning heads 320 are respectively arranged on the inner sides of the two opposite side pipes of the cleaning frame 310.

[0077] A control module which is configured to group the cooling pipelines 420 according to the water flow connectivity between the interfaces, and control the cleaning heads 320 to communicate with the water inlet pipeline 311 inside the cleaning frame 310 according to the grouping result of the cooling pipelines 420, so as to insert the cleaning heads 320 into the interfaces 410 through water pressure, and further complete the cleaning of the cooling pipelines 420 inside the injection mold 400.

[0078] By grouping the cooling pipelines 420 according to the water flow connectivity between the interfaces, selecting the cleaning heads 320 that need to be docked with the cooling pipelines 420, and completing the docking with the interfaces 410 through the water pressure for supplying water to the cleaning heads 320, while ensuring the docking accuracy, the docking efficiency is improved. At the same time, the method of simultaneously docking the inlet and outlet interfaces 410 in the related art is abandoned, and only by connecting the cleaning heads 320 with the joints of the corresponding grouped cooling pipelines 420 can the cleaning be completed, thereby avoiding the generation of cleaning blind spots and ineffective circulation loops, and further improving the dirt removal effect.

[0079] Please refer to Figure 5 and Figure 6 , the cleaning head 320 includes: a duckbill spray head 321, a telescopic connecting pipe 322 and a solenoid valve 323; after the duckbill spray head 321, the telescopic connecting pipe 322 and the solenoid valve 323 are sequentially communicated, they are communicated with the water inlet pipeline 311 inside the cleaning frame 310; the solenoid valve 323 is electrically connected to the control module.

[0080] It should be noted that the cleaning frame 310 is communicated with an external cleaning pump, and the cleaning liquid is pumped into the cleaning frame 310.

[0081] When the duckbill spray head 321 is communicated with the water inlet pipeline 311 inside the cleaning frame 310, the telescopic connecting pipe 322 is driven by water pressure to drive the duckbill spray head 321 to insert into the interface 410 of the injection mold 400.

[0082] Specifically, please refer to Figures 7 - 9, when the control module controls the solenoid valve 323 to connect the cleaning head 320 with the water inlet pipeline 311 in the cleaning frame 310, liquid enters the cleaning head 320, and the flow direction of the liquid is as shown in Figure 9 F2 in Figure 9 shown, driving the telescopic connecting pipe 322 to extend along the direction shown by F1 in

[0083] shown, so as to drive the duckbill nozzle 321 to insert into the interface 410. The water pressure in the cleaning head 320 continues to increase, causing the duckbill opening of the duckbill nozzle 321 to open, and completing the cleaning of the cooling pipeline 420.

[0084] It should be noted that when the duckbill opening of the duckbill nozzle 321 opens, the outer wall of the duckbill nozzle 321 abuts against the inner wall of the interface 410, thereby reducing the outflow of liquid from the docking place. Figure 7 and Figure 9 refer to

[0085] The telescopic connecting pipe 322 includes: a telescopic pipe 3221 and a baffle 3222; the baffle 3222 is arranged in the telescopic pipe 3221 and is arranged close to the duckbill nozzle 321.

[0086] Among them, the telescopic pipe 3221 is made of an elastic material, such as thermoplastic polyurethane.

[0087] Please refer to Figure 7 , a water outlet 3222a is opened in the middle of the baffle 3222; the diameter of the water outlet 3222a is R1; the pipe diameter of the telescopic pipe 3221 is R2; wherein, the ratio of R1:R2 is between 0.3 - 0.6, and the units of R1 and R2 are mm.

[0088] By limiting the ratio of R1 to R2, it is ensured that the water pressure in the cleaning head 320 meets the extension requirement of the telescopic pipe 3221, and at the same time, it will not cause the water pressure to be too high before the duckbill nozzle 321 is inserted into the interface 410 and directly flush open the duckbill nozzle 321.

[0089] Please continue to refer to Figure 7 , a pair of claw hooks 3211 are oppositely arranged on both sides of the duckbill opening of the duckbill nozzle 321; when the duckbill opening of the duckbill nozzle 321 opens, the two claw hooks 3211 move towards each other, so as to connect with the claw grooves 430 in the interface 410 of the injection mold 400.

[0090] When the duckbill nozzle 321 is inserted into the interface 410, as shown in Figure 10 shown, the water pressure in the cleaning head 320 continues to increase. At this time, the flow direction of the liquid is as shown in Figure 10As shown in F2, open the duckbill opening of the duckbill nozzle 321. At this time, the claw 3211 of the duckbill opening moves towards each other along the Figure 10 direction shown in F1 in the figure, and completes the clamping with the hook groove 430. The schematic diagram of the clamped state is as shown in Figure 11 shown. After the duckbill opening is fully opened, the liquid in the duckbill nozzle 321 enters the cooling pipeline 420 to clean the cooling pipeline 420. The liquid flow direction is as shown in Figure 11 F2 in the figure.

[0091] By setting the claw 3211, the duckbill nozzle 321 is connected to the interface 410, avoiding the detachment of the duckbill nozzle 321 during cleaning. At the same time, there is no need for manual docking of the cleaning head 320, thereby reducing the docking time and improving the cleaning efficiency.

[0092] Please refer to Figure 12 , the control module groups the cooling pipelines 420 according to the connected pipelines, that is: define the interfaces 410 in the injection mold 400, denoted as kn, where kn represents the nth interface 410; sequentially obtain the set of all interfaces 410 within the water flow connectivity between interfaces where each interface 410 is located, denoted as an, where an represents the set of all interfaces 410 connected to the nth interface 410 and includes the nth interface 410 itself; delete the repeated sets in the set of all interfaces 410, retain the first set, and the remaining sets are the grouping results of the cooling pipeline 420 according to the water flow connectivity between interfaces.

[0093] As Figure 12 shown, there are a total of 12 interfaces 410, denoted as k1, k2...k12 respectively. The sets of all interfaces 410 within the water flow connectivity between interfaces where each interface 410 is located are respectively a1 = (k1, k2, k7, k8), a2 = (k1, k2, k7, k8), a3 = (k3, k9)...a12 = (k5, k6, k11, k12).

[0094] Delete the repeated sets in the set of all interfaces 410, retain the first set, that is, a1, a2, a7, and a8 are repeated sets. Delete a2, a7, and a8, and retain the first set, that is, a1.

[0095] As Figure 12 shown, the remaining sets are respectively a1, a3, a4, and a5.

[0096] Specifically, through the manual input method, all interfaces 410 within the water flow connectivity between interfaces where each interface 410 is located can be input into the control module to facilitate the control module to control the subsequent cleaning. For example, manually send the corresponding data to the control module through the touch display screen.

[0097] When manually distinguishing the water flow connectivity between interfaces, each interface 410 can be filled with water in sequence. By observing the interface 410 from which the liquid flows out manually at this time, all the interfaces 410 regarding the water flow connectivity between interfaces where each interface 410 is located can be obtained.

[0098] Among them, the control module controls the cleaning head 320 to communicate with the water inlet pipeline 311 in the cleaning frame 310 according to the grouping result of the cooling pipeline 420, that is: select one interface 410 in the set of each group as the drainage port, and connect the remaining interfaces 410 in the set to the cleaning head 320.

[0099] Specifically, taking Figure 12 as an example, Figure 12 There are a total of 4 grouping results, which are a1 = (k1, k2, k7, k8), a3 = (k3, k9), a4 = (k4, k10), and a5 = (k5, k6, k11, k12) respectively. The last interface 410 in the set of each group is used as the drainage port, that is, k8, k9, k10, and k12 are used as the drainage ports, and the remaining interfaces 410 are all connected to the corresponding duckbill nozzle 321.

[0100] Please refer to Figure 13 , at least one embodiment also provides a cleaning process applied to the cleaning equipment of the injection mold 400 as described above. The cleaning process includes:

[0101] Step S1, suspend the injection mold 400 in the cleaning tank 100 through the suspension assembly 200.

[0102] Specifically, manually suspend the injection mold 400 in the cleaning tank 100.

[0103] Step S2, group the cooling pipelines 420 of the injection mold 400 according to the water flow connectivity between interfaces.

[0104] Specifically, step S2 includes:

[0105] Step S21, define the interfaces 410 of the cooling pipelines 420 in the injection mold 400, denoted as kn, and kn represents the nth interface 410.

[0106] Specifically, as Figure 12 shown, there are a total of 12 interfaces 410, which are respectively denoted as k1, k2...k12.

[0107] Step S22, sequentially obtain the set of all interfaces 410 within the water flow connectivity between interfaces where each interface 410 is located, denoted as an, and an represents the set of all interfaces 410 connected to the nth interface 410, and includes the nth interface 410 itself.

[0108] Specifically, as Figure 12 shown, the sets of all the interfaces 410 within the water flow connectivity between interfaces where each interface 410 is located are respectively a1 = (k1, k2, k7, k8), a2 = (k1, k2, k7, k8), a3 = (k3, k9)... a12 = (k5, k6, k11, k12).

[0109] Step S23: Delete the duplicate sets in the sets of all the interfaces 410, retain the first set, and the remaining sets are the grouping results of the cooling pipeline 420 according to the water flow connectivity between interfaces.

[0110] Specifically, as Figure 12 shown, a1, a2, a7, and a8 are duplicate sets. Delete a2, a7, and a8, retain the first set, that is, a1, and the remaining sets are respectively a1, a3, a4, and a5.

[0111] Step S3: The control module controls the cleaning head 320 to be connected to the water inlet pipeline 311 within the cleaning frame 310 according to the grouping result.

[0112] Step S4: Clean the cooling pipeline 420 in the injection mold 400.

[0113] In summary, the embodiments of the present invention provide an injection mold 400 cleaning device and a cleaning process. The injection mold 400 cleaning device includes: a cleaning tank 100; a suspension assembly 200, which is arranged above the cleaning tank 100 and is used for suspending the injection mold 400; a cleaning assembly 300, which is arranged in the cleaning tank 100 and is used for cleaning the cooling pipeline 420 of the injection mold 400. Among them, the cleaning assembly 300 includes: a cleaning frame 310, which is arranged on the suspension assembly 200, and the suspended injection mold 400 is located inside the cleaning frame 310; a plurality of cleaning heads 320, which are arranged on the inner side of the cleaning frame 310 and are arranged opposite to the interfaces 410 of the cooling pipeline 420 of the injection mold 400; a control module, which is configured to group the cooling pipelines 420 according to the water flow connectivity between the interfaces, and control the cleaning heads 320 to communicate with the water inlet pipeline 311 in the cleaning frame 310 according to the grouping result of the cooling pipelines 420, so as to insert the cleaning heads 320 into the interfaces 410 of the cooling pipeline 420 through water pressure, and then complete the cleaning of the cooling pipeline 420 in the injection mold 400. By grouping the cooling pipelines 420 according to the water flow connectivity between the interfaces, selecting the cleaning heads 320 that need to be docked with the cooling pipeline 420, and completing the docking with the interfaces of the cooling pipeline 420 through the water pressure for supplying water to the cleaning heads 320, while ensuring the docking accuracy, the docking efficiency is improved. At the same time, the method of simultaneously docking the inlet and outlet interfaces 410 in the related technology is abandoned. Only by connecting the cleaning heads 320 to the joints of the corresponding grouped cooling pipelines 420 can the cleaning be completed, thereby avoiding the generation of cleaning blind spots and ineffective circulation loops, and further improving the dirt removal effect.
