Description

Technical Field

[0001] This invention relates to the technical field of power supply box manufacturing equipment, and in particular to a power supply box and its discharge outlet mechanism, manufacturing equipment, and manufacturing method. Background Technology

[0002] Before the power supply box semi-finished product is demolded, the sprue is stuck in the gap of the injection molding mold. Traditional injection molding molds use two methods to remove the sprue:

[0003] Firstly, manually removing the sprue requires stopping the injection molding machine. Then, the sprue and the one-piece molded power box semi-finished product are manually removed, and the sprue is then manually separated from the power box semi-finished product. Therefore, manually removing the sprue has the following problems: 1) It requires stopping the machine, delaying the product's production schedule, thus reducing the production efficiency of the power box; 2) Manually removing the sprue is inefficient, further reducing the production efficiency of the power box; 3) It requires significant labor intensity.

[0004] Secondly, while blowing off sprue marks can improve the efficiency of sprue removal, it has the following problems: 1) It is difficult to ensure the sprue removal rate. If some sprue marks are not blown off, that is, if some sprue marks remain stuck in the gaps of the injection mold, they are more likely to fall into the ejector. When the ejector retracts, it will carry the sprue to the clutch mold, thereby damaging the injection mold. At this time, the machine needs to be stopped for maintenance, which delays the production progress and reduces the production efficiency of the power box; 2) The blown-off sprue marks fall in a messy manner and need to be collected manually every time, which increases the labor intensity of the workers. Otherwise, it will affect the operation of the injection mold and even affect the manufacturing precision of the power box. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power box with high production efficiency, low manual labor intensity and high manufacturing precision, as well as its material discharge outlet mechanism, manufacturing equipment and manufacturing method.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A sprue removal mechanism for a power supply box is used to unload the power supply box from an injection molding mold and simultaneously remove the sprue from the injection molding mold; the power supply box unloading and sprue removal mechanism includes:

[0008] Fixture drive mechanism;

[0009] A clamping mechanism includes a positioning plate, a clamping assembly, and a suction cup assembly. The positioning plate is mounted on the power output end of the clamping drive mechanism, causing the clamping drive mechanism to drive the positioning plate to move. The positioning plate has a clamping mounting position and a suction cup mounting position. The clamping assembly is used to grip and fix the sprue when the positioning plate moves to a position corresponding to the injection molding mold. The suction cup assembly is used to attract the power supply box when the positioning plate moves to a position corresponding to the injection molding mold. The clamping assembly is also used to release the sprue when the positioning plate moves to the unloading area, and the suction cup assembly is also used to release the power supply box when the positioning plate moves to the unloading area.

[0010] Compared with the prior art, the present invention has at least the following advantages:

[0011] 1) The sprue removal mechanism of the power box of the present invention uses a clamping assembly to remove the sprue by gripping. Compared with the traditional method of removing the sprue by blowing air, the clamping assembly of this application can act more precisely on the sprue, so that the sprue can be quickly and reliably removed from the injection molding mold. This avoids the problem of the injection molding mold needing to be stopped for maintenance due to the sprue remaining in the gap of the injection molding mold. As a result, the injection molding mold can operate continuously, thereby ensuring the production efficiency of the power box and ensuring the service life of the injection molding mold.

[0012] 2) The sprue removal mechanism for the power box of the present invention automates the process by having the sprue gripped by the clamping assembly and released in the unloading area. This mechanical automation collects the sprue in the unloading area, avoiding the need for manual removal and collection, thus reducing labor intensity. It also prevents the sprue from falling between the left and right molds of the injection molding die, preventing them from being unable to abut. This ensures reliable contact between the left and right molds during injection molding, ensuring they reliably form the injection cavity and guaranteeing the manufacturing precision of the power boxes in the next production run. It also avoids the need to stop the machine to collect sprues that have fallen between the left and right molds, allowing the injection molding die to operate continuously. Thus, through the combined action of the clamping assembly and the injection molding die, the batch molding, sprue removal, and unloading of power boxes are automated, further ensuring the production efficiency of the power boxes.

[0013] 3) The power box unloading and desprue mechanism of the present invention uses a clamping drive mechanism to drive the positioning plate, clamping assembly and suction cup assembly to move synchronously. The positioning plate has a clamping mounting position and a suction cup mounting position, that is, the positioning plate is respectively provided with the clamping assembly and the suction cup assembly. Therefore, the positioning plate simultaneously drives the clamping assembly and the suction cup assembly to move, so that the sprue and the power box are taken out of the injection molding mold at the same time, which improves the efficiency of unloading and desprue removal, realizes reliable automatic unloading and desprue removal operation, and further ensures the production efficiency of the power box.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Please refer to the following: Figures 1 to 8 This application provides a power box unloading and sprue removal mechanism 1; and / or, for unloading a power box 3 injection molded by an injection molding mold 2; and / or, simultaneously capable of removing the sprue 4 on the injection molding mold 2; and / or, the power box unloading and sprue removal mechanism 1 includes a clamping drive mechanism 10 and a clamping mechanism 20; and / or, the clamping mechanism 20 includes a positioning plate 100, a clamping assembly 200 and a suction cup assembly 300, the positioning plate 100 being mounted on the power output end of the clamping drive mechanism 10; and / or, causing the clamping drive mechanism 10 to drive the positioning plate 100 to move; And / or, the positioning plate 100 is provided with a clamp mounting position 101 and a suction cup mounting position 102; and / or, the clamp assembly 200 is used to grip and fix the sprue 4 when the positioning plate 100 moves to the position corresponding to the injection molding mold 2; and / or, the suction cup assembly 300 is used to adsorb the power supply box 3 when the positioning plate 100 moves to the position corresponding to the injection molding mold 2; and / or, the clamp assembly 200 is also used to release the sprue 4 when the positioning plate 100 moves to the unloading area; and / or, the suction cup assembly 300 is also used to release the power supply box 3 when the positioning plate 100 moves to the unloading area.

[0039] The aforementioned power box unloading and sprue removal mechanism 1 uses a clamping assembly 200 to remove the sprue 4 by gripping. Compared to the traditional method of removing the sprue 4 by blowing air, the clamping assembly 200 of this application can act more precisely on the sprue 4, enabling the sprue 4 to be quickly and reliably removed from the injection molding mold 2. This avoids the problem of the sprue 4 being stuck in the gaps of the injection molding mold 2, which would require downtime maintenance of the injection molding mold 2. As a result, the injection molding mold 2 can operate continuously, thereby ensuring the production efficiency of the power box 3 and ensuring the service life of the injection molding mold 2. Furthermore, the sprue 4 is gripped by the clamping assembly 200 and then released, meaning that the sprue 4 is collected in the unloading area through mechanical automation. This avoids the problem of manually removing and collecting the sprue 4, thereby reducing the intensity of manual labor. At the same time, it prevents the sprue 4 from falling between the left mold 30 and the right mold 40 of the injection molding mold 2, thus preventing the left mold 30 and the right mold 40 from being stuck between them and failing to abut. This ensures that the left mold 30 and the right mold 40 abut reliably during injection molding. This ensures that the left mold 30 and the right mold 40 reliably form the injection cavity 201, thereby ensuring the manufacturing precision of the power box 3 in the next production run. It also avoids the need to stop the machine to collect the sprue 4 that has fallen between the left mold 30 and the right mold 4, allowing the injection molding mold 2 to operate continuously. Thus, through the combined action of the fixture assembly 200 and the injection molding mold 2, the batch molding of power boxes 3, the removal of sprue 4, and the unloading of power boxes 3 are automated, thereby further ensuring the production efficiency of power boxes 3. In addition, the clamping drive mechanism 10 drives the positioning plate 100, clamping assembly 200 and suction cup assembly 300 to move synchronously. The positioning plate 100 has a clamping mounting position 101 and a suction cup mounting position 102. That is, the positioning plate 100 is respectively equipped with clamping assembly 200 and suction cup assembly 300. Therefore, the positioning plate 100 drives the clamping assembly 200 and suction cup assembly 300 to move at the same time, so that the sprue 4 and the power box 3 are taken out of the injection molding mold 2 at the same time, which improves the efficiency of material feeding and sprue removal 4, realizes reliable automatic material feeding and sprue removal 4 operation, and further ensures the production efficiency of power box 3.

[0040] It should be noted that "unloading" refers to the suction cup assembly 300 adsorbing the power box 3 until the power box 3 reaches the unloading area, at which point the suction cup assembly 300 releases the power box 3, so that the power box 3 is collected in the unloading area; "sprue 4" refers to the clamp 210 assembly gripping the sprue 4 until the sprue 4 reaches the unloading area, at which point the clamp 210 assembly releases the sprue 4, so that the sprue 4 is collected in the unloading area.

[0041] In one embodiment, the fixture assembly includes a fixture drive assembly and a fixture. The power output end of the fixture drive assembly is connected to the fixture, and the fixture drive assembly is used to drive the fixture to open or clamp. It can be understood that the fixture drive assembly is used to drive the fixture to open or clamp. When the fixture drive assembly drives the fixture to clamp the sprue, it cooperates with the ejection mechanism of the injection molding mold to disconnect the sprue from the power box and clamps the sprue to move it to the unloading area. The fixture drive assembly is also used to drive the fixture to open, so that when the sprue moves to the unloading area, the sprue is released and collected in the unloading area, thus ensuring the effectiveness of sprue removal and reducing manual labor intensity.

[0042] In one embodiment, the clamping drive assembly is a cylinder. It is understood that the cylinder controls the clamping mechanism to open or close.

[0043] Please refer to the following: Figures 9-10 In one embodiment, there are multiple suction cup assemblies 300 and clamping assemblies 200. Multiple suction cup assemblies 300 are spaced apart on the positioning plate 100. Each suction cup assembly 300 includes a first suction cup assembly 310 and a second suction cup assembly 320 spaced apart. A clamping assembly 200 is provided between the first suction cup assembly 310 and the second suction cup assembly 320 of each suction cup assembly 300. It can be understood that multiple suction cup assemblies 300 can simultaneously adsorb multiple power supply boxes 3, thereby improving the unloading efficiency, and multiple clamping assemblies 200 can simultaneously grasp multiple sprue outlets 4, thereby improving the sprue outlet 4 removal efficiency, and thus improving the production efficiency of the power supply boxes 3.

[0044] Please see Figure 19 Furthermore, in one embodiment, a sprue 4 is sandwiched between every two power box 3 semi-finished products. Therefore, a clamping assembly 200 is provided between the first suction cup assembly 310 and the second suction cup assembly 320, which further improves the material feeding efficiency and the efficiency of removing the sprue 4, thereby improving the production efficiency of the power box 3.

[0045] Please see Figure 11 and Figure 16In one embodiment, each suction cup assembly 300 includes a first suction cup assembly 310, a first suction tube body 312, and a first suction cup body 313. One end of the first fixing member 311 is fixed to the positioning plate 100, and the first suction tube body 312 is sleeved on the other end of the first fixing member 311. The first suction tube body 312 forms a first suction channel 301 and a first suction cup mounting seat 312a. The first suction cup mounting seat 312a forms a suction hole 303 communicating with the first suction channel 301. The first suction cup body 313 is mounted on the first suction cup mounting seat 312a. It is understood that when the first suction cup body 313 moves to the position corresponding to the injection molding mold 2, the first suction tube body 312 uses air suction to adsorb the power box 3 onto the first suction cup body 313. When the first suction cup body 313 moves to the unloading area, the first suction tube body 312 uses air blowing to release the power box 3 from the first suction cup body 313, thereby completing the unloading and collection of the power box 3.

[0046] Please see Figure 14 In one embodiment, the first fixing member 311 includes a first fixing post 311a, a first limiting head 311b, and a first locking nut 311c. The first limiting head 311b and the first locking nut 311c are both sleeved on the first fixing post 311a. The first fixing post 311a is installed on the positioning plate 100. The first limiting head 311b and the first locking nut 311c are located on both sides of the positioning plate 100. The first fixing post 311a has a first threaded portion. The first locking nut 311c is sleeved on the first threaded portion and threaded to the first fixing post 311a. The first suction tube body 312 is sleeved on the first fixing post 311a. It is understood that the first limiting head 311b and the first locking nut 311c are located on both sides of the positioning plate 100, positioning the first fixing post 311a on the positioning plate 100, thereby positioning the first suction tube body 312 and the first suction cup body 313 on the positioning plate 100, thus making the alignment of the first suction cup body 313 with the power box 3 more accurate, thereby ensuring the adsorption effect of the first suction cup body 313 on the power box 3, and thus allowing the power box 3 to be completely sent to the unloading area; in addition, the first fixing post 311 The first fixing post 311a is installed on the positioning plate 100 and the first locking nut 311c is screwed to the first fixing post 311a. That is, the first fixing post 311a is detachable from the positioning plate 100. Therefore, when the suction cup assembly 300 is not compatible with the power box 3, the suction cup assembly 300 can be replaced to ensure the compatibility between the suction cup assembly 300 and the power box 3. Similarly, when the suction cup assembly 300 is damaged, it can be replaced to ensure the suction effect of the suction cup assembly 300 on the power box 3.

[0047] Please see Figure 12 and Figure 16In one embodiment, the second suction cup assembly 320 of each suction cup assembly 300 includes a second fixing member 321, a second suction tube body 322 and a second suction cup body 323. One end of the second fixing member 321 is fixed to the positioning plate 100, the second suction tube body 322 is sleeved on the other end of the second fixing member 321, the second suction tube body 322 forms a second suction channel and a second suction cup mounting seat, the second suction cup mounting seat forms a suction hole 303 communicating with the second suction channel, and the second suction cup body 323 is mounted on the second suction cup mounting seat.

[0048] Furthermore, the second fixing component includes a second fixing post, a second limiting head, and a second locking nut. The second limiting head and the second locking nut are both sleeved on the second fixing post. The second fixing post is installed through the positioning plate. The second limiting head and the second locking nut are located on both sides of the positioning plate. The second fixing post has a second threaded connection portion. The second locking nut is sleeved on the second threaded connection portion and threaded to the second fixing post. The second suction tube body is sleeved on the second fixing post.

[0049] Please refer to the following: Figures 1 to 8 This application also provides a power supply box manufacturing apparatus 1A, used to simultaneously manufacture the lid and body of the power supply box 3. The aforementioned power supply box manufacturing apparatus 1A includes a power supply box unloading and sprue removal mechanism 1 and an injection molding die 2 as described in any of the above embodiments. Further, the power supply box unloading and sprue removal mechanism 1 is used to unload the power supply box 3 injection-molded by the injection molding die 2, and can simultaneously remove the sprue 4 from the injection molding die 2; the power supply box unloading and sprue removal mechanism 1 includes a clamping drive mechanism 10 and a clamping mechanism 20. The clamping mechanism 20 includes a positioning plate 100, a clamping assembly 200, and a suction cup assembly 300. The positioning plate 100 is mounted on the power output end of the clamping drive mechanism 10, causing the clamping drive mechanism 10 to drive the positioning plate 100 to move. The positioning plate 100 has a clamp mounting position 101 and a suction cup mounting position 102. The clamp assembly 200 is used to grip and fix the sprue 4 when the positioning plate 100 moves to the position corresponding to the injection molding mold 2. The suction cup assembly 300 is used to adsorb the power box 3 when the positioning plate 100 moves to the position corresponding to the injection molding mold 2. The clamp assembly 200 is also used to release the sprue 4 when the positioning plate 100 moves to the unloading area. The suction cup assembly 300 is also used to release the power box 3 when the positioning plate 100 moves to the unloading area.

[0050] In the aforementioned power box manufacturing equipment 1A, after the power box 3 semi-finished product is injection molded by the injection molding mold 2, the power box unloading and sprue removal mechanism 1 cooperates with the injection molding mold 2 to separate the power box 3 and the sprue 4 from the injection molding mold 2 and move them to the unloading area, where the power box 3 and the sprue 4 are collected sequentially. Furthermore, the aforementioned power box unloading and sprue removal mechanism 1, with its clamping assembly 200, removes the sprue 4 by gripping. Compared to the traditional method of removing the sprue 4 by blowing air, the clamping assembly 200 of this application can act more precisely on the sprue 4, enabling the sprue 4 to be quickly and reliably removed from the injection molding mold 2. This avoids the problem of the sprue 4 remaining in the gaps of the injection molding mold 2, which would require downtime maintenance of the injection molding mold 2. This allows the injection molding mold 2 to operate continuously, thereby ensuring the production efficiency of the power box 3 and ensuring the service life of the injection molding mold 2. Furthermore, the sprue 4 is gripped by the clamping assembly 200 and then released, meaning that the sprue 4 is collected in the unloading area through mechanical automation. This avoids the problem of manually removing and collecting the sprue 4, thereby reducing the intensity of manual labor. At the same time, it prevents the sprue 4 from falling between the left mold 30 and the right mold 40 of the injection molding mold 2, thus preventing the left mold 30 and the right mold 40 from being stuck between them and failing to abut. This ensures that the left mold 30 and the right mold 40 abut reliably during injection molding. This ensures that the left mold 30 and the right mold 40 reliably form the injection cavity 201, thereby ensuring the manufacturing precision of the power box 3 in the next production run. It also avoids the need to stop the machine to collect the sprue 4 that has fallen between the left mold 30 and the right mold 4, allowing the injection molding mold 2 to operate continuously. Thus, through the combined action of the fixture assembly 200 and the injection molding mold 2, the batch molding of power boxes 3, the removal of sprue 4, and the unloading of power boxes 3 are automated, thereby further ensuring the production efficiency of power boxes 3. In addition, the clamping drive mechanism 10 drives the positioning plate 100, clamping assembly 200 and suction cup assembly 300 to move synchronously. The positioning plate 100 has a clamping mounting position 101 and a suction cup mounting position 102. That is, the positioning plate 100 is respectively equipped with clamping assembly 200 and suction cup assembly 300. Therefore, the positioning plate 100 drives the clamping assembly 200 and suction cup assembly 300 to move at the same time, so that the sprue 4 and the power box 3 are taken out of the injection molding mold 2 at the same time, which improves the efficiency of material feeding and sprue removal 4, realizes reliable automatic material feeding and sprue removal 4 operation, and further ensures the production efficiency of power box 3.

[0051] like Figure 18As shown, the injection molding die 2 further includes a left mold 30 and a right mold 40, which are arranged opposite to each other. The left mold 30 is used to move relative to the right mold 40 during molding to form multiple power box lids and multiple power box bodies, thereby enabling the injection molding die 2 to form multiple power boxes 3. The injection cavity 201 includes a box body forming cavity and a box lid forming cavity. In this embodiment, there are M box body forming cavities and M box lid forming cavities, so as to jointly form M box lids and M box bodies, thereby manufacturing M power boxes 3, where M is an integer greater than or equal to 1.

[0052] like Figure 18 As shown, specifically, the left mold 30 has M lid forming bosses, and the right mold 40 has M lid forming grooves. The M lid forming bosses and M lid forming grooves are arranged in a one-to-one correspondence to form M lid forming cavities when the left mold 30 and right mold 40 are closed. Similarly, the left mold 30 has M box body forming bosses, and the right mold 40 has M box body forming grooves. These same bosses and grooves are also arranged in a one-to-one correspondence to form M box body forming cavities when the left mold 30 and right mold 40 are closed. It should be noted that the injection molding mold 2 can mold M lids and M boxes in one operation. The M lids and M boxes are then manually snapped together to complete the manufacturing of M power boxes 3.

[0053] This application also provides a power supply box, which is manufactured using the power supply box manufacturing equipment described in the above embodiments.

[0054] like Figures 1 to 8 As shown, this application also provides a method for manufacturing a power supply box 3. The above-described method for manufacturing the power supply box 3 is used to manufacture the power supply box 3 described in any of the above embodiments, and the method includes all or part of the following steps:

[0055] S101. Injection molding is performed through injection molding mold 2 to form a power box 3 semi-finished product and sprue 4.

[0056] In this embodiment, the left mold 30 and the right mold 40 of the injection molding mold 2 are controlled to abut against each other to form an injection cavity 201. The injection cavity 201 is used for injection molding of the power box 3 semi-finished product and the sprue 4. The molded power box 3 semi-finished product is detachably connected to the side wall of the left mold 30, the sprue 4 is inserted into the hole of the left mold 30, and the molded power box 3 semi-finished products are connected to each other through the sprue 4.

[0057] S103, The positioning plate 100 of the clamping mechanism 20 is moved above the injection molding mold 2 by the clamping drive mechanism 10.

[0058] In this embodiment, the positioning plate 100 moves above the injection molding mold 2.

[0059] S105, control the separation of the left mold 30 and the right mold 40 of the injection molding mold 2.

[0060] In this embodiment, the left mold 30 and the right mold 40 of the injection molding mold 2 are separated until the space between the left mold 30 and the right mold 40 is sufficient for the clamping mechanism 20 to move; at this time, the power box 3 semi-finished product is exposed on the side wall of the left mold 30, and the sprue 4 is partially exposed on the side wall of the left mold 30.

[0061] S107. The positioning plate 100 of the clamping mechanism 20 is moved to the position corresponding to the injection molding mold 2 by the clamping drive mechanism 10.

[0062] In this embodiment, the clamp driving mechanism 10 drives the positioning plate 100 to move, thereby driving the clamp assembly 200 and the suction cup assembly 300 to move until the clamp assembly 200 moves to the position corresponding to the sprue 4 and the suction cup assembly 300 moves to the position corresponding to the power box 3 semi-finished product.

[0063] S109, the ejection mechanism 400 of the left mold 30 of the injection molding mold 2 ejects the power box 3 semi-finished product to the first position 401, so that the sprue 4 is partially exposed in the injection molding mold 2.

[0064] In this embodiment, when the power box 3 semi-finished product and the sprue 4 are formed, the sprue 4 is completely set in the gap of the injection molding mold 2, making it difficult for the clamping assembly 200 to grasp the sprue 4. In order for the clamping assembly 210 to grasp the sprue 4 better, the ejection mechanism 400 is first controlled to eject the power box 3 semi-finished product, so that the power box 3 semi-finished product moves towards the right mold 40. Since the power box 3 semi-finished product and the sprue 4 are integrally formed, the sprue 4 also moves towards the right mold 40, thereby making the sprue 4 at least partially exposed in the injection molding mold 2. This improves the convenience of the clamping assembly 200 in grasping the sprue 4 in the subsequent S111 step, and ensures the firmness of the clamping assembly 200 in grasping the sprue 4 in the subsequent S111 step.

[0065] S111, the control clamp assembly 200 grips and fixes the sprue 4, so that the sprue 4 is positioned on the injection molding mold 2.

[0066] In this embodiment, in step S109, the sprue 4 is partially exposed on the injection molding mold 2, which facilitates the gripping of the sprue 4 by the clamping assembly 200 in this step. This improves the ease of gripping the sprue 4 by the clamping assembly 200, thereby increasing the production efficiency of the power box 3. It also ensures the firmness of the gripping of the sprue 4 by the clamping assembly 200, avoiding the problem of the sprue 4 falling off due to insufficient gripping. This also avoids the problem of the fallen sprue 4 getting stuck between the left mold 30 and the right mold 40, thus avoiding the need to stop the machine to collect it. The problem of sprue 4 falling between the left mold 30 and the right mold 40 is solved, allowing the injection molding mold 2 to operate continuously, thereby further ensuring the production efficiency of the power box 3; and the problem of sprue 4 falling between the left mold 30 and the right mold 40 being unable to abut is avoided, that is, the left mold 30 and the right mold 40 abut during injection molding is ensured, thereby ensuring that the left mold 30 and the right mold 40 form the injection cavity 201, thereby ensuring the manufacturing accuracy of the power box 3 in the next round of production.

[0067] Furthermore, at this point, the sprue 4 and the power box 3 semi-finished product are connected, and the clamp assembly 200 grips and fixes the sprue 4 so that in the subsequent step S113, the sprue 4 and the power box 3 can be separated by moving the power box 3 semi-finished product.

[0068] S113, the ejection mechanism 400 of the left mold 30 of the injection molding mold 2 ejects the power box 3 to the second position 402, so that the sprue 4 is disconnected from the power box 3.

[0069] In this embodiment, the sprue 4 is fixed by the clamp assembly 200, while the power box 3 is pushed out by the push-out mechanism 400 of the left mold 30, so that the sprue 4 and the power box 3 are disconnected, so that the subsequent unloading operation and the sprue 4 removal operation can be performed, reducing the intensity of manual labor; at the same time, the power box 3 is pushed out by the push-out mechanism 400 of the left mold 30, so that the power box 3 moves to abut against the suction cup assembly 300, so that in the subsequent S115 step, the suction cup assembly 300 can better adhere to the power box 3.

[0070] S115, the suction cup assembly 300 is attached to the power supply box 3.

[0071] In this embodiment, since the power supply box 3 and the suction cup assembly 300 have already come into contact in step S113, in this step, the suction cup assembly 300 is made to adhere to the power supply box 3 by evacuating the suction cup assembly 300.

[0072] S117. Control the clamp drive mechanism 10 to move to the unloading area, so that the clamp assembly 200 grips the sprue 4 away from the injection molding mold 2, and at the same time, the suction cup assembly 300 adsorbs the power box 3 away from the injection molding mold 2.

[0073] In this embodiment, the clamping assembly 200 grips the sprue 4 away from the injection molding mold 2, while the suction cup assembly 300 adsorbs the power box 3 away from the injection molding mold 2. This allows the suction cup assembly 300 to carry the sprue 4 and the clamping assembly 200 to carry the power box 3 away from the injection molding mold 2 and move them to the unloading area. This reduces the time for unloading and removing the sprue 4, thereby improving the manufacturing efficiency of the power box 3.

[0074] S119, Control suction cup assembly 300 to release power box 3.

[0075] In this embodiment, the suction cup assembly 300 is controlled to release the power box 3 so that the power box 3 and the water inlet 4 can be placed separately, reducing the intensity of manual labor.

[0076] S121, Control clamp assembly 200 releases water outlet 4.

[0077] In this embodiment, the control clamp assembly 200 releases the water inlet 4 so that the power box 3 and the water inlet 4 can be placed separately, reducing the intensity of manual labor.

[0078] In the manufacturing method of the power box 3 described above, the clamping assembly 200 removes the sprue 4 by gripping. Compared with the traditional method of removing the sprue 4 by blowing air, the clamping assembly 200 of this application can act more precisely on the sprue 4, so that the sprue 4 can be quickly and reliably removed from the injection molding mold 2. This avoids the problem of the sprue 4 being stuck in the gap of the injection molding mold 2, which would require the injection molding mold 2 to be stopped for maintenance. As a result, the injection molding mold 2 can operate continuously, thereby ensuring the production efficiency of the power box 3 and ensuring the service life of the injection molding mold 2. Furthermore, the sprue 4 is gripped by the clamping assembly 200 and then released, meaning that the sprue 4 is collected in the unloading area through mechanical automation. This avoids the problem of manually removing and collecting the sprue 4, thereby reducing the intensity of manual labor. At the same time, it prevents the sprue 4 from falling between the left mold 30 and the right mold 40 of the injection molding mold 2, thus preventing the left mold 30 and the right mold 40 from being stuck between them and failing to abut. This ensures that the left mold 30 and the right mold 40 abut reliably during injection molding. This ensures that the left mold 30 and the right mold 40 reliably form the injection cavity 201, thereby ensuring the manufacturing precision of the power box 3 in the next production run. It also avoids the need to stop the machine to collect the sprue 4 that has fallen between the left mold 30 and the right mold 4, allowing the injection molding mold 2 to operate continuously. Thus, through the combined action of the fixture assembly 200 and the injection molding mold 2, the batch molding of power boxes 3, the removal of sprue 4, and the unloading of power boxes 3 are automated, thereby further ensuring the production efficiency of power boxes 3. In addition, the clamping drive mechanism 10 drives the positioning plate 100, clamping assembly 200 and suction cup assembly 300 to move synchronously. The positioning plate 100 has a clamping mounting position 101 and a suction cup mounting position 102. That is, the positioning plate 100 is respectively equipped with clamping assembly 200 and suction cup assembly 300. Therefore, the positioning plate 100 drives the clamping assembly 200 and suction cup assembly 300 to move at the same time, so that the sprue 4 and the power box 3 are taken out of the injection molding mold 2 at the same time, which improves the efficiency of material feeding and sprue removal 4, realizes reliable automatic material feeding and sprue removal 4 operation, and further ensures the production efficiency of power box 3.

[0079] In one embodiment, the clamp includes a clamp body and two clamp arms. Clamp arm mounting positions are provided on both sides of the clamp body. Each clamp arm is mounted in a corresponding clamp arm mounting position, and the two clamp arms are rotatably connected to both sides of the clamp body.

[0080] Furthermore, each clamp arm has multiple arc-shaped grooves on the side closest to the adjacent clamp wall.

[0081] Furthermore, the diameter of one of the arc-shaped grooves in each clamp arm is larger than the diameter of the other arc-shaped grooves.

[0082] In one embodiment, clamp arm receiving grooves are provided on both sides of the clamp body. It can be understood that the clamp arm receiving grooves protect the clamp arms, and the clamp arms rotate along the inner peripheral wall of the clamp arm receiving grooves, thus serving as guides.

[0083] In one embodiment, a spring is arranged around the first fixing post, and the spring is connected to the first suction cup body.

[0084] In one embodiment, a spring is arranged around the second fixing post, and the spring is connected to the second suction cup body.

[0085] In one embodiment, the clamping drive mechanism includes an x-axis clamping drive mechanism, a y-axis clamping drive mechanism, and a z-axis clamping drive mechanism. It can be understood that the x-axis clamping drive mechanism, the y-axis clamping drive mechanism, and the z-axis clamping drive mechanism respectively control the movement of the clamping mechanism in three different directions.

[0086] In one embodiment, the fixture drive mechanism includes a rotating assembly connected to the rotating end of the positioning plate, the rotating assembly causing the positioning plate to rotate to a corresponding angle in the corresponding process.

[0087] In one embodiment, the rotating end of the positioning plate is electrically connected to the rotating assembly.

[0088] In one embodiment, the left mold of the injection molding die has a power box injection molding seat on its side wall. When the power box injection molding seat abuts against the right mold, an injection cavity is formed. It can be understood that the injection-molded power box semi-finished product is fitted onto the power box injection molding seat.

[0089] In one embodiment, the fixture has a positioning hole, and the fixture assembly also includes a fixture positioning element, which is set to correspond to the positioning hole, thereby improving the installation accuracy of the fixture.

[0090] Compared with the prior art, the present invention has at least the following advantages:

[0091] 1) The sprue removal mechanism 1 of the power box of the present invention uses a clamping assembly 200 to remove the sprue 4 by gripping. Compared with the traditional method of removing the sprue 4 by blowing air, the clamping assembly 200 of this application can act on the sprue 4 more accurately, so that the sprue 4 can be quickly and reliably removed from the injection molding mold 2. This avoids the problem of the sprue 4 being stuck in the gap of the injection molding mold 2, which would require the injection molding mold 2 to be stopped for maintenance. This allows the injection molding mold 2 to operate continuously, thereby ensuring the production efficiency of the power box 3 and ensuring the service life of the injection molding mold 2.

[0092] 2) In the power box unloading and sprue removal mechanism 1 of the present invention, the sprue 4 is gripped by the clamping assembly 200 and then released, that is, the sprue 4 is collected in the unloading area by mechanical automation, avoiding the problem of manually removing and collecting the sprue 4, thereby reducing the intensity of manual labor. At the same time, it prevents the sprue 4 from falling between the left mold 30 and the right mold 40 of the injection molding mold 2, that is, it avoids the problem of the left mold 30 and the right mold 40 not being able to abut each other when the sprue 4 falls between them, thereby ensuring that the left mold 30 and the right mold 40 are properly aligned during injection molding. The mold 40 reliably abuts, thereby ensuring that the left mold 30 and the right mold 40 reliably form the injection cavity 201, thus ensuring the manufacturing accuracy of the power box 3 in the next production run. It also avoids the problem of needing to stop the machine to collect the sprue 4 that has fallen between the left mold 30 and the right mold 40, allowing the injection molding mold 2 to operate continuously. In this way, through the joint action of the fixture assembly 200 and the injection molding mold 2, the batch molding of power boxes 3, the removal of sprue 4 and the unloading of power boxes 3 are automated, thereby further ensuring the production efficiency of power boxes 3.

[0093] 3) The power box unloading and desprue mechanism 1 of the present invention, the clamp driving mechanism 10 drives the positioning plate 100, the clamp assembly 200 and the suction cup assembly 300 to move synchronously. The positioning plate 100 has a clamp mounting position 101 and a suction cup mounting position 102, that is, the positioning plate 100 is respectively provided with the clamp assembly 200 and the suction cup assembly 300. Therefore, the positioning plate 100 simultaneously drives the clamp assembly 200 and the suction cup assembly 300 to move, so that the sprue 4 and the power box 3 are simultaneously taken out from the injection molding mold 2, which improves the efficiency of unloading and desprue 4, realizes reliable automatic unloading and desprue 4 operation, and further ensures the production efficiency of the power box 3.

[0094] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
