[0002] The grille is an important component of the speaker. The grille includes the middle tube and the grille cover. The top and bottom of the middle tube are respectively provided with a cavity and a groove. The side of the middle tube is provided with a mounting port that communicates with the groove. The grille cover is installed on the mounting port and has multiple ventilation holes for heat dissipation of the speaker.

[0003] Currently, the middle cylinder is injection molded separately using one set of molds, and the mesh cover is also injection molded separately using one set of molds. Then, the produced mesh cover is welded to the middle cylinder using an ultrasonic process. However, this requires designing two sets of molds and also requires an ultrasonic process, which increases the production cost of the mesh frame. Summary of the Invention

[0004] The purpose of this invention is to provide a mold to solve the technical problem that in the existing wire mesh frame, the middle cylinder and the mesh cover are each injection molded using a separate mold, and then the produced mesh cover is welded to the middle cylinder by ultrasonic process. This requires the design of two sets of molds and an ultrasonic process, which increases the production cost of the wire mesh frame.

Detailed Implementation

[0048] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0049] Please see Figures 1 to 10 As shown, this embodiment of the invention discloses a mold for horizontal installation in an injection molding machine. The mold described in this embodiment is in a vertical state. The mold includes a fixed mold 10 and a moving mold 20 connected to the fixed mold 10.

[0051] The moving mold 20 includes a moving mold plate 30, a mold core 40, a core-pulling module 50, and a sliding module 60 slidably mounted on the moving mold plate 30. The mold core 40 is mounted on the side of the moving mold plate 30 facing the fixed mold plate 11. One end of the core-pulling module 50 is mounted on the mold core 40 and together with the mold core 40 forms a moving mold core 21. The other end of the core-pulling module 50 is mounted on the moving mold plate 30. When the mold is closed or opened, the inclined guide post 13 can be slidably connected to the sliding module 60 to drive the sliding module 60 to move closer to or away from the moving mold core 21. The sliding module 60 has a plurality of first protrusions 611 protruding on the side facing the core-pulling module 50.

[0052] When the mold is closed, multiple first protrusions 611 in the sliding module 60 abut against the core-pulling module 50. The fixed mold core 12, the moving mold core 21, and the sliding module 60 enclose a cavity for a product 70, into which adhesive can be injected. When the mold is opened, the inclined guide post 13 drives the sliding module 60 and its first protrusions 611 to move away from the moving mold core 21, thereby forming multiple ventilation holes 71 on the product 70. In this embodiment, a product 70 with ventilation holes 71 can be produced using a single mold, saving the cost of a single mold. Furthermore, the product 70 does not need to be disassembled, thus improving the production efficiency of the product 70 and reducing its production cost.

[0053] Please refer to the diagram for further details. Figures 5 to 17In this embodiment, the moving mold plate 30 includes a moving mold base plate 31, a moving template 32, an ejector pin assembly plate 33, two pads 34, at least one first ejector pin 35, and at least one second ejector pin 36. The bottom of the product 70 is recessed with an assembly groove 72 communicating with a ventilation hole 71.

One end of the pad 34 is connected to the moving mold base plate 31, and the other end is connected to the moving template 32. The moving mold base plate 31, the moving template 32, and the two pads 34 enclose a transversely penetrating cavity 22. The ejector pin assembly plate 33 is located within the penetrating cavity 22, and the moving template 32 is penetrating through it. There is at least one first through hole 321 and at least one second through hole 322 spaced apart from the first through hole 321. One end of the core-pulling module 50 is connected to the ejector plate 33, and the other end passes through the first through hole 321 and is connected to the mold core 40. One end of the first ejector pin 35 and the second ejector pin 36 are both connected to the ejector plate 33. The other end of the first ejector pin 35 passes through the second through hole 322 and is slidably connected to the moving mold core 21. The other end of the second ejector pin 36 is slidably connected to the core-pulling module 50. The ejector plate 33 is powered by the injection molding machine. The first ejector pin 35 and the second ejector pin 36 can push the product 70 out of the moving mold core 21 through the ejector plate 33.

[0054] The core-pulling module 50 includes a straight ejector block 51, a limiting block 52, at least one first ejector rod 53, and a retractable insert 54 for abutting against a first protrusion 611. The mold core 40 has a cavity 41. The limiting block 52 is fixed to the cavity 41 of the mold core 40 by screws 55. The limiting block 52 has at least one positioning groove 521 vertically penetrating through it. The mold core 40 has a first limiting hole 42 and at least one third through hole 43 vertically penetrating through it. Both the third through hole 43 and the first limiting hole 42 communicate with the cavity 41. The third through hole 43 communicates with the bottom of the positioning groove 521. The straight ejector block 51 has a through hole 511 and at least one... The device includes a fourth through hole 512, at least one fifth through hole 513, and at least one sixth through hole 514. The through hole 511 is horizontally arranged, while the fourth through hole 512, the fifth through hole 513, and the sixth through hole 514 are all vertically arranged. The fourth through hole 512 is spaced apart from the through hole 511. The sixth through hole 514 and the fifth through hole 513 are arranged opposite each other on the upper and lower sides of the through hole 511 and are connected to the through hole 511. One end of the first ejector pin 35 is connected to the ejector pin assembly plate 33, and the other end passes through the second through hole 322, the third through hole 43, and the positioning groove 521 in sequence before being located in the fourth through hole 512.

[0055] The lower end of the straight push block 51 passes through the first limiting hole 42 and is inserted into the first through hole 321. One end of the first push rod 53 is connected to the push pin assembly plate 33, and the other end is connected to the straight push block 51. The shrink insert 54 is partially inserted into the through hole 511 and is inclined and slidably connected to the limiting block 52 in the vertical direction. The shrink insert 54 is used to abut against the first protrusion 611. The shrink insert 54 is vertically provided with at least one second limiting hole 541. The side of the shrink insert 54 away from the limiting block 52 is recessed with at least one forming groove 542 and at least one second limiting hole 541 located in the forming groove 542. The second ejector pin 36 is connected at one end to the ejector pin assembly plate 33 and at the other end to pass through the fifth through hole 513 and the second limiting hole 541 and then to the sixth through hole 514. The second ejector pin 36 can move laterally a small distance in the second limiting hole 541. When the ejector pin assembly plate 33 pushes the straight push block 51 up and down through the first push rod 53, the shrink insert 54 drives each of the second ejector pins 543 on it to move back and forth along the through hole 511 under the cooperation of the limiting block 52, so as to form at least one screw post 73 with a mounting hole on the inner wall of the product 70.

[0056] In some embodiments, the mold core 40 includes a first module 44 and a second module 45 fixedly connected to the first module 44. The cavity 41, the first limiting hole 42 and the third through hole 43 are all provided on the second module 45. The first module 44 and the second module 45 are both mounted on the moving template 32. The structure of the mold core 40 can be set as needed.

[0057] The shrink insert 54 is also provided with at least one groove 544 that is inclined to the running direction of the straight push block 51. The limiting block 52 is provided with a corresponding slide rail 522. The distance from the bottom wall of the groove 544 to the side of the shrink insert 54 away from the limiting block 52 gradually increases from the end near the ejector plate 33 to the end away from the ejector plate 33. The angle between the bottom wall of the groove 544 and the running direction of the straight push block 51, i.e. the vertical direction, is 3 degrees. The slide rail 522 slides in the groove 544. When the straight push block 51 moves up and down, under the constraint of the straight push block 51 and the limiting block 52, the shrink insert 54 can be driven to move laterally back and forth a small distance in the through hole 511 so that when the second protrusion 543 exits the inner wall of the product 70, the screw post 73 can be formed on the product 70.

[0058] The ejector plate 33 includes a first ejector plate group 331 and a second ejector plate group 332 slidably connected to the first ejector plate group 331. The first ejector plate group 331 is located between the second ejector plate group 332 and the moving mold base plate 31. The second ejector plate group 332 is provided with at least one seventh through hole. One end of the first ejector rod 53 is connected to the first ejector plate group 331, and the other end passes through the seventh through hole and is connected to the straight ejector block 51. The first ejector pin 35 and the second ejector pin 36 are both connected to the second ejector plate group 332. The first ejector plate group 331 and the second ejector plate group 332 are both formed by stacking two ejector plates. The two ejector plates in the first ejector plate group 331 are driven to run together by the injection molding machine, and the two ejector plates in the second ejector plate group 332 are also driven to run together by the injection molding machine.

[0059] In some embodiments, a plurality of insert pins 545 are provided on one side of the shrink insert 54 away from the limiting block 52, and each insert pin 545 abuts against each of the first protrusions 611, so that the ventilation hole 71 is formed on the product 70 after the mold is opened.

[0060] The core-pulling module 50 also includes an ejection assembly 56, which includes at least one second ejector rod 561 and a push plate 562 for pushing the product 70 off the moving mold core 21. The push plate 562 is annular and is fitted onto the moving mold core 21. The moving mold plate 32 also has at least one eighth through hole 323. One end of the second ejector rod 561 is connected to the second pin plate assembly 332, and the other end passes through the eighth through hole 323 and is fixedly connected to the push plate 562. After the product 70 is formed, the second pin plate assembly 332 pushes the annular push plate 562 through the second ejector rod 561 to further separate the product 70 from the moving mold core 21. Specifically, at the beginning, the first pin plate assembly 331 and the second pin plate assembly 332... 2. When they run together, the first ejector pin 35, the second ejector pin 36, the first ejector rod 53, the push plate 562, the straight ejector block 51, and the shrink insert 54 move toward the fixed mold 10. At the same time, the shrink insert 54 moves inward along the through hole 511 under the action of the limit block 52. The product 70 is pushed outward by the core pulling module 50, the first ejector pin 35, and the second ejector pin 36. After reaching the middle position of the through cavity 22, the first pin plate group 331, the shrink insert 54, the straight ejector block 51, and the first ejector rod 53 stop running. The second pin plate group 332 continues to push the first ejector pin 35, the second ejector pin 36, the first ejector rod 53, and the push plate 562 to continue running. The second ejection movement separates the product 70 from the straight ejector block 51.

[0061] In some embodiments, the product 70 is further provided with a rib 74 and a plurality of mounting holes 75. The rib 74 is located on the inner wall of the product 70. The top of the mold core 40 and the ejector block 51 are provided with an arc groove 211 that cooperates with the rib 74 and a third protrusion 212 that cooperates with the mounting holes 75. When the product 70 is formed, the ejector block 51 drives the product 70 to rise together. The arc groove 211 and the third protrusion 212 on the mold core 40 first disengage from the corresponding rib 74 and mounting holes 75 on the product 70. Then, the first ejector pin 35, the second ejector pin 36 and the push plate 562 continue to push the product 70 to rise. The arc groove 211 on the ejector block 51 disengages from the rib 74 on the inner wall of the product 70. At the same time, the third protrusion 212 on the ejector block 51 disengages from the mounting holes 75, thereby completing the injection molding of the rib 74 and mounting holes 75 on the product 70.

[0062] In this embodiment, the limiting block 52 is locked onto the mold core 40 for fixation. In the mold-closed state, the retractable insert 54 protrudes 2.13mm from the side of the ejector block 51 away from the limiting block 52. When the ejector block 51 pushes upward, the retractable insert 54 also moves upward due to the upward thrust of the ejector block 51. At the same time, due to the guiding effect of the inclined slide groove 544 on the limiting block 52, the retractable insert 54 will also retract inward. For example, when the ejector block 51 pushes out 100mm... At that time, the shrink insert 54 moves upward 100mm. At the same time, due to the action of the slide groove 544 on the limiting block 52 which is inclined at 3 degrees to the vertical direction, the shrink insert 54 moves from 2.13mm protruding from the straight top block 51 to 3.11mm retracted, that is, it moves 5.24mm, and then disengages from the ventilation hole 71 on the product 70 and the undercut on the screw post 73. Finally, after a second ejection, the bone position 74 and the assembly hole 75 on the product 70 are ejected and then the part can be picked up by the robot arm.

There are four inclined guide pillars 13, which are arranged around the outer periphery of the fixed mold core 12. The first sliding component 61, the second sliding component 62, and the two third sliding components 63 are all slidably mounted on the moving module plate 30 and arranged around the moving mold core 21. The first sliding component 61, the second sliding component 62, and the two third sliding components 63 can be slidably connected to the four inclined guide pillars 13 respectively, so as to drive the first sliding component 61, the second sliding component 62, and the third sliding component 63 to move simultaneously. When the mold is placed horizontally, the first sliding component 61 is located on the top side of the mold, the second sliding component 62 is located on the bottom side of the mold, and the two third sliding components 63 are located on the left and right sides of the mold respectively.

[0064] The first sliding assembly 61 includes a first slide block 612, a first wear-resistant plate 613, a first pressure block 614, and at least one venting insert 615. The first slide block 612 is slidably mounted on the moving module plate 30. The first slide block 612 is provided with a first pressure groove 6121, a first oblique hole 6122 that mates with an oblique guide post 13, and at least one horizontally arranged embedding hole 6123. The first pressure groove 6121 is recessed on the side of the first slide block 612 away from the moving model core 21 and is flush with the embedding hole 612. In this embodiment, there are three exhaust inserts 615 and three embedding holes 6123. The three exhaust inserts 615 are respectively horizontally embedded in the three embedding holes 6123. Multiple first protrusions 611 are respectively provided on the exhaust inserts 615 and the first slide block 612. The first pressure block 614 is installed in the first pressure groove 6121 and positions the exhaust inserts 615. The first wear-resistant plate 613 is installed on the first slide block 612 and covers the first pressure block 614 in the first pressure groove 6121.

[0065] The second sliding assembly 62 includes a second slide block 621 and a second wear-resistant plate 622. The second slide block 621 is slidably mounted on the moving mold plate 30. The second slide block 621 is provided with a second oblique hole 6211 that cooperates with another oblique guide post 13. The second slide block 621 is provided with at least one protruding plate 6212 that abuts against the moving mold core 21, so as to form a product 70 with an observation port 76. The second wear-resistant plate 622 is installed on the side of the second slide block 621 away from the moving mold core 21.

[0066] The third mounting assembly 63 includes a third slide block 631, at least one first elastic element 632, and at least one third ejector pin 633 for abutting against the moving mold core 21. The third slide block 631 is slidably mounted on the moving module plate 30. The third slide block 631 is provided with a third oblique hole 6311 that cooperates with the remaining oblique guide post 13 and a plurality of horizontally arranged insertion holes 6312. One end of the third ejector pin 633 is installed in the insertion hole 6312 through the first elastic element 632, and the other end passes through the insertion hole 6312 and can abut against the moving mold core 21. The first elastic element 632 can be a spring. Under the elastic action of the first elastic element 632, the third ejector pin 633 has the function of delaying the withdrawal of the product 70.

[0067] The third positioning assembly 63 also includes a third wear-resistant plate 634 and a second pressure block 635. The third slide 631 has a second pressure groove 6313 on the side away from the moving model core 21. The second pressure block 635 has a first through hole 6351 through it. The third wear-resistant plate 634 has a second through hole 6341 through it. The second pressure block 635 is installed in the second pressure groove 6313. The third wear-resistant plate 634 is installed on the third slide 631 and covers the second pressure block 635 in the second pressure groove 6313. One end of the third ejector pin 633 is installed in the insertion hole 6312 through the first elastic element 632 and abuts against the moving model core 21. The other end passes through the first through hole 6351 and the second through hole 6341 in sequence and partially protrudes from the third wear-resistant plate 634 to facilitate the fixed installation of the third ejector pin 633.

[0068] In some embodiments, the fixed mold plate 11 is recessed with a receiving groove 1131. When the mold is closed, the part of the third ejector pin 633 protruding outside the third wear-resistant plate 634 can be stored in the receiving groove 1131 to avoid the third ejector pin 633 being damaged. The first wear-resistant plate 613, the second wear-resistant plate 622 and the third wear-resistant plate 634 are all used to prevent the fixed mold 10 from damaging the slide module 60 when the mold is closed.

[0069] In this embodiment, the third slide block 631 is provided with a plurality of fourth protrusions 6314 on the side facing the moving mold core 21. The fourth protrusions 6314 are used to abut against the moving mold core 21 when the mold is closed, so as to form a plurality of mesh holes 77 on the product 70. The number of fourth protrusions 6314 is too large compared to the protrusions on other slide blocks. Therefore, in order to avoid the injection molded product 70 from sticking to the third slide block 631 when the third sliding component 63 is withdrawn, the third ejector pin 633 will still abut against the product 70 for a period of time under the elastic action of the first elastic member 632, delaying separation from the product 70.

[0070] The sliding module 60 also includes a limiting component 64 for preventing the first sliding assembly 61 from sliding down. The limiting component 64 includes a second elastic element 641 and a base 642. The base 642 is mounted on the outer wall of the moving module plate 30. One end of the second elastic element 641 is connected to the base 642 and the other end is connected to the first sliding assembly 61 to prevent the first sliding assembly 61 on the top side from suddenly sliding down after moving up, which would damage the mold. The second elastic element 641 can be a spring.

[0071] In some embodiments, the moving module plate 30 is further provided with a first guide groove 23, a second guide groove 24 disposed opposite to the first guide groove 23, and two third guide grooves 25 disposed opposite to each other. The first slide block 612 is slidably installed in the first guide groove 23, the second slide block 621 is slidably installed in the second guide groove 24, and the third slide block 631 is slidably installed in the third guide groove 25.

[0072] Specifically, the moving module plate 30 also includes multiple pressure plates 37, and the moving template 32 is recessed with four receiving grooves 324. Two pressure plates 37 are installed at both ends of each receiving groove 324. The two pressure plates 37 and the inner wall of the receiving groove 324 enclose each other to form the first guide groove 23, the second guide groove 24, or the third guide groove 25.

[0073] In some embodiments, the moving module plate 30 further includes four fourth wear-resistant plates 38 and eight locking members 39. The bottom wall of the receiving groove 324 is recessed with a first mounting groove 3241 and two second mounting grooves 3242 recessed on the bottom wall of the first mounting groove 3241. The fourth wear-resistant plates 38 are provided with clearance holes 381 for avoiding the locking members 39 and strip holes 382 communicating with the clearance holes 381. The fourth wear-resistant plates 38 are installed in the first mounting groove 3241, and the locking members 39 pass through the clearance holes. After installation in the second mounting slot 3242, the top of the locking member 39 is slightly lower than the top of the fourth wear-resistant plate 38. The bottom of the first sliding component 61, the second sliding component 62 and the third sliding component 63 are all provided with two protruding rods 65. The protruding rods 65 are slidably installed in the strip hole 382 and can be engaged with the locking member 39 at any time to avoid the first sliding component 61, the second sliding component 62 and the third sliding component 63 from continuing to slide relative to the moving module plate 30 after the mold is opened.

[0074] The fixed mold 10 also includes multiple hot runners 14. The fixed mold assembly plate 11 includes a fixed mold base plate 111, a runner plate 112, and a fixed mold plate 113 connected in sequence. The fixed mold core 12 and the inclined guide post 13 are both located on the side of the fixed mold plate 113 away from the runner plate 112. The hot runners 14 are all mounted on the runner plate 112. The fixed mold base plate 111 has a main runner. The runner plate 112 has multiple branch runners that are all connected to the main runner. The fixed mold plate 113 has multiple third through holes for each hot runner 14 to pass through. The fixed mold core 12 has multiple injection ports that are all connected to the cavity. The hot runners 14 have hot runners inside, and one end of the hot runner is connected to the branch runner. The other end is connected to the cavity through the injection port. There are three hot nozzles 14, three through holes and three injection ports. In this embodiment, the cavity of product 70 is injected from three different parts, which effectively avoids shrinkage, bright marks, air marks, drag marks and flash of product 70 during injection molding. The fixed mold base plate 111, runner plate 112, fixed mold plate 113, moving mold base plate 31 and ejector pin assembly plate 33 are all guided by guide rods 26. When the mold is opened, the moving mold assembly plate 30 is also provided with four notches 27 for avoiding each inclined guide post 13. At this time, the notches 27 are connected to the corresponding inclined holes.

[0075] In some embodiments, the mold further includes a plurality of heat dissipation pipes 80, and the moving module plate 30, the core pulling module 50 and the sliding module 60 are all provided with a plurality of heat dissipation pipes 80 for cooling.

[0076] The working principle of the mold:

[0077] When the mold is closed, the moving mold 20 moves toward the fixed mold 10, and the inclined guide pillars 13 are inserted into the corresponding inclined holes. The four inclined guide pillars 13 drive the corresponding first sliding assembly 61, second sliding assembly 62 and two third sliding assembly 63 to move toward the side closer to the moving mold core 21. The pins 545 on the moving mold core 21 abut against the first protrusions 611 on the first sliding assembly 61. The second protrusions 543 on the moving mold core 21 are spaced apart from the sliding module 60. The third protrusions 212 on the moving mold core 21 abut against the fixed mold core 12. The fixed mold core 12, the moving mold core 21 and the sliding module 60 surround and form a cavity of a product 70.

[0078] When the mold opens, the moving mold 20 moves away from the fixed mold 10. The inclined guide pillars 13 on the fixed mold 10 drive the corresponding first sliding assembly 61, second sliding assembly 62, and two third sliding assemblies 63 to move away from the moving mold core 21 simultaneously, until the moving mold 20 separates from the fixed mold 10. At this time, the first protrusion 611 moves away from the moving mold core 21 along with the first sliding assembly 61. Then, the first pin plate assembly 331 and the second pin plate assembly 332 move together under the action of the injection molding machine. The first ejector pin 35, the second ejector pin 36, the first ejector rod 53, the push plate 562, and the straight ejector block 51 move towards the fixed mold 10. The shrink insert 54 also moves towards the fixed mold 10 due to the thrust of the straight ejector block 51. Simultaneously, due to the guiding effect of the 3-degree inclined groove 544 on the limit block 52, the shrink insert 54 also moves along the through hole 51 during its ascent. 1. The insert 545 and the second protrusion 543 in the shrink insert 54 retract to form the ventilation hole 71 and screw post 73 on the product 70 respectively. The product 70 is ejected by the core-pulling module 50. The arc groove 211 and the third protrusion 212 on the mold core 40 first separate from the product 70. After reaching the middle position of the through cavity 22, the first needle plate group 331, the shrink insert 54, the straight ejector block 51 and the first ejector rod 53 stop running. The second needle plate group 332 pushes the first ejector pin 35, the second ejector pin 36 and the push plate 562 to continue running under the action of the injection molding machine. The third protrusion 212 on the straight ejector block 51 separates from the assembly hole 75 on the product 70. At the same time, the arc groove 211 on the straight ejector block 51 separates from the bone position 74 on the inner wall of the product 70, thereby completing the injection molding of the bone position 74 and the assembly hole 75 in the product 70, and finally separating the product 70 from the core-pulling module 50.

[0079] Beneficial effects of molds:

[0080] 1. In this embodiment, the product 70 is traditionally made by welding the mesh cover to the middle cylinder through an ultrasonic process to form the required mesh frame. Now, the mesh cover and the middle cylinder are integrally injection molded, which can reduce the number of parts and reduce the number of molds.

[0081] 2. It reduces assembly steps and avoids potential abnormalities such as incomplete assembly and large gaps after assembly.

[0082] 3. The ultrasonic process is reduced, avoiding problems such as uneven mesh cover and mesh cover detachment after ultrasonication, saving time and labor costs, and improving yield and efficiency.

[0083] In summary, in this invention, the fixed mold 10 has inclined guide pillars 13 and a fixed mold core 12 disposed on the fixed mold assembly plate 11, and the moving mold 20 has a mold core 40, a core-pulling module 50, and a sliding module 60 disposed on the moving mold assembly plate 30. The sliding module 60 slides on the moving mold assembly plate 30, the core-pulling module 50 is connected to the mold core 40 and surrounds the mold core 40 to form the moving mold core 21, and the inclined guide pillars 13 are slidably connected to the sliding module 60. When the mold is closed, multiple first protrusions 611 in the sliding module 60 abut against the mold core 40, and the fixed mold core... 12. The moving mold core 21 and the sliding module 60 enclose a cavity for a product 70. When the mold is opened, the inclined guide post 13 drives the sliding module 60 and its first protrusion 611 to move away from the moving mold core 21, so as to form multiple ventilation holes 71 on the product 70. The product 70 with ventilation holes 71 can be produced using one set of molds. Compared with the traditional two sets of molds, the cost of one set of molds is saved. Moreover, the product 70 does not need to be disassembled, which improves the production efficiency of the product 70 and reduces the production cost of the product 70.
