[0002] With the development of science and technology, more and more plastic products have appeared in people's lives. Plastic products are widely used in various fields due to their easy processing and manufacturing, light weight, high strength, no rust and corrosion resistance. Against the background of increasing demand for plastic products, two-color injection molding and injection molding methods that add inserts to assist injection molding during the injection molding process have been developed.

[0003] In the production process of injection molding products, tiny inserts are needed to assist in injection molding. Because the tiny inserts used are small in size, when the injection molding machine is working, the tiny inserts may be placed in the movable mold, which may result in unqualified products. At the same time, even if the tiny inserts are placed in the correct position, they may be offset due to their small size and difficulty in positioning. In addition, the distance between the movable mold and the fixed mold is small when the mold is opened, so it is more difficult to place the tiny inserts between the movable mold and the fixed mold.

[0004] Therefore, how to improve the positioning accuracy of the micro-insert and make the placement of the micro-insert easier is a problem that those skilled in the art need to solve. Summary of the invention

[0053] Please refer to Figures 1 to 4 , which shows a rotary multi-station mold-outside quick-install insert injection mold provided in an embodiment of the present invention, comprising:

[0054] A turntable 1 is provided with a plurality of stations arranged in a circle around the center of the rotating shaft of the turntable 1, wherein the plurality of stations include a first station 11, a second station 12, a third station 13 and a fourth station 14. A movable mold 15 is installed at each station of the turntable 1, and an embedding groove 16 is provided in the movable mold 15. When the turntable 1 rotates, it can drive the movable mold 15 to be in the first station 11, the second station 12, the third station 13 and the fourth station 14 in sequence;

[0055] The first fixed mold 2 is arranged on the second station 12 and faces the turntable 1. The first fixed mold 2 is used to perform a single injection molding with the movable mold 15 on the second station 12;

[0056] The second fixed mold 3 is arranged on the fourth station 14 and faces the turntable 1. The second fixed mold 3 is used to close the mold with the movable mold 15 on the fourth station 14 for secondary injection molding;

[0057] The quick-install assembly 4 includes a quick-install fixture 41 and an insert 42 mounted on the quick-install fixture 41. The quick-install fixture 41 is arranged outside the movable mold 15, and the quick-install fixture 41 can be embedded and installed in the embedding groove 16 or removed from the embedding groove 16;

[0058] The limiting component 5 is used to limit and fix the quick-installing fixture 41 in the embedding groove 16 when the quick-installing component 4 is embedded and installed in the embedding groove 16;

[0059] The unlocking assembly 6 is used to drive the limiting assembly 5 to release the limiting fixation of the quick-installing fixture 41 when it is necessary to remove the quick-installing fixture 41 from the embedding groove 16.

[0060] like Figure 1 As shown, in this embodiment, the turntable 1 is square, and there are four faces around the center of the rotation axis of the turntable 1, which correspond to the first station 11, the second station 12, the third station 13 and the fourth station 14. Then the turntable 1 is also correspondingly installed with four movable molds 15, so as to ensure that when the turntable 1 rotates, each position corresponds to a movable mold 15.

[0061] The second station 12 is provided with a first fixed mold 2 , which is arranged opposite to the movable mold 15 on the second station 12 , so that the first fixed mold 2 can be molded with the movable mold 15 to complete one injection molding.

[0062] Similarly, the fourth station 14 is provided with a second fixed mold 3 , which is arranged opposite to the movable mold 15 on the fourth station 14 , so that the second fixed mold 3 can be molded with the movable mold 15 to complete secondary injection molding.

[0063] The first station 11 and the third station 13 are correspondingly provided with assembly equipment of the quick assembly component 4, which is used to place the parts needed for injection molding on the corresponding movable mold 15 before the first injection molding and the second injection molding.

[0064] In this embodiment, the insert 42 needs to be placed in the movable mold 15 for injection molding. Because the volume of the insert 42 is too small, if the insert 42 is directly placed in the movable mold 15, it is difficult to position the insert 42 in the movable mold 15. In this embodiment, the insert 42 is first placed on the quick-install jig 41, and the insert 42 is positioned by the quick-install jig 41, so that the insert 42 is positioned in the quick-install jig 41, and the insert 42 and the quick-install jig 41 are combined together to form a quick-install assembly 4, and then the quick-install assembly 4 with the insert 42 positioned is assembled on the movable mold 15. Because the size of the quick-install jig 41 can be adjusted according to the actual size of the movable mold 15, the volume of the quick-install jig 41 is much larger than the volume of the insert 42. Compared with the insert 42, the quick-install jig 41 can be placed in the movable mold 15 for positioning more simply and conveniently.

[0065] In this embodiment, the quick-installing fixture 41 is used to position the insert 42 in advance outside the mold to form the quick-installing assembly 4, which increases the volume of the quick-installing fixture 41 when it is placed into the moving mold 15, making it easier to grasp the quick-installing fixture 41 and place it into the moving mold 15. The insert 42 and the quick-installing fixture 41 can be pre-assembled to form the quick-installing assembly 4, so that at the first station 11, the quick-installing assembly 4 pre-assembled with the insert 42 can be directly placed into the moving mold 15 located at the first station 11.

[0066] Meanwhile, a square turntable 1 is designed, which can provide the first station 11 in addition to the injection molding stations (the second station 12 and the fourth station 14). Since there is only the moving mold 15 at the first station 11 and no stationary mold to block, there is enough space to place the quick-installing assembly 4 into the moving mold 15, so that the assembly of the quick-installing fixture 41 on the moving mold 15 is not restricted by the mold opening gap. An embedding groove 16 corresponding to the quick-installing assembly 4 is provided in the moving mold 15, and the quick-installing fixture 41 can be embedded and installed in the embedding groove 16 by manual or mechanical control.

[0067] In this embodiment, the insert 42 and the quick-installing fixture 41 are first positioned and connected, and the insert 42 is positioned by the quick-installing fixture 41. Then, the quick-installing fixture 41 is fixedly connected to the moving mold 15 through the embedding groove 16, thereby indirectly realizing the positioning of the insert 42 and the moving mold 15.

[0068] Specifically, as Figure 4 shown, multiple injection molding areas can be provided on the moving mold 15. In this embodiment, four injection molding areas are provided on the moving mold 15 in a "field" shape distribution, and an embedding groove 16 is provided in each injection molding area, so that four quick-installing assemblies 4 can be embedded and installed on the moving mold 15. Please refer to Fig.11 , one or more inserts 42 ( Fig.11 shows four) can be positioned and installed on the quick-installing fixture 41 of each quick-installing assembly 4. In this way, multiple final injection molded products can be produced simultaneously in one cycle of injection molding to increase the production efficiency of injection molding.

[0069] As Figure 2 shown, the first stationary mold 2 includes a first positioning strip 21, a first positioning boss 22, and a first cavity 23. Specifically, multiple injection molding areas are correspondingly provided on the first stationary mold 2. In this embodiment, four injection molding areas are provided on the first stationary mold 2 in a "field" shape distribution, and multiple first cavities 23 ( Figure 2 shows four) are provided in each injection molding area.

[0070] As Figure 3As shown, the second fixed mold 3 includes a second positioning strip 31, a second positioning boss 32, and a second cavity 33. Specifically, a plurality of injection areas are correspondingly provided on the second fixed mold 3. In this embodiment, four injection areas distributed in a "field" shape are provided on the second fixed mold 3, and a plurality of second cavities 33 are provided in each injection area ( Figure 3 four are schematically shown).

[0071] As Figure 4 shown, a first positioning groove 151, a second positioning groove 152, and a core 153 are provided on the moving mold 15. The first positioning groove 151 corresponds to the first positioning strip 21 on the first fixed mold 2 and the second positioning strip 31 on the second fixed mold 3. The second positioning groove 152 corresponds to the first positioning boss 22 on the first fixed mold 2 and the second positioning boss 32 on the second fixed mold 3. When the moving mold 15 is at the second working position 12, the first positioning groove 151 is aligned with the first positioning strip 21 on the first fixed mold 2, and the second positioning groove 152 is aligned with the first positioning boss 22 on the first fixed mold 2, and then the mold is closed so that the core 153 is aligned with the first cavity 23 for the first injection. When the moving mold 15 is at the fourth working position 14, the first positioning groove 151 is aligned with the second positioning strip 31 on the second fixed mold 3, and the second positioning groove 152 is aligned with the second positioning boss 32 on the second fixed mold 3, and then the mold is closed so that the core 153 is aligned with the second cavity 33 for the second injection.

[0072] Please refer to Figures 1 to 4 together. After the quick - mounting component 4 is assembled at the first working position 11, the turntable 1 can be started to drive the moving mold 15 at the first working position 11 to the second working position 12. Since the turntable 1 in this embodiment is a square turntable and there are four working positions and they are symmetrically arranged, the turntable 1 rotates 90° each time in this embodiment. When the moving mold 15 rotates to the second working position 12 and is aligned with the first fixed mold 2, the mold can be closed for injection. When the moving mold 15 and the first fixed mold 2 are closed, the first positioning strip 21 is inserted into the first positioning groove 151, and the first positioning boss 22 is inserted into the second positioning groove 152, so that the moving mold 15 and the first fixed mold 2 can be aligned with each other. At the same time, the first cavity 23 and the core 153 jointly form a first injection cavity. After the moving mold 15 at the second working position 12 completes the first injection, the mold is opened.

[0073] After completing one injection molding, the turntable 1 is started to drive the movable mold 15 at the second station 12 to rotate to the third station 13, where the second insert can be placed. That is to say, if two inserts are required in the final injection-molded product, the second insert can be installed on the movable mold 15 at the third station 13. In this embodiment, the final injection-molded product contains only one insert, so it is only necessary to place the insert 42 on the quick-install fixture 41 once, and the movable mold 15 at the third station 13 waits without additional operations. In other embodiments, if the second insert needs to be placed at the third station 13, the second insert can be installed on the movable mold 15 at the third station 13 so that the final injection-molded product contains two inserts.

[0074] Then, the turntable 1 is started again to drive the movable mold 15 in the third station 13 to rotate to the fourth station 14, and after being aligned with the second fixed mold 3, the mold can be closed for injection. When the movable mold 15 is closed with the second fixed mold 3, the second positioning bar 31 is inserted into the first positioning groove 151, and the second positioning boss 32 is inserted into the second positioning groove 152, so that the movable mold 15 and the second fixed mold 3 can be aligned with each other, and the second cavity 33 and the core 153 are combined to form a secondary injection cavity, and secondary injection molding is performed to form a secondary injection molded product. After the movable mold 15 in the fourth station 14 completes the secondary injection molding, the mold is opened.

[0075] After completing the secondary injection molding, the turntable 1 is started again to drive the movable mold 15 at the fourth station 14 back to the first station 11, and the quick-release assembly 4 in the movable mold 15 and the secondary injection molded product are taken out from the embedding groove 16 together, and then a new quick-release assembly 4 equipped with an insert is put into the embedding groove 16 of the movable mold 15 again to start the next injection molding.

[0076] At this point, a single working process of a single movable mold 15 is completed. Because there are four movable molds 15 on the turntable 1 in this embodiment, each station can have a movable mold 15 working, and uninterrupted injection molding can be performed, thereby improving injection molding efficiency. For example, when a primary injection molding operation is performed at the second station 12, a secondary injection molding operation is also performed at the fourth station 14, and at the same time, the first station 11 is also performing an operation of removing the injection-molded quick-fit component 4 from the movable mold 15 and reinstalling a new quick-fit component 4 on the movable mold 15.

[0077] It can be understood that the present embodiment is a square turntable 1 with four workstations arranged symmetrically, so the turntable 1 in the present embodiment rotates 90° each time, but is not limited to this. In other embodiments, the turntable 1 can also be a polygonal turntable, such as an octagon. In this case, there are eight workstations arranged symmetrically, and the turntable 1 rotates 45° each time.

[0078] Please refer to Figures 5 to 11In this embodiment, when the quick-assembly component 4 is installed on the movable mold 15, in order to limit and fix the quick-assembly component 4 in the embedding groove 16, the rotary multi-station mold outside the quick-assembly insert injection mold also includes a limiting component 5. The limiting component 5 is used to limit and fix the quick-assembly fixture 41 in the embedding groove 16 when the quick-assembly component 4 is embedded and installed in the embedding groove 16.

[0079] Correspondingly, the rotary multi-station mold outside quick-install insert injection mold also includes an unlocking component 6, which is used to drive the limiting component 5 to release the limiting fixation of the quick-install fixture 41 when it is necessary to remove the quick-install fixture 41 from the embedding groove 16, so that the quick-install component 4 can be removed from the embedding groove 16 after the injection molding is completed.

[0080] In one embodiment, the limit assembly 5 includes a limit slot 44, a limit sliding member 51 and a first elastic member 52. The limit slot 44 is set on the quick-release fixture 41. The limit sliding member 51 is slidable. The limit sliding member 51 is provided with a limit block 510 at one end close to the limit slot 44. The first elastic member 52 provides an elastic force so that the limit sliding member 51 has a tendency to move toward the limit slot 44. Under the action of the elastic force, the limit block 510 is inserted into and limited in the limit slot 44.

[0081] In this embodiment, the limit slot 44 is arranged on the side of the quick-release fixture 41, and a first slide groove 155 is penetrated on the side wall of the movable mold 15. The limit sliding member 51 is accommodated in the first slide groove 155, and the limit sliding member 51 can slide in the first slide groove 155 in a direction toward or away from the limit slot 44.

[0082] Furthermore, the limiting assembly 5 also includes a fixed seat 53, which is fixed on the movable mold 15, one end of the first elastic member 52 abuts against the fixed seat 53, and the other end of the first elastic member 52 abuts against an end of the limiting sliding member 51 where the limiting block 510 is not provided, thereby utilizing the elastic force provided by the first elastic member 52 to push the limiting sliding member 51 to have a tendency to move toward the limiting slot 44, so that the limiting block 510 is inserted into and limited in the limiting slot 44.

[0083] Specifically, the first slide groove 155 is provided on the side wall of the movable mold 15 in a direction perpendicular to the central axis of the quick-loading fixture 41, so that the limiting sliding member 51 can slide in the first slide groove 155 in a direction perpendicular to the central axis of the quick-loading fixture 41 toward or away from the limiting card slot 44. The bottom of the limiting card block 510 is a plane, and the top is an inclined surface or an arc surface, so that when the quick-loading fixture 41 is installed in the embedding groove 16, the inclined surface or the arc surface on the top of the limiting card block 510 can be squeezed, so that the limiting card block 510 is squeezed and retracted into the first slide groove 155, so that the quick-loading fixture 41 is smoothly embedded and installed in the embedding groove 16. At the same time, after the limiting card block 510 is inserted into the limiting card slot 44, the plane at the bottom thereof can be stuck in the limiting card slot 44 to effectively prevent the limiting card block 510 from being separated from the limiting card slot 44. The first elastic member 52 can be a spring, a spring or other elastic member that can provide elastic force. The number of the limiting components 5 can be multiple and they can be arranged around the quick-install fixture 41 , so that the quick-install fixture 41 can be stably limited and fixed in the embedding groove 16 .

[0084] In this embodiment, a through hole 511 is penetrated through the limit sliding member 51, and the through hole 511 has a first inclined surface 512. The unlocking component 6 includes an unlocking rod 61 with a second inclined surface 62. The unlocking rod 61 passes through the through hole 511 in a direction parallel to the central axis of the quick-release fixture 41 and abuts against the first inclined surface 512 through the second inclined surface 62, so that the limit sliding member 51 is pushed in a direction away from the limit card slot 44 to disengage the limit card block 510 from the limit card slot 44 and unlock it.

[0085] Specifically, the through hole 511 is arranged through the limiting sliding member 51 in a direction parallel to the central axis of the quick-loading fixture 41, so that the unlocking rod 61 can pass through the through hole 511 in a direction parallel to the central axis of the quick-loading fixture 41, and squeeze and push the first inclined surface 512 through the second inclined surface 62, so as to move the limiting sliding member 51 in a direction away from the limiting slot 44 so that the limiting block 510 is disengaged from the limiting slot 44 and unlocked, and at the same time, the first elastic member 52 is further compressed by the limiting sliding member 51.

[0086] After the quick-loading jig 41 is unlocked, in order to facilitate the grasping of the quick-loading jig 41 to remove the quick-loading jig 41 from the embedding groove 16, the rotary multi-station mold outside quick-loading insert injection mold also includes an ejector pin 10 located below the quick-loading jig 41. The ejector pin 10 can move toward the quick-loading jig 41 in a direction parallel to the central axis of the quick-loading jig 41 and push the quick-loading jig 41. The ejector pin 10 is used to eject the quick-loading jig 41 from the embedding groove 16 by a certain distance or completely after the quick-loading jig 41 is unlocked.

[0087] Please refer to Fig.12 and Fig.13In another embodiment, the bottom surface of the quick-install fixture 41 is inwardly recessed to form a recess 45, and the bottom of the quick-install fixture 41 protrudes toward the recess 45 to form a protrusion 46, and the limiting slot 44 is provided on the side of the protrusion 46, and the limiting sliding member 51 is located on the bottom surface of the quick-install fixture 41, and the limiting sliding member 51 can slide on the bottom surface of the quick-install fixture 41 in a direction toward or away from the limiting slot 44. Specifically, the protrusion 46 can be a component separated from the quick-install fixture 41, and the protrusion 46 can be connected to the quick-install fixture 41 by a fixing member (such as a screw). Of course, in other embodiments, the protrusion 46 can also be formed integrally with the quick-install fixture 41.

[0088] Furthermore, in this other embodiment, one end of the limiting sliding member 51 having the limiting block 510 extends toward the recess 45 to form an extension portion 513 , the extension portion 513 extends into the recess 45 , and the limiting block 510 is disposed at the top end of the extension portion 513 .

[0089] Furthermore, in this other embodiment, one end of the first elastic member 52 directly abuts against the movable mold 15, and the other end of the first elastic member 52 abuts against an end of the limiting sliding member 51 where the limiting block 510 is not provided, thereby utilizing the elastic force provided by the first elastic member 52 to push the limiting sliding member 51 to have a tendency to move toward the limiting slot 44, so that the limiting block 510 is inserted into and limited in the limiting slot 44.

[0090] In this other embodiment, the unlocking rod 61 further acts as an ejector pin. After the unlocking rod 61 moves the limiting sliding member 51 in a direction away from the limiting card slot 44 so that the limiting card block 510 is disengaged from the limiting card slot 44 and unlocked, the unlocking rod 61 continues to move toward the quick-loading fixture 41 in a direction parallel to the central axis of the quick-loading fixture 41 and pushes the quick-loading fixture 41. After the quick-loading fixture 41 is unlocked, the quick-loading fixture 41 is ejected a certain distance or completely from the embedding groove 16. Therefore, in this other embodiment, the unlocking rod 61 can be used as an ejector pin. The top of the unlocking rod 61 extends into the recess 45 and pushes the quick-loading fixture 41 to eject the quick-loading fixture 41, thereby eliminating the need for the ejector pin 10 additionally provided in the first embodiment, resulting in a more streamlined structure and more convenient operation.

[0091] For other structures of this another embodiment, reference may be made to the above-mentioned first embodiment and will not be described in detail here.

[0092] Please refer to Figures 7 to 11In order to more stably position the quick-install fixture 41 in the embedding groove 16, the external quick-install insert injection mold further includes a positioning component 17, the positioning component 17 includes a positioning recess 43, a positioning slide 173 and a second elastic member 171, the positioning recess 43 is arranged on the quick-install fixture 41, the positioning slide 173 is slidable, and the positioning slide 173 is provided with a positioning protrusion 1731 at one end close to the positioning recess 43, and the second elastic member 171 provides an elastic force to make the positioning slide 173 have a tendency to move toward the positioning recess 43, and under the action of the elastic force, the positioning protrusion 1731 is stuck in and positioned in the positioning recess 43.

[0093] In this embodiment, the positioning recess 43 is arranged on the side of the quick-release fixture 41, and a second slide groove 156 is penetrated on the side wall of the movable mold 15. The positioning sliding member 173 is accommodated in the second slide groove 156. The positioning sliding member 173 can slide in the second slide groove 156 in a direction toward or away from the positioning recess 43.

[0094] Furthermore, the positioning assembly 17 also includes a pressure plate 172, which is fixed on the movable mold 15, and one end of the second elastic member 171 abuts against the pressure plate 172, and the other end of the second elastic member 171 abuts against an end of the positioning slide 173 where the positioning protrusion 1731 is not provided, thereby utilizing the elastic force provided by the second elastic member 171 to push the positioning slide 173 to have a tendency to move toward the positioning recess 43, so that the positioning protrusion 1731 is stuck in and confined in the positioning recess 43.

[0095] Specifically, the second slide groove 156 is arranged on the side wall of the movable mold 15 in a direction perpendicular to the central axis of the quick-loading fixture 41, so that the positioning slide 173 can slide in the second slide groove 156 in a direction perpendicular to the central axis of the quick-loading fixture 41 toward or away from the positioning recess 43. The bottom and top of the positioning protrusion 1731 are both inclined surfaces or curved surfaces, so that when the quick-install fixture 41 is installed in the embedding groove 16, the inclined surface or curved surface on the top of the positioning protrusion 1731 can be squeezed, so that the positioning protrusion 1731 is squeezed and retracted into the second slide groove 156, thereby smoothly realizing the quick-install fixture 41 being embedded and installed in the embedding groove 16. At the same time, when the ejector pin 10 moves toward the quick-install fixture 41 in a direction parallel to the central axis of the quick-install fixture 41 and pushes the quick-install fixture 41, the ejector pin 10 can also push the positioning protrusion 1731 to disengage from the positioning recess 43 and retract into the second slide groove 156, which will not hinder the smooth ejection of the quick-install fixture 41. When the positioning protrusion 1731 is retracted into the second slide groove 156, the positioning slide 173 will further compress the first elastic member 52. The second elastic member 171 can be a spring, a spring sheet or other elastic member that can provide elastic force. A plurality of positioning components 17 can be provided and arranged around the quick-install fixture 41 , so that the quick-install fixture 41 can be stably positioned in the embedding groove 16 .

[0096] Furthermore, a guide plate 154 is provided at the bottom of the movable mold 15, and the unlocking rod 61 and the ejector pin 10 both pass through the guide plate 154. The guide plate 154 keeps the unlocking rod 61 and the ejector pin 10 in a more accurate movement direction, and both move in a direction parallel to the central axis of the quick-release fixture 41.

[0097] In this embodiment, the unlocking rod 61 and the ejector pin 10 can be driven to move synchronously, so the ejector pin 10 is arranged at a distance from the bottom of the quick-install fixture 41, that is, before the ejector pin 10 is ejected, there is a certain distance between the top surface of the ejector pin 10 and the bottom surface of the quick-install fixture 41. Figure 7 and Figure 8 As shown, in this embodiment, the distance between the top surface of the ejector pin 10 and the bottom surface of the quick-install fixture 41 is 7 mm, but it is not limited thereto and can be adjusted according to actual needs. When the unlocking rod 61 starts to move toward the quick-install fixture 41 to unlock the limiting sliding member 51, the ejector pin 10 also moves toward the quick-install fixture 41 synchronously. Fig. 9 and Fig.10 As shown, after the unlocking rod 61 moves upward by 7 mm, the limiting sliding member 51 is pushed to completely withdraw from the limiting slot 44, and at the same time, the top surface of the ejector pin 10 is just in contact with the bottom surface of the quick-loading fixture 41. At this time, the limiting sliding member 51 on the quick-loading fixture 41 is released, and then the ejector pin 10 pushes the quick-loading fixture 41 upward again, and the quick-loading fixture 41 can be ejected upward.

[0098] Please refer to Figure 5 and Figure 6 In this embodiment, the external quick-install insert injection mold also includes a hydraulic drive system for driving the unlocking rod 61 and the ejector pin 10 to move. Specifically, the hydraulic drive system includes a fixed base plate 54, an oil cylinder 55, a connecting rod 56, a fixed base plate 57, a connecting rod pressure plate 58, and an ejection limit block 59. The oil cylinder 55 is installed on the fixed base plate 54, and the oil cylinder 55 is transmission-connected with the unlocking rod 61 and the ejector pin 10 to drive the unlocking rod 61 and the ejector pin 10 to move up and down. The unlocking rod 61 and the ejector pin 10 are both fixedly installed on the fixed base plate 57, and the fixed base plate 57 is connected to the fixed base plate 54 through the connecting rod 56, one end of the connecting rod 56 is fixedly connected to the fixed base plate 57, and the other end of the connecting rod 56 is slidably connected to the fixed base plate 54.

[0099] Driven by the oil cylinder 55, the fixed base plate 57 and the connecting rod 56 can move toward or away from the fixed base plate 54, thereby driving the unlocking rod 61 and the ejector 10 to move up and down. An ejection limit block 59 is fixedly provided above the fixed base plate 57. When the fixed base plate 57 drives the unlocking rod 61 and the ejector 10 to move upward in a direction away from the fixed base plate 54, the moving distance of the fixed base plate 57 is limited by the ejection limit block 59. At the same time, a connecting rod pressing plate 58 is provided on the fixed base plate 57 at a position directly opposite to the ejection limit block 59. The connecting rod pressing plate 58 abuts against the ejection limit block 59, so that the connecting rod 56 can be protected.

[0100] In one embodiment, the rotary multi-station mold-outside quick-install insert injection mold further includes an installation component 110, the installation component 110 includes a suction nozzle 1101 and a guide 1102, the guide 1102 is used to guide the quick-install fixture 41, the suction nozzle 1101 is used to suck the insert 42, and put the sucked insert 42 into the quick-install fixture 41 to complete the assembly of the quick-install component 4. In one embodiment, the rotary multi-station mold-outside quick-install insert injection mold further includes a detection device 7, the detection device 7 includes a conveyor belt 71 and an optical detection module 72, the optical detection module 72 is arranged opposite to the conveyor belt 71, the conveyor belt 71 is used to convey the assembled quick-install component 4, and the optical detection module 72 is used to generate an image of the quick-install component 4 on the conveyor belt 71. In one embodiment, the detection device 7 further includes an insert removal device 73 , which is arranged in front of the optical detection module 72 along the conveying direction of the conveyor belt 71 , and is used to grab the quick-install components 4 on the conveyor belt 71 that have not passed the inspection.

[0101] like Fig.14 and Fig.15, an installation component 110 of a quick-install component 4 is provided. In this embodiment, mechanical automatic installation is adopted. In other embodiments, manual assembly can also be adopted. The guide member 1102 can be in the form of a clamp. In this embodiment, the guide member 1102 is two sliders 11021 arranged opposite to each other. The sliders 11021 are connected by springs. Under the drive of the springs, the two sliders 11021 move toward each other to achieve a guiding function. A fixed core 411 for positioning the insert 42 is provided on the quick-install jig 41. When the guide member 1102 clamps the quick-install jig 41, the fixed core 411 is located at the center of the two sliders 11021. Therefore, when the two sliders 11021 move toward the center, the fixed core 411 can also be corrected. The suction nozzle 1101 is connected to the robot arm 1103, and can be moved to the storage area of ​​the insert 42 under the drive of the robot arm 1103, suck out the insert 42, and then move to the top of the quick-install jig 41 and face the fixed core 411, and insert the insert 42 into the fixed core 411 through the suction nozzle 1102 under the drive of the robot arm 1103. When the insert 42 is inserted into the fixed core 411, the suction nozzle 1102 changes from suction to blowing, and further positions the insert 42 in the fixed core 411, thereby completing the assembly of the insert 42 and the quick-install jig 41.

[0102] Furthermore, in this embodiment, when the two sliders 11021 move toward each other to clamp the fixed core 411, because the distance between the two sliders 11021 is small, the suction nozzle 1101 is not enough to enter, so the two sliders 11021 need to be opened to increase the distance between the two sliders 11021. In this embodiment, the two sliders 11021 are provided with a guide surface 11022 on the side facing the suction nozzle 1101, and at the same time, the two sides of the suction nozzle 1101 are provided with inclined surfaces corresponding to the guide surface 11022. When the robot arm 1103 drives the suction nozzle 1101 to move toward the fixed core 411, the inclined surface abuts against the guide surface 11022, thereby pushing the two sliders 11021 to both sides, so that the suction nozzle 1101 can insert the insert 42 into the fixed core 411.

[0103] like Fig.16 As shown, the assembled quick-install component 4 is transported to the conveyor belt 71 and is transported to the next workstation driven by the conveyor belt 71. Above the conveyor belt 71, an optical inspection module 72 is provided facing the conveyor belt 71. The optical inspection module 72 includes a CCD camera and a visual inspection system. The CCD camera captures the graphic information of each quick-install component 4 on the conveyor belt 71, and transmits the image information to the visual inspection system for judgment to detect whether the insert 42 on the quick-install fixture 41 is installed correctly.

[0104] like Fig.17 and Fig.18As shown, in this embodiment, an insert removal device 73 is arranged adjacent to the optical inspection module 72. When the optical inspection module 72 detects a quick-install component 4 that does not meet the requirements, a failure signal is transmitted to the insert removal device 73, and the insert removal device 73 removes the quick-install component 4 that fails the inspection from the conveyor belt 71.

[0105] Specifically, the insert removal device 73 can place the quick-install component 4 that has not passed the inspection into the unqualified product area, waiting for reassembly. In this embodiment, a correction nozzle 74 is provided on the insert removal device 73. After the insert removal device 73 clamps the quick-install component 4 that has not passed the inspection, the correction nozzle 74 sucks out the insert 42 on the quick-install fixture 41, adjusts the position of the insert 42 by suction of the correction nozzle 74, and then the correction nozzle 74 reinserts the insert 42 into the quick-install fixture 41 to complete the correction of the insert 42. After the correction is completed, the insert removal device 73 puts the corrected quick-install component 4 back on the conveyor belt 71.

[0106] Furthermore, in this embodiment, optical detection modules 72 are provided at the front and rear of the insert removal device 73. When the insert removal device 73 puts the calibrated quick-install component 4 back to the conveyor belt 71, the optical detection module 72 in front of the insert removal device 73 re-detects the calibrated quick-install component 4 to ensure that the calibrated quick-install component 4 is a qualified product. At the same time, optical detection modules 72 are provided at the front and rear of the insert removal device 73 to perform secondary detection on the quick-install component 4 on the conveyor belt 71 to improve the detection accuracy.

[0107] In one embodiment, the rotary multi-station mold-outside quick-install insert injection mold also includes an assembly component 8, which includes a manipulator 81 and a telescopic column 82. The telescopic column 82 is connected to the side of the manipulator 81 facing the quick-install component 4, and the telescopic column 82 is opposite to the insert 42. The manipulator 81 is used to grab the quick-install component 4 and embed the quick-install component 4 into the embedding groove 16, and the telescopic column 82 is used to abut against the insert 42 when the manipulator 81 grabs the quick-install component 4.

[0108] like Fig.19 and Fig. 20As shown, in this embodiment, the assembly component 8 is used to install the quick-assembly component 4. The manipulator 81 is arranged between the conveyor belt 71 and the first station 11, and the manipulator 81 is used to grab the quick-assembly component 4 on the conveyor belt 71. When the manipulator 81 grabs, it drives the telescopic column 82 to move toward the quick-assembly component 4. When the manipulator 81 grabs the quick-assembly component 4, the telescopic column 82 abuts against the insert 42, and under the drive of the manipulator 81, the telescopic column 82 is compressed downward, that is, compressed in the direction of the insert 42. Under the elastic force of the telescopic column 82, the insert 42 can be pressed against the quick-assembly fixture 41, thereby preventing the insert 42 from falling during the transportation process of the manipulator 81. After the manipulator 81 successfully grabs the quick-assembly component 4, the quick-assembly component 4 is embedded in the embedding groove 16 of the movable mold 15 by the manipulator 81 to complete the assembly at the first station 11.

[0109] For further information, please refer to Fig.21 and Fig. 22 In this embodiment, a sealed air circuit 91 is also provided in the movable mold 15. After the quick-release assembly 4 is embedded in the embedding groove 16, the sealed air circuit 91 is inserted from the other end of the fixed core 411. The sealed air circuit 91 and the insert 42 are arranged at opposite ends of the fixed core 411 to seal the fixed core 411 together. The end of the sealed air circuit 91 that is not inserted into the fixed core 411 is an air circuit connector 92, which is connected to an air suction device through the air circuit connector 92. After the sealed air circuit 91 is inserted into the fixed core 411, the air suction device is started to suction. Because both ends of the fixed core 411 are sealed, negative pressure is generated when the air suction device suctions. When the injection molding machine receives the negative pressure signal, it can be started to close the mold.

[0110] When the insert 42 falls off during the rotation of the turntable 1, the fixed core 411 will no longer be sealed, and the suction device will not generate a negative pressure signal when suctioning. When the injection molding machine does not receive the negative pressure signal, it stops closing the mold.

[0111] In this embodiment, the core 411 is sealed and fixed by the sealing gas path 91 and the insert 42 , and then it is determined whether the insert 42 falls off according to the negative pressure signal, thereby further improving the accuracy of the injection molding process.

[0112] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
