Description

Technical Field

[0001] The present invention relates to the technical field of injection molding equipment, and particularly to a separating mechanism for an injection molded product and a mold core. Background Art

[0002] ‌The mold core‌ is the core component in an injection mold. It is located at the center of the injection mold and is responsible for the molding of products. The mold core is one of the parts with the most complex structure, the greatest processing difficulty, and the highest cost in an injection mold. Its function is to inject plastic into the mold under a high-temperature and high-pressure environment and form it into the required plastic products.‌

[0003] After some products are injection molded, it is necessary to take out the mold core with the product from the mold, and then separate the product from the mold core. The current general method is as follows: Use a manipulator to take out the mold core with the product from the mold and place it on a positioning fixture, then transport the mold core to a designated position, and manually separate the product from the mold core. After completion, place the mold core on the positioning fixture again, and then the manipulator takes the mold core and puts it into the mold. Since manual disassembly of the product and the mold core is required in the above process, the production efficiency is low, the production cost is high, which is not conducive to large-scale mass production.

[0049] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the injection product and mold core separation mechanism and the automation equipment proposed according to the present invention are described in detail as follows:

[0050] As Figures 1 to 17 shown, the embodiment of the present invention provides an injection product and mold core separation mechanism for separating the product 91 and the mold core 92 in the part to be separated 9 (that is, the part to be separated 9 includes the product 91 and the mold core 92). Since the product 91 is injection-molded on the basis of the mold core 92, the local structure of the product 91 is shaped like the mold core 92, and at least part of the position of the product 91 is mutually engaged with the mold core 92. The injection product and mold core separation mechanism has a front-back direction X and a left-right direction Y that are perpendicular to each other. The injection product and mold core separation mechanism includes:

[0051] A base 1;

[0052] A transplanting mechanism 2, which is arranged on the base 1; the transplanting mechanism 2 is successively provided with a product placing station 2A, a separation station 2B and a product taking station 2C along the front-back direction X, and the product placing station 2A, the separation station 2B and the product taking station 2C are arranged in sequence from back to front;

[0053] An upper disassembly mechanism 3, which is arranged at the separation station 2B;

[0054] The lower disassembly mechanism 4 is arranged on the transplanting mechanism 2. The transplanting mechanism 2 is used to drive the lower disassembly mechanism 4 to move in the front-rear direction X, so that the lower disassembly mechanism 4 can switch positions among the product placing station 2A, the separation station 2B, and the product taking station 2C. When the lower disassembly mechanism 4 moves to the separation station 2B, the lower disassembly mechanism 4 is located directly below the upper disassembly mechanism 3.

[0055] The lower disassembly mechanism 4 is used to receive the to-be-separated part 9 after injection molding by an injection mold (not shown) at the product placing station 2A, cooperate with the upper disassembly mechanism 3 to separate the product 91 and the mold core 92 at the separation station 2B, and transfer the separated product 91 and mold core 92 to the product taking station 2C and the product placing station 2A respectively under the drive of the transplanting mechanism 2. Among them, the upper disassembly mechanism 3 and the lower disassembly mechanism 4 are respectively used to separate different fitting parts of the product 91 and the mold core 92.

[0056] Specifically, in this embodiment, the working process of the injection molded product and mold core separation mechanism is as follows: The transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product placing station 2A. After the injection mold finishes injection molding, a manipulator (not shown) takes out the to-be-separated part 9 from the injection mold and places it on the lower disassembly mechanism 4. The transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the separation station 2B, and then the upper disassembly mechanism 3 and the lower disassembly mechanism 4 work together to separate the product 91 and the mold core 92 in the to-be-separated part 9. After the separation is completed, the transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product taking station 2C. After the separated product 91 on the lower disassembly mechanism 4 is taken away by an operator (or a manipulator), the transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product placing station 2A, and the manipulator puts the separated mold core 92 on the lower disassembly mechanism 4 back into the injection mold for the next injection operation.

[0057] The injection molded product and mold core separation mechanism provided in this embodiment, by setting the transplanting mechanism 2, the upper disassembly mechanism 3, and the lower disassembly mechanism 4, uses the transplanting mechanism 2 to drive the lower disassembly mechanism 4 to switch positions among the product placing station 2A, the separation station 2B, and the product taking station 2C. When the lower disassembly mechanism 4 is located at the product placing station 2A, the lower disassembly mechanism 4 can receive the to-be-separated part 9. When the lower disassembly mechanism 4 is located at the separation station 2B, the lower disassembly mechanism 4 can cooperate with the upper disassembly mechanism 3 to separate the product 91 and the mold core 92 in the to-be-separated part 9. Then, the lower disassembly mechanism 4 can transfer the separated product 91 and mold core 92 to the product taking station 2C and the product placing station 2A respectively under the drive of the transplanting mechanism 2, so as to facilitate taking away the separated product 91 and mold core 92, thereby realizing the separation of the product 91 and the mold core 92 in the to-be-separated part 9. This injection molded product and mold core separation mechanism can greatly improve the separation efficiency of the product 91 and the mold core 92, thereby improving the production efficiency, reducing the production cost, and avoiding the operation risk of manual separation.

[0058] Further, as Figures 14 to 17 shown, in this embodiment, the product 91 is in a C-shaped structure, and one side of the product 91 has an opening 910 (in this embodiment, the product 91 is generally in a C-shaped tubular structure). The mold core 92 includes an insert block 921, two sliding blocks 922 slidably connected to the insert block 921 (i.e., the sliding blocks 922 can slide horizontally relative to the insert block 921), and two insert blocks 923 rotatably connected to the insert block 921 (i.e., the insert blocks 923 can rotate horizontally relative to the insert block 921). The insert block 921 is located inside the C-shaped product 91. The two insert blocks 923 are arranged on one side of the insert block 921 close to the opening 910, and the two insert blocks 923 are respectively fitted with the two ends of the product 91 at the opening 910. The two sliding blocks 922 are arranged on one side of the insert block 921 far from the opening 910, and the two sliding blocks 922 are respectively fitted with the bent parts on both sides of the product 91. The insert block 921 is fitted with the side of the product 91 far from the opening 910. Specifically, a border part 9210 is provided on the side of the insert block 921 far from the opening 910, and the border part 9210 is fitted with the side of the product 91 far from the opening 910.

[0059] The upper disassembly mechanism 3 is used to drive the two sliding blocks 922 to slide so that the sliding blocks 922 are separated from the product 91 (combined with Figure 7 , in this embodiment, the upper disassembly mechanism 3 specifically drives the two sliding blocks 922 to slide in the front-rear direction X). The lower disassembly mechanism 4 is used to drive the two insert blocks 923 to rotate so that the insert blocks 923 are separated from the product 91, and to drive the insert block 921 and the product 91 to move relative to each other so that the insert block 921 is separated from the product 91 (combined with Figure 7 , in this embodiment, the lower disassembly mechanism 4 specifically drives the insert block 921 and the product 91 to move relative to each other in the left-right direction Y).

[0060] Specifically, in this embodiment, the mold core 92 further includes two connecting rods 924. The two insert blocks 923 are respectively rotatably connected to the insert block 921 through the two connecting rods 924 (i.e., one end of the connecting rod 924 is rotatably connected to the insert block 921, and the insert block 923 is arranged on the connecting rod 924); the two ends of the product 91 at the opening 910 are actually respectively inserted into the two insert blocks 923. As Figure 15As shown in the figure, when separating the product 91 and the mold core 92, the upper disassembly mechanism 3 drives the two sliders 922 to move along the S11 direction and the S12 direction respectively, that is, the two sliders 922 move towards the inside, so that the two sliders 922 are disengaged from the product 91; on the one hand, the lower disassembly mechanism 4 drives the two inserts 923 to rotate along the S21 direction and the S22 direction respectively, that is, the two inserts 923 rotate towards the side away from the product 91 in opposite directions, so that the two inserts 923 are disengaged from the end of the product 91. On the other hand, the lower disassembly mechanism 4 drives the insert block 921 to move along the S3 direction (the product 91 remains stationary), so that the insert block 921 and the product 91 move relative to each other (of course, in other embodiments, the product 91 can also move and the insert block 921 remains stationary; or the insert 923 and the product 91 move in opposite directions respectively), so that the edge portion 9210 of the insert block 921 is disengaged from the product 91, and then the product 91 and the mold core 92 are completely separated.

[0061] Further, as Figures 1 to 5 and Figures 11 to 17 shown, in this embodiment, the upper disassembly mechanism 3 includes a telescopic driving device 31, two side pushing driving devices 32 and two first pin shafts 33. The two side pushing driving devices 32 are arranged oppositely, the two side pushing driving devices 32 are both connected to the telescopic driving device 31, and the two first pin shafts 33 are respectively arranged on the two side pushing driving devices 32. The telescopic driving device 31 is used to drive the two side pushing driving devices 32 and the two first pin shafts 33 to move up and down, so that the two first pin shafts 33 are respectively inserted into or separated from the two sliders 922; the two side pushing driving devices 32 are respectively used to drive the two first pin shafts 33 to move, so as to drive the two sliders 922 to slide.

[0062] Specifically, in this embodiment, second pin holes 9221 are respectively provided on the two sliders 922. After the lower disassembly mechanism 4 moves to directly below the upper disassembly mechanism 3, the telescopic driving device 31 drives the two side pushing driving devices 32 to move downward, and then drives the two first pin shafts 33 to move downward, so that the two first pin shafts 33 are respectively inserted into the second pin holes 9221 on the two sliders 922 from top to bottom; then the two side pushing driving devices 32 respectively drive the two first pin shafts 33 to move (specifically, the two first pin shafts 33 move horizontally towards the direction of approaching each other), so as to drive the two sliders 922 to move, and the two sliders 922 are disengaged from the product 91. In this embodiment, both the telescopic driving device 31 and the side pushing driving device 32 are cylinders; of course, in other embodiments, the telescopic driving device 31 and the side pushing driving device 32 can also be other linear driving mechanisms.

[0063] Further, as Figures 1 to 5 and Figures 11 to 17As shown, in this embodiment, the injection molded product and mold core separation mechanism further includes a lifting drive mechanism 5. The lifting drive mechanism 5 is arranged at the separation station 2B and is connected to the base 1. The lifting drive mechanism 5 is connected to the upper disassembly mechanism 3, and the lifting drive mechanism 5 is used to drive the upper disassembly mechanism 3 to move up and down.

[0064] Specifically, by setting the lifting drive mechanism 5, the lifting drive mechanism 5 is used to drive the upper disassembly mechanism 3 to move up and down. Before the lower disassembly mechanism 4 moves below the upper disassembly mechanism 3, the lifting drive mechanism 5 drives the upper disassembly mechanism 3 to move upward and retract to avoid interference and collision between the lower disassembly mechanism 4 and the upper disassembly mechanism 3 during the movement. After the lower disassembly mechanism 4 moves below the upper disassembly mechanism 3, the lifting drive mechanism 5 then drives the upper disassembly mechanism 3 to move downward, so that the upper disassembly mechanism 3 can approach or contact the lower disassembly mechanism 4, so that the upper disassembly mechanism 3 can perform the separation work.

[0065] Furthermore, as Figures 1 to 5 shown, in this embodiment, the lifting drive mechanism 5 includes a lifting drive device 51, a first telescopic bracket 52, and a gantry-shaped fixed bracket 53. The fixed bracket 53 is arranged on the base 1 (specifically, the fixed bracket 53 is arranged on the electric control cabinet 11). The lifting drive device 51 is fixedly arranged on the fixed bracket 53. The first telescopic bracket 52 is slidably connected to the fixed bracket 53. The upper disassembly mechanism 3 is connected to the first telescopic bracket 52. The lifting drive device 51 is connected to the first telescopic bracket 52. The lifting drive device 51 is used to drive the first telescopic bracket 52 to move up and down, and then drive the upper disassembly mechanism 3 to move up and down. In this embodiment, the lifting drive device 51 is a cylinder. Of course, in other embodiments, the lifting drive device 51 can also be other linear drive mechanisms.

[0066] Specifically, in this embodiment, the first telescopic bracket 52 includes a connecting plate 521 and a plurality of guide rods 522. The plurality of guide rods 522 are all slidably connected to the fixed bracket 53. The bottom ends of the plurality of guide rods 522 are all connected to the connecting plate 521. The guide rods 522 can play a guiding role in the up and down movement of the connecting plate 521. The lifting drive device 51 is connected to the connecting plate 521. The upper disassembly mechanism 3 is connected to the connecting plate 521. The lifting drive device 51 can drive the connecting plate 521 to move up and down, and then drive the upper disassembly mechanism 3 to move up and down.

[0067] Furthermore, as Figures 1 to 5 and Figures 11 to 13As shown, in this embodiment, the upper disassembly mechanism 3 further includes a bottom plate 34, a limit block 35, a second telescopic bracket 36, and a plurality of support rods 37. Both the bottom plate 34 and the limit block 35 are located at the bottom of the upper disassembly mechanism 3. The telescopic driving device 31 is fixedly connected to the connecting plate 521, and the telescopic driving device 31 is connected to the second telescopic bracket 36. The limit block 35 and the two side pushing driving devices 32 are both connected to the second telescopic bracket 36. The telescopic driving device 31 can drive the second telescopic bracket 36 to move up and down, thereby driving the limit block 35 and the two side pushing driving devices 32 to move up and down. The bottom plate 34 is fixedly connected to the connecting plate 521 through a plurality of support rods 37, that is, the top end of each support rod 37 is fixedly connected to the connecting plate 521, and the bottom end of each support rod 37 is fixedly connected to the bottom plate 34. When the lifting driving mechanism 5 drives the upper disassembly mechanism 3 to move downward, the bottom plate 34 can abut against the lower disassembly mechanism 4 (specifically, abut against the upper plate 441). When the telescopic driving device 31 drives the limit block 35 to move downward, the limit block 35 can abut against the mold core 92 (specifically, abut against the insert block 921).

[0068] Specifically, in this embodiment, after the lower disassembly mechanism 4 moves below the upper disassembly mechanism 3, first, the lifting driving mechanism 5 drives the upper disassembly mechanism 3 to move downward. After the upper disassembly mechanism 3 moves downward for a certain distance, the bottom plate 34 abuts against the lower disassembly mechanism 4, that is, at this time, the lifting driving mechanism 5 and the lower disassembly mechanism 4 reach the descent position, and the lifting driving mechanism 5 stops operating. Since the bottom plate 34 abuts against the lower disassembly mechanism 4, the lower disassembly mechanism 4 can support the upper disassembly mechanism 3, so that the upper disassembly mechanism 3 can perform the separation work more stably. Then, the telescopic driving device 31 drives the second telescopic bracket 36 to move downward, and drives the two side pushing driving devices 32, the two first pin shafts 33, and the limit block 35 to move downward. After moving downward for a certain distance, the limit block 35 abuts against the mold core 92, and at the same time, the two first pin shafts 33 are respectively inserted into the two sliders 922, that is, the first pin shafts 33 and the limit block 35 reach the descent position, and the telescopic driving device 31 stops operating. Since the limit block 35 abuts against the mold core 92, the precise positioning of the upper disassembly mechanism 3 and the mold core 92 is realized, ensuring that the first pin shaft 33 can be inserted into the second pin hole 9221 on the slider 922, and the limit block 35 can play a certain role in fixing the mold core 92, preventing the position of the mold core 92 from shifting during the separation process.

[0069] Further, as Figures 1 to 10 and Figures 14 to 17As shown, in this embodiment, the lower disassembly mechanism 4 includes a first driving device 41, a transmission assembly 42, a second driving device 43, a slide plate assembly 44, and two second pin shafts 45. The two second pin shafts 45 are respectively used for plugging into two insertion blocks 923. The first driving device 41 is simultaneously connected to the two second pin shafts 45 through the transmission assembly 42. The first driving device 41 is used to drive the two second pin shafts 45 to rotate in opposite directions simultaneously, so as to drive the two insertion blocks 923 to rotate. The slide plate assembly 44 is used to place the part to be separated 9 (that is, the part to be separated 9 is placed on the slide plate assembly 44). The second driving device 43 is connected to the slide plate assembly 44; the second driving device 43 is used to drive the slide plate assembly 44 to move, so as to drive the insert block 921 and the product 91 to move relative to each other.

[0070] Specifically, in this embodiment, third pin holes 9231 are respectively provided on the two insertion blocks 923. After the part to be separated 9 is placed on the slide plate assembly 44, the two second pin shafts 45 are just inserted into the third pin holes 9231 on the two insertion blocks 923 from bottom to top; then the first driving device 41 drives the two second pin shafts 45 to rotate in opposite directions simultaneously through the transmission assembly 42, thereby driving the two insertion blocks 923 to rotate, so that the two insertion blocks 923 are disengaged from the end of the product 91.

[0071] In this embodiment, the transmission assembly 42 includes a toothed plate 421, two gears 422, two shaft rods 423, and two rotating rods 424. The first driving device 41 is connected to the toothed plate 421. The toothed plate 421 meshes with one of the gears 422 (the toothed plate 421 is provided with a plurality of teeth, and the teeth on the toothed plate 421 mesh with the gear 422). The two gears 422 mesh with each other. The two shaft rods 423 are respectively connected to the two gears 422 (in this embodiment, the two shaft rods 423 are respectively sleeved in the two gears 422). The two rotating rods 424 are respectively connected to the two shaft rods 423. The two second pin shafts 45 are respectively arranged on the two rotating rods 424 (specifically, one end of the rotating rod 424 is fixedly connected to a shaft rod 423, and the second pin shaft 45 is arranged at the other end of the rotating rod 424). When the first driving device 41 drives the toothed plate 421 to move, the toothed plate 421 drives one of the gears 422 to rotate. Since the two gears 422 mesh with each other, the other gear 422 is driven to rotate synchronously in the opposite direction, and then the two shaft rods 423, the two rotating rods 424, and the two second pin shafts 45 are driven to rotate in opposite directions simultaneously. With such a setting, the linear motion of the first driving device 41 can be converted into the synchronous reverse rotation of the two second pin shafts 45. In this embodiment, the first driving device 41 is an electric cylinder; in other embodiments, the first driving device 41 can also be other linear driving mechanisms. Of course, in other embodiments, the transmission assembly 42 can also be in other structural forms.

[0072] Further, asFigures 1 to 10 and Figures 14 to 17 As shown in Figures 14 to 17 , in this embodiment, the skateboard assembly 44 includes an upper plate 441 and a lower plate 442. The upper plate 441 is located above the lower plate 442, and the width of the upper plate 441 is smaller than that of the lower plate 442. The upper plate 441 is used to place the product 91, and the lower plate 442 is used to place the insert 921; the second driving device 43 is connected to the upper plate 441 or the lower plate 442, and the second driving device 43 is used to drive the upper plate 441 or the lower plate 442 to move, so that the upper plate 441 and the lower plate 442 move relative to each other, thereby driving the insert 921 and the product 91 to move relative to each other.

[0073] Specifically, in this embodiment, the second driving device 43 is connected to the lower plate 442, and the second driving device 43 is used to drive the lower plate 442 to move, and the upper plate 441 is fixed (of course, in other embodiments, it can also be that the second driving device 43 is connected to the upper plate 441, and the second driving device 43 is used to drive the upper plate 441 to move, and the lower plate 442 is fixed; or, the second driving device 43 is connected to both the upper plate 441 and the lower plate 442 at the same time, and the second driving device 43 is used to drive the upper plate 441 and the lower plate 442 to move in opposite directions at the same time). In this embodiment, when both the slider 922 and the insert block 923 are disengaged from the product 91, the second driving device 43 drives the lower plate 442 to move (as Figure 8 shown, the second driving device 43 drives the lower plate 442 to move along the Y1 direction), so that the upper plate 441 and the lower plate 442 move relative to each other. Since the product 91 is horizontally fixed on the upper plate 441 and the insert 921 is horizontally fixed on the lower plate 442 at this time, when the upper plate 441 and the lower plate 442 move relative to each other, it will drive the insert 921 and the product 91 to move relative to each other, thereby disengaging the insert 921 and the product 91. In this embodiment, the second driving device 43 is a cylinder; in other embodiments, the second driving device 43 can also be other linear driving mechanisms.

[0074] Furthermore, as Figures 1 to 10 and Figures 14 to 17 shown, in this embodiment, the upper surface of the upper plate 441 is provided with an arc-shaped limit groove 4411 for placing the product 91. The arc-shaped limit groove 4411 is arranged in imitation of the product 91, and a notch 4412 is provided at the position of the upper plate 441 corresponding to the insert 921; a positioning pin 443 for inserting into the insert 921 is provided on the lower plate 442.

[0075] Specifically, in this embodiment, a first pin hole 9211 is provided on the insert block 921. After the part 9 to be separated is placed on the slide plate assembly 44, the product 91 is located in the arc-shaped limiting groove 4411 on the upper plate 441, the insert block 921 is located on the lower plate 442, and the insert block 921 is located in the notch 4412. At the same time, the positioning pin 443 is inserted into the first pin hole 9211 on the insert block 921. By providing the arc-shaped limiting groove 4411, the notch 4412 and the positioning pin 443, not only can the accurate positioning of the product 91 and the mold core 92 be realized, but also the product 91 and the mold core 92 can be horizontally fixed on the upper plate 441 and the lower plate 442 respectively, which is convenient for subsequent separation of the two.

[0076] An arc-shaped avoidance groove 4421 is provided on the upper surface of the lower plate 442, and the arc-shaped avoidance groove 4421 is arranged corresponding to the rotation paths of the two insert blocks 923. The transmission assembly 42 and the two second pin shafts 45 are both located below the lower plate 442. An arc-shaped limiting hole 4422 for the two second pin shafts 45 to pass through is provided on the lower plate 442. The arc-shaped limiting hole 4422 is arranged corresponding to the rotation paths of the two second pin shafts 45, and the arc-shaped limiting hole 4422 corresponds to the arc-shaped avoidance groove 4421. Since the rotation paths of the insert blocks 923 and the second pin shafts 45 are both arc-shaped, the arc-shaped avoidance groove 4421 and the arc-shaped limiting hole 4422 are both arc-shaped structures.

[0077] Specifically, in this embodiment, by providing the arc-shaped avoidance groove 4421, the arc-shaped avoidance groove 4421 can avoid the insert block 923 and prevent the insert block 923 from interfering with the upper surface of the lower plate 442 during rotation; by providing the arc-shaped limiting hole 4422, on the one hand, the arc-shaped limiting hole 4422 can allow the second pin shaft 45 to pass through, so that the second pin shaft 45 can pass through the lower plate 442 and be inserted into the insert block 923, and on the other hand, the arc-shaped limiting hole 4422 can limit the second pin shaft 45, that is, the second pin shaft 45 can only rotate along the extension direction of the arc-shaped limiting hole 4422, avoiding the second pin shaft 45 from moving around during rotation.

[0078] Further, as Figures 1 to 10As shown in the figure, in this embodiment, the lower disassembly mechanism 4 further includes a support plate 46, and the first driving device 41, the transmission assembly 42, the second driving device 43 and the slide plate assembly 44 are all arranged on the support plate 46; the support plate 46 is connected to the transplanting mechanism 2. Among them, the upper plate 441 is fixedly connected to the support plate 46, the lower plate 442 is slidably connected to the support plate 46 through a first slide rail assembly (not labeled in the figure), and the second driving device 43 is fixedly connected to the support plate 46; both the first driving device 41 and the transmission assembly 42 are connected to the lower plate 442, and the first driving device 41 is slidably connected to the support plate 46 through a second slide rail assembly (not shown in the figure), that is, when the second driving device 43 drives the lower plate 442 to move, the first driving device 41 and the transmission assembly 42 will also move together with the lower plate 442.

[0079] Further, as Figures 1 to 6 shown, in this embodiment, the transplanting mechanism 2 includes a linear guide rail module 21 (specifically, the linear guide rail module 21 includes a linear guide rail and a servo motor connected to the linear guide rail, and the servo motor is used to provide power. For the structure of the linear guide rail module 21, reference can be made to the prior art and will not be elaborated here), a slider guide rail assembly 22 and a carrier plate 23. The linear guide rail module 21 and the slider guide rail assembly 22 both extend along the front-rear direction X, the slider guide rail assembly 22 is arranged on the left and right sides of the linear guide rail module 21, and the carrier plate 23 is connected to both the linear guide rail module 21 and the slider guide rail assemblies 22 on the left and right sides at the same time; the lower disassembly mechanism 4 is arranged on the carrier plate 23 (specifically, the support plate 46 in the lower disassembly mechanism 4 is arranged on the carrier plate 23). The linear guide rail module 21 is used to drive the carrier plate 23 to move, and further drive the lower disassembly mechanism 4 to move; the slider guide rail assembly 22 is used to support and guide the carrier plate 23 and disperse the force, so that the carrier plate 23 and the lower disassembly mechanism 4 can move more stably. Of course, in other embodiments, the transplanting mechanism 2 can also be other linear driving mechanisms.

[0080] Further, as Figures 1 to 6 shown, in this embodiment, the base 1 includes an electric control cabinet 11 and a support frame 12, and the support frame 12 is located above the electric control cabinet 11 and is connected to the electric control cabinet 11; the support frame 12 is arranged close to the product taking station 2C. The transplanting mechanism 2 and the lifting driving mechanism 5 are both arranged on the electric control cabinet 11. The electric control cabinet 11 is used to support the weight of the whole mechanism, and various electrical components can be installed and arranged in the electric control cabinet 11. A touch screen 13 and control buttons (not labeled in the figure) are arranged on the support frame 12, which are used to display the working state of the injection product and the mold core separation mechanism, equipment abnormalities and control them. Safety light curtains 14 are arranged on both sides of the support frame 12, and the safety light curtains 14 are used to ensure the safety of the work (for example, when the safety light curtain 14 detects that an object enters the equipment, the equipment stops working); for the working principle of the safety light curtain 14, reference can be made to the prior art and will not be elaborated here.

[0081] Further, as Figures 1 to 7 shown, in this embodiment, the number of the upper disassembly mechanism 3 and the lower disassembly mechanism 4 is two respectively. The two upper disassembly mechanisms 3 are arranged side by side left and right, and the two lower disassembly mechanisms 4 are arranged side by side left and right. When the two lower disassembly mechanisms 4 move to the separation station 2B, the two lower disassembly mechanisms 4 respectively correspond to the two upper disassembly mechanisms 3 one by one up and down. That is, the two upper disassembly mechanisms 3 and the two lower disassembly mechanisms 4 are divided into two groups, each group includes an upper disassembly mechanism 3 and a lower disassembly mechanism 4. The upper disassembly mechanism 3 and the lower disassembly mechanism 4 in each group cooperate to separate the product 91 and the mold core 92 in a to-be-separated part 9. That is, the injection-molded product and mold core separation mechanism can separate two to-be-separated parts 9 at the same time to improve the working efficiency.

[0082] The working process of the injection-molded product and mold core separation mechanism is as follows:

[0083] (1) The transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product placing station 2A. After the injection mold finishes injection molding, the manipulator takes out the to-be-separated part 9 from the injection mold and places it on the lower disassembly mechanism 4, and the to-be-separated part 9 is positioned through the positioning mechanism (including structures such as the arc-shaped limiting groove 4411 and the positioning pin 443) on the lower disassembly mechanism 4. At this time, the product 91 is located in the arc-shaped limiting groove 4411 on the upper plate 441, the insert block 921 is located on the lower plate 442, and the insert block 921 is located in the notch 4412. At the same time, the positioning pin 443 is inserted into the first pin hole 9211 on the insert block 921, and the second pin shaft 45 is inserted into the insert block 923.

[0084] (2) The transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the separation station 2B, so that the lower disassembly mechanism 4 is located directly below the upper disassembly mechanism 3. At this time, there is a certain distance between the upper disassembly mechanism 3 and the lower disassembly mechanism 4 up and down.

[0085] (3) The lifting drive mechanism 5 drives the upper disassembly mechanism 3 to move downward until the bottom plate 34 in the upper disassembly mechanism 3 abuts against the upper plate 441 in the lower disassembly mechanism 4, and then the lifting drive mechanism 5 stops operating.

[0086] (4) The telescopic drive device 31 in the upper disassembly mechanism 3 drives the two side push drive devices 32, the two first pin shafts 33 and the limit block 35 to move downward together. When it descends a certain distance, the limit block 35 abuts against the mold core 92, and at the same time, the two first pin shafts 33 are respectively inserted into the two sliders 922, that is, the first pin shaft 33 and the limit block 35 descend in place, and the telescopic drive device 31 stops operating.

[0087] (5) The two side push driving devices 32 in the upper disassembly mechanism 3 respectively drive the two first pin shafts 33 to move (specifically, the two first pin shafts 33 move horizontally towards the direction of approaching each other), thereby driving the two sliders 922 to move, so that the two sliders 922 are disengaged from the product 91. After the two sliders 922 are disengaged from the product 91, the telescopic driving device 31 in the upper disassembly mechanism 3 drives the two side push driving devices 32, the two first pin shafts 33 and the limit block 35 to move upward and retract together, so that the first pin shaft 33 is separated from the slider 922.

[0088] (6) The first driving device 41 in the lower disassembly mechanism 4 drives the two second pin shafts 45 to rotate simultaneously in opposite directions through the transmission assembly 42, thereby driving the two embedding blocks 923 to rotate, so that the two embedding blocks 923 are disengaged from the end of the product 91 (specifically, the first driving device 41 drives the toothed plate 421 to move, the toothed plate 421 drives one of the gears 422 to rotate, and since the two gears 422 are meshed with each other, the other gear 422 is driven to rotate synchronously in the opposite direction, and then the two shaft rods 423, the two rotating rods 424 and the two second pin shafts 45 are driven to rotate simultaneously in opposite directions).

[0089] (7) The lifting driving mechanism 5 drives the upper disassembly mechanism 3 to move upward and retract, so that the bottom plate 34 in the upper disassembly mechanism 3 is separated from the upper plate 441 in the lower disassembly mechanism 4.

[0090] (8) The second driving device 43 in the lower disassembly mechanism 4 drives the lower plate 442 to move, so that the upper plate 441 and the lower plate 442 move relatively. Since the product 91 is horizontally fixed on the upper plate 441 and the insert block 921 is horizontally fixed on the lower plate 442 at this time, after the upper plate 441 and the lower plate 442 move relatively, it will drive the insert block 921 and the product 91 to move relatively, and then the insert block 921 and the product 91 are disengaged; thus, the product 91 and the mold core 92 are completely separated.

[0091] (9) The transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product taking station 2C, and the separated product 91 on the lower disassembly mechanism 4 is taken away by manual (or manipulator).

[0092] (10) After the product 91 is taken, the start button is pressed, and the second driving device 43 in the lower disassembly mechanism 4 drives the lower plate 442 to reset. Then the transplanting mechanism 2 drives the lower disassembly mechanism 4 to move to the product placing station 2A, and the manipulator puts the separated mold core 92 on the lower disassembly mechanism 4 back into the injection mold for the next injection operation.

[0093] The injection molding product and mold core separation mechanism provided in this embodiment, by arranging the transplanting mechanism 2, the upper disassembly mechanism 3 and the lower disassembly mechanism 4, uses the transplanting mechanism 2 to drive the lower disassembly mechanism 4 to switch positions among the product placing station 2A, the separation station 2B and the product taking station 2C; when the lower disassembly mechanism 4 is located at the product placing station 2A, the lower disassembly mechanism 4 can receive the part to be separated 9; when the lower disassembly mechanism 4 is located at the separation station 2B, the lower disassembly mechanism 4 can cooperate with the upper disassembly mechanism 3 to separate the product 91 and the mold core 92 in the part to be separated 9; then, the lower disassembly mechanism 4 can transfer the separated product 91 and mold core 92 to the product taking station 2C and the product placing station 2A respectively under the drive of the transplanting mechanism 2, so as to facilitate taking away the separated product 91 and mold core 92, thereby realizing the separation of the product 91 and the mold core 92 in the part to be separated 9. This injection molding product and mold core separation mechanism can greatly improve the separation efficiency of the product 91 and the mold core 92, thereby improving the production efficiency, reducing the production cost, and avoiding the operation risk of manual separation.

[0094] Meanwhile, through special structural designs for the upper disassembly mechanism 3 and the lower disassembly mechanism 4, the complete separation of the product 91 and the mold core 92 in the part to be separated 9 can be achieved.
