For example, in the home environment, for items with metal structures, in order to ensure safety, it is necessary to add a layer of plastic structure on the outside of the metal; in industry, coating metal with colloid can reduce noise, increase friction, etc. In life, such as mobile phone cases, it is necessary to set a metal part inside the plastic mobile phone case to adsorb the mobile phone on the magnetic part. For example, if you need to use a mobile phone for navigation while driving, by setting a metal part inside the mobile phone case, the mobile phone can be directly adsorbed on the mobile phone holder of the magnetic part.

One method is to leave space for fixing the metal parts or magnetic parts, and then use glue to fully cover the metal parts or magnetic parts after fixing. Another method is to use multiple injection molding to wrap the metal parts or magnetic parts. However, this method does not inject the reserved position for fixing, and also requires special glue filling for the fixing position, which has high production costs and long production processes.

In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present utility model will not be described separately.

[0031] like Figure 1 and Figure 2As shown, the utility model discloses an integrated molding full-cover injection mold, including an upper mold component and a lower mold component B arranged relatively to each other, the lower mold component B is provided with a sliding component A, a second slider 13, a first driving member 1 and a second driving member 2, the upper mold component and the lower mold component B are molded together to form a molding cavity 43 for accommodating a covering member 9 and injecting plastic material, the sliding component A is connected to the first driving member 1 and is driven by the first driving member 1 to slide on the lower mold component B, the second driving member 2 drives the second slider 13 to move relative to the covering member 9 and abut against the covering member 9; the sliding component A includes a bottom plate slidably arranged on the lower mold component B, a fixed needle plate 5 and a first slider 8 arranged on the upper part of the bottom plate, the first slider 8 is slidably arranged on the bottom plate, a plurality of fixing members 3 are arranged on the upper part of the fixed needle plate 5, and the fixing members 3 can move relative to the covering member 9 and abut against the covering member 9. The injection mold provided by the embodiment of the utility model can control the sliding assembly A through the first driving member 1, so that the fixing member 3 moves relative to the covering member 9 and abuts against the covering member 9, and achieves a supporting effect on the covering member 9, and drives the second slider 13 through the second driving member 2, so that the second slider 13 moves relative to the covering member 9 and abuts against the covering member 9, and achieves circumferential limitation on the covering member 9, and the injection molding process is started after the support and limitation of the covering member 9 are completed. After the injection molding process is completed, the fixing member 3 and the second slider 13 are driven by the first driving member 1 and the second driving member 2 to release the support and limitation of the covering member 9. The entire supporting and fixing process is simple to operate, and the supporting effect and circumferential limitation are carried out at the same time, and the covering member 9 can be fixed and limited in the molding cavity 43, and there will be no displacement during the injection molding process, so that the thickness of the injected plastic material covering the metal member is evenly distributed, and the molding product effect is good.

[0032] Specifically, in one embodiment of the utility model, the lower mold assembly B is further provided with a push plate 4, which is connected to the second driving member 2 and driven by the second driving member 2, so that the push plate 4 moves relative to the upper mold assembly. In specific applications, the push plate 4 is provided with a second sliding groove 41 for accommodating the second slider 13. The second slider 13 is slidably arranged in the second sliding groove 41 and moves relative to the covering member 9 and abuts against the covering member 9, so as to achieve circumferential positioning of the covering member 9, so that the covering member 9 will not shift during the injection molding process. The second slider 13 can be arranged in pairs, such as two or four. When the second slider 13 is set to two, the connection line of the two second sliders 13 is set at 180°. When the second slider 13 is set to four, the four second sliders 13 are evenly distributed, and the relative angle between two adjacent second sliders 13 is 90°. The second slider 13 can also be set to other numbers, such as three or six, and are evenly distributed on the push plate 4. In a specific application, four second sliders 13 are arranged and evenly distributed on the push plate 4, and the covering part 9 is circumferentially limited on all sides at the same time. During the injection molding process, the circumferential relative position of the covering part 9 is limited, and the injection force generated during the injection molding process will not cause the covering part 9 to be displaced, thereby ensuring that the thickness of the injected plastic material remains consistent when wrapping the metal part.

[0033] refer to Figures 2 to 6 As shown, the first driving member 1 and the second driving member 2 are both configured as oil cylinders or air cylinders. Preferably, in this embodiment, the first driving member 1 and the second driving member 2 are both configured as oil cylinders, the bottom plate as a whole is configured as a rectangular parallelepiped structure, the first driving member 1 is connected to the bottom plate, and the bottom plate is controlled by the first driving member 1 to slide relative to the lower mold assembly B, and an auxiliary member is arranged at the end of the bottom plate. Preferably, auxiliary members 12 are arranged at both ends of the bottom plate 11, and the auxiliary members 12 are detachably arranged on the bottom plate 11, the first sliding block 8 is configured as a T-shaped structure, and a first mating surface 81 is arranged at the bottom of the first sliding block 8, and the auxiliary member 12 is provided with a first sliding groove 121, and the first sliding groove 121 corresponds to The first slider 8 is configured as a T-shaped structure, and the first sliding groove 121 includes a first sliding surface 122; when the first slider 8 is slidably disposed in the first sliding groove 121, the first mating surface 81 and the first sliding surface 122 are in contact and can slide relative to each other. Preferably, the first sliding surface 122 and the first mating surface 81 are both configured as inclined surfaces. Therefore, when the first sliding surface 122 and the second sliding surface 42 slide relative to each other, the relative distance between the top surface 82 of the first slider 8 and the bottom plate 11 changes, driving the relative distance between the fixed needle plate 5 and the bottom plate 11 to change, so that the fixing part 3 moves relative to the direction of the covering part 9 and abuts against the covering part 9, thereby supporting the covering part 9.

[0034] Specifically, a force plate 6 is arranged on the top of the fixed needle plate 5. The force plate 6 serves as an intermediate piece for transmitting force between the fixed needle plate 5 and the first slider 8. Therefore, it is arranged as a rectangular parallelepiped structure with a size comparable to that of the bottom plate 11. The two ends of the force plate 6 are respectively placed on the top surface 82 of the first slider 8. Driven by the first slider 8, the relative distance between the force plate 6 and the bottom plate 11 changes, thereby changing the distance of the fixed needle plate 5 as a whole (including the fixing member 3 and the force plate 6) relative to the bottom plate 11, further making the fixing member 3 relatively move relative to the covering member 9 and abut against the covering member 9, so as to achieve the bottom support effect of the fixing member 3 on the covering member 9. Preferably, the force plate 6 is detachably connected to the fixed needle plate 5, and the force plate 6 is provided with a plurality of avoidance holes 61 corresponding to the fixing member 3. The fixing member 3 is arranged on the fixed needle plate 5 and passes through the avoidance holes 61. The specific movement process of the sliding component A is as follows: when the first driving member 1 is pushed forward, the bottom plate 11 slides relative to the lower mold component B, and the first sliding surface 122 and the first matching surface 81 arranged on the inclined surface slide relative to each other, so that the relative distance between the top surface 82 of the first sliding block 8 and the bottom plate 11 becomes larger (that is, the top surface 82 of the first sliding block 8 moves toward the direction of the covering 9), driving the force-bearing plate 6 mounted on the top surface 82 to move toward the direction of the covering 9, and further driving the fixed needle plate 5 to move toward the direction of the covering 9, so that the fixing member 3 moves toward the covering 9 and abuts against the bottom of the covering 9, thereby achieving a supporting effect on the covering 9. After the injection molding process is completed, the first driving member 1 withdraws, the bottom plate 11 slides relative to the lower mold assembly B, and the first sliding surface 122 and the first matching surface 81 set on the inclined surface slide relative to each other, so that the relative distance between the top surface 82 of the first slider 8 and the bottom plate 11 becomes smaller (that is, the top surface 82 of the first slider 8 is away from the covering member 9). Under the action of gravity, the fixed needle plate 5 and the force plate 6 are away from the covering member 9, and the fixing member 3 set on the fixed needle plate 5 is synchronously away from and withdraws from the molding cavity 43, and loses support for the covering member 9; during the entire action process, the bottom plate 11 moves horizontally, and the fixed needle plate 5 and the force plate 6 move vertically relative to the molding cavity 43. The covering member 9 can be a metal member or a magnetic member of any shape. In this embodiment, the covering member 9 is set as a cylindrical metal member.

[0035] Specifically, the bottom plate 11 is further provided with a plurality of strip-shaped mounting holes 111, and the bottom plate 11 is arranged on the lower mold assembly B through the strip-shaped mounting holes 111, so as to ensure that the bottom plate 11 slides within a certain range relative to the lower mold assembly B. Preferably, step structures are provided on both sides of the auxiliary block, and stoppers 14 are provided at the step structures, and both ends of the force-bearing plate 6 are respectively limited by the stoppers 14, so as to prevent the force-bearing plate 6 from being separated from the top surface 82 during the sliding process of the first slider 8.

[0036] Specifically, a slot 7 is provided at the edge of the push plate 4, and the slot 7 includes a accommodating cavity 71 and a supporting portion 72. Correspondingly, a head 22 and a groove 21 are provided on the second driving member 2, and the width of the groove 21 corresponds to the thickness of the supporting portion 72. When the second driving member 2 and the push plate 4 are connected, the head 22 is accommodated in the accommodating cavity 71, and the groove 21 is clamped in the supporting portion 72; when the second driving member 2 is advanced or withdrawn, the supporting portion 72 transmits force to the push plate 4, so that the distance between the push plate 4 and the upper mold assembly changes, and the second slider 13 arranged on the push plate 4 is driven to move relative to the direction of the covered member 9 and abut against the covered member 9 at the same time, thereby realizing a circumferential limiting effect on the covered member 9.

[0037] Specifically, the second slider 13 is configured as a T-shaped structure, and a second mating surface 131 is provided on one end face of the second slider 13. The second slider 13 is completely accommodated in the second sliding groove 41, and corresponding to the second mating surface 131, the second sliding groove 41 is provided with a second mating surface 131. The second mating surface 131 and the second sliding surface 42 are in contact and slide relative to each other. Preferably, the second mating surface 131 and the second sliding surface 42 are both configured as inclined surfaces. Therefore, when the second sliding surface 42 and the second mating surface 131 slide relative to each other, the second slider 13 can be moved relative to the covering 9 and circumferentially fix the covering 9.

[0038] Specifically, the second slider 13 is also provided with a pushing column 132. In the present embodiment, the pushing column 132 is arranged at an end away from the second mating surface 131. When the second mating surface 131 and the second sliding surface 42 slide relative to each other, the pushing column 132 moves relative to the covering 9 and abuts against the covering 9, thereby limiting the circumferential position of the covering 9. Preferably, four second sliders 13 are provided, and are evenly distributed on the pushing plate 4 to achieve a stable circumferential fixed state. In a specific application, a through hole 44 is opened between the molding cavity 43 and the second sliding groove 41. The pushing column 132 passes through the through hole 44 and moves relative to the covering 9 and abuts against the covering 9 along the through hole 44. The through hole 44 is opened along the side wall of the molding cavity 43 and connects the second sliding groove 41 and the molding cavity 43. A mounting member 45 is also provided on the top of the push plate 4 , which can limit the second slider 13 in the second sliding groove 41 to ensure that the second slider 13 does not separate from the second sliding groove 41 , so that the push column 132 can only move along the through hole 44 relative to the covering member 9 . The circumferential positioning process of the push plate 4 with respect to the covering part 9 is as follows: when the second driving member 2 is pushed forward, the force is transmitted to the push plate 4 through the support part 72, and the push plate 4 moves upward relative to the upper mold assembly. During the movement, the second sliding surface 42 and the second matching surface 131 slide relative to each other, so that the push column 132 arranged on the other end surface of the second slider 13 moves along the through hole 44 toward the molding cavity 43 until it abuts against and fixes the covering part 9. The four evenly arranged second sliders 13 can make the circumferential fixing effect of the covering part 9 better; after the injection molding process is completed, the second driving member 2 withdraws, and the force is transmitted to the push plate 4 through the support part 72, and the push plate 4 moves downward relative to the upper mold assembly. During the movement, the second sliding surface 42 and the second matching surface 131 slide relative to each other, so that the push column 132 withdraws from the molding cavity 43. Preferably, in order to ensure uniform force, two second driving members 2 are provided and are correspondingly arranged on the corresponding outer side surfaces of the mold.

[0039] In another embodiment of the utility model, the second driving member 2 is directly connected to the second slider 13 and directly drives the second slider 13, so that the second slider 13 moves relative to the covering member 9 and abuts against the covering member 9, thereby realizing circumferential position limiting of the covering member 9. In a specific application, four second sliders 13 are provided, and four corresponding second driving members 2 are provided. When fixing the covering member 9, the four second driving members 2 are pushed forward at the same time, driving the four second sliders 13 to move relative to the covering member 9 at the same time, and abut against the side of the covering member 9, thereby realizing circumferential position limiting of the covering member 9.

[0040] The utility model also provides a vertical injection molding machine, which includes the above-mentioned integrated molding full-coverage injection mold, and is also provided with a pressure holding mechanism, which is connected to the computer system of the injection molding machine. The product molding process is as follows: before injection molding, the covering part 9 is supported and circumferentially limited by the fixing part 3 and the second slider 13, and the mold is closed after the support and limitation are completed to start the injection molding process. After the injection molding process is completed, the injected plastic material is cooled and solidified, and the support and circumferential limitation of the covering part 9 by the fixing part 3 and the second slider 13 are released. The pressure holding system starts to operate under the control of the computer system. During the pressure holding process, the melt in the material pipe is continuously injected into the molding cavity 43. Under the action of the pressure holding system, the continuously injected melt fills the aforementioned parts that have not been injected due to the support and circumferential limitation of the covering part 9 by the fixing part 3 and the second slider 13 on the one hand, and on the other hand, supplements the dimensional error of the injection molded part 10 due to the shrinkage of the product during the cooling process. After the injection molding is completed, the pressure is maintained to ensure the stability of the product size. In this embodiment, by directly maintaining pressure after injection molding, the metal parts or magnetic parts can be fully covered, the overall size of the product is stable, the quality is good, and it is integrated into one, and there is no need to perform steps such as glue filling for the product.

[0041] The utility model provides an integrated full-coverage injection mold and a vertical injection molding machine. Before injection molding, the covered part 9 is supported and circumferentially limited, and then the mold is closed for injection molding. After the injection molding is completed, the support and limitation of the covered part 9 are released, leaving a glue position for the second pressure-holding molding (that is, the support and limitation of the covered part 9 by the aforementioned fixing part 3 and the second slider 13 that are not injected, and the dimensional error of the injection-molded part 10 due to shrinkage during the cooling process). The pressure-holding system starts to operate under the control of the computer system to fill the uninjected positions and make up for the dimensional error; the utility model adopts a process of holding pressure immediately after the injection molding is completed for the covered part 9, which can form a product that fully wraps and covers metal parts or magnetic parts at one time. The product is evenly covered and has a good covering effect. There is no need to perform additional treatment such as glue filling on the fixed parts, which saves production costs and processes and shortens the production cycle; the design is highly applicable and can be used for comprehensive integrated molding and covering of covered parts 9 of different shapes.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
