Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a rotary two-color mold for an automobile ceiling handle. Background Art

[0002] A two-color mold means that two plastic materials are injection-molded on the same injection molding machine, formed in two times, but the product is demolded only once. Generally, this molding process is also called two-material injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. As shown in the attached Figure 1 For the ceiling handle of a high-class automobile, the middle part of the handle, that is, the hand-gripping part, is wrapped with soft rubber around the hard rubber for 360 degrees. The appearance requirement is extremely high. The parting line segment difference should be uniform and controlled within 0.02 mm. In addition, the product surface should be smooth without shrink marks, air streaks, bright marks, color difference, etc. This shows the high requirement for the mold accuracy. This kind of ceiling handle is neither suitable for using a rubber-coated mold nor can it be made according to the traditional rotary two-color mold because the accuracy of the rubber-coated mold cannot meet the requirements; while the traditional rotary two-color mold cannot achieve 360-degree wrapping of soft rubber for the fixed and moving molds. The structures of traditional two-color molds are that the two fixed mold cavities are different, while the two moving mold cavities are exactly the same. To achieve 360-degree wrapping of soft rubber, the injection-molded product has to be lifted and then flipped 180 degrees, or some two-color molds rotate and flip the entire lower mold by 180 degrees to achieve 360-degree wrapping. However, this structural design adds great difficulty to the mold itself, has a high cost, and also prolongs the product injection time. Summary of the Utility Model

Specific embodiments

[0026] The following uses specific specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Please refer to the attached Figure 1-3 As shown, a rotary two-color mold for an automotive ceiling handle is used for injection molding the handle shown in the attached Figure 1 In the figure. First, the overall shape of the handle needs to be injection molded with the hard plastic material PP. Second, the middle part of the grip is injection molded and coated with the soft plastic material TEPP. The rotary two-color mold includes an A plate 10, a B plate 20, and a bottom plate 30. A fixed mold core 40 and a moving mold core 50 for mold clamping cooperation are respectively provided in the A plate 10 and the B plate 20. A square iron 60 is provided between the B plate 20 and the bottom plate 30. The square iron 60 is used to support the B plate 20 and the A plate 10 during mold clamping. A guiding column 100 is provided on the square iron 60. The guiding column 100 sequentially passes through the guiding holes (not shown in the drawings) on the B plate 20 and the A plate 10, so that the B plate 20 and the A plate 10 move up and down along the guiding column 100;

[0028] As shown in the attached Figure 3As shown, the fixed part of the fixed mold core 40 remains stationary. There are two different fixed mold cavities 41 and 42 on the fixed mold core 40. The fixed mold cavities 41 and 42 are used for injecting the upper half shape of the handle. One fixed mold cavity 41 is used for injecting the hard rubber of the handle shape, and the other fixed mold cavity 42 is used for injecting the soft rubber for covering the middle part of the handle. Among them, the diameter of the soft rubber part corresponding to the fixed mold cavity 42 is slightly larger than the diameter of the middle part of the fixed mold cavity 42 to adapt to the injection of the covering soft rubber.

[0029] Please refer to the appendix Figure 4 As shown, the moving mold core 50 in this embodiment adopts a split structure. The moving mold core 50 is composed of a positioning core 51 arranged on the B plate 20 and two independent inserts 52 vertically fixed on the square iron 60. The positioning core 51 can move up and down relative to the two independent inserts 52. There are two moving mold cavities one 511 and 512 on the positioning core 51 that correspond to the fixed mold cavities 41 and 42 up and down. The moving mold cavities one 511 and 512 only match the shapes at both ends of the handle. At the top of the two independent inserts 52, there are moving mold cavities two 521 and 522 with different sizes, and the moving mold cavities two 521 and 522 match the shape of the middle part (i.e., the hand-held part) of the handle. The moving mold cavity one 511 and the moving mold cavity two 521 cooperate to form a half shape of the handle when the mold is closed. The moving mold cavity two 521 corresponds to the fixed mold cavity 41, and the moving mold cavity two 522 corresponds to the fixed mold cavity 42, and the corresponding relationship remains unchanged.

[0030] There is an activity cavity 53 that runs through the positioning core 51 up and down. When the mold is closed, the independent insert 52 passes through the activity cavity 53 and cooperates with the positioning core 51 to form the moving mold core 50. At the same time, the moving mold cavity one and the moving mold cavity two cooperate with the fixed mold cavity 2 to form a hard rubber injection mold cavity and a soft rubber injection mold cavity for injecting the handle. Among them, the moving mold cavity one 511, the moving mold cavity two 521, and the fixed mold cavity 41 are used for injecting the hard rubber of the handle shape, and the moving mold cavity one 512, the moving mold cavity two 522, and the fixed mold cavity 42 are used for injecting the soft rubber for covering the middle part of the handle.

[0031] The moving mold core 50 adopts a split structure. The two independent inserts 52 remain stationary, and only the positioning core 51 is rotatably installed on the B plate 20. There is a driving mechanism 70 on the B plate 20 that is only used to drive the positioning core 51 to rotate 180°. Then, it drives the two moving mold cavities one 511 and 512 to rotate 180°, rotates the handle with the hard rubber injection completed by 180°, and then performs secondary mold closing to complete the injection of the soft rubber for covering the middle part of the handle.

[0032] Among them, injection holes (not shown in the drawings) are provided in the fixed mold cavities 41, 42, the first moving mold cavities 511, 512, and the second moving mold cavities 521, 522, so that the injection molding materials are discharged from the fixed mold cavities 41, 42 and the moving mold cavities respectively. Especially during soft rubber overmolding, the soft rubber can wrap the hard rubber 360°, improving the injection precision and surface smoothness of the product.

[0033] Please refer to the attached Figure 5 As shown, the driving mechanism 70 includes a rotating shaft 71 installed in the middle of the lower surface of the positioning core 51, a gear set 72 arranged on the rotating shaft 71, and an oil cylinder 73 fixed to the side surface of the B plate 20. The telescopic end of the oil cylinder 73 is connected with a rack 74 meshing with the gear set 72. By driving the rack 74 to move back and forth through the oil cylinder 73, the positioning core 51 is driven to rotate 180°. Only when the mold is opened and the A plate and the B plate 20 move upward, and the two independent inserts 52 withdraw from the moving mold core 50, can the positioning core 51 be driven to rotate. After rotating 180°, the two first moving mold cavities 511, 512 are still respectively aligned with the two independent inserts 52 after exchanging positions, and a complete cavity for hard rubber injection of the handle shape and soft rubber injection in the middle of the handle is still formed after the second mold closing.

[0034] In the above embodiment, preferably, a seat 75 for fixing the oil cylinder 73 and a connecting block 76 fixedly connected to the seat 75 are further provided on the B plate 20. The connecting block 76 is placed on the lower surface of the B plate 20, and a limit component for limiting the movement stroke of the rack 74 is provided on the connecting block 76. The limit component includes a first stroke groove 77 arranged on the connecting block 76 along the length direction of the rack 74, a pair of travel switches 78, and a positioning rod 79. The pair of travel switches 78 are respectively arranged at both ends of the first stroke groove 77. The travel switch 78 is similar to the function of a sensor. The positioning rod 79 is fixed on the rack 74 and placed in the first stroke groove 77. Specifically, when the oil cylinder 73 drives the rack 74 to move forward, the rack 74 drives the positioning core 51 to rotate through meshing with the gear set 72, and the positioning rod 79 also moves along the length direction in the first stroke groove 77. When the first stroke groove 77 touches the front travel switch 78, the oil cylinder 73 stops working, and the positioning core 51 just rotates 180°. The rotation angle of the positioning core 51 can be accurately improved through the pair of travel switches 78, ensuring that the first moving mold cavities 511, 512 and the second moving mold cavities 521, 522 are respectively aligned to form a cavity and guaranteeing the injection quality of the product.

[0035] The moving mold core 50 is circular, so that the moving mold core 50 can only rotate within the B plate 20, ensuring the stability and safety of the moving mold core 50 during the rotation process. At the same time, to improve the service life of the mold, a wear-resistant block 741 is further provided on one side surface of the rack 74.

[0036] In the above embodiments, preferably, protruding pressing feet 80 are provided on the circumference of the moving mold core 50, and an annular pressing block 81 is fixed on the upper surface of the B plate 20. The annular pressing block 81 is placed above the pressing feet 80 to limit the axial movement of the moving mold core 50. At the same time, it can not only ensure the normal rotation of the moving mold core 50, but also enable it to move together with the B plate 20 during the mold closing and mold opening processes of the A plate 10 and the B plate 20.

[0037] In order to further improve the production quality of the product and prevent obvious defects on the product surface, it is necessary to ensure that the accuracy of each rotation is 180°. Therefore, a semi-circular annular limiting groove is also opened on the moving mold core 50, and a limiting guide rod placed in the semi-circular annular limiting groove is fixed on the B plate 20. The limiting guide rod is fixed, so that the moving mold core 50 can only rotate 180° each time under the action of the limiting groove and the limiting rod.

[0038] Please refer to the attached Figure 6 As shown, a plurality of limiting pins 90 are also fixed on the lower surface of the B plate 20. A second stroke groove 91 corresponding to the limiting pins 90 and arranged in the vertical direction is provided in the square iron 60. The cap end of the limiting pin 90 is placed in the second stroke groove 91, and the mold opening distance is accurately controlled by the limiting pin 90 and the second stroke groove 91 to ensure that the independent insert 52 completely exits the movable cavity 53, so that the moving mold core 50 can rotate smoothly.

[0039] As shown in the attached Figure 7 As shown, a plurality of positioning blocks 110 are also provided on the upper surface of the square iron 60, and grooves corresponding to the positioning blocks 110 one by one are provided on the lower surface of the B plate 20.

[0040] As shown in the attached Figure 2 and the attached Figure 6 As shown, a buckle 120 is also provided on the A plate 10 and the B plate 20. The buckle 120 is used to control the sequence of mold closing and mold clamping of the A plate 10 and the B plate 20, avoid mutual interference, and ensure the yield and efficiency of injection molding production. The buckle 120 used in this embodiment is a common buckle 120 in existing two-color molds, and the specific structure will not be elaborated.

[0041] Working principle:

[0042] When the mold is closed for the first injection molding, as shown in the attached Figure 6 As shown, the lower surface of the B plate 20 contacts the upper surface of the square iron 60, and the fixed mold cavity 41 and the first moving mold cavity 511 and the second moving mold cavity 521 are used for injecting hard glue in the shape of a handle, and the handle hard glue injection molding is completed;

[0043] When the mold is opened for the first time, as shown in the attached Figure 7As shown in the figure, the mechanical movement of the trigger 120 causes the A plate 10 and the B plate 20 to move upward together, separating the lower surface of the B plate 20 from the square iron 60. At this time, the A plate 10 and the B plate 20 still adhere to each other, and the independent insert 52 gradually withdraws from the movable cavity 53. The opening distance of the B plate 20 is controlled by the limit pin 90 until the independent insert 52 completely withdraws from the movable cavity 53 or the positioning core 51;

[0044] During the second mold opening, as shown in the appendix Figure 8 As shown in the figure, the B plate 20 remains stationary, and the A plate 10 continues to move upward along the guide post 100 relative to the B plate 20 to complete the second mold opening, exposing the moving mold core 50 and the hard rubber injection molded handle on the moving mold core 50. At this time, the hard rubber injection molded handles are respectively aligned with the fixed mold cavity 41 and the moving mold cavity two 521. Then, the oil cylinder 73 drives the positioning core 51 to rotate 180°, so that the hard rubber injection molded handle on the positioning core 51 rotates 180° from the hard rubber injection molded cavity to the soft rubber injection molded cavity, that is, after rotation, it is respectively aligned with the fixed mold cavity 42 and the moving mold cavity two 522 up and down;

[0045] Then the A plate 10 moves downward to complete the mold closing with the B plate 20. The A plate 10 and the B plate 20 then move downward together until the B plate 20 contacts the surface of the square iron 60 to complete the mold closing of the entire two-color mold. During the downward movement of the B plate 20, the square iron 60 gradually inserts into the movable cavity 53 and cooperates with the positioning core 51 to form a complete moving mold core 50. The moving mold cavity one 512 and the moving mold cavity two 522 cooperate with the fixed mold cavity 42 to form a soft rubber injection molded cavity, and fix the hard rubber injection molded handle in the soft rubber injection molded cavity during mold closing. Then, only the middle part of the fixed mold cavity 42 and the moving mold cavity two 522 inject glue to realize 360° coated soft rubber injection for the middle part of the handle;

[0046] During the soft rubber coated injection molding, the hard rubber injection molded cavity on the other side is also performing the above-mentioned hard rubber injection molding of the handle at the same time, maximizing the shortening of the product production cycle and improving production efficiency.

[0047] The two-color mold of the present utility model only needs to rotate other parts of the moving mold core 180° while ensuring that two separate inserts with inconsistent glue positions on the moving mold core 50 remain stationary, and the fixed mold cavity and the moving mold cavity inject glue at the same time, which can realize synchronous, fast and 360° coated injection molding of soft and hard rubber to produce high-quality products, without lifting and flipping the injection molded product, greatly reducing the design difficulty of the two-color mold, and achieving a material saving rate of more than 50% and a reduction in equipment investment cost.

[0048] The above-described embodiments merely represent the specific implementation manners of the present utility model. The technical solution of the present utility model can not only be used for injection molding the car roof handle, but can also be used for double-shot injection molding of other products by simply changing the shape of the cavity. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.

[0049] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.
