DETAILED DESCRIPTION

[0031] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0034] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0035] The present application is further described below with reference to the accompanying drawings: like Figures 1 to 13 As shown, the present application provides a car spoiler mold, including a fixed mold 1 and a movable mold 2, a core 11 is arranged on the fixed mold 1, and a cavity 21 is arranged on the movable mold 2, the core 11 and the cavity 21 are suitable for combining with each other, and a molded part 3 is molded therebetween, after the cavity 21 and the core 11 are combined with each other, a parting line 311 is suitable for forming at the contact position between the cavity 21 and the core 11, in the production process of traditional automobile accessories, the parting line 311 is generally located at the junction of the appearance area 32 and the non-appearance area 31 of the molded part 3, when the mold is opened, affected by factors such as the tightness and precision of the combination of the cavity 21 and the core 11, a step flash phenomenon may occur, if the step flash phenomenon appears toward the appearance area 32 of the molded part 3, it will affect the aesthetics of the product.

[0036] Therefore, in order to solve the influence of the parting line 311 on the aesthetics of the product and avoid the occurrence of flash on the outer surface side of the molded part 3 which is easily observed, the combination position of the cavity 21 and the core 11 is optimized and adjusted in the present application so that the parting line 311 is located in the non-appearance area 31 of the molded part 3.

[0037] However, the adjustment of the parting line 311 will lead to new problems. Normally, as the parting line 311 moves toward the non-appearance area 31, the cavity 21 will gradually cover the molded part 3. The deeper the parting line 311 goes into the non-appearance area 31, the deeper the cavity 21 covers the molded part 3. Therefore, on the premise that at least part of the appearance area 32 of the molded part 3 is molded by the cavity 21, it is also necessary to ensure that the covered part of the structure of the molded part 3 is suitable for being separated from the state of being covered by the cavity 21 after shrinkage. Specifically, the parting line 311 can be designed to be slightly moved into the non-appearance area 31 so that the flash phenomenon is complete and only appears in the non-appearance area 31, so as to ensure the aesthetics of the molded part 3 and enable smooth demolding without deformation, strain or damage.

[0038] It can be understood that in the field of automotive interior and exterior technology, the non-appearance area 31 of the molded part 3 refers to the area that will be covered by the vehicle body or other decorations, and the appearance area 32 of the molded part 3 refers to the area that can be directly observed by the user after the molded part 3 is installed. In the present application, the cavity 21 is used to mold the appearance area 32, and the core 11 is used to mold the non-appearance area 31.

[0039] Among them, in order to enable the molded part 3 to follow the cavity 21 and separate from the core 11 during the mold opening process, a pick-up mechanism 4 is provided in the present application. The pick-up mechanism 4 is connected to the movable mold 2, and part of the structure of the pick-up mechanism 4 passes through the core 11 and extends to the cavity 21. When the movable mold 2 and the fixed mold 1 move away from each other, the pick-up mechanism 4 is suitable for following the movement of the movable mold 2 to enable the molded part 3 to follow the cavity 21 and synchronously separate from the core 11. It can be understood that the pick-up mechanism 4 cooperates with the cavity 21 to clamp the molded part 3 to ensure that the matching state between the molded part 3 and the cavity 21 remains unchanged until the molded part 3 is completely shrunk and can be separated from the covering influence of the cavity 21 for smooth demolding.

[0040] like Figure 2 In the illustrated embodiment, since automobile accessories are generally plate-like components, in order to facilitate mold opening and demolding, and to reduce the probability of the parting line 311 being observed, the parting line 311 is usually located on the peripheral edge of the molded part 3. Therefore, as the parting line 311 is adjusted and moved toward the non-appearance area 31, the appearance area 32 of the peripheral edge of the molded part 3 will be encapsulated and molded by the cavity 21.

[0041] Furthermore, the circumferential edge of the molded part 3 is configured as a rounded structure, and the protruding portion of the circumferential edge of the molded part 3 (the portion with the rounded structure) is encapsulated and molded by the cavity 21. The rounded structure applied to the edge of the automotive trim is more practical and aesthetically pleasing. At the same time, it can improve the smoothness of the molded part 3 from the cavity 21, reduce the difficulty of demolding, and reduce the probability of the edge being torn and damaged.

[0042] like Figure 1 , 3 In the embodiments shown in Figures 4 and 7, the removal mechanism 4 includes an ejector plate 41, a lifting assembly 42 and a distance rod assembly 43. The ejector plate 41 is arranged on the side of the fixed mold 1 away from the movable mold 2, and the lifting assembly 42 is arranged on the side of the ejector plate 41 close to the fixed mold 1. The lifting assembly 42 passes through the fixed mold 1 and extends to the cavity 21. The distance rod assembly 43 connects the movable mold 2 and the ejector plate 41.

[0043] The distance pull rod assembly 43 is suitable for moving the ejector plate 41 toward the movable mold 2 so that the lifting assembly 42 is close to the cavity 21. When the lifting assembly 42 is close to the cavity 21, the upper surface of the lifting assembly 42 can cooperate with the surface setting of the core 11 to form the molded part 3. The appearance defects caused by the combination of the lifting assembly 42 and the core 11 can be hidden in the non-appearance area 31 of the molded part 3.

[0044] The distance pull rod assembly 43 is suitable for moving the ejector plate 41 away from the movable mold 2 so that the lifting assembly 42 is away from the cavity 21. In the present application, the fixed mold 1 and the movable mold 2 cooperate along the direction of gravity. Therefore, after the lifting assembly 42 is away from the cavity 21, the bottom of the molded part 3 will lose support, and the molded part 3 in the cavity 21 can loosen under the influence of gravity, or even directly follow the lifting assembly 42 away from the cavity 21, thereby reducing the difficulty of demolding.

[0045] like Figure 3 and 4 In the illustrated embodiment, the length of the lifting assembly 42 is greater than the distance from the core 11 at the location where the lifting assembly 42 is set to the bottom of the fixed mold 1, so that the lifting assembly 42 is suitable for moving between the cavity 21 and the core 11 after being synchronously raised with the movable mold 2. The purpose of this design is to improve the mobility of the lifting assembly 42, reduce the structural interference between the lifting assembly 42 and the fixed mold 1, and ensure that sufficient space can be generated between the lifting assembly 42 and the cavity 21 to facilitate demolding of the molded part 3.

[0046] like Figure 8In the illustrated embodiment, the ejector plate 41 is disposed between the fixed mold 1 and the mold base 5. A guide column 51 is disposed on the mold base 5. The ejector plate 41 is suitable for sliding along the guide column 51. The guide column 51 is used to improve the stability of the movement of the ejector plate 41, so that the lifting force of the ejector assembly 42 on the molded part 3 and the clamping force formed between the ejector assembly 42 and the cavity 21 remain stable and consistent, thereby protecting the molded part 3 during the mold opening process.

[0047] like Figures 3 to 4 In the illustrated embodiment, the lifting assembly 42 includes a lift block 421 and a lift rod 422, a limiting groove 111 is provided on the core 11, a connecting channel 12 is provided in the fixed mold 1, the limiting groove 111 is suitable for accommodating the lift block 421, and the connecting channel 12 is suitable for accommodating the lift rod 422. The connecting channel 12 is suitable for limiting the entry of the lift block 421. It can also be simply understood that the diameter of the connecting channel 12 is smaller than the width of the limiting groove 111, so as to prevent the lift block 421 from accidentally entering the connecting channel 12 and causing damage to the fixed mold 1.

[0048] like Figures 3 to 4 In the embodiment shown, the top block 421 tends to shrink from the top to the bottom. Since the limiting groove 111 needs to accommodate the top block 421, the structure of the limiting groove 111 can also be configured to shrink from the top to the bottom. This design can reduce the difficulty of the top block 421 and the limiting groove 111 to connect with each other, reduce the probability of structural interference between the top block 421 and the limiting groove 111 during the descent process, and improve the operation stability.

[0049] like Figure 4 In the illustrated embodiment, the upper end of the push rod 422 is fixedly connected to the lower part of the push block 421, the push rod 422 is arranged along the moving direction of the movable mold 2, and the push rod 422 and the push block 421 are installed and combined from the side. Installing the push block 421 and the push rod 422 from the side can effectively reduce the difficulty of installation. At the same time, after the lifting assembly 42 rises with the fixed mold 1, the connection state and connection stability between the push rod 422 and the push block 421 can also be conveniently observed from the side.

[0050] like Fig. 9 In the illustrated embodiment, part of the lifting assembly 42 is configured such that the lower end of the ejector rod 422 is slidably and rotatably connected to the ejector plate 41, the sliding connection direction between the lower end of the ejector rod 422 and the ejector plate 41 is perpendicular to the moving direction of the movable mold 2, and the upper end of the ejector rod 422 is inclined in a direction away from the parting line 311. By providing a slide rail on the ejector plate 41, the lower end of the ejector rod 422 is rotatably matched with the slide rail and slides along the slide rail, so that the ejector rod 422 drives the ejector block 421 to lift in the inclined direction, so that the ejector block 421 gradually moves away from the cavity 21 during the lifting process, thereby reducing the structural interference with the molded part 3.

[0051] like Fig.10In the illustrated embodiment, the distance rod assembly 43 includes a driver 431 and a connecting rod 432. The driver 431 connects the fixed mold 1 and the ejector plate 41. The driver 431 is suitable for moving the ejector plate 41 closer to or farther away from the fixed mold 1. One end of the connecting rod 432 is connected to the ejector plate 41, and the other end of the connecting rod 432 is suitable for engaging with the movable mold 2 to limit the relative distance between the movable mold 2 and the ejector plate 41. The distance rod assembly 43 is used to maintain the relative position between the ejector plate 41 and the movable mold 2, so that the ejector plate 41 can move synchronously with the movable mold 2 relative to the fixed mold 1.

[0052] In some embodiments, the actuator 431 is a pneumatic cylinder.

[0053] like Fig.10 In the illustrated embodiment, a guide rail 22 is provided on the fixed mold 1, and a guide member 4321 is provided on the connecting rod 432. The guide member 4321 is suitable for moving along the guide rail 22. The guide member 4321 and the guide rail 22 can improve the activity stability of the connecting rod 432 and ensure the cooperation between the connecting rod 432 and the fixed mold 1.

[0054] like Figure 7 and 10 In the illustrated embodiment, the connecting rod 432 and the ejector plate 41 are hinged, and the guide rail 22 is slidably matched with the guide member 4321 on at least the side away from the fixed mold 1 to limit the connecting rod 432 from rotating away from the fixed mold 1. When the guide member 4321 is located in the guide rail 22, the guide rail 22 can play a fixing role to prevent the connecting rod 432 from rotating. It can be understood that a disengagement port can be provided at a certain position of the guide rail 22 to facilitate the disengagement of the guide member 4321, thereby allowing the connecting rod 432 to rotate. For example, when the movable mold 2 is raised to a position higher than the demolding position, the guide member 4321 will be exposed in the disengagement port. At this time, the connection between the connecting rod 432 and the movable mold 2 can be released, thereby releasing the spacing effect between the movable mold 2 and the fixed mold 1.

[0055] In some embodiments, a variety of different types of guide members 4321 can be set on the circumferential side of the connecting rod 432 to cooperate with the guide rail 22 for sliding. For example, a rectangular guide member 4321 and a cylindrical guide member 4321 are respectively set on both sides of the connecting rod 432 to cooperate with the guide rail 22, which can play an identification role and prevent the connecting rod 432 from being installed upside down.

[0056] like Fig.10 In the illustrated embodiment, a travel switch 44 is provided on the fixed mold 1 or the mold base 5 connected to the fixed mold 1. The travel switch 44 is suitable for sensing the height of the ejector plate 41. The travel switch 44 at a lower position can be used to confirm the matching position between the ejector block 421 and the core 11 to ensure that the ejector block 421 and the core 11 are not compressed or insufficiently combined. The travel switch 44 at a higher position can be used to confirm the demolding position of the molded part 3 to ensure that at this position, all positions of the molded part 3 can be smoothly separated from the cavity 21.

[0057] like Fig.11 In the illustrated embodiment, a lock head 23 is provided on the movable mold 2. The lock head 23 is suitable for telescopic movement in a direction perpendicular to the sliding direction of the connecting rod 432. The end of the connecting rod 432 is suitable for locking with the extended lock head 23. The lock head 23 is a pop-up design. The connecting rod 432 can press and pass through the lock head 23 during the process of rising with the ejector plate 41. The lock head 23 can pop out and limit the lowest descending position of the connecting rod 432 after the connecting rod 432 passes, so that the connecting rod 432 can rise with the movable mold 2.

[0058] like Fig.11 In the illustrated embodiment, the lock head 23 is retracted by providing a spring between the lock head 23 and the movable mold 2 .

[0059] like Figure 1 , 5 In the embodiments shown in Figures 6 and 7, a movable component 24 is provided on the movable mold 2, and the movable component 24 is suitable for cooperating with the core 11 to mold the molded part 3. A guide rod 13 is provided on the fixed mold 1, and the guide rod 13 is slidably connected with the movable component 24. The upper end of the guide rod 13 is inclined away from the cavity 21. When the movable mold 2 and the fixed mold 1 are away from each other, the guide rod 13 is suitable for moving the movable component 24 away from the cavity 21, thereby releasing the release between the movable component 24 and the molded part 3 and interfering with the demolding of the molded part 3.

[0060] like Fig.12 In the illustrated embodiment, a notch 33 is provided in a non-appearance area 31 of the molded part 3 on the side of the parting line 311 close to the core 11, and the movable component 24 is suitable for the molding notch 33. The movable direction of the movable component 24 at least matches the connecting extension direction of the notch 33, so that the movable component 24 can be detached along the notch 33, and it is not easy to cause damage to the structure of the molded part 3.

[0061] like Fig.13 In the illustrated embodiment, the movable component 24 includes a slider 241 and an elastic member 242. The elastic member 242 is disposed between the slider 241 and the movable mold 2. The elastic member 242 is suitable for pushing the slider 241 to move away from the cavity 21. The elastic member 242 needs to be set according to the angle between the slider 241, the guide rod 13 and the movable mold 2. If the guide rod 13 is difficult to smoothly push the slider 241 away from the cavity 21, the elastic member 242 can play an auxiliary role to help the slider 241 slide along the guide rod 13 and away from the cavity 21.

[0062] like Fig.12 and 13In the illustrated embodiment, a casting channel 2411 is provided in the slider 241. The casting channel 2411 converges at the notch 33 and is connected to the notch 33. The convergence of the casting channel 2411 can reduce the generation of casting waste at the notch 33, and makes it easier to cut off and separate the casting waste from the notch 33. At the same time, since the notch 33 serves multiple connecting, clamping and fixing functions, the requirements for the flatness and aesthetics of the appearance are relatively low. Setting the casting channel 2411 at the notch 33 can reduce the difficulty of subsequent processing.

[0063] The above describes the basic principles, main features and advantages of the present application. Technical personnel in this industry should understand that the present application is not limited to the above embodiments. The above embodiments and the specification only describe the principles of the present application.
