Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an injection mold for a hidden door handle. Background Technology

[0002] With the development of intelligent vehicles, hidden door handles are gradually becoming standard equipment on high-end models and are deeply integrated with keyless entry systems, bringing users a more convenient and ceremonial driving experience. Hidden door handles adopt a streamlined structure flush with the body, effectively reducing wind resistance and enhancing the overall aesthetics. They usually pop out automatically through electronic sensing, buttons, or touch control. Some models are also equipped with an ice-breaking mode and a mechanical emergency unlocking device to ensure reliability in extreme environments. This design not only enhances the sense of technology and futurism but also optimizes aerodynamic performance, which is especially significant for improving the range of electric vehicles.

[0003] Existing concealed door handle housings are generally injection molded using molds. However, existing concealed door handle housings require the forming of grooves inside the housing. Since the grooves need to be formed on the vertical inner wall, horizontal demolding is required. Due to the small space inside the housing, demolding using conventional injection molds is difficult. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an injection mold for a hidden door handle.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] An injection mold for concealing a door handle includes an upper mold plate, a lower mold plate, and a molding plate disposed on the upper mold plate and the lower mold plate;

[0007] The forming plates form a forming cavity for forming the handle housing, and the handle housing is spaced out with an installation groove. The installation groove forms a slot. The upper template is provided with a snap-on demolding structure. The snap-on demolding structure includes a first slider horizontally inserted on the upper template, a second slider slidably disposed on the first slider, a third slider slidably disposed on the second slider, and a driving unit for driving the first slider to slide.

[0008] The second slider is vertically inserted into the molding cavity, and the third slider is horizontally placed in the mounting groove. The driving unit drives the first slider to move horizontally, so that the second slider moves up and down, and drives the third slider to move closer to or away from the molding area of ​​the slot.

[0009] Preferably, the first slider has an inclined first groove, and the second slider has a first sliding protrusion. The first sliding protrusion is slidably disposed in the first groove. With the above improvement, the inclined first groove and the first sliding protrusion cooperate, and as the driving unit pushes the first slider to slide horizontally, the second slider is driven to slide up and down, so as to drive the third slider away from or close to the forming area of ​​the slot.

[0010] Preferably, the second slider has an inclined second groove and a second sliding protrusion. The second sliding protrusion is slidably disposed in the second groove. With the above improvement, the inclined second groove and the second sliding protrusion cooperate with each other. When the second slider slides up and down, the third slider will move away from or closer to the forming area of ​​the slot to achieve demolding.

[0011] Preferably, the molding plate forms a demolding groove for the second slider to slide, and the above improvements further enhance the stability of the second slider during the sliding process.

[0012] Preferably, a confirmation observation rod is connected to the first slider, and when the upper and lower mold plates are in the mold-closed state, the confirmation observation rod extends out of the upper mold plate. With the above improvement, when the upper and lower mold plates are in the mold-closed state, the confirmation observation rod will extend out of the upper mold plate to indicate that the upper and lower mold plates have been closed in place.

[0013] Preferably, the upper template forms a sliding channel for the confirmation observation rod to slide. Through the above improvements, the confirmation observation rod is guided, and the stability of the confirmation observation rod during the sliding process is improved.

[0014] Preferably, the upper template is provided with a wear-resistant plate, and the wear-resistant plate abuts against the upper surface of the first slider. Through the above improvements, the wear-resistant plate can not only guide the first slider and ensure its stability during the sliding process, but also reduce the frictional resistance between it and the first slider, thereby increasing the service life of the slider and the mold.

[0015] Preferably, the upper template is provided with a guide block, and the guide block is provided with a guide groove for the second slider to be inserted. Through the above improvement, the guide groove is used to guide the second slider to ensure the stability of the second slider during the up and down sliding process.

[0016] Preferably, the upper template is provided with several snap-on demolding structures. Through the above improvements, multiple handle shells can be formed at one time to improve molding efficiency.

[0017] Preferably, the third slider constitutes a forming protrusion for forming a slot. With the above improvements, the forming protrusion will be placed in the forming cavity when the mold is closed, so that the inside of the handle shell after forming is formed into a slot.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] By setting a snap-on demolding structure on the upper template, the snap-on demolding structure includes a first slider horizontally inserted on the upper template, a second slider slidably disposed on the first slider, a third slider slidably disposed on the second slider, and a drive unit for driving the first slider to slide. The second slider is vertically inserted into the molding cavity, and the third slider is horizontally placed in the molding mounting groove. After injection molding is completed, the drive unit pulls the first slider outward, causing the second slider to move upward and driving the third slider away from the molding area of ​​the slot, thereby demolding the slot and realizing demolding the slot in a limited space.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0027] like Figure 1-4 As shown, an injection mold for a concealed door handle includes an upper template 1, a lower template 2, and a molding plate 3 disposed on the upper template 1 and the lower template 2.

[0028] Specifically, the molding plates 3 form a molding cavity 4 for molding the handle housing 8, and the handle housing 8 is spaced out with an installation groove 5. The installation groove 5 forms a slot 6. The upper template 1 is provided with a snap-on demolding structure 7. The snap-on demolding structure 7 includes a first slider 1.1 horizontally inserted on the upper template 1, a second slider 1.2 slidably disposed on the first slider 1.1, a third slider 1.3 slidably disposed on the second slider 1.2, and a driving unit 1.4 for driving the first slider 1.1 to slide.

[0029] Furthermore, the second slider 1.2 is vertically inserted into the molding cavity 4, and the third slider 1.3 is horizontally placed in the mounting groove 5. The driving unit 1.4 drives the first slider 1.1 to move horizontally, so that the second slider 1.2 moves up and down, and drives the third slider 1.3 to move closer to or away from the molding area of ​​the slot 6.

[0030] During the entire injection molding process, the upper mold plate 1 and the lower mold plate 2 first close the mold. At the same time, the drive unit 1.4 drives the first slider 1.1 to slide into the upper mold plate 1 and the second slider 1.2 to slide downward. As the second slider 1.2 descends, the third slider 1.3 moves toward the molding area of ​​the slot 6 to perform injection molding. After the injection molding is completed, the drive unit 1.4 pulls the first slider 1.1 outward, causing the second slider 1.2 to move upward and the third slider 1.3 to move away from the molding area of ​​the slot 6, thereby demolding the slot 6 and achieving demolding of the slot 6 in a limited space.

[0031] like Figure 1-4 As shown, a further explanation of the cooperation between the first slider 1.1, the second slider 1.2, and the third slider 1.3 in this embodiment is provided: the first slider 1.1 has an inclined first groove 2.1, and the second slider 1.2 has a first sliding protrusion 2.2. The first sliding protrusion 2.2 is slidably disposed in the first groove 2.1. The first groove 2.1 and the first sliding protrusion 2.2 cooperate with each other. As the driving unit 1.4 pushes the first slider 1.1 to slide horizontally, it drives the second slider 1.2 to slide up and down, thereby driving the third slider 1.3 away from or closer to the forming area of ​​the slot 6.

[0032] Furthermore, a second sliding groove 2.3 is formed on the second slider 1.2, and a second sliding protrusion 2.4 is formed on the second slider 1.2. The second sliding protrusion 2.4 is slidably disposed in the second sliding groove 2.3. The second sliding groove 2.3 and the second sliding protrusion 2.4 cooperate with each other. When the second slider 1.2 slides up and down, the third slider 1.3 will move away from or closer to the forming area of ​​the slot 6 to achieve demolding.

[0033] like Figure 1-4 As shown, as a further explanation of the embodiment of the first slider 1.1, the first slider 1.1 is horizontally inserted into the upper template 1, and the first slider 1.1 is driven to move within the upper template 1 by the driving unit 1.4.

[0034] Specifically, a confirmation observation rod 2.6 is connected to the first slider 1.1. When the upper mold plate 1 and the lower mold plate 2 are in the mold closing state, the confirmation observation rod 2.6 extends out of the upper mold plate 1 to indicate that the upper mold plate 1 and the lower mold plate 2 have been closed in place, and allows the molding engineer to visually confirm whether the drive unit 1.4 is operating normally.

[0035] Furthermore, the upper template 1 forms a sliding channel 2.7 for the confirmation observation rod 2.6 to slide. The confirmation observation rod 2.6 is inserted into the sliding channel 2.7 to guide the confirmation observation rod 2.6 and improve the stability of the confirmation observation rod 2.6 during the sliding process.

[0036] In addition, a wear-resistant plate 3.1 is provided inside the upper template 1, and the wear-resistant plate 3.1 abuts against the upper surface of the first slider 1.1. The wear-resistant plate 3.1 can not only guide the first slider 1.1 and ensure its stability during the sliding process, but also reduce the frictional resistance between it and the first slider 1.1, so as to increase the service life of the slider and the mold.

[0037] Preferably, the drive unit 1.4 is a hydraulic cylinder.

[0038] like Figure 1-4 As shown, as a further explanation of the embodiment of the second slider 1.2, the second slider 1.2 is vertically connected to the first slider 1.1, and the molding plate 3 forms a demolding groove 2.5 for the second slider 1.2 to slide, which improves the stability of the second slider 1.2 during the sliding process.

[0039] Furthermore, a guide block 3.2 is provided inside the upper template 1. The guide block 3.2 has a guide groove 3.3 for the second slider 1.2 to be inserted. The guide groove 3.3 guides the second slider 1.2 to ensure the stability of the second slider 1.2 during the up and down sliding process.

[0040] like Figure 1-4As shown, as a further explanation of the embodiment of the third slider 1.3, the third slider 1.3 is horizontally connected to the second slider 1.2. The third slider 1.3 constitutes a forming protrusion 3.4 for forming the groove 6. The forming protrusion 3.4 will be placed in the forming cavity 4 when the mold is closed, so that the inside of the handle housing 8 after forming is formed into the groove 6.

[0041] In some other embodiments, the upper template 1 is provided with several snap-on demolding structures 7. Through the above improvements, multiple handle shells 8 can be formed at one time to improve molding efficiency.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
