Abstract
Description
Technical Field

[0002] The dial back cover is the main component of a watch. The dial back covers of mainstream electronic watches on the market are mostly made of plastic materials. Therefore, the dial back cover needs to be produced by plastic mold injection cooling molding to obtain a dial back cover with a certain structure.
[0003] Generally, both ends of the dial back cover need to be assembled and connected with the strap (bracelet) to realize the wearability of the electronic watch. With the development of personalized wearable design of electronic watches, the structure of electronic watches has also become more complicated. The key to assembling the dial back cover and the strap is the connection hole structure on the dial back cover (such as Figure 1 shown).
[0004] In order to meet the injection molding requirements of the connection hole structure of the dial back cover and ensure the molding quality requirements of the dial back cover, it is necessary to set a slide structure on the plastic mold to complete the core pulling action. Figure 2 (as shown in the figure), the slider performs a single linear reciprocating motion along the inclined stroke groove of the rear mold core to open and close the mold core pulling and resetting actions. Although the design of the slider structure and the processing of each component are relatively simple and convenient, in the actual mold trial and production process, due to the presence of a sharp-angled glue sealing position at the front end of the slider fixed on the slider, and the presence of a sharp-angled glue sealing position at the connection between the end of the inclined stroke groove and the rear mold core molding cavity, when the slider insert moves along the inclined stroke groove toward the rear mold core molding cavity during mold closing, it is easy for the sharp corner of the front end of the slider insert to bump or hit the sharp corner of the rear mold core molding cavity, resulting in a defective glue sealing position, so that the injection molding quality requirements of the dial back cover cannot be ensured.

[0037] See also Figures 1 to 7 In order to better understand the slide structure 10 of the plastic mold for the dial back cover of the present application, the slide structure 10 of the plastic mold for the dial back cover is further explained below:
[0038] The sliding structure 10 of the plastic mold for the dial back cover of one embodiment includes a guide reset bent pin 300, a slider assembly 400 and a core pulling molding assembly 500. One end of the guide reset bent pin 300 is detachably mounted on the fixed mold mechanism. The front end of the slider assembly 400 is located in the core pulling stroke slot 103. The core pulling molding assembly 500 includes a first core pulling insert 510 and a second core pulling insert 520; the first core pulling insert 510 is detachably connected to the front end of the slider assembly 400, and the first core pulling insert 510 and the front end of the slider assembly 400 jointly cover the second core pulling insert 520, so that the second core pulling insert 520 is slidably connected to the slider assembly 400 and the first core pulling insert 510; the front end of the first core pulling insert 510 is formed with a molding area 5110, the The molding area 5110 is provided with a punch insertion opening 5101, and a core pulling punch portion 5210 is formed at the front end of the second core pulling insert 520. The other end of the guide reset bent pin 300 extends to the rear end of the slider assembly 400, so that the core pulling punch portion 5210 is driven by the slider assembly 400 to move against the punch insertion opening 5101, and the slider assembly 400, the first core pulling insert 510 and the second core pulling insert 520 can move in the horizontal direction to pull the core or reset.
[0039] In this embodiment, the first core-pulling insert 510 is detachably connected to the front end of the slider assembly 400, and the first core-pulling insert 510 moves in the horizontal direction to pull the core, replacing the traditional slider-driven movement of the sliding position insert along the inclined travel groove. The problem of the sharp corners around the molding area 5110 at the front end of the first core-pulling insert 510 causing collisions with the rear mold core 200 can be effectively avoided, thereby effectively ensuring the integrity of the sealing position, thereby ensuring the molding quality of the dial back cover.
[0040] Furthermore, since the other end of the guide reset bent pin 300 extends to the rear end of the slider assembly 400, the core-pulling punch part 5210 can be driven by the slider assembly 400 to move against the punch penetration opening 5101; and then the slider assembly 400, the first core-pulling insert 510 and the second core-pulling insert 520 can complete the mold opening, core pulling and mold closing and reset in the horizontal direction, thereby effectively meeting the injection molding of the connecting hole structure and increasing the rationality of the slide structure design to meet the injection molding quality requirements of the dial back cover.
[0041] like Figures 3 to 6As shown, in one embodiment, the first core-pulling insert 510 is provided with a first core-pulling air-avoiding groove 5102 communicating with the punch hole 5101, and the second core-pulling insert 520 is partially disposed in the first core-pulling air-avoiding groove 5102. In one embodiment, the slider assembly 400 includes a bottom slider base 410, the front end of the bottom slider base 410 is located at the core-pulling stroke notch 103, and is slidably connected to the inner wall of the second notch 102; the front end of the bottom slider base 410 is provided with a second core-pulling air-avoiding groove 4101, the first core-pulling air-avoiding groove 5102 and the second core-pulling air-avoiding groove 4101 together form a core-pulling air-avoiding cavity 401, and the second core-pulling insert 520 is located in the core-pulling air-avoiding cavity 401. In one of the embodiments, a sliding channel 4102 connected to the second core-pulling avoidance groove 4101 is formed at the rear end of the bottom slider base 410; the slider assembly 400 also includes an intermediate slider base 420, and an oblique guide groove 4201 is formed at the front end of the intermediate slider base 420, and a guide protrusion 5220 is formed at the rear end of the second core-pulling insert 520, and the guide protrusion 5220 is slidably connected to the oblique guide groove 4201; the rear end of the intermediate slider base 420 is located in the sliding channel 4102 and is slidably connected to the inner wall of the sliding channel 4102.
[0042] It can be understood that in this embodiment, the outer walls of the second core pulling insert 520 and the intermediate slider base 420 are both processed with multiple wear-resistant oil grooves. By applying lubricating oil to the outer walls of the second core pulling insert 520 and the intermediate slider base 420, the lubricating oil is filled into the wear-resistant oil grooves, thereby enabling the second core pulling insert 520 and the inner wall of the core pulling cavity 401 to be slidably connected more smoothly. Specifically, when the front mold core 100 and the rear mold core 200 are opened, the other end of the guide reset bent pin 300 first drives the middle slider base 420 to slide relative to the sliding channel 4102 in the direction away from the rear mold core 200, so that the guide slide protrusion 5220 slides obliquely relative to the oblique guide slide groove 4201, so that the core pulling punch portion 5210 at the front end of the second core pulling insert 520 withdraws from the punch penetration opening 5101 to complete the first core pulling action; when the first core pulling action is completed, the other end of the guide reset bent pin 300 drives the bottom slider base 410, the middle slider base 420, the first core pulling insert 510 and the second core pulling insert 520 to withdraw from the core pulling avoidance cavity 401 in the horizontal direction to complete the final core pulling action. The sliding structure makes the core-pulling punch part 5210 pull the core obliquely first, and then makes the first core-pulling insert 510 move in the horizontal direction to pull the core; conversely, when the mold is closed and reset, the first core-pulling insert 510 is first moved in the horizontal direction to reset, so as to avoid the problem that the sharp corners around the molding area 5110 at the front end of the first core-pulling insert 510 cause collision with the rear mold core 200, and finally the core-pulling punch part 5210 moves to abut against the punch hole 5101.
[0043] Specifically, in the present embodiment, the oblique guide groove 4201 is designed as a dovetail groove; in other embodiments, the oblique guide groove 4201 may be designed as a T-slot.
[0044] like Figure 5 and Figure 6 As shown, in one embodiment, the rear end of the bottom slider base 410 is provided with a first oblique guide hole 4103, the first oblique guide hole 4103 is connected to the sliding channel 4102, the rear end of the intermediate slider base 420 is provided with a second oblique guide hole 4202, and the other end of the guide reset bent pin 300 is movably inserted in the first oblique guide hole 4103 and the second oblique guide hole 4202 in sequence. In one embodiment, the sliding direction of the intermediate slider base 420 relative to the sliding channel 4102 is the clearance aperture of the first oblique guide hole 4103 and the second oblique guide hole 4202, and the clearance aperture of the first oblique guide hole 4103 is larger than the clearance aperture of the second oblique guide hole 4202.
[0045] It can be understood that in this embodiment, since the air avoidance diameter of the first oblique guide through hole 4103 is larger than the air avoidance diameter of the second oblique guide through hole 4202, when the mold is opened, the other end of the guide reset bent pin 300 first abuts against the inner wall of the second oblique guide through hole 4202, causing the middle slider base 420 to slide relative to the sliding channel 4102, thereby driving the core pulling punch portion 5210 at the front end of the second core pulling insert 520 to withdraw from the punch penetration opening 5101, effectively avoiding the influence of the core pulling punch portion 5210 on demolding.
[0046] When the mold is closed, the other end of the guide reset bent pin 300 first abuts against the inner wall of the second inclined guide through hole 4202, so that the middle slider base 420 slides relative to the sliding channel 4102, thereby driving the core pulling punch part 5210 at the front end of the second core pulling insert 520 to abut against the punch hole 5101; secondly, the other end of the guide reset bent pin 300 abuts against the inner wall of the first inclined guide through hole 4103, so that the bottom slider base 410 drives the middle slider base 420, the first core pulling insert 510 and the second core pulling insert 520 to reset along the horizontal movement, effectively solving the problem of the sharp corners around the molding area 5110 at the front end of the first core pulling insert 510 causing collision with the rear mold core 200.
[0047] like Figure 5 and Figure 6 As shown, in one embodiment, a hanging platform protrusion 310 is formed at one end of the guide reset bent pin 300, and the hanging platform protrusion 310 is arranged in the mounting hole of the fixed mold mechanism (not shown in the figure), and the hanging platform protrusion 310 is square. In one embodiment, the sliding structure 10 of the plastic mold for the dial back cover also includes a fixed limit assembly 600, and the fixed limit assembly 600 includes a first fixed plate 610, and the first fixed plate 610 is covered at the opening of the mounting hole (not shown in the figure) and is screwed to the fixed mold mechanism; the first fixed plate 610 is provided with a first air avoidance gap 6101 connected to the mounting hole (not shown in the figure), and the hanging platform protrusion 310 is partially located in the first air avoidance gap 6101.
[0048] It can be understood that in this embodiment, the guide reset bent pin 300 can be an integrally formed structure, so that the guide reset bent pin 300 can have a high structural strength, and the first fixed plate 610 is used to fix and limit the hanging platform convex part 310 of the guide reset bent pin 300, so that the other end of the guide reset bent pin 300 can reliably drive the middle slider base 420 and the bottom slider base 410 to complete the mold opening core pulling and mold closing reset. At the same time, the first fixed plate 610 cover is screwed with the fixed mold mechanism, which is also convenient for the removal and installation of the hanging platform convex part 310 of the guide reset bent pin 300.
[0049] like Figures 5 to 7As shown, in one embodiment, the fixed limit assembly 600 further includes a second fixed plate 620, the second fixed plate 620 is covered in the sliding channel 4102 and is screwed to the bottom slider base 410, and the second fixed plate 620 is provided with a second air-avoiding notch 6201 aligned with the first air-avoiding notch 6101. In one embodiment, the slide structure 10 of the plastic mold for the dial back cover further includes a wear-resistant assembly 700, the wear-resistant assembly 700 includes a first wear-resistant squeeze block 710 and a second wear-resistant squeeze block 720 respectively located on the two side walls of the bottom slider base 410, and the bottom slider base 410 is slidably connected to the first wear-resistant squeeze block 710 and the second wear-resistant squeeze block 720.
[0050] It can be understood that in order to ensure the stability of the sliding of the middle slider base 420 relative to the sliding channel 4102, the second fixing plate 620 is covered on the sliding channel 4102 to reduce other degrees of freedom of the middle slider base 420. At the same time, in order to ensure the smoothness of the bottom slider base 410 to withdraw from the core-pulling cavity 401, it is necessary to respectively set the first wear-resistant squeeze block 710 and the second wear-resistant squeeze block 720 on the two side walls of the bottom slider base 410; and in this embodiment, the area where the first wear-resistant squeeze block 710 and the second wear-resistant squeeze block 720 are slidably connected to the bottom slider base 410 is also opened and processed with a plurality of wear-resistant oil grooves, which further improves the smoothness of the sliding connection of the bottom slider base 410.
[0051] Compared with the prior art, the utility model has at least the following advantages:
[0052] 1. The first core-pulling insert is detachably connected to the front end of the slider assembly, and the first core-pulling insert moves in the horizontal direction to pull the core, replacing the traditional slider driving the slide insert to move along the inclined stroke groove. The problem of the sharp corners around the molding area at the front end of the first core-pulling insert causing collisions with the rear mold core can be effectively avoided, thereby effectively ensuring the integrity of the sealing position, thereby ensuring the molding quality of the dial back cover.
[0053] 2. Since the other end of the guide reset bent pin extends to the rear end of the slider assembly, the core-pulling punch part can be driven by the slider assembly to move against the punch penetration opening; then the slider assembly, the first core-pulling insert and the second core-pulling insert can complete the mold opening, core pulling and mold closing and reset in the horizontal direction, thereby effectively meeting the injection molding of the connecting hole structure and increasing the rationality of the slide structure design to meet the injection molding quality requirements of the dial back cover.
[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
