Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to an injection mold for a license plate light bracket. Background Technology

[0002] In industrial production, the importance of molds is self-evident, especially for the production of plastic products. Molds are even more crucial, as most plastic products used in people's production and daily life rely on molds. License plate light brackets, for example, also require molds for production.

[0003] Reference Figure 1 and Figure 2 The license plate light bracket body 01 has an arc-shaped groove 011 on one side and a mounting groove 012 and a mounting hole 013 on the other side. The mounting hole 013 is connected to the arc-shaped groove 011. A buckle 014 is fixedly connected to the lower end of the license plate light bracket body 01 near the arc-shaped groove 011. To meet the injection molding requirements of the license plate light bracket body 01, it is not possible to directly achieve demolding of the license plate light bracket by separating the upper and lower molds. Utility Model Content

[0004] In order to meet the injection molding requirements of the license plate light bracket body and facilitate the demolding of the license plate light bracket body, this application provides a license plate light bracket injection mold.

[0005] The technical solution for the license plate light bracket injection mold provided in this application is as follows:

[0006] A license plate light bracket injection mold includes an upper mold base, a lower mold base, and a demolding assembly. The lower mold base is slidably connected to the upper mold base, and the sliding direction of the lower mold base is vertical. The upper mold base has a molding cavity on one side along the sliding direction of the lower mold base. A molding boss is connected to one side of the lower mold base along the sliding direction of the lower mold base. The molding boss corresponds to the molding cavity in position and is adapted in shape. The demolding assembly is slidably connected to the lower mold base, and the demolding assembly corresponds to the molding boss in position.

[0007] By adopting the above technical solution, the demolding component, together with the molding cavity and molding boss, is used to mold the license plate light bracket, which meets the injection molding requirements of the license plate light bracket body. After the upper mold base and the lower mold base are separated, the demolding component slides, so that the limiting of the demolding component on the license plate light bracket disappears, realizing the demolding of the license plate light bracket and making it easy to remove the license plate light bracket.

[0008] Preferably, the demolding assembly includes a first molding slider, which is slidably connected to one side of the lower mold base. The sliding direction of the first molding slider is perpendicular to the sliding direction of the lower mold base. A first molding block is connected to the side of the first molding slider near the molding boss. The first molding block is used to be embedded in the mounting groove and mounting hole of the license plate light bracket body. A guide rod is connected to the surface of the upper mold base near the lower mold base. The end of the guide rod away from the upper mold base is inclined away from the molding cavity. The first molding slider is provided with a guide groove. The axis of the guide groove coincides with the axis of the guide rod. The guide groove is used for the guide rod to slide into the mold base.

[0009] By adopting the above technical solution, when the upper mold base and the lower mold base separate, the guide rod abuts against the guide groove wall, driving the first forming slider to slide away from the forming protrusion, thereby realizing the separation of the first forming slider and the license plate light bracket.

[0010] Preferably, the demolding assembly further includes a third forming slider and a first push block. The third forming slider is slidably connected to the lower mold base, and the sliding direction of the third forming slider is parallel to the sliding direction of the lower mold base. The end of the third forming slider near the upper mold base is connected to a third forming block. The third forming block is used to be embedded in the buckle of the license plate light bracket body. The third forming slider is provided with a first abutting groove. One end of the first push block is connected to the first forming slider, and the other end of the first push block is slidably embedded in the first abutting groove. The end of the first push block away from the first forming slider is inclined away from the upper mold base.

[0011] By adopting the above technical solution, the first forming slider slides, which drives the first push block to slide. The first push block abuts against the first abutting groove, which drives the third forming slider to slide away from the upper mold base, thereby realizing the separation of the third forming slider and the license plate light bracket.

[0012] Preferably, the demolding assembly further includes a second forming slider and a driving component. The second forming slider is slidably connected to the lower mold base, and the sliding direction of the second forming slider is parallel to the sliding direction of the first forming slider. The second forming slider is used to be embedded in the arc-shaped groove of the license plate light bracket body. The driving component is connected to the lower mold base and is used to drive the second forming slider to slide.

[0013] By adopting the above technical solution, the driving component works, causing the second forming slider to slide away from the forming protrusion, thereby realizing the separation of the second forming slider and the license plate light bracket.

[0014] Preferably, it further includes an ejection assembly, which includes an ejection base plate and ejector pins. The lower mold base has a plurality of ejection slots evenly distributed thereon. The ejection base plate is slidably connected to the side of the lower mold base away from the forming boss. The sliding direction of the ejection base plate is parallel to the sliding direction of the lower mold base. The number of ejector pins is the same as the number of ejection slots and corresponds one-to-one. One end of the ejector pin is connected to the ejection base plate, and the other end of the ejector pin is slidably embedded in the ejection slot. The sliding direction of the ejector pin is parallel to the sliding direction of the ejection base plate. The ejector pin is used to push the license plate light bracket body to slide.

[0015] By adopting the above technical solution, the ejector plate slides, which drives the ejector pins to slide, thereby pushing the license plate light bracket away from the forming boss, realizing the separation of the license plate light bracket and the forming boss. Multiple ejector pins are set to reduce stress concentration at the contact point between the ejector pins and the license plate light bracket, reduce the possibility of damage to the license plate light bracket, and improve production efficiency.

[0016] Preferably, the ejection assembly further includes an ejector rod, the lower mold base is provided with a fifth connecting groove, one end of the ejector rod is connected to the ejection base plate, the other end of the ejector rod is slidably embedded in the fifth connecting groove, and the end of the ejector rod away from the ejection base plate is flush with the side surface of the lower mold base near the upper mold base.

[0017] By adopting the above technical solution, when the upper mold base and the lower mold base are not separated, the upper end of the ejector pin abuts against the upper mold base to achieve relative fixation of the ejector base plate and the lower mold base, reducing the possibility of the ejector pin colliding with the cavity wall of the forming cavity, causing damage to the ejector pin and the upper mold base, and improving the service life of the mold.

[0018] Preferably, it also includes a protection component, which includes a contact switch and an abutment block. The contact switch is connected to the lower mold base, and the abutment block is connected to the ejection base plate. The abutment block is used to abut the contact switch, and the contact switch is used to send a signal to an external driving source.

[0019] By adopting the above technical solution, the ejector base plate slides away from the upper mold base, causing the ejector pin to slide and embed into the ejector groove. This causes the contact block to abut against the contact switch, which sends a signal to the external drive source to indicate that the ejector pin has been embedded in the ejector groove. This reduces the possibility of damage to the ejector pin and the upper mold base caused by the molding cavity wall abutting against the ejector pin when the upper mold base slides close to the lower mold base if the ejector pin is not embedded in the ejector groove, thus improving the service life of the mold.

[0020] Preferably, the upper mold base has a plurality of guide holes on the side near the lower mold base, and the plurality of guide holes are distributed at intervals along the circumference of the upper mold base. The lower mold base is connected to a plurality of guide pillars on the side near the upper mold base, and the number of guide pillars is the same as the number of guide holes and corresponds one-to-one.

[0021] By adopting the above technical solution, guide pillars and guide holes are set to guide the closing of the upper and lower mold bases, thereby improving the accuracy of the sliding of the upper and lower mold bases.

[0022] Preferably, the system further includes sleeves, the number of which is the same as the number of guide holes and corresponds one-to-one. The sleeves are coaxially embedded in the guide holes and are coaxially slidably sleeved on the outer periphery of the guide post.

[0023] By adopting the above technical solution, a sleeve is set, which is embedded in the guide hole and slidably sleeved on the outer periphery of the guide post, reducing the possibility of collision between the guide post and the upper mold base, reducing the wear of the upper mold base, and improving the service life of the mold.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The demolding component, together with the molding cavity and molding boss, is used to mold the license plate light bracket to meet the injection molding requirements of the license plate light bracket body. After the upper mold base and the lower mold base are separated, the demolding component slides, so that the limiting of the demolding component on the license plate light bracket disappears, realizing the demolding of the license plate light bracket and making it easy to remove the license plate light bracket.

[0026] 2. When the upper mold base and the lower mold base are separated, the guide rod abuts against the guide groove wall, causing the first forming slider to slide away from the forming boss. The sliding of the first forming slider causes the first push block to slide, which in turn causes the third forming slider to slide away from the upper mold base. The driving component works, causing the second forming slider to slide away from the forming boss, thereby realizing the separation of the demolding component and the license plate light bracket.

[0027] 3. The ejector plate slides, causing the ejector pins to slide, which pushes the license plate light bracket away from the forming boss, thus separating the license plate light bracket from the forming boss. Multiple ejector pins are used to reduce stress concentration at the contact point between the ejector pins and the license plate light bracket, reducing the possibility of damage to the license plate light bracket and improving production efficiency. When the upper mold base and the lower mold base are not separated, the upper end of the ejector rod abuts against the upper mold base to achieve relative fixation of the ejector plate and the lower mold base, reducing the possibility of the ejector pins colliding with the cavity wall of the forming cavity, which could lead to damage to the ejector pins and the upper mold base, and improving the service life of the mold.

[0059] The implementation principle of a license plate light bracket injection mold in this application embodiment is as follows: the ejector base plate 41 slides close to the lower fixed plate 21, causing the ejector panel 42 to slide, causing the ejector pin 43 to slide into the ejector groove 2210, the driving component 35 works, pushing the second forming slider 34 to slide close to the forming boss 221, the lower mold base 22 slides close to the upper mold base 12, the guide post 23 slides into the sleeve 15, the boss 222 is embedded in the groove 125, the forming boss 221 is embedded in the forming cavity 121, the guide rod 16 abuts against the groove wall of the guide groove 313, the first forming slider 31 slides close to the forming boss 221, causing the first connecting part 322 to slide close to the third sliding groove 226, causing the first sliding part 321 to slide, causing the first guide part 323 to slide, the first guide part 323 abuts against the first abutting groove 332, pushing the third forming block 331 to slide close to the upper mold base 12.

[0060] Raw material is injected from the positioning ring 13 and passes through the sprue sleeve 14 between the molding cavity 121 and the molding boss 221. After the license plate light bracket body cools and forms, the lower mold base 22 slides away from the upper mold base 12, and the guide rod 16 abuts against the guide groove 313, causing the first molding slider 31 to slide away from the molding boss 221 and the third molding slider 33 to slide away from the upper mold base 12. After the upper mold base 12 and the lower mold base 22 separate, the drive component 35 operates, causing the second molding slider 34 to slide away from the molding boss 221. The ejector plate 41 slides closer to the lower mold base 22, causing the ejector panel 42 to slide, causing the ejector rod 44 to slide out of the ejector groove 2210, pushing the license plate light bracket body away from the molding boss 221, making it easier to remove the license plate light bracket body.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
