Description

Technical Field

[0001] This application relates to the technical field of injection molds, and in particular to a four-sided slider mold structure. Background Technology

[0002] In the consumer electronics field, the mid-frame of various types of displays serves as both a supporting structure and the overall appearance, making its design and manufacturing precision crucial. Existing mid-frames generally employ a unibody design with continuous, curved sidewalls. During injection molding, this type of structure typically utilizes four sliding blocks within the mold, which together form the 360° sidewall molding surfaces of the mid-frame.

[0003] However, the split-type four-sided slider structure commonly used in the industry has structural weaknesses during hoisting and use. Due to its own weight, the left and right sliders will settle towards the center of the earth. This slight displacement directly damages the original assembly precision of the mold. Taking a slider with a single-sided design clearance of 0.05mm as an example: after hoisting and settling, the actual clearance on the top side will increase to approximately 0.1mm, causing high-pressure melt to overflow during mold closing, forming burrs and severely reducing the first-pass yield and production efficiency. Meanwhile, the clearance on the bottom side will decrease to zero, or even become interference fit, leading to abnormally increased friction on the sliding surface. This not only causes wear but, in extreme cases, can cause mold jamming, threatening production safety. Utility Model Content

[0033] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0034] Please see Figures 1 to 5This invention relates to a four-sided slider mold structure 10, comprising a mold blank 100, a mold core 200, a four-sided slider assembly 300, and multiple wear-resistant components 400. The mold core 200 is embedded in the mold blank 100, and together with the mold core, forms four sliding grooves 101. The four-sided slider assembly 300 includes four sliders 310, each disposed within a corresponding sliding groove 101. The four sliders 310 and the mold core 200 together form a cavity 201. The four sliders 310 are respectively a top-side slider 311, a bottom-side slider 312, a left-side slider 313, and a right-side slider 314. The two ends of the left-side slider 313 have a first fitting clearance with the top-side slider 311 and the bottom-side slider 312, respectively. The two ends of the right-side slider 314 have a second fitting clearance with the top-side slider 311 and the bottom-side slider 312, respectively. The fitting clearance ranges from 0.01mm to 0.03mm. Each wear-resistant component 400 includes two side wear-resistant strips 410, a wear-resistant block 420, and a first wear-resistant guide strip 430. The two side wear-resistant strips 410 are respectively disposed on both sides of the inner wall of the corresponding slide groove 101 and are slidably connected to the slider 310. The wear-resistant block 420 is disposed at the bottom of the slider 310. The first wear-resistant guide strip 430 is disposed in the middle of the inner wall of the corresponding slide groove 101. A guide groove 3101 is opened at the bottom of the slider 310 corresponding to the first wear-resistant guide strip 430. The first wear-resistant guide strip 430 is slidably connected to the guide groove 3101 so that the slider 310 slides along the slide groove 101.

[0035] It should be noted that in this embodiment, each wear-resistant strip 410 is a side mold steel wear-resistant strip, the wear-resistant block 420 is a mold steel wear-resistant block, the first wear-resistant guide strip 430 is a first mold steel wear-resistant guide strip, and the hardness of each wear-resistant strip 410, wear-resistant block 420 and first wear-resistant guide strip 430 is HRC58-62.

[0036] In this embodiment, the four-sided slider mold structure 10 uses four sliders 310 to jointly form the cavity 201, enabling the product to be formed in one step and adapting to the forming of complex structures such as continuous appearance surfaces with arc transitions on all four side walls. The four-sided slider mold structure 10 reduces the mating gap between the left and right sliders 310 and the top and bottom sides, thus suppressing the increase in the mating gap on the top side of the left and right sliders 310 due to gravity, thereby avoiding the formation of flash and improving the first-pass yield and production efficiency. The four-sided slider mold structure 10 improves the wear resistance of the groove 101 and sliders 310 by setting wear-resistant components 400, extending the service life of the mold. Specifically, a first wear-resistant guide strip 430 is provided in the middle of the groove 101 to guide the movement of the sliders 310. Furthermore, the first wear-resistant guide strips 430 on the left and right sides are connected to the sliders 310 to form a constraint, suppressing the decrease in the mating gap on the bottom side of the left and right sliders 310 due to gravity, thereby avoiding mold jamming and improving production reliability and safety.

[0037] like Figure 1 As shown, in one embodiment, both the top-side slider 311 and the bottom-side slider 312 are provided with rounded corner forming portions 3111, which are used to form the four rounded corners of the product. It can be understood that the four rounded corners of the product are formed by the rounded corner forming portions 3111 of the top-side slider 311 and the bottom-side slider 312 respectively. A single slider 310 completely forms a continuous curved surface, avoiding discontinuities and flash on the arc surface, thus improving product quality. At the same time, the structure of the top and bottom-side sliders 310 is simple, avoiding interference within the mold and improving overall reliability.

[0038] like Figures 2 to 5 As shown, in one embodiment, the bottom of the slider 310 has a first mounting groove 3102, and the wear-resistant block 420 is disposed in the first mounting groove 3102. The wear-resistant block 420 has a first through hole (not shown). The first mounting groove 3102 has a first connecting hole 3103 corresponding to the first through hole. The four-sided slider mold structure 10 also includes a first connector 500, which passes through the first through hole and connects to the first connecting hole 3103, so that the wear-resistant block 420 and the slider 310 are detachably connected. The first connector 500 enables quick disassembly of the wear-resistant block 420, allowing the wear-resistant block 420 to be replaced individually without replacing the entire slider 310, thus extending the service life of the slider 310. Specifically, in this embodiment, there are four connectors, four first through holes, and four first connecting holes 3103. The four through holes are located at the four corners of the wear-resistant block 420. By utilizing the connection points distributed at the four corners, a uniform and stable clamping force is provided to the wear-resistant block 420 to prevent the wear-resistant block 420 from loosening or shifting during use and to ensure the stability of the wear-resistant block 420.

[0039] Furthermore, such as Figures 2 to 5 As shown, in one embodiment, two wear-resistant blocks 420 are symmetrically arranged at the bottom of the slider 310 to prevent the slider 310 from getting stuck or tilting due to wear on one side or uneven force, thereby improving the stability of the slider 310 and ensuring product quality.

[0040] like Figures 2 to 5As shown, in one embodiment, a fourth mounting groove 1013 is provided at the bottom of the slide 101. A first wear-resistant guide strip 430 is disposed in the fourth mounting groove 1013. The first wear-resistant guide strip 430 has a fifth through hole (not shown). A fifth connecting hole 1014 is provided in the fourth mounting groove 1013 corresponding to the fifth through hole. The four-sided slider mold structure 10 also includes a fifth connecting member (not shown). The fifth connecting member passes through the fifth through hole and connects to the fifth connecting hole 1014, so that the first wear-resistant guide strip 430 is detachably connected to the mold core 200. By fixing the first wear-resistant guide strip 430 in the fourth mounting groove 1013 through the fifth connecting member, the stability and structural strength of the connection between the first wear-resistant guide strip 430 and the mold core 200 are further improved, thereby suppressing the change in the mating clearance between the top and bottom sides of the left and right sliders 310 due to gravity, thereby improving product quality and production efficiency. At the same time, the first wear-resistant guide strip 430 can be individually disassembled and replaced through the fifth connecting member, extending its service life and improving maintenance efficiency.

[0041] like Figures 2 to 5 As shown, in one embodiment, the wear-resistant component 400 further includes two second wear-resistant guide strips 440, which are respectively located on both sides of the slider 310. The slider 310 is slidably connected to the corresponding side wear-resistant strips 410 via the second wear-resistant guide strips 440, so that the slider 310 slides along the groove 101. It can be understood that the connection position between the slider 310 and the side wear-resistant strips 410 is a location where stress and wear are concentrated. By setting the second wear-resistant guide strips 440, the wear resistance on both sides of the slider 310 is improved, and the overall service life of the slider 310 is extended.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the slider 310 has receiving grooves 3104 on both sides, and the second wear-resistant guide strip 440 is disposed in the corresponding receiving groove 3104. The second wear-resistant guide strip 440 has a second through hole (not shown). The bottom of the receiving groove 3104 has a second connecting hole 3107 corresponding to the second through hole. The four-sided slider mold structure 10 also includes a second connector (not shown). The second connector passes through the second through hole and connects to the second connecting hole 3107, so that the second wear-resistant strip and the slider 310 can be detachably connected. It can be understood that by fixing the second wear-resistant guide strip 440 in the receiving groove 3104 through the second connector, displacement of the second wear-resistant guide strip 440 is prevented during use, improving the stability of the slider 310's movement, realizing the quick disassembly and installation of the second wear-resistant guide strip 440, and improving maintenance efficiency. Meanwhile, by cooperating with the second wear-resistant guide strip 440 and the side wear-resistant strip 410, the stability of the fit gap between the sliders 310 is further improved, and the fit gap between the top and bottom sides of the left and right sliders 310 is suppressed due to gravity, thereby improving product quality and production efficiency.

[0043] It should be noted that in this embodiment, each of the second wear-resistant guide strips 440 is a second mold steel wear-resistant guide strip, and the hardness of each of the second wear-resistant guide strips 440 is HRC58-62.

[0044] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the wear-resistant component 400 further includes a mold core wear-resistant block 450, which is disposed at the bottom of the slide groove 101 and is disposed opposite to the wear-resistant block 420.

[0045] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the bottom of the slide 101 has a second mounting groove 1011 corresponding to the wear-resistant block 420. The mold core wear-resistant block 450 is located in the corresponding second mounting groove 1011. The mold core wear-resistant block 450 has a third through hole (not shown). The mold core 200 has a third connecting hole 1012 corresponding to the third through hole. The four-sided slider mold structure 10 also includes a third connecting member (not shown). The third connecting member passes through the third through hole and connects to the third connecting hole 1012, so that the mold core wear-resistant block 450 and the mold core 200 are detachably connected. The mold core wear-resistant block 450 can be replaced separately without repairing or replacing the mold core 200, thus improving maintenance efficiency. Specifically, the mold core wear-resistant block 450 is set to correspond to the wear-resistant block 420 on the slider 310, further improving wear resistance and thus extending the overall service life.

[0046] It should be noted that in this embodiment, the wear-resistant block 450 is a mold steel wear-resistant block, and the hardness of the wear-resistant block 450 is HRC58-62.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the wear-resistant component 400 further includes a guide groove wear-resistant block 460. A third mounting groove 3105 is provided at the bottom of the slider 310, communicating with the guide groove 3101. The guide groove wear-resistant block 460 is disposed within the third mounting groove 3105 and is detachably connected to the slider 310. It is understood that the guide groove wear-resistant block 460 enhances the wear resistance of the guide groove 3101 and allows for individual replacement and maintenance, improving maintenance efficiency and extending service life. Furthermore, the cooperation between the first wear-resistant guide strip 430 and the wear-resistant guide groove further improves the stability of the mating clearance, suppressing changes in the mating clearance on the top and bottom sides of the left and right sliders 310 due to gravity, thereby improving product quality and production efficiency.

[0048] Furthermore, a fourth through hole (not shown) is provided on both sides of the guide groove wear-resistant block 460, and a fourth connecting hole 3108 is provided on both sides of the guide groove 3101. The four-sided slider mold structure 10 also includes a fourth connecting member 600, which passes through the fourth through hole and connects to the fourth connecting hole 3108. The symmetrical connection on both sides by the fourth connecting member 600 ensures that the guide groove wear-resistant block 460 is subjected to uniform force, improving the reliability of the connection between the slider 310 and the guide groove wear-resistant block 460, as well as the rigidity and stability of the structure.

[0049] It should be noted that, in this embodiment, the guide groove wear-resistant block 460 is a mold steel guide groove wear-resistant block, and the hardness of the guide groove wear-resistant block 460 is HRC58-62.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the four-sided slider 310 mold structure 10 further includes multiple elastic elements 700. The slider 310 has a receiving hole 3106 on its side facing the cavity 201. Each elastic element 700 is located within a corresponding receiving hole 3106, and both ends of the elastic element 700 abut against the inner wall of the mold core 200 and the inner wall of the receiving hole 3106, respectively. Specifically, in this embodiment, the slider 310 has two symmetrically arranged receiving holes 3106 on its side facing the cavity 201. During mold closing, the elastic elements 700 in the receiving holes 3106 are compressed between the inner wall of the mold core 200 and the bottom of the receiving holes 3106, storing elastic potential energy. During core pulling, the slider 310 slides along the slide groove 101 in a direction away from the cavity 201, and the elastic elements 700 release energy, accelerating the slider 310's sliding reset and improving production efficiency. Meanwhile, two symmetrically arranged receiving holes 3106 and elastic elements 700 are used to avoid tilting or jamming caused by uneven force, ensuring the smooth movement of the slider 310, thereby ensuring the closing accuracy of the cavity 201 and effectively preventing quality problems such as flash and dimensional deviation caused by the slider 310 not being reset properly.

[0051] Compared with the prior art, this application has at least the following advantages:

[0052] 1. The above-mentioned four-sided slider mold structure uses four sliders to form a molding cavity, which enables the product to be formed in one step and is suitable for forming complex structures such as continuous appearance surfaces with arc transitions on all four sides.

[0053] 2. The four-sided slider mold structure reduces the mating clearance between the left and right sliders and the top and bottom sides, thereby suppressing the increase in the mating clearance of the left and right sliders on the top side due to gravity, thus avoiding the formation of flash and improving the first pass rate and production efficiency.

[0054] 3. The four-sided slider mold structure enhances the wear resistance of the slide groove 101 and the slider by incorporating wear-resistant components, thus extending the mold's service life. Specifically, a wear-resistant guide strip is installed in the middle of the slide groove to guide the slider's movement. Furthermore, the wear-resistant guide strips on the left and right sides connect to the slider, forming a constraint to suppress the reduction of the mating clearance between the left and right slider sides due to gravity, thereby preventing mold jamming and improving production reliability and safety.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
