Description

Technical Field

[0001] This application relates to the field of injection mold technology, and in particular to a high-gloss, seamless injection mold for passenger car air intake grilles that prevents weld lines. Background Technology

[0002] The air intake grille is a key component of the front of a car, combining functionality and design aesthetics. The production process of the air intake grille generally requires the use of injection molds to inject molten plastic into the cavity under high temperature and pressure, and the grille is formed after cooling.

[0003] However, after the grating is produced, it needs to be removed from the injection mold. Existing injection molds generally do not have auxiliary tools to facilitate the removal of the grating. If it is not removed properly, the weld lines on the grating will become clear, affecting the appearance of the product. Utility Model Content

[0004] This application provides a high-gloss, seamless injection mold for passenger vehicle air intake grilles that prevents weld lines, in order to solve the problems of injection molds.

[0005] This application provides a high-gloss, seamless injection mold for passenger vehicle air intake grilles that prevents weld lines. The mold includes a fixed mold, a moving mold, a cavity, a filling hole, a positioning hole, and a positioning rod. Both sides of the cavity have material-removing grooves, and a material-removing slider is slidably connected to the inner wall of each groove. The side wall of the material-removing slider has an extension groove, which communicates with the cavity. The extension groove contains a pushing device. First, the material-removing slider slides into the material-removing groove, then the connection between the fixed mold and the moving mold is completed, and finally, the molten plastic is injected. The molten plastic is injected into the mold cavity through the injection hole. The molten plastic then fills the mold cavity and the extended sprue connected to the mold cavity. When it is necessary to remove the mold, the fixed mold and the moving mold are separated first. Then, the material removal sliders in the material removal grooves on both sides of the mold cavity can be pulled. The two sets of material removal sliders are connected to the grid in the mold cavity through the solidified injection molten plastic in the material removal grooves, so they can be removed together. This makes it easier for the staff to remove the material, reduces the chance of material breakage during removal, avoids accidental injury, and reduces the generation of weld lines.

[0006] Preferably, the pushing device includes a pushing slider slidably connected to the inner wall of the extended material groove, and a pushing rod fixedly connected to the side wall of the pushing slider. The other end of the pushing rod passes through the extended material groove and extends to the outside of the picking slider, and the pushing rod is slidably connected to the picking slider. A connecting push block is fixedly connected to one end of the pushing rod located outside the picking slider. After the grid is removed from the cavity, the picking slider needs to be separated from the grid. At this time, the connecting push block can be fixed. When the picking slider is pulled, the picking slider will slide along the pushing rod, and the pushing slider will fix the connecting material in the extended material groove. Then the picking slider moves outward to expose the connecting material in the extended material groove, which facilitates the separation of the picking slider from the grid. The pushing rod will push out the residual material in the extended material groove for easy use next time.

[0007] Preferably, there are three sets of pusher slides, and the three sets of pusher slides are located at the upper, middle and lower parts of the pusher slide, respectively. The design of three sets of pusher slides is beneficial to improving the stability of the material picking slide when it moves.

[0008] Preferably, multiple sets of reinforcing grooves are provided on both sides of the material taking slider, and the material taking groove on one side of the reinforcing groove is fixedly connected to the side wall of the moving mold with a reinforcing slider. By setting the reinforcing groove and the reinforcing slider, after the fixed mold and the moving mold are connected, the two sets of reinforcing sliders will slide into the reinforcing groove, thereby fixing the material taking slider in the material taking groove, completing the fixing work of the material taking slider, so that the material taking slider in the material taking groove will not move randomly during the melting and plasticizing process, which facilitates the melting and plasticizing work.

[0009] Preferably, the material picking slider, the material pushing slider, the material pushing rod, and the connecting push block are all made of high-temperature resistant material. The design of high-temperature resistant material improves the durability of the above-mentioned device and extends its service life.

[0010] Preferably, a heat-insulating soft rubber pad is fixedly connected to the side wall of the connecting push block. By setting the heat-insulating soft rubber pad, the skin is prevented from being burned by the high temperature of the connecting push block during the melting process, and the operating comfort is improved.

[0011] Preferably, the side wall of the fixed mold has multiple sets of positioning holes, and the side wall of the moving mold located on one side of the positioning holes is fixedly connected with a positioning rod. By setting the positioning holes and positioning rod, after the fixed mold and the moving mold have completed the connection work, the reinforcing slider of the fixed mold and the moving mold will be on one side of the reinforcing groove, which makes it convenient for the reinforcing slider to slide into the reinforcing groove and complete the fixing work. Beneficial effects

[0012] Considering the issues with injection molds, when it is necessary to remove the mold, the fixed mold and the moving mold are first separated. Then, the material removal sliders in the material removal grooves on both sides of the cavity can be pulled. The two sets of material removal sliders are connected to the grid in the cavity through the solidified injection molten material in the material removal grooves, so they can be removed together. This facilitates the material removal work of the staff, reduces the chance of material breakage during removal, avoids accidental injury, and reduces the generation of weld lines.

[0027] This utility model provides, for example Figure 1-4 The image shows a high-gloss, seamless injection mold for a passenger vehicle's air intake grille, designed to prevent weld lines.

[0028] This application provides a high-gloss, seamless injection mold for passenger vehicle air intake grille that prevents weld lines, including a fixed mold 1, a moving mold 2, a cavity 3, a filling hole 4, a positioning hole 14, and a positioning rod 15. Both sides of the cavity 3 are provided with material picking grooves 5, and the inner wall of the material picking groove 5 is slidably connected to a material picking slider 6. The side wall of the material picking slider 6 is provided with an extension groove 7, and the extension groove 7 is connected to the cavity 3. The interior of the extension groove 7 is provided with a pushing device.

[0029] First, the material-retrieving slider 6 is slid into the material-retrieving groove 5. Then, the connection between the fixed mold 1 and the moving mold 2 is completed. Next, the molten plastic is injected into the cavity 3 through the injection hole 4. At this time, the molten plastic will fill the cavity 3 and the extended material groove 7 connected to the cavity 3. When it is necessary to remove the mold, the fixed mold 1 and the moving mold 2 are separated first. Then, the material-retrieving slider 6 in the material-retrieving groove 5 on both sides of the cavity 3 can be pulled. The two sets of material-retrieving sliders 6 are connected to the grid in the cavity 3 through the solidified injection molten plastic in the material-retrieving groove 5, and can be removed together. This facilitates the material-retrieving work of the staff, reduces the chance of material breakage during material retrieval, avoids accidental injury, and reduces the generation of weld lines.

[0030] The pushing device includes a pushing slider 8 that is slidably connected to the inner wall of the extended material groove 7, and a pushing rod 9 is fixedly connected to the side wall of the pushing slider 8. The other end of the pushing rod 9 passes through the extended material groove 7 and extends to the outside of the picking slider 6. The pushing rod 9 is slidably connected to the picking slider 6. A connecting push block 10 is fixedly connected to one end of the pushing rod 9 located outside the picking slider 6.

[0031] After removing the grid from cavity 3, the material taking slider 6 needs to be separated from the grid. At this time, the push block 10 can be fixedly connected. When the material taking slider 6 is pulled, the material taking slider 6 will slide along the push slide rod 9, while the push slide 8 will fix the connecting material in the extension groove 7. Then the material taking slider 6 moves outward to expose the connecting material in the extension groove 7, which facilitates the separation of the material taking slider 6 from the grid. The push slide 8 will push out the residual material in the extension groove 7 for easy use next time.

[0032] There are three sets of pusher slides 9, and the three sets of pusher slides 9 are located at the upper, middle and lower parts of the pusher slider 8, respectively.

[0033] The design of three sets of pusher slides 9 helps to improve the stability of the material take-up slider 6 when it moves.

[0034] Multiple sets of reinforcing grooves 11 are provided on both sides of the material picking slider 6, and the material picking groove 5 located on one side of the reinforcing groove 11 and the side wall of the moving mold 2 are fixedly connected to the reinforcing slider 12.

[0035] By setting up a reinforcing groove 11 and a reinforcing slider 12, after the fixed mold 1 and the moving mold 2 are connected, the two sets of reinforcing sliders 12 will slide into the reinforcing groove 11, thereby fixing the material take-up slider 6 in the material take-up groove 5, completing the fixing work of the material take-up slider 6, so that the material take-up slider 6 in the material take-up groove 5 will not move randomly during the melting process, which facilitates the melting process.

[0040] The side wall of the fixed mold 1 has multiple sets of positioning holes 14, and the side wall of the moving mold 2 located on one side of the positioning holes 14 is fixedly connected with a positioning rod 15.

[0041] By setting positioning holes 14 and positioning rods 15, after the fixed mold 1 and the moving mold 2 are connected, the positioning rods 15 will slide into the positioning holes 14. At this time, the reinforcing sliders 12 of the fixed mold 1 and the moving mold 2 will be on one side of the reinforcing groove 11, which makes it convenient for the reinforcing sliders 12 to slide into the reinforcing groove 11 and complete the fixing work.

[0042] Working Principle: When using this high-gloss, seamless injection mold for passenger vehicle grilles that prevents weld lines, the material take-up slider 6 is first slid into the material take-up groove 5. Then, the connection between the fixed mold 1 and the moving mold 2 is completed. Next, the molten plastic is poured into the cavity 3 through the filling hole 4. At this time, the molten plastic fills the cavity 3 and the extended material groove 7 connected to the cavity 3. When it is necessary to remove the mold, the fixed mold 1 and the moving mold 2 are first separated. Then, the material take-up sliders 6 in the material take-up grooves 5 on both sides of the cavity 3 can be pulled. The two sets of material take-up sliders 6 pass through the solidified injection molten plastic in the material take-up grooves 5. It is connected to the grid in cavity 3 so that it can be removed together. After removing the grid from cavity 3, the material taking slider 6 needs to be separated from the grid. At this time, the push block 10 can be fixedly connected. When the material taking slider 6 is pulled, the material taking slider 6 will slide along the push slide 9. The push slide 8 will fix the connecting material in the extension groove 7. Then the material taking slider 6 moves outward to expose the connecting material in the extension groove 7, which facilitates the separation of the material taking slider 6 from the grid. The push slide 9 will push out the residual material in the extension groove 7 for easy use next time.
