[0002] Hot-stamped grilles are an important component of commercial vehicles, as the hot-stamping process increases their durability and visual inspection capabilities.

[0003] Currently, hot stamping grilles for commercial vehicles are generally made of plastic and are manufactured using injection molds. Due to the design of multiple holes in the grille, when using traditional injection molds to inject hot stamping grilles, the molten plastic needs to gradually fill the grille nodes and then flow into the next grille node. This injection method affects the processing efficiency of hot stamping grilles. Therefore, we designed an injection mold for hot stamping grilles for commercial vehicles to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to provide injection molds for hot stamping grilles for commercial vehicles, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: an injection mold for hot stamping grilles of commercial vehicles, including a lower fixed plate and an upper fixed plate. Two supporting upright plates are fixedly installed on both sides of the top of the lower fixed plate. A lower mold base is fixedly installed on the top of the two supporting upright plates. A sprue plate is fixedly installed at the bottom of the upper fixed plate. An upper mold base is fixedly installed at the bottom of the sprue plate. A lower mold core is detachably fixedly installed on the top of the lower mold base. A grille piece that is integrally connected is fixedly installed on the surface of the lower mold core. A uniformly distributed protrusion is fixedly installed on the surface of the grille piece. A recess is opened between two adjacent protrusions.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-5 As shown, the injection mold for hot stamping grille of commercial vehicle of this utility model includes a lower fixed plate 1 and an upper fixed plate 3. Two supporting upright plates 2 are fixedly installed on both sides of the top of the lower fixed plate 1. A lower mold base 4 is fixedly installed on the top of the two supporting upright plates 2. A sprue plate 6 is fixedly installed at the bottom of the upper fixed plate 3. An upper mold base 5 is fixedly installed at the bottom of the sprue plate 6. A lower mold core 9 is detachably fixedly installed on the top of the lower mold base 4. A grille piece 10 that is connected as one piece is fixedly installed on the surface of the lower mold core 9. A uniformly distributed protrusion 16 is fixedly installed on the surface of the grille piece 10. A recess 17 is opened between two adjacent protrusions 16. An adhesive flow channel 18 is provided between the protrusions 16 and the recess 17.

[0020] Specifically, during the injection molding process, the hot stamping grid injection mold utilizes the protrusions 16 and recesses 17 on the surface of the grid sheet 10 to cooperate, and provides an adhesive flow channel 18 between the protrusions 16 and the recesses 17. This ensures that the adhesive flows quickly into the recesses 17, replacing the traditional method of filling each recess 17 one by one before flowing into the next recess 17, thus improving the processing efficiency of the hot stamping grid.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the injection mold for the hot stamping grille of the commercial vehicle of this utility model has multiple slots 11 equidistantly opened on the surface of the lower mold core 9, and the slots 11 are nested and connected with inserts 12 of appropriate size.

[0022] A movable movable plate 7 is placed in the middle of the lower fixed plate 1. Multiple inclined push rods 8 are hinged to the top of the movable plate 7. The tops of the multiple inclined push rods 8 pass through the lower mold base 4 and are fixedly connected to the bottom of the insert 12.

[0023] Specifically, through the cooperation of multiple inclined ejector rods 8 and inserts 12, multiple inserts 12 can move upward synchronously during demolding, ensuring stable demolding of the hot stamping grid and avoiding the problem of local damage to the hot stamping grid due to concentrated force during demolding.

[0024] Multiple mounting slots 14 are equidistantly provided on the side of the lower mold core 9, and the mounting slots 14 are fixedly connected to the lower mold base 4 by bolts.

[0025] Specifically, the lower mold core 9 and the lower mold base 4 are detachably fixed together by bolts, which facilitates the replacement of the lower mold core 9 when it is damaged.

[0026] Multiple cooling pipe connection holes 15 are equidistantly provided on both sides of the lower mold base 4 and the upper mold base 5, and guide post assembly holes 13 are provided at the four corners of the top of the lower mold base 4.

[0027] Specifically, by assembling the limiting guide post through the guide post assembly hole 13, the mold closing accuracy between the lower mold base 4 and the upper mold base 5 can be improved.

[0028] The bottom of the upper mold base 5 is fixedly installed with an upper mold core. The surface of the upper mold core is provided with multiple grooves that match the protrusions 16. The middle part of the upper mold base 5 is provided with a glue inlet hole.

[0029] Specifically, multiple grooves cooperate with the protrusions 16 to form multiple grid holes in the hot stamping grid.

[0030] In specific implementation, when using the hot stamping grid injection mold, the hot stamping grid injection mold is first fixedly installed in the injection molding machine body. When the lower mold base 4 and the upper mold base 5 are closed, the protrusion 16 of the grid plate 10 is inserted into the groove opened in the middle of the upper mold base 5, so that a grid cavity is formed between the upper mold base 5 and the lower mold base 4. At this time, the glue flows into the grid cavity from the glue nozzle. Through the glue flow channel 18 opened between the protrusion 16 and the recess 17, it can be ensured that the glue flows steadily into the recess 17, avoiding the grid from being unable to form connecting ribs due to the blockage of the protrusion 16, thus ensuring the integrity of the hot stamping grid molding. At the same time, the glue flow channel 18 can accelerate the filling of the mold cavity with glue and improve the processing efficiency. After the injection is completed, the electric cylinder of the injection molding machine pushes the movable plate 7, and the multiple inclined ejector rods 8 at the top of the movable plate 7 push the multiple inserts 12 to move upward, ensuring the stable demolding of the hot stamping grid.
