[0002] The car grille is the mesh or slatted component in the center of the front of a car, usually surrounding the car logo and covering the front of the radiator (water tank). It is an important part of the front design and function of a car.

[0003] For example, patent application number 202421588761.9 published on the China Patent Network, entitled "A Multi-Cavity Injection Mold for Automotive Grilles," includes an upper top plate, an upper template, a lower template, a vertical plate, an ejector plate, and a lower bottom plate. The upper template has a core cavity in its center, and a movable core block that slides up and down along the cavity is located within the core cavity. A spring abuts against the upper end of the movable core block, and the upper end of the spring abuts against the upper top plate. An injection needle is embedded in the upper top plate. The movable core block has a central hole through which the injection needle passes. Several upper transverse flow channels connecting various molding cavities are formed on the lower end face of the movable core block. These upper transverse flow channels are connected to the lower end of the injection needle. A cutting core block is embedded in the cutting groove, and a first ejector rod is connected to the lower end of the cutting core block. The lower end of the first ejector rod passes through the lower template and abuts against the ejector plate. This design achieves separation of the sprue and product within the mold, leaving no burrs on the product surface. It eliminates the need for additional cutting processes, improving product quality while accelerating production efficiency.

[0004] However, existing injection molds installed inside injection molding machines directly tilt and discharge the molded car grilles during the material discharge process. The falling car grilles are prone to damage due to falling, resulting in a lower processing qualification rate.

[0005] Therefore, it is necessary to redesign and modify the molding equipment used for automotive grilles. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, the present invention provides a molding equipment for automotive grilles, including an injection molding machine 1;

[0028] The injection molding machine 1 has an injection mold 2 installed at the injection end. The surface of the injection molding machine 1 has a groove 3. A lifting plate 4 is installed inside the groove 3. A receiving plate 5 is installed on the top of the lifting plate 4. The receiving plate 5 is located at the bottom of the injection mold 2. A transmission structure 6 is installed on the surface of the injection mold 2. The transmission structure 6 can control the vertical lifting of the lifting plate 4 when the injection mold 2 is opened and closed.

[0029] refer to Figure 3 The transmission structure 6 includes a transmission plate 7 fixedly connected to both sides of the moving mold surface of the injection mold 2. An inclined groove 8 is provided on the surface of the transmission plate 7. An extension plate 9 is fixedly connected to the surface of the lifting plate 4. Both ends of the extension plate 9 extend to the outside of the transmission plate 7 and are fixedly connected to a force rod 10 located inside the inclined groove 8. The force rod 10 is slidably connected to the inclined groove 8.

[0030] As a technical optimization of this utility model, the horizontal motion of mold opening is converted into the vertical motion of lifting plate 4 by the inclined groove 8 of transmission plate 7 through the inclined surface driving force rod 10, which can greatly improve the structural transmission stability and save the operation steps of setting up additional drive equipment.

[0031] refer to Figure 3 Guide rods 11 are fixedly connected to the four corners of the lifting plate 4. The bottom end of the guide rods 11 extends into the interior of the injection molding machine 1 and is slidably connected to the injection molding machine 1.

[0032] As a technical optimization of this utility model, by setting the guide rod 11, the lifting plate 4 can be limited, so as to avoid the lifting plate 4 tilting during the movement.

[0033] refer to Figure 3 A connecting block 12 is fixedly connected to the top of the lifting plate 4. The receiving plate 5 is movably connected to the connecting block 12 through a pin. The receiving plate 5 can tilt and swing about the pin on the surface of the connecting block 12 as the axis.

[0034] As a technical optimization of this utility model, by setting the connecting block 12, the lifting plate 4 and the receiving plate 5 can be movably connected, which makes it easier for the receiving plate 5 to tilt and discharge the workpiece.

[0035] refer to Figure 3 An upright plate 13 is fixedly connected to the back of the injection molding machine 1. Both sides of the bottom of the receiving plate 5 are fixedly connected to a shift fork 14. The side of the shift fork 14 away from the receiving plate 5 extends to the outside of the upright plate 13. A limiting rod 15 located inside the shift fork 14 is fixedly connected to the surface of the upright plate 13. The shift fork 14 is slidably connected to the limiting rod 15. The shift fork 14 is set in a bent and hollow shape.

[0036] As a technical optimization of this utility model, by setting up the upright plate 13, the shift fork 14 and the limiting rod 15, the tilt angle of the receiving plate 5 can be controlled during the lifting process of the lifting plate 4, and the vertical displacement of the lifting plate 4 can be converted into the tilt angle change of the receiving plate 5.

[0037] refer to Figure 4 A storage frame 16 is fixedly connected to the top of the receiving plate 5. The storage frame 16 is located at the bottom of the injection mold 2 and can receive the car grille discharged from the injection mold 2. The storage frame 16 is elastic.

[0038] As a technical optimization of this utility model, by setting up the storage frame 16, the workpiece can be protected, further reducing the collision damage between the workpiece and the receiving plate 5.

[0039] The working principle and usage process of this utility model are as follows: During the operation of the injection molding machine 1, molten plastic is injected into the mold cavity to form a car grille. When a material discharge operation is required, the injection mold 2 separates, and the moving mold of the injection mold 2 carries the transmission plate 7 to move to the right. The inclined groove 8 on the transmission plate 7 acts on the force rod 10. Due to the inclined surface design of the inclined groove 8, the force rod 10 slides in the groove, converting the horizontal movement of the moving mold into a vertical lifting force. Driven by the force rod 10, the lifting plate 4 moves vertically upward along the guide rod 11. The receiving plate 5 rises with the lifting plate 4 to a position directly below the bottom of the injection mold 2, ready to receive the material. After the mold is fully opened, the formed car grille is discharged from the mold cavity. Since the receiving plate 5 has risen to its position, the grille falls directly into the storage frame 16 on top of the receiving plate 5, avoiding a long free fall. After the receiving plate 5 completes receiving, the injection mold 2 resets and reverses the above steps. The lifting plate 4 carries the receiving plate 5 down, while the vertical plate 13 on the back of the injection molding machine 1 is fixed with a limit rod 15. When the lifting plate 4 moves down, the shift fork 14 slides relative to the limit rod 15. Due to the bent and hollowed-out design of the shift fork 14, the limit rod 15 restricts its movement path, forcing the receiving plate 5 to tilt and swing around the pin of the connecting block 12. The tilting action causes the car grille in the storage frame 16 to slide down the inclined surface, thereby achieving the effect of convenient and safe discharge of the grille workpiece.

[0040] In summary, this automotive grille molding equipment, by setting up a lifting plate 4 and a receiving plate 5 that are linked to the injection mold 2, automatically and precisely raises the receiving plate 5 to below the bottom of the mold when the mold opens, so that the molded grille falls directly into the receiving plate 5 instead of falling freely, which can achieve the effect of buffering and protecting the grille workpiece.
