Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts manufacturing technology, specifically to an improved gate for automotive interior parts molds. Background Technology

[0002] Automotive interior parts mainly refer to automotive products used for interior modifications, covering all aspects of the car's interior. Among these, the sunroof frame is a key automotive interior part, primarily made of plastic. In actual production, to ensure dimensional accuracy, injection molds are generally used. However, existing injection molds for automotive interior parts typically use a circular gate, resulting in higher injection pressure and consequently, greater product deformation. Therefore, to address these issues, an improved gate design for automotive interior parts molds is proposed to better meet practical application requirements. Utility Model Content

[0003] The purpose of this invention is to provide an improved gate for automotive interior parts molds to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved gate mold for automotive interior parts, comprising a base plate, a lower mold, and an upper mold. The lower mold is fixed on the base plate and mates with the upper mold. A pouring gate is installed on the upper mold, and a runner is installed inside the upper mold. A connecting port is fixed at the upper end of the runner, and the connecting port is connected to the pouring gate. Guide tubes are evenly distributed at the lower end of the runner, and the guide tubes are connected to the injection nozzle. The injection nozzle is connected to the fan-shaped inlet.

[0005] Preferably, a guide post is fixed on the lower mold, and the guide post and the upper mold are slidably connected. The sliding guiding effect between the guide post and the upper mold can ensure the accurate assembly of the lower mold and the upper mold.

[0006] Preferably, the lower mold has a mold groove, and the mold groove is connected to the fan-shaped injection port. The above structure can ensure the normal operation of product injection molding production.

[0007] Preferably, a vertical rod is fixed between the lower mold and the base plate, and the vertical rod is slidably connected to the movable plate. When the movable plate moves, the sliding guide effect between the vertical rod and the movable plate can ensure the stability of the movable plate's movement.

[0008] Preferably, ejector pins are also evenly fixed on the movable plate, and the ejector pins are slidably connected to the lower mold. Through the action of the ejector pins, the product can be ejected after production, which facilitates the unloading of the product.

[0009] Preferably, a cylinder is also fixed on the movable plate, and the output end of the cylinder is fixed on the base plate. Through the action of the cylinder, a basic force can be provided for the movement of the movable plate to ensure the normal operation of the device.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the improved gate automotive interior part mold adopts a distributed point injection structure, which can effectively disperse the injection pressure and improve the injection quality, and make the material distribution more uniform and rapid, thereby improving the injection efficiency. Combined with the fan-shaped gate structure, it can achieve a flat injection effect, thereby further dispersing the injection pressure and avoiding product deformation during the injection process.

[0016] 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.

[0017] Please see Figure 1-Figure 4This utility model provides a technical solution: an improved gate mold for automotive interior parts, including a base plate 1, a lower mold 2 and an upper mold 6. The lower mold 2 is fixed on the base plate 1 and cooperates with the upper mold 6. A pouring gate 7 is installed on the upper mold 6. A runner 8 is installed inside the upper mold 6. A connection port 801 is fixed at the upper end of the runner 8 and is connected to the pouring gate 7. Guide pipes 802 are evenly distributed at the lower end of the runner 8 and are connected to the injection nozzle 803. The injection nozzle 803 is connected to the fan-shaped inlet 804.

[0018] A guide post 201 is fixed on the lower mold 2, and the guide post 201 is slidably connected to the upper mold 6; a model groove 202 is opened in the lower mold 2, and the model groove 202 is connected to the fan-shaped injection port 804; a vertical rod 3 is also fixed between the lower mold 2 and the base plate 1, and the vertical rod 3 is slidably connected to the movable plate 4; ejector pins 401 are also evenly fixed on the movable plate 4, and the ejector pins 401 are slidably connected to the lower mold 2; a cylinder 5 is also fixed on the movable plate 4, and the output end of the cylinder 5 is fixed on the base plate 1;

[0019] When using this improved gate automotive interior parts mold, such as Figure 1-Figure 4 As shown, the upper mold 6 and lower mold 2 are first assembled. The sliding guide between the guide post 201 and the upper mold 6 ensures accurate assembly of the upper mold 6 and lower mold 2. After assembly, injection molding can be performed through the sprue 7. The material enters the runner 8 through the sprue 7 and the connecting port 801 for distribution. Combined with the function of the guide tube 802, the material can be injected through multiple injection nozzles 803. Furthermore, the fan-shaped inlet 804 enables flat injection, thereby dispersing the injection pressure and effectively preventing defects. The product deforms, allowing the rubber material to be evenly injected into the mold groove 202. After injection molding, the upper mold 6 separates from the lower mold 2. By controlling the extension of the cylinder 5, the movable plate 4 can be moved upward. With the sliding guide effect between the vertical rod 3 and the movable plate 4, the stability of the movement of the movable plate 4 can be ensured. When the movable plate 4 moves, it also drives the ejector pin 401 to move upward, so that the ejector pin 401 can eject the molded product in the mold groove 202, which is convenient for unloading. This is the working principle of the improved gate automotive interior part mold.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
