Description

Technical Field

[0001] This utility model relates to the technical field of injection molding, and in particular to a raw material addition device for automotive injection molding. Background Technology

[0002] Some automotive parts made of rubber or plastic are manufactured using injection molding. During injection molding, the rubber or plastic raw material granules are first heated and melted using a heating device, then fed into the injection port and poured into the mold to cool and solidify.

[0003] Existing injection molding equipment typically connects the injection port to a dedicated hopper. When a different material needs to be injection molded, it is inconvenient to change the material or requires cleaning the entire hopper, which is quite cumbersome. Utility Model Content

[0004] This invention aims to address the shortcomings of existing technologies by providing a raw material addition device for automotive injection molding.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A raw material adding device for automotive injection molding includes an n-shaped frame. A docking discharge pipe is rotatably mounted on the middle of the horizontal plate of the n-shaped frame via a bearing. The docking discharge pipe includes an upper docking vertical pipe, a middle connecting bend, and a lower rotating vertical pipe. The rotating vertical pipe is rotatably mounted inside the bearing. A docking flange is provided at the top of the docking vertical pipe. A double hopper device is provided above the n-shaped frame. The double hopper device includes two hoppers, which are symmetrically arranged about the center line of the bearing. A discharge port is provided at the bottom of the hopper, and an end face flange is provided at the bottom of the discharge port. A stirring device and a heating device are provided inside the hopper, and a feed port is provided at the top of the hopper. The docking flange of the docking discharge pipe is tightly fitted and docked with the end face flange of one of the hoppers.

[0007] A limiting plate is provided on the side wall of the vertical pipe, and limiting posts are symmetrically provided on the horizontal plate of the n-shaped frame. A limiting pin is provided between the limiting plate and one of the limiting posts.

[0008] An overlapping platform is provided at the upper end of the inner wall of the connecting vertical pipe, and a U-shaped filter screen is placed on the overlapping platform.

[0009] The mixing device includes a mixing shaft installed inside the hopper, a mixing motor connected to the mixing shaft, and several mixing blades on the mixing shaft.

[0010] The heating device is a heating rod installed at the lower end of the side wall of the hopper, which extends into the hopper.

[0011] The beneficial effects of this utility model are: this utility model can conveniently rotate the connecting feed tube to two hoppers, which facilitates injection molding of two materials. It eliminates the need to clean and replace the entire hopper; only the connecting feed tube needs to be cleaned, making it more efficient and faster. Attached Figure Description
