Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a molding die for an automotive armrest box cover. Background Technology

[0002] Currently, the processing of car armrest box covers involves workers performing milling and partial wire cutting on a piece-by-piece basis according to production drawings, resulting in a complex production process. Due to the complex structure and long processing cycle of car armrest box covers, this method is not suitable for mass production.

[0003] The mold for forming the top cover of the car armrest box includes an upper mold base and a lower mold base. By injecting coolant into the upper and lower mold bases, the mold can be quickly separated from the forming groove after the hot casting process is completed. An electric push rod is provided between the upper and lower mold bases so that the mold can be pushed out.

[0004] A search of CN219988331U reveals a molding die for a new energy vehicle armrest box cover, relating to the field of automotive armrest box cover molding technology. The die includes an upper mold base and a lower mold base. A molding groove is formed on the top of the lower mold base, and a base is provided on the top of the molding groove. An electric push rod is connected to the center of the top of the base. A first liquid inlet hole is formed on the side of the upper mold base, and a second liquid inlet hole is formed on the side of the lower mold base. This invention achieves rapid separation of the mold from the molding groove after hot casting by injecting coolant into the upper and lower mold bases. The electric push rod between the upper and lower mold bases allows for easy removal of the mold. The rectangular venting groove ensures timely discharge of gases generated during the molding process, improving production efficiency, reducing labor intensity, and achieving high-efficiency, low-energy production.

[0005] However, when the electric push rod pushes the forming mold, there is a situation where the forming mold sticks to the forming cavity. Directly pushing with brute force can easily cause the forming mold to wear and twist at the edges or scratch the mold cavity due to adhesion, which affects the production efficiency of the armrest box cover.

[0006] Therefore, it is necessary to provide a mold for forming the top cover of an automotive armrest box to solve the above-mentioned technical problems. Utility Model Content
