Recently, good news came from the National Intellectual Property Administration: Ningbo Zhongtuo Mold Technology Co., Ltd. has obtained a utility model patent titled “An Injection Mold for Automotive Front Compartment Trim Parts,” with the authorization announcement number CN 223442723 U and the application date of November 2024.

According to the patent abstract, this patent belongs to the field of mold structure technology and aims to provide a more efficient injection mold for automotive front compartment trim parts. The mold features multiple innovations in structural design: by incorporating an auxiliary mechanism and a pneumatic press on the fixed mold, and by designing appropriate cavities and channels, the mold utilizes gas action for demolding of the formed parts. This eliminates the time required for suction cup gripping in traditional processes, thereby effectively improving the production efficiency of the injection mold.

Specifically, the patented technical solution includes core components such as a fixed mold, a movable mold, and hydraulic cylinders. The movable mold has a second cavity on the end face facing the fixed mold, while the fixed mold has a first cavity on the end face facing the movable mold. The movable mold is equipped with a clearance cavity on the inner wall of the first cavity. Combined with the auxiliary mechanism’s synchronization frame, insertion rod, and retaining ring structures, this design enables more precise and efficient mold opening, closing, and demolding operations.

Ningbo Zhongtuo Mold Technology Co., Ltd. currently holds 32 patent records, demonstrating the company’s sustained investment and considerable strength in technological innovation. As automotive front compartment trim parts are an important component of both interior and exterior automotive finishes, the mold technology directly affects product quality and production efficiency. The acquisition of this patent will further enhance Zhongtuo Mold’s technical competitiveness in the field of automotive interior trim molds and provide strong support for expanding into the high-end customer market.
