[0002] Automobile hinges are important parts that connect car doors and car bodies, and are used to realize the opening and closing functions of car doors. The heating and forming of automobile hinges is often completed using a hot press. Materials suitable for hot press plate forming are selected, usually metal materials such as steel or stainless steel, and then the materials are cut into sheets of appropriate sizes for subsequent hot press plate forming operations. Then, hot press plate equipment is prepared, including a hot press and a hot press plate. After the hot press plate is preheated to a suitable temperature, the cut hinge parts are placed on the hot press plate, and then the hot press plate is placed in the preheated hot press. By applying appropriate pressure and temperature, the hinge parts are plastically deformed under the action of the hot press plate to achieve the desired shape and size. However, when using a hot press, it is often necessary to replace the heat transfer oil in the hot press oil and clean the pipeline. The existing method of sealing the oil storage pipe is to inject a lead block at the opening. Although this method can better withstand huge pressure and seal the heat transfer oil, it is more cumbersome when removing and installing the lead block, and it is more likely to cause damage to the heating plate due to improper operation.

[0003] In view of the above problems, a heating device for automobile hinge molding is proposed. Utility Model Content
