The auxiliary instrument panel is made of injection molding material and is injection molded by a plastic mold. Since the side of the auxiliary instrument panel needs to be embedded in the car body, a deeper side structure is required as a connection position. When the existing auxiliary instrument panel injection mold is demolded after injection molding, due to the deep sides of the plastic part, when the ejector rod is used to eject the mold, the demolding space between the two sides of the plastic part and the template is small, which is prone to jamming and the ejection is not smooth. Therefore, it is urgently needed to design an automobile auxiliary instrument panel body injection mold with an inverted slider demolding mechanism that can overcome the above defects.
