The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, in the embodiment, the lifting type forming mechanism of the automobile roof mold comprises a mold body 1, first forming assemblies 2 for forming four corner columns of the automobile roof are arranged at four corners of the mold body 1, a group of second forming assemblies 3 for forming side columns of the automobile roof are symmetrically arranged on side edges of the mold body 1, the first forming assemblies 2 and the second forming assemblies 3 both adopt a lifting type structure, the first forming assemblies 2 comprise first movable inserts 4 which move up and down along a vertical direction, the first movable inserts 4 are connected with first driving cylinders 5, the second forming assemblies 3 comprise second movable inserts 6 which move along a normal direction of any molding surface of the roof and a mold opening direction, the second movable inserts 6 are arranged on movable insert guide blocks 8 through guide rails 7, the guide rails 7 are arranged in a direction matched with the normal direction of the molding surface of the roof, the movable insert guide block 8 is connected with the second driving cylinder 9, the guide rail 7 is assembled on the die body 1 through a guide rail fixing block 10, and the first movable insert 4 and the second movable insert 6 are internally provided with an electric heating tube 11 for heating the corresponding movable inserts and a thermocouple 12 for monitoring the temperature of the corresponding movable inserts.
