Description
Technical Field
The invention relates to an automobile roof mould, in particular to a material forming prepressing mechanism for the automobile roof mould.
Background
At present, the yield of a plurality of automobile roof products is low, wherein one key factor influencing the yield is the base material and the fabric wrinkles of the roof products; and the roof is an automobile interior appearance part, and the requirement on the appearance of the roof by a host factory is higher, so that the design change times of roof molds are more, the rejection rate of products is high, and the development cost and the development period of the products are increased.
Disclosure of Invention
The invention aims to provide a material forming pre-pressing mechanism for an automobile roof mould, which aims to solve the problem that the automobile roof mould in the prior art has high reject ratio during material forming.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a material shaping prepressing mechanism for car roof mould, its includes the shaping and goes up the mould, the shaping is gone up the mould and is included material effective area and material invalid area, wherein, go up on the shaping in be provided with at least one set of first prepressing mechanism in the material effective area, first prepressing mechanism includes that first profile inserts, go up on the shaping in be provided with at least one set of second prepressing mechanism in the material invalid area, second prepressing mechanism includes that the second profile inserts, be provided with die-cut edge of a knife on the second profile inserts, first profile inserts and the second profile inserts all and be connected with the drive arrangement who drives its up-and-down motion.
In particular, the first profile insert and the second profile insert are each connected to a drive which is independent of one another.
In particular, a heat shield is arranged between the drive and the first and second profile inserts.
In particular, the first and second profile inserts are each connected to a respective drive device by a connecting rod.
In particular, the driving means employs either a cylinder or an oil cylinder.
Particularly, the end of the connecting rod is provided with a threaded section, threaded holes are formed in the first profile insert and the second profile insert correspondingly, and the threaded section is screwed in the threaded holes and fixed through nuts.
Compared with the prior art, the material forming prepressing mechanism for the automobile roof mold has the advantages that the first profile insert is driven by the driving device, so that materials can flow into the mold body more fully, the second profile insert breaks in an invalid area before the materials are formed through the punching blade, the ductility of the materials is improved, the step of manually cutting the fabric is omitted, the production labor cost is reduced, the risk of wrinkling of the products can be reduced, the risk of tension cracking of the products is reduced, and the yield is improved.
