Description

Injection mold for large-size thin sheet Technical Field The utility model relates to the technical field of injection molds, in particular to an injection mold for large-size sheets. Background The sheet injection mold is a tool for producing sheet plastic products, which processes plastic materials into sheet products with specific shapes and sizes by means of injection molding technology, and different types of sheet injection molds play a key role in the processing of materials such as rubber, plastic and the like and the production of products. In the prior art, because the injection molding machine has the requirement of minimum die thickness, products with large size and thin wall thickness are produced, because the projection area is large, the large-tonnage injection molding machine is required to be used, in order to meet the requirement of minimum die thickness of the injection molding machine, the thin-wall products are often thick, and the weight and the cost of the die are increased. Disclosure of utility model The utility model aims at solving the problems that in the prior art, because an injection molding machine has the requirement of minimum die thickness, products with large sizes and thin wall thickness have large projection areas, and because the injection molding machine with large tonnage is required to be used, in order to meet the requirement of minimum die thickness of the injection molding machine, thin-wall products are often too thick, and the weight and cost of the die are increased. In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model relates to a large-size sheet injection mold which comprises a lower fixing plate and an upper fixing plate, wherein a supporting plate is fixedly arranged on the upper surface of the lower fixing plate, an upper fixing plate is fixedly arranged at one end of the supporting plate, a B plate is fixedly arranged on the upper surface of the supporting plate, an A plate is fixedly arranged on the upper surface of the B plate, the A plate is connected with the lower surface of the upper fixing plate, a glue opening device is arranged in the upper fixing plate, the glue opening device extends between the A plate and the B plate, a cost reducing mechanism is fixedly arranged on the upper surface of the lower fixing plate, and the supporting end of the cost reducing mechanism is connected with the lower surface of the B plate. Further, the cost reducing mechanism comprises ejector plate supporting rods, and a plurality of groups of ejector plate supporting rods are fixedly arranged on the upper surface of the lower fixing plate. Further, one end of the ejector plate supporting rod is provided with an ejector plate. Further, the upper surface of the ejector plate is fixedly provided with a plurality of groups of ejector pins. Further, the upper surface mounting of thimble board has a plurality of groups to return the needle, the one end that returns the needle is all connected with the inside of B board, the surface that returns the needle has cup jointed the spring, the upper surface fixed mounting of lower fixed plate has a plurality of groups support column, and the support column of complaining is all connected with the lower surface of B board through ancient fruit thimble board.
