Description

Technical Field

[0001] The utility model relates to the field of rubber injection molding machines, in particular to a rubber injection molding machine provided with a split-mode rapid blanking and forming die. Background Art

[0002] A rubber injection molding machine is a piece of equipment for the production of rubber molded products. It is mainly used for the production of rubber molded products, such as electrical insulation parts, shock pads, seals, shoe soles, and industrial and mining rain boots. A rubber injection molding machine generally includes an injection device, a mold opening and closing device, a heating and cooling device, a hydraulic transmission system, and an electrical control system.

[0003] Currently, an existing rubber injection molding machine has a feeding structure and a flipping structure. Due to a large number of existing production batches, the mold structure has also become large. There is a phenomenon of redundant edge material in the feeding mold of the existing rubber injection molding machine, resulting in waste of raw materials. And the flipping structure has problems such as inconvenient operation, large operation load, and inconvenient movement during mold change. If there is only one, it will further reduce the production efficiency.

[0004] Most of the existing rubber injection molding machines cannot adjust the rapid demolding of small batch parts according to different application scenarios and product requirements. When used to manufacture rubber products with small sizes or large sizes, they cannot well adapt to the sizes of different manufactured products and rapidly demold and blank, directly affecting the quality and performance of the products.

[0005] At the same time, the forming and demolding die of a general rubber injection machine is relatively simple; it is not matched with the connection of other actuating parts. This not only makes the transmission insensitive, but also the whole machine cannot be used when a failure occurs in the whole machine device. Summary of the Utility Model
