Problems solved by technology

[0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. It has excellent low temperature resistance, good chemical stability and electrical insulation, and is widely used in film products and plates, especially In the automobile processing industry, thermal molding is often used to prepare sound insulation and cushioning parts using polyethylene foam materials. During the preparation process, steam is required to semi-melt the polyethylene materials for molding processing, which not only has low processing efficiency, but also consumes A large amount of energy, high preparation cost, cannot meet the production requirements of energy saving and efficiency improvement

Abstract

The invention provides a double-layer die pressing machine and a die pressing system and belongs to the technical field of die pressing devices. The double-layer die pressing machine comprises a lowerdie frame, a middle die frame and an upper die frame which are sequentially arranged from bottom to top. The middle die frame and the upper die frame are arranged to be liftable. A first female die is arranged in the lower die frame. A first male die is arranged in the upper die frame. A second male die and a second female die corresponding to the first female die and the first male die are arranged in the middle die frame. The middle die frame is further connected with a steam pipe. The double-layer die pressing machine can improve the hot pressing machining efficiency of polyethylene, and steam consumption needed by machining is reduced. The invention further provides the die pressing system comprising the double-layer die pressing machine.

Description

technical field [0001] The present invention relates to the technical field of molding devices, in particular, to a double-layer molding machine and molding system. Background technique [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. It has excellent low temperature resistance, good chemical stability and electrical insulation, and is widely used in film products and sheets, especially In the automotive processing industry, the hot molding method is often used to prepare sound insulation and cushioning parts with polyethylene foam materials. During the preparation process, it is necessary to use steam to semi-melt the polyethylene material to facilitate the molding process, which not only has low processing efficiency, but also consumes The large amount of energy and the high preparation cost cannot meet the production requirements of energy saving and efficiency improvement. [0003] Therefore, there is a need for a device that c...
