It adopts unique injection molding technology and foaming process, and can quickly produce lightweight and highly elastic products in a short time. The product structure of EVA injection foaming machine is mainly composed of barrel, injection device, mold, foaming agent system and other parts. A door frame structure is provided on the front side of the mold, and the door frame structure includes a door frame, a sealing plate and a glass plate. The sealing plate is connected to the door frame, and the glass plate can be connected to the door frame in an up-and-down manner. The sealing plate is located above the glass plate. The existing door frame is provided with two symmetrical convex plate ribs, and both plate ribs are provided with slide grooves. The left and right ends of the glass plate are respectively located in the corresponding slide grooves. Since the two plate ribs on the door frame are convex, and one glass plate corresponds to two sets of molds, when the mold is assembled, it often hits the convex plate ribs, causing the plate ribs to deform. At this time, the glass plate cannot move smoothly in the up and down directions. Once the glass plate cannot slide smoothly into place, the mold cannot work normally. Utility Model Content
