An ejecting groove 21 is provided at one end of one side of the connecting plate 2. The driving rod 72 abuts against the core plate 4 through the ejecting groove. After processing, the cylinder 71 drives the driving rod 72 to eject the core plate 4.

[0037] As Figures 1-8 shown, in this embodiment, guide rods 9 penetrate through both ends of the connecting plate 2 and the mold closing plate 3, and limit blocks 10 are symmetrically arranged on both sides of the connecting plate 2 and the mold closing plate 3. Through the guide rods 9 and the limit blocks 10, the connecting plate 2 and the mold closing plate 3 can be limited, and their movement strokes in the vertical direction can be controlled.

[0044] Working principle: After injecting the material through the feed port 61 of the top closing plate 6, it is heated by the heating strips 81 on the hot runner plate 5 and then flows into the core plate 4 through the feeding member 13 for forming. Subsequently, the cylinder 71 is used to push out of the mold, and the nozzle 11 cooperates with the lifter 12 for demolding.

[0045] Through the above technical solution, the present application changes the original compression molding process to an injection molding process. The processing time for a single-piece product is reduced from the original 5-6 minutes to 15-20 seconds, and a plastic material that is easier to shape and more environmentally friendly is used, effectively reducing the processing time and production cost and improving the production efficiency.
