[0030] Reference Figures 1-2The utility model provides a kind of high-precision mobile phone composite board injection mold, including workbench 4, workbench 4 upper portion is fixedly connected with mounting bracket 10, mounting bracket 10 middle part is fixedly connected with hydraulic rod 11, and hydraulic rod 11 output end is fixedly connected with upper die 13, and workbench 4 upper portion is fixedly connected with lower die 12, and workbench 4 inside is provided with filter screen 6, and filter screen 6 lower part is provided with stopper 22, and workbench 4 lower part is provided with water tank 2, and water tank 2 outside is fixedly connected with water pipe 14, and water pipe 14 one side is fixedly connected with hose 7, and hose 7 outside is fixedly connected with shower head 8, and water tank 2 inside is fixedly connected with water pump 15, and water pump 15 output end is fixedly connected in the water pipe 14 one end, and workbench 4 inside is provided with stripping mechanism, and stripping mechanism is used to eject stripping to injection molding part. First control hydraulic rod 11 will upper die 13 and lower die 12 close tightly, using hydraulic rod 11 can easily control the closure of mould, greatly improve work efficiency, again material is injected into mould through feed inlet 9, waits for its injection molding, and then again through hydraulic rod 11 open upper die 13 and make product show. Then start water pump 15, and water in water tank 2 is sprayed by the shower head 8 connected by water pipe 14 and hose 7, so that mould and product are cleaned and cooled, also greatly improve work efficiency and protect the safety of staff to prevent being scalded, and the sprayed water will flow into the recess in workbench 4 due to gravity, and filter screen 6 is arranged in the recess, to prevent sundries from entering water tank 2.
[0031] With reference to Figure 1 And Figure 3 , stripping mechanism includes motor 3 and push rod 21, and push rod 21 is slidably connected in the middle part of lower die 12, and spring 16 is sleeved on the outside of push rod 21, and tray 18 is fixedly connected to the bottom of push rod 21, and motor 3 front side is fixedly connected to the outside of workbench 4, and motor 3 output end is fixedly connected with rotating shaft 19, and rotating shaft 19 front end is fixedly connected with cam 17. Start motor 3, drive rotating shaft 19, rotating shaft 19 drive cam 17, and when cam 17 rotates to a certain angle, it will contact tray 18 to lift tray 18, and spring 16 will be deformed, so that push rod 21 rises to lift the product, so that it is more easily stripped, and work efficiency is greatly improved.
[0032] With reference to Figures 1-2 , hose 7 lower part is fixedly connected with support 5, and support 5 lower part is fixedly connected with fixed frame 1, and fixed frame 1 outside is fixedly connected to the outside of water tank 2.
