Description of the invention 技术 The technical field of ^ Ming] I by water supplement ^ Ming is about a water-assisted injection molding method, especially refers to the use of | water 'blow, the device sequentially against the plastic raw materials located in the mold cavity, Implement procedures such as internal injection of hollow S gas to throw water and discharge it, to manufacture and mold plastic finished products with a thickness of "" r", average thickness, and reduced manufacturing costs. yPrevious technology] | Finished product driving = injection f molding method If you want to manufacture and mold a plastic with nitrogen in the hollow part, it can be achieved by injecting nitrogen into the plastic raw material in the mold cavity; only nitrogen: compressibility, often caused The lack of uneven thickness of the plastic finished product, | causes the high 'Ang = 意 取 #' 致使 具 #, the production of the plastic finished product of the empty part [invention] I close Ϊ: water: injection molding method [see section -Figure], which is opened by the I valve. 0: The mold cavity introduces the water flow c. The G position of the water-assisted device is blown into the gas to form the over-water auxiliary device. = Mold :: 模 以 达 = drainage of the auxiliary device | mold (4) Closed [Please refer to the fixed template (3) to make it into KG; the mold is inserted into the mold ^ After the mold is closed, please refer to the plastic kick material immediately Note: The volume of I has been subtracted from the hollow part in advance. Cut out the internal plastic materials $ 5, page 1231256 V. Description of the invention (2) Introduce water flow to the mold cavity through the water auxiliary device C: Drive the water with force from the water supply source through the water cylinder, pass the water needle and drain the water auxiliary device Valve, and then injected into the plastic material located in the cavity [ (See Figures 2 and 3 and Annex II]. The volume of the liquid entering the water-assisted device is equal to the volume to be hollowed out in the hollow part. The driven liquid-water force can push the uncured plastic raw materials and use Fill all corners of the mold cavity with an average thickness, and use the plastic product with a hollow part to form the mold [see Annex III. The drain valve of the water auxiliary device is opened. D: The plastic product with the hollow part is cured and the water auxiliary device is drained. The valve then opens [see Figure 4 and Attachment 2]; The water needle exits the mold cavity E of the water assist device: The water needle exits the mold cavity to separate the water injection port of the water auxiliary device from the close place of the plastic product. The demolding procedure of the plastic finished product is smooth; the gas is blown into the cavity through the water-assisted device. F: blows the gas from the gas supply source into the hollow part of the plastic finished product (please refer to Figure 5 and Annex IV). The function can force the water flow originally filled in the hollow part to be discharged quickly; Store the discharged water G: The water liquid discharged from the inside of the water auxiliary device will directly enter the water storage tank, and no longer return through the water tank The water source is used repeatedly; the drain valve of the water auxiliary device is closed. Η: The water valve in the hollow part of the plastic product is completely discharged, and the drain valve of the water auxiliary device is closed immediately. Open the mold I: The plastic product with the hollow part is opened because of the mold. Out of the mold cavity.
